Do not connect the two shunts in parallel. Doing that is the same as connecting
the two alternators in parallel. The Dynon would read the higher of the two
voltages, not the sum. Using a relay will work.

Just my two cents worth but it is important to understand that many regulated power
supplies and regulator ICs require a minimum load (current draw) before they
will regulate.
It is possible that the intercom does not draw enough current to do the job and
a load ohm resistor across the input power but after the on/off switch might
be required.
This load resistor is an important circuit element even with LM317 regulators.
They specify a Min Load Current of a few milliamps, but other supplies can be
several tens of milliamps or more.

I am building a Van's RV-12 that has a Dynon D-180 with a remote compass located
in the tail. The Van's supplied cable is not shielded. Instead, individual
wires are twisted together. Since shielding is optional, I would not be too
concerned about making a splice at the wing root. This application is not critical
like a coax carrying a radio frequency. Any type of connector should work,
like a D-Sub or even a 4 pin automotive trailer hitch connector. Since Dynon
uses a D-Sub on each end, that would be good choice for the splice.

I have an A210 and intend to use the intercom, but it's not yet functioning.
I have the wires installed, but I've not had a passenger lately, so
finishing it is a low priority right now.

Right on. I'll also suggest that unless the
relay is really desirable from the perspective
of reducing numbers of wires at the panel controls
you might consider using just a DPDT switch
as shown on the third page of:

Hmmmmm . . . What is the nature of the noise?
whine, rumble, static, does it's pitch or repetition
rate change with engine RPM. Does the noise go
away if EVERYTHING else is off while only the
radio/intercom pair is operating?

If the area is expected to stay DRY, then

Hi Mike,
FWIW, I'd encourage you to just put in the external intercom and be done
with it. The internal intercom of the 200's is barely what anyone would
call a functioning and usable intercom. I won't bore you with the details,
but suffice to say our experience has been that almost any intercom is many
times superior to the internal one for many reasons. BTW, the 200 is indeed
a great little radio, just not a very good intercom!
My 2 cents as usual..
Cheers,
Stein

Not related to the intercom but....
I put a A-200 in my experimental and can say it is a great unit. Clear, long

The one BIG drawback to it was the display is not easy to read unless I turn

WRONG.... The display is too dim for me to see in normal conditions, I don't

Hello List,
I'm getting very close to hooking up all the components to my instrument
panel,
and I'd sure like some advice regarding my Icom A200., to be put into the
2-place
plane I'm building.
I have a SoftComm International ATC-2 potable intercom that I got for my
plane
years ago. I also have a Icom A200 (mobile style). Basically, it the same
a the regular
A200, it's just that it comes more like a CB radio; attched mic via a coiled
cord, speaker
that pluds into a 3mm plug recepticle, hot/grnd leads for power.
Anyway, back to my question; For those guys that have experience with the
built-in
intercom function of the Icom radios, would you say that that alone is
sufficient (for a 2-place),
or is the intercom part "lacking", and in need of a separate dedicated
intercom?
Frankly, if the concensus is that the Icom is up to the task, I'd rather
just go ahead and
install a couple of jacks and be done with it. (the intercom part, I mean)
So, wuddaya think of the Icom intercom??

Is there a way of hooking up the Softcomm intercom with the Icom A200=2C

NOT be an open mic arrangement? I expect the cockpit noise will be "fairly

I thought about the using the switch directly and may still do that. Using
the relay tied to the switch for the auxiliary alternator set it up so the
shunt selection would occur when the auxiliary alternator was turned on,
eliminating the need to toggle two switches.

Right on. I'll also suggest that unless the
relay is really desirable from the perspective
of reducing numbers of wires at the panel controls
you might consider using just a DPDT switch
as shown on the third page of:

Hi Mike,
I didn't catch what kind of plane? If it's an RV or similar the standard
softcomm wired as per the manual will be just fine. No need for separate
"Push to Intercom" switches. Honestly I'd avoid them anyway. With the
exception of a very few warbirds and the occasional helicopter, we've rarely
seen the need for those to be installed. It's actually not fun to use one of
those systems, it's akin to using a walkie talkie and trying to have a
conversation....
My 2 cents as usual!
Cheers,

Thanks. That does it, then. I'll just go with my Softcomm intercom.
Maybe I might need a pointer or two hooking it up. I'm hoping I can get
it working, but .......
Is there a way of hooking up the Softcomm intercom with the Icom A200, and
NOT be an open mic arrangement? I expect the cockpit noise will be "fairly
high", and it is my understanding that if each person pushed a button
everytime
they wanted to say something, it would be much less annoying.
Or is it not worth it to hook up the PTT design, and simply adjust the
squelch

