So I wanted to setup a small, cheap and effective receiver station, one that would allow me to receive almost anything and decode digital signals.

I first came across this idea when I bought my first RTL-SDR dongle and I started using it with SDR++. I found out that I could very easily receive from HF all the way up to Microwave frequencies, but without an antenna placed outside the signals were weak and the interference caused by switching power supplies and other electronic was enormous.

Placing an antenna outside introduced the need for the installation of a small computer with an SDR as close to the antenna as possible , to reduce interference.
I choosed a Raspberry Pi 3B+ for the job

On that Raspberry, I installed OpenWebRX plus, a webinterface that allows the remote use of your SDR.

I am still using that software, and since I choose the “plus” version (which is free) I have access to a variety of digital and analog decoders that would otherwise require much work to implement on a standard SDR++ installation.

You can see some examples of these decoders in the images below:
