I am the woman in the video, I am a technician in the engineering team. It was my job that night to walk Tony through the process of turning off the transmitter, to be on hand if problems arose and to ensure that transmitters were safely off and isolated. Lichfield is still used for a few services just not TV. It's possible to switch each transmitter off with one switch but it's safer to power down in stages and also this gives multiple isolation points to lock off the transmitter to stop it be
CH5 at Lichfield was actually a parrallel transmitter, A & B. This was the normal configuration of most CH5 Main transmitters. In normal operation both would be running to give full power but in a fault situation or for planned maintenance the service could be sustained with 1 transmitter, therefore on reduced power. So in the case of this shutdown it went from full power, to reduced power and then off.
HD was transmitted from this site for freeview, it was switched off at the same time as channel 5 analogue. The HD is now broadcast from Sutton Coldfield.
Channel 5 had 2 Analogue Transmitters. The main and backup, so when the first was switched off the output would have been low power. Channel 5 did not go off until the second transmitter had been switched off, then the power supplies for each and finally the Isolator where switched off.
Greetings from the USA: I spent 15 years working on two different Harris Sigma IOT transmitters: a 3 tube analog (US channel 17) and a 3 tube ATSC 1.0 rig (US channel 45). What are the two "boxes" immediately to the left of the IOT cabinet? Line control cabinets? In the US we used beam supplies mounted outside, and a "line control cabinet" mounted to a wall (in the TX room), which interfaces the TX to the beam supplies @ 480 VAC 3 phase. I'm pretty certain those LCCs were US made; the beam supplies were also made in the US by a third party supplier (NWL in New Jersey).
Great video - one thing it doesn't show is how and where the signal comes into the site for the signal to be transmitted. Does it come in by cable or is it relayed from another site/satellite?
It is sad that the Lichfield Transmitter won't be used for TV again. I know that after 1985 the transmitter wasn't used for TV for some years because of the 405 Line switch off and didn't get used again until Channel 5 began,
That is correct, all TV for that region is now transmitter from Sutton Coldfield. However I expect the mast will remain for other uses such as FM and DAB use.
There seemed to be an awful lot of switches to turn off. I'd have thought it would be just one for the C5 analogue transmitter and one for the HD mux transmitter.
The Dishwasher I wish I still had analogue today. If I switch to analogue, there are 100 channels (00-99) all I get on every single channel is a black screen.

Very sad to see the top quality Analogue go off air
@@devonguy02 yup
They didn't trust a woman to do it herself?
To stop it be... what?
Can you turn analogue back on 🥺
Great video, Gerald! Glad you had the thought to drive up there - you've captured something unique!

Nice piece of Television history recorded for all generations to see.
People in 100 years time will be fascinated by this old technology.

R.I.P Analog tv, birth of Digital tv

Pye designed and installed the original Band 3 transmitters in 1955 bring ITV to the Midlands. Happy days

Thanks for the info tvjockey
After analog tv shut down what has became of that transmitter?
Also BBC One, BBC Two, ITV1 and Channel 4 (not only Channel 5)
Those transmitters look fairly new did they sell them I would of left fans on longer to cool then is with out damage
There seemed to be an awful lot of switches to turn off. I'd have thought it would be just one for the C5 analogue transmitter and one for the HD mux transmitter.
It should've not been shut off, now I can't pick up a single channel!!!
This was 2011 buy a new tv
@@GTR567 Rude.
@@VrantusOfficial im right tho
Why they switched off analog TV worldwide? Iam sure this is not only for the quality. Maybe the radiation was bigger? Other reasons?
Who is the bloke doing the switching off? Somehow, he just doesn't seem like an 'engineering' type.
He is an engineer at Arqiva.
Somehow?
Why would I like this video. I only disliked this video because it was very sad to see a analog transmitter being turned off.

@@SB-gw7cc most of the channels were placeholders
Should just have tripped the MI and blacked the whole site 😂
A colleague of mine and amember of Arqiva staff working out of Sutton Coldfield
R.I.P.
Don't forget the B side please 🤣
I Love Radio 😭
bet the pratt couldn't stir his own tea
So sad
Was BBC HD ever analogue?
No, no way of transmitting HD on analogue.
Stop analog broadcast, and stay on digital broadcast.
