Could you make the super simplest radio: "Because I have a long (150

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?

Very innovative

What indicates the DC meter close to transmitter between the antenna and
ground?
