KFBC

KFBC (1240 AM) is an American sports formatted radio station based in Cheyenne, Wyoming and targets the entire market. The station is a full time affiliate of CBS Sports Radio as well as the Flagship station of the Cowboy State News Network. Additionally, KFBC is a part-time affiliate of the Denver Broncos and Colorado Rockies (both through KOA) as well as the Wyoming Cowboys. In KFBC's early days, they were part of the NBC Blue Network, which is now ABC News Radio. It is unclear whether KFBC is still part of ABC or not.
Signal.
KFBC puts out a continuous 700 watts of non-directional power which provides local coverage to Cheyenne and the surrounding area, while it can be marginally heard in Western Nebraska, Northern Colorado (even Fort Collins), and some of South-east Wyoming. KFBC is unusual in the fact that Class C stations are normally 1,000 watts, such as KRAL. The station is on one of six shared-local frequencies (the others are 1230, 1340, 1400, 1450, and 1490), informally referred to as the "graveyard" frequencies, because of the excessive number of stations. Because of this, the skywave (night-time) signal mixes with several others, thus limiting its usefulness to its groundwave signal. However, a skilled operator with a very directional antenna may separate it from the rest, upwards of 300 miles.
To provide another option, as well as to take advantage of AM Revitalization, KFBC signed on translator K248CZ, (97.5 FM) located Downtown at 250 watts, just a few miles away from the KFBC tower. This signal provides a local grade signal to the city itself, and depending on the conditions, can extend to the Nebraska Panhandle, much like its parent station. This is more likely to happen at night or when there is more humidity in the air. In general, the translator copies everything from the KFBC broadcast; it even broadcasts in mono, a rarity for modern-day FM translators, although still the standard for some AM stations.
History.
According to the KFBC website, they have been active for 75 years as of 2021, which would put their start date as 1946, however records indicate they were around since at least 1941, albeit on the frequency of 1450. Meanwhile, KYAN was on 1400, who eventually sold their facilities to KFBC the same year. (This is however disputed by this source which is dated 1942). The likely founder and owner of the station was media mogul Tracy McCracken.
KFBC originally was an independent station before becoming an affiliate of NBC Blue, before going independent again. From the very start, KFBC was very sports orientated, being the first to hire Curt Gowdy as a broadcaster. The McCracken family started KFBC-TV (now KGWN-TV) in 1954, effectively making the two sister outlets, along with the Wyoming Tribune Eagle. 
In the 21st century, KFBC was taking on a more news/talk role omnipresent of post-golden era stations, while including some sports, like the Motor Racing Network. A massive shake-up of Cheyenne AM affiliations occurred between 2006 and 2016; fellow station KRAE went from classic country to ESPN to oldies. Upon KRAE's switch from sports to oldies, KFBC took up the position as Cheyenne's sports station, which the station management regarded well. Meanwhile, KGAB picked up KFBC's news and talk status. Both KFBC and former sister station '92.9 The Boss' launched "Christmas Cash" in the 2010s, a give-away contest that continues to exist as of the 2020 Holiday season. In the 2020's, KFBC continues to serve as Cheyenne's CBS Sports Affiliate and will occasionally air local games and events. Recently, the station will play music during fireworks, mainly for 4th of July, and now for New Year's Day fireworks. 
Programming.
The vast majority of the schedule is syndicated from CBS Sports Radio, however local programming preempts the national feed occasionally, and KFBC produces two shows each weekday. During the weekend, no local programming (besides live coverage of sports) is produced. One of the producers of the Jim Rome Show, Adam Hawk, achieved infamy when a parody of 's theme song included his name.
