[EAS] Source of the "scary" text in Suffolk Co

[Ed Czarnecki]

I tend to agree that this may be a configuration that doesn't require
additional FCC approval for non-national event codes (i.e. all these codes
allow for transmission anyway up to 15 minutes). 

However, I'm more cautious about national event codes though both NPT and
EAN).  There is a black and white rule on "immediacy" here.  OK, not quite
black and white ... perhaps dark-gray to light-gray...  Would a 2-second,
1-second or less delay be not "immediate" enough?  A rule clarification, as
you suggest, might be desirable in these cases, but hopefully would not
result in a major proceeding.  Again, what is "immediately" upon receipt?
Are a few moments to buffer and now to double check a CAP source allowable?
How many "moments"?

Devices are only required to poll IPAWS for CAP, so we can start there.
I'll be inflammatory here and say I'm a bit less concerned with state CAP
sources as some system, frankly, have been downright undisclosive to some
vendors and preferential to others.  IPAWS is the "universal" CAP bottom
line, and a required monitoring source in Part 11.

>>> Also, cue the debate that IP transmission is unrealiable, and we must
maintain AM Radio for fallback when everything else fails.

Oh, you had to inject that didn't you.  FM radio, AM radio, amateur radio
when all else fails ...  But aside from truly next-gen solutions, it's at
least worth discussing whether the FSK protocol can be enhanced/replaced
with something more efficient, transmitting more data can be transmitted
in-band, with better (or any!) security.  We proposed the TDX protocol, but
that is encountering the expected "not invented here" automated response.
Can we tear something from a MIL-STD / STANAG to chew on as a straw man?
