GB> Origin of 73

[N2EY at AOL.COM]

Some other related stuff:

Phillips Code "19" and "31" refer to train orders. They were so well known
that the terms "19 order" and "31 order" were still in RR use in the 1970s,
long after the telegraph was gone.

The abbreviation "es" for "and" derives from the Morse character "&". The
prosign "SK" with the letters run together derives from the Morse "30".
