Is it possible that low voltage/ weak battery could be the contributing to the problem? I charged up my battery and started trying things again. It seems to be working fine now.

I tried that yesterday. No change. I also swapped out the coax runs. I only had one cable so I tried each side independently. No change. The antennaes are installed with star washers and I checked for good contact. I double checked the isolation of the jacks from the airframe. I did find that...

I've installed two coms and I'm testing them in my garage. RV7 with two delta pop aviation antennas mounted on the belly. Dynon intercom. Harness built according to the manual. RG400 coax. When I transmit on com 1 it breaks the squelch on com 2. Different frequencies. Same vice versa. I have to...

Thanks for getting back to me so quickly. Maybe you can clarify one more thing concerning the mic jack wiring. PTT switch wire from my grip to Intercom Pin 10(Pilot Mic PTT) Jack Tip(PTT) not connected Jack Ring(mic audio) to Intercom Pin 23 (Pilot Mic) Jack sleeve(common) to Intercom Pin 2...

One for the hat switch(trim) and one for the rest of the switches(PTT,CWS,Flaps,Com flip,smoke). I combined...

I did not say that clearly. When I said the ptt switch I was actually referring to the switch that would control which com you transmit on. The actual ptt switch would of course be on the grip.

I'm curious what others with two coms have done for switching between the two. I plan on using tosten military grips and just asked him if he offers a spdt switch to control the ptt between the two. His website shows a momentary switch. Do you turn down the volume on the other com you are not...

In an effort to reduce wiring to the back of the plane is it possible to have the transponder and adsb use the same power run?

Hello, I’m getting setup wiring and have come up with some questions. I’m building an RV7. VPX Sport 2 – Dynon SV-D1000T 1 – Battery Backup 1 – Adahrs mounted aft of baggage area on shelf 1 – Engine Module 2 – Dynon Comm Radios 1 – Dynon Intercom 1 – Dynon Trasnpoder mounted aft of baggage area...
