I had been postponing (due to various valid reasons), building an Athlon64 box, but today morning I got around to do it. I went to the MG Road and bought an ASUS K8V-SE Deluxe MoBo, 512MB DDR2 ram, a 400W SMPS and an ATI Radeon 9200 SE w/128MB DDR ram AGP8x card. The ATI card is supposedly old, but since I do not care about 3D much, I think this was a good choice. I came back and compiled a new kernel with new drivers. It looks very good now. I need to check whether the cabinet is getting heated up and whether the ventilation is proper.
One of the main motivations to buy the new machine was for mor espeedy GNU Radio compilations and for access to USB2 ports which are essential for USRP/SSRP operations.
In another development related to gnuradio, I got the TI differential amp chip needed for SSRP ADC daughter card. But it looks like Linear Technologies, Inc, do not ship samples to India, so I am stuck at that point.
I hope to update the gnuradio debian packages more regularly and have created an alioth project for gnuradio. Any help in verifying the packaging is welcome.
