SO...what you are saying is that if Obama should try something like martial law and taking over the airwaves or refusing to step down as President should he lose....the true patriots(FReepers and others) need to move immediately to take over every television station that we can?
(half joking)
Absolutely!

I just know that EAS units in cable provider headends only react to the alert triggers they are configured for. The newer models receive the trigger and either output a tone and crawl across the bottom of the screen or force tune the digital set top boxes to a specific EIA channel. That is the EIA channel on which the actual message will be broadcast (say channel 3). On cable plant there are two basic formats used for delivery, RF QAM (pronounced kwam) and IP. The simple disconnection of a coax cable or an Ethernet cable will prevent the EAS from broadcasting to the plant.
Over-the-Air broadcasters and radio stations have different requirements. I don’t work in those facilities so I can’t speak to how their EAS system is set up. My comments pertain only to cable operators.
P.S.
This link is an example of a state EAS plan.
It is for the State of Wisconsin

It is representative of how every state is set up for EAS alerts.
