note
The TX GND OUT pin (pin 2) of the LINEAR jack
is a transistor “open collector” circuit. It is capable of
handling positive relay coil voltages up to +60VDC
at 200 mA or +30 VDC at 1 A. If you plan to use
multiple linear amplifiers for different bands, you
must provide external band switching of the “Linear
Tx” relay control line from the “TX GND OUT” line
at the LINEAR jack.
The specied range for ALC voltage to be used with
the FT DX 3000 is 0 to -4 Volts DC.
Amplier systems utilizing different ALC voltages
will not work correctly with the FT DX 3000, and
their ALC lines must not be connected if this is the
case.
iMportAnt note!
Do not exceed the maximum voltage or current rat-
ings for the “TX GND OUT” pin (pin 2) of the LIN-
EAR jack. This line is not compatible with negative
DC voltages, or AC voltages of any magnitude.
Most amplifier control relay systems require only
low DC voltage/current switching capability (typi-
cally, +12V DC at 25 ~ 75 mA), and the switching
transistor in the FTDX3000 will easily accommodate
such ampliers.

Color Code Information
Note
When the FC-40 is connected to the FTDX3000,
TX GND (pin 2) of the TUNER jack and the
LINEAR jack (pin 2) are common circuits.
Therefore, the maximum voltage at TX GND (pin
2) of the LINEAR jack must not exceed +5V.

If the knob is turned too slowly, the frequency
display may not show the value. This is to pre-
vent undesired display of the functions caused
by noise or slight vibration of the controls;
however, the actual value will be changed even
if not displayed.
You can observe the ne adjustment for a few
seconds while the display is active.
While adjusting functions, the display may oc-
casionally skip one of the numbers in the se-
quence; this is due to “rounding” of the encoder
steps in the ADC converter. Set the values to
your preference, they are unique to your radio
and may not directly correspond to other units.
