@Geojoek I'm not an expert on the various models. I've been using a 3B+ to run my station for a couple years now. Works great. It's hooked to a big screen HDMI monitor, runs Hamlib, my FT-450, runs WSJTX and Fldigi just fine.
So a 3B+ can definitely do the job but I can't tell you much more about it. Haha.
