We have had a lot of ducting lately. Tropospheric ducting causes interference with over the air TV signals. Tropospheric ducting occurs when a TV or radio signal is reflected off of the troposphere and continues on a path that allows the signal to travel much farther than it normally would. This occurs when the temperature in the atmosphere experiences a shift called an inversion. When a temperature inversion occurs, radio waves that would normally continue into space beyond the Earth’s atmosphere are instead reflected and continue to follow the curvature of the planet. Florida often receives interference on channel 9 from WEAR TV in Pensacola. I have seen this a lot in early morning and evening as of late.
