I have not finished watching the video yet as this is a busy day. However, I will. And I would be very interested in any Raspberry Pi information for using it for Amateur Radio tasks. I have a Pi 4B, but as yet have not set it up. I am having trouble getting the video connection to work. I will figure that out when I have a chance. I got it with the intention of using it for exactly what you mentioned. Well, except for the gaming. I do want a back-up e-book, .doc, and .xls reader, along with the Amateur radio tasks, other communications monitoring, and weather monitoring and forecasting.
Thank you, beorn. You are a real asset and resource for us.
Just my opinion.
