Whilst a teletext encoder would be cool, what would you transmit?
THe obvious thing (this being classiccmp) is telesoftware for the BBC
micro :-)
Also, unless it piggy-backed an existing channel, how
would we tune our TV'=
s in to the right frequency? Or would it be possible to place it on the "ed=
ge" of an existing channel, without interferring with the channel itself?
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.
