John:
I noticed the same thing and tried encapsulating the relay with that
material that's like Coax Seal. It quieted the relay completely, but I
noticed that when I ran in CW contests, after a few hours the relay would
stick for a second in the TX position, so I changed out the relay with a new
one from TT, but this time I left the leads on it an didn't press it all the
way down into the circuit board. I can still hear it, but it's not as loud
as when the radio was new.
Hope that helps!
