By day, WTSO is powered at 10,000 watts. But 1070 AM is a clear-channel frequency reserved for Class A station KNX Los Angeles. So at night, to avoid interference, WTSO must reduce its power to 5,000 watts and use a directional antenna with a six-tower array. (WTSO must also protect a former Class A station on 1070 AM in Moncton, New Brunswick, even though it switched to the FM band.) WTSO's transmitter is off East Tower Road in McFarland.
