[EAS] Alerting options

[Mike McCarthy]

I never suggested VLF.  I specifically kept the window to low band wide 
coverage AM's (Class A's and a few B's).

While one station could reach most of the CONUS, why build a new 
infra-structure when the PEP and other interested stations could perform 
the same thing using existing installations?  Even if the feds paid for 
all the encoders and receivers to 10,000 stations, that would still be 
less than one VLF station built for this purpose.  And we'd get good 
Alaska coverage too.

One other thing, we don't need to be the alert issuer for the hemisphere.
