Reduce your RF gain, Use the attenuator on the lower bands. The reason it is the same with the AGC on or off is because with AGC off the receiver is running full bore amplifying all the background noise. You must reduce your RF gain until the background noise (hiss) goes away so the signal

The article regarding AGC at w3prf.com was most interesting and informative. I am now experimenting with the AGC settings much more than I had. So far this morning, I am enjoying the K3 far more than I have in the past. This may just be the magic bullet for the hiss problem that has bothered

That website is www.w3fpr.com. The article was created before the AGC parameters were expanded, but the principles are the same. As it has been said here, turn off the preamp if it is not needed, and even add the attenuator. If you hear an increase in noise level when you connect an antenna,

Bill, What is your setting for AGC - THR? It sounds like you may have it set to a low value. I have mine set to 20 (you'll need recent firmware to enable this), and find that setting the AF gain to a comfortable listening level positions the background band noise way down for all but the

Mike, You say it is not AGC, but I would not be certain of that statement until you have done some trials. I suggest you read the noisy K3 article on my website www.w3fpr.com. There have been changes to the AGC menu parameters since I wrote that article, but the same principles apply. 73,

I have never heard any hiss whatsoever with my K3 (s/n 1397) either on speaker or headphones, CW or SSB and I am particularly sensitive to such things. My TS590 does have some very low level hiss which I can live with Ok and I had a TS480 which had quite pronounced hiss. The worst I have heard

Hi, This was a common complaint in the past. Elecraft engineered a retrofit low pass filter for the RX DSP board which cuts off above 4kHz. Or you can swap out for a replacement DSP board to revision D status where the LPF is fully integrated. You might like to investigate what the status

So, I assume you guys are talking about hiss that is even apparent on a quiet band (such as 10-meters when it is dead). If the hiss only occurs on a band with regular atmospheric noise how do you know to distinguish between the two or maybe even what components of one over the other. 73,
