Radio
Been having problems with Com radio. Works fine, take off fly for an hour, lately half the time I return to airport tower says the only thing they hear is a carrier signal or a broken signal. After I park, I play with connections call ground and everything is fine. I have Garmin PTT switch and Flight com intercom, Narco 12 D radio. Can anyone give me best way to troubleshoot problem.
Thanks
