XM Radio Information

XM Satellite Radio Inc. is one of the major players in the satellite radio industry, with over million subscribers and spreading all over the American territory. XM Satellite Radio Inc. deliver over channels of radio to an ever expanding customer number. Here are some of the characteristics of XM Radio:
Corporate headquarters: Washington, D.C.
Date of launch: November ,
Satellites in service:
Available satellite radio channels:
Monthly subscription cost:$.

XM Satellite Radio Inc. is the owner of one of the FCC approved licenses for delivering digital radio in the United States. Since it only shares the field of Satellite Digital Audio Radio Services (SDARS) with Sirius Radio, XM Satellite Radio Inc. has plenty of room to develop and expand. was the year when XM Satellite Radio Inc. began broadcasting – progress was slow at first, but soon after satellite radio began skyrocketing as a social and economical phenomenon. Since it was the first national digital satellite radio service provider, XM Satellite Radio Inc. captured an important share of the market and started offering music programs and other types of shows and channels like talk shows, sports, comedy, science and news. XM Satellite Radio Inc. owns the most impressive digital radio equipment and facilities, boasting over end to end broadcasting studios. The digital radio used by XM Satellite Radio Inc. is encoded using the complex CT-aacPlus technology which is broadcast in kb/sec format – very close to CD quality. The signal produced by using this technology makes the transmission much clearer and more accurate than any analog radio provider could ever offer. There are no noise disturbances that were often present with FM and AM broadcasts and the transmission is crystal clear. The fact that the signal is received in digital form solves many noise disturbance problems and the output is close in fidelity to the original track.

The XM Satellite Radio Rock and Roll satellites

XM Satellite Radio uses two of the most potent commercial satellites, which are constantly orbiting the Earth at a height of miles. The two Boeing HS- satellites have some inspired names – “Rock” and “Roll”. The first of the two satellites, Rock, was launched in orbit on March , and is currently positioned at degrees West Longitude. It services the western half of the United States and complements the range and area of coverage of its younger “brother” – Roll. Roll was launched on May , and it currently positioned at degrees West Longitude, and it services the eastern part of the United States. The combined coverage of the two satellites spreads beyond US borders and reaches areas like Canada or Mexico. This is an interesting feature of satellite radio, as it further points out the benefit of not having to switch radio stations during long trips or while moving over the border. For emergency purposes, the company has third redundant HS- satellite on the ground, ready to replace Rock or Roll if any of them fails. Both satellites use different transmission frequencies which prevents interference.

Using the XM radio transmission

The powerful broadcast signal used in satellite radio means that you only need a small receiver in order to be able to listen to digital radio. These small omni-directional antennas are similar to GPS devices and do not require mechanical pointing in order to receive the signal. Some of the new features of satellite radio refer to the extended broadcast information abilities. XM offers information about the broadcast type, and includes the song title, artist, and genre of music. As a recent improvement, XM radio also started broadcasting weather related news and traffic statuses on their programs. In order to use the XM Radio programming you need a XM Radio receiver, an antenna and a subscription to the XM services. Different music equipment producers have teamed up with XM Radio in order to allow adding XM broadcasting to their already existing devices. Some vehicle manufacturers are also offering XM Radio as a factory installed option.

Satellite radio quality and content

There are two important characteristics that recommend satellite radio as a service most people would like to have in their vehicles or homes: quality and content. When talking about quality we mostly refer to how clear the sound output is from satellite radio when compare to terrestrial radio broadcasts. Content, on the other hand, refers to the quality of the transited material. This is where the two giants in the satellite radio industry – Sirius and XM Radio – battle it out. The quality of the receivers and the technologies they both use are similar, but the difference can be made when it comes to exclusive high quality content. Let’s have a look at both the satellite radio quality and content characteristics:

