Hi Eric, I solved the problem using your suggestion.
I changed the line 76 at u2_init.c: from: ad9777_write_reg(1, R1_INTERP_4X | R1_REAL_MIX); to: ad9777_write_reg(1, 0xB0 | R1_REAL_MIX); Then, I was able to tx frequencies higher than 50 MHz - [50,100] MHz. Thanks a lot! :D _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
