Essential Sirius Satellite Radio Accessories and You
Music is a part of life, and everybody wants some music at one point or another. This is where Sirius radios come in. They provide quality music 24/7. Oftentimes, the initial reaction of Sirius radio owners is to find the perfect Sirius satellite radio accessories for their new gadget. Since Sirius satellite radios are in themselves very splendid, it is only natural that you would want to seek a companion for this lovely tool. And with its accessories available in the market, you will need a guide to get what only is essential and not to overspend.
Sirius satellite radio accessory ranges from indoor/outdoor antenna, remote controls, car kits, and many others. The remote controls have an astounding LCD which displays the songs that are currently being played. But before you buy something, think carefully and logically. Do you really need a remote control for your radio? Will you be listening mainly on the road or in the premises of your home? If it is just something that you want for the sake of looking flashy, then it would be wise to move on with more important purchases.
For those who have low reception on their areas, the perfect Sirius satellite radio accessories would be comprised of an outdoor/indoor antenna and other paraphernalia to make the signal better. Having an antenna at the south end of your home is ideal to get a good reception. If you have a choppy reception, you will not be able to lean back and relax to the soothing music your Sirius satellite radio can give you. So by buying an antenna, you'll be solving this problem.
Sometimes though buying an antenna is not really a necessity. Place the radio on the south wall of your house, and check the reception. If it gives high reception, then you will not have to buy an antenna. But if it is low, then you'll have to invest on one. There are weather proof antennas which will stay snug and in perfect condition in every season. This type of Sirius satellite radio accessories would cost around $40 to $80, so check your area first before heading to the store to purchase this.
When it comes to Sirius satellite radio accessories, people should have docking stations which will enable you to connect the radio in your car sound system or home stereo system. This will make you enjoy the music better, since the bass and all the other elements would be able to showcase their whole pitches. Then again, there are Sirius satellite radio accessories in the form of docking stations with speakers. This will be very portable, and it will have a magnificent sound quality. For the price of $30 to $90, the output would be worth every penny.
Music is best heard in the air, not confined to your ears in the form of earphones. You cannot listen too loudly in earphones because your eardrums might pop, so in terms of Sirius satellite radio accessories, you can never go wrong with a docking station.
Satellite Radio Technology
Satellite radio technology is the equivalent of cable or satellite television and it is definitely here to stay. There are several reasons for this: the quality of the broadcasts is higher, the quality of the apparatus's reception is higher and the general coverage of the channel, that is to say the so-called satellite's footprint is far greater as well.
This has the effect that if you travel long distances, you will be able to stay with the same channel without having to look for a new one every forty or fifty miles as you have to do with AM or FM radio stations.
In order to reach this quality, the recording and playback speed needs to be around the 384 kbps level. The music tracks are catalogued in a comparable way to the MP3 system, which uses names called ID3 tags.
Each station on satellite radio attempts to create its own identity. A music station may try this by playing music only of one type or from only one era or decade. This means that you may get a satellite radio station called 1970's Punk music or Twentieth Century Classical Music.
On some channels, the music controller or disc jockey will choose, say, fifty minutes worth of music, will listen to it in order to determine that the quality and the order are correct and then let the computer play it over the airwaves. This allows ten minutes every hour for the news and then the sequence can be repeated automatically.
Satellite transmission uses digital recordings and each station is encoded on a different frequency. Similarly, each decoder, say, in your car or your home needs to recognize and decode each channel separately too. This coding and decoding is done extremely quickly, in fact in what is called 'real time'.
The resulting binary or digital code is then translated into analogue signals so that your speakers can replay it. This process produces sound which is just about of CD quality.
The transmitting satellites are in a geo-static orbit at 23,000 miles above the equator and have a large footprint which is the name given to the area of ground that is capable of receiving their broadcasts.
In America, for instance, the two areas concentrated on at first were the densely populated east and west coasts in order to maximize possible income. One satellite would be incapable of covering the entirety of the United States in that orbit.
