: Go back in the LWCA message archives or better yet ask some of the
: oldtimers like JD, Jay W1vd , John w1tag, or Dex w4dex. Alberto who
: wrote ARGO is a member of this forum.

Alberto responded to the fellow, said he was playing with QRSS prior to his
writing Argo.  I set up my first beacon in '04 after reading about it on the
lists for a few years.  Some fellow commented on using QRSS RTTY in the 50's 
and noticed a much better through-put, so, it seems to be a pretty old 
technique.
