The R-530 communications receiver from Galaxy Electronics was solid-state and synthesized. It used modular construction, some of which can be seen in this “topless” photo. The R-530 covered .5–30 MHz in 500 kHz ranges and had 1 kHz calibration on its tuning dial. The standard 9 MHz IF filter was 2.1 kHz, with .5, 1.5, and 5 kHz filters available as options.
