Heh... You know I wondered the exact same thing a few weeks ago.  Matt "informed" me that the .PCB files were never released.  I did find a copy of the gEDA files used to make the schematic drawings for the USRP from a older GNURadio mirror.  So much of what I'm seeing from Matt has been a move away from Open Source and more towards "Closed Development". 

I love how the USRP brochure has this blurb:

"Open Source Community
The entire USRP design is open source, including schematics,
firmware, drivers, and even the FPGA and daughterboard
designs. When combined with the open source GNU Radio
software, you get a completely open software radio system
enabling host-based signal processing on commodity platforms.
No software or licenses need to be purchased."

While to the letter of the law he did provide the above details, he has/will not provide all the information/engineering drawings necessary for people to roll their own boards or to import existing designs so they can be modified to suit a person's/organization's project.  I can understand why being this is how he makes a living, but at the same time he shouldn't be promoting the design as open source... just open architecture-ish...

On the other hand, the HPSDR is completely open.

So I guess I should be the first one to ask:

How will this affect the GPL and Open Sourceness of the USRP project?


More specifically, I see the pdfs of the schematics [1], but is there location to pull the .sch and .pcb files (or proprietary format equivalents) from?  I checked the gnuradio src tree [2], no luck...

thx,

Jason.
