I am with Evan here and would just buy a sBitx.
I am having a lot of fun enhancing and extending KD8CEC for picos and teensy, ?but after buying my own sBitx, I don¡¯t see my work ever catching up with a sBitx. It is a great radio! So I don¡¯t see my work ever being a reasonable upgrade path for ubitx owners. ?
I am going to continue working on kd8cec, and will make available Raduinos designs ?for pico and teensy. ?But doing so for my own fun and on my timeline.?
