#5With some filtering on the output to knock down harmonics and aliasing noise, and as long as the power output is low enough, this could actually be legal in the US. IANAL, etc, but this is my understanding:
It's actually ridiculously tricky to measure transmitter power output in the terms that the FCC regs are written in, but the rule of thumb is that, given the receiver sensitivity of a typical radio, if you lose the signal when you're more than 200 feet from the transmitter, you're probably in the clear.
This means a perfectly legal power level would be more than adequate to cover your house, office, hackerspace, or whatever.

#6I remember going to the drive-in movie theater in the 80's. You had to tune your car radio to a specific frequency to hear the movie audio. If this device had existed back then, you wouldn't have needed to tune your car radio at all. I doubt the neighbors would have liked that though. As an aside, I remember being jealous of the neighbors because they got to watch all these movies for essentially free. The irony is that today, we're bombarded by content, it's become essentially free.

#7It's kinda refreshing that the "Legality" section is entirely concerned with power and frequencies, and not at all about the IP rights around Swift's music.

#8> I'm not convinced that I'm operating anywhere close to peak efficiency. There may be some huge DSP-specific shortcut that I'm overlooking - I'm certainly no expert. But the current code works well enough.
Something along the lines of taking the FM at baseband, transform to frequency domain, copy result n times and shift the coefficients to the right indices, much wider ifft to RF should work, right?

#9Ham radio has gotten me into more devious activities than I'd like to admit... but that's half the fun of experimentation :)
Well done :)

You still need to tune it but there are many "center frequencies" that can be tuned instead of just one. So, you wouldn't have to tune far but you would still have to tune :) If you had a knob like most radios in the 80's it would save you from cranking the knob several times to get the dial into the right range before fine-tuning.
