Sandy's CB Shop in Nisku Will do cell mods for $32.00 + tax.

Hey guys

Is there action on cellular anymore since they change to digital? Have not listened for the longest time. It actually became pretty boring when I had my pro-2006.

Take care

Here in the good 'ol U.S.A. we're not legally allowed to monitor cell phones but....... if we were allowed to I would guess that most cell users now have digital phones. I would wager that there aren't any receivers/scanners on the market, to the average consumer anyway, that will demodulate a digital cell call.

I may be wrong on this and feel free to correct me if I am, but dual mode cell phones often switch back to analog for various reasons. I have a Yupi scanner for work purposes and on the rare occaisions that I scan the cellular frequencies I often hear short bits of voice followed by a burst of noise and silence.

Someone told me recently that this is the sound of a dual mode phone switching back and forth from analog to digital.

Dual mode phones will switch back and forth but the amount of time spent on analog is pretty low.

I would say that getting a scanner cell modified these days is probably a waste of money unless you do it yourself. The amount of analog channels left on the air is very low compared to previous years.

Ya thats what I mean. I think pretty soon we will see the analog thing pretty much history

Take care

Here's a few things that may clear up digital cellphone questions:

1) - Dual or TriMode phones that have analog only switch to analog in 2 rare cases:
A- When Roaming off your home network AND the roaming partner company is not digitally compatible. (Example, a GSM or TDMA customer roaming on a parter company that only offers CDMA digital, the phone would revert to analog if available).
b - Extreme fringe areas. People out west in Yellowstone ect, often report that the analog signal travels a bit farther than the digital, when you lose dig service, the phone will lock onto a noisy but usable analog signal for a couple more miles...

2) - Digital cellphone transmissions are nothing like APCO Scanner transmissions.
A CDMA Digital phone signal (Verizon, Sprint, Alltel), chops up your call into millions of fraction of a second "bits", & spreads them across a 1.25Mhz Wide patch of frequencies simultaneously. This is equal to a couple of hundred or more "scanner" frequencies". There isn't "1" discrete "frequency" that you could type into a current scanner , to even hear the digital noise!
GSM/TDMA/Nextel are similar, they use a system where there could be anywhere from 2 to 10 or more different digital cell call "parts", on any given frequency every fraction of a second, & there can be pieces of digital information spread across multiple channels.
There is Nothing inside a current Bearcat Or Radio Shack scanner that is capable of receiving, or decoding these complex signals. You could cut every resistor & diode in the radio or Apco card, & that still wouldn't re-materialize the scanner into a CDMA/ or GSM digital decoder receiver.
