frequency for the cavity

[ma330]

hi to all
I want to know is the frequency for the cavity in LRLS
tnx

As lrl Do you mean the mfd (generator) or all the type of lrls??

mfd lrls
????????????

Hi Geo , for cavity with MFD you which frequency use, or please write All use frequency for cavity.



Regards.

The exactly frequency is depended by the user.
It must be near to 10.050 Hz

Ok Geo ,very thanks I will try this freq. (as Hertz not Kilohertz),
and what it means ''The exactly frequency is depended by the user ''.

Hi Humhum.
I mean that you must play a little with few hertz and to see when you locate the cavity better( better center). You can make tests from 10030 to 10070 Hz at steps of 1 or 2 Hz.

Good luck

What if your cavity resonate at 57Hz?

No responce from lrods at this frequency

Hi WM6 ,Do you try this 57Hz for cavity with Lrods , and how is results?

Ok Geo , With my Lrods I will try test for cavity , with 10Hz +,- steps of 1 or 2 Hz.

Best Regards.

It is not problem to detect known cavities for me. Even without L-rods.

Can you tell us your way without l-rods?????
But maybe you have special detectors only for known cavities!!!!!!

Hi WM6 , Can you send photos from your L-Rods .

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

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
