KASE-FM (100.7 MHz "KASE 100.7") is a commercial radio station licensed to Austin, Texas. It is owned by iHeartMedia and airs a country music radio format. It shares studios and offices with four sister stations in the Penn Field complex in the South Congress district (or "SoCo") of south central Austin within walking distance of St. Edward's University. The transmitter site is off Waymaker Way in Austin, amid towers for other FM and TV stations.[2]

KASE-FM broadcasts in the HD Radio format.[3] It airs alternative rock on its HD2 subchannel, branded as "Alt 97.5," which is also carried on translator station K248CU on 97.5 MHz in Austin. KASE-FM and K248CU can also be heard on the iHeartRadio platform.


Weekday mornings, The Bobby Bones Show from Nashville is heard on KASE-FM.[4] It is syndicated by Premiere Networks, a subsidiary of iHeartMedia. On Saturday and Sunday mornings, KASE-FM features "The Best of Bobby Bones." Overnight, KASE-FM carries After MidNite with Granger Smith. The rest of the schedule is staffed by voice-tracked DJs from outside Austin.

In Austin, iHeartMedia owns two country stations. 98.1 KVET-FM plays of mix of current, recent and classic country, while KASE-FM concentrates on more contemporary country titles.


Beautiful music

KASE-FM first signed on the air on March 30, 1969, playing an automated beautiful music format.[5] It was co-owned with AM 1300 KVET, a popular AM country station. KASE-FM transmitted with an effective radiated power of 26,500 watts, a quarter of its current power.

After a little over a decade on the air, management saw an opening for a new FM format in Austin. While the AM station would continue to play an older, personality style of country and western music, KASE-FM was designed to appeal to younger country fans.

Switch to country

Bill Mayne, KASE Program director at the time, recalled in a 2010 interview, the Friday afternoon in September 1981 when KASE "came out of Mantovani and went into the Waylon Jennings song "Are You Ready for the Country" and had every dentist's office, nursing home and doctor's office in the city of Austin calling to complain."[6]

The "Continuous Country" format became a hit with Austin listeners and has consistently been voted by radio general managers as one of the top twenty "Most Admired Stations" in America. It was the first station to win the "Station of the Year" award from the Country Music Association four times and was given its second Billboard Magazine "Station of the Year" award in 1997.[7]

In 1990, KVET (AM) began simulcasting on 98.1 MHz. KASE continued to target adults in the 18-34 and 18-49 demographics, while KVET-FM targeted the 25-54 year old demographic.

Change in ownership

In 1998, KVET, Inc., which owned KVET-AM-FM and KASE-FM, sold its stations to Capstar, Inc.[8] Capstar was later merged into Clear Channel Communications, which is known today as iHeartMedia.

KVET and KASE have historically been Austin's top country stations, staving off many competitors over the decades. KASE-FM has also been nominated for the Country Music Association (CMA) "Large Market Station of the Year" Award numerous times.[9]

KASE 100.7

On March 11, 2024, after utilizing the brand "KASE 101" since its launch in 1981, KASE rebranded as "KASE 100.7", referencing its actual frequency.[10]
