UNPACKING INSTRUCTIONS
After unpacking the receiver, carefully check for possible damage which may have occurred in transit.
Should any signs of damage be apparent (tubes broken, case dented, etc.), notify the store from which
it was purchased. If the unit was shipped to you, also file a claim with the carrier,
The following accessories should be included in the carton:
1 Standard Phone Plug
1 Jumper Plug (for the auxiliary control socket)
INSTALLATION
POWER SOURCE
The receiver is designed to operate from a 90-125 volt, 50-60 cycle AC power source, DO NOT OPER-
ATE FROM A DC SOURCE, The receiver is equipped with a voltage selector switch (located within
the unit), This switch should normally be left in the 117V position.
SPEAKER CONNECTION
A three-terminal strip marked OUTPUT is provided at the rear of the receiver for speaker connections.
Any PM speaker with either 4 or 8 ohm impedance can be used, Simply connect one lead to the ground
terminal "0" and the other lead to the terminal that corresponds to the speaker impedance, ‘The output
power of the receiver is sufficient to drive a 4-12 inch PM speaker adequately.
HEADPHONES
A standard phone jack is provided on the front panel of the receiver for headphone reception, Low im-
pedance (8-16 ohms) headphones are recommended for optimum results. Insertion of a phone plug into
the jack automatically disconnects any speaker attached to the 8 ohm output terminal, ; .
ANTENNAS
The terminals marked "Al", "A2", and "E" at the rear of the receiver are for antenna and ground con-
nections, Either of the following two types of connections can be used to obtain satisfactory results,
INVERTED L ANTENNA
The inverted L type of antenna will provide satisfactory performance over the entire tuning range.
Simply short Ae and E with a jumper wire, and connect one end of the antenna wire to Al, For good
reception, the antenna wire should be placed as high as possible and 50-100 feet long (see Fig. 1). In
some instances, a wire connected from terminal ''E'' to a water pipe may improve reception,
DOUBLET ANTENNA
A doublet antenna will give excellent results, especially on amateur bands. A 75 ohms balanced trans- . :
mission line should be used (as shown in Fig.2). Since the doublet antenna provides optimum perform- i 4
ance only at a given frequency, it should be cut to the length for the most often used band of frequencies.
The overall length of a doublet antenna can be determined by using the following formula: j

Since the doublet antenna displays directional properties broadside to its length, it should be oriented “al
in such a manner that maximum signal pickup can be realized, oe
“nd
When using either a balanced transmission line or a twisted pair, the leads connect to terminals "Al" ee
S and ''A2" respectively, and the jumper wire between "A2" and "E" is removed. A height of 30-50 feet r
e is” recommended for good reception of weak signals, — t
"| FUSE
. A 2 amp fuse is located at the rear of the receiver. To remove it, unscrew the spring loaded cap. Re-
place only with one of a similar rating.
AUXILIARY CONTROL
‘ A socket in the back of the’ receiver allows simultaneous control of this receiver with a transmitter. An
external switching device can be constructed so that the receiver will be inoperative during periods of
mee transmission, In this case, the FUNCTION switch is
AUXILIARY SOCKET placed in the SEND position. The external switch is
attached to the 5-pin plug so that pins 3 and 2 (see
Fig. 3) will be connected when signal reception:is de-

A
Q-Multiplier
provides
the
additional
selectivity
often
required
for
optimum
reception
of
signals
in
the
congested
short-wave
bands,
In
your
receiver,
the
Q-Multiplier
circuit
serves
a
dual
function
-—
Q-Multiplier
and
BFO.
For
CW

BFO,
The
circuit
may
be
employed
as
a
Q-Multiplier
during

if
conditions
require
the
use
of

A
little
experience
in
using
the
Q-Multiplier
will
be
necessary
for
optimum
results
under
different

ceiving
conditions.
In
the
hands
of
an

When
the
Selectivity
control
is
used
to
increase
selectivity
during
Q-Multiplier
operation,
(as
described
previously),
the
sharp
peak
produced
can
be
moved
around
within
the
IF
pass
band
by
means
of
the
BFO-Q-MULT
-FREQUENCYSCONTROL
to
reduce
or
eliminate
interference
from
adjacent
signals.

