Max,
i tried that method (still working on it), and yes, i noticed the Grenade terminals are closed (shorted).
The transcription from Vasik (pp.pdf) mentions why Stalker does this as it says:
1. short coil and use current sensor (coil will be in ½ wave mode)
So Stalker says that by shorting the Grenade it will be forced into half wave resonance.
Itsu,
To be candid I just heard that Stalker said that by closing the terminals of grenade coil, it will be in ½wave mode .In your case your are looking for a frequency of res. Which doubles your previous resonance. I don't think that is possible.
Now looking at his, he only got 0.91MHZ. that I believe is a far cry from his ¼ wave res. howbeit ½wave res.
I think there are more to these.

I tried that methode and used my current probe to look for current peaks within my Grenade.
The results were that i have a first small peak at 1.341MHz (range 1.191 - 1.631MHz) and a second bigger peak at 5.691MHz (range 5.521 - 5.791MHz).
It also showed the increasing current on the 1st peak when touching with my hand and a decreasing current in the 2nd peak when touching.
That's correct if both responded in that manners when touched with your hand.

The next steps (9 and on) in the PP.pdf are not so obvious as the FFT (or SA) does not show clear peaks when using sub-harmonics in the 119 - 163kHz range, so i am looking into that now.
IMHO, why not use wound current sensor as in video.

But my current peaks are nowhere near (or double) the quarter wave resonance peak (1.879MHz) i found earlier using several methodes.
I would expect the Grenade when in half wave resonance to show double the freqeuncy (so 3.758MHz) as when in quarter wave resonance (1.879MHz), but it does not.
Itsu
Even his could not get to ¼wave res. Talk less of ½wave res.
Since 5.691MHZ is your peak of 3rd res. I think you get a diy current sensor and sweep b/w your 119KHZ and 163KHZ while doing that, you might hit. Frequency where 5.6MHZ is outstanding amongst others.
