Hi Brek, You clearly are a great electronics hobbyist... maybe its also your job. I used to be, so I've subscribed. I've watched a few of your videos, most of us what to see more of the design and build elements, circuit diagrams, and the like. If you do that you'll get far more interest from viewers... just looking at the end product is not exciting. Take a leaf out of the Movies - scripts always have an intro, a build-up, and a climax. The climax is seeing it work or fail. Without showing the journey, there is no holding on to the viewers' interest... and no view stats. Don't give up, your on the road to success and you are almost there... just expand the video content to show your entire process from concept, design, build then successes and failures.
I’m already sure I won’t be interested in a comprehensive implementation of APRS. It’s the greatest shitshow I’ve ever seen. I’m normally up for a challenge, but I don’t even like it. Try taking a read of it’s spec (APRS101.pdf). This project has a couple of specific reasons to exist, and implementing those isn’t such a big deal.
