aprx was originally a receive-only APRS iGate software, now extended to do
|
|
digipeating, and Tx-iGate. It works on any UNIX-like systems with minimal
|
|
requirements of system services, or system libraries beyond basic POSIX libc.
|
|
|
|
The software is to be installed on a suitable UNIX-like system, and its
|
|
configuration file is then to be adjusted. Then it can:
|
|
* Handle arbitrary number of radio modems connected to itself
|
|
* Optionally relay APRS packets from radio receivers to APRS-IS
|
|
(http://www.aprs-is.net) network
|
|
* Optionally digipeat AX.25 packets with and without APRS NEWn-N
|
|
paradigm rules
|
|
* Optionally relay APRS packets from APRS-IS network to radio channel
|
|
(Tx-iGate)
|
|
|
|
This software is intended for very limited resources environment, like small
|
|
embedded-like machines barely able to run the operating system with TCP/IP
|
|
networking.
|
|
A receive-only Rx-iGate does not need any sort of licenses in most parts of
|
|
the world where radio amateur hobby is permitted to begin with.
|
|
|
|
On version 2, aprx has gotten the ability to do APRS Digipeater function,
|
|
Aprx Tx-iGate, as well as a variation of that called Viscous APRS Digipeater,
|
|
which is an excellent choice for a Fill-In digipeater like on a mobile
|
|
station. Viscousness means that it will listen for other copies of same
|
|
packet for a small configurable number of seconds, and if it hears same
|
|
packet only once, it will do normal digipeating for it.
|
|
|
|
aprx can optionall be used with soundmodem in place of a hardware TNC.
