Basic Information
This trunked radio system provides communications for the Public Safety services of Loudoun County:
- Loudoun County Sheriff's Office
- Loudoun County Fire and Rescue
- Town of Leesburg Police
Police in the smaller towns in western parts of the county utilize the Loudoun County Sheriff's Office talkgroups. It is also possible that some town police may be using conventional frequencies instead of this system.
Encrypted talkgroups are present on this system. These talkgroups are not able to be decoded with any standard scanner setup. It is believed that the Loudoun County Sheriff's Office utilizes these encrypted talkgroups for Sheriff's Emergency Response Team (SERT) communications, but it is not possible to verify this for certain.
Technical Information
This system has two transmitter sites that are simulcasting the same data on the same frequencies. One site is located in Ashburn, providing coverage for Central and Western Loudoun. The other site is in Sterling, covering the eastern portion of the county, and also possibly providing interoperability with Fairfax County.
This system was rebanded to new frequencies on February 15, 2012.
The control channel is a standard P25 9600bps control channel.
The system utilizes Motorola's X2 TDMA technology, as well as standard P25 Phase I FDMA, for voice encoding. As long as all radios that are associated to a talkgroup are TDMA-capable, TDMA will be used for that talkgroup. As soon as a non-TDMA radio associates, that talkgroup will then be transmitted using FDMA until that radio is no longer associated.
Misc Information
