For more than 85 years, GEARS has been at the heart of amateur radio in Northern California. Based in Chico, we are a community of radio operators of every stripe, from lifelong hams to curious newcomers, brought together by a love of communication, technology, and public service.
All Aspects of Amateur Radio
Local VHF and UHF nets, cross-country contacts on HF, Parks on the Air and Summits on the Air, chasing DX around the globe: GEARS does all of it. We run everything from vintage tube rigs and CW (Morse code) to the latest digital modes like FT8, and we enjoy the full spectrum of radio technology.
We believe in learning by doing, and in sharing what we know. GEARS members mentor newcomers, teach license classes, and help fellow operators explore new modes, antennas, and homebrew projects. Our meetings and events are open, friendly, and full of chances to pick up something new.
When disaster strikes or cell networks go down, amateur radio keeps working. GEARS operators support emergency communications throughout Butte County, and we volunteer at local events too, providing radio coverage for bike rides, charity walks, and community fundraisers that help keep our region connected and safe.
Seasoned operator or brand new, there is a place for you here. Come to a meeting, check into one of our weekly nets, and experience the thrill of making contact, whether it is across town or across the world.

When: 3rd Monday of each month, 7:00 PM (doors open at 6:00 PM)
Where: Chico Public Library, 1108 Sherman Ave, Chico (Google Maps)
Join us for club updates, presentations, project sharing, and good conversation. Meetings are casual and open to all, and visitors and newcomers are always welcome.
Come early, grab a seat, and meet fellow hams from around Butte County.
Membership is $20 per year, due each January. Your dues keep club subscriptions running, help us host events, and keep ham radio alive and well in the North State.
New members join at half price. Send just $10 with your callsign and you are in.
Pick whichever of these three options is easiest:
Losing a loved one is hard, and it can be harder still when they leave behind amateur radio equipment you are not sure what to do with. Our Silent Key Program helps you weigh your options and choose the best path forward, whether that means selling the gear or donating it for a possible tax deduction.
We accept monetary donations three ways. Use whichever is easiest for you.
Our repeaters are open to any licensed operator, but courtesy counts.
Please remember:
Amateur radio runs on respect, learning, and community, and GEARS is proud to reflect those values on every frequency we use.
If you run into repeater issues, have a question, or want to help out with repeater maintenance or the technical team, please email us.
