classic valve receiver radio, Lille Braderie, Rijssel France.
The 1950s RadioValva Brio BR10 is a superheterodyne receiver (often shortened to superhet) which uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original radio carrier frequency. The system was invented by US engineer Edwin Armstrong in 1918 during World War I. Virtually all modern radio receivers use the superheterodyne principle. At the cost of an extra frequency converter stage, the superheterodyne receiver provides superior selectivity and sensitivity compared with simpler designs.
