Telephone On-The-Air Unit
72. This unit was designed and produced for listeners to telephone Radio Hong Kong for programmes such as 'Late Call' and 'Telephone Quiz'. It changes a telephone from a two-wire into a four-wire system.
Experimental Stereo Broadcasts
73. A stereo broadcast was set up experimentally in June 1969 using the pilot tone system. The transmitting site was in Broadcasting House using two 3-element Yagi aerials directed at Sheung Wan and North Point. They were driven by a 40 watt-VHF power amplifier with 4 wave length matching network. Field strength coverage was good and a minimum of 200 uV/M could be obtained within the built-up areas of Kowloon and Hong Kong.
