PATCH
This gold-plated RCA input jack accepts transmitter
audio - either AFSK or voice - for transmission. This
line is mixed with the microphone audio input line, so
the microphone should be disconnected if using this
jack and mixing is not desired. The optimum imped-
ance is 500 ~ 600 Ohms, and the nominal input level
should be 1 mV.
EXT SPKR
The EXT SPKR two-contact output jacks are gold
plated, providing audio from the Main (VFO-A) and
Sub (VFO-B) receivers for an FPS-9000H's speak-
ers. Inserting a plug into one of these jacks disables
the corresponding internal loudspeaker. Impedance is
4 ~ 8 Ohms.
AF OUT
This gold-plated 3-contact jack provides dual-chan-
nel low-level receiver output, for recording or exter-
nal amplification. Peak signal level is 3 Vrms at 10 k-
Ohms. Main band (VFO-A) receiver audio is on the
left channel (tip), and Sub band (VFO-B) receiver au-
dio is on the right channel (ring). A stereo amplifier or
recorder is recommended, to record each receiver's
audio separately when dual reception is enabled (au-
dio from either receiver, or both, may be used via this
jack). The front panel [ AF GAIN ] knobs do not affect
the signals at this jack.
RTTY
This 4-pin input/output jack provides connections for
an RTTY terminal unit. Pinout is shown on page 139.
The receiver audio level at this jack is at a constant
100 mV level (@600 Ohms). FSK keying at this jack
is accomplished by a closure of the SHIFT line to
ground by the terminal unit.
PACKET
This 5-pin input/output jack provides receiver audio
and squelch signals, and accepts transmit (AFSK) au-
dio and PTT control, from an external Packet TNC.
Pinout is shown on page 138. The receiver audio level
at this jack is approximately 100 mV (@600 Ohms).
TRV
This gold-plated RCA jack provides a low level RF
output for use with a transverter. Maximum output is
approximately –20 dBm (0.01 mW) at 50 Ohms.
ACC
This is an accessory jack which is used at the factory
for adjustment of the radio. Please do not connect any
cable or accessory to this terminal.

ANUAL
TXGND
This jack's center pin is closed to ground while the
transceiver's transmitter is engaged. It may be used
for control of a peripheral device, most typically a
linear amplifier. To enable this jack, please set Menu
item "TX GNRL 172 EXT AMP TX-GND" to the
"ENABLE" selection. This RCA connector is gold-
plated, and the specifications are shown below.
BAND DATA
BAND DATA1
This 8-pin output jack provides band selection data
which may be used for control of optional accessories
such as the VL-1000 Solid-state Linear Amplifier.
BAND DATA2
This 7-pin output jack used for control of the VL-1000
Solid-state Linear Amplifier.
EXT ALC
This gold-plated RCA input jack accepts negative-go-
ing external ALC (Automatic Level Control) voltage
from a linear amplifier, to prevent over-excitation by
the transceiver. Acceptable input voltage range is 0 to
–4 VDC.
ROTATOR
This 6-pin MINI-DIN Jack accepts a cable connected
to a YAESU G-800DXA/-1000DXA/-2800DXA An-
tenna Rotator. You may control the antenna azimuth
rotation (and rotation speed) using the Function but-
tons on the front panel. (Listed models are current as
of 2008).
KEY
This 1/4-inch gold-plated phone jack accepts a CW
key or keyer paddle. A 2-contact plug cannot be used
in this jack. Key-up voltage is +5 V, and key-down
current is 1 mA. Plug wiring is shown on page 16, and
this jack may be configured for keyer, "Bug," "straight
key," or "computer keying interface operation" via
MODE-CW 050 R-KEYER TYPE
Menu item "
(see page 151).
CAT
This 9-pin serial DB-9 jack allows external computer
control of the FT 9000MP. Connect a serial cable
DX
here and to the RS-232C COM port on your personal
computer (no external interface is required).
GND
Use this terminal to connect the transceiver to a good
earth ground, for safety and optimum performance.
Use a large diameter, short braided cable for making
ground connections, and please refer to page 14 for
other notes about proper grounding.
