Default Explosion at Caradon Hill Mast around 1970?

Not wanting to drag the Bilsdale thread off course.

The Caradon Transmitting mast had its shares of trauma back in the day.

It got hit by a RAF jet (only the a stay ) but ISTR it was off for sometime.

The Jet crashed but fortunately the pilot was unhurt.

I visited the station a few times around 1972 to 1975 thanks a neighbour being an engineer at the site.

There was I remember a display case with a piece of torn feeder like the case of a big banger. Memory suggests the feeder was around 100mm in diameter and it failed on the bend where it turned 90 to go up the mast

I think he said that the feeder was kept under positive pressure but that water had got in and when there was just the right amount the water boiled and blew out the feeder.

Now this is all 45+ years ago.

Anyone else remember these events?

Cheers

Mike T

I certainly remember Westward Ch.12 being on reduced power following a major storm.
The difference in strength between Ch.12 and Ch.1 (BBC1 Redruth) meant that you
did need to adjust the contrast control. I made a crystal set for Ch.1 which worked.
The incident you relate to is this one;

The Winter Hill plaque is on the side of one of the buildings, easy to read from tbe road side. As an aside , directly opposite is Scotsman’s Stump, erected in memory of George Henderson who as murdered on Rivington Moor in 1838.

I do remember this Caradon Hill incident. I was only young and living on the east coast of the Lizard peninsular at the time. All of the Caradon Hill TV channels went off and caused a TV blackout for a few hours or so across Cornwall, West Devon and parts of North and South Devon.
All three 625 line channels from the Redruth transmitter also went off as the Redruth programme feed was a direct pick up from Caradon Hill. BBC1 405 from Redruth on ch1 also went off for a short time as they used a 625 to 405 line convertor and I think it switched back to the original 405 feed from North Hessary Tor on ch2.
On 405 we lost Westward TV on ch12 and on 625 we lost BBC1 on ch22, BBC2 on ch28 and ITV on ch25.The only station we had that evening was BBC1 405 on ch2 from North Hessary Tor which meant I had to move my 17" Cossor Premiur 405 line TV from my bedroom to the lounge for the evening.