Broadcasting quality

The broadcast quality is, when put in numbers, of 128kb/s 44.1khz for both digital radio service providers. This is the equivalent of CD quality. Although the coverage of satellite radio, which is far superior to what any terrestrial radio station can deliver, is an important factor, the quality of the sound is what brought Sirius and XM Radio more subscribers. There are many similarities to the way digital television worked or how cable TV has over 80% of the US population as subscribers, although they can receive free programming using UHF and VHF antennas. It’s the same with satellite radio – although one can get free terrestrial radio, satellite radio comes at an affordable price and offer a broadcasting quality that is superior to analog radio. Also keep in mind that satellite radio is commercial free – and this is huge selling point.
The high analog-to-digital conversion quality means that there will be no sound interferences, hissing sounds and other audio disturbances characteristic to FM and AM transmissions. This is mostly obvious when listening to music on your satellite radio system. The bass is much stronger and accurate, while the high sound levels are crystal clear. There is also a stronger mid range of sounds that you will consider to be more robust and accurate than what terrestrial radio produces. Although someone with a trained ear will tell you the music quality is not exactly as good as CD quality, it is extremely close and for the largest majority of users this difference is not even noticeable.

Content

So now that we know how good the technological side of satellite radio really is, let’s have a look at how broadcasters are trying to improve the quality of the content they provide. One of the most interesting approaches was to fight for obtaining exclusivity over some transmissions. For example, negotiations have been carried out between XM Radio and MLB in order for the satellite radio provider to obtain exclusivity rights to broadcast all MLB games. In an interview to WSJ, Edison Media Research’s President Larry Rosin declared that “it is probably inevitable that baseball radio broadcasts will go to a 100% subscription model… It will happen because there’s too much money in it not to do it.” Today, around 23% of XM subscribers are signed up to receive the MLB transmissions, so there is real potential in such a venture. Of course, this would be a terrific blow against terrestrial radio and the two sides are engaged in combat while you are reading this. Of course, content quality can also be increased by having the best people in the industry work with satellite radio. Both Sirius and XM Radio know that someone who pays $300 for a receiver and $10 – $12 each month for a radio service wants to get the best content out there. Surprisingly, when it comes to music channels, the difference in content quality between satellite radio and terrestrial radio is made in one main topic – commercials (or rather, lack of commercials on satellite radio). Since most of XM Radio and Sirius channels are in-house productions and only a small percentage are retransmits of terrestrial radio, this becomes an interesting aspect to consider.

The basics of Satellite Radio

Broadcasting digital radio via satellite is not something new and concepts of doings this have been with us for a few years. From the early days of satellite radio, companies like Dish Network have offered digital audio channels as part of their programs. The breakthrough in popularity of satellite radio, however, happened just recently, when the technology became more permissive. Satellite radio was very rare on moving locations, such as boats or cars, mostly because there was the need for some expensive equipment – a tracking dish. This was a strong deterrent which kept satellite radio quite unknown by the general public. Today, however, one can receive digital audio satellite broadcasts by using a small, GPS-like antenna. This greatly increased the feasibility of the satellite radio systems and more and more vehicle owners began considering satellite radios as a good source of music and news.

The birth of satellite radio in the United States

When the U.S. Federal Communications Commission (FCC) allocated a spectrum in the “S” band (. GHz) for the broadcasting of digital radio services in no one thought the amplitude that the system would take in the future. From the initial Digital Audio Radio Service (DARS) things progressed until two companies were given licenses to broadcast digital radio in . These two were American Mobile Radio (today known as XM Satellite Radio) and CD Radio (presently called Sirius Satellite Radio). The fact that satellite radio is nationwide makes it a very attractive media channel, both for commercial and non-profit organizations. The two companies that initiated the development of satellite radio saw the huge potential it had, since it wasn’t confined by the limitations of other terrestrial broadcasters.

Benefits of using satellite radio

Here are some of the most noteworthy benefits of having a satellite radio system:

* No more geographical limitations – since the radio program is broadcast through a satellite you don’t have to switch radio stations every time you leave a certain coverage area.
* The digital quality of the satellite radio has some amazing benefits on its own. There are no noise disturbances that were traditional to FM and AM broadcasts. The transmission is crystal clear and satellite radio receives some valuable points when broadcasting quality is concerned.
* Analog radio stations simply cannot broadcast the full range of sounds available through digital satellite radio.
* Both XM Radio and Sirius Radio can be picked up on all the US territory and they are also available in some parts of Canada and Mexico.

