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 horizon.
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 conditions. This type of
reception is unpredictable but often very interesting!
