Studios
DIDSBURY STUDIO CENTRE, Manchester (Didsbury 8181). Winter Hill and Emley Moor transmitters receive their weekend programmes via the ABC master control rooms at Didsbury. Here too is based the Outside Broadcast fleet. The main studio has a stage area of 5,000 sq. ft. and has seating for an audience of 600. The second studio has an area of approximately 1,000 sq. ft., and there is a presentation studio attached to the dual master control rooms, plus an announcer’s booth for sound only.
BIRMINGHAM. Alpha Television Studios, Aston, Birmingham (Aston Cross 3091), are jointly owned by ABC and Associated TeleVision Limited. There are three studios of 3,000, 1,200 and 380 sq. ft., and master control and technical areas which were housed in a new building during 1962.
TEDDINGTON STUDIO CENTRE, Broom Road, Teddington (Teddington Lock 3252). This modern studio centre has been established close to London, where the main body of artistes is available. It specialises in the recording of drama, light entertainment and feature programmes. Studio 1 has an area of 7,500 sq. ft.; Studio 2, 4,750 sq. ft.; and Studio 3, 2,500 sq. ft. The technical equipment covers an area of 8,000 sq. ft. and is fully multi-standard with immediate switching between 405, 525 and 625 line standards. The new central block, opened in 1962, has in addition 13,000 sq. ft. of rehearsal rooms, an acoustically treated recording studio of 1,700 sq. ft., and scenery assembly and handling facilities.
Outside Broadcast Units
ABC have three Outside Broadcast units based at Didsbury, all with 4½” cameras and a smaller vidicon unit. In addition, the mobile videotape recorder can be equipped with one or two cameras, there being a total of twelve available between the units, There are seven microwave link units with portable power generators, and a hydraulic platform tower truck.
Videotape Recording
There are two machines based at Didsbury, together with the mobile unit. At Teddington there are four standards-switchable transistorised recorders together with standards converter equipment. At Alpha Studios, Birmingham, there are two machines.
Colour Television
One of the flying spot telecine channels at Teddington is equipped for the generation of colour signals, and programmes from Teddington have been experimentally radiated by the Croydon transmitter. In addition, numerous public demonstrations have been given over the GPO network, notably those using the continental SECAM system.
Technical Developments
A considerable amount of apparatus was specially developed for the Teddington Studio Centre in order to achieve full multi-standard operation. All this newly developed equipment is transistorised, and, in particular, vision switching matrices and pulse and vision distribution amplifiers have been used in considerable numbers.

The first proposal for covering the great Northern area with its population of about thirteen million was to build a high-power transmitting station close to the existing BBC Band I station at Holme Moss on the high central rib of the Pennine Chain. Studies showed that this would have been technically attractive had it been possible at that time, without a very considerable delay for special development, to provide an effective radiated power of about 500 kW with a mast height of at least 1,000 ft. Even so, severe fading would undoubtedly have been experienced at the fringes of the service area, on the west coast at Liverpool and on the east coast at Hull.
These and other considerations led the Authority to conclude that the area would be served best by two transmitting stations, one on the western slopes of the Pennines to serve Lancashire, Cheshire and parts of Staffordshire, and another on the east side of the Pennines to serve Yorkshire. The Postmaster-General agreed to this proposal, which constituted the first of several departures from the general principle that Band III stations should be sited close to existing Band I stations. The quality of service which has been given to the North of England as a result of this departure has fully justified the decision. Winter Hill, the Lancashire station, was constructed on the summit of Rivington Moor, a fine site 1,450 feet above sea level. The aerial, which is carried on a self-supporting 450 ft. tower radiates 100 kW omnidirectionadly. Construction work began in September 1955 and the station went into programme service on 3rd May 1956.
Winter Hill
The selection of the site for the Yorkshire station posed considerable problems largely because coverage of the main concentration of population within the hill-shadowed towns of the West Riding had to be combined with the provision of a service as far away as Kingston-upon-Hull some 5o miles away across the Yorkshire Plain.
Sixteen different sites were studied theoretically and tests, using a balloon transmitter, were made at four of them before Emley Moor, 850 feet above sea level on the eastern slopes of the Pennine Chain, was finally selected. Once again, because of the small area available, a 450 ft. tower was used to support the aerial, which has a semicircular power-radiation pattern delivering 200 kW e.r.p. in all easterly directions but only a few kilowatts backwards to the west into the natural barrier of the Pennines, thus preventing waste and an unnecessary overlap with the service area of the Winter Hill station. Emley Moor went into service on 3rd November 1956.
Geographically, the siting of a station to serve the industrial Midlands proved fairly straightforward, because the service area of the BBC’s Band I station at Sutton Coldfield corresponded closely with that which the Authority also wished to achieve. High open ground in the area is scarce and, with reason, carefully protected. It was not therefore easy to find an acceptable site. A piece of land 500 ft. above sea level, about four miles north-east of the BBC station, was eventually secured. It lies near the Watling Street in the rural district of Lichfield, from which the station derives its name.
Initially, an available design of 450 ft. self-supporting steel tower was erected, carrying an omnidirectional aerial similar to the one used at Croydon but of twice the aperture. This enabled a service to be provided quickly. The station went into programme service on 17th February 1956 with a single 5 kW transmitter, giving an effective radiated power of 6o kW. A few months later the power was raised to 120 kW by paralleling two 5 kW sets into the split aerial. In November of the same year, after the main 20 kW transmitter had been installed, the power was raised to 200 kW e.r.p. This gave a population coverage of nearly 6.5 million within the o.25 mV/m contouur. From the start it was recognised that, because of the relatively low site, greater and more uniform coverage could be obtained with a higher mast and an aerial system with directional characteristics. Sufficient land was therefore acquired to permit this to be done later.
Early in 1961 it became possible to start the construction of a 1,000 ft. mast and an improved aerial. Both these were brought into service in July of the same year, thus allowing the original tower to be dismantled and re-erected for use at the Fremont Point station in the Channel Islands. The new aerial enabled the power radiated south towards Gloucester to be increased to 400 kW.
Towards East Anglia, however, the power had to be reduced to 100 kW to prevent harmful interference to viewers of the Netherlands Television Service on the Dutch coast. For this reason, the service to Midlands viewers living east of the station remained substantially unchanged. Over a semi-circle towards the north the radiated power was maintained at 200 kW. This was sufficient, with the higher aerial, to close the gaps between the service areas of Lichfield and the Winter Hill and Emley Moor stations. The effect of the new mast and aerial was a general all-round improvement in reception, both within the old service area and beyond. The predicted coverage is shown in the map opposite. The measured coverage has recently been completed and includes a population of 8.85 million within the 0.25 mV/m contour.
