The first nineteen Washington radio stations were born in the fiscal year ending June 30, 1922. This includes KJR, KTW, KMO Tacoma, and KGY Olympia. Louis Wasmer started up KHQ in Seattle, later putting his gear on the back of his motorbike and moving it to Spokane. KDZE Seattle later became KFOA and eventually KOL.
Note the call letters KGB, which existed in Tacoma for a few years, before going dark. The call letters were snagged by a radio station in San Diego.
