Re: [Discuss-gnuradio] Block key "rtl2832_source" not found in Platform

[Michael Dickens]

Hi Giulio - It looks like GNU Radio is trying to mix and match between Python 
2.6 and 2.7.  This, in general, is not advisable; try to coerce GNU Radio into 
using one or the other.  Fix that first, then see if there's still an issue.  
If so, maybe someone with knowledge of the "rtl2832_source" can help.  Good 
luck! - MLD
