Hello
Let me introduce myself: I'm french, I build a RV6, I finished dashboard and I'm trying to mount my avionics.
I team my RV6 with a GARMIN GTR 225 A radio, I get no audio panel (just one radio on board), I realize the audio connection and micro following Garmin D-13 installation manual,
At the initial operation, no audio, no return micro...! Total silence...!Oops
Power off then verification of the installation, I note that I reversed 'Tip' and 'Ring' connections on the jacks mic of the pilot and co-pilot...
Back into compliance.
During the second start-up I first connected my headphone audio jack (David Clark H10 - 13.4) side co-pilot: I hear the ads for a nearby airport IFR arrival but only when I cut the automatic squelch...! Same-side pilot.
In a second time I plug in the mic, I notice that the radio immediately enters transmit (TX displayed on the screen) without action on the PTT mode, no return micro audio and then after a few seconds a message appears onscreen: "COM PTT KEY IS STUCK.
I put out of service radio, then the put into service connected headset driver-side, same symptoms?
A third test is carried out without any connected headphone jack plug, then a pulse to the PTT on the radio screen appears then TX which disappears when the PTT is released. (Which seems to be normal!)
The same results are obtained with a second (different headset)?
No change when through the menu, I put the intercom on 'on' or 'off '...
I hope not have "on toasted it" during the first test!
My knowledge in this area are very "limited" If a soul charitable overseas can come to my aid... I would be grateful.
