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 cut out the birdie. -
Page 32: Band Allocation
Aircraft and Others Aircraft Note: Your scanner rounds the entered frequency to the nearest valid frequency. For example, if you try to enter 151.473, the scanner ac- cepts this as 151.475.
