The second schematic on this link, the “common base” looking circuit, I first saw around 1975 in some collection of ‘simple transistor circuits’

Jara, my computer freezes when I try to open the link. Maybe the "no power" radio could operate on a small solar cell or a thermo pile. The Crystal Set Society

Hi all, here you can see a few schematics receivers without battery "as inspiration for regen without battery".

Years ago I built one using a longwire antenna, circuit tuned to strongest station and diode rectifiers to trickle-charge a NiCd which powered the Ge regen. It

... I use it with my old "DX394 Radioshack". It work very well. Quadrature demodulator you can use also for FM, for instance FM CB radio (27MHz) in EU. ISB is

Thanks, Hue and Michael. I found the "hookah powered" schematic online. I may play with that bias resistor and the RFC as well. I figured the leakage bias

That's the same very basic circuit in the 1961 Popular Science magazine "Hookah Powered Radio" article, powered by a candle thermocouple, except that it used a

Also spotted a Hammarlund HQ150, I was lucky enough to pick one of those up, they are few and far between here in the UK, nice receiver, the Q multiplier works
