  • The Northwestern Radio Manufacturing Company's Model SR-1 Regenerative tuner cover the 160-900 meters wavelength range. The primary circuit of the receiver consisted of a variable inductance in series with the antenna tuning capacitor. The switch controlling the tapped inductance was on the back of the panel. An antenna capacitor connected across the front binding posts in parallel with the primary coil allowed the listener to receive lower frequencies with a shorter antenna. The secondary circuit is tuned by the SR-7 Variometer connected in series with the SR-8 Variocoupler. When shunted by a small fixed capacitor furnished with each receiver, the secondary circuit allowed reception of maritime stations on long wavelengths. Regeneration resulted by tuning the plate circuit with a second SR-7 variometer.
