System Notes
Massachusetts State Police operate two radio systems, an analog trunked system, heard east of the Connecticut River, and Mount Greylock, and a newly implemented digital system, which is slowly growing to cover the entire commonwealth.
Cities like Cambridge, Worcester, Boston, and special systems such as MassPort can only be heard on their respective closest systems
Talkgroups which begin with "6 - - - -" (i.e. 65102), and are five digits, are dynamic talkgroups that are assigned when another linked system's user has connected with the CoMIRS radio system. They are never permanent, despite how frequently they may occur.
