This software allows a standard PC soundcard to be used as a packet radio "modem". The whole processing is done on the main processor CPU.
Unlike previous packet radio modem software, this new release offers several new benefits:
- Now uses standard operating system sound drivers (OSS/Free under Linux, /dev/audio under Solaris and DirectSound under Windows), thus runs on all soundcards for which drivers for the desired operating system are available.
- No fixed relationship between bitrate, sampling rate, and modem parameters. Modems may be parametrized, and multiple modems may even run on the same audio channel!
- Usermode solution allows the use of MMX, VIS, Floating point and other media instruction sets to speed up computation.
- Cross platform builds from a single source code provides ubiquitous availability.
Please note that monitoring commercial services may be prohibited in some countries, this software should therefore only be used to monitor the amateur radio service.
The Linux version integrates with the Kernel AX.25 stack and requires the mkiss driver (included in the standard kernels).
The Sparc Solaris version provides a KISS stream; software AX.25 stacks can interface to this KISS stream
The software is published under the GNU GPL V2
