Hi Andrew,
Yes, it could be a bad cable, but there are a couple of other things to
check, too.
Has the radome been removed (particularly if it was right around the time
you started to have the glide slope problem)? The glide slope antenna is
built into the radome, and the cable to the antenna must be disconnected to
remove the radome. Sometimes it doesn't get reconnected when the radome goes
back on.
The other thing to check would be the splitter that is somewhere between the
antenna and the two radios, probably right behind the instrument panel.
Regards,
Stan

I am looking for advice on how to troubleshoot the following problem with m

with the KI-525A HSI indicator. This is coupled to an STEC 60-2 autopilot
. Also connected to the HSI is a King KX-165 and Northstar M3 Approach GPS
.
The problem=2C which happened during my last flight is=3B when the autopilo

will either roll to the left or right all the way to the aileron stops. Th
e closer it is the bug setting the slower the roll and just about stops at
the bug. The same thing appears to happen in the NAV mode when driven by t

I have checked and reseated all connections on the turn coordinator=2C auto

Mike,
Same issue as what I'm having with my S-Tec System 30 except it is only to the
left.
S-Tec told me to check the outputs of my HSI (Century NSD1000) to match +- 5VDC
depending on which side of the bug you're on. Haven't been able to do that as
my GPSS module crapped out and I had to sent it in for repairs - it's back and
I haven't had time to test it again.....
I need to test that and the alt hold module - in case I need to reverse pins 3
and 4.....
Check with S-Tec about what the specs should be for your King HSI...
Let me know what you come up with...
Ralph

That sounds like a polarity reverse. Rather than going through all the
block connections why not just reverse the polarity of the aileron actuator
motor... Be sure to mark this change on your block interconnect diagram if
you made one.

The further you are off course the more deviation goes to the controller and
the more power is fed to the aileron actuator. The problem is your aileron
actuator is going the wrong way this can only be because either the inputs
to the controller from the HSI are reversed or the power wires to the
aileron actuator are reversed. One, not both, of these things are the
problem. I recommended reversing the power wires to the actuator forgetting
that most of the planes on this list are certified. For a certified plane
triple check the polarity of the controller inputs from the HSI to the
autopilot controller. If that is perfect, then reverse the polarity of the
two wires going into the aileron actuator. Do not change any other wiring (
assuming everything else works properly).

Woops.... if this only happens ONLY when the heading hold is selected then
the output from the HSI to the autopilot controller must be reversed. If
the auto pilot always reverses the correct input then the actuator wires are
reversed.

One guide for placing avionics is: "Which one do you touch most often?"
Put those that you frequently touch in the most convenient places, keeping

I guess the advantage of this arrangement is that you leave space on the top

one more calibration routine to sync the units? Is the sync to 150 degrees
ony for the VOR mode?

| Subject: | Avmap EKP IV and XM weather |
| From: | "annken100" <annken100(at)aol.com> |
I recently added the just released XM weather option on my EKP IV GPS. The problem
I'm having is that I only receive METARs and nothing else. I'm hoping someone
on this list has the same GPS and weather combo as I do so I can ask some
questions and compare notes. Please email me at annken100(at)aol.com I have spoken
with tech support from XM, Avmap, and WxWorx and so far I'm told that I
am one of only three people who has this problem. Oddly enough, the three of
us activated our receivers around the same time.
Thank you,

I have a KR 85 ADF with a KI225 indicator, using a KA42A antenna. The unit
receives the signal both while in ADF mode or ANT mode. The pointer on the
indicator just moves around slowly. I have tried another unit that works in
another aircraft but no change. Another indicator makes no change. I have
also tried another antenna and cable from antenna to indicator but no
change. All wiring looks good. What could the fault be?

Hello Gang,
I have a Northstar GPS 60 that has been working well until the other
week when it simply would not find any satellites. At start up it
runs through the self test everything OK then it starts searching for
satellites says it has 4, 5, 6, etc then has 0. It will come back
and find sats, navigate for a while then drop out again.
I am thinking this is an antenna problem, can teardrop antennas go
bad? can I swap with any GPS ant to test or do they have different
requirements? Is there a coax cable that is best? Or is the problem
elsewhere?
Any thoughts , suggestions would be appreciated.
Thanks
Bob

I would check the coax, more than likely it is RG-58, if it checks bad
replace with RG-142 or RG-400 and yes the antenna can go bad, not
very often but it can.

| Subject: | Matronics Email List Fund Raiser During November! |
Dear Listers,
Each November I hold a PBS-like fund raiser to support the continued operation
and upgrade of the List services at Matronics. It's through soley through the
Contributions of List members that these Matronics Lists are possible.
You have probably noticed that there are no banner ads or pop-up windows on any of the Matronics Lists or related web sites such as the Forums site ( http://forums.matronics.com ), Wiki site ( http://wiki.matronics.com ), or other related pages such as the List Search Engine ( http://www.matronics.com/search ), List Browse ( http://www.matronics.com/listbrowse ), etc. This is because I believe in a List experience that is completely about the sport we all enjoy - namely Airplanes and not about annoying advertisments.
During the month of November I will be sending out List messages every few days
reminding everyone that the Fund Raiser is underway. I ask for your patience
and understanding during the Fund Raiser and throughout these regular messages.
The Fund Raiser is only financial support mechanism I have to pay all of the
bills associated with running these lists. Your personal Contribution counts.
Once again, this year I've got a terrific line up of free gifts to go along with
the various Contribution levels. Most all of these gifts have been provided
by some of the vary members and vendors that you'll find on Matronics Lists and
have been either donated or provided at substantially discounted rates.
This year, these generous people include Bob Nuckolls of the AeroElectric Connection (http://www.aeroelectric.com/), Andy Gold of the Builder's Bookstore (http://www.buildersbooks.com/), and Jon Croke of HomebuiltHELP (http://www.homebuilthelp.com/).
These are extremely generous guys and I encourage you to visit their respective
web sites. Each one offers a unique and very useful aviation-related product
line. I would like publicly to thank Bob, Andy, and Jon for their generous support
of the Lists again this year!!
You can make your List Contribution using any one of three secure methods this
year including using a credit card, PayPal, or by personal check. All three methods
afford you the opportunity to select one of this year's free gifts with
a qualifying Contribution amount!!
To make your Contribution, please visit the secure site below:
https://www.matronics.com/contribution
I would like to thank everyone in advance for their generous financial AND moral
support over the years. I know it sounds a little cliche, but you guys really
do feel like family.
Thank you for your support!

I have a TruTrak 2-axis autopilot for sale. It has never been used. I
am selling it to switch to the Dynon autopilot since I already have the
Dynon EFIS.
It is a D-200VSG controller with DSP-B pitch servo and DSB-B roll servo.
TruTrak makes installation kits for many different aircraft.
The D-200VSG is not current manufacture but has the same capability as
the Digiflight II VSG (flat pack configuration). TruTrak still supports
the D-200 series. In fact, they recently upgraded the gyro board on the
controller at no charge despite having I bought it second hand myself.
http://www.trutrakflightsystems.com/instruments.htm
First $2250 takes it. That is basically the price of the two servos
alone. List for the current generation Digiflight II VSG is $4725.

| Subject: | List Fund Raiser |
A couple of years ago I implemented an automatic "squelch button" of sorts for
the Fund Raiser messages. Here's how it works... As soon as a List member makes
a
Contribution through the Matronics Fund Raiser web site, he or she will instantly
cease to receive these Fund Raiser messages for the rest of the month! Its
just that simple. Don't you wish PBS worked that way! :-)
I really do appreciate each and every one of your individual Contributions to support
the Lists. It is your support that enables me to upgrade the hardware
and
software that are required to run a List Site like this. It also goes to pay for
the commercial-grade Internet connection and to pay the huge electric bill
to
keep the computer gear running and the air conditioner powered on. I run all of
the Matronics Email List and Forums sites here locally which allows me to
control and monitor every aspect of the system for the utmost in reliably and performance.
Your personal Contribution matters because, when combined with other Listers such
as yourself, it pays the bills to keep this site up and running. I accept
exactly ZERO advertising dollars for the Matronics Lists sites. I can't stand
the pop-up ads and all other commercials that are so prevalent on the Internet
these days and I particularly don't want to have it on my Email List sites.
If you appreciate the ad-free, grass-roots, down-home feel of the Matronics Email
Lists, please make a Contribution to keep it that way!!

