Setting up SDRPlay RSPDX on Armbian running on an ODroid N2+ for network radio tuning.

Today I received my SDRPlay RSPDx device and decided to get it running on my remote radio server. I’m still not sure if I’ll run this remote or locally, but, wanted to have the option for whatever I do decide to do. The setup is pretty painless and involves a few commands. I’m going to assume you already have your Armbian server setup and can SSH to it and have a special user called ‘radio’ setup to run all of this as....

I was tasked with creating a simple dashboard for a client of ours that auto runs on boot of the computer. This weekend I sat down to work on this and here’s what I found. First, make sure you go with Rasbian Server edition of the OS.

Compiling (downgrading to) gnuradio 3.7.x on Ubuntu 20.x

Ubuntu 20.x comes with GnuRadio 3.8 which is based on python 3, and, the latest and greatest.

Making wxtoimg work on your 64 bit arm Odroid N2+

Recently I’ve gotten into RTL-SDR / HAM Radio and have been working on getting this cool package of scripts working that’ll automatically grab NOAA / ISS and METEOR data and decode it! Ran into an issue today with wxtoimg. Since it’s abandonware it’s not possible to compile it, and the only binaries are for 32bit arm, not 64bit, which is what my Odroid N2+ is. Here’s the quick way of making it work on your 64bit arm computer....
