I have done dj work with a laptop, a Dell Inspiron. When I hooked the line out to a mixing board, the noise was terrible. I lifted the ground to the computer by using a ground adaptor with the wire not connected and it got rid of hum and noise. I have a old small tower HP with a Soundblaster card feeding a small part 15 AM transmitter to broadcast to my old radios and experienced the same thing. Lifting the ground quieted things down. Ground on the input of the power supply is not the same ground from the soundcards.

:Perhaps a little off topic, but anyway once a week I like to record a show off my Panasonic RF-2200 for later listening. I connect the line-out from the radio to the line-in of the sound card. The radio is about 20 feet away from the computer. When not connected to the sound card, the signal is clean. When connected, there's low level intereference. It's not tooobjectionable, but I was wondering if there's a way to virtually eliminate it? Thanks.

Many thanks ! That did the trick. The recording sounds good to my picky ears.
