Car radio -> Computer room
My car radio has always seemed to get excellent radio reception, so when
I decided to replace the stock head unit (2002 Mustang), I kept the radio/cd player and later set it in my computer room in the house to add as an audio input to my computer. I figured out the wiring and got power, ground and acc wired up and two channels out were plugged into my sound mixer. I bought a radio antenna at the electronics store and and antenna extension cord and listened to the sound quality. It was lousy, just as bad as the cheap radio I already had in the room. I experimented with antenna location, in the window, out of the window, up on the roof of the house. It didn't change for the better. So what gives, why does my radio get so much better reception when it is mounted in the car? The very confused, John |

Offhand I'd say the RF from the computers are messing with your deck.

And what RF would that be?

Computers use switched-mode power supplies which emit RF radiation. It's
possible that enough radiation is escaping the chassis to interfere with radio reception. Kevin "Matt Bhame" wrote in message ... And what RF would that be?

You'll need to use an earth ground for your antenna. Any metal piping in
the house will give you sufficient ground, or just ram a 6 foot stake into the ground and connect that to the decks chassis. I'm assuming this is reception, and not just lots of whine and buzzing. If you're getting that, then it is most likely a ground loop caused by potential difference between whatever power source you're using, and your computers power supply. Youll need an audio isolation transformer, which can be found at most rat shacks (used for phones). I forgot what its like to answer AUDIO questions since the crossover of the Bush haters.

I have the radio grounded to the -terminal on a 12 volt battery, but there is no ground wire on the antenna. Thanks everyone for the input. John |
