Set of executable files for sending and receiving data / short multimedia files through a narrow bandwidth transmission media. The signal output to the transmitter is the sound card analog output socket while the received signal taken from the receiver is fed to a sound card analog input line.
Targeted audience:
* Short wave / long wave (narrow bandwidth) Amateur Radio enthusiasts
* Experimenters of vintage transmission systems
* People living in areas with absolutely no Internet and no 3G/4G/Edge access (only analog telephone or CB radio), so that peer-to-peer data sharing (or even broadcast to several peers at a time) are made possible.
* Conditions where only a unidirectional audio link is available (no handshaking required)
Features
- Narrow bandwidth data transmission
- Versatile unidirectional soft-modem
- Run even on very old distros
