Due credit was given to the Baird system with its Heath Robinson machinery. By comparison the M-EMI system was rather dull. No moving parts, it just worked. That isn't strictly true, there were any number of problems from tilt/bend adjustments to supplying enough working Emitron tubes.
This was rather reflected in the programme. The M-EMI side relied on Paul Marshall's reconstructed CPS Emitron camera which is the nearest we're likely to get to a working pre-war one. It just worked. Hardly exciting for the average viewer compared to whirring machnery.
My own work on the programme was rather frustrating. First they could have had my pre-war 702 instead of a 1950s vintage TV22. The producers also insisted on having a radio link to the receiver rather than running closed circuit. I never found what the problem was in that building but it just seemed to soak up Channel 1 RF, making it very hard to get a decent picture on the TV22. I had help from Danielle George who was presenting part of the show but she's also a first rate RF engineer. She had kindly brought a handheld spectrum analyser with her and we worked together to try and find what was going on. I should have faked it, run a cable and not owned up to it.
As I've said in some previous posts, making the programme was good fun at times, but very annoying at others.
