I don't think
Before some years a friend gave me one oBMD1 for one week.
I went at some ancient places for test.
No one beep

This project has been frozen for 6 years. The device is working in general, but I could not handle its settings. Can anyone tell me what frequency does the receiver and the induction oscillator work?

Sorry i am busy.
I started to write and did let it...
Today morning i updated the schematic with parts but only for IR section, beeper and preamplifier. All the other are the same from Andy Flind magnetic field detector. So maybe tomorrow i will check it again and will post it here....

There is no induction oscillator in crypton OBMD. It is purely a passive LRL...

the infrared sensor controls the power supply of the IC7. IC7 acts as an excitation generator and is inductively mixed with the signal received by the receiving coil.

I think it's the mixing point between IR oscillator excitement and receiver ?

dragomir I had no answer ???

The IR manages a transistor that turns on and off the power supply of IC7. The IR does not participate in any process. When the device box opens, it blocks the operation of the IC7 and the excitation generator stops working. This is probably done so that the principle of operation can not be traced when the device opens.

My LRL does not work because I do not know how to set it up. I remember detecting a 3-meter monitor, but it works only as a receiver without the excitation generator. now, if I remain free, I can experiment with it
