KLSQ (870 AM) is a commercial radio station broadcasting a Regional Mexican format. Licensed to Whitney, Nevada, United States, it primarily serves the Las Vegas area. The station is currently owned by Univision Radio, through licensee Univision Radio Illinois, Inc., and features a simulcast of KISF (Zona MX 103.5).
KLSQ began as KROL in 1986. KROL was founded by "Laughlin Roughrider Broadcasting" and operated from two tower sites. A three-tower operation was built in Laughlin for a 10,000 watt day and 1,000 watt night operation, using two different, three-tower directional antenna system. The other site was near Henderson and was the KROL experimental synchronous transmitter, using a non-directional antenna by day and a three-tower directional system by night. After 840 AM went on in the area, measurements were made showing that a power increase would not cause prohibited overlap with KROL on 870. This allowed an increase to 5,000 watts days (still at 500 watts nights). Both sites used diesel generators to make all of the power to broadcast.
The station was sold to Million Dollar Broadcasting and changed call letters to KOWA, known as "The Cow".
Heftel Broadcasting bought the station in 1995 and changed to a format of Spanish hits.
Management at HBC were concerned that the bulk of population covered by the station was from the second transmitter in the Las Vegas area. This coverage was licensed as a secondary authorization, and was subject to cancellation with little or no prior notice. David Stewart at HBC Engineering found a way to make the northern signal the main (and only site). The city of license was changed from Laughlin to Whitney (which combined some unincorporated Clark County with the former village of East Las Vegas). The former main site in Laughlin was parted out. The Laughlin towers are used by other area stations, including AMs on 1000 and 1490, and, at one time, the analog operation of KMCC TV.
KLSQ has been silent since late 2019. Efforts to ascertain the station's status and ultimate disposition have yielded no information.
On December 12, 2020, KLSQ resumed broadcasting a simulcast with sister station KISF 103.5
