Audio Sample

FreeDV plus Video (also known as FreeDV+) combines analog FMFrequency Modulation multicarrier Narrow Band TV (NBTV) by Con Wassilieff, ZL2AFP, and FreeDV digital voice by David Rowe, VK5DGR. Bandwidth is 3.5 kHzKiloHertz (kHz) 10^3 Hz, frame rate is 0.9 FPS, with 36-line resolution, full color. The ZL2AFP software has been modified for compatibility with the FreeDV "700D" and "1600" modes. FreeDV+ requires transmitting with a low-IMD transceiver and external amplifier, using Class-A and/or adaptive predistortion. FreeDV+ combines the NBTV and FreeDV signals using Frequency Division Multiple Access (FDMAFrequency Division Multiple Access), a technique also used to combine signals in communication satellites.
