N8VEM project with my son?

One fond memory I have of my father (rest his soul) is his "let's build a radio" project. He was a little disappointed when the local electronics parts store didn't stock UV201As, vario-couplers and book- type-capacitors, but we made do with a 1G4G, hand-wound coils and a traditional variable capacitor. Built on a pine board with an Eby surface-mount socket and run from a dry cell filament supply and a 45 volt "B" battery. Relevance to modern technology, it seems to me, isn't important. Plenty of dads show their sons (and daughters) how to work on 60's muscle cars. But do something together, even if it's shooting rats at the town dump. Whatever you do, you won't regret it and your kid will remember it fondly, however it turns out. --Chuck
