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.

US Weather Frequencies
Ham Radio Frequencies
Ham radio operators often transmit emergency informa-
tion when other means of communication break down.
The chart below shows the frequencies the scanner re-
ceives that ham radio operators normally use:
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals
created inside the scanner’s receiver. These operating
frequencies might interfere with transmissions on the
same frequencies. If you program one of these frequen-
cies, you hear only noise on that frequency. If the interfer-
ence is not severe, you might be able to turn
SQUELCH
clockwise to cut out the birdie.
