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

Hi Eric,
i felt like you when I read it, but take a look here
(http://gnuradio.org/trac/wiki/USRP2GenFAQ) :
"With Basic TX board, USRP1 can generate maximum of 44 MHz frequency,
What USRP2 is capable of ?
44 MHz is the highest frequency in the first Nyquist zone on the USRP1.
Much higher frequen

Hello,
I read in faq that the bigger frequency of the first Nyquist zone of
USRP2 is about 170 MHz, using a BasicTX daughter board.
My USRP2 couldn't get more than 50 MHz with this daughter board.
I'm using 9939 firmware revision.
Somebody observed the same problem with usrp2?
There is a way to
