Digital Radio Technologies
Hello! This website started life as an easy to find link to my web pages about DRM™ digital shortwave radio reception in New Zealand. With the start of DAB trial broadcasts here in New Zealand it has been expanded to cover that form of digital broadcasting. I hope you find it interesting.
The current Kordia DAB pilot multiplex contains two streams of Radio New Zealand's RNZ Concert service, one a 192 kbps MP2 (DAB) stream, the other a 64 kbps AAC+ (DAB+) stream. Here are examples of both streams, recorded off the Blik RadioStation, and encoded using FLAC lossless encoding:
Some longer recordings are available via ed2k file sharing:
After some initial teething troubles I can now get very good reception from my Lambton Quay office (subject to being away from the general noise of PCs etc). Here are some samples, recorded during April 2007. These files are straight off the SDRAM recorder card in the Morphy Richards so are at the same bit rate as the DAB audio stream. You will need a broadband connection to listen without rebuffering.
The Morphy Richards DAB/DRM/LW/MW/SW DigitalRadio 27024 receiver is
now available from various sources in Europe. This multi-standard
consumer level radio also features an SD recording card.
I wrote a review of this radio for
the April 2007 issue of the
New Zealand DX Times magazine.
