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

I think I had done that in the past, but will do so again.Hi all,
Thanks for sharing that, Marcus! 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'm not a Windows guy at all, so I cannot help. Wish I could.
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!
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.
Ellie

Thanks again for the flow graph Marcus. It's a very impressive piece of work.If one has only one SDR, it is necessary to change the input number of channelsto 1, I think(?) Then connect the 2nd channel (chan1) to the output of the sourceblock. The modified .grc file works right away.
CheersGlen

Hi all,
I am an amateur radio astronomy enthusiast and I've been using an RTL-SDR (R820T) USB dongle for my projects; up until now I had been using a Windows 8.1 laptop, but that one is on the blink right now so I've switched to a Windows 10 computer. I've tried to plug in my SDR and run the flowgraph (attached), but I keep getting the output below:

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
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
Cheers

Hi Marcus,
ReplyDeleteI still have an USRP1 for radio astronomy. I have installed spectro_radiometer which works with a rtl. However, USRP1 is not listed as a device in spectro_radiometer. Is there anything I can do to rectify this? I have very limited software learning/experience.
Many thanks,
