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.

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals creat-
ed inside the scanner'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

ner's birdie frequencies (in MHz) are:
30.075
48.025
136.725
166.400
416.0375
456.075
480.575
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 frequen-
cy 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.
