New VHF Trunking System

During a recent trip through southern Washington state, I stumbled upon a new VHF P-25 trunking control channel. The frequency was 164.4125 MHz and appeared to be located at the Department of Energy's Hanford Reservation in Richland, Washington.

The control channel showed a System ID "def", WACN of 1 and Tower 101. The system appears to be broadcasting channel numbers instead of actual frequencies. This may indicate that the is an E.F. Johnson trunked system, as has been reported at other DoE facilities.

The system appears to be still in the early stages of being on the air, and no users were monitored while I was watching, but I'll be making some future trips to the area to check on the progress of this system.
