SSTV - Slow Scan Television


Slow scan televison is a way of sending video over a voice bandwidth channel--this can make it practical to send video over thousands of miles via ionospheric propagation.  Modern computers make this once rare and expensive mode readily available to the average ham. Other ways to work with images over radio are discussed on the Image Modes page.
