frequency for the cavity

[Geo]

My frequency about 6K5,but I only search Long-buried copper,Can search fron 1 km away. VR1000 Circuit

Do you know who is the output voltage???

Hello,Geo
Above 555 constitute a step-up circuit, below 555, the control frequency output

[gwlwudi]

I have done several tests, this circuit can be used, but there will be intermittent signal, I still do not understand how is it

[Freelander]

witch device?

Hi all,

Pls can you specify witch device do you use, that you can input the frequency value directly?

(Because I will build a Carl'MFD with knob connected to different capacitors values to change Hz.) I'm asking if there is more better solution.

[Geo]

You may buy a DDS generator from ebay and connect it to a power amplifier.
Good and cheap solution

[Freelander]

Thanks Geo for answer,

You mean that is better device than the BasicMFD, I already start building this one and this make me hesitant

I mean better use the DDS instead of the ICL8038 frequency generator to build developed MFD?

DDS behind plus a power amplifier is the most simple and easy to use design

[Freelander]

Ok, thank you friend, I will start my request in new post, to respect the sens of this topic.

Vacuum cavities are due to the accumulation of ions and holes have different frequencies in different situations.

1hz to 1mhz

Yes my friend you have reason here the frequence to void is 300Hz to 1.8Mhz ..this with my LRL it's depend of cavity and the carbone Good knowledge

thanks my dear

If you are talking about sealed caves then you should check for CO2 and N2. Most sealed caves have bad air which is high levels of carbon dioxide and Nitrogen. If most of your cave have stalactites and stalagmites then you need to scan for CaCO3.

Research air in sealed caves or bad cave air. If you need the frequencies for the above I would need your location.

Thanks Tim good interference

give us a general rule of calculated frequency

suppose that place is the Greek

[Tim Williams]

Location does not matter. If you want to try a test give me your country and city. I will calculate the frequency for CO2. In the USA they use co2 to carbonate soft drinks. If they do there you can take a liter bottle 1/4 full with top on tight and shake it to release gas. That will be the target. Ring theory is used for calculation and is proprietary.

Go to my site and download the EFNMR program. I will post the EFNMR frequency at 50000ut as reference. You can put it in the program and all can test if the want. The program will calculate the frequency. It's free.
