Special thanks to W2aew!!!
The crystal oscillator and balanced modulator circuits are based on videos from W2aew. His original schematic shown in this video, has been modified for this project. I've added RF chokes on the supply, a two stage audio amp, a tuned transformer on the oscillator output, and a two stage linear RF amp after the Gilbert cell circuit.
