Re: [Discuss-gnuradio] varying the bandwidth of a signal in GRC
Hi Jason, Please go through this, http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsCoreConcepts#Sampling-rates Try 1. Varying USRP sample rate and observe the output using FFT sink 2. In the flowgraph use an interpolator (rational resampler) just before your USRP sink, vary the interpolation factor and check the output. Things will be more clear then.

[Discuss-gnuradio] rtl_tcp issue
Hi! I hope this is the right place to ask my my question, otherwise, please let me know where i can ask... I'm playing with rtl_tcp since 2 yrs (or more...), but very very very often (almost always), when i connect to rtl_tcp with ANY program like sdrsharp,gqrx,and so on, i get this in the console: "ll+, now 1" "ll+, now 2" "ll+, now 3" . "ll+, now 461" "ll+, now 2" "ll+, now 3" "ll+, now 4" and the client is sometime very slow... Using direct usb dongle the problem disappear. Tested on local connection on a very fast pc, tested on a raspberry and tested on 127.0.0.1 What can it be? Many thanks for your patience! ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] Cmake rule to compile GRC files with GRCC
Hi all, In my third party gnuradio project - gr-gsm (https://github.com/ptrkrysik/gr-gsm) - I'm using gnuradio companion to create apps. Different versions of gnuradio companion generate python files that may be incompatible between different GNU Radio versions. Therefore if the user decides to compile gr-gsm it would be best to compile python files on his machine, for whatever version of GNU Radio he has. I'm is looking for someone who know how to do this with use of cmake. There is a file taken from GNU Radio which is in https://github.com/ptrkrysik/gr-gsm/blob/master/cmake/Modules/GrMiscUtils.cmake. It had GRCC function which was suited for GNU Radio (although it was not really used in GNU Radio). I've tried to adapt it to gr-gsm case but it caused more problems than it solved. If you know how to write a CMAKE rule compiling GRC files with grcc - please help.
