That's odd. Your kacher driver seems to be behaving quite differently from mine.
I have a fair bit longer secondary wire than you and I am getting a higher operating
frequency. Maybe a difference in the kacher driver circuit itself. I am using the common
kacher circuit arrangement with two base resistors acting as a voltage divider to set the
bias point on the base. Bottom of the secondary goes to the base. Is that what you are using?
Which transistor are you using? I'm using the 2SC5200.
All the best...

I'm using the Fairchild FJL4315OTU. I have a 10K pot and 1k5 divider and 5V zener pair with common mode input choke. Bottom of secondary goes to base as with yours. I think the coil turn spacing will make the main difference between our setups.

Hi Hoppy. Ok, maybe something along that line.

 Here is an explanation of  coils by by Robotustra of Ruslan granade coil..

Hi

Simplest method for measuring shortening coefficient cable and cable wave impendance !! 
Instead of sensitive RF-milivolt meter you can use oscilloscope. RF-signal generator unchangeable.

Acca,  thanks for this very nice explaination by Robotustra.

Together with the video links provided by Enjoykin earlier about Akula explaining these steps it must be a piece of cake....


However, the translated (in English) subtitles on those Akula video do hardly make sense, so are useless.
So still we (non Russians) have not really a clue what is being explained in those video's


Probably because of this i was not able to replicate the instructions from Akula to determine the "ground resonance frequency"
of MY local ground. 

(Magpwr, there you have the meaning of "land frequency" you mentioned earlier, not the Mains frequency in a country, but a poor translation
into English of the "ground (earth) resonance frequency").

Using his initial methode to hook up my FG and scope probe to 1 side of a coil leaving the other side open (having the grounded FG and scope
ground leads connected together) shows an almost flat frequency response over a 1KHz to 10MHz range.
No peaks in amplitude.

Then when grounding the other end of the coil has almost no influence on this flat frequency range, some dips, but no peaks.

So i doubt this is a usefull procedure, and/or my ground is not good (enough).