In order to receive satellite transmissions, you will have to use a special antenna on your decoder. This antenna must be capable of receiving L-band broadcasts for it to be of use.
These new antennas are a huge improvement on the parabolic dishes (similar to those used for satellite television) that one used to have to have in order to take advantage of satellite radio technology.

Info on the Latest Stats For Internet Radio
Internet radio is audio broadcasting that's transmitted via the internet. There are several internet radio stations that are associated with traditional radio stations or networks, as well as a number of internet-only radio stations.
According to an article in the tech section of the Wall Street Journal in November of 2009, the distinction between online and traditional radio stations is beginning to melt away. This has led to increasing competition in online radio and the emergence of more innovative forms of radio. Furthermore, wireless internet radio devices and smart phone applications are encouraging more people to listen to online radio.
Internet radio is particularly popular with expatriates and those who don't have access to local stations that suit their interests. Internet stations are accessible from just about anywhere in the world, and services offered include a variety of musical genres, sports, news, talk, and any other radio format heard on traditional stations.
According to a 2008 survey, 13% of Americans listen to internet radio, and that percentage continues to increase. Unlike traditional radio stations, radio stations offer more than just a passive listening experience. For example, on crowd-sourced online radio stations, listeners can vote songs up or down to shape play lists.
Advertising Opportunities
Internet radio provides businesses with an abundance of advertising opportunities because it attracts a higher income audience and listeners of various ages from around the world. Furthermore, according to statistics, internet radio listeners are highly loyal. The majority of them visit their favorite online stations at least once a week. In order to make your sales messages stand out in the minds of frequent listeners, it's recommended to hire a professional voice talent who can create convincing, memorable voiceovers that reinforce your company's brand image.
The Importance of Compelling Station Imaging
In order to attract listeners to your online radio station in the first place, it's essential to have radio imaging that makes a lasting impression. The choice between a female radio voice and a male radio voice for your station imaging will largely depend on your target audience and the type of content your station primarily delivers.
Hire a professional voice talent to deliver promotions, station IDs, and other kinds of radio imaging to set your station apart from the competition. Internet radio is saturated, so it will take some innovation, creativity, and exceptional voice over talent to get your station noticed.
Satellite Radio - The SIRIUS XM Entertainment Lineup
Those people who subscribe to Sirius XM Radio don't want to do without it, so the majority considers the merger a good thing. The FCC looked at this merger carefully due to its smacking of a monopoly, but without this merger both companies may have slowly circled the drain forever, operating in the red and reducing their program before disappearing into the bankruptcy courts and having to deal with unhappy customers.
Instead, they combined forces under the old "united we stand" mantra and many don't think the programming has suffered. Yes, you may have to find your favorites again, as many genres changed station locations, but all in all, the lineup is still comprehensive and has something for everyone. Here is the lineup under the 'entertainment' category, which includes shock radio, adult radio and comedy.

Why Satellite Radio Is So Popular
The current entertainment world is awash with ways of and goods for using up our free time and at the same time filling our brains with mindless trivia and advertising junk messages. In between the programmes and the music, the message is 'buy, buy, buy; from me, me, me'. This is one of the reasons why satellite radio has become so popular, but I will expand on that later.
One of the main reasons why people like satellite radio is because if you travel quite long distances, you do not keep going out of range of the station it took you ten minutes to find and search for another one.
Satellite radio stations have a tendency to have a large to very large footprint. In other words, you ought to be able to keep listening to the same station if you want without constantly retuning.
Not only that, but satellite radio is invariably digital in nature which means that the signal will be better and the resulting sound quality will be far better too. This means that the background noise that we have been conventionally used to has practically disappeared.
The sound from a good piece of digital stereo apparatus is second to none. In reality an AF /FM radio cannot hold a candle to a satellite broadcasting station.
The cost of satellite broadcasting gear has dropped dramatically, which has increased its public awareness and uptake, which in turn has increased sales and allowed the price to plummet further. Nowadays, a satellite radio receiver is as cheap as chips.
