I stumbled across a video from the fabulous Mr Carlson’s Lab YouTube channel. If you haven’t check out this channel before, and you are really eager to learn more about electronics, this is a wonderful YouTube site.
So, in the latest episode, Mr Carlson takes us on a tour of a very large Gates BC-250-GY broadcast transmitter from the 40’s era. Lots of big tubes, transformers and capacitors! This is an old mediumwave transmitter that he has restored. Although the technology has changed markedly since the 1940s, the basic principals of transmission are still present. And, interestingly, he points out that this particular unit was in regular service right up until as recently as 2003!
It’s an interesting show and even if you can’t grab onto all the technical information presented, I think you will enjoy looking at technology from a past era.
73 and good DX to you all,
