FS1000A and XY-MK-5V 433MHz #Arduino radio modules range test

Subscribe to Hacker University newsletter https://bit.ly/3I3qnAJ FS100A and XY-MK-5V are super cheap and super simple 433MHz modules. Some people report they work well, some that link is lost even at a range of few centimeters. I've decided to test that, and do a proper range test in open space. With proper antennas, those little 433MHz modules can have a decent range. Who would expect that...
