  • Introduction to P25 Encryption | Tait Radio Academy

    Although analog encryption is possible, this typically degrades the audio quality and also results in a reduced coverage area, as stronger RF signals are needed to clearly receive the encrypted calls. One of the key benefits of P25 Digital Radio over analog radio is the ability to securely encrypt calls without impacting the coverage area. they are trunked but they are digital --and around here only the state police and either Motorola or Harris whomever built the system know the encoding algorithm. So essentially they are encrypted but its more like trying to listen to a nextel radio or digital phone signal on an analog scanner.

    What is encoding and decoding? - Definition from WhatIs.com

    Encoding is the process of putting a sequence of characters (letters, numbers, punctuation, and certain symbols) into a specialized digital format for efficient transmission or transfer. Decoding is the opposite process -- the conversion of a digital signal into a sequence of characters. Encoding and decoding are used in data communications, networking, and storage. Project 25 (P25 or APCO-25) is a suite of standards for digital mobile radio communications designed for use by public safety organizations in North America.P25 radios are a direct replacement for analog UHF (typically FM) radios, but add the ability to transfer data as well as voice, allowing for more natural implementations of encryption and text messaging.
