History
On March 22, 1987, the station signed on as KAPT.[4] It was owned by Mark Grubbs, who also served as general manager. The station debuted with a hybrid top 40/country music format under the name "Capital FM," with the call sign spelling out "KAPiTal." (Austin is the capital of Texas.)
KAPT found little initial success against established Top 40 stations such as KHFI and KBTS (now KGSR). The station experimented with other formats including beautiful music, country music (during which it was branded as "The Country Kat" under KATG),[5]oldies (as "Froggy 94" under KFGI), and dance/CHR (as "Party 94.7" under KPTY).
In 1994, the Amaturo Radio Group bought the station for $2.5 million.[6] On October 24, 1994, "Froggy 94" switched to "Party 94.7", removing the only oldies station at the time in Austin. On September 1, 1995, Amaturo changed the station's format to modern adult contemporary as "Mix 94.7" with the call sign KAMX. In 1998, the station changed hands again, this time being acquired by Infinity Broadcasting.[7] Infinity was later merged into CBS Radio.
Over time,[when?] KAMX moved from Modern AC to Hot AC. In 2006, CBS announced it would sell 15 radio stations across the country to Entercom, including KAMX. The ownership change became official on November 30, 2007.[8] Coincidentally, CBS Radio merged into Entercom in 2017, with most of the former CBS Radio stations now owned by Entercom.
