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

162.400

162.425

162.450

162.475

162.500

162.525

162.550

Canadian Weather Frequencies

161.650 161.775 163.275

Note: These frequencies are not pre-programmed in the weather service bank but can be manually programmed into a channel.

Ham Radio Frequencies

Ham radio operators often transmit emergency information when other means of communication break down. The following chart shows the frequencies the scan- ner receives that Ham radio operators normally use:

Wavelength (meters)

Frequencies (MHz)

10–Meter

29.000–29.700

6–Meter

50.000–54.000

2–Meter

144.000–148.000

70–cm

420.000–450.000

33–cm

902.000–928.000

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals created inside the scanner’s receiver. These operating frequencies might interfere with broadcasts 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.
