Weather causes TV woes

A COMBINATION of weather conditions and a restack of digital television services across the country are the reasons Shoalhaven residents are experiencing interrupted television services.

The hot weather the area is experiencing is producing a phenomenon known as ducting, where unusual atmospherics disturb the television signals.

Member for Gilmore Ann Sudmalis said she had received many phone calls and emails regarding poor TV quality throughout the electorate. 

“I understand the frustrations of viewers watching their favourite programs when, at the worst possible moment, reception drops out – right in the middle of the tennis or cricket, our January favourites,” Mrs Sudmalis said. 

She said as some TV channels change their frequency as the final step in the move to digital-only TV, residents will need to retune their TV, set-top box or digital recorder.
