Sporster 4 FM transmitter

The transmitter on the Sportster 4 is terrible, tons of static. Much worse then the Starmate. I have looked around it seems that I will need wired fm modulator to plug into my radio's antenna. Has anyone used one of these things? Do they work ok? Where can I get one?

I've had lots of success boosting the signal using the little wire and the FM out jack in the base of the cradle. That worked wonders in my car with the Sportster Replay. I've posted on this site before about using a $5.99 ear-bud from the source to do the trick.

Today though I decided to be a bit more "do-it-yourself" so I followed these instructions without a hitch:

Worked like a charm and boots the signal immensely. Using that for the FM transmitter on my other car with my S100.

So while there's no doubt that the FM direct (aka FM modulator) is a great way to go, it's also $25 plus you have to pull out your car radio. With very little effort there is the $2.99 method that I did today and worked very well for me. Or if you don't even want to do that much, there is the $5.99 ear-bud solution discussed in other threads on this topic.

Just some suggestions for anyone who may want to try other solutions that have a fairly good chance of working for a minimal cost and effort.

Yes, the boost is nothing short of remarkable. First I tried it with my car dock hooked up in the house. I tested with my regular audio receiver (which is primarily for TV/DVD). It received the Calgary radio stations anywhere from somewhat static-y to somewhat decent depending on the channel. With the Stiletto car dock about 3ft away, my audio receiver got nothing - absolutely zero. Then plugged in the wire I built as per the link and it went from nothing to perfectly clear.

So in my car where I was getting a so-so signal already, the new wire made it completely clear. Plus I tucked with wire in behind the plastic molding on the dash making it almost completely out of site.

An awesome solution for me for only $3.00!