Not only that, but in the early days, in the Seventies and Eighties, parabolic dishes had to be extremely focused. They had to be focused on the satellite as a satellite TV dish still has to be now, but a radio system does not need to be so accurate anymore, which permits them to be used in cars and boats.
If you get tired of the adverts that constantly drone out of terrestrial radio at you, it can be a good idea to find a satellite broadcasting channel that suits you and subscribe to it. For $10-12 a month, you will get the type of programming that you like without all the ads!. Isn't that wonderful?
As with all forms of entertainment, at the end of the day it is up to the end user to choose whether the cost of satellite radio is justified, but one thing is for sure, satellite radio increases one's choices.
If you are fed up with the present range of radio stations in your area then the thousands of extra, frequently world-wide stations available to you on satellite radio may be just the thing that you are looking for, especially if you are looking for a station in a foreign language that is not covered in your neighbourhood.
Grace Digital Internet Radio Review
There are many choices out there today when it comes to the internet radio industry, and there are even more choices if you throw satellite radio in the mix.
First of all, if you are still hanging on to satellite as a legitimate choice; throw it out the window, internet radio is your best bet. Second off, if you haven't read through any of the new Grace digital internet radio reviews then you are behind on your research, and you may want to take some time out to do so before shelling out a couple hundred bucks. The Grace GDI-IRA500 Wifi Radio is available now for under $100 and offers a great set of features.
The only real way to find out about what the best radio is on the market is to check out real customer reviews. This can save you hundreds of dollars in the long run so be a smart consumer and check out a couple review sites before purchasing any item. The winner on the most popular sites out there is the Grace Digital Radio. It offers all the quality of the top brand radios out there but doesn't break the bank in the process. This is especially true in these hard economic times that we live in. Any penny saved is a good thing and even better if you are not sacrificing quality.
The Grace digital internet radio offers the consumer the quality that they are looking for, but without the big brand name price tag that comes along with similar items. Radio on the internet is the radio of the future regardless of what the people on satellite radio may tell you, because radio was meant to be free and the internet will keep it that way.

Playboy Satellite Radio
Satellite radio has really taken off in some parts of the world, particularly in countries with a huge land mass. Places like the USA, Canada, Europe and Australia, places where it is hard to realize national coverage with traditional land-based radio broadcasting without hundreds of expensive sub-stations to amplify the signal.
Yes, without a shadow of a doubt, satellite radio is here to stay for several reasons. First of all, satellite radio is digital and therefore is able to produce sound of extremely high quality. Terrestrial digital radio can do that too, you could say.
Yes, that is correct, but the coverage of terrestrial digital radio is rather small which means that if you are driving a long distance, you will have to keep retuning your radio to a new station, whereas with satellite, the footprint can cover thousands of square miles.
A lot of new satellite radio channels are springing up all the time. It appears that everyone wants to get their hands on this new marvel of wide-area coverage at a cheaper rate than it used to cost to cover a county. And why not? The advertising potential is quite fantastic compared to the old fashioned local AM or FM radio stations. Radio has now gone countrywide.
Playboy Satellite radio is one of those companies that has realized the potential of satellite radio and established its own channel with a large footprint. It was launched in March 2006 on the Sirius network by Christie Hefner and now boasts over one million subscribers, which is a truly remarkable figure. There have probably never before been a million opt-in subscribers to any radio network channel ever in history before.
What makes this number of one million subscribers even more striking is that the Playboy satellite radio channel is not part of a package or a bundle of other channels. No, people have to voluntarily phone up or go to the Playboy website and request membership in person, that is to say that it costs time and effort to sign up and one million people thought that it was worth it.
Something else that is unusual is that the Playboy brand is connected with visual material - naked ladies, in fact - and radio is well-known for not being very good at visual representation. It is obvious that no radio station is going to make much headway in the market place with nudity as a trump card.
