LTR Systems

Latest update 3/27/07. This page is under construction. Check back, or better yet, contribute!

Overview

There are four 900 MHz standard LTR systems on Cape Cod. The Mashpee and Sandwich systems appear to share talkgroups, and I must conclude that it's possible for talkgroups to be used on all four systems. Other systems are in Yarmouth and Brewster. The following tables show frequency and LCN order for each system, and the final table includes heard talkgroups for all three systems with an indication of which system seems to be the "home" for them.

There is a good deal of communications from the MA Military Reservation pollution plume cleanup operation, primarily on the Mashpee but also on the Sandwich system.
