Page 36 FT DX 9000D OPERATION MANUAL

ANT

Connect your main antenna(s) here, using a type-M

(PL-259) plug and coaxial feedline for each. These

antenna ports are always used for transmission, and

also are used for reception unless a separate receive

antenna is also used for the main receiver. The inter-

nal antenna tuner affects only the antenna(s) connected

here, and only during transmission. These connectors

utilize TeflonR insulation for extreme durability and

to ensure stable impedance over the entire frequency

range.

RX OUT

These BNC jacks provide output of the receiver sig-

nal lines from the Antenna jacks which are connected

to the Main (VFO-A) and sub (VFO-B) front ends.

Main Power Switch

This is main power On (

)/Off (

) switch of the FT

DX 9000. Always turn this switch on before turning on

the front panel’s POWER button.

If this switch is not turned On, the front panel Power

switch will not function.

Turning this Main Power switch On supplies voltage

to the OCXO (Crystal Oven), ensuring that frequency

stability is always maintained even when the trans-

ceiver is turned off via the front panel's Power switch.

AC IN

Connect the supplied 3-wire AC line cord to this

socket. AC voltages of 100-240 V may be accommo-

dated by the FT DX 9000D without any sort of modifi-

cation (universal voltage input).

CIRCUIT BREAKER Switch

This circuit breaker shuts off in the event of danger-

ously high current consumption by the transceiver.

Advice

If the Circuit Breaker interrupts power, by all means

try to determine the cause of the over-current condi-

tion before re-applying power. To restore the Circuit

Breaker after verifying that all is normal, push this

switch in until you hear a “click.”

MIC

This 8-pin jack accepts input from a microphone uti-

lizing a traditional YAESU HF-transceiver pinout.

REMOTE

By plugging in the supplied FH-2 Remote Control Key-

pad to this gold-plated jack, direct access to the FT DX

9000D CPU is provided for control functions such as

contest memory keying, plus frequency and function con-

trol. This jack may also be also used for remote control

of the VL-1000 Linear Amplifier, if used.

RX ANT

This type-M jack is for a separate receive-only an-

tenna. An antenna connected here can be used, by both

the main (VFO-A) and sub (VFO-B) receivers, when

the RX ANT button on the front panel is pressed.

If you want to use some special kind of external

bandpass filter or preamplifier, you may connect it

between the RX OUT and RX ANT jacks, as shown

in the illustration.
