Hi Terry,

I've seen at least one schematic of a TC being used as a transmitter where a tap was made into the bottom few turns of the coil at the base and this was used to drive the antenna (of proper length).

That would be an incredibly inefficient transmitter as most of the power would go to losses in the coil. An antenna "of the proper length" I assume means something approaching a quarter wavelength - pretty long at say 100 kHz!
