[Hallicrafters] 5-letter signals

[Gary]

I have to agree with Carl. I to was a radioman, 2nd class on the USS Wasp 
(flat top) and we received telegraph in groups of five. Could be a mix of 
letters or numbers. Many a time I had to rip this out of the old mill 
(typewriter), which by the way was nothing but capital letters, and hand it 
to the OD for decoding.
My 2 cents worth.

BS Yourself.

ALL classified CW traffic was in 5 letter code groups in the USN. The RM's
typed it on a special form and then gave it to the Radio Officer on watch to
take into the decoding room. Replies were handed to the RM's in 5 letter
groups to transmit back.

In early 1961 the first on line crypto machines came aboard ship. These
worked off the RTTY converters and printed out on a Model 15 machine for
starters and then the Model 33's and 35's since the 15's came apart when the
speed went from 60 to 100WPM. It took over a year to get the bugs out of the
system and drop the backup CW transmissions.

As the only ET on board with TS Crypto clearance and training on the
decoding box I spent many hours keeping that crap running. I was in the
radio room when the first traffic came across ordering our group in the
Meditarranean to hightail it to Cuba.
