I heard about gnuradio since a year ago, and well realize the power of
the power o software combined with especific hardware
like URSP could make awesome things in radio astronomy, GSM networks
researh, Ham radio and so on.
But i also discover (may be i’m wrong) that the only avaliable proven
hardware to work with is URSP, wich is a great device but is the only
one out there.
I’m writing here to as about hardware the requirements/steps to a
hardware be considered a posible new device to be integrated in
But also i want to introduce a copyleft board called SAKC , wich in
general terms is a SoC chip plus a spartan3E fpga plus IO,
surely is too short description so here is a block diagram to chek .
As you can see there is no ADC DAC modules yet, but may be you can
and review this board as a possible gnuradio new hardware. And in the
ways support copyleft hardware devices. And knows also copyleft gnuradio
I’m not a hardware or sofware developer, i’m just learning from all this
projects so dont blame me if i used a wrong term.
But i’m conviced of the importance of having our own free/libre software
and coplyeft hardware. 
Thats all, i’ll waiting for your answers/comments that also will be
forwarded to qi-hardware devel list.
