To automatically search the entire COMM frequency range for a broadcasting signal, the
Up Key or Down Key may be pressed and held for one second. The Screen will display
SEARCH as seen below.
The frequencies will either scroll up or down in 25 KHz steps depending upon whether
the Up or Down Key was used to initiate the Search.
When a broadcasting signal is found, the word SEARCH will flash and the JD-200 will
stop temporarily on that frequency. If the broadcasting signal is cut off for more than two
seconds, the Search will resume until another signal is found. When 142.975 MHz is
reached during an upward Search, the Search automatically continues at 118.000 MHz.
Likewise, when 118.000 MHz is reached during a downward Search, the Search
automatically continues at 142.975 MHz.
The Search may be canceled at any time by pressing the Clear Key. The direction of the
Search may also be reversed at any time by pressing and holding the Up or Down Key
(whichever is appropriate) for one second.
It is very important that the Squelch be properly adjusted prior to initiating a Search. The
background static received with the squelch off may be strong enough to disrupt a
Search. If a Search gets “stuck” on a frequency with too much background noise,
increase the Squelch or press and hold the Up or Down Key for one second to skip that
frequency and resume Searching.
Frequency Memory
The JD-200 has 20 memory channels numbered 00 to 19 to store those frequencies used
most often. These memory channels may be used to store COMM and NAV frequencies.
Select a desired frequency, such as 122.70, to be stored by using either manual frequency
selection or frequency search. To store this frequency, press the Memory Key. The
following screen will appear.
The first available memory channel will be displayed on the top line of the screen. In this
example, memory channel 01 is the first available location, so we know a frequency is
already stored in memory channel 00. To store the frequency, press the Memory Key a
second time. The screen will now display the following for one second to verify 122.70
has been stored in memory channel 01.
