Interesting discussion, Carl.  I was in the Army ASA from '47 through
'52.  Was NCOIC of DF control in Korea after the war disturbed our
normal life in Japan (g)  We also used 5 character groups but didn't
use crypto machines for operational immediate traffic.  We used one
time pads since the info was for immediate use and of no real value
after the fact and one time pad encoding wasn't very easy to break.

As far as routing indicators for RTTY in civilian life, in my last job
with TWA '74 through '91, I was MKCXPTW for interline traffic or just
MKCXP for intra-TWA traffic.  MKC for Kansas City, XP for communications
planning and TW for TWA.  I was responsible for all comm planning,
installation and performance throughout the world for TWA.  The same
type of routing indicators were used by all the airlines.  I was lucky
enough to have stayed in communications of one type or another for
my entire "work" career.  Everything from radio, teletype and data comm
as it went from hardwired RTTY stuff to computer processed RTTY and
CRT traffic.  Our data comm circuit billing exceeded $2,000,000 per
month when I retired.  Those were the fun years (g)
