is QRSS really computer generated? Wow, thats the reason all your signals
are keyed thah exactly! I allways sit here and key down (to make things
easier with my left foot) and slowly count to 15 when I send a dot! Same
on receive! I was never sure about the real advantage of Slow CW but I
thought some people can't give or receive faster than that so thats why I
used it!

BUT, I remember when Peter Bobeck first used QRSS with DA0LF. He was heard by several UK stations before we had the band here. He used 10s dot length, and the early version of Spectrogram would fill the screen every 8 seconds or so. I well remember using a stop watch to time each element and then write it down as dots and dashes in order to read it!! I also know of at least one LFer who has sent QRSS manually.
My QRSS is sent using a memory keyer with many megohms
switched in series with the timing capacitor - is that computer
generated?
Also of interest is that I can now read (audible) QRSS by ear if I
concentrate. It took about a year to get used to doing it but it's now
easy. There is very little practical advantage in this of course
(perhaps a dB over conventional speeds, and rather more in high
QRN) but it is interesting that the brain can be trained to do it.
