Hi Bob,
   This is pretty easy to do (but, I can only tell you how to do it in C++)...

   set_clock_config() in UHD
Do you have some code snippet to share? Does the C++ version support streaming data from a slave device through a host URSP2 before sending all data via a single ethernet cable?

I am implementing our passive radar in C++ but I thought that GRC is nice for testing. I learnt yesterday that things are not completely available for GRC. But as our project needs to move on I would be highly interested if you can sync (PPS and freq.) two (or more) URSP2s via MIMO and (!) stream the data via a single gigabit Ethernet cable with the current UHD library? This would enable us to place our receivers at arbitrary locations without the need of pulse generators and a 10 MHz reference.
