This is in response mostly to Guy,K2AV's post. I am ashamed to say that I
really didn't know better . Not having much experience with HF equipment I
just assumed that it was meant to be really noisy and just lived with it. :)
Of course this really annoys those around me so it tended to limit
Yes, it certainly IS that simple.
I remember the old radios well. They never had the problem. They
didn't have enough gain to have the problem. Nor was it possible to
have the AGC recover in such a short interval that the noise sounded
as if it were the same level as the desired signal, even
Guy,
Again your ability to write down what is REAL and what is NOT is again
'right on the money'.
This last post of yours should be REQUIRED reading by all new owners of the
K3 to help them better understand the radio, the design and the
capabilities.
Maybe even a version of your explanation
Guy's analysis seems to identify the key point. You can definitely get
better reception under noisy conditions by going into SX-101 mode, turning
the AF gain all the way up and riding the RF gain with your left hand. This
reduces the AGC effect, possibly defeating it altogether, depending on where
Tony,
Why would we want manufacturers to give us a fully auto-magical, panacea
radio that simply becomes a proverbial Black Box that we simply turn on
and speak or operate in other modes?
Elecraft are leading the way I feel in giving us some serious weaponry to
fight widely varying conditions.

Not necessarily - if you have a low ambient audio noise floor (isolating

First of all, thanks for all the helpful replies.
Second, it is possible to get someone to see the light.
Early indications are I like the method of using hi/lo cut for ssb. I just
didn't want to give up using shift and width.
I see how much better this works and also for maximizing the
I have adjusted RX EQ for 'Tone' using my headset. I don't hear the lows
well anymore so I have been able to compensate for that with the EQ settings
and I use Hi/Lo cut for ssb and shift/width for CW.
Audio sounds great for me.

Recently Don Wilhelm posted a K3 fix for noisy audio, I tried it and it
works very well. This fix solved a noisy audio problem I have had for over a
year. I'm an old timer, 88, and the K3 is a young transceiver took a while
getting together. I don't do digital modes or contests just sideband

Turn down the RF Gain. It really is that simple.

Mike,
Don W3FPR has a great article about setting your AGC. Another website
I have found very helpfull is this one:

I had the same problems you have but now I'm very pleased with my K3 ;-)

I set both of my K3s up based on Don's recommendations and found them to be very
helpful.

I've got a 3month old k3. I was impressed with how full bodied or maybe even hi
fidelity some of the audio sounded but I eventually grew tired of how the
background band noise sounded in my rural QTH. The best I can describe is it
had a high edge to it. I eventually went to a vacant frequency
Mike,
It might be the default AGC settings that you are struggling with. If
your K3 sounds noisy between stations, or between pauses in the other
station's transmissions, then I suggest that the AGC Threshold and Slope
settings may not be right for your situation.
