106.7 FM signed the air on June 19, 1962 as KLZ-FM. Initially airing a simulcast of their then-AM sister station, it flipped to a rock format in the early 1970s. In 1977, KLZ-FM changed their call letters to KAZY (now at 93.7 FM in Cheyenne, Wyoming) and continued with a rock format until April 20, 1994, when KBPI took over the 106.7 frequency, moving from 105.9 (now KALC).
In December 2017, iHeartMedia robbed KBPI of its signal and re-aligned multiple stations in the Denver, Colorado Springs, Fort Collins, and Cheyenne markets in order to form an inadequate trimulcast (which was later split up on Jan. 28, 2019) of KBPI on the 107.9 frequency. To facilitate the move for the main signal, on the 1st, KYWY (an adult contemporary station in Cheyenne, Wyoming, which was acquired by iHeart in 2016) moved its existing format to an HD Radio subchannel of KOLT-FM and its analog translator on 97.1, allowing KPAW to move its classic rock format and call letters to the 92.9 signal four days later. On the 11th, KBPI then moved its format and call letters to KPAW and translator K300CP, while also adding a simulcast on KBPL. The KYWY calls were warehoused on the former 106.7 signal; iHeart stated that the station would temporarily simulcast KBPI through the end of the year, and be re-launched with a new format after the end of the simulcast period.
On December 18, 2017, at 5 p.m., KYWY dropped out of the simulcast and flipped to country music as 106.7 The Bull, launching with a 10,000 song commercial-free marathon. The flip gave long-time country stalwart KYGO its first full-market competition since that station flipped to the format in 1979, while also competing with KWOF, which rimshots the market from the north (KWOF has since changed formats to sports talk, likely due to the launch of "The Bull"). On December 26, 2017, KYWY changed its call letters to KWBL to match its new branding.
