"PER FREQUENCY"Then you should know better. Not going to personalize this via email. Nor am I trying to flame anyone. There's enough evidence to show the correct technology.
Question: what do you mean by "barn door"? That it's "wide enough" to let anything in? If you've looked at the schematic the front end is as it has always been since Armstrong invented FM. A high Q RF tuner, second Rf stage, local oscillator, IF stages.
Superregen won't separate two equidistant FM stations from being received at the same time at the same frequency. And oddly enough, your statement about "turning up the wick" reinforces what I said about using an adjustable attenuator in the line of the antenna. The reason your regen does that is because now you've increased the sensitivity.
And now we seem to have come full circle.
