Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside
the scanner’s receiver. These operating frequencies might interfere with
broadcasts on the same frequencies. If you program one of these fre-
quencies, 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.
The birdie frequencies on this unit to watch for are:
To find the birdies in your 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 scan every frequency range from its lowest frequency to the high-
est. 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.
