Birdie Frequencies
Every scanner ha6 birdie frequencies. Birdies are signals created in¬
side the scanner’s receiver. These operating frequencies might inter- j
fere with broadcasts on the same frequencies. If you program one of ]
these frequencies, 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. You can also use the search skip memories to avoid
unwanted birdie frequencies.
Here are the birdie frequencies on this unit that you might want to
watch for:
38.4000 311.7500 313.1625 497.7500
74.2000 312.2875 322.1625 818.9750
115.2375 312.3000 341.8500 818.9875
132.2750 312.3125 345.7125 820.7000
137.6400 312.3250 368.7000 908.4500
137.6500 312.4625 380.8875 967.8000
230.4750 312.4750 4033375 1083.9500
288.0875 313.1250 428.6125 1083.9875
288.1000 313.1375 628.6250 1114.0500
311.7375 313.1500 455.3500 1260.3000
1290.4000
To find the birdies in any receiver, begin by disconnecting the antenna
and moving it away from the receiver. Make sure that no other nearby
radio or TV sets are turned on near the receiver. Use the search func¬
tion and scan every frequency range from its lowest frequency to the
highest. Occasionally, 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 necessary conversions.
1 MHz (million) = 1,000 kHz (thousand)
To convert MHz to kHz, multiply by 1,000.
9.62 MHz x 1000 = 9620 kHz
To convert from kHz lo MHz, divide by 1,000.
2780 kHz + 1000 = 2.780 MHz
To convert MHz to meters, divide 300 by the number of megahertz.
300 + 7.1 MHz = 42.25 meters
