During transmit, used to key a linear amplifier by
providing a switch to ground from a built-in relay.
Requires a standard audio (phono) plug.
@ ANT
Connect to an external antenna, an antenna tuner, or a
dummy load. Use a 50 ohm HF antenna and feed
system, with a PL-259 (M type) coaxial connector.
@) KEY
Connect a key for CW operation. Use a 3.5 mm
diameter plug.
Turn the transceiver power off before inserting the
plug.
The transceiver will momentarily transmit if the key is
inserted with the power on.
® EXTSP

diameter plug. This will disconnect the internal
speaker.
© Power Input DC 13.8 V
Connect to a 13.8 V DC supply to power the
transceiver. Use the supplied DC cable. This
transceiver draws less than 20.5 A (with an automatic
antenna tuner, less than 22.5 A) at maximum
transmitter output.
@ acc
Connect the optional automatic antenna tuner (AT-50
or AT-300). For details, refer to "AUTOMATIC
ANTENNA TUNER" on page 48.
®) GND
Connect a heavy gauge wire or copper strap between
the ground terminal and the nearest earth ground. Do
not connect the ground wire to either your house
electrical wiring, or gas or water pipes. A well
grounded transceiver will reduce the risk of
interference to television or broadcast radio receivers.
{t can also reduce receiver noise caused by static
discharges.
