This is amazing! I would buy one in this price range.
What sort of help/contributions you need/expect from interested users? E.g. financial funding on CrowdSupply, beta testing, feature wishlist, etc.
Feature wishlist: please! Do send them our way. Especially if it's hardware, this is the right time!
and 3rd would be on the software side: support in Soapy and GNURadio (osmosdr) but I guess that would eventually come from the community.
This is exciting, and as supporter of previous open source SDR projects, I'm looking forward to more updates and news from you.
Here is a render of the enclosure (work in progress): https://i.imgur.com/AEYgLxU.png
And of course we agree on the software side! Soapy + GNURadio are a must. Hopefully my driver-writing skills are up to the challenge!
