I am currently running GNU Radio 3.7.4 and I am getting an error running
the stock narrowband tunnel.py script. This is what I am getting:
[root@cobra narrowband]# ./tunnel.py -f 146.0M -a addr="10.2.8.104"

NotImplementedError: Wrong number of arguments for overloaded function
'new_tune_request_t'.
Possible C/C++ prototypes are:
uhd::tune_request_t(double)
uhd::tune_request_t(double,double)
I am not too sure what to do, I have looked up the error but I couldn't
find a solution. Anyone know what to do? Also, the benchmark scripts work,
it is just the tunnel script that doesn't.
Thanks
Jonathan
