I have an early RV-12 with Gamin SL40 and Flightcom 403M. Intercom works well with both headsets plugged in. Comm transmits will with either headset as long as plugged into pilot side. Neither headset transmits from copilot side even though copilot mike works excellent for intercom. I have SL40 set to transmit with both mic1 and mic2. I also have both mic1 Level and mic2 Level set the same at 150 value. I?m stumped why intercom works so well with both headsets plugged in and yet I can?t Tx with headset on copilot side of plane.
I have looked at wiring diagram and see each mic comes into the SL40 individually so maybe pin for mic2 isn?t making good connection?
Thanks in advance?
