[Elecraft] FW4.51 CWT

[Mike Harris]

Hi Lyle,

OK, I wasn't able to put any figure on it.  It just didn't seem so 
lively.  I was listening to some CW on 40m, low output antenna and even 
some elements clearly audible above the noise didn't cause the CWT bar 
to display.  My AGC settings at present are pretty much pre 4.51, 
Threshold 8 and slope 6.  TEXT DEC is Auto, not that I ever use that 
function.

Regards,

Mike VP8NO
