Re: [Discuss-gnuradio] RTL-SDR device failed to open in flowgraph

2018-02-25 Thread Ellie White 
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

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.

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

Actually, you don't need to change the graph at all.

Specify a "dummy" file= device as the 2nd device:

  rtl=0  file=/dev/zero,rate=10e6

For example...
