Hi Gerome, always nice to hear when people are able to build something that works nicely :) You might want to look at the gr-uhd pages in the GNU radio doxygen to learn how to send messages with timed commands to retune as you want, when you want. The Qt Sink also has a (normally hidden, can be enabled in the block config) message port input to change the center frequency. Throw together something that, once per second, instructs the USRP to tune at a specified time stamp.
