2- Diseño de Tres Radios con Diodo de Germanio con Bobina REPANCO DRR2

Design of three different radio circuits with germanium-tipped diodes, using the REPANCO DRR2 coil, a "Dual Range coil with high gain and reaction." Three different and well-detailed designs. Graphic instructions for building a replica of this coil model. NOTE: An error has been found in the schematics of these three circuits: terminal 5 of the REPANCO DRR2 coil should be connected to ground, and terminal 6 should be connected to the antenna circuit.
