DWLS (97.1 FM), broadcasting as Barangay LS 97.1, is a radio station owned and operated by GMA Network.

Culiat, Tandang Sora, Quezon City and 23 Sumulung Highway, Barangay Santa Cruz, Antipolo, Rizal.

In 1972, DZXX temporarily shut down due to Martial Law, later it was revived under the label DZXX/DWXX 1000 (Double X) when Hypersonic Broadcasting Corporation owned this station.

In July 1976, GMA launched its third radio station 97.1 WLS FM, airing adult standards and jazz music.

"The Triggerman," which was first heard on Kiss FM 101.1 (now 101.1 Yes FM), where the top 20 songs of the day were counted down in the mold of BBC Radio 1's The Official Chart Show at noontime, and "Campus Aircheck", an institution of sorts for aspiring DJs to get hired by Campus Radio, touted as "the first school on the air".

With consistently low sales figures, this paved the way for Mike Enriquez to successfully persuade the network's upper management to agree to shift WLS to a seemingly more profitable "masa" format.

Unfortunately, the industry reception is lukewarm and Barangay LS has yet to regain the revenue losses incurred by the shift of advertisers to competing FM stations.

That same day, almost all of the staff who were also from the former Campus Radio format, and after years of loyal service to GMA Network, were summarily dismissed by Mike Enriquez.

Ken Chan and Rita Daniela performed its station's new jingle entitled Tayo ay Forever under GMA Music.
