Re: [Discuss-gnuradio] GNURadio Windows Errors with OsmoSDR

Hi Kyeong This is running a GRC file inside of GNURadio Companion. Something is indeed broken. I simply ran the Win64 installer for GNURadio from the Windows builds site linked by the GNURadio wiki. I recall last year I had this same issue on my Windows system and gave up using GRC on

Re: [Discuss-gnuradio] GNURadio Windows Errors with OsmoSDR

Hello Patrick: Are you running a GNU Radio Python code? Or, are you running a GRC file using GNU Radio Companion? If you are running a Python code generated from GNU Radio Companion, you should be running that code using "GNU Radio Command Prompt" (which comes with correct library PATH

[Discuss-gnuradio] GNURadio Windows Errors with OsmoSDR

Hi all on the list, I've been tearing my hair out trying to solve an issue I'm having with a clean install of GNURadio using the Windows builds. When trying to run a simple flowgraph, with an RTL-SDR source connected to a frequency sink, I receive the following traceback: Traceback

[Discuss-gnuradio] Router (or IP decapsulation)in GNU Radio?

Dear All, I have recorded a RF Signal for reverse engineering. I found it is a BPSK modulated HDLC/ Frame Relay data. The recovered data itself is IP encapsulated, exactly as explained in: https://www.tutorialspoint.com/ipv4/ipv4_packet_structure.htm The data itself is UDP. In summary the

Re: [Discuss-gnuradio] Difference in Spectrum Analysis between Wx and Qt?

Hi Marcus, Thanks for your reply, I connected a File Sink and later sourced the file into both Qt and Wx instruments, with the same result. I expected this to happen, as for the hardware setup I did not change a thing between Qt and Wx measurements, it was just a matter of switching between Qt

Re: [Discuss-gnuradio] Difference in Spectrum Analysis between Wx and Qt?

Hi Martijn, Can you please use a file sink to record the signal, so that you can verify that it's different when visualized with Qt and Wx? Because: there might be a scaling difference between Qt and Wx GUI, but the math should really be the same inside. I'd hence assume that there's really a

[Discuss-gnuradio] Difference in Spectrum Analysis between Wx and Qt?

I'm using GNU Radio v 3.7.11 on Windows 10, 1903 with Intel i5-3550 CPU and on Linux Ubuntu 18.04, with i7-3720 CPU. Both have 16GB mem. Further, I have connected a HackRF One with firmware 2017.02.1. To the HackRF One I have connected a Siglent SDG1025 Waveform generator, with external GPS

Re: [Discuss-gnuradio] Combining blocks

Hi Tom, that's **exactly** what hierarchical blocks are for. Make a new flow graph. Set the flow graph type to "Hier Block" (instead of "Qt Gui") in the "Options" block, and __give it a good "Dd" and "Title"__. You should probably also define a descriptive "Category Name", e.g. "[Resamplers]" if

Re: [Discuss-gnuradio] How to introduce regex in GNU Radio block?

Hi Sébastien, Thank you for your reply. I am really glad to know that what I am doing is meaningful !! It will be much easier if the module use defined interface. I will try to implement this block the way as you suggested. On the other hand, I've ever thought about use the XML file output
