[Elecraft] CESSB (was Re: Software Update for KX3)

[Jim Brown]

FWIW, the benefits of CESSB can easily be approached by a combination of 
judicious use of TXEQ to kill the low audio frequencies below about 500 
Hz, and adjustment of COMP for an indicated 10-12 dB of gain reduction 
on voice peaks. That combination provides an increase of "talk power" of 
about 13 dB -- 3 dB for killing that wasted low end that makes no 
contribution to speech intelligibility, and 10 dB for COMP. This is more 
than two S-units, making 5W as effective as 100W!

I've been doing this and recommending it since my first K3 in 2008. Last 
summer, I had a long ragchew of 40M with neighbor W6GJB, who was at his 
cabin in the mountains with his KX3 and a compromise antenna. When we 
started, he was tough to copy, but when I talked him through those 
adjustments, he was armchair copy for nearly an hour until it got later 
and the band went long.
