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

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?

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.

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

Default 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.

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

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

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

1hz to 1mhz
