[CW] List of prosigns

[Richard Knoppow]

    I am skeptical that BT means anything, it is a whole signal, 
not a combination of two letters. It is -...-  not B space T. It 
is always listed as a separator signal. I never heard of HR for 
hand ready and suspect someone made it up.
    The "Marine Radio Manual" has a number of examples of 
messages. It shows [BT] being used to separate the name of the 
addressee, the street address, the text, and the signature. This 
is c.1940 procedure. I rather wonder if [aa] is from point to 
point service where messages were received on an ink recorder 
where it would  be an indication for the transcribing typist to 
start a new line.
