Before you buy a two way radio watch this video.  Many are talking about FRS and GMRS radio use in emergency and disaster service.  If you are a licensed amateur you need to know the legal issues associated with their use and how they effect you. This video may save you and your license from cancellation.

 January will see the beginning of emcom exercises for all radio amateurs in West Contra Costa County, in particular, and anyone able to hit the repeaters, in general.  We're asking 4C’s members to participate and Elmer.  We will also begin a CERT net on the 440 repeater, Saturday mornings from 9 to 10a.

The "Four C's" runs an open repeater located in San Pablo, CA. It is not unusual to get stations checking in from as far east as the Sierras, up north well into Sonoma County and decent coverage throughout San Francisco and the North Bay.
