The fog of ingrained stereotypes lives on long after the Soviet
Information Bureau published "Falsifiers of History." Stalin
personally edited the book, rewriting entire chapters by hand (how
well we experience this here, daily). The book claimed, for instance,
that American bankers and industrialists (are you rich enough?)
provided capital for the growth of German war industries.

I prefer Wiki:
"The voltmeter in the same radio reads 125 millivolts. Since watts (the
measure of how much power we have) is the voltage multiplied by the amperes,
we have 0.000175 times 0.125, or 0.0000218 watts, or about 22 microwatts.
The station is putting out 50 killowatts, and we are receiving one ten
billionth of that power, yet we can hear it across the room."

Could you help? The simplest radio:
" Tape the other diode wire to a cold water faucet. This makes a good
connection to the ground, and is thus called a 'ground' connection.

Hold the remaining free bare wire of the earphone in your hand. This
makes your body into the antenna for the radio. Put the earphone in your
ear. If you are close to a strong AM radio station, you will be able to hear
that station faintly in the earphone. You may hear more than one station at
once. "

The diode has the two ends. Which one should be tapped to a cold water
faucet?

well, of course, once you put a diode in the circuit you are forcing
flow in only one direction. but try this, turn the diode around so it
only allows electron flow FROM the ground... and you will still hear
the station. so now how do electrons flowing from the remote antenna
through the air get to ground through your diode??

:) Nicely put.

But the moron either won't get it or will deny it anyway. Matters little.

But we all know that there are positrons. So maybe he's right after all.

After a few milliseconds contemplation I've decided to go with not right.

of course he's not right, but its fun to see him try to fit his 'new'
square theory into a nice round hole.

yes, its the same in both directions.

My only question is why does my crystal radio work without a ground
connection? Yes the radio does work better with a ground but that does
not negate the fact it works without a ground. And yes the radio works
with the ground and antenna connections reversed. The diode is a piece
of galena.

yes, the diode may be mounted in either direction and it works exactly
the same.

Apparently, You have never heard of Capacitive Coupling......

Most receivers has a chassis as a ground.

Does "it works exactly the same"?
