This file "robocopy.txt" added/written by K4QXP.

Included with this file, in ROBOCOPY.ZIP, are three files which I
downloaded from 73 Magazine's BBS on 21 SEP 1990:
   ROBO.ALG   the algorithm, an explanation of the software
   ROBO.C     the C language source for the .EXE
   ROBO.EXE   the executable

The October, 1990 issue of "73 Amateur Radio" has an article titled
"ROBO-COPY", beginning on page 28, which describes the use of this
software on a PC computer to copy cw (Morse code).

The article also gives details for building the interface that's
needed between the radio receiver used to listen to the cw,
and the computer.

For the benefit of readers not seeing the magazine article before
reading this, here's the parts list (to help you decide if you want
to go after a copy of the magazine).
