I've got a MAC1700 modified King KX170B. It recently started having issues with transmitting. It receives fine, but apparently in transmitting it just transmits hash, that you can barely make out a voice in it. I pulled it and replaced it with a known good KX170B, and that works fine in that tray, which eliminates the audio panel/wiring/antenna and pretty much leaves me with the radio itself as the issue.

Does anyone have a good avionics shop they can recommend for a test and repair of this radio?

Thanks.........
