Hi, Going over tutorial 2 http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GRC, trying the last example (a triangle wave, prove signal and a sine wave), which based on common sense and the image in the tutorial, should result in a periodic triangle shape in the waterfall scope. I

Adrian, your scattered questions indicate you have a long way to go before you can do anything useful with gnuradio on your own. I suggest you "study" these examples carefully: you'll discover that many people have put a lot of time and love into this and have provided documentation to answer mos

Little tip in general: in the python/ directory, look at the __init__.py file and remove the try / except around the "from xxx_swig import *". This will then actually _print_ the error preventing the SWIG import ... Cheers, Sylvain ___ Discuss-gn

Mac setup has v3.0.10. I upgraded on the Linux setup from 3.0.8, but it didn't make a difference. Good thought, though. My intuition is saying it is something with the fact that the viterbi call is a templated function. Either I'm not calling it quite right or SWIG isn't wrapping it correctly.
