I have an electric interference problem that I hope someone might be able to shed some light on. I am constructing an RV 8 and have installed a Dynon FlightDEK 180, an ICOM 210 and a KT76 Transponder as well as a PSE intercom system. Tonight I was doing a radio check with everything on and at least have success in that everything appears to work. Here is my delema, when I press the push to talk button on either control stick the Manifold pressure reading on the Dynon starts to go up and the elevator trim indicator (Ray Allen) immediately indicates full nose down trim. When I power down the Dynon and again press the push to talk button the trim indicator remains at the neutral trim reading. Intercom on or off has no affect. If I leave Dynon on and turn radio off and push PTT button there is no affect.
None of these systems is interconnected and I have run all the communications using shielded wires.
Any suggestions on where to start looking? Oh, and on the radio transmissions the tower said all was 5 by 5.