So what is happening here? Well, the fact is that no-one is really completely sure. You have to subscribe, but it is free at the moment. It is also true that the Playboy brand name is considered cool and distinctive among a certain echelon of society, but will that be enough to keep people tuned in? Only time will tell.
The answer probably lies in the fact that it is free and that it can be listened to over a considerable area, but they cannot be the only causes. There is probably a novelty value too and the quality of the programmes will have to be high as well.
The Internet Radio Tuner: How Much Should You Pay?
Ten years ago it was digital HD radio, two years ago it was satellite radio, now it's the internet radio tuner that is making waves in the tech industry. You see satellite radio is great and has no commercials, but they charge a monthly fee if you want to use their service. Well with an internet radio tuner you get all your favorite stations, but it doesn't cost you a dime after the initial purchase price. It offers the quality and the constant music that many consumers crave,but doesn't have the hefty recurring price tag that comes with satellite.
So the question is: how much should you pay? Most internet radio tuners cost between one hundred fifty and three hundred dollars. You can find a very nice one for a couple hundred dollars and a little bit of good consumer research. Reading customer reviews and searching the internet for a price is the best way to save money on any item; especially something technology related like a radio. There are hundreds of options to choose from, but reading through reviews and looking around will help you narrow down the field rather quickly, and you may be surprised to find out that just because an item is more expensive doesn't necessarily mean that the item is of better quality. If you are spending over three hundred dollars on an internet radio tuner; you are spending far too much. The best tuners for your money are in the two hundred to two hundred and fifty dollar range.

Think Aircraft Communication Radios, Think Icom!!!
What Is Satellite Radio?
Satellite radio has in fact been around for quite some time, but it was inaccessible to most people because the stations that were broadcasting were fairly obscure, the apparatus was costly and the antennas, usually in the form of dishes were highly directional, which meant you had to use expensive, experienced installers.
For proof of this you should look no further than bookmakers and betting shops who needed specialized satellite broadcasts beamed to their establishments with the results of the races live.
The difference now is in price and the power of the satellite radio transmission units as well as the receivers. In other words, satellite radio technology has progressed a long way since the Eighties. Satellite radio can also be received more easily nowadays, although the reception of satellite TV broadcasts still requires a directional receiving dish. This is why satellite TV cannot be received well on a boat or in a car, but you can still get satellite radio and you can still operate your mobile phone.
Satellite radio broadcasts are digital so most of the advantages of using it are linked with digital technology. Some of these are: the ability to pick up signals from all around the wold through the satellite network and the loss off interference - that annoying hiss that you often got at night while listening to a distant broadcast. Reception is now consistently crystal clear due to the simple rythym that is digital - on and off or high and low.
Digital only makes use of two signals so they are not possible to mix up, whereas analogue had millions of them allowing for mistakes due to bad weather or / and bad equipment. That has been largely eradicated.
The state of affairs in the US is that there is still competition between two opposing systems: XM and Sirius and it is to be hoped that this situation will soon be settled as it was thirty years ago between VHS and Betamax, because otherwise it will only be the customers who lose out in the end - the clients of the company that goes through.
There were originally problems with satellite radio in some areas because natural or man-made structures would block the line of sight from the antenna or dish to the satellite causing a break in transmission. Typical reasons for this would be tunnels, mountains and sky scrapers.
However, the satellite radio service providers soon came up with a resolution to the problem by bouncing the signal from the space satellite off terrestrial dishes, in other words, reflecting them at closer to ground level, thereby providing satellite radio to millions of inner city dwellers.

Radio Transmitter - Selection
In case you do not have a good transmitter, you will never be able to get the best out of your satellite radio. There are two major service providers of radio and your transmitter must be capable of getting the quality signals of the satellite radio supplier. The radio transmitters are widely utilized by people all over the world. They are getting more famous every day because they are extremely useful devices. The main thing you must remember is to select the perfect radio transmitter that suits your requirements. You will be extremely frustrated if you bought a wrong one.
