 The 92.1 FM frequency signed on the air in September 1983 with a CHR format as KZRQ "Z92".The station, which was only a 1,400-watt at 300-foot Class A, took heavy shots against its CHR neighbor on the dial, KKBQ-FM "93FM" (which is a 100,000-watt Class C at 2,000 feet) and even had a song parody of then hit, Ray Parker Jr's "Ghostbusters" called "Zoobusters" that poked fun of KKBQ-FM's Q-Zoo morning show.The station also claimed to be the first station to play CDs and the world's first all-digital station.
