OHP uses two pairs of low band frequencies state-wide. They call the low band channels sides rather than channels. The cars use one of the frequencies in the pair and the base uses the other. The cars can use the base frequency to talk car to car without the dispatcher receiving the transmissions. You must monitor both frequencies to hear the conversation provided you are in range of the mobile radio.
These frequencies are often linked to a series of VHF and UHF repeaters in the troop area. The mobile relays repeat the cars. The base relays repeat the base. Different troops use different pairs to avoid interference, but any of the sides can be used statewide.
The following is the programming for low band radios in OHP cars:
Side 1 - Receives 44.700, Transmits 44.700 - Car to Car
Side 2 - Receives 44.700, Transmits 44.900 - Car to Base
Side 3 - Receives 45.220, Transmits 45.220 - Car to Car
Side 4 - Receives 45.220, Transmits 45.180 - Car to Base
