Here's a #HamRadio idea that goes a bit beyond radio.
Audio can be used to modulate movement/wiggle of a laser, or intensity. Spies can point a laser at your window & hear you talk inside your house, from across the street.
So, point a laser at a water tower a mile away, modulate it with FT8 or PSK31 tones, & someone else with a camera decodes it.
Possible?
