History
Note
While the station broadcasts at 567 kHz, many American radios, especially the digital readout variety, were capable of tuning in AM stations in 10 kHz increments only. Therefore, in the station's marketing, the nearest frequency, either "570" or "57", is used instead. Stations in Guam fall within the jurisdiction of the Geneva Frequency Plan of 1975, instead of the North American Radio Broadcasting Agreement, whose coverage includes the US mainland.