for the Lists.
Won't you take a moment and assure that your name is on that List of Contributors

at least - if not a whole lot more - valuable as a building/flying/recreating/entertainment
tool as your typical magazine subscription!

the List insuring maximum performance and minimal contention when accessing
List services. It pays for the regular system hardware and software upgrades
enabling the highest performance possible for services such as the Archive Search
Engine, List Browser, and Forums. It pays for 19+ years worth of online archive
data available for instant random search and access. And, it offsets the
many hours spent writing, developing, and maintaining the custom applications
that power this List Service such as the List Browse, Search Engine, Forums,
Wiki and PhotoShare.
But most importantly, your List Contribution enables a forum where you and your
peers can communicate freely in an environment that is free from moderation,
censorship, advertising, commercialism, SPAM, and computer viruses. How many
places on the Internet can you make all those statements these days?
It is YOUR CONTRIBUTION that directly enables these many aspects of these valuable
List services. Please support it today with your List Contribution. Its
one of the best investments you can make in your Sport...

Dear Listers,
The percentage of people making a Contribution to support the Lists this year is
currently lagging behind last year by approximately 21%! I'm hoping that everyone
is just waiting until the last minute to show their support... ;-)
Please remember that it is solely your direct Contributions that keep these Lists
up and running and most importantly - AD FREE! If the members don't want to
support the Lists directly, then I will likely have to start adding advertisements
to offset the costs of running the Lists. But I *really* don't want to
have to start doing that. I really like the non-commercial atmosphere here and
I think that a lot of the members appreciate that too.
Please take a moment to make a Contribution today in support of the continued ad-free
operation of all these Lists:

| Subject: | digital rpm gauge question |
| From: | "keithmckinley" <keith.mckinley(at)townisp.com> |
Hello,
I purchased an MGL E-3 digital engine gauge to display EGT. The gauge is capable
of displaying rpm as well.
Since there is a single wire to from the unit (for rpm) I would think it is impossible
to show the rpm on both mags as well as individually during a mag check.
I can connect to the P-lead of either mag and get an indication but it is only
for that mag of course.
Am I missing something.....
Thanks,
Keith

If you get a different reading from two mags, both of which are
connected to the same camshaft, you're not measuring RPM, you're
checking for a bad mag. You could put a double throw switch in the
line.

Hi Noel,
We have worked most of this out. I know it has been a few months. We are
going to externally mount the antennas. We did a trial test with a dummy
load and then with the antenna hooked to a long coax and tried different
external mounts and all the RFI went away. We are fairly certain then
that
all our trouble is radiated emission. I have some questions:
1. How far apart should the external antennas be=85 what=92s the
minimum
distance
2. Can they share the same ground plane as long as they both make
ground with it
3. Can the TXP antenna share the same ground plane
4. Do you have an antenna recommendation?
5. Should one be top mounted and one bottom mounted on the
fuselage
tail cone?

Tom:
Just a few Ideas.
Just as the radiating element of your antenna should be 1/4 wave length
the
ground plane should also be at least that size. If it isn't don't worry
you
can stick a ground plane inside your fuselage with contact cement using
aluminium foil for the ground plane itself. Make sure it is connected
to
the braid side of the coax at the antenna end. The ground plane should
also
be as close as reasonably possible to perpendicular to the radiating
element.
The advice you got to check out your antenna system sounds good to me.
Transmitters aren't too bright and when you feed their output to a
miss-matched antenna system the fool transmitter works harder to get the
signal out. This means it draws a lot more current and of course heats
up.
The end result can be a burned out final amplifier (expensive) or a
popped
circuit breaker. (Cheap if you don't reset it)
Most of the other things you mentioned can be easily attributed to the
same
antenna problem. High current draw by the transmitter will cause the
voltage regulator to cut in possibly to the point before an over voltage
indication.... BTW you generally get that OV indication after the
alternator has been shut down to protect it.
It just crossed my mind that I have seen high draw on a transmitter. It
occurred when there was a crack in the centre conductor inside the coax
to
the antenna. Do a continuity test on the centre conductor of the coax.
When you do that continuity test try wiggling the connectors while
hooked up
to the VOM. Your problem can also be caused by a cold solder joint or a
bad
crimp in a connector.
Finally my pet peeve is bad grounds. Aircraft electrical systems need
to
have as close to perfect ground as possible. You would be surprised the
effect of a bit of black corrosion under the grounding strap that
connects
your engine to the frame across the engine mount will have on your whole
system. Make sure any grounding straps are clean under the nuts/bolts
that
connect them to the various parts of the frame. Make sure there is good
continuity from the grounding posts behind your instrument panel to the
engine block. Also make sure the voltage regulator is mounted on a
clean
surface. Many newer solid state regulators require the case have a good
ground.
You may want to borrow another transmitter and temporarily connect it to
your antenna system and the AC power. If you get the same effect on
transmit then you will know for sure it is your installation and not the
transmitter itself.
The advice to get your antenna system checked out is capitol. Avionics
techs have equipment that can do amazing things. Ten minutes on a
Cushman
could end up saving many $$ chasing a problem.
To recap:
*Put your antenna system under the microscope. That's probably where
your
problem is located.
*Check the continuity of all grounding straps. a good idea to check on
an
annual basis.
*If possible try another transmitter (not a hand held) in your plane You
only need to connect the antenna and aircraft power and see if you get
the
same problem.
If this doesn't fix the problem then you are going to have to get some
local
expertise... Preferably with equipment. Good places to look for help
are
Telco, Amateur radio, Television stations. Only certified avionics
shops
should open avionics cases or make modifications to avionics systems.
You
should keep that in mind if you have a certified plane.
Where do you keep your plane?? if at YHZ you may want to contact Uli
Huber
at Atlantic AV in Springfield he has technicians who should be able to
get
you going in short order...... Bring money ;-)
Hope this helps.

Subject: Avionics-List: comm tx causing avionics fluctuations
Does any one have experience with comm tx causing transient changes in
their engine analyzers egt/cht and voltages in glasairs or other
fiberglass
airframes? As we continue to debug our panel this problem is now up for
a
solution. I have heard that it may be "antenna standing wave
reflections"?
Our vert servo on the TruTrak is affected during Tx as well. We assumed
that
the other systems being affected were due to the close proximity of the
comm
antenna coax and the aircraft charging system as they all run through
the
center console of our Glasair III for a short distance in close
proximity.
Maybe I am wrong and it is more to do with the Standing Wave Reflection?
Our other bugs caused by the comm. Tx are:
1. transient voltage rise on both buses from 14.1 to 14.6 (this is
a
real voltage change measured by and external meter)
2. egt and cht values decrease by 300 and 100 degrees F
respectively
(these are obviously not real temp changes)
3. Ray Allan trim and flap indicators flicker (the trim and flaps
don't actually move)
The following is something Tim Hedding of B&C alternators sent me:
1. Check the transmitting antenna systems for SWR. Check that the
antenna,
transmission line and transmitter output are of the same impedance and
that
the connections and ground planes are good. Use an SWR bridge or antenna
analyzer to check the antenna system matching / efficiency.
There must be some other glass airplanes out there that have seen some
of
these quirks.

