PRO-90 300-Channel Trunk Tracker Scanner
(200-0520A) Scanning Guide Faxback Doc. # 60725
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:
161.650 161.775 163.275
Note: These frequencies are not pre-programmed in the weather service
bank but can be manually programmed into a channel.
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.
This scanner's birdie frequencies (in MHz) are:
41.6000 406.2000 438.4000 489.2500
118.8875 413.1750 445.8250 495.3625
138.7000 413.2250 445.8375 496.3750
138.7050 416.1125 455.7375 813.4000
158.5150 426.0125 465.6500 852.0375
158.5200 426.0250 475.5500 899.2375
168.4250 435.9250 485.4625 926.7000

Frequency Conversion
The tuning location of a station can be expressed in frequency (kHz or
MHz) or in wavelength (meters). The following information can help you
make the necessary conversions.
1 MHz (million) = 1,000 kHz (thousand)
To convert MHz to kHz, multiply the number of megahertz by 1,000:
9.62 (MHz) x 1000 = 9620 kHz
To convert from kHz to MHz, divide the number of kilohertz by 1,000:
2780 (kHz) divided by 1000 = 2.780 MHz
To convert MHz to meters, divide 300 by the number of megahertz:
300 divided by 7.1 MHz = 42.25 meters
