    Thanks, I thought so I just wanted to confirm before I put it all back together Will have some more pics / results soon.

    Why is this plugin taking so long? It seems like forever.

    Bit more of an update from me, went for about a 20 min drive to go for a ride on the mountain bike, and 20 min back again. Open roads, upto about 100kph, DAB+ and FM were perfect the whole way

    I tested DAB+ on the way there, and FM on the way home. Going through a tunnel that was about 200m long the FM crackled a little bit, but it was negligible. I didn't have the DAB+ running through the tunnel on the outward journey.

    Only problem seems to be that I have a bit of noise creeping into the system somewhere. I think it is from power cables for the computer or amp, it was present even when I put the radio into standby via the DAB_Master.exe. I have a feeling it's because I am using a normal household 3.5mm stereo cable. Has anyone heard of / used an automotive standard shielded 3.5mm cable?

    So far I am very happy little more tweaking to do, but it seems to be a goer here in Aus, especially as we are on half Tx. Big thanks to Kev, Craig, nrgizerbunny and everyone who has helped with this unit.

    Craig - Some suggestions as I assume you would like feedback. I understand that putting it in a nice shiny box would probably jack the price up a bit, but I think it would be well worth it for perhaps a v2 release. Failing that, some pre-drilled holes to drop it onto some risers would be good. I saw some in the middle of the PCB, but they are a bit tricky to get to. Sort of on the same line is the USB connector. It looks like its really only attached to the board with the terminals / connectors it uses so without the metal surround of the connector being against a case/bulkhead it can be a bit flimsy. Especially with that USB-B connector or what ever it is, it needs a bit of force.

    Cheers, Tom.

    soyfish,

    I'm glad the system works, I hope it lives up to your expectations.

    With regards to noise, yes this can be a problem and is usually down to the quality of stereo cable and connectors that are used. I use switchcraft connectors and 6.3mm diameter bandridge cable that is double screened. Given the nature of car pc power supplies it is inevitable that there will be high frequency noise all over.

    I would recommend the double screened cable and see how you go.

    Sledge, you have a soarer yeah? Not sure what the antenna setup on them was, but I remember that they seem to have pretty complex and integrated systems, so you might be best just to spring for one of the dedicated antennas from the UK or something ...

    Well done Tom.
    Seems the old non-amplified extendable-rod antennas could be an easy substitute to get decent DAB+ reception until someone finds a single cable version of an FM/DAB antenna.
    Glad I could help.

    Hey all, anyone know how to program these directly? I've coded my own frontend for my carpc in .NET and need to create a plugin for it so I can control this radio.
    Contact me directly via the contact form on http://www.coolapplab.com after you have made a purchase of at least 1 unit and I will send you the documentation.

    Hey Craig do you plan to release a Windows 7 Media Centre plug in for this? I know here in Australia theres a whole community waiting for DAB+ for there media centres
    Added to my notes and I will look into it.

    All being looked into.

    Update will be released tonight. You will see with the changes we have made why it took so long.
