Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside

To find the birdies in your receiver, begin by disconnecting the antenna
and moving it away from the receiver. Make sure that no other nearby

est. 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.
