Oh, I certainly couldn't trasnmit it on the TV band. The solutions are
either to simply use it as a demonstration of the BBC decoder and feed
the output of the encoder into an RF modulator that is then cabled to the
BBC decoder, or to trasnmit on an amateur band and use a special
receiver. Of course you're not allowed to roadcast on amatuer bands,
rather you have to communicate with a particular other ham, but there's
nothing to stop others listening in, of course.
