[Knightsqrss] QRSS grabber network?

Clayton G
It looks like I've set the world on fire - or at least a few Knights! Thanks for the feedback. To answer a few questions: The details of my receiver can be found in my design entry at:
I am however further developing the software including improving my test server application.
The receiver sends raw sample data. This is currently IQ sample data at about 600SPS, but there is some work needed to optimise this - sampling rules indicate it could be a lot lower. I think it works out to about 3.5GB per month, which could be an issue for those of us with data limits (which is the usual case here in Australia). I think there is still plenty of scope for data compression to keep the traffic down. I don't think the CPU would have the processing power to perform the actual FFT operation.
My intention was to use a VPS (virtual private server) service to host the network. Some of these services are available for <$10 per month. I have yet to follow up with such services to see if the system is compatible. A donation button on the website would help fund the system.
However the network is not something I can tackle alone. As much as I'd like to, I'm current knee deep (or more like neck deep) in KiwiSAT development so my spare hobby time is limited. I can probably address the design and firmware needed for the receivers, but someone to help with the server is needed.
My idea for data presentation was a web pages with rows of images (one per receiver) showing activity over the past hour or so. Smaller images would be shown by default, with the option to enlarge for more detail. If we have a large number of receivers we could have limited stations shown on the home page by removing locations that are near each other.
The server would also have the ability to manage receivers, including the ability to upgrade firmware. Receivers can therefore be set and forget in operation. I still have a lot of unanswered questions and ideas, but if there are a few people interested in helping build such a system, I'm willing to do my part and make it happen!
