After several weeks of quiet, finding 5723u acive again at 04:26z with calls ID'd EW, K, L. Also UNID digital transmissions
This has peviously been ID'd as known Naval freq (thanks CM), wonder if current sigs relate to USS Enterprise (the carrier, not the spaceship I believe) Composite Unit Training Exercise, the COMTUEX was just reported today by the ever reliable Jack Metcalf on his blog: http://mt-milcom.blogspot.com/
May also simply be a MARS net, though not on my MARS net freq list (also courtesy of Jack Metcalf, he and Hugh Stegman being two of the increasingly few reasons to still purchase the occasional (overpriced and pirate ignoring) Monitoring Times.)
So far hearing calls every 15 min or so, though reception here getting iffy. .

I was hearing stuff yesterday around there at ~1330z.
Data bursts. Passed by them as broadband noise, but as you jog the dial, you can definately tell it's a signal. Spread spectrum?
Peace!

5723u active again this evening with fascinating, though only intermittent comms, presumably relating to military exercise. Echo, Echo Whiskey and Lima active, (though at times only barely readable here),also references to "Jimminy Cricket," relating to (UNID) maneuvers. Pretty sure they're not talking Disney here. Cool stuff.
At 03:00z track reports from Oscar and Juliet and Vampire.

At 03:00z track reports from Oscar and Juliet and Vampire.
There was no track report from Vampire, Vampire is the designation for a missile in the air. And there is no such thing as a friendly missile, all missiles are Vampires, but outbound missiles are not reported normally.
Last night there were multiple engagements on tracks, all tracks engaged while I listened were air tracks. Aircraft or missiles. Naturally, the missiles were simulations, either purely virtual or possibly aircraft playing the roll of missiles. Tracks would be designated, identified, engaged, and splashed. For example, at one point last night track 2102 was the track ID assigned to a Vampire. Track 2102 was then splashed by one of the platforms.
The single letter designators, Oscar, Juliet, Mike, etc, are individual units in the task force/group. There is no way to tie one of these designators to a specific platform. Net control can be anyone in the group, not just the carrier. Net control can shift from one unit in the force to another, as needed.

Great info! Any idea which ships etc were participating in this exercise, where this was happening?

This is most probably the source of these signals:

There are a couple of other frequencies associated with this EX also, 4712 and 8974 kHz.
