If only we had a functioning government in this country. Instead, we have a corporate oligarchy and a bunch of fools in Washington who pretend they are in charge of stuff.

Tech question...
Do the rad alts encode a specific signature into their transmissions so that when they receive a signal back, even if on the same freq, it will not get accepted, processed, and counted unless it has the embedded code in it, so as to prevent other signals from interfering? Kind of like a watermark for radio signals.

RADALTS on the same airframe use a frequency offset. De-confliction between aircraft is apparently just based on distance, ie two planes will not be over the MM at the same time, and unrestricted parallel approaches require at least several thousand feet of offset.
Lot's of technical reading here...

This Honeywell guy's analysis seems to indicate that an individual cell phone in the wrong place at the wrong time might have the power to interfere... he says 10mW, and the phones themselves can put out more than that.

-Pai's wiki page
"The FCC is directed by five commissioners appointed by the president of the United States and confirmed by the United States Senate for five-year terms, except when filling an unexpired term. The U.S. president designates one of the commissioners to serve as chairman. No more than three commissioners may be members of the same political party."

Thanks for the link, that looks fascinating, I have added it to my reading queue and will get to it in a few days!
