6. The Transceiver should be connected to a good Preset the front panel controls as follows (CW means fully
ground. clockwise.
CCW means fully counterclockwise):
7.
If
a
power amplifier
is
being used,
A.
The amplifier's ALC output should be
connected to the ALC socket on the rear panel.
B.
Providing the amplifier's transmit-receive relay
is
the type which
is
activated by grounding the
relay coil, the amplifier's relay coil connection
should be connected to pin
8
of the ACC socket.
Pin
9
of the ACC socket must be grounded to
complete the circuit.
8.
If an external receiver
is
used which has a mute circuit
which must be grounded to allow the receiver to
operate, this circuit can be connected to pin 10 of the
ACC socket. Pin
9
must be grounded. This will ground
the mute circuit in the receive mode.

RECEIVING
The
receiver is broad banded and no preselector tuning
is
required. For best results, the antenna should be designed
for
a
50
SZ
impedance, or an antenna coupler should be used
to match the antenna's impedance to 50
a.
1. Check the connections in "Initial Actions" (Page 259).
2. Connect the transmission line to the ANT socket on
the rear panel.
3.
The rear panel slide switch should
be
at COM when
you are receiving and transmitting on the same
antenna.
4.
Depress the ALC and the
ON
buttons.

Depress the USB, LSB, or CW button.

7.
If you will use VOX operation, depress the VOX
button and place the microphone in the position
it
will occupy during normal operation, and tune in a
strong station. The receiver will usually cycle on and
off with the voice peaks
of
the strong station. Turn
the ANTI-VOX control clockwise (as viewed from the
rear) until the cycling action ceases. Do not advance
the control beyond this point.
8.
The AGC switch can be moved to another position,
although most SSB operators prefer SLOW.
CW
operators may prefer FAST or OFF.
9.
Depress the NB button to activate the noise blanker, if'
one
is
installed.
10.
If you use a separate receiving antenna, connect
it
to
the REC socket on the rear panel and set the adjacent
slide switch at REC. Transmission will always use the
antenna connected to the ANT socket.
