Two Plan Radios And After This And Before



General Mobile Radio Service (GMRS), Family Radio Service (FRS) and the new 900 MHz walkie-talkies are all designed and built for the same purpose: short to medium range communications for personal or business use. However, there are notable differences between the three!

Truly, their demands are becoming high-tech." A few youngsters who had won a ticket to the North pole arrived tired and almost out of breath. They were assigned the special task of inviting Santa to the icom two way radio earpiece of Child rights. Santa would be the key speaker and in his address to the children representatives from around the world, he was to highlight on issues of global warming. It was in the news very recently that Santa had slipped into a pool of ice cold water because of the friction between his sledge railings and the hard ice surface. The Hospital at North pole had announced Santa to have lost a ligament and advised him complete bed rest.

Tie one icom radio end of the line to the crown or lower part of the anchor. On lightweight anchors like the Danforth or Fortress, locate the crown where the shank (the long arm) and flukes meet. Stockless anchors--like the Bruce, Delta, or Rocna--often have a small hole drilled where the shank bends down toward the flukes. On a CQR anchor, attach the line to the rear horizontal bar.

Today's bass fisherman is far better equipped: Top of the line rod, reel and a dozen or so assorted lures of all sizes shapes and colors. His bass boat has a GPS, a depth finder and a marine radio so he can keep up with what is going on around the lake.

Find one or two that you find entertaining and put them onto your mp3 player or listen to them at the computer. Gradually you will start to understand the subject well enough that you can hold a conversation on it. You may not remember everything but you will gain enough information through listening to figure out whether you want to pursue the hobby Icom radios further or not.

Portable Airwaves Buyer's Guide

All of the major cruise lines, including Royal Caribbean, Princess, Carnival, NCL and Holland America spend millions and millions on marketing to convince you that their particular offerings are different from the competition. In reality, the cruise experience itself doesn't differ much from cruise line to cruise line.



In order for you to be rescued, it's important rescuers find you first. It'll be very difficult for them to locate you if you don't have anything that you can use to point your location to them. Purchase a LED flashlight. This type of flashlight will produce great and bright light and is a battery life saver. You can also purchase flashlights that include a strobe mode. This is an effective signaling device for night rescues.

Add a soundtrack to your workouts - invest in a DP 3400, CD or MP3 player. Adding music to your workouts can add interest and motivation while your train. Up-tempo music works best, but any kind of music that inspires you is great workout music.

This super breed of chimpanzees does not make their nest in the tops of trees like the smaller ones. Instead they make their nest on the floor of the jungle. You might ask how such chimps can survive sleeping on the ground when there are huge cats, lions and other dangerous animals around. It appears that this species of chimps are aggressive predators and other predators know it and simply leave them alone.

A jump-start is a 12 volt lead acid battery which is somewhat like the battery used in cars. They are smaller than car batteries and weigh around 25-30 pounds. This makes them easy to carry around in the car. They can also be used as a backup generator during natural disasters or while camping. They also come with Motorola DP3401 and ultra bright lights.

Many restaurants with outdoor cafes allow dogs at the outdoor seating area. If you're Non-display Portable Radios not certain call in advance. You can also order food from food carts if you're in an urban area.

The main advantages of FM transmitters are that they do not create distortions. They are designed in a motorola two way radio that their frequency modulated wave is less vulnerable to interferences from buildings, noise. Thus, they will provide better signals. FM transmitters with higher wave frequency can receive more data as well. They use less radiated power also.

Try to cover any open spaces underneath the house, leaving only one entry on the raccoon's den. Try to use a non-display portable radios near their shelter and tune it onto a talk station. Turn the radio on during nigh time just enough for the animals to hear it. This will give an impression to the raccoons that there are humans nearby the shelter and in due time they will leave and look for another place. If in case this method is not effective, then try focusing bright light on the den to ward them off. Another solution is by placing rags soaked in ammonia around the den. The smell of ammonia will irritate the raccoons and forcing them to leave.

When his work is done and The Rock and his radio drive down the road, I'll miss the journey his music has provided. So in the end, I guess it's not all about youth and muscles or The Rock's plentiful hair. And it's not about painting either. It's about comfortable memories and the ability to dream in your fuzzy slippers.

Radio 101: Operating Two-Way Radios Every Day and in Emergencies

Two-way radio communication may seem like a thing of the past with smart phones and the availability of more advanced technology. However, with the recent frequency of natural disasters, storms, and other emergency situations, more attention is being paid to radios as a reliable form of communication and a possible back-up communication option, including amateur radio operators.

For example, the Times of India reports that the recent monsoon flooding disaster in the northern India state of Uttarakhand in July 2013 has prompted officials in other flood-prone regions to establish Amateur Radio facilities to provide emergency communication.

What are two-way radios andhow do they work?

According to Wikipedia,

A two-way radio is a radio that can both transmit and receive (a transceiver), unlike a broadcast receiver which only receives content. A two-way radio (transceiver) allows the operator to have a conversation with other similar radios operating on the same radio frequency (channel).

Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called walkie-talkies or handie-talkies.

Radio 101

9780160910012A recent training publication produced by the Department of Health and Human Services, Centers for Disease Control and Prevention and the National Institute for Occupational Safety and Health called Radio 101: Operating Two-Way Radios Every Day and in Emergencies provides training materials on how to operate two-way radios. Included are an instructor’s guide, a DVD with a power point presentation and a student handbook. These training materials practice what they preach, in that they are brief, straightforward and concise– just as two-way radio conversations need to be.

While many of the scenarios used throughout the training materials apply to miners and situations where miners would need to use two-way radios, the information is generic enough that it is applicable to any emergency.

Two-way Tips

The information provided in the training materials seems like common sense, but there are a few important tips to consider when using two-way radio communication in an emergency situation:

Less is more. Be brief and efficient; know what you are going to say before using the radio so you do not tie up the channel while you are thinking of what to say.

Don’t mind your manners. It is not necessary to be polite, saying “please” and “thank you.”

Repetition rocks. Repeat back information you receive to confirm that you heard the correct information.

No privacy policy. Be aware that conversations are not private on these open channels and may be heard by others picking up your frequency. However, this downside is a big plus in emergency broadcasts and SOS situations where the operator wants as many people possible to be listening in to be able to pick up and relay his message.

License to Help

To operate an amateur two-way radio in the United States requires taking a test and obtaining a license from the FCC (Federal Communications Commission). The American Radio Relay League (ARRL) is the national association for amateur radio (also called ham radio with operators being called “hams”) in the US and “provides hams and non-hams the resources to learn, get licensed, and help others on the air.”

Amateur-Radio-Emergency-ServiceAlready have your amateur radio license and want to help your community? Check out the ARRL’s Public Service page for training, resources, manuals and more. The Amateur Radio Emergency Service (ARES) consists of licensed amateurs who have voluntarily registered their qualifications and equipment for communications duty in the public service when disaster strikes.

Recently, the American Radio Relay League hosted their national Field Day where amateur radio clubs across the country gathered locally to test their radio equipment and practice communication strategies in the event of an emergency. Learn more about Field Day.

Rules of the Radio



Together with the Radio 101 training guide, two-way radio operators who want to learn the “rules of the radio” often buy the latest United States Frequency Allocations: The Radio Spectrum Chart (shown below). This poster shows through color codes the parts of the radio spectrum that are allocated to each type of radio service, including amateur (ham) radio, commercial radio and television broadcasting, radio navigation, mobile, satellite, and others.

9780160908958Finally, the definitive sources of radio regulations, frequencies and procedures can be found in the Manual of Regulations and Procedures for Federal Radio Frequency Management and the Code of Federal Regulations Title 47 (FCC Rules and Regulations).

It is important to be prepared in any situation and not rely on only one form of communication. Thus, it is comforting to know that amateur radio operators are working on behalf of their communities to help during emergency situations.

What is Ham Radio & How Does it Work?

Ham radio (so called because its operators were originally derided as being ‘hammy’ in the 19th century, when the technology first emerged) is a term that applies to any form of amateur radio broadcasting.



There are designated radio frequency spectra available solely for public use. Uses range from recreation to communication and the non-commercial exchange of ideas. ‘Hams’ take advantage of these frequencies in order to transmit any number of things

Strictly speaking, there should not be any money involved in amateur radio (hence the term ‘amateur’). Although the majority ofHam radio practitioners are actually extremely knowledgeable about radio technology (don’t let the ‘ham’ part fool you), they are not considered professionals because they do not profit from their endeavours. Conversely, commercial broadcasting involves (a lot of) money: royalties are paid, producers and performers are paid and the whole thing is ultimately a commercial exercise.

Hams use a large amount of frequency bands from all across the radio spectrum, but the majority of frequencies are to be found just above the AM band.

A lot of hams, however, use VHF FM, operating hand-held transceivers that send on one frequency and receive on another. Local radio clubs set up FM Repeaters (which borrow space from other broadcast devices such as towers and, in doing so, amplify the radio signal’s strength hundreds of times over), so that hams can communicate with each other wirelessly over a distance of hundreds of miles.

As an example of what hams get up to, here’s an excerpt from Gary Brown, of How Stuff Works.com

“Although a ham radio does broadcast in all directions, hams generally do not use their radios in a broadcast kind of way as a disk jockey would at a radio station. In normal AM or FM radio, one disk jockey transmits and thousands of people listen. Hams, on the other hand, conduct two-way conversations, often with another ham or with a group of hams in an informal roundtable. The roundtable of hams may be in the same town, county, state, country or continent or may consist of a mix of countries, depending on the frequency and the time of the day. Hams also participate in networks, often called nets, at predetermined times and frequencies to exchange third-party messages. In the case of disasters, hams exchange health and welfare information with other hams”.

