I recall a discussion about how to best specify the QRSS speed on the
Lowfer mail list. This must have been over 5 years ago. I looked for
the message archives on qth.net but the messages prior to 2000 are not
there. John, W1TAG, was the first I remember to use the QRSS(#) term.
About the same time Alberto released a new version of Argo or Spectran
which included the QRSS speed. Also I don't know which came first, the
chicken or the egg.
