The station, which had flipped from adult standards on September 14, 2015, originally billed itself as "Z-Rock 105.3" until October 9, 2015, when it changed the moniker to "105.3 Rock Hard" as they can not use the "Z-Rock" branding due to Cumulus Media owning the rights to the name (Cumulus also has stations that compete against the Times-Shamrock outlets in Reno).[6] In 2016, it slightly rebranded as "Z105.3 Rock Hard". On August 1, 2017, KZTI changed its format to regional Mexican, branded as "Radio Lazer". (info taken from stationintel.com)
On August 3, 2023, KZTI changed its format from regional Mexican to Spanish rhythmic, branded as "Kalor 105.3".[7]
On August 15, 2024, at Midnight, KZTI flipped to a rhythmic adult contemporary format as "Jammin 105.3"; the first song under the format was "I Can't Wait" by Nu Shooz. Notably, it marks the first English language format operated by Lazer Media, which focuses primarily on Spanish language formats for their stations.[8]
Booster
In addition to the main station, KZTI is relayed by an FM booster to widen its broadcast area.[9]
