[Elecraft] Rev 4.51 firmware - what AGC settings worked on bigpile-ups with loud AND weak signals in the WPX?

[Dave Hachadorian]

I used the AGC settings mentioned below for the entire WPX CW 
Contest this weekend, and they worked well for me - 1750 QSO's on 
15 meters.  There is a sweet spot for the RF gain control, where 
more or less makes extremely weak signal less readable.  I set 
the control at that point, and rarely had to adjust it, only when 
there were multiple very loud stations calling me in a pileup. 
AF gain was kept at a fairly low level.  Basically, it was like 
operating with AGC OFF, except for the very loudest signals. 
After using the new firmware for 32 hours in a contest, I think 
it is a significant improvement.  The linear range of overall 
gain from the weakest detectable signal to the point where 
compression begins has increased noticeably.  On 15 meters, I had 
the preamp ON and attenuator OFF.

G'day



Unfortunately my tower has been down for a couple of weeks now 
owing to a
dead rotator and I missed out on playing around the new 4.51 
version AGC
settings in the WPX CW.  I'm sure those of us on the reflector 
who couldn't
get on in the WPX CW would be very interested to see what worked 
out.



Prior to the contest, at least one serious contester (K6LL) was 
going in
with fast AGC, using the minimum of RF gain (no preamp) and the 
following
menu settings:



AGC Decay: soft

Hld: 0.2

Pls: nor

Slp: 0

Thr: 20

F: 200

AF lim: nor 030



This seemed a pretty good set-up based on my own experience - be 
great to
hear if these setting worked for both loud and weak signals and, 
if not,
what did.  All comments would be appreciated!



Many thanks!
