KMIY (97.1 FM) is a hot adult contemporary radio station that is licensed to Green Valley, Arizona and serves Tucson, Arizona. It is owned by iHeartMedia (formerly Clear Channel Communications).

KMIY broadcasts from the iHeartMedia studios in midtown Tucson, but their transmitter is located slightly northwest of Green Valley. Because of the low ERP, and the transmitter location, the station is extremely hard to pick up in most northern suburbs such as Flowing Wells, Avra Valley, Oro Valley and Marana, but is easy to pick up in central and southern Tucson.


Starting in the early 1990s, KGMS was a Christian CHR station that played new Christian pop, rock, and even dance songs in the mix. This format seemed to last the longest.

In 2001, it became Cool FM - KWFM-FM, an oldies station. KWFM originally was on 92.9, but was moved to 97.1 to make way for Clear Channel's Coyote Country. Problems with signal reception across the city were evident. Plans to move the station's license to Tucson and increase ERP never went through, leaving poor ratings for Cool FM.

In 2003, KWFM was moved to AM, which opened the door for KTZR-FM, a Spanish-language station. This has so far proven to have little success, with ratings for the station being anywhere from 15th to 20th place in the Arbitron ratings.

On November 28, 2011, KTZR-FM changed their format to a simulcast of news/talk KNST 790 AM under new calls, KNST-FM.[1][2]

On February 14, 2013, KNST-FM changed their format to country as "Wild Country 97.1".[3] A week later, the call sign changed to KYWD.

On December 18, 2015, KYWD rebranded as "97.1 The Bull".

On January 6, 2021, at 9:29 a.m., KYWD's country format moved to the stronger 92.9 FM frequency as part of a format swap. KYWD picked up KMIY's former Hot AC format, now branded as "My 97.1".[4] The KMIY call sign moved to the 97.1 frequency on March 29.
