WKAQ-FM (104.7 FM, "KQ105 FM") along with its satellite WUKQ-FM (98.7 FM) are a pair of radio stations in Puerto Rico broadcasting a bilingual contemporary hit radio format. Licensed to San Juan, Puerto Rico, WKAQ-FM serves the eastern half of the island while WUKQ-FM, licensed to Mayagüez, Puerto Rico, serves the western half. The stations are currently owned by Univision Radio Puerto Rico Inc., a subsidiary of TelevisaUnivision. The stations are relayed through booster stations, WKAQ-FM1 in Juana Diaz and WKAQ-FM2 in Fajardo, both operating at 104.7 FM, also on WUKQ-FM1  in Ponce, at 98.7 FM. KQ105 FM Radio is best known for its concerts "KQusticos", "KQ Live Concert", "KQ Sunsets", "Uforia Lounge @ The Mall of San Juan", popular hit music playlists, and for its great variety of music including all genres of pop, ballads, few salsa and merengue, and even reggaeton. It's also characterized for having less commercials per hour than any other local station with a programming based only on music 24 hours, 7 days a week, except Saturdays (Sundays repeated) were there is a live Top 20 Countdown involving interviews to artists, presenting the top 20 best  music of the week, and local/international news on artists such as gossips. Also the branding "LA PRIMERA" means that WKAQ-FM was the first FM assigned frequency to San Juan and the second radio station established in the island on October 8, 1958, followed by Rio Piedras's WFID on November of the same year. However, WKAQ-FM became more notorious in 1968 when they started its format of popular music with the logo "LA ESTACIÓN DE LAS ESTRELLAS" and "ESTRELLAS EN ESTÉREO" making noticeable their Stereophonic sound. Later in 1975, WKAQ-FM started broadcasting in quadraphonic sound, using  a Sansui QS encoder and they started promoting it but this experiment didn't last long. In the early 1980s WKAQ-AM turned into news talk radio and the FM changed to Top 40's renamed KQ 105 La Primera until today. WKAQ AM, FM and TV Telemundo were owned and operated by Don Angel Ramos, who also owned the El Mundo newspaper which disappeared years ago.