I believe the recommended distance antennae should be is greater than three
feet. (for COM.Nav antennae) Some planes have two phased antennae for com.
The installation instructions will specify the distance between the
antennae. That is done on some installations to give a directional quality
to the com radio. VOR antennae are usually horizontal and therefore are
usually mounted on the tail of the plane.
XPNDR antenna are usually placed on the bottom of the airplane because their
primary purpose is to communicate with ground stations. They should also be
limited to about 200 mi in range so that they don't cause distance
interference.
The ground plane is actually a form of reflector so the short answer is yes
several antennae, even on several different frequencies, can share a ground
plane. In fact on metal planes the whole of the skin is considered to be
ground plane. Tube an rag planes the whole frame is considered to be ground
plane.
Transponders use different frequencies than con/nav antennae. Therefore
their antennae are shorter. Use the antenna recommended with your
transponder.
Com radios are usually vertically polarized antennae mounted on the top of
the plane where they can reach other planes and distant ground based towers.
So the long and short of it is Com on top.. XPNDR on the bottom and VOR
on the tail. GPS if you have it will have the antenna on top where it can
see the sky, RADALT will be on the belly of the plane. ADF goniometer
(loop) antenna can be either on top or bottom of the plane the same is true
of the ADF sense (long wire) antenna.
Without the aid of an avionics shop I wouldn't try to install an HF rig in a
plane... but if you do 80 meters is a blast at even 1000'.
Hope this helps

| From: | "skywagon" <skywagon(at)charter.net> |
My KT76 transponder sits on the bottom of my radio stack. As such, in daylight
flights, it's ambient cabin lighting sensor "senses" that it is operating in
evening/low light conditions and dims down the transponder radar pulse return
lamp such that it can barely be seen in daylight operation. The sensor is operational
as reflecting bright light on it, the pulse flash lamp comes up in brilliance.
I have not been able to find a schematic that shows this lamp control circuit.
I am assuming that that the circuit contains a bias control pot. that when located
can be tweaked to allow the pulse return lamp to blink at a higher intensity.
Any help would be greatly appreciated.....

I'm currently running Anywheremap on an iPAQ Hx4700 and I'm very pleased
with it. However, because the Hx4700's uses Windows Mobile 2003, I
can't
download the latest map program from Anywheremap; it requires WM5 or
higher.
In the past, people who upgraded their Hx4700s to WM5 had all kinds of
problems, but those problems were all supposed to have been taken care
of
with Microsoft's latest release, WM6.1. So the questions are: have any
Anywheremap/Hx4700 users downloaded WM6.1; how did you do it; and how do
you

Hello
My business partner and I own an aircraft maintenance company. We are working towards
the restoration side of the trade and would like to feature updated avionics
and electrical systems as an option to original equipment.
We have our company 1956 Tripacer that we are using as a learning tool and advertisement.
The plane is down to the bare frame and I am starting the planning
process for the electrical system.
We are looking for ideas on updating the electrical system. we plan on all new
wiring, single point ground, and possibly EFIS or a variation. The generator is
coming off and an alternator is going on.
We would like to replace the original nav light/dimmer combination switch and
possibly re-design the aux fuel transfer system which is a pull cable with a switch
(pull the knob - the cable opens the fuel valve and the switch turns on
the pump).
Parts for these older planes are getting harder to find and are quite expensive,
this is our reason for wanting to update the systems plus technology has given
us better products to work with.
This isn't an experimental plane so we will have to do paperwork on everything
we do.
I would appreciate your thoughts and comments
Gary

Nothing is impossible. There are a number of 6 cylinder Tigers out
there.
I just completed an STC for a completely new, firewall forward,
fiberglass cowling for a Tiger. It took 8 years (from concept to
completion) and over $100,000, but it's finished.
The only problem you might run into is the EFIS. Get a DER that knows
what he's doing (that's the hard part).
It might take a while but it will be worth it; if only for the
satisfaction of having done it.

I understand the concern of working with FSDO but there is no point in talking
with them until we have design data worked out.
Presentation, research, and fact are key in pushing major alterations through.
We have a good FSDO and my partner is a DAR and has worked with them extensively.
If we can present some good design ideas I think we have a good chance getting
approval.
With these old airplanes being restored to like new or better and an ever decreasing
supply of original parts I think the FAA is going to see more pressure to
allow updating and modifications.

Two schools of thought. Some owners like everything original and there are
a lot of shops rebuilding and restoring some of the original parts.
My personal Tripacer is being updated as well as I can without resorting to
all of the time and 337s necessary for a major conversion. New carter stack
panel, 60 amp alternator, led cabin lights, KMD 150 GPS, etc.
Would be interested in your updates.

Listers,

baud rates to my Garmin GTX-327 on both serial input ports 1 (db25

getting AirData Z-format from the GRT EFIS at 9600 baud into either of the GTX-327
serial ports, so the ports are good. The GTX-327 just won't seem to see

I recently had experience with a Garmin 425 GPS (a tiny one not
really for aircraft use) that claimed to put out RS232 compliant
signals.
What I discovered, with an oscilloscope, was a signal level that was
"low" at about +150 mV and high at about +4.5 V with a fairly high
internal resistance that had problems at 1 mA output levels. Without
careful grounding at the pins of the GPS the +150 mV was even worse.
RS232-C, which is the only official RS232 spec I can afford right now
calls for a negative going level for the low value and Garmin simply
does NOT meet that. There are some newer RS232 specifications around
that might describe Garmin's output level but when I asked all I got
was "RTFM" and the PDF manual simply says RS232 compliant.
I placed a 1.5 volt dry cell in series with Garmin's output with a
polarity that subtracted 1.5 volts from all signals. The resulting
data stream went negative and was acceptable to the old Macintosh I
was working with at the time. Some USB to RS232 converters would
work and others would not.
You seem to be talking about the Garmin as a receiver rather than a
transmitter and I have no idea how well Garmin's "RS232 compliant"
receiver behaves. I do doubt that you will get an authoritative
answer from them.

I've got my GX-60 hooked to both by MX-20 and 396 using the same serial TX
from the GX. When I set the flight plan on the GX it shows on both the MX
and 396. The flight plan page of the 396 shows the flight plan name as
"AVIATION IN". You can override it if you want to see something different on
the 396. Works great.

Thanks to those who answered. I had read (somewhere ?) that the GX50

sorry you can't test much at home on a transponder. Many units do not transmit
when in 'test' or 'ident' so even if you have a reception device handy you wont
find anything. However if you have an antenna connected and the unit gets interrogated
by other sources you may be able to hear the HV power supply whistling
under load as the cavity tube sends the reply. If its all hooked up to the
encoder you may be able to get a check from a friendly TCAS equipped plane or
a fellow aircraft owner that has a passive alert system available. Do not put
any equipment or body parts too close to the antenna unless you were about to
replace them anyway.

Hello Don,
sorry was not very active over Xmas and as I'm not seen any answer here
my experience. I'm running PocketFMS (as Anywhere Map is not so useful
outside the US) on my Hx4700 and did change autum 2007 from WM2003 to
WM6.0 and it was a difference which was noticeable, mostly by freeing
some memory. 6.0 for the 4700 is a non official version, but running
fine, very stable, faster and does not loose all your settings when the
battery goes flat.
You can see some perf tests here:
<http://www.pocketfms.com/phpBB3/viewtopic.php?f=4&t=3954>
The description how to upgrade is seen here
<http://forum.brighthand.com/showthread.php?s=151039929fbc914bba3cdba863cd00e4&t=246529>
(read carefully and reread before you start) I had some difficulties to
find the image, let me know if you can not find it I might still have it
somewhere.
Good luck and have fun!

Remember if your encoder is not TCAS and not mode C it possibly can give low
flying transport planes a good fright if you are anywhere near a flight
path. Best idea is to send the Xpndr to a shop for testing. They have the
proper testing apparatus and I generally only takes a few seconds. Easier
than that is to take a short flight and see if ATC copies your Xpndr.

The most expensive and least complicated route is to buy a new AMP
601966-1 crimper and AMP 601966-5 positioner from any of the online
electronics shops (Mouser, Newark, Allied). That'll set you back
about $600. Ouch.
More complicated and less expensive routes require a cross reference
of the AMP part #'s to MIL spec #'s. Those are as follows:
205089-1 Pin is a M39029/64-369.
205090-1 Socket is a M39029/63-368.
We use DMC tools in our shop. Pics can be seen at
https://www.dmctools.com/store/catalog.asp. You have a few options
depending on what style of crimper you want. These can be verified
using DMCs online cross reference tool to the M39029 part #'s:
The AF8 crimper needs the TP585 positioner for these contacts.
The AFM8 crimper needs the K13-1 positioner for these contacts.
The MH860 crimper needs the 86-30-1 positioner for these contacts.
Buying these tools new from DMC will set you back about $250.
However, they regularly show up on eBay for around $150. We got lucky
and found our AFM8 and positioner at a local military/electronics
surplus shop for around $80 and they work like new.
Hope this helps,
D

I=92m just thinking out loud here but the reason your Nav beacons and

I

not the com antenna alone.

