 In 1976, the station flipped back to Top 40, this time as "Magic 93", and with it, a call letter change to KMGK.This was the most successful format to date on the frequency, as the station pulled in good ratings through the late 70s and early 80s.By the mid 80s, KMGK found itself fighting for market share as KRNQ and KLYF began also playing hit music on FM radio.
