    CHP Callsign letter designations

    I listen to the CHP White Channel which covers the California Central Coast on 42.560 and 460.5500 MHz. Some of the units have letters with their call signs such as 14-3A, 14-3B,14-3C and 14-3S. Does anyone know what the letters in their call signs mean? TIA
