An antenna trimmer allows the rf circuit to be accurately peaked at any part of any
band. The rf gain control allows the sensitivity of the receiver to be adjusted to”
accommodate
both
weak
and
strong
received
signals.
The receiver operates on 115V 60 Hz ac power only and draws only 18 watts of power.
Any low impedance (50 to 75 ohm) antenna or transmission line may be connected to
the
convenient
antenna
terminals
at
the
rear
of
the
receiver.
Careful attention should be paid to the “Installation” and “Operation” sections of this
manual. These sections give information for the satisfactory operation of your Model 500
receiver.
The Model 500 has a very high degree of sensitivity needed to receive weak and distant
signals. Careless operation or poor installation of this high-sensitivity receiver may cause
an excessive amount of noise or background hiss. Careful adjustment of the tuning,
volume, and gain controls, as outlined in the previously mentioned sections, will keep
these undesirable effects to a minimum.
Installation
As mentioned earlier, proper installation goes hand-in-hand with correct operating
procedures to get maximum performance from your receiver. Read this section carefully
to become familiar with the correct installation of your receiver.
Location. The cabinet of the Model 500 is equipped with four small feet which are
suitable for placing the receiver either on a shelf, desk, or table. When you locate the
receiver, try to avoid excessively warm places, such as near radiators or heaters. Warm
locations
may
cause
the
receiver
to
drift
off
frequency.
Be
sure
to
allow
at
least
one
inch
clearance between the rear of the cabinet and the wall to give the receiver proper
ventilation.
Electrical Power. The Model 500 is transformer-operated and will operate only on
115
volt,
60
Hz
ac
power.
It
uses
18
watts
of
power.
If
you
are
in
doubt
about
your
power source, call your local power company before you plug the power cord into the
power outlet. Connecting the receiver to the wrong power source can cause serious
damage
and
costly
repairs
to
the
receiver.
Antennas.
The
antenna
input
of
the
receiver
is
designed
to
work
with
either
a
single
long-wire
antenna
(Fig.
1)
or
a
half-wave
dipole
or
other
resonant
antenna
with
transmission
line
impedances
from
50
to
75
ohms
(Fig.
2).
The
connections

The
long-wire
antenna
(Fig.

can
be
used
for
all
three
bands
in
locations
where
space
is
limited.
The

provides
much
better
performance
than
the
simple
long-wire
antenna.
This

This
type
of

antenna
and
may
be
used
in

Output
Connections.
The
Model
500
receiver
has
a
built-in
loudspeaker
so
no
other
output
connections
are
needed
for
operation.
To
use
headphones,
a
PHONES
jack
is
provided
on
the
front
panel.
This
jack
is
wired
to
disable
the
loudspeaker
automatically
when
headphones
are
plugged
in.
The
headphone
impedance
is
not
critical;
however,
for
maximum
output,
low-impedance
magnetic
phones
(S0-500
ohms)
should
be
used.
Since
no
direct
current
flows
in
the
headphone
circuit,
even
high
impedance
crystal
headphones
may
be
used.

Location
and
Function
of
Controls
Each
control
of
the
Model
S00
receiver
performs
a
definite
job
which
contributes
to
the
overall
performance
capabilities
of
the
receiver.
To
fully
appreciate
the
capabilities
of
the
receiver,
you
must
first
become
familiar
with
each
of
its
controls
and
the
effect
these
controls
have
on
receiver
performance.
This
section
gives
a
brief
description
of
the
various
controls
as
shown
in
Fig.
4.
The
next
section
takes
up
the
use
of
these
controls
in
more
detail.
Volume/Off
Control.
The
volume
control,
a
variable
resistor,
controls
the
gain
of
the
audio
signal
in
the
receiver.
In
the
full
counterclockwise
position
this
control
turns
off
the
ac
power
to
the
receiver.
With
power
on,
the
pilot
lamp
lights.
Clockwise
rotation
of
the
volume
control
turns
the
power
on
and
increases
the
audio
volume.
BFO
Switch.
The
BF
switch
turns
the
beat
frequency
oscillator
(BFO)
on
and
off.
In
the
CW
position,
the
BFO
is
turned
on
for
reception
of
CW
(telegraph)
and
SSB
(single
sideband)
signals.
For
receiving
AM
(amplitude
modulation)
signals,
the
switch
is
placed
in
the
AM
position
and
the
BFO
is
turned
off.
A
third
position
of
this
switch
(STBY)
mutes
the
receiver
for
standby.

respectively.
Gain
Control.
The
gain
control
is
a
variable
resistor
used
ta
vary
the
gain
(amplification)
of
the
first
i-f
anvplifier
stage.
It
is
used
primarily
for
CW
reception,
as
described
in
the
next
section.
Clockwise
rotation
of
the
control
increases
the
gain
of
the
i-f
amplifier
for
receiving
weak
signals,
PHONES
Jack.
The
PHONES
jack
accepts
a
standard
1/4”
two-conductor
phone
plug
for
headphone
reception.
Inserting
the
headphone
plug
automatically
disables
the
built-in
loudspeaker.
Tuning
Control,
This
control
is
a
variable
capacitor
which
determines
the
oscillator
frequency
for
each
of
the
three
bands.
It
is
used
to
tune
in
the
various
stations
on
each
band.
Antenna
Trimmer
Control.
The
antenna
trimmer
is
a
vanable
capacitor
connected
to
the
secondary
of
the
antenna
coil.
It
is
used
to
ensure
that
the
antenna
coil
is
accurately
tuned
to
the
desired
incoming
signal
and no
other.
wa

