Hello,
Just wanted to let you all know that this problem is resolved. I followed the instructions here: https://www.reddit.com/r/RTLSDR/comments/3fx5t4/windows_10_and_rtl2832r820t_quick_and_frustration/ And now the flowgraph is working fine, with no errors! Have a great afternoon and thanks so much, Ellie ________________________________ From: Marcus D.

I agree with Glen that it looks like a great tool, and I look forward to testing it out -- feel free to post it on the Open Source Radio Telescopes mailing list as well in case there are folks there who would like to use it, too. I think I had done that in the past, but will do so again. So, back to the original question -- I am still not having any luck getting my RTL-SDR dongle to work with GNURadio on Windows 10, despite the fact that the dongle works just fine with SDR# on the same computer. Is this a known issue, and if so, are there any solutions I could try? I was hoping to use GNU Radio to test out a new antenna I built soon, so if anyone has any advice about this, again I would really appreciate hearing it! Many thanks in advance! I'm not a Windows guy at all, so I cannot help. Wish I could. Can anyone here help Ellie get GR-based "stuff" going with RTL-SDR on W10? Anything to look out for? Also, there's the ##rtlsdr IRC channel -- a pile of Windows folks on there.

It's a very impressive piece of work. If one has only one SDR, it is necessary to change the input number of channels to 1, I think(?) Then connect the 2nd channel (chan1) to the output of the source block. The modified .grc file works right away. Cheers Glen On Thu, Feb 22, 2018 at 11:36 PM, Marcus D.

I've tried to plug in my SDR and run the flowgraph (attached), but I keep getting the output below: Generating: 'C:\\Users\\Deana White\\Documents\\top_block.py' Executing: C:\Program Files\GNURadio-3.7\gr-python27\python.exe -u C:\Users\Deana White\Documents\top_block.py Win32; Microsoft Visual C++ version 14.0; Boost_106000; UHD_003.010.001.001-0-unknown gr-osmosdr c653754d (0.1.5git) gnuradio 3.7.11.1 built-in source types: file osmosdr fcd rtl rtl_tcp uhd hackrf bladerf airspy redpitaya Using device #0 Generic RTL2832U OEM usb_open error -12 FATAL: Failed to open rtlsdr device.

This is being done to prevent the application from crashing due to gnuradio bug #528. gr::pagesize: no info; setting pagesize = 4096 I've run zadig for the RTL-SDR, and it works just fine with SDR#. Do you have any advice as to why I might be having this problem with the GNURadio flowgraph? Thanks very much! Have a great evening and take care, Ellie I hope someone can help you, Ellie. My approach would be to install an operating system on your computer. :) :) [That was snarkasm, just in case it wasn't obvious.... ] Once you get it working, you (and Glen et al) might want to play with: https://github.com/ccera-astro/spectro_radiometer<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fccera-astro%2Fspectro_radiometer&data=02%7C01%7C%7C8d9abb52f00f49e9ccf008d57ab54e01%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636549841471892336&sdata=%2BYMCsIayCiKlERZybNHs4tg0Y97HaT%2FNYxpl2cY4rYM%3D&reserved=0> Cheers Marcus _______________________________________________ Discuss-gnuradio mailing list [email protected]<mailto:[email protected]> https://lists.gnu.org/mailman/listinfo/discuss-gnuradio<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.gnu.org%2Fmailman%2Flistinfo%2Fdiscuss-gnuradio&data=02%7C01%7C%7C8d9abb52f00f49e9ccf008d57ab54e01%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636549841471892336&sdata=aQcm7dEORvEXcdayYQo605sDtteStNuxg9fDaKccoyQ%3D&reserved=0>
