The Armstrong Oscillator is identified by the feedback link positioned as a secondary winding on the tuning coil. The feedback mechanism is a coil that couples signal from the output of the amplifier back to the LC resonant circuit with the proper phase for positive feedback. The following Circuit Diagram and Wiring Schematic show Armstrong Oscillator based on the Regenerative Receiver circuit. Read more [...]
