Short-wave Service The installation at Titahi Bay of the two high-frequency transmitters and the first set of aerial arrays was completed during the year, and temporary studio accommodation has been arranged in the city. The aerial arrays which were installed will direct transmissions in a north-westerly direction, and a second set to transmit in a north-easterly direction is planned, but progress is held up owing to difficulties in getting suitable steel masts. This second set will improve the service which can be given to the Island Territories in the Pacific. Test programmes were radiated nightly for one week during November, and reception reports were obtained from many countries. Reports from Australia, India, Malaya, Japan, and the Pacific Islands were most gratifying and show that a useful service can be provided to these areas. It is expected that the regular service will commence later this year.

Stations in Operation The following stations were in operation during the year :

Hours of Transmission The aggregate programme transmission time of all stations, both National and Commercial, amounted during the year to 72,438 hours. Of the scheduled programme time, 20 hours were lost due to technical defects in equipment and 28 hours due to failures of the mains power-supply. This does not include time lost through shut-downs for the purpose of electricity-conservation.
