> 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.

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.. https://en.wikipedia.org/wiki/On–off_keying
