@User sounds good. I was already planning basically the same thing anyway. Although starting with transmit since that's always easier. I was also planning on combining it with a fully open source DVB-S2(X) stack that we're implementing on a different OS project. In the first shuttle I submitted a fractional N PLL with second order MASH modulator and dither etc. If sims are to be believed it has a tuning range of 1.3 - 3.6 GHz. It uses a differential ring oscillator as the VCO since I steered clear of inductors for the first submission. So it's power hungry. I'm currently working on a inductor design setup that's nearing completion so I can add some LC topologies to the next submission and get some better performance.

That’s really great. Let’s plan on meeting this way we could split the blocks among us to avoid reinventing the wheel situation
