WKAQ-FM

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 from 3PM to 6PM, which airs La Tendencia de Molusco, and on 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.

[citation needed] 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.

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.

On May 9, 2022, Hemisphere Media Group, the owners of WAPA-TV, announced they would purchase WKAQ, WKAQ-FM, WUKQ, WUKQ-FM and WYEL from Univision Radio.

During WAPA's 2023 upfront presentation, the network's management alluded that talent from the channel would also be joining the radio stations in the future and vice versa.
