Yes, I modified it for UHD. A sample rate of 3.125Msps and a refresh rate of 5 fps worked just barely. If I reduced the sample rate to 800k it worked fine at 15fps. Anyway, my T42p laptop is pretty under powered for this type of stuff. :-) Elvis Dowson _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
