I still remember those days when I came home from school and I was able to scan cellphone conversations 24/7, IT WAS FUN......All I can say a lot of people cheat each other .
Ohh and all those calls to the 1-900- sex lines WOW so many people calling and the things you heard.Ah, those were the days. I was a kid back then too. I had no idea they would soon go digital or I would have listened a lot more. Most of what I overheard was criminal activities. A lot of anonymous tips got a lot of drug dealers and burglars/thieves in trouble.

There is no regulation against owning or using such a receiver. The regulations are specific to importing and selling them. A later addition to these regulations does address modifying a receiver to receive these frequencies.I just bought a Icom IC-R3 from a guy that didn't know much about it and when I got it today I realize is the IC-R3SS model from japan "Unblocked" what problems could I get into owning this receiver? I know cellphones are digital now. I read somewhere that was illegal to sell them also. I'm confuse.
RTL SDRs are not "scanning receivers" as defined under Commission rules, but instead are marketed as TV receivers. Hobbyist have "hacked" them (in the form of software) to use them as "scanning receivers". However, I think if anyone pushed the issue the FCC might indeed include these devices as scanners or the use of custom software as "modifying" the original use and intent. Since there are no more analogue cell transmissions I think, just my opinion, that there is no pressure to expand the meaning to include such devices.Do any of you realize all of these cheap SDRs (RTL-SDR) being sold now also do not block the cellular range?
Also, in my browsing I've noticed many high end spectrum analyzers do not block the cellular range either.
Something else to note, pager data is in the clear and does not use a freq in the range that is supposed to be blocked.
