Inspired by SWLing Post reader @K7al_L3afta, a few weeks ago, I monitored 15,016 kHz for US Air Force EAM (Emergency Action Messages).
I’m no expert on military communications, but I did manage to catch a few messages–that I assume are EAM(?)–on the same frequency.
All of these recordings were made on the afternoon of February 15, 2015 on 15,160 kHz in the upper sideband:
My buddy, @K7al_L3afta (on Twitter), posted this interesting recording of the US Air Force High Frequency Global Communications System on 15,016 kHz USB at 18:01 UTC yesterday:
I don’t believe I’ve ever heard or noticed this type of USAF HF-GCS transmission before. Sounds almost like a numbers station.
Update: SWLing Post reader, Daniele, comments:
It’s an EAM, “Emergency Action Message”:

Thanks, Daniele!
As I’ve mentioned before, @K7al_L3afta lives in an urban area of Morocco and his shortwave radio listening is plagued with radio interference (RFI). Still, he seems to snag some interesting catches on the shortwaves just like this one which he said he caught by “turning the tuning knob randomly.”
Serendipity is, indeed, the best type of SWLing!
