employ this wire and resistor but it may be necessary to check
them for correct operation.) Another method of suppression
is the use of additional noise suppressors. These can be

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 be
received at great distance. This is because broadcasting
signals follow the curvature of the earth and are reflected
back by the upper atmosphere.
