THE arrival of Facebook and Twitter has done little to dampen the enthusiasm of Ipswich's amateur radio devotees.
Ipswich and District Amateur Radio Club marked World Amateur Radio Day with an expo in Booval at the weekend, calling on residents to get involved in the fun.
Club president Glen Woodrow said the hobby had undergone something of a revival in recent years.
"It has never been easier to enter the hobby through the basic Foundation Licence, and the club can show you how to join in the fun," Mr Woodrow said.
At the weekend's Ipswich exhibition, members demonstrated how amateur radio works, as well as showing curious visitors how to get involved.
Mr Woodrow said amateur radio users served their community by providing emergency communications during natural disasters such as floods and bushfires.
Amateur operators also work behind the scenes on disaster preparedness.
"Time and again they prove that even the digital world is reliant on infrastructure that can be overloaded or fail, but amateur radio can still get the message through," he said.
Short courses on the rules of the airways, among other things, can be arranged. Contact Ipswich and District Radio Club via the website vk4wip.org.au.
