Hi everyone,
While testing out my new PTT button installation today, I noticed that my trim indicators freak out when I transmit. The one illuminated LED goes out and a few others come on dimly. Anyone seen that before?
These are the stock LED trim indicators that come with the aileron and elevator servos from Van's. Radio is a Garmin 430 and all coax is RG-400 with no splices or any other funny business. The trim wires do share a short run with the antenna line -- was I expecting too much of the RG-400 shielding?
I guess the trim indicators going out isn't too bad since transmitting is short and infrequent...I am a little more concerned about other systems though (like the Lightspeed.) I wonder if I have a bad RF leak somewhere?
Any thoughts appreciated,
Paul
