Multiplatform Soundcard Packet Radio Modem

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 Windows version runs on Windows platforms supporting DirectSound and requires PC/FlexNet32. To install the software, just unpack the archive into the same directory as FlexNet32.

The software is published under the GNU GPL V2
