KMYS (channel 35) is a television station licensed to Kerrville, Texas, United States, serving the San Antonio area as a de facto owned-and-operated station of the digital multicast network Roar. It is owned by Deerfield Media, which maintains joint sales and shared services agreements (JSA/SSA) with Sinclair Broadcast Group, owner of dual NBC/CW affiliate WOAI-TV (channel 4) and Fox affiliate KABB (channel 29), for the provision of certain services. The three stations share studios between Babcock Road and Sovereign Drive (off Loop 410) in northwest San Antonio, with administrative offices in an adjacent building west across its parking lot; KMYS's transmitter is located in rural southeastern Bandera County, near Lakehills.

Channel 35 began broadcasting in November 1985 as KRRT, the first independent station serving San Antonio and the first new commercial TV station in the San Antonio market in 28 years. It was owned in part, and eventually entirely, by TVX Broadcast Group, a Virginia-based group of independent stations. KRRT served as San Antonio's first affiliate of Fox when the network launched in 1986. TVX was acquired by Paramount Pictures in two stages between 1989 and 1991.

The Paramount Stations Group sold KRRT in 1994 to Jet Broadcasting of Erie, Pennsylvania. Jet then contracted with River City Broadcasting, owner of KABB, to run the station. The Fox affiliation moved to KABB, which was starting a news department; KRRT then became a UPN affiliate, and it also inherited San Antonio Spurs telecasts from KABB. After River City merged into Sinclair in 1996, KABB and other Sinclair-owned UPN stations switched to The WB in a major group deal that took effect in January 1998. KRRT became KMYS, an affiliate of MyNetworkTV, in 2006; it then became the CW affiliate in 2010, replacing KCWX. In September 2021, the programming that had been airing on KMYS, along with its "CW 35" branding, moved to a subchannel of WOAI-TV; KMYS itself began exclusively airing diginets ahead of conversion to ATSC 3.0.

In December 1980, Hubbard Broadcasting petitioned the Federal Communications Commission (FCC) to add channel 35 to its table of allotments at Kerrville. The commission made the assignment effective January 1982, and three applications were received from Commanche Broadcasting; Hispanic American Broadcasting; and Tierra del Sol Broadcasting Corporation, owner of the recently built KVEO-TV in Brownsville. The commission selected Hispanic American Broadcasting—whose primary owner was communications attorney Raul Robert Tapia—over Commanche Broadcasting, a decision affirmed by the FCC's review board in 1984.

Tapia changed the name of his company to Republic Communications Corporation, for the Republic of Texas, and began building the station as KRRT (for his initials). He sold 49 percent to TVX Broadcast Group, a Virginia-based chain of independent stations, with TVX holding an option to acquire another 31 percent. The station went on the air from studios in San Antonio—located along Loop 410, near Ingram Park Mall, on the northwest side of the city—and a 473.3-meter (1,553 ft) tower near Medina Lake. It was the San Antonio area's first independent station and first new station since KONO-TV (channel 12, now KSAT-TV) signed on in January 1957; it had been the largest city in the country without one, and the only similar outlet was the KENS II cable service. The only UHF station in the market prior to KRRT was Spanish-language KWEX-TV.

The station began broadcasting on November 6, 1985. It affiliated with Fox upon its launch in October 1986; the next month, TVX exercised its option to increase its holdings in KRRT to 80 percent. In 1987, San Antonio got a second independent when KABB began broadcasting on channel 29.

At the same time that TVX was increasing its ownership interest in KRRT, it was also purchasing five independent stations in markets much larger than San Antonio from Taft Broadcasting. The Taft stations purchase left TVX highly leveraged and highly vulnerable. TVX's bankers, Salomon Brothers, provided the financing for the acquisition and in return held more than 60 percent of the company. The company was to pay Salomon Brothers $200 million on January 1, 1988, and missed the first payment deadline, having been unable to lure investors to its junk bonds even before Black Monday. While TVX recapitalized by the end of 1988, Salomon Brothers reached an agreement in principle in January 1989 for Paramount Pictures to acquire options to purchase the investment firm's majority stake. This deal was replaced in September with an outright purchase of 79 percent of TVX for $110 million. That year, TVX attempted to sell KRRT. In 1991, Paramount acquired the remainder of TVX, forming the Paramount Stations Group.

While KRRT never carried a newscast as a Fox affiliate, station management proposed starting a news operation on three separate occasions within the span of two years. Then-general manager Morrie Beitch proposed a 9-minute local news segment to launch January 1, 1991. The planned segment would cut in to a national newscast being planned by Fox at the time, which ultimately did not launch.
