RE: [Discuss-gnuradio] Can't transmit from USRP2

Hi Kjellsson, we had the same problem a while ago and we still haven't been able to fix it. It seems that USRP2 receives but doesn't amplify the signal so it is very weak compared to the noise. We also can't transmit from the USRP2 at all just like you. Have you been able to do something yet?

[Discuss-gnuradio] Tune failed with FLEX400 on side B

I have a new USRP board with FLEX400 MIMO B boards installed on both the A and B daughter card sides. I've created a simple spectrum display python app based on the example apps in gnuradio-examples/python/usrp. The my app works fine if I use the -R option to choose the A side device. However,

[Discuss-gnuradio] How to start to run the bbn code?

Hi! I am just starting to learn the GNU radio and bn code. I want to test some sample bbn code, however, can anybody tell me where and how can I run this code? Thanks! Angie -- Posted via http://www.ruby-forum.com/. ___ Discuss-gnuradio mailing list

[Discuss-gnuradio] GPU progress?

Hi, Use : r = usrp.tune(self.subdev._which, self.subdev, target_freq) instead of : r = usrp.tune(self.u, 0, self.subdev, target_freq)     Regards, Firas ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/list

Re: [Discuss-gnuradio] Question about USRP2

Hi Brian, I followed the instructions in the "GettingStarted" page. And I installed the gnuradio software in Cygwin based on the instructions in: http://gnuradio.org/trac/wiki/CygwinInstallMain In the last step, "Installing the USRP Driver on Windows", I found that the drive is for USB, but the

Eek, you didn't specify you're trying to install under Cygwin :) From Matt's USRP2 announcement: "At this time, the USRP2 is in "beta release" state. Not all of the software and/or features are currently ready for production use. The USRP2 is initially supported on Linux, and we anticipate that

RE: [Discuss-gnuradio] Tune failed with FLEX400 on side B

Firas, Do you mean to use the source_c tune method? Like this: r = self.u.tune(self.subdev._which, self.subdev, target_freq) I tried that and it does not help. The program runs fine with other tuners on the B side, such as the TV_RX board. Brian S. -Original Message- From: Firas Abbas
