    Me experiences with the D-link USB radio

    OK, this weekend I took the plunge and wired in the D-link USB radio to use with Confused's radio skin and radiator within MediaCar.

    I had the PC out of the car and on the bench, installed radiator, as I had Garry's latest skins, everything else worked fine. I saved several stations tested MediaCar functionality, all seemed fine.

    Next I cut into my aerial lead just behind the HU and plit it in two, sent one to the HU and one up to the glove compartment for the D-Link. HU functioned fine, tested for signal, tuning etc all ok.

    Installed the D-link into a 4 port HUB behind the glove compartment, attached the aerial lead (phono connector fitted) and sent the audio down a screened cable back to to the PC in the boot.

    Hmm, how dissapointed was I, very poor reception and engine whine.

    Now me thinks that the engine whine could be fixed by building the D-link into a metal project box and I have such a thing ready for next week, but what about the poor reception, has everyone else had this problem?

    I seem to remember several threads regarding the radio reception quality.

    I have yet to try this...but I quite probably will be next weekend.

    One thing I seem to remember from reading here, is that the ground is actually on the inside of the phone connector, and the signal on the outside.

    I'm glad all the functions worked...just apart from the reception

    Bugger, I seem to think your right. That all makes sense now. Anyhow, I will build it into the metal box and add a filter or two, I will be removing the phono socket, so I will be able to see what is ground and what is signal, thanks Garry.


    Still got my shutdown controller to install, ran out of time this weekend.

    Spliting the signal will cost you some reception quality

    I did the same exact thing.

    I should have taken pictures, mine has the standard car antenna male and female connections.

    I did alot of testing on it. I took and grounded the outer conductor to the line out's outer conductor and it got rid of alot of the whine.

    Next, I unplugged my headunit antenna and some more noise went away.

    If you mute the line in the noise will go away. - I wonder if there is some program that mutes and unmutes the line in when the radio is in use and not.

    I cut mine apart and the center pin is what is soldered to the base of the antenna. It is odd that there are people using it both ways and both seem to work

    I tested mine and made sure which was the signal and ground.

    OK, I need to know what everyone hooked up the center antenna conductor to and what they grounded the outer sheilding of the antenna wire.

    I hooked what is circled in blue up to the center pin/wire on my cars antenna wire.

    I also think I know why the whine is coming in... I'm going to see if I can make this thing work really nice now that I'm gonna go headunitless.
