Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created 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 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 frequency 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.
