Information
This receiver is a commercial grade communications receiver
employing the most up to date solid state devices and
circuitry. It provides continuous coverage from 10 kHz to 30
MHz with the received frequency displayed on a digital
readout to the closest 100 Hz. All frequency injections of
the receiver are controlled by a phase-locked digital
synthesizer which allows incremental frequency selection in
10, 1 and 0.1 MHz steps. The remaining 0 to 0.1 MHz is
continuously adjustable by a highly stable variable
oscillator from the fine tuning knob on the front panel.
Modular construction on easily accessible printed circuit
boards is used throughout this receiver. The generous use of
dual gate MOS-FET transistors in this receiver’s circuitry
contributes to its superior intermodulation, wide AVC
dynamic range and overload performance. The front panel
controls allow the operator to select frequency, AM or SSB
detector, I.F. bandwidth, AF gain, BFO pitch, fast or normal
AVC, manual RF gain, and Drake’s highly effective series
gate noise blanker. Independent sideband (ISB) is a built-in
feature of the receiver. Separate I.F. crystal filters, I.F.
amplifier, detector and audio output circuits allow two
simultaneous communications channels (USB and LSB) to be
employed on one frequency assignment,
doubling the information receiving capacity. The receiver
may be powered from 115 or 230 VAC, 50 to 420 Hz. An
inverter is available, as an accessory, for operating the
receiver from a 12 or 24 VDC source.
