How Ham Radio Can Benefit Kids As Both A Hobby And Educational Outlook

The world is full of really cool, well written content pieces. If you find one which catches your eye, you have got to repost it, well i do! so with authorization of the original blogger i have posted this for you to take pleasure in

Thus, since the dawn of time, mankind has used alternative means of communication whenever possible. Of course, as the technology has progressed, communication has taken on different forms. Perhaps, one of the most popular forms of communication is by using ham radios.

Ham Radios require a license, which forces the student to undergo radio theory and principals, while at the same time making the hobby fun. This often wets the students’ taste to such a degree, that they are often motivated to work towards a high paying technical career, such as an Electrical Engineer or RF Broadcast Engineer.

Ham radios are special that in order to perform well in the hobby, you need to fully understand the electrical and radio frequency concepts involved. Ham Radios are designed to be used over long distances by using wireless communication. The essence of ham radios are radio frequency transmitters that were used to send radio signals over long distances. Hence, ham radios are analogous to short wave radios which allow you to communicate over long distances. In essence most short wave ham radios start working just above the AM range and they go up all the way to citizens band. In essence, ham radios start to operate just above 1.6 Megahertz and they end up working all the way up to the 27 MHz range. Of course, in the morning, higher Megahertz ranges may be preferable, while at night the lower frequency ranges are more popular.

In principle, the radio waves of ham radios have short wavelengths, but high frequencies which cause them to be packed with energy. They bounce of the ionosphere instead of being absorbed and as a result, this causes them to be able to travel to long distances. In fact, you may be surprised at how easy it can become to communicate, as you would be able to talk over long distances. It is not that surprising to talk over long distances with ham radios such as around the country, overseas and even across oceans. In some cases, you can also use ham radios to communicate with astronauts in the space station.

The use of the Ham Radio Equipment itself requires an understanding of concepts radio frequency technology as well. Ham Radios are as ever complex as govt and often at times as technical as maintaining a braodcast station. The Icom IC-706MKIIG for example has hundreds of controls for both the transmit, receive, and audio characteristics of the signal. The Icom IC-706MKIIG is one of many such complex gear used by Amaeteur Radio Operators.

Hence, you can use the ham radios for all kinds of amateur communication needs both for educational and entertainment purposes. You can use ham radios to further your education by speaking with people from different places. You can easily speak with other persons who speak foreign languages. Let’s say that you are learning Spanish or French. Then you can easily find other amateur ham operators overseas who will be able to speak French or Spanish with you. Thus, it is possible for you to advance your foreign language skills. Moreover, if you are interested in a certain profession, you can easily find people of that profession and talk to them over a ham radio. You will be surprised at how open ham radio operators can be with each other as you will be able to get the help and the assistance that you need.

Moreover, speaking with other ham operators can be fun, as you would be able to meet multinational people all over your country and all over the globe with a ham radio. Especially for teenagers, there are special days in which teenagers everywhere will listen on their ham radios.

NEW MEADOWLANDS STADIUM KEEPS STAFF TALKING AND FANS HAPPY

headphonesThankyou for reading my blog, here’s a piece of writing i really loved reading. With their authorization i can repost it. I compose plenty of my own articles, but occasionally post other articles i find fascinating, thanks for reading.

New Meadowlands Stadium deploys digital MOTOTRBO™ radios with Capacity Plus to help employees collaborate and ensure superior guest experience.

New Meadowlands Stadium Company needed greater capacity and coverage for its new 2.1 million square foot stadium but obtaining new frequencies would be

a challenge.

With nearly 4,000 workers trying to keep more than 82,000 enthusiastic football fans happy in the new stadium, staff would need to rely heavily on two-way radios to communicate. Having leased an analog system in the old stadium, which would not

provide the sufficient capacity and coverage required in the new stadium, the organization decided to purchase a new system. This meant obtaining new frequencies—­­a challenge, especially in a major metropolitan area.

SOLUTION

MOTOTRBO digital two-way radio system with Capacity Plus would easily accommodate the stadium’s expanded workforce and enable coverage throughout the stadium.

MOTOTRBO digital technology divides each frequency into two time slots, doubling the number of users on

the system and reducing the number of frequencies the organization would need to purchase. MOTOTRBO also provides crisp, clear audio all the way to the edge of the coverage area, extending usable range. And with MOTOTRBO’s noise-cancelling technology and sophisticated audio accessories, even most staff working inside the noisy environment of “the bowl” on game day would be able to clearly hear messages.

RESULT

With New Meadowlands Stadium’s MOTOTRBO digital two-way radio system, staff can easily collaborate and offer excellent service to fans.
“Motorola is a very strong partner to the National Football League (NFL) and the Official Wireless Communications Provider of the NFL for the past

13 years. MOTOTRBO radios gave us the opportunity to control our destiny,” says Peter Brickman, New Meadowlands Stadium CTO. “We wanted our

own frequencies; to own our own hardware and maintain it; and ensure that our people would have the communications they needed to do their jobs. The MOTOTRBO system is a vital asset to stadium operations.”

