[Discuss-gnuradio] More Options for Working with Sample Data Sets

I've been updating a number of modules following up on the GRCon working sessions around working with large and sample data sets. Yesterday I pushed another update to the new gr-sql module on github that incorporates HackRF and rtlsdr 8-bit streams to either convert with the command-line or direct

[Discuss-gnuradio] New GR-SQL Module

Hi everyone, Back from GRCon2017 (one of the best conferences I've been to) and had some time for some more module development. During the conference in one of the working sessions there was a suggestion for a module that would allow you to query really large IQ files with a SQL-like syntax. Mad

[Discuss-gnuradio] GNURadio/Module builds and std=C++11

Hi everyone, I've run into this on every Ubuntu 16.04 box I've installed gnuradio and OOT modules on and Google doesn't seem to have a nice clean answer (the search answer is always add a compile flag) so I figured I'd ask the group. When I build modules (gr-osmosdr in particular with libfreesrp

[Discuss-gnuradio] Major OpenCL Updates

Hi everyone. A number of you have asked me to keep you informed of any major updates on the OpenCL gr-clenabled project and the past couple of weeks have been pretty active. There's now a version up in the repo with a significant number of updates and all blocks have been validated (at least in t

[Discuss-gnuradio] What value is in in[noutput_items+1]?

I was looking back over the Quadrature Demod code and I happened to notice something unusual. The call to the Volk multiply conjugate routine appears to use in[noutput_items+1] on the last calculation. Here's the call: volk_32fc_x2_multiply_conjugate_32fc(&tmp[0], &in[1], &in[0], noutput_items);

[Discuss-gnuradio] How to tell Flowgraph to Stop in Work()?

I'm working on a module in C++ and when a condition happens I want my work function to signal to the flowgraph to stop. I saw some references for python to self._top_block but does anyone have a suggestion on how to do it in C++? Thanks! ___ Discuss-gn

[Discuss-gnuradio] PFB Clock Recovery Block (#1)

Thanks Marucs for pointing it out. Hadn't noticed. Will do. Hey Ghost, um, could you please not take the list into CC when replying to github issue discussions? It's pretty confusing. Best regards, Marcus ___ Discuss-gnuradio mailing list Discuss-

[Discuss-gnuradio] CorrectIQ 2.0

Hi everyone, been a busy week on OOT modules. While working on some other signal decodes I made a number of enhancements in the CorrectIQ OOT module. First, doing some testing I was seeing inconsistencies in the plotted waveforms due to inheriting from "block" instead of sync_block so that was fi

[Discuss-gnuradio] OpenCL/gr-clenabled Update

Hi everyone, I just pushed a number of updates/fixes to github for the OpenCL gr-clenabled project. While working on a different OOT block I found some variations between blocks using gr::block and gr::sync_block so now the OpenCL blocks are using the correct base types. There was also a compile

[Discuss-gnuradio] OpenCL FPGA Recommendation?

Hi everyone! I'm working on expanding the OpenCL modules for GNURadio and I want to test them with some FPGA's that support OpenCL. There's a few from Xilinx and Altera it looks like, but the ones I've seen are a bit pricey. Does anyone know of an OpenCL-capable FPGA card for under $1,000 for so

[Discuss-gnuradio] ATSC Decode Issues

Hi all, I'm having an issue getting ATSC to decode and I was hoping someone who has done it successfully may have some pointers. Here's the scenario Basic SDR antenna connected to an LNA4ALL feeding into an Airspy sampling at 10 MSPS using the attached flowgraph. I get a TS file and don't ge
