Information
                                    Sideband Engineers Inc. Model 33, is a single sideband,
suppressed carrier Transceiver designed specifically for use
on the Phone portions of the 80-, 40-, 20-, and 15-meter
amateur radio bands. Operation may be either upper or lower
sideband, selection being made through a front panel
control. Transmission is on the exact carrier frequency
being received, and there is no carrier shift in changing
from upper to lower sideband operation. Peak effective power
output exceeds 70 watts on 80-, 40-, and 20-meters, and 50
watts on 15-meters.
The Transceiver is self-contained-only a microphone and an
Antenna are required for operation from a nominal 117-volt
a-c power source. Operation is possible from a mobile or
portable source through use of a transistorized d-c to a-c
inverter which is available as an accessory. Provisions-have
been made for the addition of a VOX-audio compression unit
which is also available as an accessory.
Basic circuitry of the SB-33 is solid-state. Transistors are
utilized in all low-level stages, vacuum tubes are used in
only the Transmitter driver and power Amplifier stages. The
use of bilateral Amplifier and mixer stages which amplify in
one direction in transmit and in the other direction in
receive, permits use of a single bandpass circuit train.
Duplication of circuitry is eliminated, and performance is
optimized through use of common circuit elements in both
receive and transmit modes.
A unique bandswitching and exciter tuning control allows
both functions through a single front-panel control knob.
Other controls and adjustments are held to a minimum.
Stability and selectivity are exceptionally high. The design
is such that the few heat producing components are isolated
from the frequency determining elements. All voltages to the
low-level stages are regulated and the VFO is temperature
compensated. Selectivity of 2.1 kc at 6 db is achieved on
both transmit and receive through use of a COLLINS
mechanical filter.
The entire one-package installation is less than one-half
cubic foot, weighs approximately 15 pounds, and is entirely
self-contained, including Power Supply and speaker. Because
of the revolutionary new circuitry, (patents pending), and
unique design, you have the smallest, best performing SSB
Transceiver available today at any price.
