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
National Weather Frequencies
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the scan-
ner’s receiver. These operating frequencies might interfere with transmissions 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 frequencies (in
MHz) are
:
To find the birdies in your individual scanner, begin by disconnecting the antenna
and moving it away from the scanner. Make sure that no other nearby radio or TV
sets are turned on near the scanner. Use the search function and search every fre-
quency range from its lowest frequency to the highest. Occasionally, the searching
will stop as if it had found a signal, often without any sound. That is a birdie. Make a
list of all the birdies in your scanner for future reference.
