    Itsu:
   So, are you saying that without the PWM, our home made Kacher/Tesla coil will not be able to lock onto the specific frequency of the Kacher's secondary coil?  Is a PWM controller like the one I just linked to needed then, or not?

Ok Void I appreciate your help , but I asked IF and HOW katcher then self-adjust to that frequency so I can be sure it resonate at correct frequency for  secondary (plus antenna). Anyone with katcher and good scope can confirm , but I have only old analog scope and measuring frequency is not so easy. I believe information about HOW to adjust katcher to resonate at precise Tesla frequency for coil is the most important one.Especially if it can do that automatically (can?) .
Or in other words : can we adjust katcher frequency and how ?

Hi Forest. The kacher driver will automatically adjust to the tesla coil's secondary resonance frequency.

The only adjustment you really need to make on the kacher circuit is to adjust the base bias for
the transistor using a variable potentiometer for the base resistor. This adjustment is not for
frequency however, it is to adjust the kacher for the best waveform shape on the collector of the transistor.
You can also make adjustments to the primary winding on the tesla coil to try to improve the kacher waveform.

Nick,

no, most kachers are running without a PWM, look at Ruslans diagram, it runs fine with a single transistor/MOSFET driving the kacher.
So a PWM is not needed but could be used.

Have a look at this circuit http://overunity.com/12736/kapanadze-cousin-dally-free-energy/12180/#.VvmfY3oa7vx
Just ajust coil f and output amplitude.

@NickZ

Would it help if I wrote that the natural oscillation of a Katcher is a RF carrier, which is amplitude modulated by a LF waveform of the PWM controller ?

You can hear the LF but not the RF.
