PRO-2002 AM/FM Scanning Receiver
(200-0116) Birdies Faxback Doc. # 18976
Some frequencies may be difficult or impossible to receive. If you
program-in one of these, the Scanner may lock up and you hear only noise.
These "birdies" are the products of internally generated signals mixing
with external signals like TV and FM broadcasts. Telescopic antennas are
much more likely to pick up these undesirable signals-that is another good
reason for getting an outdoor, base-station type antenna for home
installations.
If the interference is not severe, you may be able to use SQUELCH to cut
out such annoying birdies.
A few of the most common birdies to watch out for are listed below.
30.730 MHz 42.735 MHz
30.735 ~
30.745 42.860
32.000 44.790
32.005 ~
38.395 44.810
38.400 115.200
38.405 121.600
40.975 128.000
~
40.990
Even with the SQUELCH control set to maximum, scanning or searching may
stop on or around some of the frequencies listed above. If the spurious
signal is strong enough (above 10uV in technical terms) you can listen to
it, but the Receiver will not auto scan/search.
