best agc setting for the k3s

[NOEL POULIN]

Hi,
I am a new owner of a K3S.
I would like to know the best AGC SETTINGS  for the K3S
I mean  AGC DCY, AGC HLD, AGC PLS, AGC SLP,AGC THR.
I am not very satisfied with the default setting...
Most of the time I'm working CW, RTTY...in contests
Can somebody tell me about his best setting for these modes....
Working only in contest .
Thanks
Noel

Noel,

For the SLP and THR settings, take a look at the "Noisy K3" article on
my website www.w3fpr.com.  Those 2 are the major ones governing how much
noise you hear on a band between pauses in speech or between
letters/words on CW.
The article gives you guidelines for determining the best setting for
the type of operating you do and your personal preferences.

For the other settings, I find the defaults are quite suitable, but you
are welcome to experiment.

73,
Don W3FPR

Noel,
This subject is well discussed on this reflector from time to time.

I suggest starting with the discussion on Don's (W3FPR) web site -
http://www.w3fpr.com/.
Go to the "Noisy K3? - Adjust your AGC Settings" section. That paper has a
very good explanations of the K3 AGC system operation.

For a discussion of each control with suggested values and why beyond the
Elecraft Operators Manual.
http://www.ve1zac.com/Jeff%20Smith%20K3%20AGC%20R1.pdf

You can chase your tail until you understand the settings and how they
interact.
Go to Fred's (KE7F) "K3 AGC Story" sections at http://www.ke7x.com/home.
Fred has written tutorials on deciphering the Elecraft manuals with step by
step instructions.
I do not have any of his books; however they get very good reviews on this
reflector!

Personally - I refer to the transfer graphs. That helped me understand the
AGC operation on my K3 & KX3.
http://www.ke7x.com/home/miscellaneous-k3-information/agc-4-51.  I have a
laminated copy of this graph in my operating desk!
Also refer to these as well.
http://www.cliftonlaboratories.com/elecraft_k3_agc_and_s-meter.htm.

The Elecraft AGC system allows you a large room for adjustment to allow
different modes of operation and preferences.
Unfortunately this also means that there is a learning curve to get it "Your
Way"!
"Your Way" may change depending on the mode and band conditions.

Hopes this helps a little.

Here are my settings:

dcy soft
hld .2
pls nor
slp 0
f 200
s 20

threshold:
CW - 20 for max dynamic range to separate callers in a pileup
SSB - 15 to prevent harsh sound of thr 20
RTTY - 10 to prevent overdriving the sound card on loud signals

Front panel AGC FAST, except SLOW on RTTY, as recommended by G3YYD

By the way, Elecraft guys, it would be nice if the AGC Threshold were remembered by mode.

Without being judgmental :-) this is bad advice. SLP 0 and THR 20 in
effect turns off AGC. Maybe there are times when you want to do this,
but probably not in a contest, when you want to protect your ears.
