It's only a speculation, but I've never heard of that strang of a pattern, especially with quads (meaning the 4-8s) doubles are somewhat frequent, but never in a series like that broadcast was. The only way anyone might be abl to figure out what it might have been is to check from that time stamp, forward to about the 25th to see if there was a major strike somewhere, or either a big stand down.I can't do that with this old computer. I continue to monitor every day, but since the exercise, the amounts of messages have slowed somewhat. In fact, there was absolutely nothing on the 24th and 25th. 5 on the 26, and 4 yesterday. Only one was repeated, which was yesterday at 1650 and 1652.
