These maps are drawn using engineering data from the FCC. The coverage pattern for each FM station is calculated using the effective radiated power (ERP) of the station and the antenna height above average terrain (HAAT).

Click on a frequency or channel to generate a map of the AM, FM, or TV licensed stations in the USA that are using the specific frequency or channel. AM options include daytime groundwave coverage and nighttime primary and secondary skywave coverage.

Oct 13, 2023 · Using the FCC's F (50,50) propagation curves, distances to the FM service contours are generated from the effective radiated power in a given direction, and the radial antenna height above the average elevation of that same radial.

Dec 11, 2015 · The following table lists the various classes of FM stations, the reference facilities for each station class, and the protected and city grade contours for each station class.

The daytime maps show expected ground-wave coverage patterns at two levels, out to the 1.0mV/m and 0.1mV/m field strength contours (60 dBu and 40 dBu respectively). These levels were chosen to closely match those which might be helpful to the MW DXer.

These coverage maps use information provided in Ofcom Databases regarding site location, elevation, antenna height, frequency, power and antenna pattern/orientation. Scroll down the list, or use the yellow filter boxes.
