Default fm transmitter

I've had the sirius sportster SP-R2 for a year and a half. This unit came with that short little fm transmitter. I returned the unit to Best Buy for warrenty replacement because my antenna was shorting out. The new sportster comes with the built in transmitter. I HATE IT!! The signal is horrible. Every five minutes i'm fishing for a better fm channel. i want that same transmitter from the old sportster. Where can i find it. It's about 4 inches long and just plugs into the base. Sirius will not give it to me. I don't want the transmitter that connects to the radio since I take the radio out with me to use in my other car.

I had the same problem when I had to return my Sportster Replay. Stupid me gave back the box with that little wire in it.

I had remarkable success fixing that problem using these instructions (which I got from another post on this forum although I can't find that thread right now):

http://www.pokerpulse.com/2-5mm.htm

Total success - signal quality is a few orders of magnitude better. Or another alternative is to get something like this and cut the ear-bud off:

http://www.thesourcecc.com/estore/Pr...roduct=3301003

The key is that it has to be an earphone with a 2.5mm jack (not the standard 3.5mm size).

I've personally had nothing short of fantastic success this way (in both of my vehicles) with very little effort and at a minimal price. Tucked the wire part behind the plastic molding of the dash so it is virtually invisible.

Or, the FM modulator (FM direct) solution that is discussed extensively on this forum is probably an even better solution but a bit more pricey and complex to install (depending on how hard it is to get to the back of your radio).

Question Thanks, North

I've had trouble looking for the 2.5mm earphone here in New York at the chain electronics stores. Has anyone found them?

Can I just use a 1/8 to 3/32 jack adaptor which I see at Radio Shack for $5 and use a regular 3.5 set of stereo earbuds? Does it matter if the adaptor is a stereo ot mono adaptor?

Thanks,
GMan

I just have to say I just tried the 2.5 earbud from my old BlackBerry 7290 and I really have to say I don't hear any static anymore on my Starmate Replay 4!!! I was just listening to stern and no static!! That's awesome!

Just made an antenna and it works great. It works much better than the FM extender which I was using initially. It took me under 10 minutes and cost me about 7 dollars to buy the stuff needed from Radioshack to make two of them for my car and my wife's car. Great fix if you don't want to have your dashboard taken apart to give you a direct connection, and the best part is now I don't have any static.

I have seen the ear bud piece in the headphone section of Radio Shack. I think it's maybe $4.00. The FM cable is mono.

I have a 2.5mm stereo plug and cord, and it works fantastic on my Starmate I. The only thing that I have noticed is that with the stereo plug, if you push it in all of the way, you lose the FM signal. So I pull mine out about 1mm and it works fantastically.

I'm no electronics expert, but I am guessing that this is because the extra contact on the stereo plug is casing a short, and if it isn't in all the way, this is avoided.

The range of the FM signal improved dramatically. Without the antenna the radio is fuzzy in the same room, about 8 feet from the stereo. With the antenna, I can get a clear signal throughout my house, in the yard, in the garage, and even down the road about up to about 8-10 houses away. Crazy!

Keep in mind that this is an older model with the stronger FM transmitter in the first place...
