Any idea when the SDR boards will be available to buy? And the cost?
I was planning an SDR myself when I first saw the Osmo design.
There are enough similarities to make yours worth buying - namely, the same FPGA I was
looking at.
I'm debating whether to buy the Lattice XP Brevia FPGA development kit. All else being
equal, I'd rather give YOU guys the money...

My own design ?
That uses a SINGLE 12-bit ADC, clocked at 48 MHz (same as USB clock, makes for simpler
circuit).
The "Zero IF Tuner" becomes a superhet design, with an IF output of 60 MHz.
Undersampling & downsampling in the FPGA gives a 12MHz bandwidth (actually less,
depends if IFstage bandwidth & degree of downsampling)
2-stage RF front end: 1-30MHz (si 570 is 61-90MHz) and VHF 140-150MHz (si 570 is
80-90MHz).
