[MilCom] [Militaryscan] MIL: 11175.0 USB - TROUSERS and COAL OIL

[H i!]

I just down parked on HFGCS freqs on HF, if that's what they're still
called. Used to spend a lot of time doing that. Here today at least I am
finding a lot of EAM activity. Is this just b/c of recent events or has
this density of transmissions been upped for awhile now?
