Thanks, I used to build these in the long gone days of my youth and Radio
Luxembourg. I also used to build crystal sets in walnut shells as an example
of micro miniaturisation - the only thing was, you needed an aerial about 50
yards long to get a decent signal!! Now you can get the whole ruddy thing
and much more in a wrist watch and people still keep asking me to work on
them.
