Default Technical Bulletin for SIRIUS Echo Signal Repeater System SIRWRS1

Enjoy SIRIUS radio throughout your home without the need to run antenna wires.


The Echo Repeater System makes it easier to position and install your satellite antenna for best reception without restricting where you place your SIRIUS radio
Lets you place your SIRIUS radio in a different room from your home antenna without the need to run wires
The Echo Transmitter connects to any SIRIUS home antenna or home signal distribution kit
The Echo Antenna discreetly connects to any SIRIUS radio

That first statement on the description above can be misleading.

If you don't already have reception with your current antenna placement. This device will NOT, I REPEAT, will NOT resolve this problem. You have to connect an existing antenna to the TRANSMITTER to repeat the signal to the RECEIVER. This will require that you have the antenna placement as such that you get good reception already!

This device is simply a signal repeater... the transmitter repeats the signal it receives from the antenna, which is picked up by the little antenna receiver connected to your home dock or boombox. So there is nothing magical about this device that will improve reception.

What this device does give you is the ability to connect a little receiver to a boombox or home kit so that you are no longer tied to a wire. This will give you some freedom inside your home. An example is having the transmitter setup say Upstairs and you enjoying reception with the boombox downstairs in your living room or den.

This repeater does not broadcast a signal that your Stiletto SL10 or SL100 can pick up with its built in antenna. You would have to have it docked in the home dock or boombox, Soloist with the little receiver connected to it.

I hope this helps any of you that are considering buying the Echo Repeater. I just don't want anyone buying it with unreal expectation and then having to return it.

If you want to share your experiences with the use of these device feel free.

Thanks....

It seems that this is better aimed at people who don't yet have an external antenna mounted. You're better off just mounting your antenna and then just running the wire to the best location for the transmitter. If you already have the antenna run in place and a radio hooked up, then your are forced into adding an otherwise unneeded repeater receiver.
FCC regulations prevents Sirius from rebroadcasting the actual satellite signal in the home, therefore they are forced to do this less optimal approach. I agree what you want is more ideal, just not feasible with the FCC.

Has anyone actually tried this repeater yet?

I was wondering the distance it will send the signal.

I was also wondering what frequency it sends it on. 900mhz? 2.4Ghz?
Will the baby monitor cause interfearence? The Microwave? The WiFi router?

Currently I use my Wifi to get the signal all around the house. I loose the flexibility to pause, stop rewind live radio etc. This would give me that flexability back but at the cost of having to have the unit plugged into an AC outlet.

Anyone know what are the voltage requirements? Could we use a battery to power it?

I see crutchfield has them in stock. I think TSS has them to. At least they don't say they are not in stock.

I'm not sure I would like to spend another 100 bucks for this. I have lots of Home dock antennas stuck out every window on each floor and normally this works for me.

DAB I'm glad you posted the warnings. I just hope people dont think this will make their radio's work like a strong Terrestrial repeater.

I really think it is important for people to reliaze that using this with a stiletto make your stetto much less portable.

I think I will wait for the reviews to start being posted.

How is the distance between repeater and receiver? I saw one person said 20 ft.

Any interference from other home devices? 900mhz cordless phones? Could this be a problem?

Does the signal go through the Floor? Walls?

How about some close up pictures of the device? Connectors? is there a PDF of the user manual we can read?

Thanks.

Just to add a bit more..... The Sirius 'repeater' is essentially a cordless antenna system. It consists of two parts. There is a box (Box A) that you plug the antenna into, and another box (Box B) that you plug your receiver into.

Box 'A' takes the 2300 Megahertz Sirius signal from the antenna wire and converts it into a 900 Megahertz radio signal. Box 'A' then transmits this 900 Megahertz radio signal over the air to box B. Box 'B' receives the 900 Megahertz signal and coverts it back to the 2300 Megahertz antenna signal. This signal is sent over a wire to the receiver.

Note that you must buy a separate receiver (Box B) for every radio you have. A Sirius radio by itself cannot pick up the repeater. (Box B is called the Echo Antenna SIR-WRR1)


Hopefully, the diagram below explains it a little better.



The main advantages of having a cordless antenna are:

- You don't have to route wires over floors or through walls and ceilings.
- There is better range than with a 50 foot antenna extension cable.

Some disadvantages are:

- Cordless phones and other home electronic products operating at 900 Mhz can cause interference.
- The Echo transmitter requires a 12v power cube. You need power at the place you install the transmitter. (The echo antenna is powered by your Sirius tuner

.

Below is a comparison showing the difference between using a Sirius 'repeater' and a 50 foot extension cable.




Finally.. Here is the entire PDF owner's manual for the Sirius Echo Repeater System SIR-WRR1

Thanks for posting the PDF. It answered a lot of my questions. I see the transmitter runs on 12V. It might be interesting to put in the car then have it transmit to your radio outside the car.

The distance can approach on 75 ft as in the products description. I've gotten more than 70 ft so far. The one guy who put 20 feet didn't say it only worked 20 ft just saying that his setup only needs that.

Other home devices, like in the case of the Conductor will probably bring the distance down slightly, but not necessarily.

The signal can to some extent go through the walls and floor.

Yeah, 20 feet is all I needed. That is between 2 floors, so a ceiling and a wall. Crappy cell pics is the best I could do, sorry.

Also, my home phone (cordless) is 5.8 ghz. I also have a wireless G router in use. No interruptions of any kind, no less than 2 /3 signal.

Thanks jtw873, that is a very information well laid out post. I think pictures always explain it better than words.

Just trying to make sure folks understand what they are buying.

I am real curious to see how the SIRIUS Repeater and XM Repeater will play together with them both being 900 MHz. I know the XM Repeater and the Conductor never played well together, so if someone already has an XM repeater it might be worth watching these threads.

Mike in reply to your thoughts about folks thinking it would work like a really strong repeater. We are already seeing post that indicate they are, this is what prompted me to post this Technical Bulletin. Folks also don't understand the FCC will NOT approve such a device for XM and SIRIUS to use either. So this is the only alternative. Sure it would be nice if we could have a true home repeater like they have at retail stores, but that won't happen!

I would modify it slightly showing that the repeater needs to be connected to an AC source for the 12V 2.5mm AC Adapter. Also you can get further distance using an antenna directly connected to the radio.

Good point Mike, I would hope most people know it does require AC power, but it is probably good to point it out since where they locate the Transmitter there does need to be AC power.

You can get further distance using cable connected directly to the tuner, but there goes your freedom and ability to roam around the home without wires.

That diagram is invaluable.

However, I would like to note that outside of the power cord, the first diagram is more effective. The antenna lines up between the two comparisons, and the radio (almost) lines up as well. With an instant glance, you can see exactly what the repeater is doing.

The second diagram is useful to show the power cord as mentioned, but doesn't "snap" into the brain like the first diagram.

The individual Repeater Antennas are now available. One would need them for using the repeater with multiple radios. One per Radio.

Great explanation! There's seems to be a lot of confusion about the capabilities of this device. I think the term "repeater" is one reason.

I think people tend to think this device is an FM transmitter on steroids. Perhaps they should have called it a "wireless antenna."
