[CW] List of prosigns

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

Thanks Hans,

There was one book I read that had the explanation about HR and BT.
It was a non-ham book, I don't know what the name of the book was, but
thanks for the correction on the number of the ACP volume.

I have lots of books on seagoing radio, going back to the 1920s and
30s, but mostly post WWII.

Does anyone know where I might have seen that BT means "Begin Text"
and HR means "hand ready"?

I really believe it was a U.S. Navy publication and that I was very
impressed at the quality of the research they did on the subjects they
wrote about.  That's my impression, but maybe it was a book on the
subject of communications, but I can't remember, but I was impressed
by the knowledge.

Anyone know?
