Talking satellites YO3RAK

I'm sharing videos and personal experience on transmitting and receiving radio-signals from satellites, a very beautiful and challenging area, where the efforts are fully rewarded. There are many satellites for amateur radio traffic, either digital or voice repeaters, or send images of Earth from space. Astronauts from the International Space Station sporadically establish links with radio amateurs and interview students from schools. You can receive all these transmissions, plus there are SSTVs with anniversary occasions, communications between EVA participants and other stuff that occur all the time. Most of the connections are in the VHF / UHF, are made with low power (5-10W are enough) and last very little, maximum 10-15 minutes, because this is what it takes for the satellite to pass over your head. It’s not like the ground connections, where you have enough time, so the preparation beforehand is very important.
