Hi,

You missed a resistor from the schematic. You have 11 resistors including the antena but in your schematic you have only 10 resistors.

Can you check the schematic?

Thanks.

Mea culpa, there’s a standard 1/4W 1Megohm and one SMD 10 Megohm resistors in series for the input ( for a total of 11M, but that’s no too important) so I have drawn only a single 10M resistor in the schematics…

@LEDchaser Thanks. I asked to be sure that I'm not going to build a wrong schematic. Thanks again.

In my opinion it’s not worth to build your own device, better buy one for $ 2.11 on eBay…

See the video for the ‘’home made detector’’ I have allready tested…
