Hi Everyone,
I had an issue surface today with my intercom / radio and I am trying to figure out what the likely issue is.
My RV6A has a FlightCom 403 with digital clearance recorder for intercom, and a KX125 radio. Push to talk on pilot side only.
The intercom system and radio have been working in my new to me plane, but today I could not use the intercom / radio with the following symptoms:
1) Plugged headset into pilot side headset jack:
1.a) when I spoke into headset without keying the mic, I could not hear myself.
1.b) when I keyed the mic button on the pilot stick, I could not hear myself on the intercom, and ground did not seem to hear anything ... l got no response.
2) Plugged headset into copilot headset jack:
2.a) when I spoke into the headset without keying the mic, the intercom seemed to work because I could hear myself
2.b) when I keyed the mic button on the pilot stick (with headset in copilot plugs), I could hear myself on the intercom and the ground controller said "aircraft calling ground, all I hear is static"
3) Tried steps 1 and 2 with different headset make/model with same results.
4) Removed the female microphone plug jacks from the panel on each side (so they are dangling without touching panel).
5) Removed and reinstalled kx125 radio from slide in mount ("re racked").
6) Current state: Intercom seems to work now for both sets of headset plugs. Radio can receive ok. No transmit possible / push to talk does not seem to do anything / no "key up" noise when pressing push to talk button.
Any ideas on where I should focus my troubleshooting efforts? The pilot side headset jack? Push to talk button?
Thanks