To become a ham, I recommend that you join a club. You’ll need an amateur radio license, of course, but this won’t break the bank, I’m sure.

I hope that helps, Melissa.

What Does Two Way Radio Mean?

A two way radio is one that can transmit and receive. It is also called a transceiver. The two way radio definition encompasses most of the wireless or cellular systems. Portable devices which use the two way radio system are called walkie talkies or handie-talkies. The transmitter on a two way radio device is turned on by pressing a push-to-talk button. Pushing this button sets you free to start talking through the device. There is normally another person on the other end of the conversation, or a group of people who have devices which use the two way radio system.

The 2 way radio technology is one of the earliest wireless network technologies. Despite the fact that there are countless other ways of wireless communication due to innovation, the two way radio system is still viable and used by people to widen their communication range.

It is mainly used due to the following two main advantaged:

Communication is Instant

The two way radio system enables instant communication. Within a fraction of a second after pushing the push-to-talk button, you would be able to pass on your messages . This has been made possible by a quick call set-up time integrated in this technology. The reliance of organizations on the two way radio system is founded on the fact that the device enables instant communication.

Group Communication is Possible With This Technology

This is a distinct feature of the two way radio technology. The capability of this system to create a scenario where a whole group communicates even from distances apart is also called “group call”. It is very efficient in that one caller is able to convey a message to up to thousands of other users at the same time. Not one user receives his/ her message later than the others in a group call. The conveyor of the message does not need to repeat himself/ herself so that the message is heard by everyone in the group communicating. Very little radio frequency channel resources are used during the group communication, meaning that it is not a way that utilizes so much of an organization’s resources.

Benefits of a Two Way Radio System of Communication

All wireless technology systems of communication have their advantages and disadvantages. Organizations or groups have their preferences in regards to how they conduct their day-to-day businesses.

A two way radio system of communication is superior to other systems of wireless communication due to the following key reasons:

• It is suitable for people who are mobile hence are rarely together to carry out their duties and responsibilities close to each other.

• It is suitable for communicating among a group of people.

• Communication using the two way radio system is instant.

The aspect of a two way radio system of instant communication enables emergencies to be handled pretty fast. A situation that requires urgent attention can be attended to as fast as possible. A cellular phone would be a great option for communication of emergencies, just that, they take time as the person on the other end of the call has got to receive first so that the message is conveyed. The few seconds or possibly even a minute as the phone rings could create an avenue for the situation to worsen. A two way radio system only requires you to push a button and then convey the message straight-up, as long as the radio frequency channels are available. In the event of congestion on the radio frequency channels, the two way radio system is designed to overcome this and create a priority in the event of an emergency. This feature is not available to other technologies of the wireless system.

Conclusion

What Does Two Way Radio Mean, The two way radio system is very efficient and economical. Making phonecalls to more than 5 members of a particular group would be pretty expensive as compared to conveying messages through a two way radio system. It would also take time to call one member after the other, a situation that would not arise with the two way radio technology.

The Extended Street Home: Radios employed in Transport systems as well as Fleets

According to the UK Government, there were an estimated 5.2 billion bus passenger journeys undertaken on our roads in 2011/2012. Public and private transportation is not only big business; it is also of massive importance to the smooth running of the country.

Whilst only 14% of the UK’s 25 million commuters travel to work by bus or train, this still accounts for over 1.7 million people. In order for a country this reliant on public transport to survive and thrive, it is absolutely imperative that transport workers can communicate with each other in a quick, efficient manner, fuelling an industry that, by necessity, spans the length and breadth of the nation.

Two-way radios provide the solutions to this monumental challenge.

Rail, bus, here make use of two-way radios in order to keep up to speed with vital information. Drivers and managers can easily contact command and control centres, as well as liaising with depot staff and even customers, all due to using their radios. Together with integrated GPS systems, radios help transport and fleet workers to track deliveries in real time, as well as informing would-be passengers or commuters of any delays or early arrivals.

But it isn’t just truckers making deliveries, commuters travelling to and from work and trains running on time. Public transport is one of the most important aspects of the tourism industry, itself a large part of Britain’s economy. Visitors flock from almost every country on Earth in order to visit popular sites like Stonehenge, The The Tower of London, Buckingham Palace and the beautiful city of Bath. Without a reliable public transport system, our tourism industry would be seriously harmed.



So, in order to keep things running as smoothly as possible, all relevant personnel are equipped with a two-way radio so that they can keep in direct contact with their colleagues, peers and managers. This also allows for speedy customer service, as well as up-to-date and reliable information.

Health and safety is also a huge concern regarding public transport and, since the tragedy of the London bombings 8 years ago, security is also a large issue. Workers specializing in either area find their radios to be among the most vital of their tools.

Transport companies employ a veritable army of security staff, as well as first-aiders all of whom are connected via rugged and reliable two-way radios.



Without radios, the country’s public transport system could very well come to a standstill. The roads and railways of Britain are, at least in some ways, kept in operation via a network of two-way radios.
