RE: SSTC - experiments

Dave,
One thing *you* are forgetting is that at 200-300kHz, a 4" electrode rod
placed above the top load is an
extremely inefficient radiator. Its probably negligibly more than what
a SSTC radiates by itself. To get
efficient transmission of RF power, you need an efficient antenna. A
1/2 dipole antenna would have to be
2340 feet for 200kHz. There are other harmonics, but these are buried
quite deeply.
Also, SSTCs radiate quite a bit of RF in general. When I audio
modulated my coils, I can pick up the transmissions
on my friends HAM set-up (with his huge tower antennas) almost 10 miles
away (flat terrain, no hills, mountains, etc...)
