Several DC P25 Talkgroups Identified

Thanks to the DC Scanner software-defined radio project, I've been able to identify several new services talkgroups on the DC Project 25 system. Most of these talkgroups have migrated from the Project 16 system over the last several months.

Fairfax County P25 Converting to Phase II

In the coming months, Fairfax County will convert the Project 25 system to allow for Phase II (TDMA) talkgroups. The extra capacity is needed because the users of the Project 16 system will migrate to the P25 system. When the migration is complete, the P16 system will be shut down. The two licenses for the P25 system have been modified recently to add an emission designator for TDMA operation. Having all county users on the P25 system should improve reception for the services users, as the P25 system has more sites than the P16 system (12 versus 8).
