b.b.:

They are not "sending code so poorly that a pimply-faced No-Code Tech with a
code reader..." can't read it, they are attempting to send so badly that a
computer running software coded by one both CW and computer savvy has set up--I
suspect they think themselves smarter than the computer... maybe... grin

Indeed, a very good programmer would inject "nuances" into the way the app
translated his keyboard code to morse, making it virtually impossible for them
to tell they were copying automaton generated code, at a very respectable
speed! grin

I would think it would be a game, an enjoyable one...


John, that discussion took place in here a few years ago, my
remarking on what I'd seen, lent my Icom HF receiver for an
air test, on an ADAPTIVE decoder for morse. It was written
by a professional programmer as an intellectual exercise for
his own benefit, just wondering if it could be done. The
ADAPTIVE part was in automatically adjusting to the differences
in weighting of dits and dahs, their combination resulting in
a word rate equivalent. The ADAPTIVE part took most of the
source code...the translation of morse characters to ASCII for
immediate display was a small, small part of the source, just
a small look-up table in effect. It was done on a medium-old
clock rate PC but would be a snap to work at a 2 GHz clock.

To reverse the process, to add weighting to dits and dahs, even
to having different weighting for different characters, is a
snap with a random number routine. That wasn't done, but is
viable without much alteration of the source.

The PCTA extras in here will have NONE of such things! They
will attempt to THRASH anyone in a monumental display of deus
ex machina worthy of the most devout Luddite. shrug
