Since James pointed out my Q measurements were at different frequencies, I
did yet again. This time:

No core:
L sec = 10H, C= <10pf, Fres=8.15Khz, Fh=8.31, Fl=7.9, BW=.4Khz so Q= 8/.4 = 20

Core in: (which reduced amplitude 3db after retuning)
L sec= 50H, C= <10pf, Fres=3.5hz, Fh=4.0Khz, Fl=3.9Khz, BW=.4Khz, so Q=4/.4
= 10

Increasing the frequency does help, which is fine if your using it as the
main resonator, but dissapoint if, as I, you wish to use it in place of an
Neon, MOT or OBIT.
