Ross, way to go! 28" issn't too bad, better than I have ever been able to
get. How much did you drop the Fr0 by with the addition of the toroid? Did
you tune to match with the tank C or L? Changing tank impedance may have
had more to do with it than anything else?
I have put coiling (tube, of course!) away for the time being, as I have
been focusing on my Pyrotechnics interests (not Tube Pyro!), but will
probibly get back to some old projects this summer.
