I'm New Here
I need help on my RV-8. I have installed an FlightCom 403LSA intercom and two com radios, a Becker and flightcom. I am using switches (not an audio panel) to change which com radio to transmit on and monitor.
When I have one monitor switch off, the other radio works as expected. So if I transmit on com 1 and only monitor com 1, everything is great. Same with com 2.
The problem occurs when I have both monitor switches on, and can monitor both com radios. The signal from com 2 (the flightcom) is decreased. If I turn the radio volume way up, I can hear it, but this is not right. Do you have some suggestions as to what I can do to make the volume on both radios the same when monitoring both radios. I'm thinking I need a diode on the headphone lines so the signal from the radios do not go into the other radio.
Thanks for any help
