[Discuss-gnuradio] gmsk error

[address@hidden]

I was trying to use the ggmsk-test.py, from the gnuradio-example directory,
and got the following error message:

$ ./ggmsk-test.py

TypeError: firdes_gaussian() takes exactly 4 arguments (5 given)

Can this test script still be used?

The example directory does not include a ./payload.dat file, so I generated
a file with just numbers using a text editor.  One numerical value, float
type, per line.
