Interference
Radio reception in a moving environment is very different from reception in a
stationary environment (home). It is very important to understand the difference.
AM reception will deteriorate when passing under a bridge or when passing
under high voltage lines. Although AM is subject to environmental noise, it has
the ability to receive at great distance. This is because broadcasting signals
follow the curvature of the earth and are reflected back by the upper atmosphere.
