Hi,

Maybe a dumb question, but up to now I was using gr-dvbt2 downloaded as  
source, compiled and installed. Now gnuradio brings this stuff by  
default.  
So I wonder what may happen when I remove the duplicate blocks from the  
gr-dvbt2 package with a make uninstall. Will my grc files still be  
functional by using the new and probably identical blocks, or will I  
have to  
manually rebuild my grc files?

Ralph.

You’ll have to rebuild them. All the block names have changed from  
dvbt2\_xxx to dtv\_dvb\_xxx (for blocks that are common to both DVB-T2 and  
DVB-S2) or dtv\_dvbt2\_xxx.

However, there are new versions of vv003-cr23.grc, vv009-4kfft.grc and  
vv018-miso.grc in gnuradio/gr-dtv/examples that you can start with.

OK, so far everything is fine, it was no big deal, works great.

Can you provide a link to the transport streams for dvb-s2 your examples  
are  
referring to?

Thank you very much!

Ralph.
