Military sending abnormally high amount of EAMs all day

Maybe the subs in the pacific are doing nuclear missiles drills just in case NKorea goes nuts and they need to nuke the shit out of them.

Radio-tard here. Been listening to shortwave all day and the military has been sending an abnormally high amount of EAMs (Emergency Action Message)Most have been from Andrews AFB and Offut AFB

For those who don't know what an EAM is here is some info: [link to mt-milcom.blogspot.com]

And here's an example of what one sounds like:

fascinating...didn't know about these until this thread. Amazing they've never been decoded.

B52s stationed there?

Thank you for the bump. I wish I was able to decode them. If anyone has a sideband capable shortwave receiver tune to 11175KHz and 8992KHz as it begins to get dark. Mode is USB. I haven't heard one in about 20 minutes now.

Love that movie, and that makes sense to me. Unless there's something else big going on out there we don't know about

B52s stationed there?

I drove thru Omaha today, nothing unusual on the radio. I'm in Lincoln now & have the TV on, nothing there either.

could be transmissions from the US/SK drills?

This is interesting indeed. What could be the reason for the EAM uptick? Perhaps it is somehow connected to the Korea Crisis? I wonder if we in Russia have something similar. Then we'll know for sure if things were going down.

Could it be the Fandango Rangers are picking up more chatter than usual on the ol' backside?

Another EAM coming through.

They cannot be decoded as they are not code. They might as well just say, "execute instruction 5" as these messages reference pre-written instructions. Unless you've got their book of instructions, they could mean anything.

Exactly.. if you dont have the book (current distro) then "21Z" has absolutely no meaning. I would be worried if they also begin transmitting authentication as a footer to the msg.

There are exercises occurring near NK with the US and SK at this time.

According to the MT website you referenced:

"According to the instruction above an EAM may pertain to "a real emergency, a scheduled exercise, or a special test." So one of the important things that monitors need to keep in mind is that not "all" EAMs involve critical real world events."

I'm guessing it's related to the exercises.

Near Omaha, Nebraska. Since it's shortwave the radio waves travel around the world.

I know, I listen daily. I said there has been an "abnormally high amount of EAMs" all day today.

Yep.
The spoken EAM's are encrypted keys.

Still strange why they voice transmit them versus using digital means.
Must be for some security reason.

Could be for reliability and interchangeability.. the spoken word can be decoded by any human with the red book and authentication tables.. the packet modes would require some other complex gear (much like a pactor)that would add to the complexity of the system and also packet modes are not as fool proof as phonetics sent in the blind and picked up by the Mark-I human ear.

Op... Are they on 11175 still or moved over to night channel?
