AM is short for Amplitude Modulation, and by definition needs a carrier wave. This is more like controlled interference, still impressive though.

But on-off keying
is
amplitude modulation… just with a 100% modulation index..

Emitting a square wave as RF blithers all over the RF spectrum. At least put a bandpass filter on the thing so it stays in-band.
