Default Personal repeaters

Years back there was talk of Sirius releasing a personal repeater of sorts that you could use in your house/work etc. I need this for work. I have an area I can pick up the SAT signal, but I can't run the cable to where I work. This is where the repeater would come in handy. Any ideas if Sirius ever released this or plans on it still?

There still is a lot of talk on the subject.. Lots of desire.. But no repeater yet.

I think whoever markets one will be laughing all the way to the bank..

I have one and it is awesome! (Signal anywhere in the house plus the detached garage)

I am sorry to say that I tried hooking up my wifes SIRIUS XACT Visor to it but would not work.

What about hooking it up an XM antenna to the transmitter, and hooking up the VISOR to the receiver?

There's something I'm not getting about these repeaters. Case in point:

For about 8 months, I operated a Starmate Replay with an XM home antenna with the absolute same results as I'm getting now with a genuine Sirius antenna. Like the poster before me suggests, why not just connect the XM kit exactly as it is advertized but at the very end of the food chain, use a Sirius radio that has an antenna jack that matches with the Delphi's remote antenna connector?

Given that the data streams are neighbours and units don't usually filter adjascent signals at that frequency renage, It's got to work! No?

Sorry, I tried everything. NO GO.

How far do you have to go? Check the threads on extending the FM transmitter range.

The antennas do have filters centered for each service, but are not a very high order of implementation. This allows a XM antenna to work fairly well with Sirius. The Delphi XM Repeater is a totally different animal. To receive FCC certification and maximize performance, it employs a series of narrow bandpass filters. Besides reducing the Sirius signal, the filters also introduce nonlinear phase characteristics to the adjacent band of frequencies. This is particularly damaging to the PSK type modulation used by the satellite downlinks. Due to the signal attenuation and phase distortion, the Delphi Repeater shouldn't be expected to work all that well with Sirius.

A good demonstration of the repeater's performance with Sirius was posted last year.

Repeaters aren't very complex devices from what I understand. Just recieve a signal, boost it, and rebroadcast it. The trick is making it not pick up and amplify its own signal.

Surely somebody with a technical background could make one using an existing Sirius antenna and a project box from Radio Shack, and post the materials needed, and where to buy them. Anyone know any HAM operators with the knowhow to make one? The Sirius signal is 2.320GHz to 2.3325GHz.

MMM... I hadn't thought about that. I might give that a go. It's kind of far though. Like 50 feet.

"The distance the FM transmitter can go will very greatly on your environment and quality of FM Receiver so providing an exact distance is not possible. We do guarantee a minimum of 150 feet when setup properly and using a FM Receiver of reasonable quality. "

Exclamation Look at Circuit City and Best Buy kiosks

I hope someone has access to Circuit City or Best Buy and can check the requirements that both companies have for their in-store kiosks. Both companies have FCC licenses for very low-power repeaters for use in retail stores, and they are designed exactly to provide signal for the in-store displays. You might have noticed that most kiosks in CC and BB use the real home antenna to get a signal (and are not hooked to some hidden wire).

Some models of the in-store repeaters retransmit on either the "SAT2" or "SAT1" parts of the band and will show full-power SAT signal on the signal indicator screen of the receiver. The FCC applications do not mention if there are models that use the "TERR" band but I think a TERR repeater is unlikely to be used due to interference with strong local repeaters (especially in the case of XM).

I'd love to know more about these in-store repeaters!
