Radio City, owned and operated by the then Emap Radio, expressed interest in refurbishing the tower to house Radio City and Magic 1548, including their studios and required office space. The plan was announced to the public and in the interim period, Radio City would regularly broadcast from the beacon and also broadcast during the Lightshow Festival period in late 1999 which involved many different patterned and coloured lights being shone from the tower. Work commenced in 1999 and was completed in the summer of 2000. Radio City Tower (1999-present) The tower was refurbished in 1999 at a cost of £5 million. It reopened as Radio City 96.7 (and Magic 1548) in August 2000. The outdoor observation deck, which had been located on the roof of the restaurant, was transformed into a second floor. It now holds offices and conference rooms, for both radio stations. The studios are on the lower floor, which was previously the restaurant. The original revolving structure and machinery were left intact during the refurbishment. Brackets were added to lock the moving structure in place. The tower has been known to sway in heavy winds. This is a design feature and common in construction within skyscrapers and tall building in order to prevent the building snapping at its base or cracking along the shaft. During the refurbishment between the 1st and 2nd floor, the Radio City 96.7 lettering was added. It is illuminated in yellow, during dark. Several other lights were added onto the base of the crows nest structure, which is illuminated all day and periodically change colour. During Christmas, a beam of light is fired onto the base of the tower, with a Christmas themed image displayed. The 2nd floor windows are illuminated at night, sometimes with a particular colour to mark certain events. A red aircraft warning beacon sits on top of the tower's main structure. The refurbishment added an advertising framework at the top of the tower, designed for both a fabric banner and illuminated light boxes. Window cleaning and light bulb changes are performed by specialist teams, who abseil down the side of the tower. The roof houses the local 10C Digital Audio Broadcasting multiplex for Liverpool. Radio City and Greatest Hits Radio North West do not directly broadcast from the roof. Their FM signal is transmitted by the Allerton Park Transmitter, along with BBC Radio Merseyside on 95.8FM and Capital
