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.

2017 CEV Frequency Plan for San Joaquin County

How-To Use the Plan — This is an expanded version of the text below, including an added repeater map and detailed information about channels 1-20 and important local repeaters.

How to Use the CEV San Joaquin County Frequency Plan

Now in its tenth edition, the CEV frequency plan is a guide for programming Amateur Radio equipment in San Joaquin County. By following the plan, in an emergency everyone will have the same frequency with the same name on the same channel in every radio.

The plan is divided into five sections, only the second of which is required to be “plan compliant.” The other four sections exist for convenience and completeness but should be programmed whenever possible.

The plan seeks to define memory channel numbers and memory channel display names, giving everyone a common way to describe repeater and simplex channels that might be used for emergency communication. Particularly, this avoids new hams needing to program channels “on the fly” after an emergency has occurred.

This is a dual-band frequency plan. In VHF-only radios, the UHF channels should be programmed “empty” to preserve channel number compliance with the plan.

The sections are:

1 — Channels 1-20 — User Option

The first 20 channels are intended for the user to program as he or she prefers, keeping favorite and/or most-used channels easy to access. The plan does include suggestions for these channels, basically a repeat of Section 2’a “Core Channels” but with friendly names replacing the tactical names used for Channels 21-40.

2 — Channels 21-50 — Core Channels

These channels represent the core of the plan and include 18 repeaters, NOAA weather and simplex channels, all with tactical identifiers as channel names. All of these are open repeaters, available for all Amateurs to use. Not that channels 1-20 are, essentially, these same channels  (21-40) with friendly names, making it easier to find the repeater you are looking for.

NOAA Weather Radio is Channel 50.

3 — Channels 51-70 — Regional Channels

Includes repeaters used in other counties that might be used when working with Amateurs in those areas.

4 — Channels 71-80 — Packet Radio Channels

Here for completeness for radios also used to packet data communications.

5 — Channels 81-109 — Simplex Channels and Version Marker (Channel 109)

Includes every VHF simplex channel in the ARRL band plan. Channel 109 is a marker showing the version number of the frequency plan programmed into a particular radio.

For convenience in radios with hundreds of channels, the plan might be programmed to start at channel 101, 201, etc. to free the first channels for other uses.

In radios where the highest memory channel can be reached by turning “backward” from channel 1, some program common scanner frequencies into the highest memory channels. Start with scanner channel 1 in memory 999, scanner channel 2 in 998, etc. Make it easy to turn common public safety or other memory channels.

If the radio is capable of transmitting outside the ham bands, make sure the transmit frequency for these non-ham memory channels is a vacant ham frequency (where you can transmit legally). Avoids unintentional interference to non-ham users. Likewise, don’t enter transmit PL tones on non-ham memory channels unless you are authorized to transmit on them.
