Jerry is dead on with the method used by the military AUTODIN circuits.
NCNC marks the beginning of the message and NNNN the end.  I've generated
and received a lot of these messages over my career.  I don't know about the
other methods, but I imagine you guys know what you're talking about too.
Catch ya on the air waves!

Fellows,

Where does the text "NNNN" originate (radio history) in text messages 
below the "signature" line? I see NNNN used sometimes, depending on the 
particular NWS forecaster, with the National Weather Service text 
messages about active tropical storms/hurricanes (which I might add, 
seem to be frequenting my area lately HI).  Also there is sometimes the 
"$$" being used along with the "NNNN"

Just wondering.

Regards,

Robert WPE4FGR W4RL Pensacola Florida

NNNN is an old wire line expression for end of message, a lot like 30
from telegraphy. 

If the NWS followed their own rules, they would only use $$ to separate
parts of a forecast or report, but sometimes they put it at the end
also.

NCNC should mark the beginning of a message ended with NNNN if I
remember correctly. I put recognizing those in my software so long ago
I've forgotten the rest of the details.

NNNN (4 N's) was also an International signal that disconnected the call and

turned off the radios used to convey the message in International radio 
message traffic. This is (or was) necessary with RCA, ITT, WUI, MacKay Radio

to ships at sea, etc..

NNNN: the international standard EOM indicator.
LLLL: an EOM signal used on FAA circuits.

ZCZC: the international standard SOM indicator. An SOM may not have been 
sent or was unrecognizable when received.
