Possible to Boost FM Transmitter?

Default Possible to Boost FM Transmitter?

Living on Long Island, the FM Band seems noisy. Even when I find a quiet spot on the dial, I can barely pick up my Xact XTR1 in the other room, on my clock radio. Since the Stream Jockey is also connected to my stereo, I really can't move it without rearranging the whole room.

But, is there a way to boost the FM Transmitter Signal? I do get the signal and some days are better than others. It's just so filled with static that it's not enjoyable. If I get a second transmitter and connect it to the headset slot and transmit on the same frequency as the built in transmitter, would that help or cause more interference? Would a stronger transmitter instead of the built-in one help? Or does a device that boosts the system exist?

Any suggestions would be appreciated.

Thank you.

Theoretically... Sure. You can buy a power amplifier and boost your signal. The question would be... from who?

Or, you could buy an FM transmitter or kit. Something in the 100 mW range would be powerful enough to reach all parts of your house without bringing the FCC down on you. CCrane sells one for about $70. Look for other models on e-Bay. (Search for FM Transmitter.)

You would disable the FM transmitter if you use an external FM transmitter to prevent interference with yourself or others.

I used a suggestion I found in another thread titled "FM out tip for home." (sorry, I don't know how to post links directly to other threads). You buy a monaural earphone (cat #33-179) from Radio Shack, cut off the earpiece, and plug it into your FM out jack. It worked like a charm for me. I now get excellent reception on every radio in my house including a Walkman, a clock radio, and a shower radio.

Yup, try this first. If it doesn't give you the boost you need, then look into an external FM transmitter. This wire at RadioShack is only$3.99 and the difference in signal strength is night and day.

I was going to suggest this too.

Thank you everyone for your suggestions. Unfortunately, the Xact Home Dock doesn't have an FM Out Port.

But, I did try something else that may work. My Clock Radio has a connector for an external antenna. So, I strung a wire from it towards the room where my Sirius Radio is and the signal comes in stronger now. It's not perfect and I do have to see how noisy the bandwidth is in the morning but I am hopeful. If this doesn't then I'll opt for the FM Transmitter.

Thanks again and Happy Holidays!

crack that sucker open, find the antenna... and make it longer with any kind of wire... that's essentially what the fm out trick is doing... you elongate the antenna and get better reception.... I have mine so it runs to the back of my car.. under the seats, where my car antenna is

The other option is to get an external FM Modulator. It will cost you some, but it will give you a powerful signal that will reach anything in your house with perfect reception. And it'll reach your neighbors too...

FYI - it plugs in the LINE OUT on the home kit.

Does the Radio Shack earphone wire work better than the little FM Transmitter Antenna wire provided with the Sportster car kit? I've been using this wire at home and it seems to help a bit. Just wondering if the Radio Shack $3.99 earphone wire would make a bigger difference in sending the signal throughout the house.

Thanks.

I've never done a side-by-side comparison but I would guess they're about the same. They're just wires, no special circuitry or anything.

I did a little experimentation and found that a slightly bigger wire (18 awg) worked noticibly better than the smaller wire that is included with the Sportster kits (and presumably the radio shack earphone as well). I ditched the Spotster wires and use my homemade TX antennas in the apartment. Works like a charm!

Thanks for tip. I'm a newbie when it comes to Sirius, and radio technology in general. Could you be more specific when you suggest a "18 awg bigger wire?" And will this wire have the proper plug (size) on the end to plug into the Sportster Home Kit?

Do I go to Radio Shack and ask for this type of wire? I'd love to follow your recommendation, I just don't know what I'd be talking about, where to get it or where to start.

Thanks so much!!

Is anyone familiar with this product:
http://www.wholehousetransmitter.com/

It claims to be able to transmit throughout an entire home. Has anyone tried this? I'm skeptical because they don't offer any specs.

What do you think?
