OK... I take back what I said... It is theoretically possible to transmit a
6MHz BW signal on a channel with a bandwidth of 400kHz, but I still doubt it
would be _practical_. (According to Shannon's law one would need a SNR of
about 90dB)
Given that the bandwidth of a Tesla coil operating at 400kHz is probably a
lot less than 400kHz (because it's a high-Q resonant circuit) I still think
it would be practically impossible.
