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.
