Update
I thought I would let folks know that things are progressing well. They are just not too exciting at this point.
* disclaimer - this post is not directly related to the engine project so if you are only interested in the Honda - you are welcome to stop reading.
I did get my radio stack wiring done. This was something I started, literally, a decade ago. My stack includes COMM: Icom A200. Transponder: GTX320a, Intercom: Flightcom 403MC: a stereo and a 2 meter ham radio.
The good news is that the GTX320A is going to be compatible with the EchoUAT that I am about ready to purchase for my ADSB out obligation.
Gosh, it would be nice if companies used the same terms for the same wire! Some call the secondary line of a mic a "return" while others call it "mic Lo". UGH!'
Now that it is done. (Al be it still on my bench). I am very happy with the set up. I am impressed with the Flightcom 403MC. It small, and inexpensive, works great and had the Pilot Isolate and "All" switch. It is not stereo, which would be nice, but with all the engine, wind, noise I really do not see the need for it. I will rarely listen to it. ALSO, I learned a real neat trick to combine Stereo in to a mono circuit by only having to add a 500-100 ohm resistor on each channel to make it work. No need to spend lots of money for magic boxes to get this done. I have to fade it L or R to get the sound but I am quite impressed with the quality of the music.
I'll be pulling the panel out of the plane to install the stack and I probably will finish up the Pitot system while I am in there. I'll do the brake lines while I am there too.
As always, questions, comments, suggestions, always welcome.
