Yes. From the FAQ (http://www.gnuradio.org/trac/wiki/USRP2GenFAQ): Does the external frequency reference have to be 10 MHz? Can I use 100 MHz? Actually, you can use 100 MHz as well, you will just need to change one line of the firmware to set the R-divider on the PLL. You can use any frequency for which the following equation has a solution: 100 MHz / N = Ref / R for which N and R are integers and smaller than 32,768 _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