Hi Mike,
FWIW, I'd encourage you to just put in the external intercom and be done
with it. The internal intercom of the 200's is barely what anyone would
call a functioning and usable intercom. I won't bore you with the details,
but suffice to say our experience has been that almost any intercom is many
times superior to the internal one for many reasons. BTW, the 200 is indeed
a great little radio, just not a very good intercom!
My 2 cents as usual..

| Subject: | Re: Intercom Noise |
Trouble shooting electronic gremlins requires a systematic approach. The
most important thing to remember is to only change one variable at a
time.
If you have swapped headsets and the noise remained, we can rule out bad
headsets.
I would suggest the following decision tree.
1) Test the intercom in another aircraft if possible. If the problem
follows the intercom, the intercom is bad.
2) Test with the engine and ALL other electrical devices OFF except
the intercom. If no noise proceed to 3
3) Repeat 2 with engine running and ALT off.
4) Repeat 2 with engine and ALT on.
5) With engine off, turn on separately each other piece of
electronics.
6) Repeat 5 with engine and ALT on.
Get back to me with the results.
Are you using shielded wire? Is the shield only grounded at one end
(which is correct)?

Bob,
More data points:
I installed a portable intercom in my plane. Its plugged in the new
Pilot mic & phone jacks. With only the internal 9v battery powering the
unit, I still get the noise in my headsets, but it is tolerable.
Intercom off = no noise. When I power the portable intercom from ships
power the noise is louder, but still tolerable...barely.
Any ideas now?

| Subject: | Spiral Wrapped Panel Wire Bundle |
Hello!
I've changed the supporting structure for my instrument panel and subpanel for
my Sonex and would like to get some feedback on my ideas for securing the wiring.
The main panel is tilted per plans at 30 degrees and is attached via piano on top
to the glareshield with a piano hinge, on the sides with nutplates, and to
the subpanel with another piano hinge. The subpanel is from a 1/8" thick extruded
angle, which is 1.5" tall and 5/8" deep.
Pic 004 is the only one taken with the panel in the closed position. The others
are with it tilted partially open for viewing. One concern is getting the wires
going to the back of the MGL Enigma EFIS so they aren't dangling down onto
the control cables. Looking at pic 006 you can see two white wires going into
the left side of the EFIS. I'll move these (as well as a blue wire not shown)
into the spiral wrap so they will exit the bundle to the left of the EFIS, about
where the grey cable exits. This leaves only the wires going into the 9 pin
connector. It came delivered with these wires looped around through the ferrite
tube as shown. Orange and green for OAT will go to the red and green wires
coming out of the wrap on the right. White won't be connected to anything. This
leaves the black ground and red supply wires. I didn't make the black ground
long enough, so I'll resplice it. This will allow enough slack to move the ferrite
tube to a better place instead of dangling close to the control cables,
and more importantly, the center flap and brake handles.
So I'm wondering where a good place for this ferrite tube would be. If it needs
to be secured, I could strap it on top of the 9 pin connector with a couple tie
wraps around the outside of the tube. Or turn the tube 90 and run it through
the middle.

| Subject: | Re: Spiral Wrapped Panel Wire Bundle |
Another issue is securing the spiral wrapped bundle to the subpanel. I had thought
of simply drilling holes every 6" through the top of the subpanel and cinching
the bundle down with tie wraps. You can see a couple of temporary safety
wire pieces twisted in place in the pics. But instead of doing this, I thought
it would be better to support the bundle with those saddle anchors that can be
riveted on.
The final issue I have is where the spiral wrap drops below the top of the subpanel
on the cabin's left side (right side in pics) and goes between a switch cover
and the vertical face of the subpanel. I can't have it continue on top because
the light with a red and black wire would interfere with it. I figure I
could wrap this area with silicon tape to protect it against the edge of the subpanel.
Or maybe adding another section of spiral wrap over the existing spiral
wrap, making two layers of it.

