101.1 Arroba FM (Hermosillo)

Arroba FM 101.1 (XHVSS-FM) is a radio station in Hermosillo, Sonora, broadcasting on 101.1 FM the @FM contemporary hit radio format of Grupo Radiorama, its owner.

The station traces its history to XEVSS-AM 650, which received its concession on April 25, 1991. Broadcasting from nearby Villa de Seris, XEVSS was owned by Radiorama and aired a grupera format as "Morena 650" with 2.5 kW daytime power. In 2002, the station was leased to Radio S.A., which installed its Radio 13 news/talk format, featuring programming from XEDA-AM in Mexico City.

In 2011, XEVSS was approved to migrate to FM, and XHVSS-FM 101.1 came on air the next year under the operation of Grupo Larsa Comunicaciones with a pop format known as Sin Límites. In early 2014, it changed to romantic music as Romántica 101.1; that format lasted four years, until August 2018, when it flipped to grupera under the La Más Chingona name.

The entire La Más Chingona format and intellectual unit moved to Larsa-operated XHHER-FM on July 31, 2019; days later, XHVSS became La Ke Buena ahead of operation by ISA Multimedia. ISA Multimedia ceased operations of its Hermosillo cluster on December 31, 2021. On January 15, 2022, the station switched to the Arroba FM format from Radiorama itself; that same day, XHESON-FM became La Poderosa.
