A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is main-
ly “line-of-sight.” That means you usually cannot hear stations
that are beyond the horizon.
GUIDE TO FREQUENCIES
National Weather Frequencies
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals cre-
ated inside the scanner’s receiver. These operating frequen-
cies might interfere with transmissions on the same
frequencies. If you program one of these frequencies, you hear
only noise on...

FREQUENCY CONVERSION
The tuning location of a station can be expressed in frequency
(kHz or MHz) or in wavelength (meters). The following informa-
tion can help you make the necessary conversions.
1 MHz (million) = 1,000 kHz (thousand)
• To convert MHz to kHz, multiply the...
