Hello greatest SDR community to roam the earth, as we're progressing towards a merge of the next branch into master, which will actually bring us new features and challenges like Python3, QT5, YAML instead of XML in GRC and many, many specific improvements, I'll announce that we're switching over

It would be great to have both. Even if you can't do real-time decoding, you can get pretty far with non-realtime decoding. And at least, we'd have a reference design (even it's too slow). Although of course, I'd very much love to see RFNoC blocks for various other reasons :) -- M On 06/21/2018 0

There's the possibility that you have old images somewhere. Try running `uhd_images_downloader --refetch` to force refetching, and take a note of the destination (it's the first line of the output). Then, run uhd_image_loader with the --fpga-src option, and point it directly to the file you want to

Can you try recv_frame_size=1024 as part of the device args? -- M On 06/13/2018 03:23 PM, Ayaz Mahmud wrote: > Hi, > >   > > Yes, Its B210 and works with other example like tx_ofdm. > >   > > Ayaz > >   > > > *From:* M

GPS playback or simulation is *really* sensitive to underflows. If you have them, you're hosed. When playing back a GPS recording, I always read the file from a RAMdisk. SSDs (generally) and spinning disks just aren't fast enough usually, and sometimes your OS even gets in the way. On Sat, Jun 23,

Absolutely. It's kind of insane to build an RFNOC system without first having a software implementation. This will be exciting! On Mon, Jun 25, 2018 at 5:22 PM Martin Braun wrote: > It would be great to have both. Even if you can't do real-time decoding, > you can get pretty far with non-realtim
