Macquarie Radio Network Ltd says it has had some informal talks with various parties concerning ownership of the company in the past six months.

"There have been some informal discussions with various parties, but not in a way that ever progressed anywhere," Macquarie Radio chairman Max Donnelly told journalists after the release of the company's first half results.


Mr Donnelly said he was not aware of whether the talks involved private equity groups.

"I'm not aware of any discussions (with private equity)," he said. The operator of Sydney radio stations 2GB and 2CH said it had appointed corporate advisers, Baron Partners Ltd, to look into possible corporate transaction opportunities ahead of the introduction of new media ownership laws.

The company said the scope of those opportunities could include a merger, sale, purchase or other combination with an industry or investment partner.
