Newer scanners cannot be modified, but many others can be modified to
receive the cellular band. It is also possible to buy an unblocked model of
just about any scanner that is intended for international sale by ordering
it from another country (www.bander.com is one such source). This is, of
course, illegal, but still quite possible.

Older scanners may be able to receive cell images on frequencies that are
+/- 21.4 MHz (2 times the IF) away from the cell frequencies. This is
usually more difficult with triple conversion scanners.

Not all cell phones are digital (yet). Somewhere I read that the OnStar
system utilizes analog transmissions...this may depend on the area. There
is always some analog activity in the cell bands, but it tends to be quite
uninteresting, and in many cases, only one side of the conversation can be
heard (this, too, depends on the area). Most cell phone activity is
digital, however, and it will continue to go in that direction. Eventually,
blocking a scanner will have no purpose.

Can you receive cellular phone calls on a modified scanner? I thought
with all phone being digital now you could not?

I noticed a few years back that there was a push to get cellular operations
off of 800 Mhz in the US and 900 Mhz in Europe. Basically everything was
being shifted to 1800 and 1900 Mhz. In doing some research, I have came
across the overall plans. Look on a web site for UMTS (universal mobile
telecommunications service). This was all decided in 1998 at a World Radio
Conference. The web site is http://www.umtsworld.com. Look at the FAQ for
overall plans to shift, it lists just about every Cell phone system in the
world. The Technical section lists the frequencies (1800 to 2200 Mhz). It
will not only be a phone system but a computer network and TV service
provider. It also has a satellite phone component as well.

The police want cell phones off of 800 Mhz. And they want 700 Mhz for data
(MDT).

BTW, Verizon just purchased Direct TV and SBC (Cingular) purchased Dish
Network.

The laws will need to be updated.

I have a Bearcat 200 XLT scanner which can receive analog cellular from all
the surrounding cellsites. People seem to be still hanging on to their
analog cell phones. The number of conversations has dropped due to digital
cellphones but analog isn't dead yet. I can also hear conversations on my
Ericcson cellphone when I put it into field test mode and enter the proper
code.

Why?


For the same reason you asked the question and a dog licks his
testicles.
