>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.

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
