I've played with a few decoders, Steve -- more out
of interest than anything else. The one I've found
most promising is in the NUE_PSK modem. See
http://www.nue-psk.com/cw/index.html#Receive_ and
http://www.nue-psk.com/doc/CW%20Mode%20for%20the%20NUE-PSK%20Digital%20Modem.pdf
But even there you have to make adjustments for
variations in character and word spacing.
Personally I'd hate to see Elecraft devote much
attention to optimizing CW decoding, which is a
pretty specialized field.

Hi Gary,
Yes, and it's curious that there are clearly better decoders out there. I built
an Open QRP rig last year and the decoder was phenomenal...much better than the
KX3, so assuming this is a software issue, is this something that the Elecraft
engineers are looking at?

Not sure if it's comparable to the KX3, but I find the current K3's decode to
be relatively worthless compared with the original version I owned years
ago. Something has changed and somewhere I read it was given it's own AGC or
whatever for an improvement.
I can send and receive CW to my satisfaction, so for me it's just something
I use as a background visual source for my P3/SVGA/monitor while I'm doing
something else.
If I want to really decode some contest 30-40 CW I use the small portable
audio-fed Microcraft Multi-mode gizmo I bought years ago. Works perfectly
while the K3 fumbles with the same source. Only the loudest and clearest
gets unscrambled.
