EAR ANEL
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 internal 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.

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.

Main Power Switch
This is main power On (I)/Off (O) switch of the FT
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 9000D without any sort of modi-
DX
fication (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
9000 CPU is provided for control functions such as con-
test 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.
