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?! 73 Al W1UX -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Sawyer Sent: Saturday, July 23, 2005 11:05 PM To: Discussion of AM Radio Subject: Re: [AMRadio] NNNN >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.

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.