I have the radios on the bench hooked up to a service monitor (a Marconi
2966). The service monitor was connected to the NAV antenna input for that
test. I got the same result on both the KX170 and KX170A, which is what
made me think it was a design issue.
I'm going to let the KX170A run overnight; I don't know how long the radios
have sat, so I'll let the capacitors re-form. When I first hooked it up, it
took about 7 microvolts to break the squelch; it improved to 3.4 microvolts
after running for 20 minutes or so. That's pretty anemic, but I'm not that
worried, since I mainly want to listen to the local traffic on CTAF.

Two double pole relays suitable for the 12 or 24 volt aircraft power.
Power coils from fused aircraft circuit and return the coils through
the tip pins of the two push to talk jacks.
Connect mike audio inputs 1 and 2 through one pair of relay contacts
to the two mike audio inputs to the radio. You could use only one of
the inputs but there might be a problem if both talk switches are
simultaneously activated.
Connect the PTT radio pin through the other relay poles so that it is
grounded whenever either relay is activated.
Or. . .
If you use voice activated intercom those features are probably built
into it. Just wire the aircraft for a single mike output from the
intercom.
Or. . .
Some microphones, mostly older ones, use a double pole switch so that
the mike audio is only present when its own talk switch is pushed.
They're terrible for use with an intercom.

Hi? ALL,
I recently have downsized my experimental aircraft building aspirations, and no
longer need my Blue Mountain EFIS unit ...... model Light Plus which retails
for $4,500 from BM. It is in flawless never used condition and I would sell several
hundred $$ less to find a buyer interested in this nice unit at a great
price. Make an offer and we can make a deal.
To check it out ......... go the the Blue Mountain website and see what this unit
can do.
Thanks,? DC

Bad link for me, but if it's anything like the Apollo, nee, Garmin
GNS-480 they're all standard or high-density D-connectors. You're
pulling the unit out of the tube and flying it at home by directly
plugging in the connectors to the rear of the unit, right? Just use
a good connector and don't damage any pins.

I don't know what your practice will consist of, but wouldn't the free
Garmin trainer serve that purpose better? See this for (very large) down
load:

I have this trainer on my computer and it works great -- probably better

I agree, with one exception: it's the non-WAAS version, and the included

Hello Guys, Aren't we getting a bit jumbled up here?
1) OC suggested Robin Hou use this page to download a 420 trainer:
https://buy.garmin.com/shop/store/downloadsUpdates.jsp?product=010-00412-01&cID=194&pID=301
2) Jay Maynard wrote: "I agree, with one exception: it's the non-WAAS

firmware is a version behind."
That puzzled me because that page led me to a WAAS version and it was
version 3.0 software for the 400 series trainer. Is there something better
and newer?
3) Kevin Carey wrote: "Garmin has available on their web site

the WAAS versions of the trainer with a software version of 3.0."
True enough, but that page is the 530 trainer. How would that work out for a
guy with a 420?
Robin Hou please write and tell us that we haven't led you completely
astray.

No. It turns out that's the version I have on my computer. It's still behind
my year-old 430W; I'm going to have to go out to the airport and see what
version the one in the airplane is running now.

It's the same trainer for all of them. There's an option setting to select
which unit you want it to act like.

Hi Tim,
I saw your write up and pix!
You said you liked wiring and interfacing and such, so can you tell
me what interface you used to the Chelton and what software mods
were needed.
The standard TIS-B and FIS-B I/O is described in the RTCA doc I cited,
but I don't see where NavWorx describes what they do.
Was the Chelton preprogrammed to take std ADSB or did they
work with the NavWorx guys to create an interface?
I myself would like to feed the NavWorx into my BlueMountain Gen4
system
Thanks,

Skip,
The device you want goes by a couple of names: diplexer/triplexer/coupler.
Spruce has them on page 488 of my 2005 catalog. If then don't have them
give Gulf Coast a call. Any real avionics dealer should be able to supply
what you want. By the way these device work great. I have run 2 VOR's and
2 GS from one VOR antenna. I have also installed them in various
configurations in at least 6 A/C without any issues. Good luck.

| Subject: | Terra TN200 problem |
To any Terra wizards out there, here's my setup:
Vans RV4, circa 1992.
One Terra TN200 (not "D") with GS, TRINAV head with Loran/GPS option
and GX50 connected, single dipole antenna mounted below tail, and
splitter for GS and VOR/LOC, with RG58 coax.
Problem: GS indications intermittently erroneous. I routinely fly the
ILS Rwy 30L approach into KSJC and have the opportunity to do so VFR
and check GS indications against published GS altitudes at the fixes
and the PAPI. Sometimes I won't get any GS indication until inside 5
miles.
Sometimes I get GS out at 15 miles, but it shows that I'm low
(about 1/3 up the scale) no matter where I am ref the actual slope. I
get no flag, the "I" is displayed, as opposed to an "L", and it stays
at that 1/3 low position until inside 5 miles final or sometimes closer.
And once in a great while I receive correct indications at 15 miles
and continuing all the way in.
Localizer indications are always correct and responsive, within
tolerance.
Station ID is clear and correct.
I checked at another airport, same results.
Questions: Shouldn't I get a flag? Shouldn't the "I" change to an
"L"? Is there an RF gain adjustment that needs attention? Where
should I look first?
Should I upgrade to RG400, as I have with GPS and Comm?
Do splitters go bad?

I don't intend to change any of the settings on mine at the moment. Still,
writing them all down seems like a very good idea. I've had a couple of ham
radios that I've done that with because they've been known for losing their
internal settings should the power spike at engine start or the like.
I suspect that, while Garmin may not know how to set up the 430W to talk to
my Zodiac's TruTrak Digiflight IIVSG, TruTrak probably does. Still, I'd like
to avoid the necessity. There's also an Aspen PFD in my future, though not
for a while yet.
At some point, though, I plan to add a connection from the 430 to my 496 for
flight plan crossfiling, and that will need to be enabled via setup.

It surely is possible. But safe and legal? Probably not.
The problem is that a metal part you choose to use as the radiator
won't work if it's grounded to the rest of the airplane. Designers
and FAA rules like "bonding" between all metal parts to reduce radio
interference and to prevent sparks that might ignite something.
Required bonding would make an antenna fail.
You could think about using tuned or just inductive bonding straps
that would act as insulators in the frequency band of interest.
You might also think about a negative antenna. It's possible to cut a
long skinny hole in, say, a vertical stabilizer in a way that the
absence of metal, in the ground plane that is the rest of the
surface, can be excited as an antenna. I have personally done that,
at 244 MHz, in tail fins of sounding rockets but I suspect it would
be a PITA in an airplane that needs not to develop cracks in its skin.
If a major part of the aircraft is fiberglass anyway you might get
away with using an aluminum framing part that is inside.

Problem there is the airframe is grounded to the battery and from there the
case of the transmitter etc. The radiator for the antenna needs to be
insulated from contact with the ground or it will short circuit. Of course
you can put a big resistor across the feed line and the frame of the plane
and turn the whole thing into a dirt big dummy load. That won't hurt your
transmitter but you won't be heard either.
The ground is still needed as a ground plane which directs the outbound
signal.
Sorry to tell you the best thing is still the vertical 1/4 wave antenna...
for a metal plane.

