KQIZ-FM 93.1 shifted from CHR "Z93" to "93-1 the Beat" in 2000
KQIZ went on the air around Thanksgiving, 1976. Very slick AC format at the time, which they screwed up after only two or three years.
96.9 was AC KLSF until it became country KMML-FM in 1993 (picked up from 98.7). KMML-FM flipped to CHR "Kiss" in 2007, and taking the current KXSS-FM calls in 2008.
96.9 went on the air in the Spring of 1985, with an AC format very similar to what KQIZ had once run.
98.7 also has had a fair number of formats. It changed from country KMML to hot AC KQAC "Q99" in 1993. It later picked up ABC's hot AC format as KNSY "Sunny 98.7." In the late 1990s, it became CHR KPRF "Power 98.7" and then "Kiss." In 2007, it changed to adult hits "Jack FM."
98.7 went on the air in the Fall of 1978 as KYTX "KY99" with an AOR format. Flipped to country KMML in January 1983 shortly after Mel Tillis bought it and KIXZ.
101.9 was AC KZZQ until it changed to easy listening KESE in 1988. After a couple months of that, it changed to country. In 1990, it flipped to rock KATP "Rock 102 the Cat." It went to country in the mid-1990s.
101.9 began in 1976 as KWAS, a religious station with preachers and CCM music. It flipped around 1986. Isn't KRGN in some way a lineal descendant of KWAS?
104.3 was rock KDXR until it went silent in 1988. It came back as country KQFX "the Fox" before the Spanish-language formats.
104.3 was pretty much a Borger local until a signal upgrade placed it in the Amarillo market. Can't remember if it was the sister to now-defunct KBBB 1600, or KQTY.
107.1 was rock KATP until 1988 when it became KHWK. KHWK ran then-Transtar's 24/7 satellite Niche 29 top 40/rock format as "the Hawk." It too went silent for a while. After that it became oldies KPUR-FM.
107.1 went on the air in January 1981 as KHBQ "Q-107". Fairly nicely done AC format, although the morning show (hosted by the owner and his wife) was awful.
