Group hopes to penetrate mainland's firewall with live radio broadcast of June 4 vigil

Will mainland residents be able to bypass internet censorship to watch a live broadcast of tomorrow's candlelight vigil commemorating the 1989 crackdown on the pro-democracy movement?

That's the question facing radio activist Yang Kuang, who is leading a group of Hongkongers in an attempt to broadcast the vigil in Victoria Park live to the mainland.

A similar attempt last year by Green Radio was unsuccessful, but Yang said he was confident.

'Last year, we saw a lot of mainland people attending the vigil,' Yang, 43, said. 'We believe many who can't come to Hong Kong hope to see the event, and therefore we'll do our best to provide technological help.'

Yang, a host of Green Radio, said people on the mainland could access the online radio's website for tomorrow night's broadcast.

On June 4 last year, he said, the broadcast relied on a single server, which mainland authorities quickly identified and blocked.
