I was given a Philips electronic engineering kit as a child; I think it was one of
THESE. What a brilliant present!
I got into domestic wiring first when my dad was rewiring the house, then after someone gave me an old telly to pull apart, I got into electronics.
Fascinating stuff, but I'm not going to do that for a living!
The only reason I ended up in radio is that Marconi were just down the road from here. I interviewed with the Post Office as well, so it could have been telephones.
I've read a little bit about laying out pcbs for RF circuits. That really is one of the Black Arts!
You'd be surprised just how many radio engineers don't get that. We had staff to lay out PCBs, but they were non-technical people who were just joining up the dots. I insisted on laying out my own boards, but it was unpopular with management who had cheaper people to do it, unpopular with the staff whose job I was pinching, and unpopular with other engineers who saw it as menial work and didn't want to be made to do the same.
It's not just board layouts that are a black art, in RF engineering you quickly learn that a MkI finger is often your most useful piece of test equipment. With experience you can learn an immense amount about what's going on in a radio just from looking at what happens when you stick your finger (or more usually a scalpel) into various places. You can't just prod a scope probe into a radio and get any sense, because the capacitance loads the circuit too much.
I recall an unstable transmitter I had once, the instability stopped after it had been warming up for 30 seconds, and it also went away if you put your hand within 6" of the circuit board. That was fun, I was working with components taped to the end of a wooden ruler.
