So do I Fern. I tried the tape, which originally seem to stop the problem.
I then took a side cover off, and looked at the various clearances. I came to the conclusion the main culprit was the top of the PA shield being close to the top cover, but not actually attached to it. My solution, until I get the file out was to split a piece of rubber sleeving lengthwise, and curl this over the top edge of the metal shield. This forces the top cover up slightly and also stops the metal surfaces from coming into contact on audio peaks. 73 Stewart G3RXQ On Mon, 11 Aug 2008 08:34:25 -0600, Fern Rivard wrote: > Yes Stewart, I DO have the stiffener in place otherwise there would be some exposed > holes on the top lid!
