Gary, Perhaps you are correct, but my serial number is not much younger than yours, only 200 or so, the only way I can get adequate volume from my K3 when the shack is noisy is to shut of the AGC, but that can be a two edged sword. I can turn the volume all the way up and the depending on what I am listening to it most often isn't too loud. (I'm not hard of hearing) My K3 is factory assembled, so I know it wasn't my fault :-)

I can blow my ears off with the external speaker set to 3:00. Regardless of the NR/NB settings and I've played with the settings for each. This with extremely weak sigs from mid east on 80 and with width settings down to 200 cps. 9:00 with cans and 11:00 max with speaker, usually less. Perhaps there's two groups of K3s out there having different characteristics. Mine is #4495. I have not changed the factory settings for AGC at all. I have played with the NR/NB settings. I've found that although the NR does attenuate the background noise, it improves the SNR such that my speaker/headset controls remain pretty much the same as w/o NR or a tad higher. The gain adjustment on the narrow filters is positive of course. Good luck es 73, Gary W2CS > -----Original Message----- > From: [email protected] [mailto:elecraft- > [email protected]] On Behalf Of The Smiths > Sent: Tuesday, September 07, 2010 3:06 PM > To: [email protected]; [email protected]; Elecraft Reflector > Subject: Re: [Elecraft] K3: Low speaker output problem > > > I've found that if you're working weak signals, and you have your NR > on, and perhaps your NB on, with a tight Width setting it's almost > necessary to run the AF audio pot at 3 o'clock to all the way up.
