Hi Gang

Many years ago I tried to offer a British NLJD, if I remember correctly 
it was called the Diviner, that met with the same lack of success my 
many other NLJDs met.  It made NO DIFFERENCE whether they were FCC type 
accepted, and some were, or not.  The intelligence community simply was 
not going to by ANYTHING from me.  You may read my comments on my NLJDs 
at http://www.martykaiser.com/nostal~1.htm  That aside, I continued 
experiments on finding non-linear junctions.  Here in Baltimore we have 
two megawatt TV stations, one at roughly 200 MHz and the other at 
roughly 212 MHz.  I thought, why should I build an illuminator when 
there were already two perfectly good ones in town.  I put a tuned loop 
on the end of a stick, tuned my receiver to the sum of the two signals 
(412 MHz) and found all the non-linear junctions in my home and plant I 
could ever want.  Listen for the raster buzz.  The difference of the 
two signals (12 MHz) proved useful for locating wires.  Give it a try.
