A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered
by your scanner is mainly “line-of-
sight.” That means you usually cannot
hear stations that are beyond the hori-
zon.
During the summer months, you might
be able to hear stations in the 30–50
MHz range located several hundred or
even thousands of miles away. This is
because of summer atmospheric con-
ditions. This type of reception is unpre-
dictable but often very interesting!
