SBR (Société Belge Radio-electrique)

Société Belge Radio-electrique (SBR) is a Belgian radio brand.

On October 4, 1922, the SBR with its headquarters and workshop at 4 Egmontstraat in Brussels was created from two existing radio-electric companies: SIB (Société Indépendante Belge de télégraphie sans fil, founded in 1920 by Robert Goldschmidt) and SNR (Société Nationale Radio -electrique). Many members of these last two companies sat on the board of SBR. One of the earliest produced receivers from SBR, named "Radio Puzzle", was a modular type inherited from SIB. This consisted of several units and were connected to each other via terminal strips and wires. Many combinations were possible with this device, hence the name Radio Puzzle. The Radio Puzzle consisted of a receiver module with a loop antenna, a detection module, a high-frequency module and finally a low-frequency module with headphones. An additional module to control a spill writer was also available.

It was not until a few years later, in 1924, that the new SBR factory was established, located at 66 Ruisbroeksesteenweg in Uccle. In fact, SBR took over SIB's existing installations. The exhibition hall was located at 30 rue de Namur in Brussels. The headquarters remained at the same address.
