Very nice work, Brian ! You are on the right track, IMHO.
However, you have a couple of things to think about and to test.
There is a ground, probably. Most function generators and other bench equipment like oscilloscopes will have their chassis ground wired to the ground plug of the 3-wire line cord (the green wire). Even the neutral wire (the white one) can wind up providing a ground to earth in some cases. This means, at the relatively high frequencies you are dealing with, you are surrounded by the system ground in your house wiring and the Earth. This, by the way, is how Tesla coil enthusiasts manage to light up 25 watt incandescent bulbs with only one wire connected to anything. Your handheld meter won't show any power coming from the function generator thru the one wire -- it's optimized for a much lower AC frequency, but there are ways to show that there is, using your oscilloscope.
You might be surprised on how much your stray wiring "layout" will affect things, even at 5 MHz. May I suggest the following:
First, before changing anything, try to figure out some way to isolate (just for this one test) your function generator from your housewiring ground. If you have a computer UPS, you can try running the FG with it (unplugged from the line of course!) for a few minutes. See if you are still able to tune in and light the LEDs. Second, scope the signal at the big red LED -- if your FG ground is still isolated you should be able to do this and still tune in the power. I'd like to see the waveform here.
If you look at my YT channel you can find a couple of videos that are relevant to your work.
(Nice little coils by the way. I wonder why you used syringes, rather than, say, toilet paper rolls or medicine bottles.)

You have impressed the master [TK],This is not easy!!

Are quartz crystal resonators or oscillators used in the TPU or any other OU device. they are interesting .
