KGSR (93.3 FM, "Star 93-3") is a radio station licensed to Cedar Park, Texas, and serving the Austin-Round Rock metropolitan area. Owned by Emmis Austin Radio Broadcasting Company — a joint venture of Emmis Communications and Sinclair Communications (not related to television broadcaster Sinclair Broadcast Group, who owns CBS station KEYE-TV) with Emmis as controlling stakeholder, it broadcasts a soft adult contemporary format. KGSR has studios and offices off Interstate 35 in North Austin, and the transmitter site is located off Route 206 in Bertram.[1]

KGSR's effective radiated power is 100,000 watts, the maximum for non-grandfathered FM stations, its signal stretches from Killeen and Temple to the northern suburbs of San Antonio. It has a construction permit from the Federal Communications Commission to reduce its power to 50,000 watts and relocate to a tower in Austin to better cover the city and its suburbs.

KGSR broadcasts in the HD Radio format - its HD2 subchannel broadcasts Austin City Limits Radio, a freeform format inspired by the Austin City Limits television series and music festival. KGSR-HD2 is also broadcast on FM translator 97.1 K246BD in Austin, which was formerly carried on KGSR's main signal prior to its switch to Soft AC. KGSR-HD3 broadcasts No Control Radio, a heavy metal format.


KLEN-FM and KIXS-FM[edit]

The station signed on in August 1961 as KLEN-FM, owned by Highlite Broadcasting.[2] Its original city of license was Killeen, Texas, and it served the Fort Hood area, it broadcast at only 760 watts, a small fraction of its current power. KLEN-FM was co-owned with AM 1050 KLEN (now KRMY); because KLEN was a daytimer, KLEN-FM simulcast its programming by day and allowed listeners to hear the station at night after the AM transmitter had signed off.

In the early 1980s, the two stations switched to a Top 40 format, switching call signs to KIXS and KIXS-FM. In 1986 the two stations were acquired by Duffy Broadcasting which asked the FCC for a major power increase for the FM station.

Top 40 and Smooth Jazz[edit]

In 1986, KIXS-FM upgraded its signal to 100,000 watts, allowing it to "move in" to the more lucrative Austin radio market while still covering Killeen,[3] it relaunched its Top 40 format with the new call sign KBTS "B93." It was an immediate success. But a merger four years later brought B93 into common ownership with competing top 40 station KHFI. So management switched the station to a hot adult contemporary sound as KMMX.

In 1993, the station was bought by LBJ, Inc. for $2.5 million.[4] The company was owned by the family of former President Lyndon Baines Johnson and also owned KLBJ (AM) and KLBJ-FM; the station tried an All-1970s hits format as KHHT.

That was followed in 1996 by KAJZ playing smooth jazz. Two years later, the station tried country music as KLNC.

Rhythmic KXMG and KDHT[edit]

By 2001, the station tried to appeal to Austin's growing Hispanic community with a rhythmic contemporary format as KXMG, known as Mega 93.3. It was also at this time that the city of license changed to Cedar Park.[5]

The stations were part of a larger cluster co-owned by Sinclair Telecable Inc. (d/b/a Sinclair Communications, unrelated to Sinclair Broadcast Group), and Luci Baines Johnson's LBJ Holdings Co.; in 2003, the Indianapolis-based Emmis Communications acquired the LBJ Holdings controlling stake in the stations.[6] KXMG's rhythmic format remained but the call letters were changed to KDHT, and station re-branded as Hot 93.3.

Adult Alternative KGSR[edit]

On November 17, 2009, KDHT began stunting, leading to speculation that it would flip to a talk radio format. However, on November 20, 2009, Emmis revealed that the adult album alternative format heard on 107.1 KGSR in Bastrop would move to the more powerful signal on 93.3. The two stations simulcast for a 10-day period until December 1, when KGSR's former 107.1 FM signal switched to a Regional Mexican music format as KLZT.

On December 13, 2010, KGSR began simulcasting on FM translator K274AX 102.7 FM. This lasted until October 20, 2011, when K274AX switched to a comedy radio format, relaying KGSR-HD3; the comedy format proved to be quite successful in the Austin Arbitron ratings, peaking with a 3.8 share. Its believed to be the highest-rated HD Radio-fed FM translator station in the United States.

On May 30, 2013, K274AX began relaying KLZT-HD2's Spanish-language hits format as Latino 102.7.[7] KGSR-HD3 now airs a heavy metal music format based on sister station 101X's weekly specialty show No Control Radio.

Austin City Limits Radio[edit]

On September 5, 2018, KGSR began promoting a major announcement to come at 5:00 p.m. the following day. At the same time, Sinclair closed on its purchase of translator 97.1 K246BD and began simulcasting KGSR on that frequency.[8]

On September 6, the two stations re-launched as Austin City Limits Radio, co-branded with the Austin City Limits television series and music festival under a multi-year licensing agreement; the station shifted to an "aesthetic" focus on musicians associated with the television series and festival rather than falling within a strictly-defined format, with a broad mix of music that can range from Americana and country music, to alternative and classic rock, as well as contemporary hip-hop music and world music.[9] The first song played under the new branding was Willie Nelson's recording of "Whiskey River"—the first song to be performed on Austin City Limits.[10][11]

Tom Gimbel, general manager of the Austin City Limits program, stated that the new format reflected the listening habits associated with online music streaming platforms, explaining that "people are not tying themselves to Triple A or hip-hop or rock or country. They're all over the map. I think we're going to see a lot of people in Austin listening the same way."[10][11][9]

Star 93.3[edit]

On March 7, 2019, KGSR began running promos directing Austin City Limits Radio listeners to the 97.1 signal. The next day, KGSR flipped to soft adult contemporary as Star 93.3, launching with 9,300 songs in a row. The station targets women 35-54, and carries the syndicated Delilah on evenings; the previous Austin City Limits Radio format continues to air on KGSR-HD2 and the 97.1 translator.[12][13]

In June 2019, Emmis announced that it would sell its stake in the Austin joint venture to Sinclair for $39.3 million. Sinclair will operate the stations under the licensee Waterloo Media.[6]
