And yes the radio works
with the ground and antenna connections reversed. The diode is a piece
of galena.

Does "it works exactly the same"?

yes

Your radio is not the simplest. There is the LC. The capacitor has the two
plates so on the both the voltage is doubled. No matter which one is fed to
the headphones.

Could you make the super simplest radio: "Because I have a long (150 foot)
antenna, a good ground, and a strong station (50,000 watts) less than 20
miles away, my radio receives enough power to light a low current LED. The
LED is a 'high brighness' type (which also means that it will light dimly
with a very small amount of current). I connect it instead of diode in the
radio, and it glows as the radio operates, getting brighter as the sound
gets louder. "

The super simplest radio should consist of an antenna, LED and ground.

Can we reverse the LED?