Satellite radio technology

Each of the major satellite radio services uses its own equipment to broadcast the signal to their clients. The competition is tight and customers have to “pick sides” in order to benefit from satellite radio broadcasting. You have to choose your preferred company and purchase adequate receivers for that particular company. Both XM Radio and Sirius Radio provide their clients with different ways of receiving their services. The field where most competition takes place is in the negotiation with the major automobile manufacturers. Both XM Radio and Sirius Radio have deals with the auto industry giants in order to offer their services and equipment as optional on the car models they produce. Other partnerships were created with audio equipment manufacturers, who now offer satellite radio transceivers and matching headsets. The most recent shock in the satellite radio universe was caused by the production of portable MP player-like satellite radio receivers.

The future development of satellite radio

One of the main problems of satellite radio was addressed by the main satellite radio broadcasters. Since you need to be in the line of sight of the satellite to receive the transmission, different problems appeared with mobile satellite radio receivers, especially when different landscaping objects blocked the direct transmission. To solve this, land based devices were installed in order to eliminate the lack of direct satellite transmission. Another interesting aspect related to satellite radios is that they approached their service offers from a different perspective than traditional radio broadcasters. Instead of airing commercials they charge a subscription fee. For many people, this is actually the best alternative, since they get an almost % content broadcast (whether it’s music or talk shows) without the – minutes per hour of annoying commercials. In most cases, the monthly subscription for satellite radio is of around $.

XM versus SIRIUS

The idea of America’s biggest two satellite-radio joining forces has been up in the air for almost four years. Although XM had a year’s start, Sirius came back on the market, eventually with both companies sharing the market in half. So, what’s to choose? XM or Sirius?
First thing’s first. XM and Sirius are based on the same principle, each of them providing music, news, sports, etc. on their channels, but, every service has its ups and downs so we will try to discuss it in this present article. A careful analysis shows that XM Satellite Radio provides a total of streams, where two are premium channels (Playboy and High Voltage), twenty-one are traffic and weather based channels and nine are sport-dedicated ones. On the other hand, Sirius offers a total of streams, the premium streams not being available. Let’s take a closer look now on two – music and news – of the categories that the two major satellites are battling.

Music streams comparison

The number of music streams that both services offer is pretty much the same: on Sirius and on XM Satellite Radio but the difference is not in the number, but in the music genres that the radios offer.

Music – Decades

XM is the absolute champion in providing the music by decades because you can listen to the ’s music, service not available on Sirius. Still, you can listen to the ’s hits together with the current hits on Sirius Satellite Radio, which is an interesting feature.

Music – Country

“Ride’ em cowboy!”. Even if you’re not a cowboy, you can listen to country-related songs on both Satellites. Classic country or country hits are to be heard as well as alternative country or country mixes, the last two features being available only on Sirius Satellite Radio. Regarding the number of streams that both Satellites offer, XM offers a total of five streams and Sirius offers four, the champion in this category being XM due to the quality and the quantity of music being played.

Music – Rock

If you are looking for sex, drogs, and rock and roll, Sirius and XM Satellite Radios can only offer you rock and roll, on a number of streams on XM and streams on Sirius. The rock subgenres are to be found in a large number on the stations, overall each service being very strong in this category.

Music – Dance and Latin

If you want to boogie, you can do that on both Satellites, listening to one of the six streams provided by Sirius or four streams provided by XM. Be careful though, because you can become a clubber maniac! And if you’re strong enough, the Latin pop stream, Mexicana and tropical music streams can really drive you crazy. XM Satellite Radio as well as Sirius Satellite Radio offer three streams.

Music – Other genres

Regarding other genres, both satellites really look up to their prestige, offering hours of hours of music, from Classical to Jazz, even Urban (Sirius feature). Both stations offer high quality tunes, making it worth all the money.

News Streams Comparison

Let’s skip to another interesting topic, news. CNN, FOX, CNBC, Bloomberg, MSNBC and many more news stations are being offered for listening in different languages. The number of streams is again near-by, XM offering a number of news streams, not like Sirius, which offers .

Bottom line

It’s pretty hard to say which station is better, XM and Sirius being tied musically but in news and sports, Sirius holding the edge. To make a little joke, if you are a fan of Stern go with Sirius, if you like Q&A go XM. Anyway, it’s hard to say which one is better, but, what can I say is that both Satellites are worth paying for.

