I had the same problem one time and it was caused by a corroded connection
on my rotor cable.
Turn the radio up so you can hear it and start moving cables and tightening
connections.
That's how I found my problem.

Hi JIm
There is 1 on 1240 and 1 on 1340.  I am about 1 mile from the one on 1240 
and about 5 miles from 1340.  I still think it is something in my antenna 
somewhere because it is nil on the vertical.  73
