Title: USAF EAM 311.0/323.8 MHz 09 MAR 2018 UTC 2030Z

2030Z 311.0 FALLFISH SWYXDTWTFOFXBLOALPOYEAE2J4TIFJ
2100Z 311.0//323.8 FALLFISH SWYXDTWTFOFXBLOALPOYEAE2J4TIFJ 
2130Z 311.0//323.8 FALLFISH SWYXDTWTFOFXBLOALPOYEAE2J4TIFJ 


At 2100 & 2130Z, I also checked HFGCS to see if it was simulcast on that net, but HFGCS frequencies were silent at that time and when they got around to their EAM it was different than here in UHF.

Heard a few more EAMs after this on the two frequencies, but weaker and a different message. I wasn't able to copy the full message. And the signal was varying.

In doing some research, it may have been a USN E-6B overhead. This is exceedingly rare, as we have very little UHF military traffic (radio or otherwise) in our area. Can't remember the last time I heard anything on 311.0 (since the old SAC days).

Likely an E-6 like you said.   There's probably an orbit in the upper Midwest and you never know when those 2 frequencies will come active.

For E-6B hf traffic check the USN "HFGCS";
13155
11244
8776
6697
4372
(and I think) 3344

Thanks for that list Josh, I'll definitely give them a listen should I hear them again.

Welcome, also include 9031 and 7703 upper for related voice traffic.
