"Why hasn't anyone done even a breadboard for a simple inductively tuned AM radio?
Not a bit of digital hash, no PLL issues, etc."

 There's something about the words "simple","breadboard", "ultralight" and "AM Radio" that are challenging to put together. The natural evolution of radio has been from simple but low performance to complicated but high performance. Superhet designs are the cream of the analog crop but are pretty challenging to breadboard due to their parts count and complexity. Trying to breadboard one that qualifies as an ultralight? Good luck! Crystal radios, trf radios, regen radios and superheterodyne circuits are all over the internet. Home built SDRs are coming on strong. I've built a Softrock Ensemble II SDR the size of a cigarette pack that will put any good receiver to the test (but is very tied to a PC of some sort). Heat up the old iron and let us know how things are going. If nothing else you will have a mad appreciation for the brilliant minds that came up with the "classic" designs!