My recollection of the Sigtronics is that they just allow the audio
from a comm radio to be mixed in wiring with the intercom audio. No
switching is provided "because I sleep better that way".
You should be able to use the transmitter for a test with the
intercom turned off. That way you would be absolutely sure any
sidetone is coming fro the transmitter.
If that doesn't work you should also be able to connect the mike to a
"standard" mike jack and the phones to a "standard" phone jack but
you might need a mike with a push-to-talk switch on it. You can make
a PTT by grounding the tip of the mike connector. That's the tip of
"ring, tip, and sleeve of the three terminal connector.
The CP125 does not generate any sidetone by itself. The Sigtronics
drives the headphones but, although it's quite the same, it's not
called sidetone.
The war department's problem with distortion could well be the
presence of audio from the Sigtronics being mixed out of phase with
sidetone from the transmitter.

First of all side tone is only in your own head set. It takes The same
signal that is fed to your transmitter or audio panel but sends it back to
your own headset so you can tell how loud you are speaking and if you are
intelligible.

Thanks, that's helpful. Here are a few more questions:
When I talk to the Sigtronics (comm radio off), I hear myself
(sidetone). Is that coming from the Sigtronics ? If so, then I'm
guessing that both the intercom and the COMM radio are putting out a
sidetone, when I tranmit. If they are "out of phase", that would
explain the distortion. Is there a reason why I shouldn't disable the
radio's sidetone and just rely on the intercom sidetone? I almost
always fly with the intercom on.

The intercom really ought to be turning off its output to the
headphones while a transmitter is keyed. It appears that it is not
doing that. Intercom audio is being sent to all headphones at the
same time. Strictly speaking, sidetone would be sent only to the
headset that has its microphone activated.
Are you , perhaps, keying the transmitter without telling the
intercom about it? A push to talk switch on a control yoke might be
doing that.
The sidetone from the transmitter is derived from a point very late
in the circuitry and is an indicator that the transmitter is working
pretty much properly. If you turn that off you would lose a failure
indication.
It's been almost two decades since I have had a Sigtronics apart and
I never owned one. I'll have a look at my records later today. There
might be a schematic around.

I found a schematic.
The SPA-400 uses diode isolation to activate the transmitter key. Activation of
the transmitter without going through SPA-400 pins 2 (pilot) or 10 (copilot)
will not be recognized by the intercom.
The intercom normally removes power from its headphone amplifier when either the
copilot or pilot push-to-talk key is pressed and diodes see that the aircraft's
push-to-talk system is also activated.
The output of the audio amplifier goes through 1 1 microfarad capacitor and a 100
ohm resistor to the aircraft's headphone bus, The 100 ohms allows for the audio
from other sources - like a radio or audio panel - to be connected to the
same bus where the audio signals are mixed.
A part of the on-off switch connects the aircraft microphone bus to the SPA-400
when it is turned on but reconnects mic bus directly to the pilot microphone
when off.
I'm now betting that the Gordon's problem has to do with his microphone jack being
wired so that he grounds the aircraft push-to-talk wire directly instead of
going through pin 2 of the intercom connector.
If I'm wrong there is a diode failure inside of the intercom, probably CR-7.
Off line at dmcnutt(at)macnauchtan.com if you want to talk in more detail about the
schematics. I'm not sure about copyright and non-disclosure issues.

Its unlikely that heat will cause both items to fail. You didnt say what aircraft
it is or what other equipment is stacked below your problem gear, or what climate
you are operating in.
LCD displays normally freeze when it is cold, go dark when they are too hot. Digital
electronics can halt from operating this is more often associated with bad
design bugs (these devices are the ones that the manufacturer has belatedly
required fitting of a large capacitor to the supply leads, a separate power master
switch, or both), humidity, bad power supply such as a neglected battery,
surges in the charging system, or just turning it off and on a dozen times when
you start the plane.
If you think it is overheating, buy a small indoor/outdoor digital thermometer
and tape the probes to the rear of the devices. check against the TSO data or
manufacturers recommendations 50 deg C or 120 F should be acceptable.

As an aside=2C I was able to link the AVMAP GPS to my D-180 and will use it

I can send you a picture of my panel and compass shelf if you want. Contact

Turning on then off all electrical devices would occasionally show up as a

Rotating the control stick=2C pushing pedal=2C etc. no change.
I was getting pretty proud of myself.
Then I closed the canopy. The compass dipped to 209.
Which again goes to show there is no really good spot on the RV-8. Where I

it is still pretty good as the canopy doesn't move once it is closed.

I was finally able to replicate the problem with the primary alternator, secondary
alternator, and more importantly - running on battery power alone.
Contacted Garmin and they suggested I send the unit in - they replaced the display
head and it is on its way back to me.

I have installed a Rotax 912 ULS in a Highlander and have used VDO oil
pressure and oil Temp. gauges. I have connected the + and - and the
sender wire, as shown on the wiring diagram, but I am showing a ground
short between all the pins and the power buss bar. Has anyone else run
into that problem or can Bob shed some light on the problem? I've run
out of ideas, and I haven't talked to anyone else that knows anything
about the problem. Any help would be appreciated.

| Subject: | Lear L2 autopilot removed |
Long ago I gave up maintaining a Lear L2 autopilot that was installed in my 1957
Piper Apache. I believe that, as of this week's annual inspection, all of the
scattered components have actually been removed from the aircraft. It was a
three-axis autopilot with selsyn pickoffs on elevator and ailerons. Approach coupler
and altitude hold worked in its early days. The attitude and heading gyros
with pickoffs are no longer available.
Having worked on the box for a couple of decades I can guarantee that it will never
become airworthy again. The 300 volt rotating motor generator and the magnetic
clutches are shot. It's all done with vacuum tubes and the sockets were
giving me pains.
If anyone is interested, perhaps for parts to support a still-working unit, please
contact me at user dmcnutt with the same domain as my list address. I'm willing
to pack it up but you would have to pick up the cost of UPS or other shipping
from zip code 80919. I estimate about 75 pounds.
In a week or so I am going to extract the cute things - like selsyn motors - and
junk the rest.

Folks,
I have a Narco AR 850 grey code altitude reporter. I would like to connect it
to two devices (GPS and transponder) instead of just the transponder. The serial
port on the GPS is being used for something else and it has grey code lines
also.
Both the GPS and transponder have diode suppression in the grey code lines in order
to prevent an off unit from dropping the signal to low.
What say ye.....can I do this - or will smoke escape....?
Thanks,
Ralph Capen

I suspect that the gray code from the GPS is an output rather than an input. At
the very east you would have to get design information from the folks who designed
the GPS.
The Narco interface emulates a "standard" encoding altimeter which simply grounds
the wires to indicate a one bit. It's not to be confused with Intel serial
port or an RS232 type of connection.

5/30/2009
Hello Matt, Thanks for your tool tip. Here is another tip that you can
distribute to the RV people if you will (I am not on their lists).
Where ever possible abandon those abominable Phillips drive machine screws.
Instead use Torx (six lobe) drive machine screws.
Every builder who has done this has thanked me profusely for the suggestion.
Torx drive inserts are readily available and with an electric cordless screw
driver are very quick and effective -- vastly superior to Phillips drive.
You can obtain Torx drive screws in a variety of sizes from Microfasteners.
See here:
http://www.microfasteners.com/catalog/products/SSCFCMXS.cfm
(Note that these flat head screws have a true aviation use 100 degree
countersink angle, not the common hardware store 82 degree countersink
angle)
and here:
http://www.microfasteners.com/catalog/products/SSCSBXS.cfm

PS: Thanks again Matt for making the Matronics lists available to us -- they
are of great value.

Subject: RV12-List: Must-Have Tool Tip...
Dear Listers,
I don't know, maybe everyone but me already knew about this little gem of a
tool,
but in case you missed it, I thought I share. If you don't have one of
these,
run - don't walk - down to your local Home Depot or Ace Hardware store and
get one! All of those #8 screws in the RVs are a giant pain to work in and
out
and some are just impossible to get to. I've been using this little guy on
the RV-8 project and can't image not having it now. The bendable shaft is
really
strong and you can bend the heck out of it without impacting the torque.
Its about $13 at Home Depot which is a great deal considering how handy it
is.
Here's a link to it on the Ace Hardware web page. I also attached a picture
of
mine attached to my Dewalt electric screw driver.

