Re: [Discuss-gnuradio] USRP2 - BasicTX first Nyquist zone frequencies

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