The development of digital multimedia broadcasting

Satellite radio systems are actually part of a larger group of broadcasting mediums, which specialists refer to as Digital Multimedia Broadcasting or DMB. This digital transmission system is used in order to send data to different receivers such as radios, television sets or mobile phones and PDAs. There are two different ways of using digital multimedia broadcasting – S-DMB which is broadcasting via a satellite or T-DMB which uses terrestrial emitters. The complexity of the entire digital multimedia broadcasting field is huge. Out of all the features and characteristics digital broadcasting offers, satellite radio is probably the most spectacular as it generated immense interest and triggered an intense competition between the two main satellite radio broadcasters, Sirius and XM Radio. The development of satellite radio and other forms of digital broadcasting is spectacular because it offers two main qualities that terrestrial emitters are deficient in: quality and coverage. In the case of satellite radio, for example, the sound quality from a satellite broadcast is much higher than AM or FM broadcasts, as the hissing noises and transmission disturbances are eliminated.

Technical features of digital multimedia broadcasting – overview

Whether it refers to television, satellite radio or cell phone transmissions, digital multimedia broadcasting is based on the Eureka 147 DAB standard. Digital television uses the T-DMB which is made for transmissions on frequency bands III (VHF) and L (SHF). T-DMB is an ETSI standard (TS 102 427 and TS 102 428).
T-DMB uses MPEG-4 Part 10 (H264) for the video and MPEG-4 Part 3 BSAC or HE-AAC V2 for the audio. When it comes to satellite radio, there were a few issues to be resolved by the main satellite radio broadcasters. The satellite radio receiver needs to be in the line of sight of the satellite to receive the transmission – and there is the problem of having different landscaping objects block the direct transmission. Land based devices were installed in order to eliminate the lack of direct satellite transmission. Since the wider spectrum of broadcasts has to be covered, digital multimedia broadcasting uses OFDM-4DPSK modulation and a chip of T-DMB receiver is also provided by MPEG-2 Transport Stream De-multiplexer. This helps reduce the negative effects of shadowing and fading, present in many digital transmissions.

The future of digital multimedia broadcasting

The transfer from the analog world to the digital one is obvious in all fields of work. Since digital multimedia broadcasting is developing so quickly, there is a silent battle going on between the new age digital technology and the classic analog one. OF course, many compare the transition from the analog to the completely digital era with the way audio cassettes were replaced by CDs and later on even DVDs. However, the development of digital multimedia broadcasting is slower since it happens on so many levels at the same time. Digital television is taking us into new spaces that are basically hybrids of the features of regular TV and characteristics of the Internet. Satellite radio is also taking huge leaps forward, with more and more programs having satellite radio exclusivity. There are even discussion of moving events like the MLB exclusively on satellite radio, which would provide one of the first deadly strikes against terrestrial radio broadcasting. Digital data transmission is fast and accurate, and so far reality proves that the satellites used in order to facilitate broadcasting and reliable. Most digital multimedia broadcasting companies that own satellites also have backup ones ready to go in orbit and replace a defective one. Some other benefits of digital multimedia broadcasting recommend it as a next step in the development of broadcasting. From the consumer’s point of view, the quality and interactivity options of digital TV or satellite radio broadcasts are important features. Although most digital multimedia broadcasting channels and technologies are still complex and sometimes expensive, the evolution of digital broadcasting seems to be here to stay.

Sirius Satellite Radio overview

Together with XM Radio, Sirius Satellite Radio is one of the two main providers of digital radio broadcasting in the United States. Sirius Satellite Radio currently broadcasts on over channels with a variety of broadcasts including music, talk shows, news broadcasts and different other forms of audio entertainment. Sirius Satellite Radio covers the entire US territory. The high quality of the broadcasting signal produced by using the most advanced digital encoding technology makes the transmission clear and accurate. The fidelity of the sound transmitted digitally is much better than any analog radio provider can offer. The noise disturbances often associated to FM and AM broadcasts are now eliminated and the transmission is clear and almost identical in quality with the original track. Sirius Satellite Radio holds one of the two FCC approved licenses for delivering digital radio in the United States. The digital radio broadcaster only shares the field of Satellite Digital Audio Radio Services (SDARS) with Sirius XM Satellite Radio Inc. Here is some more information on the Sirius company:
Corporate headquarters: New York City, New York
Date of launch: July ,
Satellites in service:
Available satellite radio channels:
Monthly subscription cost:$.
Sirius Satellite Radio is truly an impressive corporation. Located in the heart of New York City with a huge recording studio situated in the Rockefeller Center, Sirius Satellite Radio has a huge library of over million music tracks. The quality of the transmission is very high as it is in the kb/sec format – which is similar to CD audio quality. The company uses digitized signals through the PAC encoding technology, providing high fidelity broadcasts all over the United States.

