    Further back in the forum there is a download for DAB_Master to control the unit directly. It was mentioned that when the volume for the unit was lowered some noise crept in, so it was best to max out the volume on the radio via DAB_Master and then control the volume with CF or Windows.

    Hope that helps, Tom.
    Excuse me, but I searched the forum DAB Master and I can not find?
    You can give me a link.
    Please

    Don't know about DAB Master but http://www.craigbrass.net/radio.zip is available. The same type of software - a raw control application.

    As for your problem in built up areas, was this in DAB+ mode? If so, which aerial / antenna are you using?
    Thanks Craig, good to hear. Yes, it was DAB+ mode, I am using an aluminum (I think) extendable mast antenna. The details are in post #519.

    arachnidia - Craig is correct, his is also a raw control app, but you can find the DAB_Master here:

    I'm going to say it is because that isn't designed for DAB. The 5 and 6 star ones from http://dabonwheels.co.uk/DAB_car_aerials.html work best with this unit. Also, they come with an SMB connector.

    For anyone experiencing ignition/alternator noise problems with their DAB module, I've made an adapter with a piece of coax cable that has a 1nf capacitor in the ground. This has cured the noise problem completely. To see if you're problem is a loop in the ground of the aerial, just disconnect the aerial to see if the noise goes away.

    I can now set the volume level of the DAB, and the line-in, to whatever I need to get the right range of volume with the master volume control without worrying about picking up interference. No need for fancy audio cables, filters etc. Happy days.

    Now just find some more bass from somewhere....................

    Any chance of pictures??
    A am having similar problems, i think, altenator whine plus sometimes the FM signal seems to get "dirty" (hissing?)

    My car is Vw Passat with aftermarket antenna on the roof that i had installed when I got HQCT. When I plug the orginal antenna in I get much worse reception than if I use the roof antenna but still I dont get 100% quality so I am trying to improve it as best as I can

    You need to prove that the noise is from the aerial ground. The first step is to simply unplug the aerial from the unit while the noise is present to see if this removes the noise.

    Did a experiment today. I turned the car on and turned the radio on. I put the radio in FM scan mode and while in scan mode i reved the engine. What I got was a alternator whine. Then I disconnected the antenna and put the radio in scan mode and reved the engine. No alternator whine.
    So I have a similar problem
