Mark,
Yes, but is not coil  harmonic content quite rich? Were this not the case,
Dan's ham experiment would not have yielded such results. Of course, Dan did
not mention the band(s) on which the experiment was performed. But still....

All,

What Dan fails to mention is that the typical operating frequencies of a TC,
60-500kHz, are way below any amateur radio band.  Primarily these frequecies
are only used for radionavigation.  With the short duration run times we
normally do should not cause anyone that locally happens to be using that
frequency a problem.
