History
On April 25, 1975, the station would sign on as KQCR, and aired a Top 40/CHR format branded as "Q103". KQCR became the dominant CHR station in Eastern Iowa; it initially aired automated programming before going live full-time in 1983. In 1994, Rob Norton Jr. and Eliot Keller, owners of KRNA, purchased KQCR to create the Cedar Rapids market's first radio duopoly. On September 5, 1995, KQCR changed its format to country music and its call letters to KXMX, "Max 102.9". The country format lasted almost three years until Norton and Keller agreed to sell KRNA and KXMX to Texas-based Capstar Broadcasting. While the KRNA sale was successful, Capstar terminated the agreement to buy KXMX. Norton and Keller kept the station, changing their format back to Top 40 and the call letters to KZIA on June 12, 1998. Today, KZIA is the only locally owned commercial FM station in the Cedar Rapids market, as most of the commercial FMs in the area are owned by either iHeartMedia or Townsquare Media.On October 31, 2006, KZIA acquired the former KCRG radio from Gazette Communications. KZIA renamed the station KGYM and moved its studios from downtown Cedar Rapids to the KZIA studios on the city's southwest side.
KGYM-AM simulcasts on 102.3 FM. KZIA also airs sports programming on their HD Radio signal, KZIA-HD3. KZIA-HD3 feeds Iowa City translator K292FZ.
Smart FM
The station airs an all-1980s hits format on KZIA-HD2 titled "Smart FM". Originally named "ROBfm" after Norton, and airing an adult hits/classic rock format, it was renamed to "Smart FM" after Norton's death on January 29, 2018, at the age of 69. On August 8, 2020, KZIA-HD2 shifted to all-1980s hits, while retaining the "Smart FM" branding. KZIA-HD2 is also relayed over FM radio through FM translator stations 95.1 K236AA in Cedar Rapids, and 98.5 K253BE in Iowa City. Despite each frequency limited to a low power of 250 watts, the use of two translators allows coverage for both Linn and Johnson counties. The station can also be heard throughout other counties in eastern Iowa via the primary 102.9-HD2 signal through an HD Radio receiver.HD Radio digital channels
On May 14, 2003, KZIA became the first Iowa radio station to broadcast in HD Radio.KZIA initially aired two channels of sports programming on two HD Radio sub-channels. Originally, there was one channel of sports programming on KZIA-HD3, which was just a simulcast of sister station KGYM, but would later split into two channels on the HD3 and HD4 sub-channels. KZIA-HD3 feeds Iowa City translator K292FZ, and KZIA-HD4 fed Cedar Rapids translator K298BM. This allowed up to three different sports programs at once. To designate different frequencies, 106.3 is known as the "South Gym", 107.5 was the "North Gym", and 1600 is the "Main Gym".
In January 2020, KGYM began simulcasting on translator K272GB in Cedar Rapids, and began redirecting listeners to the new frequency. The following month, K298BM/KZIA-HD4 split from the KGYM simulcast and began airing a separate sports talk format as "Gym OT." The schedule consisted of hot talk/male-oriented talk shows and sports betting shows, along with ESPN Radio and SportsMap Radio programming. On January 1, 2022, K298BM/KZIA-HD4 flipped to alternative rock as "X107.5."
