Another of those glaringly obvious questions:
Proposition: In an idea system we know that radio reception can only
occur when a receiving apparatus conducts radio signals
from its antenna, through intermediate circuits, to ground.
Then: Removing either or both the antenna or ground renders the
Conclusion: No matter in what form, all radio receivers (and
transmitters) must be grounded even if no attachment to the "earth
is obvious. A ground must exist if the receiver functions. Where
is the ground?
Here I have a Sony 2010 tuned to a local station. It uses batteries
and has no attachment to the power distribution system
and thereby is not grounded through it. How does the radio signal
"return" to the transmitter?
A space probe in deep space sends a signal back to its Earth
controllers. Since the signal is received
we know there must be a "ground." Where is the "ground?"
