"Throwback: Hilarious Ham Radio Memes from the 1970s"
A video showcases a Robot slow scan receiver from the 1970s, which was used by ham radio operators for sending pictures via low-bandwidth audio. SSTV-equipped hams would exchange memes and selfies on specific frequencies, but there wasn't much conversation. Nowadays, PC soundcards are commonly used for SSTV, but back then, the Robot with its 6-inch screen and $295 price tag was considered advanced. The machine still works well and serves as a reminder of vintage ham radio gear.
