Radio woes hit public services
More than 1,000 complaints of radio interference involving government services were investigated in the first 11 months of last year - 40 per cent of the total complaints, figures from the telecommunications watchdog have revealed.
The Office of the Telecommunications Authority also investigated 1,078 cases involving broadcasting services and 324 in the commercial sector, making a total of 2,443 complaints during the period.
A yearly figure of about 3,000 complaints, the average over the past 10 years, was cited by the government on Friday in the Court of First Instance hearing into an injunction against Citizens' Radio. Although none of the complaints involved Citizens' Radio, the government said unlicensed broadcasts would encourage more illegal broadcasters, increasing the risk of radio interference.
Wat Ki-on, chairman of the Hong Kong Fire Services Ambulancemen's Union, said he had never heard of any complaints of radio interference.
A Civil Aviation Department spokesman said the department did not keep records on radio interference.
City University professor Edward Yung Kai-ning said: 'Even a disruption of a conversation on a mobile phone is a kind of radio interference.' He added that all electronic devices would create harmonics, which could disturb other frequencies.
