Apologies to those who know about this stuff, if this is a stupid
question. Seeing the electronics thread reminded me of some of my
mis-spent youth. I never knew enough about electronics to design
anything, but I could usually get something like an amp or a tape
recorder from the tip, and fix it. That was about my limit. I used to
enjoy making crystal radios from some of the bits I'd have lying around,
but no matter what I used, I only ever seemed to be able to pick up what
seemed to be radio 4. If you were to build one nowadays, would there be
any suitable non-digital station left to pick up?

Funny you should mention this...
A couple of weeks ago, I stayed over at my parents, and in the bookshelf
was my old Ladybird book on making a radio, which takes you through the
stages of making the receiver and then adding an amplifier to it.
If you can still buy OC71's, it would still work today. ;-)

I have the Ladybird book, too. The illustrations are just beautiful.
Without that, I'm not sure that I would even have tried to make one.
For years after, everything I made was built on a piece of board with
brass screws, just like the Ladybird radio. It added an amusing and
personal touch to everything.
