Re: Briantist
The page looks good, thank you.

My Granddad made the first colour TV.
He had a black and green cathode-ray tube from an old radar display at the end of the war and used it to make a black and green 405 VHF TV.
They used to show fish in a fish bowl between programs, so the fish looked better in black and green than black and white.

Mark Agius: No problem.

I used to have an amber-screen monitor that connected to a VHS machine (for the tuner) via a long length of cable as to a monitor in the kitchen. The picture quality (as it was unmodulated) was excellent as I recall.

The other quite interesting thing about 405 line TV was that the line frequency was 10.125 Khz, so even older people with slightly reduced high frequency hearing could hear the line scan whistle very clearly. I well remember tv control galleries from the mid 1960 with about 20 or so 405 line monitors all screaming out the line scan at 10.125 Khz. Deafening!!

When 625 line came in the line scan frequency rose to 15.625 Khz and most people couldn't hear it.

I notice that in BBC Handbook 1974 that Crystal Palace VHF Band 1,Channel 1 was running at 200Kw.But by the time VHF/TV
Transmitters were being switched off in
1982 erp at C P had been reduced to 100Kw.
I would be interested to know why,when and how this was achieved?
Similarly,the IBA Black Hill,VHF Band 3
Transmitter at various times was running
at 300Kw,475Kw and 400Kw.
