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
