250614 HFGCS Emergency Action Message
A 246 character EAM broadcast today. Recording of transmission (which 20 minutes to broadcast!) and text transcription in the replies ⬇️
My uneducated guess on the tanker deployment;
U.S. Air Forces in Europe-Air Forces Africa will participate in Atlantic Trident 25, a joint, multinational exercise bringing together Finnish, French, U.K., and U.S. forces [...] June 16 to 27.
There are currently 5 E6Bs airborne; it may be a day they end up communicating with each other on the CHARLIE ECHO WINDOW (9031 kHz) or another CHARLIE WINDOW. There might be two trying to contact each other on 11175 kHz right now.

In this post, I'll be going through the usual information about the HFGCS – "What is an EAM? What is a SKYKING?" etc. – even if you've read this kind of thing before or watched a video about it, this contains information I haven’t seen discussed elsewhere, and some original
11175 kHz
22:25 UTC – SKULL01 radio check [B52]
B52s seems like they might be a little more active on the HFGCS lately. Around this time last year (Oct 03/04 2024) we heard a lot of interesting radio traffic relating to a B52 exercise about the Nevada Test and Training Range

callsign: GRAY MARE

· First broadcast by ground stations at 2118z and GRAY MARE at 2123z.
· GRAY MARE is an E6 somewhere over western US or Pacific.
· For new followers: it will probably broadcast again at 2220z!
The signal which is tying up the US military's 4724 kHz HFGCS band is still present (it is now at least the fourth day). Reception has consistently been strong in Europe throughout. What do you think?
- Reception on 11175 kHz was iffy (not even the Montana SDR I've found to be the best at HFGCS reception got it) so my stream didn't pick it up very good.
- For the other 246 characters I have transcribed, most are from 2023, and they were all broadcast on Sundays. 2024 breaks
