A Prototype Slow Scan TV (SSTV) System for a High Altitude Balloon Launch (HAB)

Roger KM4LHZ discusses and demonstrate a breadboard prototype of a 2-meter slow-scan TV (SSTV) system (aka narrow-band TV) for a high-altitude balloon (HAB) flight. Pictures are taken at fixed time intervals by a fish-eye Raspberry Pi (RPi) camera and RPi board, and saved to an SD card on the RPi board. A subset of these images are: (1) decimated in size to thumbnail images, (2) inscribed with a call sign, (3) converted to SSTV sound files, and (4) transmitted as narrow-band audio tracks via 2 meter FM. Both necessary and recommended steps for completing a flight-suitable HAB payload package are summarized.
