							Introduction     1
The SW2 is a microprocessor controlled, synthesized,
shortwave receiver with continuous coverage capability
from 100 kHz through 30000 kHz which includes the
AM broadcast, Amateur, CB and shortwave bands.  The
SW2 offers good sensitivity, selectivity, dynamic range
and features that permit easy tuning of desired stations.
Conveniently located front panel controls allow for rapid
tuning to a particular frequency.  The SW2 is easy to
use.  The operating frequency can be tuned via a tuning
wheel,  
 /  tuning buttons, or by direct numeric
entry.
Reception modes include Lower Sideband (LSB), Upper
Sideband (USB), AM in the Shortwave and AM broad-
cast band.  For the Shortwave and AM broadcast bands,
a selectable sideband synchronous detector (SYNC)
allows for enhanced reception by eliminating or reduc-
ing distortion due to fading signals.The RF Gain is adjustable via a front panel control.  Dual
antenna input terminals on the rear panel provide
versatile and practical connection of either a coaxial 50
Ohm feedline or wire antenna connection to the
receiver.  A front panel LED display shows the receive
frequency.   Relative Signal strength is indicated by an
LED bar graph.  Mode of operation and connection to a
source of AC (or DC) power are indicated by additional
LEDs.  The receiver can be operated from the supplied
AC Adaptor which provides 12 VAC power, or from a
nominal 12 VDC power source.
The receiver allows for 100 independent, programmable
memories.  These memories do not require battery
backup and are thus unaffected by power interruptions.
All parameters associated with a particular memory
channel are stored including the frequency, mode, and
detector mode.  A few popular channels have been
preprogrammed.  Any memory channel can be pro-
grammed as desired.

AM
SYNC - AM SYNC  - Press to select the AM mode of
operation.  The AM indicator lights.  Successive depres-
sions toggles the synchronous detector on (AM and SYNC
indicators lit) and off.  For a detailed operation description,
see AM SYNCHRONOUS OPERATION in the GETTING
STARTED section of this manual.
SSB - SSB - Press to select the SSB mode of operation
(AM SYNC must be turned off).  Successive depressions
select alternately the ‘LSB’ or ‘USB’ modes as displayed by
the corresponding indicator.  For a detailed operation
description, see SSB OPERATION in the GETTING STARTED
section of this manual.
3) VOLUME - Turn this control clockwise to increase the
volume setting.  Turn this control counterclockwise to
reduce the volume setting.
4) RF GAIN - This control adjusts the RF gain of the
receiver and is normally set for the fully clockwise position.
Turn the control counterclockwise, as required, to reduce
the receiver gain for reception of strong signals.
5) SPEAKER - This is the opening for the internal speaker
of the receiver.
6) HEADPHONE JACK - This connector accepts a 1/8
stereo/mono headphone connector.  Reception is monau-
ral only. 1) Tuning (VFO)*- The tuning wheel and the 
 / 
buttons are the primary tuning controls of the receiver.
Clockwise rotation of the dial increases frequency in 50 Hz
steps and counterclockwise rotation decreases frequency
in 50 Hz steps.  The  
 /  buttons increment and
decrement the frequency in 5 kHz steps.  Press and hold
the
 or  and the rate of 5 kHz steps will increase.
*The VFO (Variable Frequency Oscillator) represents the
normal tuning mode of the receiver.
2) Program Buttons

1) 50 Ohm SO-239 Connector - This antenna input is a
50 Ohm, S0-239 coaxial input requiring a mating PL-259
connector.  This input would typically be used as the
primary antenna input.   Antennas such as dipoles, trap
dipoles, verticals and beams will provide the best results
depending upon the desired receiving frequency.
2) 50 Ohm Antenna Wire Screw Terminal - This
antenna input is a 50 Ohm screw terminal type requiring
bare wire from an antenna to be compressed under the
screw heads.  An antenna such as a random-length wire will
provide the best results.
3) GND (ground) Connection - This is the point from
which the receiver may be grounded in order to improve
reception when using, for example, a random length
antenna.
4) EXTERNAL SPEAKER - This connector accepts a
1/4 stereo/mono audio jack.  Reception is monaural only.
Do not ground either speaker lead.

4) 
METER -  Lights in the VFO mode to indicate the
Shortwave band designators that define a range of
frequencies for each band.  Refer to the Shortwave
Meter Band Designator Entry section of this manual.
5) POWER - Indicates that the AC Adaptor is connected
and plugged into an AC wall outlet.
6) LSB / USB -  LSB  Indicates that the Lower sideband
mode of detection is on.  USB indicates that the Upper
sideband mode of detection is  on.
7) AM / SYNC -  Indicates that the AM mode of
reception is on.  If SYNC is also illuminated, then the
synchronous AM mode of detection is on.  With SYNC
active, select USB or LSB for best reception.

UNPACKING - Carefully remove the SW2 and
included AC Adaptor wall transformer from the
shipping carton and examine them for evidence of
damage.  If any damage is noted, immediately contact
the transportation company responsible for delivery or
return the unit to the dealer from whom it was
purchased.  Keep the shipping carton and all packing
material for the transportation company to inspect.
The original carton and packing material should be
retained for repackaging should it be necessary to
return the receiver.  Inspect the packing material for
any accessories or printed material before storing the
box.
LOCATION - Location is not critical.  For fixed
locations, the SW2 should be operated from the AC
Adaptor.  Keep curtains and other flammable material
away from direct contact with the AC Adaptor to avoid
overheating the transformer which could result in
failure or fire.
FIXED INSTALLATION - After unpacking the unit,
connect the antenna system to the appropriate antenna
input. Connect system ground to the screw terminal
marked ‘GND’.   Plug the output cable of the AC
Adaptor into the ‘POWER INPUT’ connector on the
rear panel of the receiver.  Plug the AC Adaptor into a
source of 120 VAC, 60 Hz power.  Refer to Figure 2
for the diagram of a typical fixed installation.
ANTENNA REQUIREMENTS - Basic type
Connect a single wire lead-in to the ‘50 Ohm’ screw
terminal on the rear panel of the receiver.  This “lead-
in” wire and antenna can simply be one end of the
supplied 30 feet piece of wire.  The wire can be
distributed along an attic, out the window, or across
the room, for example.  The end that connects to the
‘50 Ohm’ screw terminal must have its insulation
stripped back so that a good electrical connection is
made between the wire and the screw terminal.
Alternatively, a 50 Ohm coaxial cable feedline from a
dipole, vertical or beam type antenna should be
connected to the rear panel ‘50 Ohm’ SO-239 coaxial
type antenna connector.  A mating PL-259 connector
on the receiver end of the coaxial cable is required, in
this case.
NOTE: Disconnect the AC Adaptor and antenna wire
from the receiver if the unit will not be used for an
extended period of time or if a storm containing
damaging lightning is likely.OPERATION FROM 12 VDC VEHICLE SUPPLY -
Observe proper polarity connection between the
vehicle lighter or accessory socket and the coaxial DC
power plug (5.5 mm O.D., 2.1 mm I.D.) which is
intended for connection to the SW2 power socket.
The exposed outside metal shell of the 5.5 mm power
plug is the - (Negative) connection to the SW2 rear
panel connector socket.  The inside metal contact
surface is the + (Positive) connection to the SW2
rear panel connector socket.
