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).
