[CW] AR

[Gregory W. Moore]

GA, DR & al,
 Dave, you have it exactly right.  The easy way to remember this is AR= 
"out" as used in Radiotelephone, and K= "Go ahead" as used in 
Radiotelephone.  KN is open paren or left paren (I learned it as "open 
paren"). I never used KN on any military circuit for anything else than 
the aforesaid "open paren"  and I worked a LOT of CW,  (I was USN, but 
had the pleasure of serving beside the USCG at their Ice Patrol station 
in Argentia,.Nfld. (Navy = NWP, USCG= NJN or NIK). Since we were 
co-located, the lines were rather blurred, so I got the chance to hone 
my skills working Merchants, ans shore stations,  as well as Navy 
ships/stations.  This was a great duty station, and the wide exposure to 
all things CW served me well both in my Navy service at other 
ships/stations thereafter,  as well as in civilian life. I can honestly 
say that it made a die-hard CW addict out of me --hi-- but who's 
complaining ;-).


ACP-117 is not a manual of prosigns, it is a manual of routing 
indicators for use with RATT/teletype/Autodin, and all the digital modes 
since then... the definitive work here is ACP 124 (Communications 
Instructions, Radiotelegraph Procedure) of which the latest issue I have 
on file is 1988, but  since the *&^^%$%^  Government "retired" our 
beloved CW & "pounding brass" in 1996, I don't believe that anything has 
changed.

For info/reference, I have posted a copy of the manual (ACP 124) on my 
website which can be found at the following URL

http://www.moorefelines.com/documents/acp124d_radiotelegraph.pdf

Now, this is a .pdf file, so if you don't have Adobe Acrobat reader, you 
will have to go to the Adobe site and download/install a copy (the 
reader is free). This can be found at the following:

Now, if you want to have me put ACP 117 or ACP 121 on the site, let me 
know, and I will be happy to oblige.
