Radio Repeater Network
CERA and the El Dorado County Amateur Radio Club maintain one of the most extensive and robust Radio Repeater Networks in California, with virtually 100% coverage throughout El Dorado County.
Repeaters make it possible to extend radio signals so communities spread across hundreds of square miles can talk to each other which is especially important in the hilly terrain of the foothills.
We are continuously working to improve our coverage areas and fixing and upgrading repeater stations, antennas, towers, and other equipment as issues are reported.
Setting up and maintaining the repeaters is by far CERA's biggest expense. We appreciate any donations from the community to help with these expenses.

The following repeaters are available in El Dorado County but are not directly supported by CERA or EDCARC.

| 146.805 | -0.6 | 123.0 | Also known as "the 805" repeater or KA6GWY which is the call sign for Frank Yost who set up this high-level repeater, primarily for use by El Dorado County Sheriff's Office for Search and Rescue. Other Amateur Radio Operators (HAMs) can use the repeater. The repeater is also used by Rubicon Trail enthusiasts who become licensed HAMs so they can communicate and stay safe in this isolated, remote, rugged area that has no cell service. |
