I managed to make the AF and Rf gain inoperatable
 and the frequency display slowly
increase continuously by itself.
I managed this by using Ham Radio Deluxe ver 4
I turned the slider on the computer program and the volume control
on the radio separately.

I could only  change the volume running the HRD program
the radio controls were inoperative.
I tried a parameter initialization   that fixed it but when I went to
do a system restore  the problems resumed.

Somehow while working in the Config menu but not changing anything
the problems fixed themselves.

Any ideas how to fix this problem if it occurs again.
Or what caused it

Thanks Richard
