Informações:
                                    The SSB-100F is a medium power, single sideband suppressed
carrier Transmitter designed for simplex telephone or
telegraph operation. It may also be operated with carrier to
make it compatible with existing amplitude modulated
systems. The SSB-100F covers all amateur frequencies between
3. 5 and 29.5 megacycles in 8 bands, selected by a front
panel switch. The Peak Envelope Power output is 100 watts.
The occupied bandwidth is 3 Kc as opposed to 6 Kc with a
conventional AM or DSB Transmitter, and either sideband is
selectable by a switch on the front panel.
2. FEATURES
The SSB-100F has been designed to provide the utmost in
flexibility without compromising the performance
characteristics which up to now were available only in
highly specialised equipment. Among the features that
contribute to the high grade performance of this Transmitter
are the following:
A. Highly stable filter type exciter section providing a
minimum of 50 db attenuation of the unwanted sideband and
carrier.
B. Selectable sideband operation, front panel controlled.
C. Audio shaping for maximum intelligibility, pleasing
quality and conservation of valuable spectrum space.
D. Voice controlled break-in operation with speaker quieting
circuit.
E. Built-in highly stable variable frequency Oscillator.
F. Inverse RF feedback for low distortion,
G. Compact design, completely self-contained including all
controls, circuits for Receiver muting and Antenna change
over (external Antenna relay required).
H. Built-in one-inch oscilloscope for continuous monitoring
of the linearity of all mixers and amplifiers between
exciter and power output stage.
I. Complete ham band coverage with dial calibrated in 10 Kc
increments, readable to
2 Kc.
J. Tuning rate is constant for all bands.
K. Carrier insertion and audio level are independently
adjustable.
L>. While the output impedance is nominally 52 ohms, an
adjustable loading network permits matching into lines of
Other impedances, even with moderate standing wave ratio.
M. Provision is made in voice control circuits to operate
external relays, etc.