Does anyone know what pin 6 of J401A of the Narco Com 11B is?
My pin out drawing shows "N/C". However, the aircraft installation I am
working with has a wire at that location which I cannot figure out where
it goes.
I am removing the 11B and replacing it with a different unit.

On the COM11A pin 6 of J401A is called PHONES & SPEAKER GND.
It is internally connected to the case of the unit. It looks like a possible way
to limit ground noise in audio systems caused by audio frequency currents in
the airframe. Check to see if the speaker or the phone jacks are insulated from
airframe ground and wired to return current to pin 6.
And. . . A COMM 11 B might be different.

Is there a reliable and INEXPENSIVE crimp tool out there for the ITT pin sockets
Garmin PN 245-0022 and 245-0027 20 to 24 AWG?
These are in a 162-0100 or 162-1575 15 pin Dsub connector shell. I haven't any
conversion list for these Garmin part numbers.The specified tool for the 245-0022
is Astro 615708 w/positioner 616356 and for the 245-0027 ITT/Cannon (regular
duty) 995-0001-585 crimp tool (M22520/1-01) with locator 995-0001-244 (TH25)
or heavy duty 995-0001-584 (M22520/2-01) with locator 995-0001-604 (M22520/2-08)
and also insertion tool 274-7006-000 (CIET-20HD).
The Dsub shell that came with the radio is marked X ITT 0903 DAMAE 158. The pins
that came with it are colored silver for the longer socket end and copper on
the short wire insertion end with three color rings starting at the end with
orange then green then black or navy. The stepped band for locking in shell has
a small hole drilled into it.

Roger,
You did not mention why you did this resistance check in the first place.
What meter problem did you have?
The meter is supposed to measure the resistance of the probe using the
supply voltage. An R check of the meter itself might be meaningless

Anyone know what these things are inside?

Where can I get a reader (other than the Jeppesen Skybound thingy)?
Does anyone make a PCMCIA adapter for it?
My Apollo GX60 just bit the dust - no repairs available for the screen and the
rest of the machine works fine. I'll be trading in in for a GNC420W - quite painful.....
I really want to have spare cards like I had with my GX60...I really don't want

How much is Garmin going to credit you for the GX60?

Interesting thought - I'll look closely at it when I get it.
The standard discount is $2000.
I can't see anything actually broken - the display just quit working.
The radio still transmits and receives and the GPS still gets signal and
sends info to the MX20....just can't do anything with it....

Actually, this (AeroElectric-List) is the ideal forum for asking this
question.
This topic has been hashed out extensively on the aeroelectric list. If you
are interested in better understanding the situation go to the aeroelectric
archives and search for "encoder approval". You will find many entries under
this search phrase and there are other search phrases that will also
generate past postings on this subject.
To save you some time searching take a look at some of the postings in
August , 2006 with the subject "encoder approval" or "non TSO'd encoder".
You received some good advice in response to your posting copied below --
just go to another agency capable of performing the required 14 CFR 91.411
"IFR certification" tests and have them perform the tests and provide the
paper work. You'll be joining hundreds of other amateur builders happily
flying IFR with non TSO'd altitude encoders that have passed the required
tests of 14 CFR 91.411.

That is not entirely true. In defense of your local avionics guy he is
taking the same position that FAA headquarters took on the altitude
encoder -- that is, the altitude encoder must either be TSO'd or be tested
in accordance with 14 CFR paragraph 91.217 (b). The tests that FAA
headquarters described for compliance with 91.217 (b) are very elaborate and
extensive.

Subject: AeroElectric-List: IFR Certification
This may not be the ideal forum for asking this question, but I'll try it
anyway.
I want to certify my RV-8 for IFR flight. I know the FARs - I've looked at
them.
I have the Blue Mountain EFIS One as primary instrumentation.
I have the Blue Mountain EFIS Lite as a backup.
Both EFISs are on different electrical busses - the main and the standby.
-
which can be tied together, if needed.
I asked a local avionics guy about doing a pitot-static and transponder
check for IFR. He said I would have to install a separate altimeter and
encoder in order to get IFR certification. The EFIS has a built-in encod
er.
Has anyone else encountered this obstacle?

Hello Frank, You wrote: "Why pay twice if you don't have to?"
I agree. To determine if a flight without a transponder is legal go to 14
CFR 91.215.
Also note that permission for a flight without a transponder can be obtained
as described in 91.215 (d).

Hello Ira, You wrote: "If the boss at your local shop does not understand
the

I agree that finding another shop is the best way to resolve this situation.
However outright condemnation of the boss for "not understand(ing) the
regulations pertaining to OBAM aircraft" is not warranted.
1) The issue is not OBAM (amateur built experimental aircraft) versus
standard type certificated aircraft.
2) 14 CFR 91.217 applies equally to both of those kinds of aircraft.
3) The fundamental issue relates to TSO'd versus non TSO'd altitude
encoders.
4) Note that 91.217 applies to flight under VFR as well as flight under IFR.
5) Headquarters FAA is in agreement with the boss's position of not
approving a non TSO'd altitude encoder unless the tests required by 14 CFR
paragraph 91.217 (b) have been accomplished.
6) FAA Headquaters says that the tests required by 91.217 (b) are far more
complex and demanding than the tests required by 91.411 and the associated
appendicies of 14 CFR part 43.
7) Some people dispute FAA Headquarters position on this issue, but no one
to date has adequately challenged them to change their position.
8) My current recommendations on this issue are:
A) Understand the issues. (Hence this posting to you and fellow builders).
B) Let sleeping dogs lie because if FAA Headquarers really tried to enforce
their position it would cause chaos in the amateur built community because
of the large number of non TSO'd altitude encoders already flying, being
built into aircraft, and being manufactured.
Please let me know if you have any questions. Thanks.

Hello Ira, Thanks for your input. You wrote:
1) "For VFR into B, C airspace the BMA should be fine according to my
reading of the regs."
Note that the wording of 14 CFR 91.217 makes no distinction between the
requirement for either a TSO'd altitude encoder (91.217 (c)) or a tested
altitude encoder (91.217 (b)) for mode C operations (automatic pressure
altitude reporting equipment) under IFR or VFR.
Further, no class of airspace is excluded from the requirements of 91.217 by
the wording therein.
Can you cite some regulation that says otherwise?
2) "I treated my airframe to a brand new Sandia SAE5-35 TSO'd blind

A valid solution. When people have attempted to get the assistance of EAA to
change / clarify FAA Headquarter's position on this subject that is what EAA
has recommended -- just install a TSO'd altitude encoder.

Congratulations. After decades of flying many different types of aircraft
with many different locations for the head set jacks I came to the
conclusion that locating the jacks behind the pilot and copilot seats was
the best solution. I built my airplane that way and it has worked great.
When the pilot's jacks are behind the copilot's seat and the copilot's jacks
are behind the pilot's seat it makes it possible to both see and manipulate
the plugs while seated and strapped into your seat. I have used this benefit
many times.
Also the plugs are not banging into your knees while plugged into the
instrument panel and the wires are not dangling across your lap.

| Subject: | Fuel Flow - Hoskins FT 101 Fuel Flow not working |
| From: | "rogrbal" <rogrbal(at)yahoo.com> |
Hoskins FT 101 Fuel Flow not working:
1. Lights stay on - all zeros
2. Unplugging connector in rear gets it working for a while, then it goes to #1
state again.
3. Resetting by doing #2 does not carry forward any fuel used between resets.
4. If reset it every time it goes to state #1, it will accumulate all the fuel
used while working. Only missing that used while in state #1.
Since it always shows some power applied, I do not think this is an intermittent
power problem.
Since it accumulates, I do not think this is a problem in the wire going to the
battery for residual power to retain accumulated fuel.
The transducer has three wires to it, maybe one of them is the problem.
Since doing #2 always fixes it, maybe the problem is in or near this plug?
Any ideas help??
Wiring diagram is available at
http://www.instrumenttech.com/productsupport.shtml
Look in the POH for the FT101A. It shows the plug pin diagram. Although I have
a 101 the only difference I can tell, is that the type reading - gallons, pounds,
etc. - is user resetable vice manufacturer set.
Thanks for your ideas. Need to fix it tomorrow - Sunday 7/19/09

The ELT antenna might work but is unlikely to meet the installation standards for
VSWR. Thin radiator with loading coils and no base impedance match is a hard
task to get right. The ELT only had to work at 121 / 243 MHz. For Com you need
118-136 Mhz and dont want response at 243 MHz, that should be suppressed.
Cant be specific about the Cessna antenna unless you know the manufacturer part
no. such as Dorne-Margolin (DM.....) most of these are very suitable antennas
and fit with a cork gasket to the fuselage AND a doubler plate where the 4 nuts
mount the antenna so they have a good grounding via the mount plate.

