Its all coming together... Just bought my self the FM radio for my CarPC - The D-Link DRU-R100 USB FM Radio. I did look on EBay but they were fairly expensive so I nipped down the road ( 60 Mile round trip ! ) to Scan in Bolton (UK). They have them for round £8 which is not bad. This works very well with my Interface and with a bit of planning I should be able to get a decent aerial feed in to it in the car. I have not decided yet whether I will take this off the main aerial and amplify it or put a separate one in. The only problem with that I can see is interference... we'll see.
