I agree about the way the sidetone volume is adjusted. When I go from headphones to speaker, I have to reduce sidetone volume to keep from blasting the entire house with my beeps. I have to remember to make the change BEFORE unplugging the phones otherwise I'm forced to push that MON button and emit that continuous tone while I crank down the volume. It would ok if it didn't make all that noise. I've never had another rig that forced you to listen to the spot tone just to adjust the sidetone level. Normally you would just turn a knob and be done with it. And yes, sidetone should track AF gain but that needs to be an option since some folks think sidetone volume should remain at a constant level. I can live with it either way. Anyway....my k3 is a lot older than yours AND I do not have the second receiver. Somehow I just bet'ya your thump has something to do with that extra receiver. I wonder if you can make a .wav file of that thump and I also wonder if the thump appears in the low level audio output on the back panel.
