Opinions expressed are my own. I hope they are useful, but policies and procedures vary widely from one location and group to another.

What I describe may not work for you and may even be unsafe. Always follow your local policies and procedures!

Also, unless specifically mentioned, this site is about VHF/UHF operations and not HF, which is very often different for very good reasons.

Emergency Communications Overview

Amateur Radio emergency communications in San Joaquin County is organized in multiple ways. There is no longer an ARES group in the county, it’s function has been taken over by California Emergency Volunteers, a not-for-profit founded by N5FDL and others.

CEVOL works with county agencies, hospitals, clinics and other organizations to provide for their emergency communications needs. The group also works with Ripon Fire and the County’s Joint Radio Users Group, comprised of all fire departments in the county except Stockton, Lodi and Manteca.

The group also installs and maintains multiple repeater systems, with the ultimate goal of providing handie-talkie coverage on at least one repeater everywhere in the county. CEVOL also organizes HamCram licensing events and will offers the Oregon ACES emcomm training in Northern California.

Frequency Planning

CEVOL also developers and manages the official Amateur Radio EMCOMM Frequency List for San Joaquin County. It includes repeaters and simplex channels likely to be used during an emergency, providing a standardized name and memory channel for each. Copies of the frequency list, as well as radio programming files, are available on this site.

All Amateurs are encouraged to include this frequency plan in their radios. To make that easier, the plan makes channels 1-20 “user option,” encouraging users to program those channels as they see fit.
