Ok Nick, thanks for your comments so I now know that I'm not the only one with that annoying problem. It sure didn't impress anyone when I did a "Show and Tell" for some of the guys in our ham club yesterday when I took the K3 to a picnic get together. I sure hope that Elecraft takes this seriously as I would think that they've come across that before and should have a simple fix. Fern

I did some things to eliminate top cover resonances and then I began to notice this. It's a little more subtle than a continuous buzzing along with the tones of CW. Sort of a scratchy sound. I thought it was in the audio, but no, it's gone when I use headphones or an external speaker. I thought it might be an artifact of processing, but no, it's still there when I turn processing off. Band noise is enough to cause the sound on a moderately noisy band (not hard to find these days). Moderate (but not excessive) volume is required to being it in. I did note that as I crank up the Lo Cut, the noise disappears when I cross 250 or 300 Hz. Thus far, I've removed some of the things I did to dampen the top cover plate. I removed the top and looked for any loose screws and tapped various components for sound. Removed the bottom cover and attempted the same. No luck. I hate the thought of disassembling the entire front of the rig ... 73--Nick, WA5BDU Fern Rivard wrote: > I have a K3 serial #412 which has always had an annoying resonance from > the internals of the radio cabinet somewheres when using the internal > speaker.