In case you are looking for the radio receiver, first of all you must check and search for the famous brands that are providing these systems to the customers. In this way you will be sure that the system is of very high quality. Never buy the non branded systems as you never know they might not work properly.
Now decide the kind of receiver you are looking to buy. You have to think whether you require an antenna for your house, vehicle or ship. In case you want to buy receiver for your house then buy the one that can be attached to your TV and tape recorder. This will involve outside brackets and abundance of cable. A correctly installed, excellent transmitter can increase the signal level significantly. So you need to be very careful in selection so as to choose the one best for you.
In case you are looking to get a transmitter for your vehicle then there are number of satellite systems available for you in the market. If you want to install a satellite radio transmitter for your ship then do not worry as you can easily find the systems that are best for the ships. You can get high quality signals without any kind of problems on your ship as well. The systems made for the marines are highly effective. The only problem regarding the ship radio transmitter is that there are not many systems available in the market when compared to car and house systems. If you are facing signal problems inside your house, car or inside the ship then do not worry and buy radio transmitters to improve the signal level. I can assure you that once you will install and use this device, you will be completely satisfied and pleased with its service.

Is the JVC KT - SR2000 Satellite Radio Any Good?
Satellite radio is an amazing advancement in radio technology. With the content allowed and the clarity you can receive from all areas of the globe, life is made infinitely simpler. Among the forerunners of the trend is JVC satellite radio. One of the best radios of this brand is the KT-SR2000 Plug 'n' Play Sirius Satellite Radio Receiver. Personally I just recently purchased one and I am ecstatic with it.
It is extremely small, fits inside my pocket and has a super bright and readable screen. It has a reputation of having an excellent antenna. I installed the JVC radio in my car with the antenna on the dash and I experienced very few drop outs even though I was in unfavorable antenna locations. I did have a hiss with the integral FM modulator, so I decided to switch to direct connection with my MP3 auxiliary input on my car stereo, which rendered nearly perfect sound.
The screen really is great and is readable even in bright sunlight. This unit comes with a suction cup mount, which is a whole lot better than the double sided tape that other brands use. This is a really big plus since sometimes I have to drive my car in places where breaking into cars is not uncommon, this way I can store my radio in a glove box. I am enjoying my favorite music genres with Sirius Radio as well as the extensive news services they provide.
With this product working so well for me I have to say that JVC satellite radios are top of the line in performance and quality. JVC has nowhere to go but up and if you look at the reviews about the product you will see just how well these things perform. They also have an amazing customer support hot-line that you can feel free to call anytime day or night. With all of these features you would have to be crazy not to purchase one of these devices.
Honestly the greatest thing about my JVC portable Sirius Satellite Radio is that I can take it with me in any car that I choose to ride in, I can also have the device playing at my house and it will play on every radio inside my house and backyard. This device is truly magnificent, whether I am going on long car trips with the family or I'm grilling in the back yard, I know that the sound quality will be excellent.

Internet Radio Receiver: It Would Be a Huge Mistake to Go With Satellite Radio
Everybody who watches the news or goes on the internet today knows about the new WiFi radio craze. It is one of the most useful things a man or woman can have. Most WiFi radio stations use internet radio receivers to broadcast there signals, and best of all most of the time it is completely commercial free. Just like satellite radio you need an internet radio receiver if you want to pick up the signal, but unlike satellite radio it doesn't cost you monthly.
So no commercials and no monthly fee hmm sounds like an absolute no brainer. It is a wonder that more people aren't taking advantage of this new technology, and would rather pay for a satellite radio every month. What a complete rip off, and satellite radio is only limited to a certain amount of channels.
When you go with WiFi based radio or internet radio the only investment that you are personally making is in the receiver itself no monthly fees or dumb access codes that you have to input. As long as you are in a WiFi hotspot then you are good to go. Some people will balk at this and say that WiFi hot spots aren't everywhere so you would constantly lose your signal in the car. Incorrect, some major cities are making their whole cities WiFi hotspots, and with the recent invention of the portable hotspot, there are no limits to your internet radio usage after you make the initial investment of the internet radio receiver.

