I don't get why PWM wouldn't work? Would the harmonics make the tuner ignore the signal?
Because the speaker is still slow, so if it got to it, there should be audio, but maybe the circuit filters out the PWM signal outright?

The PWM-based modulation is interesting, but as an amateur, I couldn't fully understand it or trust that the radio receiver reliably picks up the duty cycle as amplitude.
- anfractuosity 7mo agoIf you PWM a signal, I presume you could add a filter to convert to amplitude changes?
