[Elecraft] K3 CW text decoder

David...

I think one hurdle to leap is accepting that one is learning a second 
language, and that regardless of learning method, time and repetition is 
necessary. I think that people tend to look for a short cut to learning 
CW, some trick that will take the work out of it.

Given that, I have found two computer programs very helpful to me for 
increasing CW speed. RUFZ allows selection of individual 
letters/numbers, groups of any length, and any speed desired. I've set 
on a pattern of 3-letter groups at 40wpm, 4-letter groups at 35wpm, etc 
all the way down to my base practice of 7-letter groups at 25wpm. The 
program requires keyboard entry, and it keeps score. Lots of goodies. I 
think this program helps with "mental dexterity" and the associated 
skill of moving forward and not getting bogged down with individual 
letters.

The second program is G4FON which provides random words at all letter 
speeds and word speeds. Sample qso's are also included. I've made up 
several text files of words from three letters long up to 10 letters 
long. This provides the "sound of the word" as others have mentioned.

I've been going back and forth with these two programs, usually 15min 
with each for one learning session, and I try to do this daily. I also 
tune 40m and look for folks having high speed qso's, and listen in as 
best as I can. Using these three methods together, my qso speed is 
pretty good at 25wpm with 30wpm coming into sight. All this at age 72 
years.

Also to note, one doesn't need to copy perfectly to figure out what's 
being said. If one copies "ant__na" it's pretty clear that the word is 
"antenna." The same with whole words. The meaning "emerges" from the 
stream of dots and dashes rather than lining up sequentially. At least 
that's what it's like with me.

So, to summarize...
lots of practice [and patience],
listening at high speed to small groups,
listening to words at all speeds, and
eavesdropping.

Not to mention getting on and doing CW qso's!

Good luck.
