Request for Comment: Creating a binary format output for rtl_power
by Bill Gaylord 09 Mar '20

09 Mar '20

Hello, I am working on making a binary format for rtl_power to save space on my server for observing the spectrum. I am wondering if anyone else would be interested in this idea. I am hoping keep the same format in terms of how the data is organized in the file but instead of using text use some form of binary format. For example for the date and time I think using a unix epoch timestamp would work. I am hoping to receive any comments or criticism. Thanks, KD9KCK

Fwd: gr3.7-qt5 --> CL Error: Unable to queue clear of spectrum buffer
by Sipos Csaba 25 Dec '19

25 Dec '19

Hi Sylvain, Resent it to the list as requested. I tried to use the 'gr3.7-qt5' branch today, and after successful compilation, I am getting this error message on the terminal: [+] Available device: 0:0 <NVIDIA Corporation> NVS 4200M [+] Selected device: NVS 4200M [!] CL Error (-59, /root/gr-fosphor/gr-fosphor/lib/fosphor/cl.c:438): Unable to queue clear of spectrum buffer I attached the complete output of the event, if you want to take a look. I also attached the screen how it looks during the run. OpenCL works fine otherwise, and I used gr-fosphor successfully on this same machine before. I am on Ubuntu 18.04.03 LTS with the proprietary Nvidia driver (v390). The gnuradio is 3.7.13.5 (comes with the ubuntu repo, not compiled from source). If you have any idea, or you need more info, debug log etc. please let me know. Regards, Csaba
