When I turned everything on I got bad redio interference on 123.3,
123.5 and 122.8. Just about drove me nuts looking for the source,
turned both GPS's off.........no change, turned the SN-10 off and the
interference went away. Started grounding things and moving wires and
then I thought, what has changed? The USB adaptoter was added, so I
plugged in a stick and the interference got worse! I had located the
USB adapter within an inch of the radio antenna cable (RGU-58) where
it exited the instrument panel.....................moved it away and
the interference went away!
Recommend you place the USB adapter a good 4" away from rour radio
antenna cable.
Cheers,
