i METER JACK [METER] (p. 19)

Outputs a signal showing received signal strength,

transmit output power, VSWR, ALC, speech com-

ression, Vd or Id level for external meter indica-

tion.

o STRAIGHT KEY J

ACK [KEY] (p. 17)

Accepts a straight key or external electronic keyer

output using a

⁄4 inch standard plug.

• [ELEC-KEY] on the front panel can be used for a

straight key or external electronic keyer. Deactivate the

internal electronic keyer in keyer set mode. (p. 45)

!0 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 p. 24 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 CONTR

OL 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 J

ACK [ALC] (p. 18)

Connects to the ALC output jack of a non-Icom lin-

ear ampl

iﬁer.

!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 se-

lected as

“ANT 1/R” or “ANT 2/R.” (p. 112)

• When no external unit is connected, “ANT 1” or “ANT 2”

must be selected.

!7 TRANSVERTER CONNECTOR [X-VERTER]

(p. 18)

Exter

nal transverter input/output connector.

Activated by voltage applied to [ACC 2] pin 6, or

when the transverter function is in use. (p. 24)
