There was an article in a past issue of QST Magazine telling the story of the HAMS that works for the NFL during the Super Bowl, ensuring that there is no illegal transmitters inside of the stadium.
All different kinds of snooping devices used to discover non authorized RF.
Everything from wireless microphones to the helmet radios are all coordinated.
Non coordinated devices are immediately confiscated.
I doubt if they will get a fine, because as long as it is non encrypted, the frequency used wouldn't change and the NFL already has the frequencies used and the type of encryption.
It is just another way to generate media hype to get the morons to follow the news so as to generate more interest, since it has been reported that Thursday Night Football is not coming back next year due to low ratings.
Actually their ratings would be higher, had it not been moved to The NFL Network, which only comes with a Premium Cable Package!
