You have your frequencies, actually, sub frequencies, mixed up Carl.
This is just a dead carrier signal probably with the ESN encoded. You are allowed to listen to it although I can't think of anything more boring except maybe listening to water drip.
Lots of stuff being emitted by that phone other than audio.
Now the equipment itself does have to be licensed but that's just a matter of getting the permit from the FCC.
Most people don't understand the law pertaining to monitoring Cell phones. As long as the equipment is properly licensed you are allowed to monitor all aspects of the call, including the audio. The illegal part is repeating or recording any part of the call.
HAM's and especially scanner people aren't allowed access to everything from DC to daylight. There is a lot of restricted airspace. That's what makes it so much fun getting it.
If you want to have a lot of fun, get the daily encryption key from a tame police radio shop employee and monitor the text. Expensive and illegal equipment but loads of fun. Watch the surplus sales.
Yep! That is the fun of one of my many hobbies!
Thanks for keeping me straight, cause you can see, I have a little attitude about the "blocking" of frequencies.
