KGUM (567 AM) is a radio station licensed to serve the community of Hagåtña, Guam.

Owned by Sorensen Media Group, it broadcasts a news/talk format branded as News Talk K57. Although KGUM broadcasts on 567 kHz, most U.S. radios tune in 10 kHz increments only; the station has thus marketed itself as being on the next nearest frequency, 570. Stations in Guam fall within the jurisdiction of the Geneva Frequency Plan of 1975, instead of the North American Regional Broadcasting Agreement used in the U.S. mainland and Hawaii.

KGUM's sister stations include FM stations KZGZ and KGUM-FM, TV stations KTGM and KEQI-LD, and additional stations in the Northern Mariana Islands.

History[edit]

KATB went on the air in February 1975. It was owned by Magof, Inc., a company of A. T. Bordallo. Bordallo died in 1977, and the station was transferred to his estate. K-57 Radio bought the station in 1981, relaunching it as K57 Radio with the new callsign of KGUM. Four years later, KGUM began using the name News Talk K57.

In 1992, KGUM began broadcasting with 10,000 watts.

A storm knocked down KGUM's tower in January 2016, requiring the station to broadcast under special temporary authority with 5,000 watts.

On October 12, 2023, Sorensen Media Group opted to sell the station to Glimpse Media, and after a lot of speculation about the station's future. On the next day, radio station signed off together with sister stations KGUM-FM, KZGU and KZGZ, due to a format changes.

Programming[edit]
