Welcome to the Christchurch Digital Radio System

A network for advocacy organizations, non-profits and hobbyists

The Christchurch Digital Radio System is a project to build a low-cost trunked P25 digital radio network within Christchurch. The network is aimed at advocacy organizations, non-profits and hobbyists to provide a secure communications network within the UHF commercial C-band.

The CDRS provides coverage across all of Christchurch Central, and in the future, all of Canterbury. Radios automatically roam to the best site seamlessly, allowing connected communications outside the range of standard two-way radios
