Hi Ivan,
Try building with the gr-ettus maint-3.7 branch.

Re: [USRP-users] Direction finding based on USRP E310 board
Hello I am trying to install RFNoC for uhd 3.15. As far as I understand,
this version supports RFNoC. And in order for me to have blocks in
gnuradio, as I understand it, I need to install gr-ettus. But when
installing, I get this error The found UHD version (3.15.0.0-3build2) is
not compatible with the version required (4.0). how can I be in such a
situation?

Re: [USRP-users] Direction finding based on USRP E310 board
Ivan,
to the best of my knowledge, there should not be any RX1 port.
Instead, you should have two (coherent) channels "A" and "B" both
allowing you to select one out of two available antenna ports when
receiving ("TX/RX" or "RX2").
Cheers,
Julian

Right!
Be careful, DOA estimation using only 2 antennas works but it’s not
so accurate.
Enjoy!

Re: [USRP-users] Direction finding based on USRP E310 board
The two channels on an E310 are already time synchronized and phase coherent. You’d only have to callibrate and remove external phase effects.

[USRP-users] Direction finding based on USRP E310 board
Hello. I am interested in the possibility of implementing a prototype direction finder based on the USRP E310 board. Since I have it in stock. Interested in basic questions such as is it possible to synchronize the phase on two channels and are there any examples of such attempts? Perhaps someone can give some instructions on this matter, since this is all at the level of an idea. PS Other USRPs I have no way to use at the moment. ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
