KCVM (93.5 FM) is a commercial radio station located in Hudson, Iowa serving the Waterloo/Cedar Falls, Iowa area. The station broadcasts an adult hits music format. KCVM is licensed to James Coloff's Coloff Media, LLC.

The transmitter and broadcast tower are located northeast of Hudson. According to the Antenna Structure Registration database, the tower is 109 m (358 ft) tall with the FM broadcast antenna mounted at the 104 m (341 ft) level.[1] The calculated height above average terrain is 99 m (325 ft).


KCVM was originally broadcast on 96.1 MHz from its inception in the 1990s until July 2010. However, due to the need to protect several other stations in nearby markets from interference, the station had broadcast at an effective radiated power of 6 kilowatts with an extremely directional antenna pattern to avoid co-channel interference to stations such as KNWM in Madrid (Des Moines), KQPR in Albert Lea, Minnesota, and KMXG in Clinton (Quad Cities). KCVM was also required to protect KCHA-FM (95.9 MHz) in Charles City from adjacent-channel interference.

On June 4, 2010, it was announced that KCVM would be moving from 96.1 to 93.5[2] and by July 22, KCVM had made the switch to 93.5 MHz; a frequency which allows the station to better serve the Cedar Valley since there are fewer stations on and near the 93.5 frequency that require protection from interference.[3]

KCVM still broadcasts at an effective radiated power of 6 kilowatts at a height of 99 meters and is still a Class A FM radio station on 93.5, just as it was on 96.1, but the directional antenna pattern is not as severe now as it was when KCVM was broadcast on 96.1 MHz.

Signal upgrade application[edit]

KCVM currently has an application on file with the FCC to upgrade its signal again. This time, the plan is to change the city of license from Hudson to Evansdale, and to upgrade from a Class A license to a Class C3 license, with a boost in power from its current 6 kilowatts up to 24.5 kilowatts, at an antenna height of 81.8 meters. Also, the proposed antenna pattern is non-directional.[4] The new transmitter would be located east of Waterloo and north of Evansdale, on East Big Rock Road between Crane Creek Road and North Raymond Road (County Highway V49) in Black Hawk County.[5] The proposed upgrade would add outlying Cedar Valley communities such as Waverly, Oelwein, and Independence to KCVM's 60 dBu protected/city grade coverage coutour for the first time ever, as those communities have always received anywhere from marginal to poor reception from KCVM, especially on the previous 96.1 frequency (Oelwein and Independence would often receive KMXG in addition to KCVM back when KCVM was on 96.1; especially during times of tropospheric propagation).
