This is some pretty cool old school technology. This technique was used in the 1930's to send a photograph using radio waves. Not really sure why they made it so complicated. It would have been a lot easier just to send the picture in a text message lol. Seriously though, this was probably the best technology that they had and we had to go through that to get to where we are today. They were technological pioneers who paved the road to Silicon Valley.
