[Elecraft] K3 CW Text Decoding

Tue Oct 8 00:23:13 EDT 2019

If you haven't played with CW Skimmer much, here's a couple of points of 
interest.

1.  You can run multiple instances.  I fed the Line Out from my K3 into 
the sound card of my computer, and had one instance of CW SKimmer 
display a waterfall of the narrow band audio from the main receiver and 
another instance of CW Skimmer display the narrow band audio from the 
sub receiver.  You'd be amazed at how distinct the dits and dahs look 
compared to just about every other waterfall application I've ever 
seen.  You can shrink the vertical display height of both instances of 
CW Skimmer to make them fit above your logging program on a decent sized 
monitor.  Imagine being able to pick out the callsign of a station on 
VFO B while you are focused on working somebody on VFO A ... even if he 
gave his callsign several seconds before you looked at the VFO B waterfall.

2.  There is a command that will pause the CW Skimmer waterfall. It's a 
toggle ... hit it once to pause and hit it again to restart. I don't 
remember the command off the top of my head but I remember mapping it to 
a key on the keyboard using the outstanding free application called 
AutoHotKey.  I didn't have to use it very often, but any time I blew a 
received report I'd just tap that key and it would let me visually 
decode whatever I busted and correct it after the contact, and since the 
display was paused I could do it when it was convenient.

3.  If you turn off the decode in CW Skimmer it is simply a waterfall 
and qualifies for unassisted categories, but the visual display cuts you 
a lot of slack for human decoding.  Just read the dots and dashes in 
your mind as dits and dahs and you'd be surprised how quickly you learn 
to decode visually ... except now you have a "do over" capability to 
help you out, or alternatively have a brief record of whatever is 
happening on one VFO while you are active on the other.   It's almost 
like turning one operator into one and a half operators.

4.  You don't need ANY additional hardware to use CW Skimmer in audio mode.
