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.-- Mark D. Johns, KØMDJ Decorah, Iowa USA EN43

Not sure about complete beginners guides but because pretty much all digital sats today (not counting telemetry only sats) are APRS style unproto digipeating and not store and forward like it was years ago APRS is a good starting point to look into.

One site you could have a look at is the APRS Sat page from WB4APR, it is a bit messy because Bob likes to add info to the page rather then completly rewrite as information gets updated. http://www.aprs.org/iss-faq.html

Most people prefer to use UISS as the main software because it has been designed specialy for the task. http://users.belgacom.net/hamradio/uiss.htm

For virtual TNC it is recomended to use UZ7HO soundmodem http://uz7.ho.ua/packetradio.htm or direwolf https://home.comcast.net/~wb2osz/site/

Both preform better then most hardware TNCs especialy older ones that have started to drift in tones.
