Radio Repeater Network

May contain: electrical device, utility pole, and antenna
Cosumnes Repeater on Mount Aukum. Huge thanks to Kehret Vineyards for the use of their property.

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.
