[Elecraft] K3- Separate AGC settings needed for: CW, SSB, RTTY

[RLVZ at aol.com]

Ed's message is another confirmation on why it would be really great  if 
Elecraft would modify the K3 software so the MENU would allow  us to select 
separate AGC settings for: CW, SSB, and RTTY.  
 
I realize this may be a first, but Elecraft is good at leading the  pack!

Below is  a thread from 7 March 2016 about AGC usage with RTTY decoders.
David Wicks,  G3YYD, is the author of 2Tone and Kok Chen, W7AY, is the 
author
of  CocoaModem. 

Anecdotally, my experience after 250,000+ RTTY QSOs over  the past 15 years
concurs that minimizing AGC action supports best decoder  performance.  If 
my
ears, or widely varying signal levels, can't  tolerate AGC Off, then I use
AGC Slow, SLP=0 and THR=14 or  higher.

Note also the comments about receiver IF bandwidth of 500 Hz  except in
extreme cases.  Even in big RTTY pileups such as I encounter  sometimes in 
DX
locations, Again, I've anecdotally found that 500 Hz  decodes better most of
the time.  I seldom go lower.  This also  implies turning off the K3
Dual-Tone filter.

Both of these points  (no, or minimal, AGC and moderate IF BW) are not
intuitive, especially for  an experienced CW operator.
