A GENERAL GUIDE TO SCANNING

Reception of the frequencies covered by your scanner is main-
ly "line-of-sight." That means you usually cannot hear stations
that are beyond the horizon.

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals cre-
ated inside the scanner's receiver. These operating frequen-
cies 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
birdie. This scanner's birdie frequencies (in MHz) are:
32.035 32.100
48.050 112.625
136.1375 144.150
160.165 166.200
392.4125 400.4125
429.050 432.450
464.4875 473.0375
496.5125 504.525
822.950 849.8625
897.9625 904.9375
930.0375 944.050
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 the scanner. Use the search function and search every
frequency range from its lowest frequency to the highest. Oc-
casionally, the searching will stop as if it had found a signal, of-
ten without any sound. That is a birdie. Make a list of all the
birdies in your scanner for future reference.
