[Elecraft] K3 Speaker cabinet resonances

[Deni F5VJC]

Thanks to all who responded to this question.

Having looked into it further it seems I have a combination of cabinet buzz
and a defective speaker.
 I removed the top panel of my K3 did tests and found the most bothersome
buzz at 600/610 Hz is still present with the top panel detached.
Checked screws all tight (not too tight) and various other mechanical tweaks
but can't clear it. So I guess I will email Elecraft support about a
possible replacement speaker.

This is a very small annoyance in an otherwise fine radio, and it's just
come to light now because I always used external speakers or headphones
until now, having reduced my K3 to bare bones due to an impending move of
shack, I'm listening to it's internal speaker.
