The ACMA issues the licence for terrestrial TV stations
SBS channel 29 Logical Channel number of a Digital receiver is 3##
ABD 30, 2##
NTD 31, 9##
TND 32, 1##
DTD 33, 7##
Please note that DTD 33 will only be available in digital and not analog.
Please let me know if the last 2 Logical Channel Numbers are reversed.
So search for channel 33 on the installation menu for your newest station.
All of the above stations are 85 kW effective radiating power. ABC and DTD have an 125 kHz offset.
DTD is owned by the other two Darwin commercial stations.
It is unlikely that the new signals will appear on the satellites for unencrypted viewing for copyright reasons. Also Optus Aurora is only carrying signals for Central Australia and not Darwin.
The Department of Broadband, Communications & the Digital Economy is yet to make up its mind on the rollout of DTV to remote areas such as yours. I hope they upgrade to MPEG4 which would give you 2 HD channels for every channel in use now.
What about Austar? Is it going to be picked up by them?
