Simple Homebrew SSB/CW Transceiver Part 4a - Updated Product Detector

Quick video of the updated product detector. Again using the dual J310 configuration. Fine tuned using LTSpice. Might change track now and do some software engineering and develop a variable AF LPF filter on the Teensy. We can then double back and look at pre-selector filtering before looking at transmit. I also need to ensure the various stages are impedance matched for maximum power transfer. No rush!
