Maryland Statewide Trunking Interoperability
From The RadioReference Wiki
The State of Maryland appears to have coordinated the implementation of new and upgrading trunked radio systems (especially Project 25 systems) to maintain seamless overlap in talkgroup and 7-digit radio ID numbering. This theoretically allows any talkgroup from a P25 system in Maryland to be patched onto any other P25 system in the state, and for any radio from a Maryland P25 system or coordinated county to talk on any other P25 system without fear of radio ID or talkgroup conflict.
This article serves as a benchmark for identifying new talkgroups and radio IDs based on the current sets in place.