I recommend putting a ground braid on one of the nuts you would use to
attach the Cessna antenna to the airplane. That antenna should give you
better service than the ELT antenna which is designed to operate best at one
frequency only. The Cessna antenna should also be a bit faster on the
outside of your plane.

OK Noel, I'll do that when I try that antenna.
Because the ELT antenna was already mounted, I took the easy way and tried
it with the com.
The frequencies I used were 119.3 to 123.0 and the reception was as good
as I've ever had with any radio (it is a KY-97). Transmission was just
fine too.
Will still try the other antenna.
The tray and board for the 97 looks exactly like an Icom I have. Are they

Here is what 91.413 says:
"91.413 ATC transponder tests and inspections.
(a) No persons may use an ATC transponder that is specified in 91.215(a),
121.345(c), or 135.143(c) of this chapter unless, within the preceding 24
calendar months, the ATC transponder has been tested and inspected and found

(b) Following any installation or maintenance on an ATC transponder where
data correspondence error could be introduced, the integrated system has
been tested, inspected, and found to comply with paragraph (c), appendix E,
of part 43 of this chapter."
It would appear that if you could satisfy yourself in some manner
(preferably documented) that "data correspondence error" could not be
introduced either by the repair or your subsequent reinstallation then no
Appendix E recheck would be required.
First flights after reinstallation should include some airborne check of the
system with ATC.
Why not ask the people who just did your check what their opinion is --
realizing that it may not be entirely unbiased.

flight, the transponder acted up. I had it pulled and sent off for repairs
and it is due back Monday with a fresh 8130. Will I need another
transponder/encoder cert IAW 91.413? Don

If the transponder comes back with an 8130, then it has been tested
IAW manufacturers specs and is ready for installation. So you will not
need another cert.

| Subject: | Navaid AP1 - full left aileron |
| From: | "zwakie" <mz(at)cariama.nl> |
Not sure if I can provide proper information on my little problem, but here goes
hoping that there's someone out there that can help me out.
I have a NAVAID AP1 with Smart Coupler II LE installed in my Europa. It has functioned
without trouble so far.
Ever since some work was performed behind the panel, the control head initiates
full left aileron when I activate wing leveler (WL), and the servo does not stop
when it reaches full deflection (the servo clutch then slips). Same thing
happens when switching the control head to track (TK).
My guess is that during the panel work some wire was disconnected or loosened.
Tonight I have checked wiring the best I could without fully taking out the panel,
but could not find anything amis.
Did anyone ever experience the same thing, and if so, what was causing it?
Thanks.
Marcel

Folks,
I'm just under 31 hours in to my test flying and have been trying to
make sure everything in the panel is working properly.
I'm trying to get the SL30 to power the S-TEC-30/GPSS autopilot (through
the Century NSD1000 HSI) - and it doesn't seem to want to play. In the
test mode, I can get the to/from, left/right, up/down, and NAV/GS flags
to do what they're supposed to so I'm pretty confident that the wiring
is OK. I can also tune in and hear the morse for the VOR station and
verify the correct radial (with another NAV radio that isn't hooked to
the autopilot) and the SL30 correctly displays to/from station and
radial on it's face - So I'm thinking that the radio is working OK.
Obviously, I need to break out the user manual for this thing - and
maybe brush up on my VOR navigation techniques (but I was able to verify
station and radial with another NAV radio). I think that I may also
need to call Garmin/UPSAT/Apollo/IIMorrow tech support...after I read
the manual.
What do you think - what are the chances that my radio display output is
hosed? It needs to go back for the SB fix anyway - so I may just bite
the bullet.....
Thanks,
Ralph

| Subject: | radio noise on xmit & xponder interrogation |
My friend Tim (who does not inhabit this list) has had a problem
arise with his comm radio that seems to have arisen suddenly, without
any changes to the installation.
He has a MicroAir 760 comm radio, with a FlightTech ITC402P intercom,
installed in a Europa.
Symptoms: intercom works fine, other stations' transmissions heard fine.
When either (P1 or P2) of the PTT buttons is pressed, a loud
distorted noise immediately occurs in both (noise-cancelling)
headsets. The words of the person speaking are barely discernable
through this. However, anyone listening to the transmission on
another comm radio hears the voice OK with no distortion (well, no
more than usual on any airband R/T!). So, the bad stuff is only
happening on the sidetone circuit, not on the signal going out to the
transmitter.
A noise also occurs when the transponder is interrogated. It's
usually not quite so loud as that heard with the PTT, and sounds like
white noise in character. This does seem to come and go - on a recent
trip we got so fed up with TSST, TSST, TSST at irregular intervals in
the headphones that we turned off the xponder on the outbound leg
because we couldn't concentrate. On the return leg we tried it to see
if it was still happening - it seemed considerably quieter and then
after some time ceased to occur at all (we were still getting
interrogated).
However, the distorted sidetone problem remained unabated.
These may be 2 separate things but it's suspicious they have
materialised at the same time.
I'm a bit puzzled as to why this should have suddenly sprung up. My
feeling is that it may be some poor earthing or poor screening in the
microphone leads. But it would need to be somewhere common to both
headset circuits as it is affecting each equally.
We are planning a longer trip this weekend (3 hours each way) and
will need to do much more talking this time. If there was a simple
fix to try before then I'd love to hear about it!
regards
Rowland

Likely problem is RF getting into the intercom, so check earth braids there first.
Ferrite beads placed over certain cables may help, but this cure is reserved
for dealing with improper equipment or installations.
The Microair radios do, as part of their "normal" function, transmit noise coming
from both mics regardless of which ptt was pressed, but this noise is minor
(with a correctly adjusted mic gain) and not the type of RF feedthrough noise
you describe.
I'm not quite sure whether his radio has also its own built in intercom, which
should be disabled, or used instead of the external intercom.

| Subject: | SL-30 problem - on to the next phase |
Thanks to those that responded to the initial post.
Looks like reseating everything got things working - now I need to learn what it
does and how to use it.
Here's my configuration:
S-Tec 30 dual axis autopilot with GPSS steering module.
Century NSD 1000 HSI
SL30
GNC420W
Anyone else out there with a similar configuration?
I am now able to get the SL30 NAV portion to display on the NSD 1000 which sends
the signal to the GPSS module for tracking and I can get it to turn using the
needle pointer. It doesn't seem to track very well in either the LO-TRK or
HI-TRK modes. After getting back from my test flight and reading...the manual
says something to the effect of starting within 10 degrees of the selected radial
and within one needle-width before engaging either of the TRK modes. I didn't
get this close before engaging the LO-TRK and it didn't seem to track well
at all. Is it really that sensitive in the setup requirement? Does it really
track well if it is set-up properly first?
Following a GPS course is really tight and I am really happy with that feature
- it does a real good job with the set-up and intercept all by itself. I am hoping
that the VOR/LOC tracking is as good...even if I have to set it up first.
As before, your input is appreciated,

Have you fitted the large (approx. 25,000 uF) capacitor to the regulator DC output?
This is covered in some of the Rotax info and installation manuals for some
of the homebuilt market radios. best to use a 105 degree C rated capacitor
and not in the cabin area.

