The push - pull was delivering 24V @ 4 A at this resonance (18.78KHz), so enough juice to fry this 10W resistor.

You do not need to deliver such power just to find resonant points. Limiting to 100mA and 12V on the mosfets would be enough.

Void,   be sure to use a big resistor, my 10 Ohm / 10W resistor started smoking in a few seconds.
The screenshot is from across this resistor  which was attached (only) to the grenade leads.

24V 4 A you so seriously?
"Attach 10 Ohm resistor to the grenade output coil and use inductor with  (generator) i.e., the function generator?
- there is not much voltage generated on the output"
T-1000 uses (shorthand) Hmm.
wonder sometimes are translations (from Russian into English and Polish) :DD
I do not understand current without voltage (read the rms)?

Thanks Itsu. I am testing with my signal generator driving a MOSFET, and I am limiting the duty cycle, 
so I am running the test at quite a bit less power.

Hi Tomtech. I think you just need to look for a frequency in the range of say 10 kHz to 40 kHz or so where there
will be maximum current through the 10 ohm resistor. I think you can test it like I have shown in the
attached schematic diagram. You can just use a signal generator to drive the gate of a MOSFET, or you can
use your PWM generator with ferrite core with the secondary winding connected to the 'inductor' winding
without the series capacitor. (Sorry for the messy diagram )

I think it will be a bit higher than that ! more in around the mhz region I would of thought, your multiplying the rf up in f don't forget.
