ROT ROTATOR Jack
This 5-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
2006). 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 audio, for recording or external am-
plification. Peak signal level is 30 mVp-p at 10 kOhms.
EXT ALC Jack
This RCA input jack accepts negative-going 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.
