No way in heck are you going to be able to run at 25Msps for even a *single* USRP2, let alone multiple ones. I tried a 25Msps usrp2_fft.py on my atom D510 system (which is dual-core at 1.6GHz), and it couldn't keep up. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
