HEADPHONE
KEY
For
headphone listening,
plug your
headphones into
the
HEADPHONE
jack. The
speaker is
automatically
cut
off
when a plug is
inserted into the
HEAD-
PHONE
jack.
Connect
your telegraph key or keyer to the phono
socket marked KEY. If one contact of
your
key con-
nects to its frame, be sure to connect that lead to
the outer
shell of the phono jack. NOTE: There is
a positive voltage present at this jack.
FRONT
PANEL
CONTROLS
Pictorial
7-2
(Illustration
Booklet,
Page
36)
shows
the
front
panel
switches and
controls, and
briefly
describes
their
function.
The
following
paragraphs
discuss
the
use of these
controls
in
normal opera-
tion. As you
read
this
discussion, set
each
switch
and
control to the
indicated
position. Be sure
you
have
connected a
power
source to
the DC
POWER
connector on
the rear
panel and
have
turned on the
power
source.
AF
GAIN/OFF
—
Turns the
Transceiver
off and on
and sets
the audio
level
for comfortable
listening.
Rotate the
AF GAIN
control
clockwise to
about the
mid-point.
You
can
readjust this
control later if
the
audio
level is too
loud or too
soft.
BAND
switch
—
Selects
the band
for
receiving and
transmitting. These
are the
80-, 40-,
20-, and
15-
meter bands
for the
basic
Transceiver, and also
in-
clude
the 30-,
17-,
12-, and 10-meter
bands if you
have the
Model
HWA-9
Accessory installed.
Set the
BAND
switch
to
the band you
desire.
SELECTIVITY
—
Selects
wide or
narrow selectivity
as
an aid in tuning
out unwanted
signals on either
side of the
desired frequency.
Set
the
SELECTIVITY
switch to WIDE for now.
You
can later
change to
NARROW to
eliminate adjacent
channel
signals.
RIT
—
This control
allows
you
to tune your receiver
to a
frequency that
is
up
to 1 kHz
above or below
the
transmitter
frequency.
Set
the
RIT
control
to its
midposition
(detent).
TUNING
DIAL
—
Selects the
receive
and
transmit
frequency.
This
dial is
calibrated
in divisions
from
0
to 250,
with
each
small
mark
indicating
5
kHz
and
each
longer
mark
indicating 10
kHz. Thus,
on
the
80-meter
band,
for
example, a
tuning dial
setting
of
zero
corresponds
to a
frequency
of 3.500
MHz,
while
one
small
division
above zero
corresponds
to
3.505
MHz, etc.
Use
the
TUNING
DIAL
to tune
in a
station. Then
calculate
its
frequency by
adding the
dial
divisions
to the
band's
base
frequency.
RELATIVE
SIGNAL
—
This meter
is marked
0
to
60 and
indicates
relative signal
level
in S-units for
received
signals, and
relative
power
when
transmit-
ting.
CW
LEVEL
—
Adjusts the
level
of RF output
sup-
plied to
the
antenna.
Key
the
transmitter
and
adjust the
CW LEVEL
con-
trol
to
the
point
where
the
meter
indication just
stops
increasing.
Never,
however,
adjust this
control
so
the
RELATIVE
SIGNAL
meter
indicates
higher
than
40. Then
release
the key.
NOTE:
An indication
of 40
(half
scale on 10
meters)
results
in rated
power
output
(approximate).
Your
Transceiver
is
now ready
for
"on-the-air" oper-
ation.
Review the
preceding
operating
control de-
scriptions
and
become
familiar
with them by
tuning
in
different
stations
and trying to
make
contact.
This
completes
the
"Installation
and
Operation."
