I think it's not considered to be an electromagnetic wave any more.

Yep. Explained.

Not in QM. I don't know too much about polarization, but it's not purely
based on "wave" stuff.

Sure. Particles of light hitting the metal of the antenna and knocking
electrons around causes radio reception, for example.

The change in quantum-amplitude has a frequency, because you're changing it
in a regular pattern at the transmitter.

It's proportional to the number of photons arriving. If by "amplitude" you
mean "strength", then yes. If by "amplitude" you mean what people who talk
about QED mean, then no.

As I said, the probability of finding a particle in a particular place is
based on multiplying complex numbers. But since you never actually find a
wave, but only interference patterns (so to speak), it's probably not a
wave. The "wave" properties don't explain *all* the different kinds of
interference, but only the kinds that interfere like waves do. There's also
interference patterns that are the opposite of what you'd get with waves
(lasing vs exclusion principle) that is *also* explained by the theory in
which everything is a particle.
You really should watch the lectures (or read the book) I pointed you to.
They do a very nice job of explaining it. Both the video and the book are
Feynman, who got a nobel prize for figuring out how to explain to other
quantum physicists how to figure out wtf is going on with quantum mechanics,
so it's really quite interesting.
