Found in old documentation, this receiver for the mid-wave range uses transistors from the era. In fact, modern general-purpose equivalents can be used.
The width of the pulses produced by the oscillator in the figure is determined by the value of R1,...
We found this approximately 1.5 kHz oscillator in Texas Instruments technical documentation. The...
This circuit was suggested by old French documentation, but it can be used as a shield, in which...
