[CW] List of prosigns

[D.J.J. Ring, Jr.]

Right, you are Hans.

In amateur radio traffic handling practice AA (overscored) is
separator used in addresses.

DAVID RING AA
14 MAIN STREET AA
ANYCITY, USA AA
BT

Allied Navies and world-wide merchant navies, didn't use this, we just
ran the name and the address together, trusting it would make sense.

DAVID RING 14 MAIL STREET ANYCITY USA
BT

But we DID use BT to separate the preamble (message number, office of
origin, date) from the address, and address from the telegram text and
from the text of the telegram and the signature.

We also used KA (prosign) which is "STARTING SIGNAL" instead of HR.

It must have been in a general amateur / commercial book because I
think HR and BT came from American Morse and since many of our
original traffic (message) handlers adopted Western Union procedures,
it carried over to Amateur Radio Traffic Procedures.

That and suitable money will buy you a cup of tea and a doughnut.
