  • United Wireless Telegraph Type C tuner, went into production in 1907. The Type D Tuner based on this unit was put into production in 1908 and became the United Wireless standard receiver for both marine and land stations well into World War I. .

    This receiver has one two-slide coil and one single-slide tuning coil in a mahogany box. A carborundum detector with its potentiometer, and a shunt switch for shorting the detector during transmission, were mounted on top of the cabinet. The batteries were inside the cabinet.

    Tuning range was 200 to 2,000 meters.
