Canberra Dab+ Trial

Recommended Posts

The DAB+ trial for Canberra and Darwin is supposed to end today.

There was a expectation that a committee would recommend that these trials be converted to permanent broadcasts.

I don't know if I can't find it thanks to the stupid-broken ACMA site, or whether the page has simply changed in the meantime, but a few days ago this page on the ACMA site was saying:

DAB+ trials in Canberra and Darwin
The ACMA has authorised trials of DAB+ in two regional licence areas where sufficient spectrum was available - Canberra and Darwin. Commercial Radio Australia is conducting the trials. The Canberra trial commenced on 19 July 2010. In February 2011, the ACMA approved an increase in power for the Canberra trial from 1 kW to 3kW. The Darwin trial commenced on 13 August 2010. Both trials have been extended until 30 June 2016. The Digital Radio Report recommends that the Government should consider permanent services be licensed in Canberra and Darwin as a priority.

(emphasis mine)

(edit: Interestingly, also reported in the Smage today as being a statement made today, and the page now matches the above quote. Wonder if ACMA got their botty slapped for putting it on their page last week?)

An extension of another 10 months was not the outcome that ACMA expected.

It's finally going permanent, with a second multiplexer.  So I presume we'll end up with the same situation as other cities...  Lots of stations but all at quite low bit-rates - so ok for background or at quiet levels.  Great for choice, but not for sound quality.

The people of the Northern Territory outside of Darwin, Alice Springs and a few tiny towns have lost all radio signals along with Radio Australia for the ABC to fund your second DAB+ transmitter in Canberra with an increase in power to the existing transmitter. Joining Canberra is Darwin, Hobart and the Gold Coast.

Really? They shut down *all* radio signals in Northern Australia to fund Canberra's second multiplexer?  I did not realise it was that expensive to run ;-)

The $1.9 million each year will be used this year to build 4 high powered DAB+ transmitters. The antennas will be mounted on existing towers. The power to be used will be less than half used by mainland Captial cities. The power of the Short Wave transmitters was considerably higher, hence a much larger electricity and maintenance bills.

Nick Xenophon has introduced an amendment to the ABC Act to force the ABC to restart short wave broadcasting.

Well you may want to start a thread about SW then... This concerns the Canberra roll-out... I'm sorry that the national capital finally moving on from a seven year trial has caused such distress.

Back on topic... Hopefully we'll get higher bitrates...

Does anyone know when this will be happening

Now, now. I think we are getting a little excited ;)

The ABC claims that VAST satellite, Skymuster satellite internet and mobile phones are an adequate replacement. VAST and Skymuster satellite systems require a satellite dish pointed accurately at the respective satellites. The reality is So if you are in a moving vehicle or a boat outside of Darwin, Alice Springs, , Katherine, Tennant Creek, Nhulunbuy, and within 10 tiny villages the phone does not work and neither does the radio.

Go to https://www.telstra.com.au/coverage-networks/our-coverage The low powered FM transmitter coverage is similar to the mobile phone coverage

Satellite phones cannot download and calls cost around $3 per minute.

So not only no live programming but no emergency warnings either.

Well sounds like a good candidate for a separate discussion. I don't see how this relates to Canberra digital radio...

This was the ABC's excuse for stopping HF broadcasting in the NT and Radio Australia to fund new separate DAB+ transmitters for Canberra, Darwin, which are trial sites and new sites of Hobart and Gold Coast.

If the amendment of the ABC act is successful in May to provide HF radio,  how will the ABC fund the above DAB+ transmitters?

I'm not familiar with what bit rate would be required for the DAB+ services to sound as good as FM services but there may be a glimmer of light.. it was announced back in December that the ABC was going to improve the bitrates of their services.
ABC Radio is also investigating transmission improvements to address reception gaps in the existing five DAB+ markets. It aims to ensure a resilient DAB+ service in every capital city, with enhanced bitrates and infill where necessary.

Thank heavens.... Some recognition... We should all thank them for this.
