INTRODUCTION
The Siltronix Model 1011D Single Sideband Transceiver is designed to be used in SSB or AM modes in the 10-meter amateur radio
band. In addition the 1011D is also a tunable receiver in the CB band.
Power input exceeds 300 watts P.E.P. on single sideband and 60 watts on AM. The Model 1011D includes automatic gain control
(AGC) and automatic level control (ALC).
The internal AC power supply permits fixed station or portable operation wherever 117 volts. 50-60 Hertz is available.
Export models for 208-220-240 volts are available on special order.
For 12-14 volts DC operation in mobile, marine, or portable applications, a DC converter unit, Model 14A is available. It attaches to
the back of the 1011D in place of the AC power cord connector. Its dimensions are only 1-1/2 x 3 x 4 in.
The Model 1011D generates a single sideband signal by means of a crystal lattice filter, and the transceive operation automatically
tunes the transmitter to the received frequency. Provisions are included in the transceiver for operation on either upper or lower side
band.
Two power receptacles on the rear panel provide 117 VAC to accessory equipment. One of the receptacles is connected through the
front panel power switch and the other is connected directly to the line.
CAUTION
Accessory equipment must not be plugged into the accessory receptacles when the model 14A, 12VDC power converter is in use.
Damage to accessory equipment may result.
A digital frequency indicator, Model FD-1011, is available for use with the 1011D. This accessory is powered from the accessory
receptacle of the 1011D and indicates the frequency, in megahertz, to which the transmitter or receiver is tuned, on an LED display
having five, one-half inch high digits. Installation requires only that mating connectors be plugged into connectors on the rear panel
of the 1011D marked “FD-1011 ACC”. The FD-1011 may also be powered from 12VDC in mobile installations.
CAUTION
Refer to the Operation Section, Page 9, before applying power to the transceiver. Failure to follow the Preliminary Checks procedure,
therein, will result in permanent damage to the Power Amplifier (P.A.) tube.
