Auxiliary Communications Services

The Auxiliary Communication Services (ACS) for the City of Palo Alto supplements emergency communications with volunteer staff. Both licensed and unlicensed volunteers can serve in one or more functions across administrative, management, technical, or operational areas in our program. If you live or work in Palo Alto and are a communications professional, amateur radio operator, or are interested in learning about radio communications, we welcome your involvement.
As volunteers, hams can:
- Supplement communications at their local neighborhood command post.
- Support communications efforts in the City's emergency operations center or our ESV operations center.
- Assist the operations of our logistic trailers located at our fire stations.
- Serve as mobile communications resources or at fixed locations depending on the needs of the city.
Contact us if you would like to join or to learn more about this program - esv@paloalto.gov.
How To Become An Amateur Radio Operator
Operation of an amateur station requires an amateur operator license from the Federal Communications Commission (FCC). Before receiving a license, you must determine your operator class and pass an examination administered by a team of volunteer examiners. US licenses are good for 10 years before renewal and anyone may hold one, except a representative of a foreign government.
In the US, there are three license classes: Technician, General, and Extra. The Technician class license is the entry-level license of choice for most new ham radio operators. The Technician license requires passing one examination totaling 35 questions on radio theory, regulations, and operating practices. The license gives access to all Amateur Radio frequencies above 30 megahertz allowing communication locally and often also within North America. It allows for some limited privileges, too, on the HF (also called "short wave") bands used for international communications.
Learn about hams and how to become a licensed ham operator. You can also get your ham license in one day when you attend a local ham cram.

Practice & Learning Opportunities (Monday Night Nets and Drills/Exercises)
Palo Alto CERT Net
The purpose of this net is to practice communicating within and between neighborhoods in Palo Alto. This net is organized into five districts, D1 through D5. Every Monday night from 7:15 pm to 7:30 pm, the net runs with separate net control operators and frequencies for each CERT district. The CERT district numbers match the Palo Alto Fire Department station numbers. Join the net closest to you. From 7:30 pm to 8:00 pm, there is a single net for Palo Alto on the main tactical frequency. See the below Palo Alto Frequencies chart for all frequencies.
SPECS Net: Southern Peninsula Emergency Communications System
The Palo Alto and North section of the SPECS net meets at 7:30 pm for early check-ins prior to the main net at 8:00 pm, and following the main net for additional check-ins. There is also time for brief training sessions and announcements of special interest to Palo Alto hams. Visitors are always welcome to check in to the nets. Visit SPECS for details.
