The tape/rope does. With radio, it is the electric and magnetic
(vector) field (the electric and magnetic components of the
electromagnetic [tensor] field) that oscillate.

What idiocy is this!! Do you really believe a magnetic tape is oscillating while it is sitting in a cupboard somewhere?

and it is able it reproduces the signal that wrote to it. Nothing in
the radio signal oscillates for the same reason.

Confused nonsense.

if no oscillation, then there is no signal, and will not propagate,

In doesn't oscillate dopey. It induces an oscillation because of its
static spatial waveform

Correct. The oscillation of the fields is initiated by oscillating electriclly charged particles (electrons) in the sender's antenna, and converted back to sound from the oscillation of electrons that are
therefore oscillating in the receiver's antenna:

Gibberish. Such a nonsense, it is not even wrong.

No. I have suggested a model to explain to you how electromagnetic waves _propagate through space_.

_You_ are the who has suggested for some reason a "magnetic tape". Whether
the tape is magnetic or not is irrelevant to my model, as I indicated by suggesting a rope instead (which is not magnetic).

Gibberish. Read, think, post; in that order.

Pseudoscientific word salad.
