Imperial County, California

Scanner Frequencies & Information (Short Sample)

Below is a short sample of the scanner radio frequency and trunked talkgroup information found in the Southern California Frequency Directory. The book includes thousands more frequencies and talkgroups for this county and all of southern California. The book also includes information on businesses, airports, amateur radio, codes, unit designations and radio identifiers, fire station locations and apparatus, detailed narratives explaining local radio usage and more!

This sample frequency list follows the same general format as found in the book:

[Agency Name]

     [Channel] [Description] [PL Tone] [City] [Receive Frequency or Talkgroup] [Transmit Frequency or Trunked System]

 

 

 

RCS Trunking System (“RC” next to talkgroups)

Most Imperial County public safety agencies have migrated to the Imperial County zone of the larger San Diego County RCS trunking system. The RCS voice network is a Motorola SmartZone 800 MHz trunked radio system. The system uses a 3600-baud control channel data stream and supports mixed mode analog and digital communications, including encryption capabilities.

 

Unlike San Diego County’s large North and South Loops, which transmit on the same set of frequencies from all tower sites in the loop, the Imperial County Zone of the RCS trunking system transmits on different frequencies at each tower location.  As a result, scanner listeners in the Imperial County Zone areas must program a particular tower site (or sites) frequency set(s). Keep in mind that individual talkgroups are only broadcast from a particular tower if system subscriber radios are relying on that tower for their communications on that talkgroup. Generally, monitoring talkgroups associated with the area (such as using the Brawley tower to monitor Brawley PD and using the El Centro tower to monitor El Centro Fire) produce the best scanning results in Imperial County.

 

Note:  800 MHz Rebanding will result in changes to these frequencies. Owners of the book receive free updates with new frequencies at www.Scannerstuff.com.

A Phoenix (AZ) area news media helicopter pilot calls his Scannerstuff book "the scanner bible".

Scannerstuff Publications are relied on by professionals like this news media helicopter pilot/reporter


"Whether you are new to scanning or an oldtimer, there is a lot of meat here to chew on... The ... Southern California Frequency Directory truly picks up where others leave off." --- Larry Van Horn, Assistant Editor, Monitoring Times Magazine.



"What really sets this frequency book apart from most others is the narratives, not only on general radio scanning but on each of the radio systems... This frequency guide goes the extra mile by including detailed maps and narration by those who monitor these frequencies both professionally and as a hobby." Read an independent review of Scannerstuff publications. 

"At the Republic, we use [Scannerstuff books] on a regular basis to track down an obscure agency. Case in point was during the prison standoff last spring. Very helpful!" --- Dave Seibert, staff photographer, Arizona Republic newspaper

"I still say in over 30 years of playing with radios and scanners, this is the best frequency guide I have ever seen."  --- Ron Parks, WB5DYG, Gilbert, AZ"
