We have a Europa XS and have a Archer antenna up in the top of the rudder.
We are thinking it would be nice to have a Vertex Nav/com handheld not only for
back up,
but to use as a second radio.
Any suggestions what type of antenna could be used on the inside, and location
that
would work reasonable for Comm. and VOR? Traditional for Europa is to put a copper
foil
inside the sternpost, but i think that would be too close to the Archer?
Second question, what intercom would allow us to hook both our Becker panel transceiver
and the handheld?
Thx.

Ummm No not according to the last time this was discussed six months or
so ago??
I don't remember the terms but the conclusion was that most modern PM
regulators did not draw rated power from the engine and dump the excess
as heat in the regulator. The size and cooling area of my John Deere
regulator is way too small for that. As a result I haven't provided a
drip tray to collect the molten aluminum or arranged to keep the PM
alternator heavily loaded.
I assume the regulator is switching short pulses of current to control
the voltage and that is also why a large capacitor is helpful if the
unit is not continuously connected to a battery.

The OV Protection for Built-In Regulator drawing shows that a 60AMP alternator
gets a 4AWG and a 80AMP current limiter. With this setup do I need 4AWG wires
going to my Battery Bus and Main Bus or is 8AWG sufficient?
Next question my current sensor has a hole that the 4AWG wire from the OV contactor
to 80AMP current limiter needs to run thru. I'm not sure a 4AWG wire is going
to fit thru the hole (I don't have it yet). Can smaller wire be used here,
if needed?

If you're a professional designer of terminals and the tools that install
them, you would do well to at least KNOW what the optimum die shapes
and pressures are for installing ANY terminal on ANY wire.
You would be equally aware of a RANGE of acceptable installations
selected such that one tool does an adequate job installing several
terminals on several wires. This allows one tool to install a red
PIDG on 18, 20, and 22 AWG wire.
>(2)What particular CSA (Canadian Standards Association) standard says that
>the answer to the previous question is yes (at least in the Canadians
>minds) and why do they say so?
One can only guess. Without reading a report wherein terminals
were installed, data gathered and and a judgement applied as
to the adequacy of any particular wire/terminal/tool combination,
we're not going to know.
The poor man's rule of thumb is described in
http://www.aeroelectric.com/articles/terminal.pdf
as the "milk-jug" test. One could also repeat the
experiment described in
http://www.aeroelectric.com/articles/CrimpTools/crimptools.html
Check out the cross-section of a finished crimp
as illustrated in:
http://www.aeroelectric.com/articles/CrimpTools/GL.jpg
An inexpensive 30x illuminated microscope from Radio
Shack will let you do similar studies with ease.
It would be interesting to hear what a professional
from AMP/Waldom/TB has to say . . . Just be aware
that there are OPTIMUM combinations and ACCEPTABLE
combinations that cover a RANGE of situations. So
while getting their opinions, be sure to ask
their recommendations for home workshop testing
techniques that would help you explore compatibility
of your own combinations of terminals/tools/wire.

--> AeroElectric-List message posted by: "Dan Checkoway" <dan@rvproject.com>
Been using cabin heat lately. I'm not a big fan of the el cheapo CO
detectors that expire...I'd like to install a permanent, ship-powered CO
monitor, and I'd like it to have "relay" capability so I can remote mount it
and it can trigger a voice warning on my ACS2002.
I saw the CO Guardian products, such as the remote mounted 352R
(http://checkoway.com/url/?s=62876da4) do this, but at $369 it's a little
too pricey.
Does anybody know of a product that will serve the purpose -- DC powered CO
monitoring with a warning circuit relay -- but doesn't cost as much? Any
electrical engineer types know of a homebrew method?

Hi Dan,
Very interesting that this topic should come up I have been thinking the same
thing!
I was looking at the COSTAR Personal (P-1) Carbon Monoxide Alarm (http://www.safehomeproducts.com/SHP/SM/Costar_Carbon_Monoxide_Alarms.asp#9M). However; I have no ability (without doing some research) to know whether this is good or not. I figured I could tap into it's guts for a panel mounted light/alarm.
I too would like to build one versus buy.
BTW: Love you site - visit it often. Still waiting for an update on the iButton
stuff! :-)

Thank you, Brian,
Emboldened by the tacit support of one man in thousands, and
aware of (a) being off-topic mainly, and (b) there seem to be a lot of
unfounded suppositions regarding AoAs and landing, I dare to pontificate one
more time - nor is this a lecture, but barebones experience.
The purpose of the 'circuit' in WW I was to keep the stoogent in sight while
he fought to complete a landing without dying. This meant staying within
gliding distance while the castor oil leaked out. It has become a
cross-country because most don't know why it's there.
When landing within smallarms fire of the enemy, it is best to
do what Brian was doing - landing in no more than 30 seconds while never
holding the same heading for a split second and with one rudder pedal fully
forward (the outer one) to fool the sniper.
The result is the fighter break - fast pass to the button, pull
up and fan out as you bleed off the speed, pop the dive brake and extend the
gear in one short swell foop. You are diving down dirty in a circle, each
man changing runway sides to foil the bad guys and avoid the previous drag
turbulence.
This was all accomplished with an regularly-inaccurate airspeed
indicator. If there was an 'inside' wind to the circle everyone drifted too
close to the centreline and only occasionally the guy ahead would pull too
hard to make the runway line. That's when Mother nature got vexed and his
inner wing stalled, or else he went too vertical a roll and down she went.
This means landing through smoke and debris and reduced moral.
The answer my friends is sitting in the wind - the Angle of
attack tower - a vertical line of colours which go from green to yellow to
red to prang - or - stay green/yellow and achieve a landing. This device
saves aero bats and odd lawndart driver every day. It also finds specific
angles which ensure accurate endurance speeds, best lift/drag angles, and
similar specialty numbers.
I have no financial interest in a particular design, but you may
be sure I (and others) won't be looking down at a needle. I'm not much at
numbers but I know my basic colours.
I'll shut up now.
Cheers, Ferg

