AF OUT Jack
This 3.5-mm, 3-contact jack provides dual-channel
low-level receiver output, for recording or external am-
plification. Peak signal level is 300 mVp-p at 10 k-
Ohms. TheVFO-A receiver audio is on the left chan-
nel (tip), and the VFO-B receiver audio is on the right
channel (ring). A stereo amplifier or recorder is rec-
ommended, to record each receiver's audio separately
when dual reception is enabled (audio from either re-
ceiver, or both, may be used via this jack). The front
panel [ AF GAIN ] knobs do not affect the signals at
this jack.
V-AF Jack
This 3.5-mm, 3-contact jack is used for connection to
the optional SM-5000 Station Monitor.
EXT SPKR Jack
This 3.5-mm, 2-contact jack provides receiving audio
output from the VFO-A and VFO-B receivers for an
external loudspeaker or speakers, such as the SP-2000.
Inserting a plug into this jack disables the internal loud-
speaker. Impedance is 4 ~ 8 Ohms.
E.ALC Switch
This slide switch is used for selecting the recovery time
of the ALC.. Set this switch to "1" position when this
transceiver connects to the optional VL-1000 Solid-
state Linear Amplifier.

ONNECTIONS
PTTJack
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.
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.
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.
TX GND Jack
This RCA 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 lin-
ear amplifier. To enable this jack, please set Menu item
"146 tGEn ETX-GND" to the "EnA" (Enable) selec-
tion.
The relay circuit of this transceiver used for this jack
is capable of switching AC voltage of 100 Volts at up
to 300 mA, or DC voltages or 60 V at 200 mA or 30 V
at up to 1 Amp.
