Software defined radio AM band sample source

I'm interested in Software Defined Radio. I have basically no experience in any of the electrical engineering or math topics involved, but I'm reading... Rather than trying to deal with the hardware aspect of the antenna and the ADC, I imagine it'd be fun enough (and cheaper) to play with some pre-recorded (or even live!) sample stream...

F#/"Accelerator v2" DFT algorithm implementation probably incorrect

I'm trying to experiment with software defined radio concepts. From this article I've tried to implement a GPU-parallelism Discrete Fourier Transform. I'm pretty sure I could pre-calculate 90 degrees of the sin(i) cos(i) and then just flip and repeat rather than what I'm doing in this code and that that would speed it up. But so far, ...
