[Elecraft] K3 AGC improvements (MCU rev 4.50 / DSP 2.74)

[BobK8IA at aol.com]

Compared to the many others that have weighed in already, I am a few  days 
late taking a look at the new firmware. It may have been worth the  wait.
 
In a nutshell, the new 4.50/2.74 works extremely well. I've been waiting  
for my K3 to really be able to perform in deep pileups, like I had thought it 
 should. With the new firmware, it may be very close now.
 
Even though it may be a few weeks (until CQWPX CW) when I can make a full  
evaluation, in fairly deep pileup conditions, I don't need extended testing 
to  see a big improvement already. K6LL mentioned "the difference  is 
immediately obvious". I fully agree.
 
The ability to be able to extend THR settings has noticeably cleaned  
things up. My sweet spot seems to be THR=15 and SLP=0 or 2. More evaluation to  
come.
 
Tnx Elecraft Team for looking into this issue and releasing this  
"pre-Beta".
