How to diy a DAB radio tunner?

[garbage]

i was wondering about the same thing after hearing one of those portable units at a local electronics chain.

the unit was indoors and sounded real clear, with those normal portable type of antenna.


maybe some brave souls might want to order a DAB evaluation kit.

No offence, but this strikes me as a bit pointless, unless the main aim is aesthetic (like those ones shown in the post above).
In the UK, DAB has appaling sound (mono in many cases!), as the bitrate is pathetically low in order to squeeze as many channels as possible into the available bandwidth.
Check out this link to see what I am talking about.

I've just started looking into a DIY DAB radio tonight. I have contacted radioscape about the price of there evaluation kit and the basic RS200 module.

The Dab chip itself that is used in the above is a TI chip that could only be used with a professional PCB as it's a complex multiple row package. So building a DAB from components seems out of the question. Although phillips appear to do more lower level chips (dab decoder and mpeg decoder) built onto a board with a long row of pads down the side, to use these you would need to implement the microcontroller yourself.

I'll let you know what radioscape say about there module prices (if they sell single units), and keep looking for others.

In the meantime there are certainly a lot of suppliers for such components.
Here an example:
Frontier Silicon | Digital Audio

Frontier Silicon | Digital audio products | Venice 5 Lowest-power, lowest-cost module for DAB/FM radios

I wonder, why until now nobody have realized a diy project by using this DAB modules.

Yes, why? In the UK DAB is awful, worse than MP3, because of low bit rates. Much better to build an FM tuner and enjoy genuine high quality broadcasting while it still survives.

another possibility it could be, to buy a cheap radio for tweaking like the DAB+ radio Microspot RA318 (RA-318) resp. King Champion "DB-32F" (DB32F) like by the showed pictures.
King Champion | Products

Here the associated CH threads in German:

"United Kingdom" is not the whole world. This year This year will be launched in Germany DAB+, maybe next month.

also of interest for diy a DAB+ tuner(supports also FM-Stereo/RDS):

Introduce of S/P-DIF (SPDIF) digital output by a DAB receiver
I have found by chance a gallerie for refitting a S/P-DIF output (SPDIF) for follow model from Argon-Audio in denmark:

you will find all steps therefore.