The Sirius satellite

The three Loral SS/L- commercial satellites used by Sirius deliver constant digital radio broadcasting to Sirius’ subscribers. As with most commercial satellites, the Loral SS/L-s orbit above the Earth at miles. Very similar to XMs satellites, the Loral SS/L- commercial satellites have a more inclined orbit which allows them to cover an even more extended area. The elevation angle of degrees is more generous than the regular degrees used by geostationary satellites. Since one of the most problematic aspects of satellite radio broadcasting is the line of sight – which can be easily interrupted by landscape or buildings – the Loral SS/L- commercial satellites have a slight advantage over their competitors, since they have a clearer line of sight. The three satellites used for broadcasting slowly orbit around the Earth and only two of them are functional at any time. This is because Sirius only has two transmission frequencies and by alternating satellite transmission they can eliminate interferences while also having a spare satellite to put to use in case something goes wrong with one of the others. The satelites take turns broadcasting – when one of them leaves the footprint of the continental U.S. another picks up the broadcasting transmission. Since the more inclined orbit provides better coverage, Canada and Mexico are also well covered by the digital broadcasting. This is an interesting feature of the Sirius satellite radio, as it enhances the benefit of not having to switch radio stations during long trips or while traveling outside US borders. Sirius has also announced a collaboration with the Canadian Broadcasting Corporation and Standard Radio Inc. This would allow anyone in Canada to benefit from Sirius’ services while using any of the Canadian English and French channels.

Sirius broadcasting

Because the broadcast signal used in satellite radio transmission is so strong, you only need a small receiver in order to be able to listen to it. By using small omni-directional antennas you can take your digital radio programs wherever you are – either on the road or at home. The technology used is similar to GPS devices and the receivers don’t require pointing. Some of the new features of satellite radio refer to the extended broadcast information abilities, and the transmission can supply information on artist, music title or genre. One of the developments Sirius is working on is streaming video broadcasting – something that will probably become available to the general public soon after the technology and broadcasting methods become secure enough.

What is satellite radio

Satellite radio is often considered one of the biggest improvements in broadcasting since the introduction of the FM band. Satellite radio is also called subscription radio or pay-radio because it is only available trough subscription to one of the satellite radio providing companies. Satellite radio follows a concept similar to cable television by providing a very wide range of programs which are not available in the traditional FM or AM format for a fee.

Satellite radio uses satellites to deliver radio programs to subscribers. The radio signal is broadcasted from Earth based stations to communicational satellites, which then redirect the signal to satellite radio receivers. The radio signal is broadcasted by communication satellites to a much larger area than traditional terrestrial radio antennas. For example, satellite radio is available al across the continental area of the United States. Satellite radio is available now in most parts of the world trough services provided by companies like WorldSpace (in Europe, Asia and Africa), Sirius and XM Radio (in North America). The radio signal you receive using satellite radio is digital, which means that it is always clear and static-free, which is one of the great advantages of satellite radio. Another great thing about satellite radio is that it is almost completely commercial-free.

To begin listening to satellite radio you will need the actual satellite radio (also known as tuner or receiver), a satellite radio antenna (which is often incorporated in the satellite radio) and a subscription to the service you choose. There are several types of satellite radio from which you can choose. One of them is the dedicated car or home radio, which play trough your car or home stereo. A second option is the plug-and-play radio, which can be used in your car, as well as in your home by paying a single subscription. Your third option is the portable radio, which has rechargeable battery, a built-in antenna and you can listen to it wherever you go using headphones. The radio signals offered by different satellite radio companies are proprietary, which means that you will need different hardware for receiving, decoding and playback, depending on your subscription. Each satellite radio receiver has its own serial number called Radio ID. When you get your subscription, you will also get an activation code for your receiver. Besides the actual radio programs, satellite radio transmits metadata that contains the name of the artist, the title of the song or program, as well as the name of the channel. This makes it easier for you to decide which channel to listen to and which program to choose.

