This thread seems like nobody has been on it for quite some time, but I was thinking that a loop antenna may help you with your power to transistor problem. Check out this youtube vid. :)

Hi everybody!

I found this AM radio schematic and I think it works fine. Don't need a battery, it's powered from antenna energy.

Try to make it and let me know how it works. It uses an old germanium russians transistors, but you can try european or japanese equivalents.

You also can try another schematic from this link: ... ivers.html
