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.
