This is a FEMA network. Net control is NNA5HF.---
I tuned in to casual conversation about property drainage before officially seeking check-ins, then having heard a few, then sent digital traffic. Some traffic or other digital transmissions followed. After the initial flurry of activity, there was a lot of dead air (several minutes at a time) between net control transmissions and I did not stay with it.

Not sure if this is an intentional frequency, but I've caught several test EAMs on 7000 USB the past few days.-----

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.
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.
