Regenerative Circuit

[Electro132]

Hi,

Needing some help with both these circuits. (See attached) I have applied a 3v lithium ion batt and could not get the ends to work powering a simple green LED. Not sure why. However, when i checked on my laptop oscilloscope i am picking up on electrical signals.

Any help given is appreciated.

Thanks

Regenerative circuit? Not. These are two "crystal set" AM radios with two stages of audio amplification. And where do you see any "3v lithium ion batt" or "simple green LED" anywhere?
