Hey guys-
I posted in the COMM section, but that place seems to be the nether region of the board, so I thought I'd throw it here..
Currently using a Narco MK12D+ with a Telex PT-300 as the PTT..
Lost my ability to transmit voice today.. Carrier was heard and I was still able to receive, but not transmit..
I thought the PT-300 might be the culprit.. Plugged it up in our Cessna and indeed it was not the PT-300..
I thought the boom mic of the headset I was using at the time might have died.. Tested it in the Cessna with the PT-300.. Works like a charm..
So, it is obvious the issue is within the RV..
My knowledge is exhausted at this point.. I simply do not know enough about how this stuff works to diagnose the issue any further..
Could the mic jack be dead and still allow the radio to transmit carrier? If the mic jack was dead, would the PT-300 function at all?
I checked the jack connections and there are no loose or frayed connections..
Just trying to get an idea of what to check before I submit the RV to the $65 an hour avionics shop..![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Thanks guys..
