-OP25 is a project to bring together folks that are interested in implementing APCO P25 using a software-defined radio. Our goal is to build a software-defined P25 analyzer that is available under the GNU Public License (GPL).
+APCO P25 is the digital communications standard used by many police and emergency services throughout the world. Most notably the US, Canada and Australia deploy systems based on P25. Compared to existing analogue systems P25 offers improved spectrum use, coverage and flexibility. Provision is made to ensure the confidentiality of traffic, to allow the use of trunking and the provision of data in addition to voice services.

 Although hardware scanners such as the Uniden BCD996T offer APCO P25 functionality a software radio offers reduced costs and improved flexibility. For example, software radios can receive many channels at once, handle both voice and data (including the trunking control channel), decrypt encrypted traffic when the key is known and log traffic to disk for later analysis. With the right software a software radio is, therefore, a powerful analysis tool for debugging and monitoring of P25 networks.
