Without the proper knowledge or measurement equipment, I observed that the audio would fade out after a 30 cm distance. Combined with running it for mere seconds to test and record a demo, I assumed to be in the clear with the spirit of the regulations. Appreciate the reminder to be responsible with RF.
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.
That has been the bargain since WWII though. Pax Americana meant the US owned and enforced a global order, in return international trade and finance ran on its platform. Most Americans can't fathom how bad the alternative is to not being the world police.
This has been the dream since the dawn of time (agriculture is automating food production to some extent). The gains in increased productivity is rarely if ever distributed back to the workers though. We have concrete data on wage stagnation when productivity has been increasing in the past few decades. What makes you think it's different this time?
