KPBS-FM interference problem in Santa Barbara
In parts of the Santa Barbara area sometimes during atmospheric ducting co-channel KPBS-FM in San Diego can override or interfere with the KSBX signal. At one time KSBX was a 9 watt translator on 89.9 MHz. Another station is now using that translator. A deal was worked out that would vacate that frequency. In 2006 KCBX filed an application for a U.S. Federal Communications Commission (FCC) construction permit to move back to 89.9 MHz and increase the effective radiated power from 50 watts to 350 watts. Part of the application were copies of numerous letters and emails from listeners complaining about the signal override or interference from KPBS. In support of the frequency change a consulting broadcast engineer was hired to analyze the situation, make signal strength measurements during ducting and fully explain the technical causes of the problem to the FCC. The KPBS signal travels completely over water, which makes the problem worse.
In 2010 KPBS was granted a construction permit to increase its effective radiated power from 2,700 watts to 26,000 watts. The consulting engineer explained to the FCC that if the frequency change was not granted this would make the already bad situation even worse. In February 2012 the FCC dismissed the construction permit application from KCBX. KPBS started broadcasting with the new 26,000 watt signal on October 1, 2012.
