> So a fake alert can be sent out nationwide from broadcasting to just one access point??

I believe OP meant "country" as in "countryside", which is feasible when you're up on a hill and your signal can reach a distribution source antenna (which will then distribute your spoofed alert to its attached sirens).

No, I meant the country as in the United States. EAS on the national level works by playing telephone: hopping the alert from station to station in a mesh configuration. PEP stations are origins for national alerts.

Oh wow. Clearly, something like widespread availability of SDRs was not an issue back then.

I wonder why it hasn't been abused/trolled on a large scale, though. Really, if I were interested in trolling that's what I'd do: next to zero chance of the cops catching you as you won't leave a trail, plus the entire country will be wide awake once the sirens ring and it will likely need months or years until the government secures the stuff.
