Treasuretronics BFO

[Melbeta]

Thanks, I agree they were good machines...

too an little special spring iron wire conect in coil reference of bfo's help very much how antena, for put most sensitive, too and indicatior analogic help much due to what magnetite and coil interactuate help trap major the waves, existing so interactions whit all other coils, by total 3 coils
very stable bfo, the bfo not detect little trash very necesary in modern fields
so an large coil in bfo, not detect medium objetives
if you put and special sparks in down coil, these work how white sound indicator of nearby of objects
the bfo was an error the suspension of these production, bfo is good, not toy
bfo for president

I agree. What you said was interesting...

To the BFO circuit to my

[detectoman]

yhl; want in google page; bfo saxon or bfo home clara, this simple and accept all class modifications
put in winds reference coil 330.. ? turns more lees, wire .20 on plastic tube .5 cm
then calculate at turns of the other big coil, in base to this whit wire cal.28, 29, more lees, @ silenced the speaker
reverse the first oscilator transistor bc's, then take your stable bfo
only these is my help

[detectoman]

other thing, coil reference should have iron or ferrite, center nucle adjustable

for operation, see in youtube; bfo's, beat frecuency oscilation or, metal detector bfo, metal detector saxon, etc
