Can You Recommend The Best 2 Way Radios For A University?

by: luke1975   Keywords: school, communications

Your best bet, be it for general use in academic studies, health and safety concerns or simply security, would be to - employ a digital two-way radio system - , something like the Motorola SL4000. I’m specifically suggesting Motorola because they handle jobs like this all the time, several of which are detailed on their website.

In fact, the Motorola website details a case almost exactly like yours, where this technology was employed to great effect.

According to the site, the Cincinnati State Technical and Community College (CSTCC) was in a situation just like the one you outlined in your email. Here’s the basic issue... - “CSTCC is comprised of three campuses and over 1.3 million square feet.  - - Until recently, the college used an all-analog system, components of which  - - were 15 years old.  According to Raymond Mirizzi, Director of Facilities at - - CSTCC, “We needed to upgrade our whole communications system,” and it  - - was vital that the entire campus be covered with a radio solution that would  - - support very clear, consistent and secure communications”. -

How a two-way radio network helped the situation is also detailed.

There are lots of companies other than Motorola, of course, but there’s no denying that they are giants in their field, with a long history of customer satisfaction. They are something like The ‘A’ Team in that respect. Still, if your budget doesn’t quite allow for bells and whistles, there are a number of quality independent firms that could do a very good job at a slightly more reasonable rate.

The reality here is that bargains are the exception, not the rule. That’s why we’re always so happy when we get one. By far your best bet is to get an expert to design and implement your faculty’s new communications method. It needn’t be the biggest company, but you want to spend a good amount on communications, as they really do save lives.

Walkie Talkie vs Two Way Radio?

by: luke1975   Keywords: Walkie, Talkie, vs, Two, Way, Radio

Although the terms walkie-talkie and two-way radio can be used interchangeably, some minor differences between the two technologies do actually exist. In a professional context, it is best to know which device you are referring to before you refer to it (but this is substantially less important on a day-to-day level).

Essentially, a walkie-talkie is the same as a two-way radio; there is no overt difference between the two. However, because there are so many different radios on the market, a distinction has arisen. The - term walkie-talkie tends to imply - a hobby model, or an otherwise cheap radio. Conversely, the term two-way radio tends to be more readily accepted in a business, as well as any equipment specific, context.

Walkie-talkies were invented around the time of the Second World War and were principally used by the military. Although they came in different forms, the most common version featured a large handset, which had a long antenna protruding from it. Modern walkie-talkies, on the other hand, feature a smaller design, typically with a rugged outer casing and a short aerial. They usually operate via a PTT ( - Push To Talk - ) button and available models vary in range from cheap childrens toys to professional, military grade equipment.

Generally, walkie-talkies are limited to only a few watts of power and a relatively short signal range. To this end, radio services often use a repeater (a device that increases range and boosts signal by squashing unused frequencies) in order to improve the walkie-talkies operation.

For their part, two-way radios, although they are also portable hand-held transceivers (a device that can both - TRANSmit and reCEIVE messages - ) and they also use the PTT system, are slightly different.

A two-way radio is likely to have a stronger range and a harder outer casing. This is because the term two-way radio denotes a better class of product (usually).

Some two-way radios are also capable of sending and receiving messages at the same time; this is called full duplex An example would be a mobile phone, which employs two different radio frequencies at the same time. However, although a mobile phone is technically a two-way radio, the device is very different from what we understand as either a walkie-talkie or a two-way.

The most important distinction is that two-way radio almost always refers to professional, licensed equipment, whereas walkie-talkie more often describes unlicensed, consumer-grade radios.

52-year-old - British author Neil Gaiman - has spoken out against ‘snobbish’ adult judgements being placed upon children’s literature.

The author, who delivered the second annual Reading Agency lecture in central London this week, chose to use this time, at least in part, to speak out against what he feels is a damaging trend in modern literary criticism.

“I don’t think there is such a thing as a bad book for children,” began the author, addressing a crowd that included many leading figures from the arts and entertainment world, as well as several representatives from educational institutions.

