Error message, trying to start Simple_ra

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/”, line 449
title=“tpmodestr if interf == 0 else “Cross Power””,
SyntaxError: invalid syntax
