From : radioworld.com on 2024-11-29In his time in radio and television, Dan Slentz more than once has had to explain the effects of atmospheric ducting. It seems the more stations that are squeezed in, the higher the likelihood of a stray signal on or near your frequency being "ducted" down on you from far away. William Hepburn runs the DX Info Centre Tropospheric Ducting Forecast site. It provides a six-day forecast of potential VHF, UHF and microwave radio and TV anomalous propagation. Colored interference zones are displayed on a map of the United States. The forecast predicts areas where the necessary atmospheric conditions are present where tropospheric bending of TV and radio waves could occur, extending the range of radio and television signals far beyond their normal limits.
