Digital Slow-Scan Television (SSTV) Software
Find applications for encoding, decoding, and managing digital SSTV signals using your soundcard and computer.
Digital Slow-Scan Television (SSTV) allows ham radio operators to transmit and receive still images over the air, often using standard voice bands. Unlike analog SSTV, digital modes offer improved image quality and error correction, making it possible to exchange clear pictures even under challenging propagation conditions. Hams frequently use digital SSTV for casual QSOs, sharing photos of their stations, antennas, or local scenery with other operators around the world.
This category provides various software tools for digital SSTV operation. Operators can find applications like EasyPal and KG-STV that utilize soundcard technology to encode and decode digital SSTV signals, supporting high-definition image transmission. There are also utility programs such as Digi-Ftp and EP Cam that help manage image uploads to web-based galleries or integrate with virtual webcams, enhancing the overall digital SSTV experience for hams.

EasyPal is a sophisticated digital Slow-Scan Television (SSTV) application that utilizes soundcard technology to encode and decode SSTV signals. Developed by the late Erik Sundstrup (VK4AES SK), this software has evolved into a versatile communication tool for amateur radio operators, extending beyond basic image transmission capabilities. EasyPal implements Digital Radio Mondiale (DRM) encoding technology, enabling efficient data transmission over narrow 2.5 KHz channels on both HF and VHF frequencies with remarkable speed. The application supports multiple file formats, including jpg, pdf, txt, doc, and xls, as well as specialized forms such as ICS-213 and ICS-213 (ARES). Additionally, EasyPal offers email functionality through designated repeater stations with internet access. Its responsive development history and robust feature set have established it as a premier digital SSTV solution in the amateur radio community, though users of Windows 11 should note specific configuration requirements to ensure optimal performance.
