Hi,
I'm very intersted in this project and will help to make things happen. I
can help in any part of the design, but I have more experience in FPGA
developing.

I don't know if this is kosher, but has anyone looked at the (vast array of)
offerings from Comblocks (comblock.com)? They sell FPGA IP cores for all of
their hardware, and it seems like it might be a good match for building a
basic I/Q acquisition system. Here's a full product list:
Well, may be an option for someone , but we are trying to get a cheaper, and
open-source, hardware and I hope we can do this.

Hi Marcus,
In your design there is only a single RX. I think it is better to build an
expandable board which can expand 2 RX 3 RX...
That will only introduce a little more cost but will meet much more people's
need.

This has everything in one place--commit to a single host I/O, and go
cheaper as a result.
The estimated BOM cost for this, including PCB would be under $100.00.
If you sacrifice very-fine tunability, then you don't need a DDC in the
FPGA,
Hi Marcus,
Who works on this project now?
Nobody, really, except that I've posted a few straw man designs.
Why choose USB as the interface to host. The USB interface became the
bandwidth bottleneck
in USRP1, so why use network interface?
USB-2.0 is relatively cheap to implement, which is