Optical Fiber Systems in Long Range Radio Communication
Optical fiber systems are great importance in the long-range radio communication scenario. The optical fiber technology has greatly improved in the recent times. It is in fact one among the most recent technologies that is being use in the communication front. The superiority of the technology has been instrumental in the innovations in the filed of communication. The usage of the technology in telecommunication systems, data systems and cable television transmission has greatly contributed to the efficiency factor of these areas.
The scientific application and engineering of optical strands is the basic idea behind the systems. The data is transmitted in the form of light rays in the optical fiber equipments. Considering the speed of light, the speed of data transmission can be estimated. The high speed of data transmission has greatly contributed in quick and effective communication in various fields. The technology known as 'total internal reflection' is being used in this technology. The light signals are contained inside the core of the thread and this makes the system more efficient than the other systems. The data signals tend to diminish in other systems. This is the reason why it is used n long distance data transmission. The higher spend compared to the conventional techniques is also among the reasons for its usage in the long distance data transmission.
Structure of Optical Cables
Many different types of optical cables are used in the communication scenario now. A basic optical; cable has two layers. The center part of the strand is known as the core. The signals in the form of light rays travel through the core of the strand. The protective shield outside the core is known as cladding.
The cladding has to major functions. The main function is protecting the core from extreme interferences. Cladding also serves as the internal reflective boundary that enables total internal reflection. It is also the key factor as it enables the signals to travel towards the right direction towards destination.
Advantages of the System
Compared to the traditional data transmission techniques, the optical fiber technology offers many advantages. The considerable reduction in the signal loss is one among the most important advantage offered by the technology. Optical threads are also immune to the electromagnetic interference that is common with the traditional metal wire transmissions. There is also a considerable increase in the data transferred through the system. The great technology used in the components also ensures the quality of communication.
The technology also makes use of lower weight equipments and components reducing the transportation cost and handling cost. Enhanced security and higher performance are the two major aspects of this system. Lack of radiation is also among the factors that make the technology popular.
Optical strands will not produce sparks making it a safer technology when compared to the conventional techniques. Protective qualities of the cladding contribute greatly to the safety aspect. Cost effectiveness of the system also makes it a safe choice to make.
However, long distance radio communication has been greatly benefited with the introduction of this technology.
Satellite Radio - It's Radio Your Way
If you've ever wondered what would make pay radio worthwhile when "regular" radio is available for free, here's the answer: it's radio YOUR way. Satellite radio gives you the programming you want to hear, the way you want to hear it, no matter where you are.
Commercial Free
One of the biggest advantages of pay radio is that since it's a subscription-based service that is supported by listeners rather than advertisers, it's commercial free.
Lots of Programs to Choose From - Uncensored and Uncut!
Pay radio services offer hundreds of programs in every genre, including music, talk, sports, news, and comedy. And because they're subscription-based services rather than FCC licensed services, programming is not subject to the same regulatory scrutiny as regular radio. This means that shows that would be strictly censored on regular radio can be presented whole and uncut.
Outstanding Sound Quality
Crystal clear sound quality is one of the hallmarks of satellite radio. And since the radio signal is digital, static is a thing of the past and signal strength isn't geographically limited. You can enjoy your favorite programs no matter where you are, with no degradation of sound quality.
Programming Info Available
Ever hear a great song on the radio, but can't find out who the artist is? Or have you ever tuned into the tail end of a super talk show, only to have it go off the air before you can find out the name, time slot, or schedule so you can tune in again? Satellite radio tuners eliminate those annoyances by displaying comprehensive information about whatever is playing.
Local Traffic and Weather Wherever You Are
Satellite radio programs also offer round-the-clock information about local traffic and weather conditions. This can be a major timesaver for travelers, commuters, or anyone who spends a lot of time of the road. An addition, if for any reason terrestrial radio stations are off the air, you can always count on getting accurate information from digital radio.