Opening its doors in March 2010, New Meadowlands Stadium, located in East Rutherford, NJ, is the new home of the NFL’s New York Jets and New York Football Giants. Also serving as the venue for many other large-scale events, the stadium can host 82,500 fans and offers the latest technology for quicker ticket scanning, faster trips to the concession stand and instant HD video highlights throughout the building

to provide memorable event day experiences for all guests.

The first of its kind

As the first venue in the nation to serve as home for two NFL teams, the $1.6 billion, privately financed New Meadowlands Stadium is a 50-50 joint venture between the New York Jets and the New York Football Giants. Completed in early 2010, the stadium employs nearly 4,000 workers and will host 20 NFL games per season, as well as numerous other events ranging from international soccer to high-profile rock concerts.

New stadium, even higher standards

With the introduction of its new venue, the New Meadowlands Stadium Company committed to providing an exciting and safe event day experience for all guests, a goal each employee takes very seriously. In order to achieve that goal, however, staff members must be able to seamlessly communicate and collaborate, no matter where they are within the stadium or on the grounds.

“It was vital that every one of our departments, from Security to Guest Services to Operations, would be able to identify issues and resolve them quickly,” says Peter Brickman, New Meadowlands Stadium CTO.

Addressing capacity issues first

Trying to keep more than 82,000 enthusiastic football fans happy in the new stadium requires staff to depend on two-way radios to communicate. Prior to moving from the old stadium to the new facility, a leased analog system was employed. However, with the much larger stadium and larger staff, that system would be unable to handle the load, resulting in numerous channel busies and unacceptable radio interference.

One potential solution to the problem would be to add frequencies; however, obtaining enough frequencies, especially in a major metropolitan area, can be a problem.

“When we started the process, we were told that it would be extremely challenging getting all the frequencies we needed because they just might not

be available,” Brickman says. “We knew we would need to find a radio system that we could build and manage around the frequencies we would be able to get in order to adequately meet the organization’s needs.”

Next, extending coverage and improving audio quality

The size of the stadium also represented a coverage challenge. The massive 2.1 million square foot arena was too large for the limited range of the analog radios. Inadequate range would prevent the consistently available communications Brickman needed in order

to ensure that stadium staff had the tools they needed to fully collaborate and get the job done quickly and efficiently.

And finally, audio quality was a concern. Anyone who has ever managed an arena that hosts sporting events, concerts and other activities that bring together large numbers of fans is familiar with the importance of a communications system that can overcome high noise levels. Audio quality would be a critical requirement at New Meadowlands Stadium, especially in the midst of extreme noise produced by high-energy game days when touchdowns and great plays can raise crowd noise to levels of 120 decibels (dB) or more.

New Meadowlands Stadium opts for MOTOTRBO Digital Radios

New Meadowlands Stadium Company decided to purchase a new system that it could own, operate and maintain itself. That also meant obtaining new frequencies—­a challenge anywhere, but especially in a major metropolitan area.

Brickman knew he had a challenge on his hands and called in experts from Regional Communications, a local Motorola channel partner, to discuss a solution. Regional Communications recommended a MOTOTRBO digital two-way radio system with Capacity Plus.

Double the capacity, extend range and enjoy crystal clear audio

MOTOTRBO’s digital technology would address New Meadowlands Stadium’s capacity issues by dividing the stadium’s frequencies into two time slots, doubling the number of users on the system with no increased risk of interference, and enabling the use of multiple data applications. Capacity Plus, a single-site trunking solution, would expand system capacity even further, enabling over a thousand radio users to quickly and efficiently share business-critical voice and data communication on the same system while using the same frequencies obtained by New Meadowlands.

“MOTOTRBO’s digital technology would allow us to not only double the capacity of our existing channels, but also cut them into the 30-plus talk groups that we needed. It would use the spectrum we were granted very efficiently and establish a stable communications environment for New Meadowlands Stadium.”

Peter Brickman, New Meadowlands Stadium CTO

The company purchased a MOTOTRBO system that consisted of digital portable radios, an MIP 5000 dispatch console that tied into MOTOTRBO control stations, and six repeaters for 12 voice and data paths. To address the needs of each specific job function, the stadium also purchased a variety of audio accessories that would provide the level of capability required by security, guest services, parking and the management teams. For example, noise-cancelling remote speaker microphones and headsets enable messages to be heard, even by those working in the “bowl” during games and concerts. The security team, that required greater discretion, opted for two-wire surveillance kits. All radios were equipped with text messaging capabilities.

A new communications system fit for a new stadium
New Meadowlands Stadium now has consistent and available communications throughout the facility and parking area. With the ability of Capacity Plus to handle up to 1,200 users per system, there is enough capacity to ensure that every employee who needs to will be able to communicate every time. And because it did not have to purchase additional repeaters to accommodate the added capacity due to split frequencies, costs were kept to a minimum.
Calling all hands or select individuals

The stadium’s MIP 5000 VoIP Radio Console uses a multicast-enabled IP network, simplifying installation and saving time and money. With the addition of a text application, dispatchers can easily send group text messages to all employees, to select groups or to individuals as needed. For operations and security, this

feature lets dispatchers alert appropriate staff members when gates are ready to open, when the game has started, when it’s half time or when the game is over.

