The law is now useless since all cellphones currently in use in the U.S.A. are now digital, so an analog receiver won't receive them in a useful way. It was in April of 1994 that the FCC mandated all manufacturers had to build the radio scanners with a block against scanning any cellular frequencies. The law is now useless since all cellphones currently in use in the U.S.A. are now digital, so an analog receiver won't receive them in a useful way. There isn't a known consumer scanner ever made that can be modified to receive and decipher the current digital cellphones used today. Cell phones today use:Cell phones today use none of which are relevant to the old regulation.*''LTE / EVDO / 4G, 3G, 1x (related terms)''Because there are receivers, such as police scanners, that are not Cellular Blocked, people often wonder how the regulation is being circumvented. Those models that are ''floating around'' are either old, manufactured before the regulation, or new units that are not meant for United States distribution, such as the so called ''export market'', or receivers coming into the country ''under the radar''. It is unlawful for a shop to sell used older model receivers capable of receiving on the blocked frequencies even though there is absolutely nothing to monitor on those frequencies anymore; as stated previously, the cell industry no longer uses [[AMPS]]. HAM radio groups have been requesting the FCC lift the restriction as it is no longer relevant.

Those models that are ''floating around'' are either old, manufactured before the regulation, or new units that are not meant for United States distribution, such as the so called ''export market'', or receivers coming into the country ''under the radar''. There are units manufactured specifically for government use. Government model units will not be cellular blocked.

HAM radio groups have been requesting the FCC lift the restriction as it is no longer relevant. Today the FCC mandate is nothing morethan an annoyance to radio enthusiasts and manufacturers.[[Category:HAM Radio]] [[Category:Radio]][[Category:Law]]
