METER JACK [METER] (p. 19)
Outputs a signal showing received signal strength,
transmit output power, VSWR, ALC, speech
compression, V
d
or I
d
level for external meter
display.
o
STRAIGHT KEY JACK [KEY] (p. 17)
Accepts a straight key or external electronic keyer
output using a standard
1
⁄
4
inch plug.
• [ELEC-KEY] on the front panel can be used for a
straight key or external electronic keyer. Deactivate the
internal electronic keyer in the keyer set mode. (p. 49)

ACCESSORY SOCKET 2 [ACC 2]
!1
ACCESSORY SOCKET 1 [ACC 1]
Enable connection of external equipment such as
a linear amplifier, an automatic antenna selector/
tuner, a TNC for data communications, etc.
• See page 26 for socket information.
!2
TUNER CONTROL SOCKET [TUNER] (p. 18)
Accepts the control cable from an optional AH-4
HF/50 MHz AUTOMATIC ANTENNA TUNER
.
!3
SEND CONTROL JACK [SEND] (p. 18)
Connects to ground when transmitting to control an
external unit, such as a non-Icom linear amplifier.
NOTE: T/R control voltage and current must be
less than 16 V DC/0.5 A (or 250 V AC, 200 mA
with MOSFET switching).
!4
ALC INPUT JACK [ALC] (p. 18)
Connects to the ALC output jack of a non-Icom
linear amplifier.
!5
RECEIVE ANTENNA OUT [RX ANT– OUT]
!6
RECEIVE ANTENNA IN [RX ANT– IN]
Located between the transmit/receive switching
circuit and receiver’s RF stage.
Connects an external unit, such as preamplifier or
RF filter, using RCA connectors, if desired.
In this case, the antenna connector must be
selected as “ANT 1/R” or “ANT 2/R.” (p. 120)
• When no external unit is connected, “ANT 1” or “ANT 2”
must be selected.

TRANSVERTER CONNECTOR [X-VERTER]
(p. 18)
External transverter input/output connector.
Activated by voltage applied to [ACC 2] pin 6, or
when the transverter function is in use. (p. 26)
