San Diego and Imperial County Frequencies

San Diego and Imperial Counties share the Regional Communications System, an 800 MHz SmartZone trunking system with both Analog and Digital talkgroups. Most of the county services are on the system, with the exception of CalFire Monte Vista Unit, which is still on VHF with simulcasts on the RCS. San Diego City will soon be combining into the RCS, giving the City and County units greater coverage throughout the area.
