- FTV is an MS-DOS program used to receive images from Weather Satellites and Terrestrial Facsimile Stations, text transmissions from rad
io telex services, Morse code, as well as Amateur Rad
io FAX, SSTV, RTTY and CW signals. It can also be used to transmit FAX and SSTV. No external hardware, other than a rad
io, is required, as all the necessary signal processing is implemented in software.
