the sound goes away.
The radio is still hot right?
So, next step would be to open the covers and check to see that all grounds  
to each board are solid.
You will find coax connectors on the boards.
Reseat them.
Also make tight all board screws to ground.
Just un torque them a bit and make them tight again.
Remove and re seat all the molex connectors on all the boards.
Now, if that does not work you might try poking around the boards with a  
wood stick and see if you can make the noise go away or show up.
If none of that works you will have to scope the rig while it is making the  
You can then isolate the problem.
