[Elecraft] QRQ CW

[Charlie T, K3ICH]

Back when I worked at the "old" Microlog Corp in Gaithersburg MD in the late 
70's, we found that a lot of rigs couldn't be keyed much faster than about 
50 WPM.   Key click filtering etc., made mush of the faster CW.    A keyed 
string of dots looked like the output of a half wave rectifier !   To get 
around this limitation, in order to run >100 WPM CW, we'd revert to AFSK 
keying, copying the Mark frequency only.....worked like a proverbial charm. 
It was like having our own private encryption system as nothing but a 
computer assisted copy system could decipher it.    We never really asked if 
it was legal though.

And, to my knowledge, there was and still is NOTHING out there as good as 
the decoding algorithms those programmers wrote.  (The main one just 
happened to be the president of the company.)   I  tested every piece of 
competitive equipment I could get my hands on to prove this point.  Microlog 
was the absolute king-of-the-hill for CW copy, hand sent, bug sent or 
otherwise.  In order to fool it, you had to purposely send "rotten" code.
