Birdie Frequencies
Every scanner has birdie frequencies. Birdies are sig- nals created inside the scanner’s receiver. These operat- ing frequencies might interfere with broadcasts on the same frequencies. If you program one of these frequen- cies, you hear only noise on that frequency. If the interfer- ence is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie.
The birdie frequencies on this unit to watch for are:
30.735 | 37.800 | 38.400 |
40.000 | 40.980 | 41.900 |
51.200 | 140.800 | 149.400 |
158.085 | ||
163.920 | 166.400 | 384.000 |
396.800 | 409.600 | 422.400 |
435.200 | 448.000 | 460.800 |
473.600 | 486.400 | 499.200 |

To find the birdies in your scanner, begin by disconnecting 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. Use the search function and scan every frequency range from its lowest frequency to the highest. 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.
