Bridge Effect

Bridge Effect: by: Igor Grigorov, va3znw

Every day when I drive my car to and from my job I drive under bridges and arches.
Inside my car I usually listen to radio. My favorite radio is 680 News Radio. The radio station works on 680- kHz. This radio transmits useful news for me. It's the weather, what is and what will be news in Toronto and the World, as well as local traffic, which road is open, what the road is closed due to an accident construction. Knowledge of the traffic saves me a lot of time.

I noticed that volume of the 680-News usually is changed when I drove under a bridge or under an arch.
