Tech activists threaten to disrupt Labor's election campaign launch on Sunday A GROUP of self-described "audio rebels" are threatening to sabotage Labor's campaign launch on Sunday in a hi-tech protest against government plans to shut down valuable wireless PA services. Furious at being ignored by Canberra, the group of sound technicians are considering the use of radio "jammers" to disrupt Labor's campaign launch in Mr Rudd's Brisbane electorate. The highly illegal action could disable the use of wireless audio services to be used by the ALP at its glittering launch, to be held at the Brisbane Convention and Entertainment Centre. A spokesman for Wireless Audio Rebels claim they are "individuals who will be bankrupted" by the government's decision to close the 700 MHz spectrum currently used by charities, churches, schools and sports stadiums. Really, we are just doing to Labor what Labor is doing to us. Now every TV station and Labor itself will have to bring two kilometres of cables," a spokesman for WAR said. The Government sold off the spectrum as part of the so-called "digital dividend," raising nearly $2 billion in revenues. But it is demanding all users of the spectrum buy new equipment by January 1, 2015. Kevin Rudd in Perth on Friday. The Australian Commercial and Entertainment Technologies Association - which has spearheaded the campaign - says its call for compensation and assistance has been ignored. It wants a buyback scheme, similar to the one introduced by the Howard Government for guns following the Port Arthur massacre in 1996. ACETA warns that up to 150,000 wireless PA devices will be obsolete within 18 months. These all operate through a "class licence" system - but the spectrum has been sold to Telstra and Optus. The group was careful to distance itself from the self-styled "rebels" behind Sunday's potential illegal protest. "While ACETA understands the frustration of those adversely affected by the spectrum restack, we oppose any action which breaches the law or impedes other wireless audio users," a spokesman said. A spokesman for the ALP said: "Any action taken to disrupt the spectrum will affect not just the ALP but also hundreds of people who will be around the Convention Centre." If the "rebels" go ahead, it could force the venue's operators - and TV networks wishing to broadcast the ALP launch - to use cable services, instead of wireless. We are just individuals who will be bankrupted by this sudden change in policy, which will make our major assets worthless. We have nothing to lose," a WAR spokesman said. At least the U.K. had a buyback scheme when they changed the spectrum. (Former communications minister) Stephen Conroy's office did not even return my call.
