Re: [Discuss-gnuradio] Vector average with decimate block

[Glen I Langston]

Hello Marcus and all,

Sorry to keep dragging on with this vector decimate.

I’ve gotten “vave” into grc but it is not running properly.

The grc messages I get are below:

I’ve tweaked the python and attached the .xml etc

qa_vave.py
Description: Text Data

vave.py
Description: Text Data

keep5.grc
Description: Binary data

vave_vave.xml
Description: application/xml

The QA code runs fine all by itself.  Some of the debugging print statements 
remain in the code

Sorry for the long, complicated email.

Suggestions?

Best regards

Glen
