OK, again, python script is successfully created/written, and it is runnable outside of GRC, the errno13 comes from execve call which is incomplete, can you see that, please? On Jul 7, 2017 01:27, "Cinaed Simson" wrote: > On 07/06/2017 02:57 PM, Jozef Lošonský wrote: >

I'm not behind my pc, but I think that it is possible to understand my issue, that py file is generated from any flowgraph OK, but "play button" press fails with Errno13 when "No GUI" (of course I'm not using any WX or QT block in such case). On Jul 6, 2017 11:48 PM, "Cinaed Simson"

Re: [Discuss-gnuradio] Observing Random Jitter in HackRF One in High Bandwidth with High Carrier Modulation

Post the gnuradio flowgraph you used. If you have a complaint with the HackRF hardware, post the complain on the HackRF mailing list https://pairlist9.pair.net/mailman/listinfo/hackrf-dev And if you're only getting 2 MSPS with the HackRF on your computer then you just have a slow computer -

[Discuss-gnuradio] Spurious Spikes in RX Data

Hi, I've recently gotten someone with Matlab to help me look at what's going on in my receiver. The image was created with matlab from data from a file sink connected directly to a usrp source. I am seeing spurious spikes when plotting I or Q, and I'm not sure where they could be coming from, or

Re: [Discuss-gnuradio] Successful installation of GNURadio 3.6.4.1 on Window XP and Windows 8

I have built windows installers for gnuradio that have been available for a bit over a year. They include 3.7.11.1 and just last week updated them to version 1.3, and include a wide variety of drivers and packages all purpose built for windows 10 64-bit. Hopefully that will save you some

Re: [Discuss-gnuradio] Observing Random Jitter in HackRF One in High Bandwidth with High Carrier Modulation

Do you actually have any evidence or plots showing excess jitter in the HackRF One and its effect on gr-dvbt demodulation, or are you just making it up? It sounds like you have come to a conclusion without understanding the problem. --n On Thu, Jul 6, 2017, 7:15 AM Stack Programer

Re: [Discuss-gnuradio] How does Rx Gain affect the incoming signal? GNURadio IEEE 802.11a/g/p

Hello Christian, The RX gain value controls the analog gain of the USRP's receiver. If you run uhd_usrp_probe on the command line you will see lines such as the following which show the gain range and step size: | | | RX Dboard: A | | | ID: TwinRX v1.0 (0x0091) | | |

[Discuss-gnuradio] burst_tagger trigger type

Hi everyone, I've been working with 'blocks::burst_tagger' for a while now and I wonder why the trigger input expects shorts. The impl only checks if 'trigger[i] > 0'. I would expect the trigger type to be 'char'. This would fit with the output of blocks like 'Plateau Detector' or 'Peak
