FreeDV is a GUI application for Windows and Linux (MacOS and BSD are
|
|
in testing) that allows any SSB radio to be used for low bit rate
|
|
digital voice.
|
|
|
|
Speech is compressed down to 1400 bit/s then modulated onto a 1100 Hz
|
|
wide QPSK signal which is sent to the Mic input of a SSB radio. On
|
|
receive, the signal is received by the SSB radio, then demodulated and
|
|
decoded by FreeDV.
|
|
|
|
FreeDV was built by an international team of Radio Amateurs working
|
|
together on coding, design, user interface and testing. FreeDV is open
|
|
source software, released under the GNU Public License version
|
|
2.1. The FDMDV modem and Codec 2 Speech codec used in FreeDV are also
|
|
open source.
