Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals created in- side the scanner’s receiver. These operating frequencies might inter- fere with broadcasts on the same frequencies. If you program one of these frequencies, you hear only noise on that frequency. If the inter- ference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie.

The birdie frequency on this unit to watch for is 146.65 MHz.

To find the birdies on your receiver, begin by disconnecting the anten- na and moving it away from the receiver. Make sure that no other near- by radio or TV sets are turned on near the receiver. 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 without any sound. That is a birdie. Make a list of all the birdies in your scanner for future reference.
