According to InfoWars the FAA has decreed a no-fly zone to keep news choppers out of the area surrounding the Bundy Ranch.
The "temporary flight restrictions," revealed by a contributor to the Free Republic, bans all air traffic under an altitude of 3,000 feet in the vicinity of the ranch except for aircraft operating under the direction of the Bureau of Land Management.
Seems the BLM really doesn't want people seeing what they're doing out there. Such as driving herds of cattle with helicopters. That's an ugly business.
There are also conflicting reports about cell phone coverage. Some people are saying the service was cut off to the ranch, others are saying it was not. Currently it appears the cell towers are up and functioning (as of last night anyway) so I guess we shall see.
I speculate that if some people were getting no service but others were, or that people could call in from outside the ranch but those at the ranch could not call out, those kind of flaky conditions could be caused by BLM if they had the will to do so. Cell service is 100% under the control of the federal government in the USA (and Canada!) so the cell provider could be doing things to interfere with some phones and not others, or some locations and not others. Furthermore there is lots of equipment that will fit inside a suitcase which can hijack, intercept, jam or otherwise frig with cell service over a limited area and you may be sure the BLM cops have access to such things. If not in their own armory, they can borrow from other services like DHS.
And please, this is speculation. I'm sitting in Southern Ontario, I don't know jack about what they're actually doing. But that's what I'd be doing if I were a power tripping moron with an really big budget.
Tinfoil hatters and doomsday hackers take note, and maybe start working on your own digital shortwave solution to this issue. With enough power a determined individual can bounce a readable signal off the moon, if nothing else. I'm not a radio guy, but I suspect "enough power" would be the output of a couple of diesel electric generators and a decent directional antenna.
Court of last resort, there's always the Apollo laser range finding mirrors, you can bounce a signal off them too. That would be pretty difficult. Very tinfoil hat.
