was due for completion in late 1959 or early 1960, but various slight delays over equipment, delivery, weather on site and so on held the programme up and although the project was not yet complete at the end of the year, work was by then well in hand and the target date of June 1st had been set for the official opening of the services. The aerial mast, a 100-foot high lattice column supported by a 35-foot steel lattice tower, was already a prominent, but not unsightly feature of the Peak landscape at the end of the year, and as the photograph at the frontispiece shows, the site commands a magnificent view of Hong Kong and Kowloon.

122. Both services will normally be run in parallel with their medium wave counterparts but for special programmes the VHF and MW transmissions will separate.
123. Provision has been made for carrying out stereo broadcasting tests, with MW as one channel and VHF/FM as the other, at a later date.
124. The alterations to accommodation in the studio centre men- tioned elsewhere necessitated a considerable amount of rewiring of programme ringmain circuits on the 6th and 7th floors of Mercury House and this work was principally complete by the end of the year.
125. The echo chamber located in the basement of the General Post Office was still in use by the end of the year, although it was about to be replaced by an electromagnetic reverberation device located in Mercury House, equipment which is used with great success by the BBC and which will provide a much wider range of artificial acoustic effects.
126. Correspondents of other broadcasting organizations were again provided with studio facilities for the transmission of despatches either by means of recordings or the Cable and Wireless radiotelephone circuits.
