Installation of the high power RF switchgear and testing of the new transmitter is complete. The auxiliary transmitter is now installed in the main building. The project is basically finished, although work will continue for the next few months on the remaining details. KPFK was restored to full power operation at 8:20 PM, July 11, 2002.
