I have a feeling you are trying to look at a trunked P25 system, if that's the case DSD is not going to decode each channel like it. P25 radios are widely deployed in. Software System Capabilities The built-in mixed mode operation allows you to detect and receive both analog FM and P25 digital modes and to transmit either mode depending on programming. Encryption is simply scrambling the radio transmission so that it cannot be heard, the transmission is then encoded with an encryption key, encryption keys are programmed on radios, matching encryption keys will encrypt the message and the audio will be put back together if the encryption is correct. Many of these frequencies will be part of trunked systems. In this topic, we’ll introduce the P25 standard. com Understand P25, the physical layer and the messages being passed over the air. P25 Radio Systems Training Guide. Current P25 radios do not tie the decryption behavior of their receiver to the encryption behavior of their transmitter.

The P25 CAP Compliance: What Should it Mean to You? document provides definitions for common P25 terminology. Given the fact that the data stream . In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. Older analog systems occasionally used rudimentary scrambling that could be cracked with decoder kits or even monitored by some people that could make it out audibly. The APCO P25 Decoder is an which, upon installation, can be selected from the receiver's Demodulators top bar menu, as simply another alternative demodulator.
