Hi Esteban,
counting 1Hz or 2Hz or 3Hz over 300KHz is about the same thing.
Changes nothing in practice.
1Hz -> 1/300000 = 3.33333333333.... * 10^-6 (3 ppm)
2Hz -> 2/300000 = 6.66666666666.... * 10^-6 (6 ppm)
Even at 10Hz over 300KHz is 30ppm. Do you say that your circuit can find coins from meters (or hundred meters ?) using 3ppm or 30ppm frequency variarion detection ?
In real BFO or OFF-RESONANCE there are KHz variations on the same frequency. More than 1000 times of yours.
A 3ppm (or 30ppm) variation could be due to as many factors that you'll never discover from where it arrives.
E.g. a capacitor could heat 0.1 °C more and you'll got 30ppm frequency shift.
Quartz crystals have often a span of +/- 30ppm and even more.
Do you use cesium in your timebase ?
You'll never detect a 3ppm variation from a remote object meters away(supposing that this variation exist for real) with these garage made toys.
BTW I never bought one of these things you call LRL ...see some used by friends... other LRLs ever not seen cause nobody found anything with that, so they reselled to other naive THs.
I think that all this stuff don't work, can't work.
Best regards,
Max

Much like a radio... have to tune with sweep generator... bell-filters and everything.
