Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals creat-

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.
