A lot of those old messages (as I remember copying them on my rtty stuff in
the '60's) not only had NNNN as separator,
But also "ZCZC" - a common separator I'd see would be

NNNN
ZCZC

Any clues on that one?!

believe it had more to do with tuning and synchronization of the receiver
than it does with the actual message.

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.
