Max, you don't understand my intention. I post the pic of presse because is the unique pic of this model with the controls we can see more easyli.

Sorry, Max, yes, strongly I say you that a stable BFO in conjunction with other circuits make operable BFO at regular distance. If is martian for you, for me is normal. I learn other things by other and I know what I say.

Do you think for real you can read a 3ppm or 30ppm variation on an homemade/garagemade BFO ?

1Hz or 10Hz over 300Khz ???

Your memory falls. I explain very well you that non audible minielevation in sound before mix of 2 freqs. is the matter. You insist in your prejudices since your personal point of view and don't leave to explain, include against J_P and others. Here a post on another thread:


Is true if you expect in a BFO, for example, hear 100 Hz, 500 Hz or 1 kHz, so this is the difference when detection occurs. But with another additional circuit before occurs this "great" variation you can hear in amp stage a type of "breeze" and this isn't an audible tone. So, this minielevation in sound level before occurs real audible tone is the theme. Various times I wrote about it.

And yes, all are proofs. I don't see other person like me who can post pics with different electronic LRL managed by different persons since the 70's. If you're intelligent, also you'll see the progress through the time: first search head with cable attached at box and later integrated in an only body. What reason for to lie since more 30 years?

I like old BFOs... but what's "a good BFO" for you ?

You know: stable, all we know that, IN GENERAL, BFOs are not very sensitive.

Hi Esteban,
"What for? If you're VERY SURE THAT IT DOESN'T WORK, so, why do you want it? "

I'm sure it doesn't work locating metals from far away. That's my opinion.

But I think would be a good thing if you post it anyway... many other peoples here wanna se one of your design, to test it.

So why don't ?

Best regards,
Max
