WKAN 1320 AM

A regional AM broadcast frequency allocated for use by multiple stations across different geographic regions through careful coordination of transmitter locations, power levels, and operating schedules to minimize interference between co-channel facilities. The Federal Communications Commission and Canadian Radio-television and Telecommunications Commission classify this frequency as regional, distinguishing it from clear channels reserved for powerful stations serving large areas and local channels shared by numerous low-power stations serving individual communities. Regional frequency allocations represent a compromise in AM spectrum management, allowing more stations than clear channel assignments while providing better coverage than purely local facilities. Stations sharing regional frequencies must operate with power levels and antenna patterns engineered to protect other users of the same channel, particularly at night when AM signals propagate over much greater distances due to ionospheric reflection. This often requires stations to reduce power after sunset or switch to directional antenna patterns that focus signals toward intended coverage areas while minimizing radiation toward other stations on the frequency. The engineering complexity of managing hundreds of stations across regional frequencies requires sophisticated coordination and technical standards developed over decades of broadcast regulation. Multiple countries use this frequency for domestic broadcasting, each managing assignments within their borders according to national regulatory frameworks while participating in international coordination agreements to prevent cross-border interference. In the Americas, coordination between the United States, Canada, and Mexico follows bilateral agreements that allocate frequencies and establish technical standards for border regions where signals from multiple countries might interfere. The specific stations operating on this frequency vary by region and change over time as licenses are granted, renewed, modified, or deleted through normal regulatory processes. AM broadcasting continues to evolve with some stations adding FM translators to improve coverage and audio quality, while others transition to different formats or cease operation as audience preferences shift toward FM and digital audio platforms.
