NC6MC is the call sign used for McARCS official communications.


The Mendocino County Amateur Radio Communications Service (McARCS) is the support organization for amateur radio emergency communications in Mendocino County – about halfway between San Francisco and Eureka between the Pacific Coast and halfway to the central valley.

This service is made up of FCC-licensed amateur radio operators who have volunteered their time and resources to serve the community in times of emergency. They maintain reliable radio systems that do not depend upon regular sources of electric power, and are prepared to respond to the need for radio communications whenever regular systems fail or are overloaded, including such emergency conditions as fire, flood, toxic spill, earthquake, or other disaster.