Satellite radio services provide the subscriber with more than 100 programs that vary in content from rock and jazz to rap and classical music. But satellite radio’s utility reaches far beyond listening to your favorite music without the interruption of those annoying commercials. Satellite radio also offers exclusive sports programs, cultural and educational shows, news and talk-shows. Some of the celebrities that have moved their shows from free radio to satellite radio include Howard Stern, Opie and Anthony, Bob Edwards and Martha Stewart. Unlike terrestrial radio, satellite radio is not affected by bad weather or even calamities.

At first, many people wondered why they should pay for radio if they can get it free. However, satellite radio attracts more and more people every year due to its great advantages: no commercials, extensive reach, theme programs and exceptional quality of sound.

The technology behind satellite radio

Any song you hear on satellite radio stars as a recording in a specific format on different recording mediums. IN most cases, the recording quality has to be maintained fairly high, usually around 384kb/s, while also being reasonably small enough to be transported on CDs and DVDs. The music tracks used in satellite radio are cataloged using a similar system to the MP3 cataloging criteria, the ID3 tags. The choice for the music tracks that will be played is made by each channel individually. The DJ selecting the tracks usually chooses about 20-30 minutes worth of music. The DJ has to listen to the tracks to make sure they are in proper condition and then simply lets the computer decode the original file. The same thing is repeated once the initial 20-30 minutes are exhausted and the music playing cycle repeats itself.

Sound encoding in satellite radio

Encoding is one of the key elements of digital radio. Each channel is handled by a different encoder. The encoder basically takes the analog file and turns it into a digital one. The digitalization process is made in real time and the music files are transformed into 1′s and 0′s. This process is carried out by powerful computers that analyze sound waves and frequency and break them into binary code. The encoding process is carried out at 128kb/s, 44.1Kh which is actually CD quality. After the song is encoded, it is transmitted to a multiplexer where other channels are also present – the multiplexer basically takes all the channels of the satellite radio provider and combines them into a single broadcast transmission. The data is then sent to a satellite modem device which modulates the data and sends it to the broadcaster’s satellites, using unique transmission frequencies.
What happens above the Earth
Here is where the satellites are located. They receive the transmission and transmit it to the receivers we have in our homes and cars. The satellites are located at 23,000 miles above us – both Sirius and XM Radio use satellites located at this distance from the Earth. The satellites are located in geo-sync, which means that hey orbit above the location they are designated to service at all times. When the satellite receives the transmission encoded at 128kb/s, 44.1 khz it rebroadcasts it to the geographical area it covers. Both Sirius and XM Radio use satellites that cover certain areas of the United states – mostly the East and West coasts. For example, one of XM Radio’s satellites covers the western part of USA, probably an area located roughly from Seattle to San Diego on the West and Minneapolis to Houston on the east. The increased sound quality is possible because the broadcasted data (music tracks, news, sports transmission) don’t get sliced up too many times in the decoding process.

The antenna

The antenna connected to your satellite radio receiver picks up the transmission on L-Band. The recent technological advances have allowed digital radio broadcasters to create receivers small enough to fit mobile locations. In the early days of satellite radio, a large parabolic dish would have to be mounted on the car in order to receive signal. Also, before the more compact receivers were created, the early satellite radio receivers needed electronic movements that directed the dish towards the satellite line of sight. Modern flat panel receivers have eliminated all the problems of their predecessors and can be fitted almost anywhere without taking up too much space.
The receiver and the output
The receiver is the device that decodes the data, basically doing the exact opposite of what the encoding process was like. After receiving the signal from the antenna it amplifies it and converts it to usable sound. The car or home audio system is then able to play the selected satellite radio channel. The rest of the process is exactly like analog broadcasts would work, with an amplifier and speakers outputting the sound.

Sirius and XM Satellite Radios

There are two major companies that offer satellite radio in America: Sirius and XM.
XM was the first company that offered satellite radio. It has two satellites named Rock and Roll and it has its studios in Washington D.C. Sirius Radio has three satellites and has its studios in New York As the XM was first, it has 3,2 hundred thousand, but Sirius brings competition with 1,1 hundred thousand subscribers in the present time.

