Hello! CSTART certainly sounds ambitious. I am happy to participate, maybe even contribute if there is a need. Both my undergrad and graduate theses are on communications subsystems for small satellites. I can work out your link requirements and data budgets if need be. I am a decent programmer as well, capable of using MATLAB, C/C++, Java, etc. I'm also pretty handy at Blender 3d and realtime graphics.
I also operate a mostly-functional groundstation, which is part of GENSO. This is basically a network of ground stations developed by ESA to provide globally distributed downlinks on amateur radio bands (mostly UHF/VHF… some stations are also adopting S-band hardware). It's still in beta testing at this point.
Let me know if any of this can be useful to the project!

It's great to hear from you. You're right, this certainly is ambitious, although, it can be accomplished with the help of a large community. My suggestion is that it would be most beneficial if you found a way to contribute somehow. Even if nobody has yet submitted anything that is relevant to your work, you could then provide the start it needed. For example, you could really help here, the communications workgroup for CLLARE (collaborative lunar landing and research expedition). Please, submit anything you can.
Have a look around. We are also in the early stages of creating a repository for our work. Feel free to clone this and add to it what you like.

Welcome aboard! It is great to have someone with really good comms experience onboard.
In addition to rpulkrabek's comments, I just wanted to point out a few more things:
- We have done a bit more planning work on the CLLARE comms stuff than the Wiki currently lets on. To see the full extent of our ideas, you should read the Communications System section of the CLLARE Overview Document. It talks a bit about the channels we want to have, using CDMA multiplexing, some software-defined radio ideas, etc. There is still heaps to be done which you could be a real help with, but we are not quite starting completely from scratch like the Wiki suggests.
- A little more immediately relevant than CLLARE (which is obviously a very long term project) is the OHKLA project. This needs a very basic communications system, basically just enough to be able to transmit GPS coordinates so that we can recover it after landing. Ideally, if it were possible without things getting too large or power hungry, it would be excellent if the rocket could broadcast some data or even video footage during flight, but I expect that due to our mass and size constraints we will have to just store this locally and view it after recovery. If you had any ideas to contribute on this matter it would be hugely appreciated (we really are starting out from scratch on this front).
You may be disappointed to find that we currently have no small satellite plans in the works. There was a proposal for something like this extremely recently, but some of us were worried we didn't have the man power to pull it off. A lot of new people have shown up today, though, and at least one of them (you!) has directly relevant experience for that project, so maybe that will change things? I'll let you know, anyway.

If S-band hardware becomes more common in the GENSO network, and many of the ground stations are manned by people like yourself who are interested in helping CSTART out, then the network could be a huge boon for us. We are quite concerned of the fact that we are not going to be able to afford time on gigantic dishes to pull projects like CLLARE off, we are going to have to rely on a widely distributed global network of amateur volunteers with probably relatively low end hardware (although I know some hams have fairly impressive set ups). Our communications system should definitely by designed in such a way as to maximise the feasibility of this.

Welcome to the team!
It is fantastic to hear about your communications background. This is an area that we could really use a lot of help on. You would be doing CSTART and CLLARE a huge service if you could come up with a workable communications plan.
Take some time to look around and get to know how we operate. We look forward to working with you.
