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.

Ham Radio Frequencies
Ham radio operators often transmit emergency information when other means of
communication break down. The following chart shows the frequencies the scanner
receives that Ham radio operators normally use.
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the scan-
ner’s receiver. These operating frequencies might interfere with broadcasts on the
same frequencies. If you program one of these frequencies, you hear only noise on
that frequency. If the interference is not severe, you might be able to turn

coun-
terclockwise to cut out the birdie.
