Hi,
A better test would be to run the secondary at Fo from a signal 
generator in say an open field and use a LF radio receiver.  Just 
walk back and find out how far you get ;-)
Would it be useful to actually do this test??  I have a fairly nice 
(all digital, so you know it's good ;-)) receiver that has a 144kHz 
to 288kHz band.  I can probably get a ~200kHz coil going 
somewhere.  Perhaps the TCT could be a signal generator unless 
somebody's boat has a 120VAC invertor on it (Gerry??)  Then I could 
us the HP signal generator.  I just bought a super nice UPS 
too...  Perhaps the DRSSTC or DF-DRSSTC could run off the old UPS...
It could be run in the back yard in suburbia too...  One person out 
there with the receiver and GMRS radio...
Maybe not real science, but it would put a stick in the sand...
Cheers,
        Terry
