Also in the late 1990s, the station was moved to a new transmitter site at the top of the Big Horn Mountains and the power was increased to 75,000 Watts.

This allowed the station to cover a large portion of Northeast Wyoming, including most of Sheridan, Johnson and Campbell counties.

Most of the programming on KZWY remained locally generated, but some nationally syndicated weekend shows were added including The Beatle Years, Flashback, The House of Hair, The Tour Bus and Harddrive.

Initially, a heavier rock format called "Nitro" was aired on the HD-2 channel and ESPN Radio on HD-3.

K290BL and K290BM both rebroadcast KZWY's HD-2 programming, which is branded as "Oldies 105.9" to reflect the dial position of the translators on which it appears.
