I was operating in the TN QSO party on 80m last night in Diversity mode with headphones on. I'm not sure what I did but I got a huge continuous blast in my right headphone. I couldn't get the headset off fast enough. I did a power on reset and it cleared. I don't remember if I pushed NR or not. The blast not only blew my right eardrum but blew any memory I had of what I was doing at that moment. I do mean Ouch!

Firmware 3.30 -- using NR (3-4) on SSB (14.178), first the volume control did not work then after a little while the K3 goes to full volume and only turning it off gets rid of the problem. THIS IS A SERIOUS PROBLEM!!! Hearing loss could result. Please got on this ASAP. 73 de W6BK On Aug 30, 2009, at 10:08 PM, Eric Swartz -WA6HHQ, Elecraft wrote: > Lyle just figured this out and corrected a typo in the dsp code.
