Origins of the 405 line system.

Hi.
I just wonder how 243i would look? Today I gave the TV22 a tweek and have been watching 240p on it, the flicker is really bad, instant headache  
To be fair on a 9 inch screen other than the flicker it's actually not too bad.
I've done a YouTube video but the shutter speed is too slow to resolve the flicker, I've posted it though for anyone to see.
It's test card F but I can upload another video with programme material if anyone wants to see it.

This set should have been used for last nights broadcast don't you think!!!!!

Thanks Trevor for the demo 240 lines looks a lot better that I imagined.
Just a thought on the flicker, was the phosphor on the early tubes any different to reduce the flicker?
