[Discuss-gnuradio] bladeRF - gr-osmosdr - gqrx - bandwidth?

Hi, I am using bladeRF with gr-osmosdr, gnuradio 3.7 and gqrx, so far a fine radio. One thing, when using gqrx...I am limited to USB2.0 at the moment, so I use a sampling rate of 8 Ms/s, and in this mode I have big problems with images from the neighbour frequencies that are still within the 26 MH

Re: [Discuss-gnuradio] Signal composition and intermodulation filtering

Alessandro, You may be over-driving the DAC, which will generate very bad IMD. You have to be careful when summing signals as the total floating point value must never exceed +/- 1.0. If you are summing two signals then set your sinusoid amplitude to 0.5. Summing 4 set it to 0.25. Lou __

Re: [Discuss-gnuradio] Porting GR-AIS to GN3.7

Dangit. Missed one -- had renamed ais_rx.py to ais_rx but forgot to change apps/CMakeLists.txt to reflect it. Fixed, pushed the fix to master. Thanks! Nick On Thu, Sep 12, 2013 at 7:17 AM, Driesprong, Fokko wrote: > H > e Nick, > > Great work on the update of gr-ais. University is starting agai

Re: [Discuss-gnuradio] flowgraph with async messaging hangs on calling wait()

Any block can return "DONE" to indicate the scheduler that it finished its processing. Then the scheduler tells downstream blocks that they are DONE too. However, it's possible that you want downstream blocks to finish operating on samples that are "in flight" after the upstream block is marked

Re: [Discuss-gnuradio] Porting GR-AIS to GN3.7

H ​e Nick, Great work on the update of gr-ais. University is starting again, so I am running short on time. I have the following make-problem: make[2]: *** No rule to make target `../apps/ais_rx.py', needed by `apps/ais_rx.py.exe'. Stop. make[1]: *** [apps/CMakeFiles/pygen_apps_8ba3a.dir/all] Er

Re: [Discuss-gnuradio] Porting GR-AIS to GN3.7

He Nick, Thanks for the quick response! One last error in the make install. In the grc/CMakeLists.txt there are multiple xml files that are copied by cmake, but these files don't exists. I commented it out and everything works fine. I think you should correct that in the master too. ​Kind regards