Wide Range of Affordable Subscription Options
Digital radio is very affordable, with a wide range of programming packages that let you pay for exactly the services you want and need. At the low end, "pick your programs" packages are available for less than $7 a month, and comprehensive packages that offer more than 160 programs come in at well under $20 per month. There are even packages that offer programming from both of the nation's satellite radio powerhouses, Sirius and XM.
Enjoy Your Favorite Programs Everywhere You Go
Satellite radio is great at home, but it's invaluable for anyone who spends time on the road. Unlike terrestrial radio, the satellite radio signal is not limited by geography, so you can hear the same programs with the same commercial-free convenience and outstanding sound quality no matter where you are.

The Basics of Satellite Radio Systems
Satellite radio systems are the consumer's access to space-based audio technology, offering uncensored, commercial-free programming that comes in crystal clear no matter where you are. But how do they actually work?
The most basic explanation is as follows: programming is transmitted to a communications space satellite, which beams a digital signal back to earth. The signal is encrypted, so it can only be picked up by special proprietary equipment. The signal can be broadcast across more than 22,000 miles and received by the end user with absolutely no degradation in clarity or sound quality.
But the basics are only a small part of what makes satellite radio systems work. Many innovations and the use of cutting-edge communications technology have brought digital radio a long way from where it began just over a decade ago.
Digital radio was actually operating in the early 1990s, with Washington-based Worldspace Corp. providing fixed-location satellite radio to Europe, Asia, and parts of Africa. However the technology didn't take off in the US until 1992, when the Federal Communications Commission established the Digital Audio Radio Service (DARS) which allocated certain segments of radio frequency for satellite broadcast.
Two companies bid for and won licences to broadcast in the allotted frequencies: American Mobile Radio, which later become XM Radio, paid $93 million for licensing, and Sirius Satellite Radio forerunner CD Radio paid $89 million. XM made its nationwide debut in 2001, and Sirius followed in 2002.
Though both companies offer more than 100 channels of commercial-free programming that's available anywhere in the US, they took different technological routes to achieve universal coverage.
XM's system relies on two powerful geostationary satellites positioned directly above the equator, which are programmed to move in synchronization with the movement of the earth. To overcome interference from physical obstacles such buildings and mountains, the XM service service relies on a network of repeaters, which are antennas that receive the radio signal from the satellites and retransmit it to the subscriber's receiver.
The Sirius system is based on a trio of satellites that travel in figure-8 shaped orbits. Because these orbiting satellites can rise much higher than geostationary satellites, interference from physical objects is minimized and a large network of repeaters is unnecessary. To keep the signal steady during the eight hours daily that the Sirius satellites' orbit takes them to the other side of the earth, the company leases capacity on a geostationary satellite which feeds the signal to subscribers.
Satellite radio service also depends on digital compression technology, a technique that uses sophisticated algorithms to compress as much material as possible on the available bandwidth.

The Health of Ham Radio Today
The Amateur Radio Service has an almost unduplicated position for a recreational activity/leisure time pursuit because of its historically tight coupling to the wireless telecommunications, broadcasting, and military communications industries. Few other hobbies have supplied such a sizable number of both motivated and trained workers and of useful technological improvements to their associated commercial industries.
There was once a time in the industry when it would have been routinely assumed that an applicant for a technical job was a licensed Amateur and had a station on-air. No longer is that true, of course. But, whether or not most people in the industry explicitly recognize it, the health and survival of the Amateur service is still very important for the industry - if for no other reason, because Amateur radio is one of the few remaining services where an individual can still develop practical, hands-on, trial-and-error RF experience on his own! And since such practical RF experience is becoming scarce in today's raging digital flood, that's not a small concern.