| Subject: | Icom A210/A200 owners |
Hi Stein=2C
I'm building a Kolb MkIII. My engine is a GEO Metro (yeah=2C from the ca
r)1.0 liter=2C with a turbo
and muffler. Because of my exhaust system=2C I expect my engine/prop will
be more quieter than
most of the other MkIII's=2C but that's only conjecture=2C at this point.
Hopefully=2C I should know in about
a month.
I was building an RV7A=2C but sold it to buy my GlaStar kit=2C which is o
n the back burner until
the Kolb is done. I need "something" to fly!!
To make matters a little screwed up=2C I have a Icom A200 mobile version.
This is more like
a CB radio=2C in that everything is already attached (mic=2C spkr=2C tray
=2C etc=2C etc) for an underdash mount.
This isn't much of a big deal=2C just different.
I threw away the bracket=2C and mounted the tray into my panel=2C just li
ke any other Icom A200 built-in.
(Now=2C nobody will know my secret)
Compound the Icom A200M with the fact I have a portable Softcomm Int'l AT
C-2 intercom.
There aren't any small colored wires=2C exactly=2C just two cords....one th
at is a pilot/co-pilot microphone combo
plug=2C and a single headphone plug. (the colored wires are inside of the
large black cords)
These two plugs would plug into a typical mic/headphone system. Somehow
=2C a guy would need to
incorporate a PTT switch=2C but I haven't figured that part out=2C yet.
The Softcomm intercom has two large wires(looks like AC cord a toaster wo
uld use)=3B the first one
(microphone) has 4 wires inside of it=3B
1) white....which goes to the mic#1 tip
2) blue......which goes to the mic#2 tip
3) red.......which goes to the center section of both mic #1 & mic# 2
4) black....which goes to the base of both plugs
The other large plug wire (for headphones) has two wires inside of it. A
red one and a white one.
I haven't identified which one goes where=2C but it's easy since I can get
to the circuit board and
chase them with a multimeter out to the plug.
From what I can tell=2C it doesn't look too tough to draw up a wiring sch
ematic and get it done.
Thanks for everyone's help.
I attached a picture of my project. It is MUCH further along=2C and is a
lmost finished=2C just no recent
decent pictures.

Subject: AeroElectric-List: Icom A210/A200 owners
Hello List=2C
I'm getting very close to hooking up all the components to my instrument
panel=2C
and I'd sure like some advice regarding my Icom A200.=2C to be put into the
2-place
plane I'm building.
I have a SoftComm International ATC-2 potable intercom that I got for my
plane
years ago. I also have a Icom A200 (mobile style). Basically=2C it the sa
me a the regular
A200=2C it's just that it comes more like a CB radio=3B attched mic via a c
oiled cord=2C speaker
that pluds into a 3mm plug recepticle=2C hot/grnd leads for power.
Anyway=2C back to my question=3B For those guys that have experience wit
h the built-in
intercom function of the Icom radios=2C would you say that that alone is su
fficient (for a 2-place)=2C
or is the intercom part "lacking"=2C and in need of a separate dedicated in
tercom?
Frankly=2C if the concensus is that the Icom is up to the task=2C I'd rat
her just go ahead and
install a couple of jacks and be done with it. (the intercom part=2C I mean
)
So=2C wuddaya think of the Icom intercom??

John;
The drawing is a little small to see the detail clearly but....
Yes, I think you've got it. (you've depicted a four pole switch, one pole of
which you aren't using which is fine.)
You need a second wire to your load meter from the upper pole of the switch
to complete the shunt circuit.
The progressive transfer feature which I think you've depicted on the upper
two poles isn't needed.
The switch need be only two position double throw, without a centre off
position which it appears you've drawn.
But yes, this is basically correct without nitpicking the drawing details
which are waaay superior to anything I could come up with.:-):-):-)

Pull alt cb and no noise. No different with any radio configuration. I
also get noise occasionally from the electric motors of the flaps and
fuel pump when they are run. When I use the portable (9v) intercom the
noise is less, but still there. When I use ships power, the noise is a
little worse, but much less than the installed Sigtronics intercom. When
I use no intercom at all I can barely hear any noise, but it is still

| Subject: | SD20 and LS-1A 'net' available power |
Bob,
I am doing some system load planning/balancing for a Z14 dual bat/dual bus
type setup. I have 28V SD20 and LS-1A as Alt#2. For the sake of
discussion, assume the alternator is turning 3500 rpm and generating 20amps
of current (per spec).
How much of this current/power would typically be re-consumed to drive the
regulator/alternator field at max 20 amp load (i.e. what is the available
"net" power)?
I know the std/recommended LS-1A setup has a 2A breaker on the sensing lead
and a 5A breaker on the field lead, but I'm guessing it actually consumes
less than 7 amps of it's 20 amp output (or is that already 'netted out' of
the 20 amp spec).

Then the problem is an ALT diode or a wiring ground/shield error.
The easiest to check is the ALT. Pull it and send it to your favorite

Can both alternates feed continuously into the main bus and battery ?
