This circuit has a gain of 34 dB and a good power to be used as an audio booster in cars. The configuration was found in the 1982 SGS linear integrated circuit manual.
This configuration makes use of an integrated circuit of the time having been found in a 1976 NASA...
The signal itself captured by the (long) antenna serves to feed this simple experimental circuit....
From different input voltages V, it is possible to reduce the voltage to several fixed values...
