Lrl from Italy

dear franco
If we put instead of 8 mhz 9 or 10 mhz Are performance differs

Thank you dear franco and mustefa

Hi brs,

The gain of the sensor stage also depends on C13 / C14 and then increasing the frequency (from 8 to 10Mhz) also slightly increases the gain. However during calibration we determine the appropriate value for C13 / C14 for maximum amplification can be useful for that frequency. Changing the quartz (and therefore the frequency) after the calibration certainly increases a little the gain. The situation is different if you've noticed a different sensitivity to a given metal.

Best Regards

Thank you dear franco

Here I attached a new PCB of the 8MHz - Quartz LRL Sensor Stage + Power Stage with Low Battery Indicator + Display Stage (3 LEDs), and its schematic. Hope it helps you my friends.

hi dream man


can you give me the part +/- battery?.


I have to make a switch?

thank you very much

help

hi all friends


i have built dream man pcb I use a bc190c place bc183c is that they have the same location.

i have not electricity in the pcb no power

help me soory for the little english

thank you

Pigeon have you fixed the problem? What pcb have you made?

Franco tell me your opinion about MFD, do you think that your lrl in combination with MFD transmitter will give better results? If I'm not wrong your lrl catches the phenomenom and the MFD transmitter should amplify the phenomenom (actually it amplifies the metal's frequency which i think is very close to the phenomenom). Also i want to mention that by my last tests the lrl catches the frequencies emitted by radio/tv antenna and phone (gsm/hspa/lte) antenna but it doesn't catch frequencies emitted by police walkie talkie antennas (i don't know at which frequencies any of this antennas work).
Best regards.

I don't think that MFD may help with lrl because the frequencies are very different but I have not done any testing, maybe a harmonic of the MFD can happen in the range of LRL.

Dear Franco, MFD frequencies for gold as listed on forums an on MFD manuals are 5khz for gold and 8.7khz for silver. I think that in earlier posts you said that your lrl works around this frequencies. Thank you.

[FrancoItaly]

My lrl basically is a receiver tuned about 100 - 150 Mhz which detects anomalies in this range, then very far from 5 -7 Khz.

Several years ago I made tests with MCD and dowser and found that this system is too influenced by the human mind and therefore unreliable, at least in my case.

[Napsterce]

Yes that is coreect but i will try to use the MFD transmitter with your lrl. Like i said, i hope that it will amplify the phenomenom field so it would be easier to be catched by your lrl. The MFD you have built was with powered L rods? By what schematic you have built the MFD? Thank you.
