We had found this circuit in a January 1961 Radio Electronics Magazine. Using it is possible to take measures from the gain of transistor with a common a multimeter.
This simple MW radio was found in a 1975 publication, but it can be mounted with BC548...
This circuit is basically the same as the previous configuration (CB15616E) with a power stage with...
This experimental receiver works with alternative sources of energy or a single cell of any type....
