On 25th June 2013 Bunbury TV stations moved to UHF allowing 87.5 – 92, 94 – 108 MHz available to FM radio.
Now, the ACMA is offering frequencies to 9 Radio’s 6PR, 6IX, ABC Perth, Radio National, ABC News.
In the 1990’s the ABC refused the offer to go FM in capital cities except Darwin. The only AM stations left would be SEN and TAB Radio. Perth’s dry sandy soils reduces the coverage area of AM radio.
In 2009 all mainland State capital cities were the first cities in the world to start DAB+ digital radio full time broadcasting. 1 ½ years ago Mandurah commercial radio converted to FM and added DAB+
With the main DAB+ transmitters are on the Darling Scarp and a ‘flat’ coastal plain containing 2 million people it is an ideal site to mimic the 5 million Norwegians and switch off analog radio networks in 2017. It took a year for the ratings to recover and have risen since then.
CRA states that 77 % of all new vehicles contain DAB+ receivers and there are converters are available for older vehicles.
The BBC Research has found that the most expensive way of distributing broadcasts is AM radio, Mobile internet, fixed internet, FM and DAB+ is by far the most economical. This means that 24 high powered transmitters can be decommissioned, however there is no backup transmitter for the two DAB+ transmitters which are 12 years old.
Between 2010 – 2013 television switched off Australia’s analog TV transmitters making huge ongoing reductions in electricity consumption. Radio could follow this model using Perth first because it is a smaller city but big enough to drive down receiver prices as well as greenhouse gasses.
