XHXW-FM

XHXW-FM is a radio station on 90.3 FM in Nogales, Sonora, Mexico.

It is owned by Grupo Audiorama Comunicaciones and is known as KY (pronounced like "calle") with a variety format.

Roque Chávez Castro received the concession for XEXW on January 21, 1955; it signed on nearly three months later, on April 11.

Eventually, XEXW became a Radiorama-owned station and was spun off to Larsa when Radiorama exited many Sonora markets.

On May 10, 2019, XEXW became the last AM station in Nogales to move to FM as XHXW-FM 90.3, changing to the La Más Chingona brand already used by Larsa in Hermosillo and Ciudad Obregón.
