The divisional harmonics and the heterodyned output is smaller. ;)

Did some tests.

My friend lent me one of his oscilloscopes yesterday. A huge improvement over my of old tektronix tube type O-scope that is so far out of calibration that locking on to a signal is a rare thing.

Took a coil I had lying around (17" circumference, 39 loops of 28 gauge magnetic wire for a length of 2082 inches) and wrapped a few loops (40 or so) of 22 gauge hookup wire. I drove it with a simple 3904 npn transistor with 5 volt supply and my frequency generator.

It's nothing fancy, not even close. I did it because I personally had never thought about pushing a current down a wire with a coil that was wrapped around it's length. So I did the test and it does work, as you all know. I got a small voltage on the inner coil.

I had calculated that physical length of the wire in the coil would be at resonance at 5.38MHz.
(Speed of light in wire = c * 95%
divided by
(Wave length = 2082 inches
equals
(5,385,847.6 Hz

I can' reach that freq so I will have to do something different. (bigger coil!)

I am seeing something on top of my signal. I believe it is the 39 loops because they are very regular. For every pulse I put in I get 39 pulses evenly distributed along the length of the wire.

I would send you some pictures but I can't get them off of my phone and I don't have a regular camera. I'll see what I can do.

Hi all.

After thinking a lot about how a toroid works I have decided that a Phased Locked Loop would probably not work as I wish it would. The main problem is feed back. If there were only one signal traveling around the toroid there wouldn't be a problem. But there are always two separate currents, one for the powering up of the coil and one for powering down the coil. One signal in and two separate current flows from it.

Here are some pictures.

LOL,  you're killing me man.  :D

Nice work though.  Keep up the good work!!
