Hi,
Am I not supposed to put USRP blocks within a hierarchichal block and if so,
why?
Very strange minimal example (Ettus USRP X310, Windows 10, gnuradio 3.7.13.5):

Works and with a spectrum analyzer I see the tone at 916 MHz.
Then I do nothing more than putting the Signal Source and USRP Sink into a hier
block and using it:

It's hard to believe but true: The spectrum analyzer stays silent! It doesn't
output anything.
All messages on the console are same as well: The FPGA image gets loaded onto
the USRP and it starts.
For a brief moment at startup, the spectrum analyzer shows a small tone at
916MHz which disappears again.
Thanks,
Luke
