I can't commit to pricing before I have decided on a partner for the distribution (DIY vs Kickstarter vs Crowdsupply, they all come with different costs and tradeoffs), but $550 is my target retail price for the Motherboard + Granita + Dev Board + CNC enclosure combo. $450 if you are happy with the Granita Lite board. Everything will be sold separately.

As a comparison, $550 would be 10x to 20x less expensive than what's on the market today for similar bandwidth specs (Aaronia Spectran V6 and Ettus USRP).

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.

We need volumes, so the best I can hope for is people join the waitlist and pre-order when we show a functioning prototype. We already placed sizeable orders with the manufacturers and have the first batch planned for September, but further batches are probably going to be delayed into 2024 (we can't start asking for preorders before the product is tested, which is going to take time, so we can't preorder those chips early like we did for the first batch).

Feature wishlist: please! Do send them our way. Especially if it's hardware, this is the right time!

Thanks. I have followed you on Twitter, and will discuss this with my RF fellas and get back to you on Discord or email. However, for now, I could mention 2 things that can be attractive to me as a radio amateur and RF hobbyist: 1. Any daughter board that can provide HF coverage, ideally with a few filters for the ham bands. 2. A proper shielding enclosure (shield from external noise, plus provide some heat dissipation)

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.

:-) The HF daughterboard is the only thing that's missing, I think. To be honest, I was hoping for someone to suggest a nice design on that front.

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!
