I’m curious about radio technology back in the 1930s. I’m curious about how these American news papers got their information in real time. how well along was radio technology back then? Were they constantly talking to our allies overseas through radio? or am I missing an old tech we had for this? :) I’m a young’un and I just want to understand how they got their information. BTW, thanks for starting these posts. Some of the best history lessons I’ve ever had. It looks like the $*1t is about to hit the fan in Poland.
Shortwave radio was invented by Marconi sometime around 1923. It really took off in 1927 or 1928 though. Shortwave reflect off the ionosphere so it allows for a message to be sent anywhere on the earth despite the fact that it has to traverse the curvature. (i.e. Ham Radio)
we had oceanographic cables.
