What exactly is the HD radio and how can it be compared to the satellite radio?
You've probably noticed that more and more commercials advertise this new thing that you have not heard before: the HD radio. It is said that "no uncovered content" and digital quality sound are heard. Probably even heard the best part of the whole ad: "No subscription fee!"
Let me help you know a bit about HD radio. I try to keep it simple to give you all the information you need with as few technical languages as possible. First of all, you probably heard about HDTV and if you have not heard of it yet, I guess you are living in a cave. HD radio is not the same as HDTV. HD in HDTV means High Definition. Do not be fooled by the HD radio because HD in this context is hybrid digital.
It also provides much better radio transmission than traditional radio signals. Some HD radio stations broadcast 5.1 Surround Sound digital sound to enjoy the real concert experience. You can be sure that in the future more stations will choose the way forward.
Digital and subchannel
HD radio allows radio stations to transmit digital information over FM and AM frequencies to different radio stations. In addition, these digital broadcasts can be sent on multiple subchannels, Three stations are possible. This doubles the number of stations that you can potentially listen to on the HD radio. What will it look like in the display, do you ask?
Generally, standard AM / FM radios show: FM 104.7
HD radio: FM 104.7 HD-1 or 104.7 HD-2 (all HD-X signals subchannel)
From 2007 signal quality is close to CD quality sound on FM channels, which is a huge leap in the radio industry. However, it is highly unlikely that AM frequencies will experience this improvement, as AM operates in a much smaller band. Think of it as a hose. A small garden hose could not carry as much water as the hose of the fire brigade; and unfortunately the AM is the small garden hose.
In the early stages of HD Radio (2006), reports and complaints were about static and interference when embedded in these HD channels. However, technology has developed significantly in the past two years and has improved the quality and isolation of the signals. Do not worry about loss of quality unless you are in AM channels.
You've also heard that the FCC (Federal Communications Commission) has launched the process of transmitting obsolete analogue radio and television programs. What does this mean to you? Well, you can be sure they're just fixing. Unfortunately, this would mean that most standard AM / FM radio channels would become obsolete in the coming years, which would force you to buy a new HD radio for your vehicle or home.
Satellite Satellite Subscription ($ 10- $ 15 /, and cancellation fees (if you sign up for a "reduced" contract subscription) To receive the satellite radio signal (Sirius or XM), you will need a special antenna and a satellite radio with a built-in satellite receiver or a simple satellite ready standby without the built-in tuner (optional and optional tuner)). Waiting for the distance between 150 and 300 dollars alone on the device depending on what you need (additional tuner or antenna etc.) *
The HD radio is completely free. You just have to spend the money on yourself. Just like Satellite Radio, you can get a built-in HD tuner in the instrument panel receiver or buy it separately (in case you already have a HD Ready headset). They are much more favorable or you can reach anywhere from $ 100 to $ 200 * anywhere.
* Keep in mind that these are general minima and do not take into account other features outside the radio (such as Bluetooth, USB support, 3.5mm Aux input, navigation, etc.). They do not take into account work and parts because every vehicle changes.
Quality and Coverage
Satellite Radio has the advantage of coverage. You can travel to Los Angeles to New York, listen to the exact same station on the entire trip. Satellite radios are usually specialized in stations outside the HD station. For example, there are separate channels for comedy or sport. Satellite radio is also commercially free as you pay for it.
The HD radio locally focuses. You set up local metropolitan stations and would not have the same coverage as the satellite as shown above. Although HD stations are much more like typical non-specialized radio stations, it is possible that they will continue to play a similar program for Satellite Radio in the future.
Both HD and Satellite radio broadcast in digital quality. At this point, one has no significant advantage over the other, because as radio-type transmission and reception, sensitive interference and static. Do not be fooled by the "Satellite" because of this fact.
If you're trying to keep up with the current technology, but you're also saving money, the HD radio update is not that bad. Most well-known brands, such as JVC, Eclipse, and Kenwood, produce a HD Ready radio receivers and are forced to acquire additional accessories. Only a few companies such as Dual and JVC (again) sell built HD radio tuners .
If you break through the listener choice and do not worry about Satellite Radio charges, you should sometimes choose Sirius or XM radios. Many popular brands such as Sony, Alpine and Pioneer sell both SAT Ready and built-in satellite receivers, so you do not have to look for a problem.
Of course, yours is the choice. But one thing is certain. Digital technology is rapidly evolving and is based on the entertainment of sound and video games. Analog (or non-digital) technology is obsolete. Finally, upgrade to digital. Find out what you love and test both. Sometimes the best on the market is not the best for you. Good luck for the digital revolution!
