[Elecraft] Re: [K3] annoying resonance with internal speaker in K3
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!

Yes Stewart, I DO have the stiffener in place otherwise there would be some exposed holes on the top lid! I temporarily put some black electrical tap between the contact areas where the top lid meets the radio but that didn't stop any of it. The resonance appears to come from down below the pa unit.

Strange, mine not only does not do that, but I can't make it do that even if I tap it - do you have the chassis stiffener in place correctly? -- In theory, there is no difference between theory and practice, but in practice there is.

There should be a greater clearance between the two. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
