Hello All, I have been using my USRP1 mainly on an older Linux PC with GNU radio 3.3 . Now I wanted to give it a try on W10 and a modern PC, but when I run a RX benchmark_rate test with latest UHD 3.15 but also 3.10 the command window gets filled up with DD messages and number of dropped sam

Hi Andy, You'll probably want to use gr-satellites instead of direwolf. https://github.com/daniestevez/gr-satellites You can record a pass using GNU Radio using a File Sink. Regards, Nate Temple On Sat, Feb 15, 2020 at 6:01 PM Andrew Stamp wrote: > Hi, > > I’m looking for assistance with sett

Hi, I’m looking for assistance with setting up a raspberry pi, with Direwolf and gr-satellites, to receive and decode from the Phoenix cubesats being deployed on February 17. Specifically, they will be ax.25, using GMSK. Is it possible to use a raspberry pi to record the audio, and record the wate

Hello, I apologize in advance If I sound not right. To follow up on my inquiry: Well, I get to know how to find the bandwidth, as our constellation modulator uses some root raised cosine filter, it needs to have a roll-off factor which in another way excess bandwidth. Bw=(1+alpha)*T = (1+0.7)*(6250

Marcus I see where I went wrong. I am using ettus because I have an Ettus B210 SDR. as for setting up the rest I will upgrade to ubuntu 19.10. For my project I require gr3.8. I am noticing that with several dependencies for 3.7 based applications are no longer available. so upgrading everything
