Slow-scan television (SSTV) is a picture transmission method, used mainly by amateur radio operators, to transmit and receive static pictures via radio in monochrome or color.

I was just messing around with the programs and threw in some RGB satellite imagery and it came out like it was some picture from a 1960s satellite

you could code a modulation system in python, simulate noise, then demodulate the result to get a sstv simulator
