Birdie Frequencies

All scanners have signals created inside the scanner’s receiver. These birdie frequencies can interfere with transmissions on the same frequencies. If the interference is not severe, you might be able to turn SQ clockwise to omit the birdie.

To find the birdies:

1.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.

2.Start a search of every frequency range from its lowest frequency to the highest. When the search stops, often without any sound, this is a birdie.

3.Make a list of all the birdies in your scanner for future reference.
