In late October 2006, KALW suffered an antenna malfunction. The station continued to transmit with only three percent of normal power, causing many listeners to think the station had ceased broadcasting, although the audio stream was still available via the website. Fellow public broadcaster KQED-FM allowed KALW the use of their backup transmitter on San Bruno Mountain during the repair process. On November 2, 2006, station general manager Matt Martin posted an update on the station's website explaining the problem and expressing his appreciation to KQED-FM for its technical assistance.
