a few years back. Maybe American Masters ? That photo with the first "portable" superhet beach radio was in it. May be available at the PBS video outlet; it was a nicely done bio of an irascible but honest prodigy. I think this article captures the sense of Armstrong's actually grokking FM, where the equations led to no sense of how you could Do that, practically.

No question what kind of bastard he was dealing with in 'General' David Sarnoff - perhaps the epitome of vanity and a prequel to The Billy. Ditto Lee de Forest: the vanity without the talent to even understand how his 'audion' worked, nor the guts to thank Armstrong for explaining it! Creep.

I recall seeing a film of a This Is Your Life smarmy tribute to de Forest... prolly in the '50s from appearances of the players. It was exactly like a M/Sloth "innovation" press conference; almost nothing said about deF was accurate.. but he ate it all up.

My intro to big science electronics was via my boss and I (on a weekend) assembling a super-regen FM receiver with a simple slope-detector ... out of junk lab parts (and a box of Really old resistors from his junk box!).

Bloody thing worked.. just like A. said it should. Amazing (to me then) to take circuits right out of textbooks and see them work! Getting local KPFA after switching it on - goosebumps. I began to think there might be something long-term to this 'lectronics stuff (but I was wrong again).

Seems to have been lots of techno-rotters.. you can drive by the site of the first actual Tee Vee - Philo Farnsworth's lab in SF (ironically now housing a TV ads production company!) He too was screwed out of his clearly 'prior art' - by those famous 'Market Forces' which measure our hallowed succession of truly nasty bastards in expensive suits.