Operation
To
put
the
receiver
into
operation,
first
make
sure
the
receiver
is
plugged
in
and
a
suitable
antenna
connected.
There
are
three
modes
of
operation
of
your
Model
500
receiver
CW,
AM,
and
SSB.
The
following operating
methods
apply
to
any
of
the
three
bands.
However,
for
practice
purposes
it
is
suggested
that
the
40-meter
band
be
used
since
there
are
usually
a
number
of
CW,
AM,
and
SSB
stations
on
this
band
at
all
times
of
the
day
or
night.
CW
RECEPTION
1.
To
receive
CW
signals,
set
the
controls
as
follows:

2.
Starting
at
the
low
frequency
end
of
the
band,
rotate
the
tuning
control
clockwise
until
a
CW
signal
is
heard.
If
necessary,
reduce
the
gain
control
to
lower
the
volume.
Do
not
use
the
volume
control
for
this
purpose
for
CW
signals.
You
can
control
the
pitch
(tone)
of
the
signal
by
carefully
adjusting
the
tuning
control
for
the
desired
pitch.
3.
Rock
the
antenna
trimmer
back
and
forth
to
produce
maximum
output.
SSB
RECEPTION
The
procedure
for
tuning
in
an
SSB
signal
is
identical
to
the
previous
procedure
with
one
important
difference.
When
you
tune
in
the
signal
you
must
tune
very
carefully
for
maximum
intelligibility
of
the
speech.
For
very
strong
signals
you
may
have
to
reduce
the
setting
of
the
gain
control
considerably
to
produce
undistorted
speech.
A
little
practice
should
soon
make
tuning
in
SSB
signals
an
automatic
process.
AM
RECEPTION
1.
For
AM
reception,
set
the
receiver
controls
as
follows:

Reduce
the
setting
of
the
volume
control
as
necessary
to
maintain
a
comfortable
level.
Adjust
the
tuning
control
for
maximum output.
3.
For
very
strong
stations,
reduce
the
setting
of
the
gain
control
(counterclockwise)
to
prevent
distortion
of
the
sound.

However.
if
you

you
may
possibly
find
it
necessary
to
readjust
one
or
more
of
the
if
transformers
or
oscillator
coils
for
peak
performance.
This
is
due
to
individual
dilferences
in
wiring
from
one

another
and
amounts
to
very
small
adjustments
Factory

has
been
tampered
with
or
component
parts
have
been
replaced
in
the
i-f
or
oscillator
stages.
To
align
the
Model
500
receiver
you
will
need
a
small
screwdriver,
the
alignment
tool
supplied
with
this
receiver
and
a
signal
generator
covering
the
following
frequencies:
455
kHz,
3500
kHz,
7000
kHz,
21,000
kHz.
In
addition,
a
vivm
would
prove
useful.
although
it
is
not
absolutely
necessary
if
a
modulated
signal
source
is
used.
The
BFO
and
i-f
transformer
windings
are
resonated
with
a
fixed
capacitor.
The
resonant
frequency
of
each
winding
can
be
adjusted
by
turning
the
slugs
in
the
windings
with
the
special
alignment
tool
included
with
your
receiver.
So
that
you
can
easily
observe
how
far
you
have
turned
the
alignment
tool,
attach
a
piece
of
tape
to
the
center
of
the

CONVERTER
ALIGNMENT
There
are
two
ways
to
align
the
oscillator
and
antenna
coils
of
the
Mode!
500
receiver.
The
first
way
is
to
use
an
unmodulated
signal
generator
with
a
vtvm
connected
as
for
1-1
alignment
(Method
2).
The
second
way
is
to
use
the
output
from
a
transmitter
(crystal
controlled)
as
the
signal
source
rather
than
a
signal
generator.
If
you
use
your
transmitter
you
will,
of
course,
adjust
the
receiver
at
the
frequency
of
the
transmitter.
When
using
a
signal
generator,
use
the
frequencies
listed
in
Table
II
on
page
15.
I. Preset the controls as follows:
VOLUME/OFF ON
BFO AM

2.
Connect
the
signal
generator
to
the
antenna
and
ground
terminals
and
set
to
3.5
MHz
unmodulated.
Or:
Connect
a
short
lead
to
the
antenna
terminal,
set
the
tuning
control
to
the
transmitter
frequency
and
turn
on
the
transmitter
(connected
to
a
dummy
antenna.)
.
Connect
the
vivm
as
for
i-f
alignment.
4,
Rotate
the
tuning
control
until
you
get
a
maximum
reading
on
the
vivm.
Note
whether
the
diil'reads
above
or
below
3.5
MHz.
5.
Set
the
tuning
control
to
3.5
MHz
and
adjust
L4
(Fig.
5)
for
a
maximum
vtvm
reading.
If
the
dial
was
below
3.5
MHz
in
Step
4,
turn
L4
counterclockwise
to
align
the
oscillator.
If
the
dial
was
above
3.5
MHz
in
Step
4,
tum
L4
clockwise
to
align
the
oscillator.
6.
Adjust
LI
for
maximum
output
on
the
vtvm.
LI,
L2,
and
L3
are
adjusted
from
the
bottom
of
the
chassis.
7,
Adjust
the
converter
coils
for
the
remaining
bands
as
outlined
in
Table
H.
