Concerning the interferrence on the kacher output signal (not a nice sine wave), i think it could (also) be caused by the burst of pulses.

Like ringing a bell, but keep on tapping the bell in an irregular manner so each tap causes a new ringing so the
ringings start to interfere (in phase adding, 180° out of phase stopping and anything in between) with each other, until stop tapping,
then the strongest resonance remains.

Just a tought,    Itsu

Itsu,
This only would appear when the feedback from the secundairy is exciting the mosfet driver in a bad way.
Perhaps you need to clean the signal a bit up.
Scoping your DRAIN》》SOURCE would show if its caused by inproper switching.

I did not see a messed up ringing nor using FET' s in single mode.

Stalker!

if it was a car engine would you fire the sparking plug wile starting to inject fuel into the engine ?
So why does Stalker suggest you do ? mind boggling.

   And, there may be a lot more interference once the grenade is connected up, also. As the earth ground on the Kacher emitter is also connected to the grenade. So, there is where the diode comes in on the emitter. I would suppose.
   Are you using some type of earth ground on the Kacher transistor emitter yet? Did you place the ferrite rod before the antenna?   What happens if you reduce the 4 bursts or so, to just one or two bursts? Does the signal look better then? Just some thoughts.

Thanks guys,

below screenshot 1 shows the push pull drive signals in yellow and blue (so not directly the TL494 signals, but the delayed sigs
from behind the TC4093 going to the push pull MOSFETs (not installed)).

The purple and green traces are the Kacher MOSFET gate and drain signals (12V on the drain from a battery).

The second screenshot shows again a zoomed in display of the Kacher MOSFET gate and drain signals.


Nick, 

no ground used at the moment, no ferrite rod (choke), no antenna.
Its beautiful weather here, so enjoying primarily that and playing around on the bench only some hours in the evening.


Regards Itsu
