K3 huge noise
Locked
 
|
Almost lost my hearing.
Loaded 3.27A. NR engaged. F1-1. VFO A CW on 40m. VFO B SSB 40m. AGC ON. Width 250Hz cw. 2.7 ssb. Now switched from CW to SSB portion of 40m by pushing A/B - horrible noise of very high amplitude on speaker or headphones. Turned down the volume to min. and in few few seconds it stopped. Than again the same thing happened 70% of the time. This only happens if NR is engaged on A and B VFO and while switching from A to B. Just did it again-now on the internal speaker. Wow!! it is loud. Will not use NR for now. Anybody else can duplicate this?? Beside that I like my new K3 a lot. This is my second K3.

Lyle just figured this out and corrected a typo in the dsp code. We
should have a new beta shortly - Hopefully before end of Monday. (This is why we release beta test versions. ;-) 73, Eric mark roz wrote: > Almost lost my hearing. > Loaded 3.27A. NR engaged. F1-1.

Is this just a bug fix or are we going to possibly be seeing the
extended bass response and additional NR from long ago all wrapped up? ~Brett (KC7OTG) On Sun, 2009-08-30 at 22:08 -0700, Eric Swartz -WA6HHQ, Elecraft wrote: > Lyle just figured this out and corrected a typo in the dsp code.

Lyle hasn't got it yet!!
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.

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!
