While Nova FM were celebrating broadcasting their drive show from 35,000 feet onboard a private jet, 92.7 Mix FM on the Sunshine Coast took their breakfast show underwater.

This morning, Mix FM made Sunshine Coast broadcast history by being the first radio station to broadcast underwater, from the deck of the wreck of HMAS Brisbane which settled on the ocean floor almost 10 years ago.  Orginally the plan was to have breakfast co-host Caroline Hutchinson get her diving licence for the occasion, but there was just one problem.  Caroline gets sea sick.

But the show must go on, and to help the station achieve this feat, they roped in local Councillor Jason O’Prey, who broadcast parts of the breakfast show from 3 nautical miles and 28 metres off the Sunshine Coast – and proving that politicians can talk underwater.

So how did they do it?

The team used Dive Buddy gear, which uses 32khz utilizing sideband modulation, just like on an old CB radio.

The communication gear had a transducer that was dropped overboard which received signals form the diver’s masks which, after modifying the speaker output, was streamed via 4G back to the station.