USING THE CIRCUIT AS A Q-MULTIPLIER
Initially, all controls on the receiver should be set to the positions indicated in the chart for AM set-
tings. Tune in desired station. Set SELECTIVITY to the fully counter-clockwise position and FUNC-
TION to 'Q-Mult'', Increase AF gain if necessary. Advance the SELECTIVITY control until the de-
sired degree of selectivity is obtained. The point of maximum selectivity is reached just before the
circuit breaks into oscillation. The BFO-Q-MULT FREQUENCY control may now be adjusted to pro-
vide a reduction, or to eliminate, any adjacent channel interference.
USING THE CIRCUIT AS A BFO
Initially, all controls should be set as indicated in the chart for CW or SSB operation, Under these
conditions the BFO-Q-MULT FREQUENCY control is used to vary the pitch (CW) or for clarity of
signal (SSB), The SELECTIVITY control remains permanently in the CW-SSB position for CW or
SSB reception,
TUNING
The main tuning and bandspread dials are calibrated in megacycles and contain special markings to
simplify tuning. The major amateur radio bands are contained in the 1.6 to 4,8, 4.8 to 14.5 and
10.3 to 30,00 megacycle bands, The location of each amateur band is indicated by heavy white scale
lines on the main tuning dial. The circled letter or letters which appear with each band indicate the
bandspread scale to be used, Calibration of the main tuning scales is correct when the bandspread
pointer is set at 100 on the LOGGING SCALE.
Bandspreading on the amateur bands is carried out in the following manner: Set the bandspread pointer
initially to 100 and the main tuning pointer directly over the circled letter for the band to be tuned. In
some cases the band is split between two such letters, For example, B] and B2 together cover the
range of 7,0 to 7,35 megacycles — Bl from 7.0 to 7.17, B2 from 7.17 to 7.35 megacycles, The cali-
brated bandspread scale which is used is indicated to the right and left-hand side. Thus, if the main
tuning pointer is set over Bl, the bandspread scale in use is the one marked Bl, the fourth one down,
Tuning is then accomplished solely with the BANDSPREAD control.
Short-wave bandspreading, for other than amateur bands, is accomplished by setting the bandspread
pointer at 100 on the Logging Scale and the main tuning pointer at the high end of the short-wave band
to be tuned, Rotate the bandspread control to tune over the band. Moving the bandspread pointer to-
wards O on the logging scale subtracts from the frequency indicated on the main tuning scale. Logging
of short-wave stations is possible by noting the readings on both the Main Tuning and Logging Scales,
S- METER READINGS
The S-Meter provides a means of measuring the relative strength of incoming AM signals, Relative
readings are only correct when the IF GAIN control is fully clockwise, Measurements are read in
S units from | to 9 and in decibels above S9 from 0 to 40db, The circuit is disabled when the MVC/
AVC switch is in the MVC position.
A ZERO ADJ control at the rear of the receiver is provided for zeroing the S-Meter electrically. This
adjustment is made with the antenna disconnected, IF GAIN control at maximum and AVC on,
ANTENNA TRIMMER
The ANT TRIM control, adjustable from the front panel, acts as a compensating capacitor to permit
optimum matching of the receiver to the antenna at all frequencies, Initially, the control should be set
to its mid-position (the dot on the front surface of the knob at 12 o'clock position). The control should
always be adjusted for maximum background noise. Each setting will be good only over a limited range
of frequencies, The trimmer should therefore always be readjusted after tuning to the general area
where the expected signal is to be found,

on signal, This antenna’ control setting is satisfactory while operating over a limited frequency range.
If excessive spurious noises such as those caused by auto ignition make reception difficult, place the
ANL OFF switch to the ON position. The automatic noise limiter should be used only when necessary,
since it tends to reduce the overall efficiency of the receiver.
If interference from nearby stations makes reception difficult, the Q-Multiplier may be employed to
minimize or eliminate the interference, Since the use of the Q-Multiplier results in a narrower band-
width it should only be employed when interference is severe and where maximum fidelity is not re-
quired,
CW OPERATION .
The control settings required for the reception of code signals are indicated in the chart. AVC is
switched off and the IF GAIN control is used as a volume control. Tune signal to zero beat. The
BFO-Q-MULT FREQUENCY control should then be adjusted on either side of white dot for desired
pitch,
SINGLE SIDE BAND OPERATION
The settings of controls for SSB reception is essentially the same as for CW (see chart), The BFO
frequency however, is used in this case for carrier reinsertion. AVC is switched off and the IF GAIN
control used to adjust the level. Tune station in with BANDSPREAD control and then adjust BFO-Q-
MULT
FREQUENCY
control
for
clarity
of
speech.
Slight
readjustment
of
the
BANDSPREAD
may
be
necessary to provide best audio quality.
SHORT-WAVE LISTENING
On
the
short-wave
frequencies
are
to
be
found
radio
stations
transmitting
from
all
over
the
world,
Many
of
these
stations
provide
English-language
broadcasts.
The
frequencies
on
which
the
majority
of
short-
wave
broadcast
stations
operate
are
found
in
the
two
upper
bands
of
your
receiver
(4.8
to
14.5
mega-
cycles
and
10,5
to
30
megacycles),
A
characteristic
of
short-wave
is
that
reception
varies
with
the
time
of
day,
the
season
of
the
year
and
with
weather
conditions,
In
order
to
