Expanding Horizons

The Intersection of Amateur Radio and Computing

Speaker: Giovanni Moretti – ZL2GX and Graeme – ZL2GZ

Amateur radio is a hobby of exploring the limits of radio, electronics and digital technologies. Once licensed, you’re allocated a worldwide-unique callsign and can operate (and build) radio equipment capable of international and space-based communication.

Being an interest centred on electronic communication, there’s naturally a strong overlap with computing, with Arduino and Raspberry Pi and Linux being widely used. There are many facets to the hobby ranging from the seriously technical through to providing communications support for search-and-rescue (SAR), Civil Defence and Amateur Radio Emergency Communications (AREC).

In this talk, we’ll will give an overview, including how you can:

communicate internationally from your backyard (without the Internet or cell phones)
use both voice and digital modes on-air
design and build radio transceivers and antennas
send signals 2000km using just a Raspberry Pi and a micro-transmitter.
use Linux to link into international Internet-linked DMR and DStar (digital mode radio) networks
become involved in the ongoing efforts to build a regional radio-linked TCP mesh network

Should any of these pique your interest, we’ll finish by outlining how you can become licensed.
