This amplifier step for small signals can use any general-purpose transistor like the BC548. The circuit can be powered by voltages from 6 to 12 V.
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....
