Re: GSOC 2020

Hi Narayanan, welcome here and thanks for your interest in GNU Radio and gr-radar. To get started with Python I'd use one the countless resources you find on the web. After that you would probably want to study the code of gr-radar itself (the tests usually use Python). For a general introduction

AW: gr-fosphor on AMD RX 550

Hi Sylvain, I attached the output of glxinfo and ran glmark2. The output is attached in this mail. I'm glad that this is supposed to run on my machine. Currently, I'm stuck with a 5.0 kernel because the system won't boot with newer kernels due to some MCS checks. I'm confident this is fixed in

Introduction for GSoC Participation

Hi everyone, I am Arpit Gupta, an Electronics and Communication undergraduate at the Indian Institute of Technology, Roorkee. I have been in touch with GNU Radio for about a year now. I successfully participated in *GSoC'19* with *GNU Radio*, building a *Block Header Parsing Tool*. More details re

RE: SDR transceiver having independent mixer and ADC sampling clocks

Thanks Brian. You are right, there exists three VCOs and PLLs in the AD9361 which can be controlled independently. AD9361 Reference Manual UG-570 shows a more detailed diagram in Figure 7. on page 20. The baseband PLL comprises an N/N+1 divider controlled by a high-precision sigma-delta modu

Re: gnuradio 3.8 errors with gr_modtool

Thank you all for your comments. I re-installed Ubuntu, thinking that it was a problem with my installation, but I get the same errors again. Marcus, I re-installed git, but I get the same error. I have no idea what is happening. I followed this steps 1 - Installed fresh Ubuntu 18.04.4 LTS 2- I

Re: gnuradio 3.8 errors with gr_modtool

Thank you Maitland. Is there a "safer" way of installing gnuradio 3.8? Matiland - there is not such a folder in /modtool/gr-newmod. I only have /usr/share/gnuradio/modtool/template On Tue, Feb 25, 2020 at 1:13 PM Maitland Bottoms wrote: > Laura Arjona writes: > > > 1 - Installed fresh Ubuntu 1

Re: gnuradio 3.8 errors with gr_modtool

just in case, I removed the only .pyc file I found under /usr/share/gnuradio/modtool/templates/gr-newmod/python/__pycache /usr/share/gnuradio/modtool/templates/gr-newmod/python/__pycache__$ sudo rm *pyc The same error occurs. Thank you! On Tue, Feb 25, 2020 at 2:17 PM Laura Arjona wrote: > T

Re: Excess bandwidth in constellation modulator

Thank you for your reply with the details. I do already read from the GNU Radio tutorial but wasn't fully sure. The equation now clear, just want to make sure one point from you. After the modulation(e.g qpsk) signal upconverted to RF, then the signal bandwidth still will be the same? Thank you ag
