I must admit that doing much with the modern electronics is becoming super difficult, but even so when called upon it still takes a broadcast engineer to actually get the whole lot working again. It seems that much equipment is now considered "throw away" when no longer working properly, and it is probably this which has led to the demise of real broadcast engineering. However my spies report that people who have the skills are still highly demanded, there are not very many still being made!
