Re: BT 'Chiltern' telecom towers
Yes, I included a link to Richard Lamont's website in post #7. That's wire-tapping the hard way.

Re: BT 'Chiltern' telecom towers
I remember spending quite a bit of time near the Stokenchurch tower back in the late-1980s when they were releasing Red Kites as part of the reintroduction program. Now, the Kites are *everywhere*.

Re: BT 'Chiltern' telecom towers
As daft as it sounds, the Tinshill tower appeared to have different 'faces', depending on whereabouts you were looking at it from. I suppose it was the mix of dish and horn antennae at different levels that gave these appearances (to a juvenile me, anyway). It could look benign, cheerful, disapproving and very scowly! Nowadays it has one face for all occasions: blank.

Re: BT 'Chiltern' telecom towers
Here's a scan of the slide I took, from a moving coach, at Easter 1965, with only a couple of horns visible.

Re: BT 'Chiltern' telecom towers
Up for sale at some point eh?
Would suit very keen radio amateur. Imagine trying to get planning permission for one like that. And if you promise to keep secret what you will use it for, there is no change of use! David

Yep, that sounds about right - you will find that CND members are usually very nice people and excellent friendly company

Re: BT 'Chiltern' telecom towers
They should have figured out that the military facility would be separate to the BT one. Did they think the military could afford BT's prices?

Re: BT 'Chiltern' telecom towers
Going back all the way to "Manchester" Rambo and Paul Sherwin [at posts 21/22] I was having computer text problems then so didn't comment. As a teenager, I used to spend a lot of time in Heaton Park but not always on a technical basis, they had a Fairground and girls etc. The tower went up without too much reaction or excitement but it did have an aura of mystery. Anyone interested, ie not many, accepted the TV comms explanation without comment. We only went close on one day and a chap advised us to maintain our distance, which we did.
Two friends of mine were keeping ancient machinery running at the famous Ramsbottom Soaps Works. They were the only people who could! One of them got a job with the GPO but not me. I couldn't work out the AND /NOR gate questions in the entrance exam. You needed to get 12 out of 20 but I only managed 7 [by guess work]. I did get a job as a clerk at Post Offices Supplies in Cheetham Hill though [now a Transport Museum]. My successful friend worked at the PO tower and I stayed with him in Ealing, circa 1968, when sent to London on the standard GPO staff introductory course. He told me that he was working on the very top level of the GPO Tower with the Transmission Horns and that young males, in particular, were advised to not stand in front of the waveguides if they had any ambition to procreate in the future He seemed fairly convinced that it was a National Defence Project designed to use direct micro wave links instead of Land Lines in the event of an attack. The "spinal" nature of these towers seemed to point in the same direction. Later I had a clerical job in central Manchester. The GPO exchange nearby was reputed to go several stories underground and to be a part of the same set up. Manchester is actually very built up geographically and riddled with underground passageways. Just check out the area by the river near Victoria Station. Going on from that, I subsequently had relatives in Stokenchurch and saw the same sort of link. Some of these towers seemed to pop up in very unexpected places back then!

Re: BT 'Chiltern' telecom towers
That made for a good read. The mast at Hunter's Stones looks very bare today compared to the picture in the article. Still quite an imposing sight.

Re: BT 'Chiltern' telecom towers
Thanks for the Subterranea link Steve. I've got the Peter Laurie book! Typing Secret Underground Manchester now goes to the Manchester Evening News site which reveals more about the Telephone Exchange System and back up plus the long history underground, including the area along the river. It also mentions the "long forgotten" [not by me] scheme to have an Underground of a different kind ie a Tube System similar to "that London". I wrote to the MEN in 1972 pointing out that, in a war time situation, the Army could lay half a mile of track through the then derelict Castlefield Area if a link between Piccadilly and Victoria Stations was urgently needed.
That's been done recently to provide a direct rail link between North and South as well but it's overcrowded already On the theme of secrecy re the Microwave Tower chain, the Post Office Exchanges and more generally, I knew and wasn't surprised that the Tube for Manchester idea was rejected in terms of cost and practicality. I'd no idea at all that they actually made a start in Piccadilly Gardens though I was working there then in the Sunley Buildings Tower Block across from the BBC Manchester [pre Oxford Road] building. Quickly abandoned the project was intended to be constructed between 1973 and 1977. Optomistic at best I'd say. There are two books by Keith Warrender on Underground Manchester [mentioned on the MEN site] I'd recommend. He used to give guided tours! Dave W I once helped a widow dispose of a very big lattice type mast that had supported a Triple Short Wave Array and other items. Not Emley Moor size but massive all the same [he owned a piece of land at the side of his house so the structure and guys etc could be accommodated. I remembered seeing it as a school boy [hard to miss really]. Taking it all down was along the lines of getting one of those dangerous springs in tension out of a wind up Gramophone without serious injury to all and sundry. They got it on a low loader, used a welding torch to remove the base mounts and drove away. Apparently the chap's wife took one look and said "Not with your heart condition" so it went elsewhere after all that! Last edited by dave walsh; 13th Jun 2020 at 11:19 am. |

Re: BT 'Chiltern' telecom towers
Just to be clear, only the tinfoil hat brigade would claim that the microwave network was built exclusively for military use, with phone traffic and TV distribution as some sort of bogus cover story. It was a multipurpose system from the very start - it was obvious that the military would only need a fraction of the capacity of this very expensive system in peacetime.
Nevertheless, the military aspects were important, and most of the towers were hardened against blast. When they were being designed in the 50s there was a very real fear of all out nuclear war using Hiroshima sized warheads delivered by manned bombers. The towers (including the London one) were designed to stay standing after such an exchange, though they wouldn't be functional without significant repairs. Nevertheless, it was hoped that a national communications backbone could be re-established in weeks rather than years. The towers would not survive an attack with large thermonuclear warheads of course, so this aspect was becoming redundant even as the towers entered service. |

Re: BT 'Chiltern' telecom towers
Here're a couple of pics showing the SHF furniture of the mid-'80s. Charwelton SHF tower near Daventry (the concrete tower) and Cambret Hill BT 'climbing frame', next to the BBC / IBA UHF TV relay site. Cambret Hill was aligned with a similar erection on the English side of the Solway, at Wharrels Hill, above Bothel.
When I passed Wharrels Hill recently, there were two, maybe three dishes less than 1m diameter on there. Haven't been near Daventry or Cambret Hill for years.

I know that the TV aerials serving the Piccadilly Hotel were on the roof of Sunley House, and there is a veritable farm of aerials up there today, including a local DAB station. About the same time there was a radar head (weather?) on top of the CIS building, (The tallest point in the city until 2006), you could just about see it rotating from ground level. That's spooky, Mr Google does not seem to know about this radar, I'm sure I didn't imagine it!

Re: BT 'Chiltern' telecom towers
No you couldn't get up to the roof. I was on the 22nd floor [of 28]. We did have regular fire alerts [usually a painters blowlamp] and were top priority with the London Road Fire Station just nearby, as you will know and now a vintage item in itself I recall coming back with a sandwich to find fire engines parked round the back of Sunley, near the modest entrance to the "Deep" Telephone Exchange and the Shift Commander reporting in "two minutes and 23 seconds!", somewhat triumphantly. The Piccadilly Hotel Sign was a very large structure on top of the their building [itself only about five Storeys I think]. We looked out of our windows during a major storm one day to see the sign, far below, waving about like a flag and due to crash down through the Atrium Roof. After we alerted the management, the London Road crew turned out with ropes to secure things. "High" drama, you could say.
