can someone tell me how to pick up on cell phone conversations with a trunking scanner?

Answer 1

it's not right to listen to others conversations.

Answer 2

What you are trying to do is a federal crime. It is illegal to intercept and record cell phone conversations to which you are not a party.

CDMA phones are encrypted qith a 16 bit encryption code that is unique to each phone call, and changes several times a second.
Carriers like Sprint and Verizon are less susceptible to this kind of crime.

Answer 3

You can't anymore, its all digital, no more analog phones out there, unless you collect old stuff!!!!