Dan,
Kinda like this one http://www.s-tech.ca/products/ps/ps001.htm It's a
little large and intended for residential use so it's not tested in an
aircraft environment. Don't know if altitude, pressure temp makes a
difference. The good part is it runs on 12VDC, consumes only 5 watts and
has a dry contact output to interface to what-have-you, and has an LCD
display to display readings between 15 and 500ppm, and a recall function to
recall the last high reading. May be worth looking into.
Thank for also documenting your cross country trip and maintenance
experience.

OK, Googled 'co detector'; here are some standalone units:
http://www.globalsources.com/manufacturers/Carbon-Monoxide-Detector.html
(didn't notice any prices)
Also, just took the back off our 120 V AC 'white label' model CFCOD CO
detector. There's an internal board mounted transformer feeding a pair
of diodes, feeding a 7805 linear regulator. If you can run a soldering
iron you can probably convert one to 12 V use.
Is that enough info to get you going, or do you need more details? A
device in hand & a phone will probably work better from this point forward.
Email me direct with your # or I'll send you mine.

They do look like nice units...and almost what we may be looking
for...except, on reading the specs for them, they specify not installing
them where the temperature may get below 40 or above 100 degrees F.
Kinda lets out aircraft use...unless exceeding that range limit only
produce a slight change in sensor accuracy, and no permanent damage, or
a need to recalibrate.

Hi All,
I'm planning on running split corrugated nylon conduit between my wing ribs.
I also plan on having an autopilot servo and heated pitot installed.
I was wondering if I should be taking any special precautions w/ regards to how
the wiring will be exiting mid-way from the conduit for these accessories?
Or should I have seperate wire runs for these items?
Thanks,

I used separate wire runs. I used conduit for the lighting runs to the wing
tips and snap bushings for the servo and heated pitot. I also used a right
side mount for the ap servo and this made the wiring a little less crowded
in the left wing. Don

If you want to home brew one from scratch I think you will find that
many of them use a Figaro sensor that runs on regulated 5vdc. (Might be
8 volts - it has been awhile since I played with them). The sensor is
not difficult to get and used to run about $15. There have been a few
projects in electronics magazines over the years so a search on "Figaro"
should turn up something. Get the sensor optimised for CO as they also
come optimised for natural gas etc. Shouldn't cost more than another
$10. in parts. It will be easy to make an overly sensitive unit but a
3914 chip and a 10 segment bar graph display is fairly easy to do.

Hi all
I did a search of Digikey & Mouser with out any luck. Any suggestions for a
supplier ?

Thanks Don - I hadn't considered wiring the AP on the right to simplify wiring.

Thanks for the Figaro pointer. I found the figarosensor.com web site, and
was checking this out:
http://www.figarosensor.com/products/2442pdf.pdf
I'm in so over my head... I can hook up wires, and I understand Ohm's law,
voltage dropping resistors, and that's about the extent of my usefulness.
Being able to create and synchronize voltage pulses 5ms @ 5.0V and 14ms @
4.8V...way beyond my capability! Shoulda been an EE instead of a software
guy, I guess. ;-)
If anybody happens to whip up a homebrew circuit that a newbie can't go
wrong with, much appreciated. And if not, no sweat...I'll probably just pay
the $49 for a 9V battery powered dealie, if at all.
I sent an email to the guys at Advanced Control Systems seeing if they
thought an onboard CO monitor for the ACS2002 was a decent idea. I'd pay
for it.
Thanks for the advice everybody,

The above sensor requires the the heating element and the excitation
circuit be pulsed.
Its going to take a little more logic to get things working if you want to
have a constant display. (a pair of 555s and a latching buffer for
starters)

Things have progressed. The one I had played with was TGS812 which was
simpler to use but probably obsolete now. Might be worth checking to see
if any of the current parts (for other gases) with a constant voltage
heater are sensitive enough with CO. I think you don't want it overly
sensitive for this application anyway and you are going to have some
hydrocarbons present as well as CO if there is a problem.

The circuit for driving the sensor is relatively simple for us EEs. The
real problem is that a specific sensor has such a wide range of
characteristics that the final device would have to be calibrated. I
don't know about you, but I do not have a calibrated source of 100 ppm CO.
Your best bet would be to buy one of the $50 units and put the guts in
whatever package you want. Adding a relay driver of some sort to drive
an external annunciator would be relatively easy since they already turn
on a noisemaker when the unit alarms. Plus they already have a readout
that you could mount on the panel.
