This building in an orchard on the Old Oakland Highway near Wayne Avenue in San Jose housed the transmitter for KEEN (1370 khz.) from 1947 until 1992. Also on the site were two antenna towers used to send out the station’s directional signal.

With a growing need for affordable housing in the area, the City of San Jose’s Housing Department finalized plans to build 246 homes on the site, and KEEN went off the air on December 31, 1992, pending a move to a new transmitter facility. KEEN’s Wayne Avenue facility – building and towers – were torn down shortly thereafter.

In April 1995, the station returned to the air as KKSJ, sharing the transmitter site of KSJX (1500 khz., formerly KXRX) adjacent to the Bayshore Freeway (US 101) near the Union Pacific Railroad overpass and Eggo Way in San Jose. In January 1998, KKSJ became KZSF.