Satellite radio is by far the best radio ever, making the AM/FM radios look old and dying even. This new era of radio has a lot of advantages that will please you at the maximum.
As the income comes from the subscribers not from advertisements, there are no commercials, no one is saying what to buy, no one is promoting their channel and no one is interrupting you from listening to what you want, where you want. There a lot of choices in want to listen to as both XM and Sirius have a big programming variety that includes music channels of world music(pop, rock, classical, rap, hip-hop, opera, country, western, jazz, dance, blues, Latin), weather, news, traffic, sports and entertainment channels. Local weather and traffic channels are available only for major cities in the U.S.A. provided by the two companies and every five minutes you can hear updates. The best thing in all channels is that there are uncensored. So, you can listen to uncensored stand-up comedy and hip-hop channels, at least for now.

The satellite radio has a very good sound quality, no static and no interference, a quality that may be compared with the one of a CD. The radio is based on a go/no-go system based on the strength of the signal. So, weak signal may cause dropouts.
You can easily get information about songs and artists right on you satellite radio receiver that can also help you select channels and categories. This makes it easier for you to choose the exact channel or song you want to hear. So, whenever you are wondering what song or channel you are listening to just read the information that the receiver shows.

Now you can get satellite radio wherever you like, eventough at first it was design only for car use. With the right equipment you can easily have radio, but it depends on you whether you subscribe at XM or Sirius. Unfortunately, you can’t use a satellite radio turner for both XM and Sirius. There are three types of turners depending on where you want to listen to satellite radio. The Plug-and-play turner can be used out-door wherever you like as long as you have a portable boombox that can receive the signal. There are turners especially made for using them in cars and the home satellite radio turners for using them at home.

Both companies want now to offer a video service. This is planned to happen in the second half of the year 2006 and will include at first two video programs designed for children. Satellite radios’ prices start at about $75.A subscription costs 12.95 per month wherever you want to subscribe as both XM and Sirius radio charges the same. There a couple of discounts like you can get satellite radio for a year at $9.95/month or Sirius is offering a subscription for a lifetime at $500.

SONY portable receiver

Welcome to the world of Sony! In this article we will try to discuss the features of the Sony portable XM receiver, which, by the way, was the first plug-and-play model sold on the market. The gadget is the ideal receiver for people who need a compact and totally portable communications receiver. Although the user interface is pretty out-of-date and the receiver lacks a numeric keypad, the Sony portable receiver is a great radio. Imagine yourself in a James Bond movie, or imagine the good old days, the ’s, imagine a spaceship with its fine curves, well.. the Sony receiver has it all: the futuristic looks of a spaceship, its utility like any Bond gadget and its state-of-art like the science fiction of the ’s movies. The XM Satellite Radio is an adventure! Although the portable receiver is no longer listed on the market, it is still available in the channel. Below, I will try to discuss the features of three Sony portable receiver models, the ICFSWG.CE, the ICFSWS.CE and the ICFSWS.CE.

ICFSWG.CE Sony Portable Receiver

The price of this model varies at around $, its frequencies being kHz -Mhz (LW/MW/SW), – Mhz (FM). It has memory presets, an audio output of mW, size of x.x mm and the weight of g.
The nice thing about this model is that it provides LCD read-out in kHz steps, can be electronically tuned and the frequency can be adjusted on the keyboard. For its modes (AM, SSB, FM) you can listen to stations from all around the world. As additional features, you can use the receiver as a clock or alarm.

ICFSWS.CE

For $, this model is a bargain. It has a led tuning indicator, frequencies between – kHz (LW), – kHz (MW), – Mhz (FM), audio output of mW, size of xx mm and it weights g. As a drawback on this model is that you can listen to FM stereo only throughout the headphones.

ICFSWS.CE

Last but not least, Sony is offering a world receiver that is a handy companion for people who travel a lot. It has twin digital clock display and clock controls, telescopic whip, and the unit closes itself when not in use. Regarding technical details, the ICFSWS.CE portable receiver cathes frequencies between – kHz (MW), – Mhz (SW), – Mhz (FM), it has dial tunning, Led tunning indicator, an audio output of mW, size of x.x. mm and weighs g. The average price is $.

As for car kits and accessories, home kits are available at an average price of $, the package containing a home dock, a power supply, an antenna, and an adaptor between mini-stereo to twin RCA. If you want to purchase a car kit, you can found one at a price of $.. Although it’s hard to find one, you can purchase a FM Modulator, if you don’t have a car radio with a cassette player. Also, for $. you can buy ft. cable extension, which connects to your home antenna, providing more cable, thus, more space.
