ONNECTIONS
IF OUT Jacks
This RCA jack outputs the 9 MHz IF signal of the re-
ceived signal when Menu item “
109 RGEN IF OUT
”
is set to “ ENABLED ”. This signal does not pass through
the roofing filter.
ANT 1, 2, 3, 4 Jacks
Connect your main antenna(s) here, using a type-M
(PL-259) plug and coaxial feedline for each. These an-
tenna ports are always used for transmission. They are
also used for reception, unless a separate receive an-
tenna is connected to the
RX ANT IN jack and used
for the receiver. The internal antenna tuner affects only
the antenna(s) connected here, and only during trans-
mission.
Warning!
The 141V RF voltage (@200 W/50
Ω
) is applied to
the TX RF section of the transciver while transmitting.
Do not touch the TX RF section absolutely while trans-
mitting.
RX ANT IN Jack
The BNC jack provides output of the receiver signal
from the Antenna jacks, which are connected to the
“RX” side of the transceiver T/R switching circuitry.
The type-M jack is for a separate, receive-only antenna.
An antenna connected here can be used 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 ANT OUT” and “RX ANT IN” jacks.
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. Please refer to page 9 for other notes about
proper grounding.
µ-TUNE Jacks
These jacks are used for signal input/output of the op-
tional RF µTuning Kits.
ROTATOR Jack
This 6-pin MINI-DIN Jack accepts a cable connected
to a YAESU
G-800DXA / -1000DXA/-2800DXA (for
USA/EXP market) or
G-800DXC
/
-1000DXC/-
2800DXC (for European market) Antenna Rotator
(listed models are current as of early 2010). You may
control the antenna azimuth rotation (and rotation
speed) using the Function buttons on the front panel.
BAND DATA Jack
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.
PACKET Jack
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 15. The receiver audio level
at this jack is approximately 100 mVp-p (@600 Ohms).
