[CW] Morse Code Podcasts

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

Richard Knoppow,

Asked a question about the history and use of AA prosign - di-dah-di-dah
sent as one group.  I'll write that as AA

AA is American Morse code for comma.

Some Western Union / Railroad procedures were carried over to International
Morse in USA and Canada.

AA comma separates amateur radio radiogram addresses.

123 Fun Street AA
Lost Angel, CA AA

AR had a meaning but I forget what it was.  It's also cross + in
International Morse and is the turn around signal.

GA or Go Ahead is used in RTTY and in TTD for deaf and Telex for go ahead.

In SITOR / AMTOR it is  GA+?

BT is Begin Text and it starts the text of the message.  It's the double
dash or = sign.

There are two signals that are to alert the receiving operator.

KA which is "Starting Signal".

HR which is "Hand Ready" as in KA HR NR 1 DORCHESTER MASS OCT 28 2012Z =

I'm sending to the group because that way it gets in the archives.

I'll have to search the archives to find out what AR means.  I forgot.
They all had names BT SK AR.
