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.

a hold-over from CW traffic-handling days that meant "No more" when
passing traffic.
Teletype (RTTY) operators carried it over, when they started pounding on
keyboards
somewhere in the '50's, when passing traffic over ham-radio was still
'en vogue'.
today, when you hear the packet bursts of the Emergency Broadcast System
alerting
you to the fact of either a Test, or an actual emergency, the 3 short
bursts at the end are
N N N (no more)
That's about the best I can do, for a description.
Anyone else?
