<p><b>New page</b></p><div>Running APRS on Linux can be done in a few ways.<br />
<br />
<br />
The short version can be found here: [[Rpi-aprs-what-do-i-need]]<br />
<br />
<br />
<br />
If we assume a setup that can:<br />
<br />
* receive packets that come in from over the the air<br />
<br />
* receive packets that come in from over a network adapter (e.g. connected to the Internet)<br />
<br />
* transmit packets over the air (i.e. to 'rf', radio frequency)<br />
<br />
* transmit packets to a network adapter (e.g. to the Internet)<br />
<br />
<br />
..then the following components are identified<br />
<br />
<br />
==A device to receive the packets==<br />
<br />
* a ham radio (e.g. base station or handheld transceiver)<br />
<br />
* SDR (software defined radio)<br />
<br />
* a Network Adapter (e.g. from the APRS-IS network on the Internet)<br />
<br />
<br />
<br />
==A device to convert analogue (audible) signals to some form of digital signals==<br />
<br />
(not required for packets originating from a network adapter)<br />
<br />
* TNC (Terminal Node Controller)<br />
<br />
* some fancier ham radios have a built in converter that just spits out RS-232<br />
<br />
* a computer sound card (either in a laptop, or a dedicated PCI or USB device)<br />
<br />
* SDR (software defined radio)<br />
<br />
<br />
<br />
==Protocol Software that converts the digital signals to APRS packets== <br />
<br />
* TNC (e.g. reads from an AX.25 interface or directly from a serial or USB port)<br />
<br />
* soundmodem (converts soundcard signals to the AX.25 protocol)<br />
<br />
<br />
<br />
==Application Software that processes the packets based on their information==<br />
<br />
Most of these programs can be configured to listen to serial devices or network adapters, including the AX.25 interfaces.<br />
<br />
* TNC (Terminal Node Controller)<br />
<br />
* APRS client (aprx, xastir, direwolf, UI-View, etc..)<br />
<br />
<br />
<br />
<br />
One of my first experiences with APRS was to configure a receive and transmit station (a digipeater) using:<br />
<br />
* a basic USB sound card <br />
<br />
* a 2-metre handheld transceiver (Icom IC-P2AT, maximum 5 Watts output power)<br />
<br />
* a Raspberry Pi 'single-board-computer'<br />
<br />
<br />
I have created a dedicated page for this project: [[aprs-on-rpi]]<br />

Below is a collection of configuration files that have been known to work:<br />
