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?

Maybe a dirty relay, or an antenna,switch, or coax connector hanging
by a thread?..If narrowed down to the radio, I'd look at the relays
first. I don't know if they are cleanable or not..Depends on access,
etc to the contacts. See if maybe you can run a thin strip of typing
paper across the closed contacts if it's possible. MK
