Radio Guru's.....
 

Last year I installed A Sirius Sportster at my helm.....can't get rid of the a tiny high pitch interference sound.....everyone tells me to check the ground....I am a Radio install novice....where do I start?? By the way the the unit is not hard wired, I plug it into the cigarette lighter.....

Hey John,

I cant help you with your problem. Dont know chit about stereos. BUT, I called your cell, got your voice mail. Give me a call. I wanted to see what you were doing this coming weekend. I went out on my first run of the year today.
I am ready to go.

Vinny

Most installers will seperate the Pos from the Ground to avoid radio interference. Check your wiring. Also, most guys will tell you to run your ground to the terminal of your battery to avoid other interference.

Install this.

Looks like I will give that a try Nighthawk.........Thanks :drink:

Re: Radio Guru's.....
 

My old truck used to have the same problem and i installed a filter like Nighthawk showed. Worked like a charm.

Re: Radio Guru's.....
 

you can accomplish the same thing with a 3 dollar capacitor. ground the case, hook wire to positive feed to radio. Thats all a "noise filter" is but in a box.

Re: Radio Guru's.....
 

The noise filter also contains a series inductor.

Re: Radio Guru's.....
 

Dont waste your money on that band aid.

Hold on chief. I'm not Mr. engine guru but I am Mr. electronics guru. While that device is a simple thing it is a perfectly legitimate solution to noise and interference, whatever the source, on a DC supply line. It is a series inductor and parallel capacitor that form a low-pass network and it is very effective when installed properly. It's only 12 bucks for Christs sake!. What's the problem?

Re: Radio Guru's.....
 

Most of the time all your accesories at the helm are run off the same ten pin harness that your motor runs off of. That means all your guages, pumps, lights etc are using the same ground. try running a seperate ground to the battery for anything that has to do with your stereo. You might as well run a positive while you are at it to be sure. That will work for noise, if you still have noise after running seperate power and ground then your problem is with the Sirius unit itself.
