In this project I'm attempting to build a homebrew SDR receiver. My initial goal is to be able to receive broadcast FM. I expect the result to be a janky prototype, rather than a polished product.

The high-level hardware design will follow the phasing direct conversion approach:

I have ideas about a few of the details (e.g. I plan to use a Si5351 for the oscillator), but much remains to be worked out. My general approach will be to build and test the individual stages in isolation to help refine the design.

I'm currently imagining that I'll stream the sampled I/Q to a PC and do the DSP there. I'd like to write the DSP code mostly from scratch, even if it's crude, but we'll see what happens...
