Another way do to the test would be to construct the type of receiver that
Tesla himself used to detect the signal generated by a distant Tesla coil.
It consists of a well grounded helical resonator (a fire hydrant works
great) with an elevated capacitance.  The system has to be exactly tuned to
the operating frequency of the Tesla coil.  When properly tuned, you will
find is system produces weak electromagnetic radiation at the operating
frequency.   Use your long-wave receiver to detect the signal, keeping the
receiver off the ground on a folding wooden table.  Ground the receiver, and
use a piece of wire on the external antenna terminal to a point near the
vertical wire about 2 ft. above the top turn of the resonator.

For a description of my receiver see:  "Tesla list" <tesla-at-pupman-dot-com>, Re:
