I have been using Linux exclusively now for over 10 years and have not needed Windows. I am using a Raspberry Pi 4 8GB Ram, running Ubuntu Mate as my desktop, its running very nicely, it does not have a audio-in/microphone port, so I will need to buy a USB audio cable to use it for digital, something to look out for if your planning on using one, I downloaded all the fldigi programs, I want to get on echo using the Linux program "Qtel" using some USB mic/earphones but I have not registered with echolink yet, I am just getting started..... I am planning on ordering a 7" monitor for it, and setting up some kind of radio Go-Kit with a handheld. The Raspberry pi runs on 5v 3A, but the monitor needs a little more juice, I will need to build the Pi and monitor into something protective, both the monitor and Raspberry pi does not have a case. Its should be a fun project.
