Which OS for SDR

Post by chiefley » Wed Nov 24, 2021 4:00 am

I just purchased an RP 122-16, which I plan to use for amateur radio SDR experiments. I am familiar with Pavel's offering and I will probably be running that at first. But my goal is to become proficient at DSP on the FPGA and in C.

I have been in software development for about 55 years now, but somehow managed to avoid using Unix/Linux very much at all So I have somewhat of a learning curve for that as well.

My question are all about the various flavors of Linux.

1) Which OS is RP using in their distribution? Debian or Ubuntu or something else?
2) Which OS might be best for me considering my inexperience?
3) I notice Pavel uses a lightweight Linux called Alpine. Is Alpine required for his SDR software, or is it OS agnostic?

Thanks in advance for any advice you can give me.

Ubuntu.

Any of them should be OK.

Alpine Linux has fewer components and the components are easier to understand.

Some SDR applications are OS agnostic and can be installed via the application marketplace on the OS provided by Red Pitaya developers.

Some other SDR applications require features that are currently only available on my SD card image based on Alpine Linux.

However, the 122-16 board is not supported by the application marketplace. The only way to run SDR applications on the 122-16 board is to use my SD card image based on Alpine Linux.

Pavel,
Thanks very much for the reply. Reading more about Alpine it looks like the right choice for a server-like SDR. I will go with your distribution and learn from all the work you have done.
