Building an APRS iGate using a Raspberry Pi and a TV tuner dongle

I’ve been messing around with APRS – the Automatic Packet Reporting System – for some time now and had noticed an absence of coverage in my local area. The end goal of APRS is to feed packets (which might be position data, weather reports, messages or other information) to the APRS-IS (which can be viewed at aprs.fi), and this is done via digipeaters and iGates. A digipeater merely re-transmits packets, until they reach an iGate, which feeds them to the Internet.

My local RAYNET group frequently uses APRS for position tracking at events, but often position reports fail to reach control due to a lack of APRS coverage. I therefore deemed it would be a good project to make a portable, lightweight iGate that could be deployed quickly. Continue reading “Building an APRS iGate using a Raspberry Pi and a TV tuner dongle”
