Yes, EAM is Emergency Action Message. And they go out all the time, whether they mean anything or not. If they only went out for something
important, that would be a tip off that something is about to happen. Generally there are 2-4 per hour. But a couple of weeks ago they have become
more frequent. They are just an alphanumeric message addressed to an alphanumeric receiving station. The ones I mostly hear come out of Andrews AFB
and Offut AFB. The sending station does identify itself at the end of the message, ie. "Andrews Out"
The "SKYKING, Do not answer" messages are rare. The last time I have heard one was during the '08 Olympics when Russia and Georgia got into it.
And I have heard 3 of them in the past 2 weeks.
Do a you tube search for "eam" or "emergency action messsage" there are plenty of recordings.

Now, as to the traffic I have been hearing. It seems like a roll call. The frequency will be quiet for a while, then lots of stations calling to
check in, then quiet again. I haven't noticed any kind of schedule. It is kind of random. But it is something I have not heard before. Like I
said, the good stuff is surely encrypted, as in, once contact is established they go secure.
I'm in N. Texas and I can only hear them after the sun goes down. They are probably happening all the time, but I have recently moved and have not
had a chance to set up an antenna and my radio station, so all I have right now is a portable radio. I am mostly interested in the ham bands, but
since I can't talk back right now, I'm listening to other things.
Sadly, I am unable to make recordings as my Mac is out of commission due to a bad fan, and the computer I am using now does not have the necessary
It could just be an exercise, but whatever it is, it seems to be on a large scale. As there are at least 20-30 units at each "roll call".
