KSQL (99.1 MHz, "Radio Estereo Sol, 98.9 y 99.1") is a Spanish language radio station in Santa Cruz, California. The station simulcasts the signal of KSOL (98.9 MHz) in San Francisco. KSOL and KSQL program a format consisting of regional Mexican music and talk shows. Both stations are owned by Univision. Its studios are in the Financial District of San Francisco, and the KSOL transmitter is in the Los Gatos Mountains.
The 98.9 MHz frequency is the third station in the San Francisco market to use the callsign KSOL. The first was the AM rhythm and blues station at 1450 kHz (the current KEST). The second was a popular soul music station at 107.7 MHz (now known as KSAN). The current KSOL is unrelated to the previous two stations.
The station at 99.1 MHz was, for many years, KLRS ("Colors"), airing an a New Age music format targeting Santa Cruz and San Jose. The station was eventually purchased Viacom The two stations tweaked KOFY's adult album alternative format and adopted the call letters KDBK (98.9 MHz) and KDBQ (99.1 MHz) - "Double 99" in July 1990.
"Star FM" arrived on the two frequencies in Spring 1993, as the call letters KSRY and KSRI were picked up for the stations' hot adult contemporary format.
One year later, the station at 107.7 MHz switched their call letters to KYLD in April 1994, but was already called "WiLD 107" since 1992 as a Rhythmic formatted station. The KSOL call letters were put on then-co-owned 98.9 MHz frequency, with the format was switching to urban adult contemporary. The south signal of 99.1 MHz became a simulcast of "WiLD 107" as KYLZ.
Both KSOL and KYLZ were sold in August 1996. KSOL switched to a Regional Mexican music format, and 99.1 MHz became KZOL, again a simulcast.
In April 2002, KSOL swapped call letters with KEMR (105.7 MHz) in San Jose, and shifted toward a Spanish language adult contemporary approach, with 99.1 MHz becoming KZMR. When 105.7 MHz switched formats and call letters to KVVF, the KSOL call letters returned to 98.9 MHz, with 99.1 MHz redubbed KZOL.
The two station have simulcasted since 1990, with 98.9 MHz covering the north bay, and 99.1 MHz covering the far south bay.
