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:
National Weather Frequencies
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
SQUELCH clockwise to cut out the birdie. This scanner’s
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
