Slow Scan Television (SSTV) is a method of transmitting still images over radio frequencies. It was first developed in the 1950s and has since become a popular mode of communication among amateur radio enthusiasts. Unlike traditional television, which uses a continuous stream of images to create a moving picture, SSTV transmits individual still images, which are then displayed sequentially on a receiver's screen.

SSTV works by transmitting an audio signal that encodes an image. The audio signal is modulated onto a carrier wave and transmitted over a radio frequency. The receiver demodulates the signal and converts it back into an image. The image is then displayed on the receiver's screen. Because the images are transmitted one at a time, SSTV is a relatively slow method of communication, with each image taking several seconds to transmit and display.

SSTV has a variety of applications, including amateur radio, space exploration, and military operations. Amateur radio operators often use SSTV to send images of their equipment, antennas, and operating locations to other operators around the world. SSTV has also been used to transmit images from space probes, such as the Mars Reconnaissance Orbiter and the Voyager spacecraft. In military applications, SSTV has been used to transmit reconnaissance images from unmanned aerial vehicles (UAVs) and other surveillance platforms.

To use SSTV in amateur radio, operators need a few pieces of specialized equipment. First, they need a transceiver that can transmit and receive on the frequency bands used for SSTV. Second, they need a computer or other device that can generate SSTV signals and interface with the transceiver. Finally, they need an antenna that is suitable for the frequency band they are operating on. Some operators also use specialized software or hardware to enhance their SSTV signals and improve the quality of the transmitted images.

SSTV is often used in amateur radio contests and events, where operators compete to transmit the highest quality images over a given period of time. Contests may involve sending a specific image, such as a logo or a photograph, or transmitting as many images as possible within a set time limit. In addition to contests, amateur radio operators also use SSTV for special events, such as commemorative transmissions or broadcasts from rare locations. These events provide an opportunity for operators to showcase their equipment and skills, as well as to connect with other operators around the world.

Station Master Desktop is compatible with MMSSTV, make sure you install it in the default location.
