It is very hard to call ether of these projects fully open source. Im
still waiting for a project that applies the GPL to everything both
hardware and software.
At one time you could download the board and the software from VEMS
without any NDA.
I think the old board that could not control a Wideband is there
somewhere if you dig. I have not been following that project much in
the last three years or so.
I would also like a project to use a more modern MCU maybe an ARM or something.
