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!
