Mission Statement

CHRS is 49 years old this year! We are building our new museum at 2152 Central Ave on Alameda Island in the San Francisco Bay. Radio has been a part of most Americans’ lives for more than 100 years. From the earliest experiments with electrical sparks to transmit signals, to the smart phones of today, radio is the cornerstone of all forms of modern wireless communications. Yet few people today know much about the history of this vital technology, much less the pioneers -visionaries like Marconi, De Forest, Charles "Doc" Herrold and David Sarnoff - the men who invented and nurtured radio. The California Historical Radio Society (CHRS) strives to keep this important history alive by creating an environment conducive to sparking interest in radio, in young and old alike. We are filling the information gap between "wireless" in 1899 & "wireless" more than 100 years later.


CHRS is a non-profit, educational 501(c)(3) corporation chartered by the State of California in 1974 to promote the research, restoration, preservation, publication and presentation of early radio and broadcasting. Our goal is to provide a forum for exchanging ideas and information on the history of radio and broadcasting, particularly in the West, with the emphasis on collecting, restoring and displaying vintage equipment, and related materials. We are dedicated to the study of early radio and to the importance of this first wireless medium to the San Francisco Bay Area.

In the early 1970s a group of dedicated people, mostly electronic engineers who were also antique radio collectors, realized that the importance of radio technology and broadcasting history was beginning to fade among the general population. They founded CHRS to preserve and protect the artifacts, ephemera and programs of the radio age. The Society has expanded its AM radio focus to include wireless telegraphy, FM radio, Hi-fi, amateur radio, commercial and military broadcasting, phonographs, television, and other devices used for sound reproduction or transmission. Also, included are the advertising, periodicals and publications relating to radio broadcasting plus the audio air checks and histories of Bay Area radio stations and personalities.

CHRS has nearly 500 members.
