      Hi Romeo,

      Thanks for the question – this is a tough one.
      One of my favourite examples was in my job last year, where I had to basically build a large anechoic test chamber. Anechoic chambers allow you to test radio waves in a special environment with spiky foam lining the walls so you don’t get any reflections etc. It was a great system with lots of moving parts and it looked liked something out of Star Trek.

      Anyhoo, my problem was to get the system working again at our new office in London after it had been dismantled and moved. We had a weird result in all the measurements, a curious spike was seen on all the graphs at the same point each time. After doing alot of thinking and playing around with the system, I discovered it was a problem with an expensive RF cable which had become damaged by being bent around a very tight angle. So I ordered some new ones (£2000 each) and replaced it. It took me 3 days to install the new cables and now the system works great.

      Hope that answers your question! Please feel free to send me more.

      Kind Regards,
      Dipendra
