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 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.
Ellie

Hi Marcus and 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 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

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.

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:
