sorry for the long delay, I have built both circuits of this LRL and they work,there is no mistakes there.Originally posted by Saiman View PostI made PCB1_B.RF.OSCILLATOR, circuit I uploaded here.
help me check this circuit.
And how do we know this circuit alive, or can be used
regards

yes,I would like to explain more about this project, I need to check my notes about this LRL.
This is a simple metal detector type BFO connected to some sort of ion locator circuit, it was good to locate the long time ago buried gold or silver objects, but as I remember the problem is the BFOs drift a lot and we need to readjust the locator very often for stability.

L2= 18 cm x 11 cm BFO coil made of 12 or 15 turns,wire 0,25 mm. No Faraday Shield.
PCB2
L1= Big Aluminium Antenna 22 cm x 30 cm(ion detector 1)
L2=Small single turn,copper antenna 8cm x 4cm ,Ion detector 2(this one fixed in the wood box,behind the BFO coil).

the correct value for the C12 is 125 uF 16v, you can check the material list in the first page of the thread.Originally posted by Saiman View PostMorgan hai, hai all.
I have a little problem with the value of capacitor C12.
How Did The real value? 12.5uf? or 2.5uf, or 25uf.
Help me. The real value for c12

I am very interesting to test your BFO LRL.Originally posted by Morgan View PostTO EVERYBODY WHO DECIDE TO CONSTRUCT THE LRL BFO ANTENNAS,SHOULD SEND TO ME PM FOR MORE INFORMATION.
Go comfortable and send me all informations including tuning, You have my email
00000
ps: Maybe it could be drastically improved ....
