HPSDR PROJECT: We have combined the HPSDR and XYLO SDR groups into one project with common goals. There is a new domain and website for the project: http://hpsdr.org The XYLO SDR mailing list has now become the HPSDR mailing list. To join the list go to: http://hpsdr.org/reflector.html ATLAS BUS: This is the first attempt at defining the physical layout of the Atlas bus. The board ended up being 5.500" x 3.940", six slots, and 4 layers with the following stackup: 1. Ground Plane (top component side) 2. YBUS 3. Power Plane (+12,-12, +5, -5, +3.3) 4. XBUS (bottom side) Details are in the following document: http://www.philcovington.com/HPSDR/ATLAS/Atlas_doc.pdf After reading the document there are some other pdfs (such as the schematic) in this folder: http://www.philcovington.com/HPSDR/ATLAS/ For those interested, I'd appreciate if you'd please take a look at the documents and make questions/comments.
