Birdies typically occur with approximately equal strength with and without the scanner’s antenna attached. If you receive an interfering signal and suspect that it is a birdie, try removing the scanner’s antenna. If the interference disappears, the interference may be the result of other electronic equipment in the vicinity of the scanner. If the interference remains, it is likely a birdie signal.

It may be possible to adjust the squelch control and/or attenuator to minimize the effects of a birdie signal on scanning operation. Both of these methods will likely have some effect on the signal you are trying to monitor as well.

The scanner’s birdie frequencies (in MHz) are:
