Over modulated (here) OM/YL giving phonetic terms (Oscar, Foxtrot) for stretches of time.  Pauses and starts again.  Can not decipher most of words spoken.

Heard tail end of what sounded like an EAM on 6833 USB about  0:15 UTC.  Maybe a USAF HF comm exercise?

That was a USB signal from a USN station on 6988.0 with a exercise EAM.

Are these typical USN EAM frequencies? I'm not familiar with them.

No, they're just used in specific exercises.

Some people have dubbed this activity as the "oddball frequency" exercise.  It is presumed the EAM/FDM style messages are being transmitted by Navy ships on a specific scheduled.  Call signs tend to the Navy style 3-character alphanumeric variety such as Bravo Nine Mike, of Seven Alfa Yankee.  One interesting observation is that the messages themselves seem to be different than the EAM/FDM messages being broadcast on the HFGCS during the same time frame.
