Thread: FM/DAB digital radio - THAT WORKS!!

Been concentrating on the rest of the setup while I see what happens with your antenna and looking for a DAB/FM antenna with only 1 cable or a cheap 75/50 Ohm impedence matcher to test or trying to workout if I can replace the antenna amp with one that has no bandpass filter. I got the module and know it works so now only have to get the antenna and the rest of the carpc working

Placed an order for this unit yesterday, now just waiting for it to arrive so that I can test it out Will give you an review when arrived.

Thanks

Yes I did drill holes in the PCB (nerve racking moment ) and then I mounted the PCB on a plastic risers that i got from my local shop to the metal plate. Best thing to do is use special drill to drill the holes (high speed) and i did it in few steps. Started with 1mm i think and ended in 4mm with two or three drill sizes in between. The last step I did with ordinary Dewalt drill. But do this on your own risk

Like I said tense moment

Yes I can imagine! I will think about doing this for mine, thanks for the advice. A drill press might make it a bit safer knowing that the bit is coming down straight on.

Thanks Again.

Craig thanks but I want to put this DAB PCB in my mini ITX case (it would replace existing HQCTi PCB) however don't have any further space for a USB Line-In device no matter how small it is.

For example I have D945GCLF2 from Intel and there I can decide if I want for example 5:1 or 4:Mic in or 2: Micin/Lineout ( hope that you can understand this

My self is not using the audio option on the motherboard but instead I use Soundblaster Live External and I have disabled the audio part of the motherboard in the bios menu but I have tried the onboard option and that is why I know this.
Hope that this helps

Thanks. My 3 X audio phone jacks (Line-out, Line-in and MIC-in) support/auto detect 5:1 channels comprising 2 X front speakers. 2 X rear speakers, 1 X sub and 1X front centre speaker. I would have to lose 2 X channels to free one up for DAB but more importantly I want to place my DAB PCB inside my mini ITX case so wiring that to a a external audio jack is very messy compared to simply wiring to a onboard audio connector. Keeping everything inside the case precludes adding external sound cards.

You are now using HQCT and in that config you plug the audio from HQCT into the "CD in" plug on your motherboard using cable with CDin plug on both ends.
As i understand you want to plug the audio from the DAB module straight into "CD In plug" on your mobo?
I can not see that as a problem. You would of course have to make your own special plug with 3.5mm plug on one end and CDin plug on the other but that is just a part of the fun of building your own carputer.
I had myself a HCQT and I did it the other way around. I put the HCQT in a special box and made my self special cable with CDin on one end and RCA on the other. then i used RCA/3.5mm cable to transfer the signal to the Soundblaster External Line in (around 5meters)

The reason why I used RCA is because RCA is easier to soilder

I think that 3.5mm/RCA/CDin plugs are basicly the same thing and the audio signal is just the same but if I am wrong then please someone correct me


ps:
To all: I want to say sorry for all my spelling errors that I make when I write here on MP3Car. I sometimes have problem in writing correct english.
My icelandic is much better but then no one would understand me

Hello Everybody.

First i want to thank everyone that have something to do with this amazing module.
I received it yesterday and i am now getting CLEAR sound from it. The sound quality is unbelievable.

But, since the ultimate radio does not work yet i installed the CF plugin (i use CF in my car) but its giving me some problems. When turning the DAB card on it starts a channel search.
At 98% it says it found 19 stations and starts to play one of them (NRJ Norwegian Energy). The problem is that the message "Scanning...." does not go away. When i push F4 to cancel the search its just telling me no channels found, but continues to play the channel its already started.

Reception should be good, the one channel i do get is clock clear.....

Any ideas?

I know I keep saying this but the update is SO nearly ready for both standalone and Centrafuse. We have about 5 people testing it at the moment that I am sending daily updates to. I want to get it perfect before the next build.
