Beautiful Music
In 1961, it changed call letters again, this time to KODA-FM, airing a beautiful music format. Several months later, 1010 AM KODA went on the air. It operated as a daytimer. The two stations simulcast while KODA 1010 was on the air. KODA-FM continued the station's programming independently from sunset to sunrise, when KODA 1010 was on the air again. KODA-AM-FM and their easy listening sound proved to be quite popular, and enjoyed high ratings through the 1960s and 70s. KODA-AM-FM were sold to Group W Westinghouse Broadcasting in 1978 and was shortly broken up when the AM station was quickly re-sold. The easy listening format continued on KODA-FM, which was renamed KODA when the AM station took new call letters.

Sunny 99.1
The station was sold to SFX Broadcasting in 1989. SFX was amalgamated into AM/FM Inc. and acquired by Clear Channel Communicationsin 1999. By the mid-1990s, KODA had begun adding more vocals to its playlist, and reducing the instrumentals, until it made the transition to soft adult contemporary. The station, which had long been identified as K-O-D-A or "Coda", relabeled itself as "The All-New SUNNY 99.1" in February 1991. The new moniker reflected the evolution from a Soft AC to "Mainstream Adult Contemporary" under the direction of General Manager Dusty Black and Program Director Dave Dillon. Since 2001, between mid-November and December 25th, the station switches formats to all-Christmas music.
