A General Guide to Scanning
Reception of the frequencies covered by your scanner is mainly “line-of-sight.” That means you usually
cannot hear stations that are beyond the horizon.
GUIDE TO FREQUENCIES
US Weather Frequencies in MHz
162.400 162.425 162.450 162.475
162.500 162.525 162.550
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
