I’m new to this, so I don’t know how to fix this. I think my install  
went OK on Ubuntu 14.04 with GR 3.7, but when I try to run Simple\_ra I  
get the following:

File “/home/jack/bin/simple\_ra\_receiver.py”, line 449  
title=“tpmodestr if interf == 0 else “Cross Power””,  
^  
SyntaxError: invalid syntax
