WWKB's daytime signal decently covers all of Western New York, including Rochester, as well as the Southern Tier. It also provides secondary coverage to much of Southern Ontario, including Toronto, and can be heard as far east as Kingston. At night, it must direct its signal eastward due to sharing a frequency with KOKC in Oklahoma City, Oklahoma (the former KOMA, another flame-throwing 50,000-watt Top 40 powerhouse in the 1960s and 1970s). Thus, while the station can be heard across most of the eastern half of North America at night, its signal is spotty at best only 20 miles southwest of Buffalo. Its directional quality is due to the configuration of its transmitter tower array, which has resulted the station being commonly heard very well in parts of Sweden at night during the winter months. A group of Scandinavian radio reception enthusiasts actually traveled to the United States to have a conference at a Camp Road motel, with the purpose of viewing the array for themselves, apparently to photograph and measure it. Residents of the neighborhood remain largely unaware that the antenna array is internationally famous for sending the 1520 signal all the way to the outskirts of Stockholm on a regular basis.
