Ham Radio Frequencies
Ham radio operators often transmit emergency information when other means of communication break down.
The chart below shows the frequencies the scanner receives that ham radio operators normally use:
Wavelength Frequencies (MHz)
10-Meter 28.000-29.700
6-Meter 50.000-54.000
2-Meter 144.000-148.000
70-cm 420.000-450.000
33-cm 902.000-928.000
25-cm 1240.000-1300.000
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the scanner’s receiver. These
operating frequencies might interfere with transmissions on the same frequencies. If you program one of
these frequencies, you hear only noise on that frequency. If the interference is not severe, you might be able
to turn SQUELCH clockwise to cut out the birdie.
This scanner’s birdie frequencies (in MHz) are:

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. This is a birdie. Make a list of all the birdies in your scanner
for future reference.
