competition from newcomers such as KTYL-FM and KPXI, as well as other AM Top 40s in the area such as KLUE in Longview. KDOK throws in the towel; becomes Standards KYZS On New Years Day 1990, the heritage KDOK Top 40/Contemporary Hit Radio format was finally dropped from 1490, reformatting with Big Band and Adult Standards music. The current KYZS call set was granted on February 1, 1990. 1490 drops music; becomes talk The Standards format would continue on with meager success until 1993, when KYZS dropped music altogether, eliminating the C-QUAM AM stereo broadcast in the process, and remained a spoken word format for the next 29 years. Formats included talk radio and sports radio, both in English and Spanish. Paul Gleiser, d.b.a. Gleiser Broadcasting, L.P. purchased the facility on April 23, 1998. On November 22, 2021, an application for license reassignment was filed with the Federal Communications Commission to transfer KYZS and its FM relay translator K239CB from ATW Media to Chalk Hill Communications, LLC. of Kilgore, Texas. Chalk Hill owns and operates Soft Adult Contemporary 100.3 KZQX and Classic hits 1240 KDOK in the Longview portion of the measured Tyler-Longview market. Chalk Hill also operates a 250 watt FM translator from the CBS 19 tower in southeast Tyler, on 97.9 FM, a rebroadcast of KZQX "QX-FM". The deal was consummated and filed with the Federal Communications Commission on January 31, 2022, giving Chalk Hill Communications stewardship of both the oldest and the third oldest continuously operating AM stations in East Texas. Return to K-DOK With the purchase of KYZS and its FM translator finalized, ESPN Radio's sports programming was discontinued on the same day, as the station moved to a direct simulcast of its new AM sister station in Kilgore. The programming change marked the return of the legacy K-DOK branding in Tyler, with 1490 now broadcasting many of the same songs and artists that it aired in its heyday, and marking the first time a secular music format has been broadcast from the AM signal since 1993. 95.7 K239CB is broadcasting a music format in stereo for the first time, having signed on in mono with "ESPN Deportes Radio", and then transitioning to the primary ESPN Radio feed in conjunction with its AM primary.
