WeatherScan 2.0 - Bringing back UHF SSTV
For any newer hams reading this, SSTV (Slow Scan TeleVision) is an interesting mode in Amateur Radio that converts images to sound files, and the sound is sent over RF. The receiving station has some software that reprints the image line-by-line from the audio file that is received.
