The reception is not as great as these executives infer.
http://reception.abc.net.au/Reception.aspx shows most of the coverage is out to sea. The transmitter channel is surrounded by those for TV. https://myswitch.digitalready.gov.au/ shows a much more detailed coverage map. TV is 2.5 times more powerful and the receiving antenna can be up to 10 m above the ground for reception. The mountainous terrain of Tasmania blocks reception which is why there is many TV translators. DAB+ will need repeaters on each site. An alternative is Digital Radio Mondiale (www.drm.org) which operates at much lower frequencies which are unaffected by the terrain, allowing continuous reception when driving cars anywhere in Tasmania. Each DRM+ transmitter can cover much larger areas than DAB+ and can carry 3 audio programs and there are 178 transmission channels compared to the 8 available for DAB+.
DRM30 is also available which uses the AM and High Frequency (Short Wave).
