[Discuss-gnuradio] Sending Patches

2011-07-02 Thread Vincent W
Hi, I was wondering whether the email address for patches ( patch-gnura...@gnu.org ) was still valid. The wiki says it's for SVN, but seeing as the project is in git... Alternatively, what is the preferred form of submitting patches? May I post a patch file? Or would it be easier to set up a git

Hi, I'm trying to do some signal reconstruction and in testing and developing a concept design, I wanted to attenuate a test signal and hook it up directly to the RX port of my USRP2 through either the Basic RX or LFRX daughter board (and, eventually through my WBX board). My intention was to atte

[Discuss-gnuradio] USRP2 UHD Matlab Receiver Communications Blockset

om the uhd::usrp::simple_usrp class. I suspect it may have something to do with the uhd::io_type_t class, but, again, I'm not too sure. Has anyone had a chance to play around with this blockset, or know how it works? It looks _really_ neat, and appears to work with wbx boa