If the noise can be described as a whine you may have a bad diode in the alternator.
I donno about the Rotax but perhaps it has diodes mounted externally?
One test is to see if the pitch of the whine changes with engine speed. Another
is an oscilloscope connected to the power bus.

I pasted your 1st message into this one to get all the symptoms together.
What kind of noise? Is it 'white' noise like you'd hear on an AM radio
tuned between stations, or an old TV set to an empty channel? If so,
does the radio's volume control have no effect on the noise volume? If
no effect, have you checked the nav section's volume? I've actually seen
this happen to people on a couple of occasions with combo nav/comms. The
nav (noise) volume can overwhelm everything else in the radio.
If it's not white noise, and the nav volume is in fact turned down, and
the comm volume is in fact turned down, is it a hum or buzz? If so, is
it still there if you unplug your mic cord? If so, it might be that the
audio output of the radio really does have a problem.

Hi Charlie,
First of all, thanks for responding to this newbee's question!
ceengland(at)bellsouth.ne wrote:
> What kind of noise?
Very similar to what you can hear in the WAV file in this ZIP-file, yet frequency on my radio seems to be a bit lower than in this sample: Sample White Noise (http://www.dogstar.dantimax.dk/testwavs/white.zip)
So yes it is white noise.
ceengland(at)bellsouth.ne wrote:

Negative. I did however notice that there was a slight drop in volume when pulling
the COM kHz selector knob or the NAV IDENT knob.

Not sure if I have this checked, will do it next time at the hangar.

Don't know, will check as well.

Don't know either, will have to check.

Let's hope we won't have to reach that conclusion [Wink]

Marcel,
To get help in troubleshooting, it's helpful to keep the communications (and troubleshooting
steps/results) together and in sequence. If someone new sees one
of the posts & wants to help, they need to see all the symptoms & what's already
been tried.
One thing I forgot to mention in the previous post is to simplify the
system. You mentioned 'problem is outputting to the headset through the
intercom'. Have you turned off the intercom while checking? If the
system is set up correctly, the radio should be audible through the
pilot's headset with the intercom turned off, and you should be able to
transmit with it off, also. With the intercom in the circuit, that's an
extra component that could be causing your problem.
Another thing I forgot to mention that may be a really quick check, is
to find another a/c with the same radio & swap yours into the other
a/c's radio tray. If your radio actually has an internal problem, you'll
get the same symptoms in the other a/c. If the problem is outside the
radio (installation or a different component, like the intercom), then
your radio will work normally in the other a/c.

Hi all:
Maybe you can help with my transmit problems. I have a UPS Aviation
Technologies (now Garmin AT) radio stack with SL-30 Nav Comm, GX-65
GPS/Comm, SL-70 transponder and SL-10MS audio panel (actually a PS-6000 with
UPS AT nameplate). I checked out everything according to the installation
manuals while the airplane was sitting on the ramp and the engine NOT
running. Now that I've been flying a lot, I'm getting a crackling in the
sidetone and when I look at the "TX" light on the radio it's flickering as
if someone were pulsing the press-to-talk switch 4-5 times per second, even
though I'm holding the PTT down tight. This happens on both radios and
people in the pattern say I'm breaking up and garbled. I've tried several
things looking for a solution, they are:
1) Turn down the MIC gains on both radios (in steps, a little at a time,
over several flights). In the end I had them turned down so much I couldn't
get a side tone in the earphones and suspect no-one could hear me at all.
2) I tried a couple different headsets (inexpensive non ANR types,
Sigtronics and Pilot Avionics units, both around 15 years old but well taken
care of and worked just fine in the Cessnas I used to rent). No joy.
3) I tried both headsets with and without foam muffs over the microphones.
No difference that I could tell with or without the muffs.
4) Placed ferrite beads over both coax lines running to the transmit
antennas (about 3/4 of the way down to the antennas, don't have access to
the base of the antennas right now, but will when I remove the floor panels
for annual inspection). No help!
5) Shut off the field in my B&C LR-60 alternator (with external regulator)
to operate on battery only. No change (I'm using forest of ground tabs ala
AEC philosophy and I'm NOT getting alternator noise in the reception of
either radio so I didn't expect this to help but it was easy to test).
6)Since I used fine (24 gauge 5 condutor MAC servo cable, no shielding) wire
to take the PTT signal from the PTT on the control stick to the pilots mic
jack, I thought maybe that was causing a problem so I tried using the
passengers PTT (wired with 22 ga shielded tefzel) instead of the pilots. No
change.
7) The audio panel has a built in fail-safe feature that routes the PTT and
mic/earphone signals direct to the number 1 NAV/COM in the event of audio
panel failure. I shut off the audio panel and tried that. The NAV/COMM TX
light comes on but still flickers and is crackly so it's not that. I of
course could not test the #2 radio this way but would expect it to be the
same.
Transmit antenna location is under the belly of the airplane (all metal
RV-6A). Two Comant bent whips about 40 inches apart just aft of the wing
spar.
The GPS portion of the GX-60 and VOR/ILS portion of the SL-30 work just
fine. Comm. reception on both radios is loud and clear (at least I can hear
people in the pattern even if I can't talk to them).
When I originally ran through the installation checkout I left the settings
on the radios at the factory recommended (transmit worked fine so I left the
settings alone) and have been making changes to the Mic gains only. These
are computer controlled radios so I'm wondering if I need to adjust any
other parameters such as squelch (no pots to control squelch like the old
days) after making the Mic gain adjustments. Could the two be somehow
related through logic in the computer program that runs the radios?
I'm really stumped, any suggestions? Any UPS AT radio stack users have this
problem? How did you fix it? Should I run through the installation checkout
with the engine running so as to have more noise impinging on the microphone
while making adjustments? Don't like the idea of head down in the cockpit
with engine running but I can tie down the airplane while doing the checks
(I'm talking ground running here not trying to make adjustments in flight)!
Thanks for the help.

Do receiving stations (tower etc) hear the crackle on your transmissions? Is
the crackle only in your side tone. Do you hear the crackle on incoming

I have good news: I found the cause!
It turned out that the nav section's volume was not completely turned to silent.
The volume knob was just a fraction from being closed, so I was very surprised
that this fraction totally blocked the COM audio to my headset. Valuable lesson
learned.
What I would like to do next, is to find a way to minimize this effect. Any ideas?

Hi,
I just got my new Sonex #0037 but there`s a problem with the COMM system. It`s
installed a King Bendix KY97A COMM and a DRE-244E intercom.
The problem is that I cant transmit messages. At first I thought there was a wiring
failure after seeing the horrible wiring that had been done, so I decided
to take out all the wiring and start all over. I took the COMM and Intercom with
me home and started making a new wire harness from COMM-Intercom and new wires
to PTT`s, Headphone and Mic jacks. After to many hours with wiring and without
any form for pin outs and diagrams I thought I had figured it out. But still
the same problem accrued.
The only piece of diagrams I could find for the KY97A and the DRE-244E intercom
was this.

Not very useful but some. I went through all wires and connections but I couldn't
find anything wrong. I can hear my self on the headset talking on the intercom,
I have music input, the intercom volume and squelch works, I can receive
messages from my hand held radio, and when pushing the Pilot PTT I get a LED light
up on the intercom showing there is being transmitting a message. The TX
synbol on the KY97A also lights up. The hand held radio only receives some buzzing
noice and not any voice message.
Any one got any ideas ? I am also very thankful for all help and if anyone has
got some better diagrams for both COMM and Intercom.
Thanks ! :D

Just noticed the part where you say others in the pattern say you are
breaking up. This puts the problem squarely in your PTT circuit. Most
transmitters have a pin ground out to cause the transceiver to go into
transmit mode. In your case That ground is dirty or loose. Check your pin
out for the PTT and then check the appropriate circuitry.
BUT FIRST....
Before you go pulling everything out I would recommend trying a different
microphone if you are using one with the PTT on the mic or a different PTT
switch which you would use for headsets. Dollare will get you doughnuts the
problem is a dirty PTT switch.

I had a very similar problem. It turned out to be a poorly crimped pin on a
purchased harness. Try inspecting at all the related connectors and pins.
