Open Source File Sharing Software

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)
