I am using GRC version 0.7. I installed from Add/Remove Programs. I have Gnuradio 3.2 as shown in Add/Remove Programs. How can i upgrade my GNU/GRC installation to work with USRP2?

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. and wiki page http://gnuradio.org/redmine/wiki/gnuradio/GNURadioCompanion -Josh On 03/31/2010 07:19 AM, Umair Naeem wrote: > Hi, > > I have a problem concerning USRP2.
