EAR ANEL
ROT ( ROTATOR ) Jack
This 6-pin MINI-DIN Jack accepts a cable connected
to a YAESU G-800DXA/-1000DXA/-2800DXA An-
tenna Rotator (listed models are current as of early
2009). You may control the antenna azimuth rotation
(and rotation speed) using the Function buttons on the
front panel.
BND ( 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).
RTTY Jack
This 4-pin input/output jack provides connections for
an RTTY terminal unit. Pinout is shown on page 15.
The receiver audio level at this jack is at a constant
100-mV (@600 Ohms) level. FSK keying at this jack
is accomplished by a closure of the SHIFT line to
ground by the terminal unit.

PTT Jack
This RCA input jack may be used to provide manual
transmitter activation using a footswitch or other
switching device. Its function is identical to the [ MOX ]
button on the front panel. The same line is available at
the PACKET and RTTY jacks for TNC control. Open-
circuit voltage is +13.5 VDC, and closed-circuit cur-
rent is 5 mA.
MIC ( PATCH ) Jack
This RCA input jack accepts transmitter audio - either
AFSK or voice - for transmission. This line is mixed
with the microphone audio input line, so the micro-
phone should be disconnected if using this jack and
mixing is not desired. The optimum impedance is 500
~ 600 Ohms, and the nominal input level should be 5
mV.
TRV Jack
This RCA jack provides a low level RF output for use
with a transverter. Maximum output is approximately
–10 dBm (0.1 mW) at 50 Ohms.
REC Jack
This RCA jack provides low-level receiver audio out-
put and transmit (monitor) audio (requires the [ MONI ]
button is turned on), for recording or external amplifi-
cation. Peak signal level is 30 mVp-p at 10 kOhms.
