Rozyna radio receiver

The Rozyna radio was designed and sold in 1962 in Warsaw. The distinguishing features of the radio are its small dimensions, achieved thanks to the use of miniature components and structure. The radio allows reception of radio waves in the short, medium and long wave bands, with the possibility of amplitude modulation. Due to the parameters achieved, its relatively low price, and small dimensions, the Rozyna was highly popular. It is a superheterodyne receiver powered from the mains through a built-in transformer, having three vacuum tubes. The device has a magnetoelectric speaker. Reception of radio frequencies is possible thanks to a built-in, static, directional, ferrite antenna. This means that in order to improve reception it is necessary to move the entire radio around, so that the antenna receives the signal in an optimum position. Manufacturer: Zakłady Radiowe im.
