Slow Scan Television (SSTV) is a fascinating mode that allows you to send and receive still images over HF radio using your SSB transceiver. The uBITX and similar homebrew/commercial SSB radios are excellent platforms for SSTV operation. This comprehensive guide will walk you through the complete setup process.
Slow Scan Television is a method of transmitting still images over radio using audio frequency tones. The term “slow scan” distinguishes it from conventional fast-scan television (like broadcast TV), which requires much wider bandwidth.
