All, and Chuck Curran,

Yesterday I made an error in my writing.

The original Fo of MTC with the 12 X 48 inch toroid was 87 kHz not 78 
kHz.  That much larger toroid added _does_ make much more than a 3 
kHz difference, it is 15 kHz as stated.

Sorry for any technical confusion this error may have caused.
