TS-940 strange problem
 

My TS-940 goes to a state of very little gain. For instance the noise
level on 40 meters drops and the received signals are low in
amplitude. If I make a noise click with my rotator, (just push the
brake lever button so I create a noise spike) the receiver gain
immediately comes back up. What in the world could be causing this?
