Hi, Probably does not answer your question but high speed CW is still used alot for meteor scatter on vhf...moreso in Europe than in the US and Canada as it has been overshadowed by the various WSJT modes...I never used it but remember some extremely high speeds being used...perhaps recorded in some manner and decoded later? A net- search of hsms or "high speed meteor scatter" should get some hits if interested.
I remember also a few using relatively high speed CW on HF with early computers back in the now-long-forgotten "digital" experimental days of the 80's...it worked well, better than our ASCII attempts hi.... 73 Bill N9DSJ --- In digitalradio@yahoogroups.com, "jhaynesatalumni" <[EMAIL PROTECTED]> wrote: > > Just wondering if anybody here knows anything about high speed > Morse.