In the Curmudgeon's view the health of the Amateur Service today is only average. Not robust but just "so-so," a kind of flabby middle-age. And that is ironic, for the level of RF technology available to the Service has improved tremendously in the fifty years since the Curmudgeon earned his first license. But during these decades the sociology associated with the Service has degraded considerably. That degradation extends to licensees' on-air behavior, to their motivation and interest to learn and to experiment, and to their willingness just to "lend a hand" to benefit others, whether in helping new initiates to qualify for licenses or in public service activities.
Today's Amateur Service is not your grandfather's hamming. "Yep, Bubb, it really was more fun back then!" Too many of today's active hams are too disinclined to pick up a soldering iron, too egocentric in their on-air operating practices, too focused on artificially-produced competitiveness when cooperation would work equally as well. The character of the Service has degraded over the decades, perhaps tracking that of the larger American culture, and the obvious question is "Why?"
The Curmudgeon ascribes the sociology problem to two causes, one natural and one man-made. The natural cause is the aging-out of the senior ham population and with that the demise of some semblance of historical understanding, experience, and quality in the ranks. That of course is unstoppable. The man-made cause is something that the Curmudgeon now has to admit that he erred in initially favoring. That was the restructuring of the FCC license exam process as manifested by the establishment a few years ago of the "No Code" Amateur Radio licenses (i.e., no requirement to demonstrate ability to send/receive the International Morse Code, plus other unrelated changes).
Prior to the advent of restructuring, earning an Amateur license probably required more than the amount of work and dedication that would have been proportional to the reward, and thus the arduous licensing requirements overly restricted the entrance of new participants. Now the qualifications for the restructured Amateur licenses are probably set too low, and this has resulted in the influx of telecommunications consumers and casual hobbyists in quantities that threaten to seriously change the nature of the Service.
To be fair, the elimination of the code proficiency requirement itself was inevitable; it was a change that occurred in the same time period when Morse Code was also being dropped as an authorized emissions mode for other (commercial) radio services. By itself "No Code" is probably not sufficient to account for all the degradation. Rather, the Curmudgeon believes that the open publication of the license exam question pool, with its "just cram for the exam" ethic, and the concurrent rise of commercial "Amateur exam quick study courses" of various kinds has created much of the damage.
Just consider the advertisements for the nascent "FCC Amateur exam preparation industry." In one case an entrepreneur advertises that an individual can go from zero telecommunications knowledge to passing the (entry level) Technician Class exam in a one-weekend "camp!" In another case an individual possessing the entrance grade license reported that he successfully passed the (highest level) Extra Class exam after just twelve hours of study using an on-line (for profit) Web site. There are testimonials also from individuals who claimed to have passed all three current levels of license exams from scratch in the course of only two months, using the various exam preparation services! These rapid time scales and minimal work loads were unknown in the Service prior to restructuring.
But perhaps the most telling example of the lowered level of the current exams involves an English ham...a chap who is a graduate engineer and a long-time holder of the highest level UK ham license. Recently he attended a UK national ham convention where he unexpectedly discovered that the US Amateur license exams were being given. With no preparatory studying whatsoever, never having ever read the FCC's Part 97 Rules, and acting strictly on impulse, he instantly decided to take the US exams. Ninety minutes later he departed with a new US Amateur Extra Class license! A "special case," of course, but what does it say about the quality of the current exams?
The Curmudgeon asks, "Where is the growth of skills and knowledge that comes with invested time, experience, and dedication to the Service, producing as a natural consequence the ever-increasing ability to pass the exams? Where are the proven benefits from this new license structure to the Amateur Service? To the industry? Isn't this just more instant gratification for the 'I want it....and NOW!' crowd?" And so the culture and quality of the Service shift and continue to move over time.
Overall, this is a serious problem, and there aren't any quick and easy solutions. Much of any reform that may occur will have to come from within the Amateur Service itself. But there is a definite role for the industry in the pursuit of this reform: recognizing, encouraging, supporting, and demanding the improvement of the Amateur Service! Not solely as a pro bono initiative; it's really in the self-interest of the industry too!
