Gee, you asked this like two months ago - I'm really far behind on the gnuradio list. Nevertheless (for the archives, I guess): After some research, I found (and ordered) the VIA VT1621L chipset. It works in linux and can support 2.665e+07 bytes/sec recieving and 2.317e+07 bytes/sec transmitting. You can get an add-on card that uses this chipset for less than $20. -- Caleb Phillips _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
