- afskmodem soundmodem for 300-19200bd afsk/fsk modulation, 2 channels
- aprsmap powerful aprs-viewer using open street map
- gps2aprs aprs-tracker using connected gps-mouse
- gps2digipos generate pos-beacon for digi/igate using connected gps
- sondemod decode data produced by a RS92 wx-sonde, received with sondeudp
- sondeudp soundmodem for RS92 wx-sonde
- udpbox intelligent aprs-digipeater
- udpflex interface between serial RMNC/KISS and AXUDP
- udpgate4 aprs-igate
- udphub L2-switch for AX25, one AXUDP port from a digipeater interfaced
to many users
- udprfnet
The whole toolchain is copyrighted by Christian Rabler (oe5dxl) and many others
who contributed code (see the actual source code and the git commit messages
for details). You can redistribute dxlAPRS toolchain and/or modify it under
the terms of version 2 of the GNU General Public License as published by the
Free Software Foundation. Most of it can also be distributed, at your option,
under any later version of the GNU General Public License -- see individual
files for exceptions.
Also note that the GPL and the other licenses are copyrighted by the Free
Software Foundation and other organizations, but the instance of code that they
refer to (the dxlAPRS toolchain source code) is copyrighted by me and others
who actually wrote it.

Like many other projects, dxlAPRS toolchain has a tradition of including big
blocks of License headers in all files. This not only blows up the source code
with mostly redundant information, but also makes it very difficult to generate
License Clearing Reports. An additional problem is that even the same licenses
are referred to by a number of slightly varying text blocks (full, abbreviated,
different indentation, line wrapping and/or white space, with obsolete address
information, ...) which makes automatic processing a nightmare.
To make this easier, such license headers in the source files will be replaced
with a single line reference to Unique License Identifiers as defined by the
Linux Foundation's SPDX project [1]. For example, in a source file the full
"GPL v2.0 or later" header text will be replaced by a single line:
SPDX-License-Identifier: GPL-2.0+
Ideally, the license terms of all files in the source tree should be defined by
such License Identifiers; in no case a file can contain more than one such
License Identifier list.
If a "SPDX-License-Identifier:" line references more than one Unique License
Identifier, then this means that the respective file can be used under the
terms of either of these licenses, i. e. with
SPDX-License-Identifier: GPL-2.0+ BSD-3-Clause
you can chose between GPL-2.0+ and BSD-3-Clause licensing.
We use the SPDX Unique License Identifiers here; these are available
at [2].
