Distortion

Distorted audio can be caused by one of two situations. The first and
most common is improper adjustment of audio levels. Be sure you’ve
adjusted the radio(s) volume controls as recommended in this manual.

RF in the shack can also cause distorted audio. To determine whether
this is the problem, connect your transmitter to a dummy load. If the
distortion disappears, then you have RF floating around the shack. To
eliminate RF problems, first make sure you have set up the jumpers and
radio cables correctly. Then check that you have a good ground between
all pieces of equipment and that your RF ground is low impedance. Refer
to any reliable Amateur Radio publication for detailed information on RF
problems and RF grounding.
