[3] KSSK serves as Hawaii's primary AM station entry point for the Emergency Alert System, with KRTR-FM providing PEP capabilities on FM.

KSSK-AM-FM use the slogan "Hawaii's Favorite", and Nielsen consistently ranks the pair as Honolulu's most listened-to radio station.

Unlike most other Adult Contemporary stations in the mainland US, KSSK adds local artists in addition to the usual format.

[9] Prior to the December 7, 1941 attack on Pearl Harbor, KGMB was asked to broadcast music in order to provide long-range guidance to a flight of Boeing B-17 Flying Fortresses on their way to Hawaii from the mainland.

During the attack, KGMB dispatched reports to CBS Radio, which in turn were cited on-air by John Charles Daly, who anchored the network's coverage of that day's news.

During these days as KGMB, the longtime jingle One of the Good Things about Hawaii is Wonderful was first heard on the radio as early as the 60s before former sister station KGMB-TV adopted it for television and campaign use.

[10] At the time, KSSK was the market's #1 station and the new owners wanted to capitalize on that success, especially as music listening was shifting to FM.
