Thid said Esteban to me (or I'm Esteban) :

The detector has an audio gen. tone with speaker, first models with transistorized flip-flop as tone gen.

Why BFO? In early times this was common detectors. So, later we use IB, off-resonance and primary experiment with PI. And other kinds no-based on regular MD.


Grrrr!!!! But the truth.
