>From my Navy days, that was the lead in and exit of a teletype message. I
believe it had more to do with tuning and synchronization of the receiver
than it does with the actual message.

Subject: [AMRadio] NNNN
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"
