Re: [Discuss-gnuradio] Installing GNUradio from source on Windows 7

Yep, that would be it (at least for the binaries). The binaries were building against 3.9, so you'll need a newer binary then. No worries, give that part a few days. For the script error, do you have permissions to create c:\gr-build? Are you running as an admin? Let me know if c:\gr-build

Re: [Discuss-gnuradio] Installing GNUradio from source on Windows 7

Hello Ernie, The TwinRX support was added in UHD 3.10. So unfortunately just loading FPGA images compatible with the Windows binary builds of GNU Radio will not be sufficient to get you on the air. I don't know what version of UHD Geof plans on including in the upcoming release. In the meanwhile

Re: [Discuss-gnuradio] IEEE 802.11 a/g/p transceiver - Data not being received at any frequency other than 5.89G

I did the following things that you suggested: 1) The gain is normalized and in the example file wifi_rx and tx it was set to 0.75. I changed the gain to a bunch of values but nothing is really changing. Also the scope plot in the receiver just shows noise and even when I get some decoded message

Re: [Discuss-gnuradio] Installing GNUradio from source on Windows 7

Derek, Geoff That might be the problem. The x310 came with version 13 for the FPGA, FW at version 4. But when you do a uhd_usrp_probe command when the x310 is first removed from its box, it comes back saying that version 33 of the FPGA build and version 5 of the Firmware is needed. I think

Hi there! I'm experimenting with a USRP, trying to transmit and receive a simple manchester-coded bfsk signal, and I'm stuck on how to properly build a message packet, and actually extract the data from the received waveform. Basically, I have the receive chain all functional, and I can see the

Re: [Discuss-gnuradio] Installing GNUradio from source on Windows 7

Hello Ernie, What version of the FPGA image is currently on your X310? I believe that the Geof's installer is linked against UHD 3.9 so the 3.10 FPGA images will not work. Regards, Derek On Mon, Jan 23, 2017 at 1:21 PM, Geof Nieboer wrote: > Ernie, > > I'm the

Re: [Discuss-gnuradio] Installing GNUradio from source on Windows 7

Ernie, I'm the maintainer of the scripts. I assume you are using the most updated git repo version. We're about to do a new release to coincide with the new release of GR, so there are a good number of changes from the last release. So you picked the default install location at that prompt?

Hi Mallesham, this is one of the cases where capitalization makes a difference: mbps=millibit per second is really not that much, and even 100 Mb/s would still be pretty tolerable, but that would only be a little more than 3 MS/s; what you're referring to is multiple 100 MegaBytes per second, so
