Hi Mike
I have the Garmin SL-40 with the built in intercom and it worked flawlessly
to Osh and back. Can set mike levels seperately which I understand is
something u can't do with the Icom. Second plane in company with us has a
Icom and pilot said he'd not get another.

Is anybody here using the built in intercom feature of an Icom A200?

Thanks Steve, I'm thinking about buying a C-150, and it has an Icom in it...
but hooked up to the overhead speaker and hand mic. I worked on jets for to
many years in the Marines, I need a headset... so I was hoping somebody with
experience could tell me if built in intercom on the Icom is decent, then I
wouldn't have to buy an intercom.

G'day Mike

I have the Icom A200 in my Rebel and it works flawlessly, and I use the
inbuilt intercom system.
The intercom system is a great feature and it does away with unnecessary
external systems. (Listening to music while I fly is just a distraction as
far as I am concerned!)

There are more than 90 planes at our field, and the Icom is by far the
preferred choice. That must say something!

I have combined my Icom with a set of Sennheiser noise reductions headsets
and it is one of the best investments that I have made. All those extraneous
noises just go away! With the Sennheisers the microphone outputs are
individually adjustable and of course the volume.

regards

Ian Donaldson

I know some guys have used it but I believe it is a push to talk type of
intercom. Leastwise I don't see any way to wire a VOX squelch adjustment
on my icom.

FWIW the hot mic with noise cancelling on my flightech intercom works
very well regardless of mic gain settings. I like it better than the VOX
type intercoms that I've used.

I don't understand why one would one want separate mic gain adjustments
on a radio? I'm slowly matching mic gains on the headsets so that all
headsets are interchangeable. The factory mic gain setting on my icom
was set way too high when I purchased it.

You don't have to buy an intercom either way. I've got a FlightCom 2-place
with extension box for two more that I won't be using.

Thanks Mike, that's definately an option, but I'll probably talk to Aircom
first about using the Icom... I've got to have at least one set of jacks
installed anyway since there aren't any.

This is the impression I got from the information on Icom's web site... but
it really wasn't clear. That's why I asked here, I figured somebody would
be able to explain it. I'd prefer a VOX type setup, but could certainly
live with the push to talk... I'll probably spend most of my time in this
airplane solo anyway.

Thanks Ian, can you verify whether this is a push to talk intercom? Their
web site really doesn't say anything, but I found a review that talked about
an operate/intercom switch.

The more common method is to wire the mics to the intercom connection on the
A200, such that he intercom is normally connected. Then, when PTT is
pressed, wire it such that the pilot's mic is switched from the intercom
connection to the coms connection.and if you like, simultaneously ground the
co-pilot mic. Best done with a DPDT relay but I have done two with a DPDT
push switch in the stick. Makes for a difficult job getting all the wires
run up through the stick. A relay, mounted remotely but triggered from the
PTT button in the stick, is a far better approach.

All that said and while it certainly works, it does mean the intercom is
'hot mic", or always on unless the PTT is pushed, rather than using a vox
switch. I have installed 5 of these radios that way but let me say, I think
a separate intercom is the way to go and that is what I am doing on my
aircraft.

It needs to be said that the wiring info on this aspect in the owner's
manual is not particulary useful and in the service manual it is no better.
It has led one common Australian aircraft, the Lightwing, to appear with a
separate toggle switches to control the radio/intercom operation, as well as
the PTT button. I dont know whether it was the factory approach or that of a
particular installer but I think it is a very clumsy approach. However, I
think they were led there by the diagram in the owner's manual.
