AGC Settings

After installing the new Synth board in my K3 all is well except I
notice that on strong CW signals the AGC is not keeping that signal from
blowing my ears off when listening to a DX pileup.

I am mostly a DX CW operator, and my present AGC settings are:

AGC HLD = 0.30
AGC PLS = NOR
AGC SLP = 002
AGC THR = 008
AGC-F = 120
AGC-S = 020
AGC DCY = SOFT

Can't remember where I got those settings but was from some post or
blurb somewhere.

Thanks for any suggestions, Donald K6RV

Re: AGC Settings

Donald,

The AGC settings, particularly the slope and the threshold are best set
to your individual preferences. There is no setting that is perfect for
everyone - that is why Elecraft allows the parameters to be varied
instead of providing one setting for everyone.

For guidance on how to evaluate the results of any changes, take a look
at my webpage www.w3fpr.com article on "Noisy K3".
The key is that you cannot make a good evaluation by listening only to a
signal, you must listen for the effects in gaps between the words of a
signal.

Re: AGC Settings

Agree with Don't comments. If signals are blowing your ears off, you need
one of the following:

lower AF Gain
lower AGC Threshold
higher AGC Slope (higher SLP value is actually flatter curve which
technically is a lower slope)

I encourage everyone to learn and understand how to set up their
manual/auto gain settings, and not just willy nilly copy other people's
settings.
