From Zero to APRS in 10 minutes!

Let's build an APRS packet igate in under 10 minutes for just 99 dollars. This receive-only igate leverages a Raspberry Pi, Software Defined Radio, an LCD display and a rollup antenna. APRS igates relay radio packet information to the Internet for further processing and transmission. We can always use more igates, plus it's fun to visualize the traffic in real time. Texting, weather, beacons, positions and objects are displayed in this cheap-and-easy igate for just 99 bucks.
