Bureau of Prisons Changes

I have been seeing reports of changes occurring in some of the US Bureau of Prisons (BoP) UHF radio systems in use at federal prison facilities. In some cases some frequencies have been changed, in others the entire system seems to have been replaced.

Most recently I heard from a source in Southern California that the Metropolitan Correctional Center San Diego may have a new radio system going on line. A new Motorola control channel was heard on the air on 408.6125 MHz, with a System ID of F008. Later the control channel moved to 410.0000 MHz with the same System ID.

The original MCC trunked system in San Diego uses these frequencies:
System ID 6426

It would appear that the system is being replaced to conform with the federal UHF 9 MHz channel offset, with repeater outputs being at the low end of the spectrum, and the repeater inputs being +9 MHz.

Also, reports of a new UHF trunked system have been reported on Radio Reference. A control channel has been heard on 406.2125 MHz in the Fresno County area. The control channel is reporting a System ID of EE2B. Not confirmed but the speculation is that it will be used by the new FCI Mendota:
