 KIOA tried to stay competitive, but with Stauffer Communications' KRNQ coming on air with a top 40 format as well, it was apparent that a change needed to be made soon.In 1976 the decision was made to move the top 40 format to FM as KMGK and for KIOA to switch to an adult contemporary format.KIOA fell to the middle of the pack as far as ratings went and some long term personalities left or took jobs off the air with the station.
