A General Guide to Scanning

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals created inside the

scanner’s receiver. These operating frequencies might interfere with transmis-

sions 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.

To find the birdies in your individual scanner, begin by disconnecting the an-

tenna and moving it away from the scanner. Make sure that no other nearby

radio or TV sets are turned on near the scanner. Use the search function and

search every frequency range from its lowest frequency to the highest. Occa-

sionally, the searching will stop as if it had found a signal, often without any

sound. That is a birdie. Make a list of all the birdies in your scanner for future

reference.

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 nec-

essary conversions.

1 MHz (million) = 1,000 kHz (thousand)

• To convert MHz to kHz, multiply the number of megahertz by 1,000:

30.62 (MHz) x 1000 = 30,620 kHz

• To convert from kHz to MHz, divide the number of kilohertz by 1,000:

127,800 (kHz) / 1000 = 127.8 MHz

• To convert MHz to meters, divide 300 by the number of megahertz:

300 / 50 MHz = 6 meters

CARE

Keep the scanner dry; if it gets wet, wipe it dry immediately. Use and store the

scanner only in normal temperature environments. Handle the scanner care-

fully; do not drop it. Keep the scanner away from dust and dirt, and wipe it with

a damp cloth occasionally to keep it looking new.
