This is due to its location near the bottom of the AM dial; lower frequencies have longer waves that tend to travel farther across terrain.

It has been claimed that KFYR has the largest daytime coverage area of any AM radio station in the United States.

At night, two towers are used in a directional pattern to protect CBK, the CBC Radio One outlet for most of Saskatchewan, which operates on nearby 540 AM.

In its early years, it was an affiliate of the NBC Red Network, airing its dramas, comedies, news and sports during the "Golden Age of Radio."

Many popular soap operas, game shows, sporting events, religious services, children's programs, and big band broadcasts were part of the regular schedule.

Mike Dosch, an established musician from Strasburg, North Dakota (Lawrence Welk's hometown) was featured on several of the live shows and had his own late-night program of organ music for many years.

There were also shows hosted by staff announcers who played recorded popular music by such artists as Nat King Cole, Doris Day, The Ames Brothers, Fred Waring and the Pennsylvanians, and orchestras including Mantovani, Percy Faith, and Frank Chacksfield.

Facing stiff competition from more youthful stations, KFYR began to see its dominance and audience decline in the early 1960s.

In the 1960s and 1970s, teenagers from South Dakota to parts of Canada enjoyed listening to "their" music on KFYR every evening (along with 1520 KOMA from Oklahoma City, 1090 KAAY from Little Rock, 890 WLS from Chicago, and 1500 KSTP from St. Paul).

KFYR gained brief national notoriety in 1979, when the station was sued in federal court by the Pointer Sisters and Elektra Records.

The rest of the weekday schedule is made up of nationally syndicated conservative talk programs: The Clay Travis and Buck Sexton Show, The Jesse Kelly Show, Our American Stories with Lee Habeeb, Coast to Coast AM with George Noory and America in the Morning.
