San Diego and Imperial
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.
