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

National Weather Frequencies

162.400	162.475	162.525
162.425	162.500	162.550
162.450

Canadian Weather Frequencies

161.650161.775163.275

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

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are sig- nals created inside the scanner’s receiver. These oper- ating 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 inter- ference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie.

This scanner’s birdie frequencies (in MHz) are:

31.2000	41.6000	52.0000	138.7100
138.7150	145.6000	148.6200	165.3000
171.2500	406.2250	407.7625	407.8125
413.1750	413.2250	416.1375	426.0375
426.0500	435.9500	455.7625	455.8625
455.7750	465.6750	475.5875	485.4875
489.2500	495.4000	505.3000	505.3125
