City of Cambridge

Cambridge utilizes 800mhz Motorola Type 2 trunking system for Police, Fire & E.M.S. as well as other city services
Sys ID: bb39
Some talkgroups are simulcast to conventional frequencies
Based on information in This Thread it appears that instead of a plain vanilla analog rebanding, Cambridge will begin operating a new P25 trunk system and below you will find this systems frequencies. Also since this is a work in progress we will also show the few confirmed P-25 talk groups that have been discovered. Please note that some P-25 talk groups may or may not be patched full time at present. And as usual any positive input will be welcome.
