People and policies
The University-Link repeater system is a loose confederation of amateur operators with no membership or dues, and it is run as a Benevolent Anarcho-Technocracy. That is to say: we make no rules for the people, but rather only for the machines, to stave off the inevitable entropy to which they succumb.
Our motto: “Illegitimi non carborundum.”
Several of us are alumni, employees, or fans of UT Austin. Since the early 1990s, we have operated this open repeater system in various forms, and all licensed amateur operators are encouraged to participate.
Financial support is accomplished by the core group financing the majority of equipment costs. These are actual equity holders in the system.
The trustees are ultimately responsible for the legal operation of the system. The system is registered through the Texas VHF FM Society. The trustees encourage freedom of speech, debate and discourse on any topic with free and unfettered communication of ideas and philosophies between all system users. We serve the community best when users feel comfortable to express their thoughts in a healthy and supportive environment. Normal rules of decorum and mutual respect are to be observed.
