KOA is a Class A, clear-channel station, broadcasting at 50,000 watts non-directional, the maximum power permitted by the Federal Communications Commission for AM stations. By day, the station provides city-grade coverage to most of Colorado's densely populated area, including cities such as Colorado Springs, Pueblo and Fort Collins. It provides at least secondary coverage to most of eastern Colorado, along with portions of Wyoming. Under the right conditions, it reaches portions of Nebraska and Kansas. With a good radio at night, the signal can be heard over much of the Central and Western United States, and parts of Canada and Mexico. KOA is nicknamed "the Blowtorch of the West".[2] It is Colorado's primary entry point station for the Emergency Alert System.
As of November 1, 2015, KOA is also heard on 94.1 MHzK231BQ, which is licensed to Golden, Colorado, as an FMtranslator of KBCO-HD3. In addition, KOA also simulcasts on translator K231AA (also on 94.1 MHz), licensed to Boulder.[2][3]
History
KOA was first owned by General Electric and began broadcasting on December 15, 1924.[4] The station started with 5,000 watts, and in 1927, increased to 12,500 watts. KOA became an NBC affiliate in 1929, and the network took over operation of the station from GE shortly thereafter. On July 7, 1934, power was raised to the current level of 50,000 watts.[5] In 1941, NBC, which had been operating KOA and KGO in San Francisco for GE since October 1, 1929, also took over ownership of the stations. NBC continued to own KOA until June 1953 when it sold the station to Metropolitan Television Company, whose principal stockholder was Bob Hope. That same year on Christmas Eve, KOA started a sister TV station, KOA-TV on channel 4; like its radio cousin, it was affiliated with the NBC Television Network. KOA-FM was added in June 1961, which in 1974 became Top 40 KOAQ (Q103). GE repurchased the stations in 1968 and continued to own them until 1983 (keeping the aforementioned channel 4, which was subsequently rechristened as KCNC-TV), when it sold KOA and KOAQ to Belo Corporation. In 1987 Jacor Communications purchased KOA and KOAQ; Jacor was purchased by Clear Channel Communications in 1999. The company rebranded to iHeartMedia in 2014.
Former Rocky Mountain News columnist Mike Rosen, who retired at the end of 2015, was the long-running host of the 1 to 3 p.m. show. Rosen is a fiscal conservative and social libertarian who occasionally was a substitute host for Rush Limbaugh. Common Rosen-isms are "tell me where you sit before you tell me where you stand" and "a politician asks what you want, an economist asks what you want more". Rosen's philosophy is reflected in his recommended reading list which includes Ayn Rand, Adam Smith, Paul Johnson and Thomas Sowell.
Other well-known local voices previously heard on KOA include Bob Martin, Don Zimmer, Gus Mircos, and Alex Stone. Rollye James and George Weber. The late Rick Barber was heard for 30 years on KOA. Consumer advocate Tom Martino and former FEMA official Michael D. Brown were KOA hosts until they switched to sister stationKHOW.
Also in the 1980s, during the weekend evening hours on KOA, Larry Cox, and his dog Wilbur, would host the radio program The National Recovery Act, a listener-friendly call-in show. A certain topic was announced and people from all over the nation, picking up the KOA signal at night, would call in with their memories. Big band music from the 1930s and 1940s was also played. The program would always end with the song "And So To Bed". In December 1987, Cox began a new radio program, No Place Like Home, broadcast from his home on Chicago Creek. Listeners would often hear the fireplace crackling and Cox's dog, Wilbur, snoring.[citation needed]
With the launch of conservative talk sister station KDFD "Freedom 93.7" in 2019, The Rush Limbaugh Show moved exclusively from KOA to KDFD in September 2019, and the station launched the new afternoon drive show Big Al & JoJo (co-hosted by former Denver Broncos player and KKFN host Alfred Williams), resulting in its existing sports show Logan & Lewis moving to late-mornings.[6][7]
In June 2022, longtime co-anchor of Colorado's Morning News April Zesbaugh retired.[8][9][10]
