More Long EAMs

Jeff Haverlah continues to monitor long Emergency Action Message transmissions on the US Air Force High-Frequency Global Communications System.

On July 22, the hour/half hour restoral EAM from McClellan Global consisted of two messages of 52 characters each.

At 1721 UTC, Andrews broadcast the longest EAM yet - 287 characters! It had the distinctive repeating formating and the typical 14-character ending block. Unlike the usual Saturday activity, this was on a Sunday, and not by a Nightwatch player using a tactical callsign.

I wonder how long THAT one took to transmit, in the slow US Air Force drawl.

[UPDATE 03 AUG: Sometime in July, Tom Sevart heard Andrews with 270 characters at 1800.]
