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. The VFO-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). 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 the jack disables the internal loud-
speaker. Impedance is 4 ~ 8 Ohms.
E.ALC Switch
This slide switch is used to select the recovery time of
the ALC. Set this switch to the "1" position when the
transceiver is connected 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 is closed to ground while the transmit-
ter is engaged. It may be used for control of a periph-
eral device, most typically a linear amplifier. To en-
able the jack, set Menu item "172 TGEN ETX-GND"
to the " ".
The relay circuit used for this jack is capable of switch-
ing an AC voltage of 100 Volts at up to 300 mA, or a
DC voltage of 60 V at 200 mA, or DC 30 V at up to 1
Amp.
