[Discuss-gnuradio] Creating a UHD Sink block

[Brooke Hayden]

I am having trouble with the GNU Radio block that I have created to use as an alternative to the regular UHD USRP Sink block provided by GNU Radio. The file compiles, but there are errors when I run it in a python file. The Python file works fine if I use the GNU Radio UHD Sink, but not when I use mine. I have included the errors below. Thanks!
