Re: [Discuss-gnuradio] USRP2 Diagnostics in GRC

[Josh Blum]

Wow, how did you find this ancient version of grc?

Anyway, here is the note from my website:

Please use the grc that is bundled with the current gnuradio master or 
the gnuradio 3.2 release. It has a years worth of work and improvements 
compared to the last versioned release of grc (0.70). In addition, the 
grc bundled with gnuradio is guaranteed to evolve with gnuradio; whereas 
the older non-bundled grc will stagnate and cease to be compatible with 
newer gnuradio releases.
