Do you still feel this might be the problem even if the
hum/buzzing is present even when the audio signal
is not plugged into the transmitter? When I turn the
transmitter on, the test radio just starts buzzing like
crazy. Plugging the audio source in does nothing, I can
get the audio to be heard in the test radio but not
loudly and certainly not clearly.
do you still feel it might be this ground loop?
