Hi
Thanks marcus. I am new to Gnu Radio and Python. I am working on USRP N200 with RFX2400. I am trying to make digital-bert scripts to work for UHD. I made some changes in the code but i am encoutering errors. The latest error is shown below:

Can anyone help me out, how to resolve this error ? Attached is my little modified code.
