> Raspberry Pi Pico as AM Radio Transmitter

The fact that you are receiving it with an AM radio, doesn't mean that you are transmitting AM.

By the same token, if the AM radio is receiving something other than AM, it isn't an AM radio.

Or we could just use words that are useful for communicating things.

On off keying at 1,000khz is AM transmitting though?

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.
