Ultimate Direwolf TNC Installation Guide for Windows and Linux

This is this follow up to my introduction on Packet Radio. Direwolf is a software TNC, and one of the best things to happen to packet radio in the 21’st century. Gone are the days of expensive Kantronics TNC‘s. Direwolf gives us a free, opensource TNC, that is highly customizable for just about every need, and runs on about any system we have laying around. The TNC is the foundation of any packet radio system, that’s why we are starting here. This will serve as the reference point for every other tutorial we do in the packet radio series. But with great power comes some type of learning curve. That’s why I’m making the Ultimate guide to Direwolf TNC for Packet Radio. If you’re more of a documentation buff, and don’t need anyone to hold your hand, you can dig into the official docs here.

The following guide will get you a working direwolf installation with basic configuration. Proceed to the next post to tweak the settings and get it tuned for your radio. Although it includes instructions for VOX, I highly discourage it, and you will most likely not have a good time on anything other than APRS.
