Re: gr-rds modules documentation

There are examples in the examples directory that demonstrate how everything can be put together. https://github.com/bastibl/gr-rds/tree/maint-3.8/examples I'm not sure if or where they are installed on the packaged version. They show a complete FM receiver w/ RDS and a custom GUI. https://www.y

gr-rds modules documentation

2020-04-05 Thread David Hagood
I'm trying to find any documentation on the gr-rds modules - specifically, what do they expect to be fed with? It doesn't look like they accept IF, nor demodulated FM - it looks like they expect some other block between them and the FM discriminator. I've not found any docs on the WIKI, nor any

linking with GNU Radio FFT library

gr-acars is working very well with GNU Radio 3.8, all good. Now I'd like to add two improvements: being able to run multiple processing blocks in parallel (on multiple channels, which libfftw seems hardly able to do due to the non-threadable plan creation) and getting rid of the external FFTW depe

beautiful, thanks: adding #define CHUNK_SIZE 1024 set_output_multiple(CHUNK_SIZE); to the constructor yields resonable results N=1024: _N is zero N=1024: _N is zero N=1024: _N is zero N=1024: _N is zero Still not sure why my original option was not working, but this is definitely a fine solutio

I would use set_output_multiple() instead. See my previous e-mail for an example. https://lists.gnu.org/archive/html/discuss-gnuradio/2019-08/msg00188.html Ron On 4/5/20 01:36, jean-michel.fri...@femto-st.fr wrote: I am using the opportunity of porting gr-acars to GNU Radio 3.8 to re-write th

I am using the opportunity of porting gr-acars to GNU Radio 3.8 to re-write the processing algorithm. As part of this reorganization, I want to analyze the baseline standard deviation and detect the AM modulated message as a rise in standard deviation (ie custom squelch). Since there is hardly any
