I suspect that's exactly why the "official" record stands -- these guys
aren't transcribing -- just conversing -- which, from what I know about
them, is much more the point rather than boasting (no disrespect
intended to McElroy -- quite an achievement on his part).

This sounds interesting.  I've never heard much about it.  Are high
speed CW ops using this in lieu of "the real thing" to get around rigs'
limitations?  Since it's on SSB, I assume it's not legal down in the
conventional CW portion of the band.  It sounds like it could be an easy
way for QRQ CW to operate from any rig in the 70 to 100 range, or so.
