KFYR (550 kHz) is an AM radio station located in Bismarck, North Dakota, owned by iHeartMedia, Inc. It transmits on a 5,000-watt signal that can be heard in seven U.S. states and three Canadian provinces. KFYR also broadcasts on translator K259AF (99.7 FM) in Bismarck. 99.7 FM was previously a simulcast of KQDY 94.5 FM before 2011. KFYR boasts an enormous coverage area. It can be heard across almost all of North Dakota during the day, as well as in parts of Minnesota, South Dakota, Montana, Manitoba, Saskatchewan and Nebraska. This owes to a combination of its position only one channel from the bottom of the North American AM dial, the height and power of its transmitter, and North Dakota's flat land. On the AM band, lower frequencies have longer waves, which tend to travel farther across terrain. This is especially true for stations that operate at 5,000 watts or more. Additionally, the flat landscape of the prairies makes for near-perfect ground conductivity, giving KFYR a coverage area comparable to that of a full-power FM station. 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. Even with this restriction, it still covers almost all of North Dakota at night. KFYR is the primary entry point station for the Emergency Alert System in both North and South Dakota. It has been claimed that KFYR has the largest land coverage area in the United States of any AM radio station during daytime hours. A similar claim can be made for WNAX in Yankton, South Dakota, which transmits on 570AM. (en) |
