The Amateur Communications Receiver is a precision-engineered instrument designed to meet the high standards of Amateur performance. It offers widely adjustable selectivity and exceptionally high sensitivity to bring in solid QSO’s. The frequency range covers standard, medium, and short-wave broadcasts, including all Amateur bands from 80 through 10 meters. By using multi-purpose tubes, the 7-tube superheterodyne circuit provides performance equal to an 11-tube Receiver. To simplify the tuning of the crowded shortwave stations, the Receiver uses a separate bandspread tuning capacitor. It is calibrated for the five Amateur bands (80-10 meters), and is also helpful for bandspread tuning any part of the frequency spectrum. The main tuning dial covers 540 kc to 31 me in 4 ranges. The civil defense frequencies are clearly marked, and each Amateur band is indexed. Both main and bandspread dials have vernier mechanisms for smooth, easy tuning. Other features are a highly effective noise limiter and a built-in Q-Multiplier to peak desired signals or to null undesired signals and interference. A constant-running high-frequency Oscillator with voltage-regulated B-j- supply, and extra-heavy chassis design contribute to the rock-like stability of this fine Receiver. Frequency stability is maintained over a wide temperature range. Two printed circuit boards assure wiring accuracy and uniformly high performance of every Receiver kit. All critical wiring is already done— there is no problem of lead dress. Assembly has been further simplified by use of a unique printed-circuit bandswitch.
