RXSSTV is a lightweight, no-frills slow-scan television decoder developed by Belgian radio amateur ON6MU, expressly designed for hobbyists who want to acquire SSTV images from passing ISS events, weather-balloon transmissions, or local ham QSOs without navigating complex menus. The 2.2.0 release refines the original 1.x branch with tighter AFC tracking, automatic slant correction, and a resizable waterfall that still keeps the “back-to-basics” philosophy intact; both major versions remain on offer so legacy systems can stay with the earlier engine while newer PCs benefit from the current codebase’s lower CPU footprint. Operation is straightforward: the program listens to the sound-card input, detects the VIS code, and starts decoding the moment the first sync burst arrives, saving finished pictures as BMP or JPG in a user-chosen folder. Because it only needs a 44.1 kHz audio stream, any inexpensive SDR dongle, handheld scanner, or even an old HF rig patched to the mic socket is enough to turn a laptop into a portable SSTV monitor, making the utility popular among field-day operators, satellite spotters, and emergency-training groups who value software that loads instantly from a USB stick. RXSSTV is classified under Communications / Ham Radio and is available for free on get.nero.com, where downloads are provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
