A2516 Double conversion ham band receiver. It utilizes crystal controlled dual conversion circuitry and covers the 80, 40, 20, and 15 and 10-meter bands in addition to WWV at 10 MHz. It receives AM, SSB, and CW. The dial features an anti-backlash double gear construction. It is direct reading down to 1KHz. Precise tuning of all signals including SSB is assured by the large, geared down dial speed ratio of 28:1. Superior selectivity performance is obtained by the use of a mechanical filter in the IF circuitry. The VFO circuit is equipped with convenient output terminals so that it can also be used as a VFO for the transmitter. 7 tubes & semiconductors. The receiver’s physical dimensions are 13”W x 7”H x 10” D and weighs 18 pounds. Production year 1969-1971. Made in Japan. Supplementary photos
