Birdie Frequencies

Every scanner has birdie frequencies. Birdies
are signals created inside the scanner's receiver,
which may 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 omit the birdie.
To find the birdies in your scanner, disconnect 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 Tune
function and scan 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. This is a birdie. Make
a list of all the birdies in your scanner for future
reference.
