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

- mikeyouse 8mo agoOn off keying at 1,000khz is AM transmitting though?
- crims0n 8mo agoAM is short for Amplitude Modulation, and by definition needs a carrier wave. This is more like controlled interference, still impressive though.
- mikeyouse 8mo agoBut on-off keying is amplitude modulation… just with a 100% modulation index.. https://en.wikipedia.org/wiki/On–off_keying https://en.wikipedia.org/wiki/On–off_keying

- benj111 8mo agoBy 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.
