KRZI is fully simulcast on sister station 1330 KTON Cameron, extending ESPN Central Texas's coverage area into Temple, Killeen, Belton, and Fort Hood.

The associated stations have the broadcast rights for the NFL, the Texas Rangers, The Baylor Bears and NCAA Basketball and Football.

[2] A construction permit for the expanded band station was assigned the call letters KAXY on January 9, 1998.

[3] The FCC's initial policy was that both the original station and its expanded band counterpart could operate simultaneously for up to five years, after which owners would have to turn in one of the two licenses, depending on whether they preferred the new assignment or elected to remain on the original frequency,[2] although this deadline was extended multiple times.

[5] This allowed KEKR 1590 AM Mexia to move farther west in Limestone County, to cover Waco proper with its daytime signal.
