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.

GUIDE TO FREQUENCIES

Ham Radio Frequencies

Ham radio operators often broadcast emergency information
when other means of communication break down.
The following chart shows the voice frequencies that you can
monitor:
Wavelength (Meters)
10-Meter
6-Meter
2-Meter
70-Centimeter

National Weather Frequencies

162.400 162.425
162.500 162.525

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals creat-
ed inside the scanner'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 clockwise to cut out the birdie. This scanner's
SQUELCH
birdie frequency (in MHz) is 146.65 MHz.
To find the birdies in your individual scanner, begin by discon-
necting the antenna and moving it away from the scanner. Make
sure that no other nearby radio or TV sets are turned on near
