More Digital Radio Mondiale (DRM) on Radio Australia

It should get easier to receive high quality short wave digital radio mondiale from April 1, 2012.

"RA will commence a DRM schedule from its main Pacific station at Shepparton, Victoria, from 1 April 2012. Average power is 40 kW from a Continental 418G transmitter. Reception reports welcome especially notifying interference to the RA transmissions.

Broadcasts to central Pacific may also be audible in North America; broadcasts to the south-west Pacific and PNG may also be audible in eastern Australia. Broadcasts to south-east Asia may be audible in Europe."

Here's the new schedule from Radio Australia. Times in UTC.

It's great to see DRM starting to get some traction. The combination of All India Radio, Radio New Zealand International and Radio Australia means that there will be plenty to tune in to. The AIR DRM schedule is here.

Now we need a new generation of low cost, low power consumption receivers to make it take off.

Update


Bad news I'm afraid. It looks like management have decided not to go ahead with the DRM transmissions from Shepparton at this stage. Very sad.

G'day folks. I have to confess I was responsible for the advice of a DRM trial kicking off from RAs Shepparton IHFTS last year. Unfortunately the draft DRM schedule was disallowed by TPTB (Buffy). But a shiny new Continental 418G tx is there just waiting.

Australia should get behind DRM30 and DRM+ for the upper bands, DRM30 makes so much more sence becouse of its large reach (for example the outback) and radios should come with DAD+,DRM30 nd DRM+ all in one stand alone receiver. screw HD radio!
