[amsat-bb] Packet tutorial?

[Mark Johns]

I ran a fully automated PacSat gateway with WiSP years ago, but have been away from satellites for several years until recently. The QTH, rigs and computers are all different now.

Looking at what information I can find about digital birds today, I find it full of references to software I barely remember or have never heard of, and it's all pretty confusing. Has anyone written a RECENT beginners tutorial about DIGITAL satellites? I don't need to learn how to track SO-50 with my HT, but I do need to know about configuring TNCs, virtual or otherwise.--
