I have a
1950s Bush TV22 in my den which I sometimes fire up so that I can watch TV
in wonderful 405-line monochrome, though I don't try to pretend that it's
better than a modern colour TV!


You manage to pick up an old 405 line TX then?.

And standards converter;?...


I built myself a digital line-store standards converter back in the 1980s
after the 405-line transmitter network was switched off. This feeds a
modulator based around a couple of MC1496 multiplier chips (one each for
vision and sound) which operates on Ch1 (45MHz Vision, 41.5MHz sound).

And have you got a "H" type or "X" type aerial on your chimney;?...
