Hello to all friends
This forum has been quiet and inactive for a long time.I want to start a topic for an idea, making a detector using two oscillators.Please share your thoughts in this regard

Did you make it or is it just an idea?
The oscillators here must be at a frequency of megahertz, one antenna is enough, the balancing between the two oscillators is difficult, you need a precise variable capacitor