The system also allows staff to quickly react and work together during emergency situations. “We’ve had situations where we’ve had to quickly communicate to our fans and staff,” says Brickman. “On those occasions, dispatchers do a radio all-call and then follow that

up with a text message so they can document the communication. If someone misses the all-call, their radio provides a supplemental alert to that user that lets them know something is going on that they need to be aware of.”

“The stadium is like a small city”

Whether staff is trying to respond to guest requests, such as additional refreshments for one of the suites, or fix an escalator that is malfunctioning, the reliability and quality of the MOTOTRBO system improves efficiency, productivity and ultimately guest satisfaction.

“With over 82,000 people and 4,000 employees on site on any given day, the stadium is like a small city,” says Brickman. “You’re trying to keep everybody happy and safe and that means we need to get our people where they are supposed to be, ensure the safety and security of guests and staff, and keep things running smoothly.”

If you use motorola two way radios in your work, then you need to read this

headphonesWithout giving too much about this radio accessory piece of writing, but I thought it remarkable and appropriate to what Im currently doing.

We spend a lot of time writing about Motorola radios, so weve decided to do a series that focuses on the earpieces that connect to them.

Not only do a number of good companies make top-of-the-range two-way radios that are both affordable and reliable, there are also a large array of radio earpieces that range from cheap and cheerful (but nonetheless effective) to the last word in techno badassery (Editors Note: not actually a word).

So, kicking off our new 5-part series celebrating two-way radio earpieces, is the GP300 earpiece.

Earpieceonline.co.uk lists this thing at a paltry 11.50, but the GP300 is surprisingly high spec for such a cheap device.

Firstly, the GP300 is totally versatile, as it fits into any 2-pin Motorola radio. It may not be the best earpiece ever manufactured, but it will fit with any number of quality Motorola radios. However, I should say that the 300 does require an adaptor block to work with GP320 and GP340 series radios (oh well, you cant have everything!)

Secondly, the sound quality is excellent; there will be no misunderstandings or botched communications when the GP300 earpiece is in use, thats for sure. For such a cheap device, it actually reproduces sounds amazingly clearly.

Thirdly, there are the features. These features are a bit thin on the ground when compared with some of the costlier Motorola earpieces, but they still enhance the user experience and add to the overall product.

Want examples? Well, the GP300 is ergonomically designed to fit your ear canal comfortably and is easily able to fit in either the left or the right ear (whichever you happen to favour).

It also has an in-built push to talk button, so youre not dependent on your two-ways controls in order to send an outgoing signal. There is also has a sprung metal clothing clip that attaches the GP300 earpiece to whatever you happen to be wearing, allowing you to be discreet, as well as to avoid tangling yourself up in cable.

Overall, the GP300 is a fine radio earpiece. Various companies have made better ones and I wouldnt suggest this one if President Obama asks your firm to guard him on his next family skiing holiday, but for most intent and purposes, the GP300 earpiece gets the job done.

In our next episode, well be taking a look at the GP340 earpiece.

Will I be Able to Hear Bone Conduction Headphones Even if I Wear Earplugs?

When we found this article we were so pleased, having looked for over a year for this, discovering it on this blog was an thrilling day for yours truly.

Because bone conduction bypasses the ear entirely and directly stimulates the ossicles (which is the scientific name for the tiny bones that reside in your inner ear, as well as the rationale behind comic book hero Daredevil’s athletic prowess), it is entirely possible to stick your ear plugs in and still listen to your ‘Bonephones’.

In some respects, it’s actually preferable. Y’see Nick, using headphones is fine and dandy, until you have to turn the volume all the way up in order to drown out noisy children, busy traffic and/or people shouting into their phones all around you. After that, if you increase the volume to too great a degree, you can expose your ears to sounds that can actually permanently damage your hearing.

Bone conduction, however, carries much less of a risk, because it does not effect the parts of the ear most at risk from loud noises.

Hearing is a process that actually has several stages. At first, your ear picks up sound waves, the sound waves pass into your middle ear (specifically, your auditory canal) before hitting the eardrum. The eardrum then vibrates, passing the sound down to the aforementioned ossicles (‘aforementioned ossicles’ is a lovely phrase, don’t you think?) From there, the ossicles transmit the sound to the cochlea, which is a fluid-filled structure that encodes the sound information in order for our brain to decode it (this is not unlike the way a wireless mouse works, actually).

Yup, the inner ear is a wacky world.

Essentially, bone conduction technology rattles the ossicles in the same way that they’d rattle in your inner ear, it just, to turn a phrase my father is particularly fond of ‘cuts out the middle man’. It really is an interesting invention.

So, as you see, there is no way a pair of earplugs pose any problem at all to your enjoying music or audio content on your Bonephones. I hope this helps. You’ll likely find this method especially useful if you happen to find yourself on a long plane journey and seated next to a disgruntled infant.

I’m actually fairly certain that bone conduction technology was invented during a similar scenario.
