Is there a way to shield this ipod car charger?

[Jahn]

When i use the ipod as a fm transmitter in the car off of the ipod's battery it's no problem (well, a high freq whine but i can eq that out- PodFreq is a good system) but when I plug the sik imp car charger into the ipod the fmtransmitter gets all hummy and unlistenable.

is there a way to shield the car charger cable so there is no hum? My poor ipod's fm frequencies are getting seriously disrupted by that damn charger. Thanks! (of course if the ipod had a bigger battery this wouldn't be a problem...but full charge only takes me 3 hours when the podfreq is activated)

That probably has nothing to do with shielding. It sounds like you are experiencing ground loop noise.

EDIT: To use a ground loop isolator you'd have to be connecting via rca.... since it's an Fm transmitter, I dont know what to tell ya man.

I have a similar problem with my iPod (using a wired input). Only when using the charger there is a whining over the car's sound system that is RPM related. Anyone have a remedy?

ah so it's a common problem, ugh. i remember way back when i bought a rectangular magnetic thing that clipped onto a cable to reduce hum - don't know how it worked but it did. it's buried in the desk of my room at my parents house - is it worth using something like that to remove hum, or wouldn't that work?

YEP! I had the same problem, a ground loop isolator will fix it. You can buy them at Ratshack from about 15$. If you want better quality cables, Griffen makes one too.

I don't think it would work since you are using an FM transmitter.

i had similar problems with my iPod in my car and decided that FM just wasn't the way to go. my car stereo has a tape deck with an optional external CD player. since my car didn't come w/ the audio "upgrade" package, i don't have the CD player. i was able to buy a converter to go from the stereo's custom CD player attachment in the rear of the unit, out to RCA.

I ran the RCA cable down into a small storage compartment in my car's console area, which is where i keep the iPod while driving. The sound is certainly much better than any FM or tape deck solution i've heard. I havn't tried using a cmoy w/ it yet, but that may give it a little more love.

good luck!

You could try using a different power adapter.

I had a ground-loop hum from a cheap set of computer speakers, except the hum only occurred when using one particular power adapter (I have two) for my iBook. I tried different outlets in the apartment, but nothing worked. Since the power adapter worked fine otherwise, I used the problem as an excuse to upgrade the speakers
