GENERAL GUIDE TO SCANNING
BIRDIE FREQUNCIES
Every scanner has birdie frequencies. Birdies are signals
created inside the scanner's receiver. These operating fre-
quencies might interfere with broadcasts on the same fre-
quencies. If you program one of these frequencies, you hear
only noise on that frequency. If the interference is not se-
vere, you might be able to turn SQUELCH clockwise to cut
out the birdie.
The birdie frequencies on this unit to watch for are:
29.800
52.250
85.400
153.190
161.580
To find the birdies in your scanner, being 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 highest. Occasionally,
the searching will stop as if it had found a signal, often with-
out any sound. That is a birdie. Make a list of all the birdies in
your scanner for future reference.
