KMER is an American AM radio station broadcasting on 940 kHz and is licensed to Kemmerer, Wyoming. It primarily broadcasts an oldies format, but occasionally broadcasts local high school football and basketball games from Kemmerer as well. KMER has national news at the top of the hour and weather during commercial breaks. KMER has a sister station KAOX on 107.3 MHzFM and KDWY 105.3 FM, which is licensed to Diamondville.
Prior to August 2006, KMER operated on 950 kHz with a higher power. In order to accommodate nearby KOVO AM 960's move from Provo, Utah to Bluffdale, Utah (which ultimately has not happened as of August 2010), KMER was forced to change its frequency from 950 to 940 and lower its power so as to not interfere with KOVO. Both stations are owned by Simmons Media.
KMER broadcasts from a tower located in Kemmerer, and with its 240 watt signal, covers much of southwestern Wyoming during the day. When conditions are favorable, KMER can be heard much farther distances, such as Salt Lake City, Utah.
