Detefon RD sII detector radio receiver3D Model
In 1929, Polskie Radio SA launched a campaign promoting radio reception, driven by the desire to reach the remotest places in Poland with its programming. The receiver to effectively promote this medium throughout Poland had to fulfil a list of requirements. It was expected to enable reception of radio stations in the Polish backcountry. At the same time, it had to be simple to operate and durable. In the light of the general poverty of the society, the originators of the campaign also proposed the condition of low price. The first result of the work on the fulfilment of such expectations was a detector receiver – the Detefon. Receiver with all its equipment (earphones, antenna, antenna switch with surge arrester, isolators for hanging the antenna on, etc.) cost 39 zlotys, while a vacuum tube receiver cost several hundred zlotys at the time.
