[Elecraft] fldigi and flrig and the filters of K3 and KX3

[Don Wilhelm]

Julie,

If Larry can copy CW OK, but has trouble using paddles for transmit, I 
suggest you look into some of the offerings to allow the use of a 
keyboard for CW.  There are several possibilities - the K1EL K40 which 
will allow keyboard operation without a computer. Alternately, the K1EL 
Winkeyer which will give similar capabilities with many logging programs 
- there are others too, just not as popular as the K1EL offerings.
That would allow tuning to the desired CW station with the VFO knob and 
narrowing the filters as needed, and decoding the CW sound 'in the head' 
rather than trying to click on the signal on a waterfall and depending 
on the text on the display to decode properly.
The problem with allowing a program to decode CW is that while it will 
properly decode machine sent CW, and does a fair job even of some 
improperly sent CW, the human brain is more tolerant of variations in 
spacing, dot to dash ratios, bug 'swings' and other variations of hand 
sent code than any software for decoding CW available today.

73,
