Birdie Frequencies

Birdie frequencies are signals that are internally generated by a radio scanner that can cause interference with some frequencies.

Birdies typically ocur with or without the scanner's antenna attached. If you suspect that a birdie may be interfearing with a particular frequency or channel, try removing the antenna to see if the interfearance disapears.

If the interfearance disapears, the interfearance is most likely the result of electronic equiptment in the vicinity of the scanner.

The following is a list of commonly known birdie frequencies. If you have a problem with a birdie frequency, simply lock it out.
