What kind of digital phone do you have that switches to analog?

well I guess thats what its doing. its made by LG and we are on ATT. When it
has a digital signal it displays a D in the corner and then here it says
finding and the D goes off and the signal goes way up.

CDMA is just a type of digital - just because a phone is CDMA doesn't
necessarily mean it is going have AMPS. Most cellphones sold these days are
either dual-mode (digital(cdma-or-TDMA)/AMPS) or
tri-mode(digital(cdma-or-TDMA)/PCS/AMPS)

As far as switching to analog in rural areas this is my point its possible
your carrier only covers it by a roaming agreement with another carrier by
the usage of amps since the digital technologies don't match

I have found that in sparse areas I prefer analog to digital cause I know
when I'm going to get dropped by the amount of static vs the silence

CDMA phones will, they are dual mode.

So yes, people advertsing their scanners as UNBLOCKED !!!!! are really saying
very little in practice - The only good reason to pay a premium to get one
would be to bank on the possibility that some other service of interest will
eventually move into this frequency region.


That's not entirely true. Take Icom, and Yaesu, for example. When they
block out the cellular portion fo the spectrum, they block out
additional bandwidth below, and above the frequencies that the FCC
requires them to omit. So you may not be able to monitor perfectly
legal trunked systems, because they fall into this blocked-overlap, so
to speak. In addition to that , many radios have to block portions of
the spectrum that are in an entirely different band, due to the
possibility of receiving cellular images. So you end up with a very
crippled radio!

Well ... I guess its only crippled insofar as theres anything in the
blocked portions worth listening to - And if Icom ect are dumb enough to
block legit portions, then I simply would not purchase one.
As far as blocking possible mirror freqs, I imagine they would be in the
700-900 range, and as such not much of a sacrifice.
I thought the law was stupid when first enacted, and haven't changed that
opinion.
The responsibility to ensure private comms should have rested exclusively
with cell phone providers - And as we all know, anyone with half a notion
could listen to them nonetheless.
I've learned to live with the ban though, and even though I have radios
perfectly capable of receiving blocked bands, I never do - And would not
pay much of a premium for a scanner that is unblocked ... Except, like I
said, as a hedge against someday a service of interest moving to these
bands.

: 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.

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