“Every now and again it becomes fashionable among some adults to point at a subset of children’s books, a genre, perhaps, or an author, and to declare them bad books, books that children should be stopped from reading,”

“I’ve seen it happen over and over; Enid Blyton was declared a bad author, so was (‘Goosebumps’ author) RL Stine, so were dozens of others. Comics have been decried as fostering illiteracy”.

“It’s tosh, it’s snobbery and it’s foolishness”, he continued.

Mr Gaiman, who’s works include children’s books (Odd The Frost Giants), comic books (Sandman, 1602) and prize winning novels (The Graveyard Book, Coraline, American Gods), has seen his works adapted into popular films (Stardust, Coraline), and has written for several TV shows (Babylon 5, Dr. Who, Neverwhere). He is generally considered to be one of the most prolific and celebrated authors of his generation, so it is likely that his criticisms will carry some weight.

Gaiman continued, saying that, “There are no bad authors for children, that children like and want to read and seek out, because every child is different. They can find the stories they need to, and they bring themselves to stories”.

“A hackneyed, worn-out idea isn’t hackneyed and worn out to them. This is the first time the child has encountered it. Do not discourage children from reading because you feel they are reading the wrong thing. Fiction you do not like is the gateway drug to other books you may prefer. And not everyone has the same taste as you.

He continued with a warning to parents, teachers and even older siblings, when he said that,

“Well-meaning adults can easily destroy a child’s love of reading: stop them reading what they enjoy, or give them worthy-but-dull books that you like, the 21st Century equivalents of Victorian ‘improving’ literature. You’ll wind up with a generation convinced that reading is uncool and worse, unpleasant.”

Gaiman’s own book, ‘Neverwhere’ was recently removed from a High School reading list in New Mexico after a parent complained that it was inappropriate.

Gaiman’s response to this was wry and well-considered, as he told a BBC reporter, “I tend to take books of mine being challenged and occasionally being banned – and very occasionally being burned – as a kind of badge of honour. You know you are doing something right.”

Mr. Gaiman’s concerns were echoed by a number of the lecture’s attendees.

What Does Two Way Radio Mean?

by: luke1975   Keywords: Two, Way, Radio

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.


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.

What Choices Regarding Ham Shower Radios Are Certainly There?

The 1980's brought another first for women in male dominated industries. It brought the first woman in space. Although there were critics who felt she was chosen for the space shuttle journey because she was a woman, Robert Crippen, the Space Shuttle Challenger commander set the story straight; she was chosen because she was the best person for the job.

There are many uses of the shortwave radio band, but the most common communications are: Domestic broadcasting, international broadcasting to foreign audiences, and communication among - IC-4088SR - operators. A popular hobby of shortwave listeners is referred to as DXing. In Dxing the goal is to hear as many stations as possible from as many countries as possible all around the world. Many of these foreign stations provide confirmation in the form of QSL cards, and various other promotional items to shortwave listeners confirming their reception.

D-Star - This networks takes the EchoLink network even one step further. As long as your radio is connected to your computer - this network adds the capability to transmit data files. Here's the neat part. No internet connection or the internet is down? No problem - d-Star can handle the data transfer all via radio! And this network is also FREE!

2) Check the weather conditions. Usually the most up to date weather predictions can be found on government forecasting sites found on the internet. Keep updated and try to stay out of rough weather. Certain icom marine radio frequencies often broadcast boating weather so if the weather looks like it is going to change remember to keep updated. If you must go out when the weather is bad, ensure everyone wears a lifejacket for the entire journey as in an emergency you will often not have enough time to put one on.

Bumpers and ropes are also necessary. Chances are, when using your boat, at some point it will be tied to a dock. Bumpers are useful to protect the outer finish from damage when it rocks against the dock. Ropes, in good condition, helpful to hold your boat to the dock as well as to help direct the boat to the trailer at the end of the day.

There was a time when we had a radio mast that included mounting of a Shortwave Ham antenna, a CB Radio antenna, and our Television antenna together. It was quite the sight in our neighborhood when dad's friends; Jocko and Claude, on a Saturday morning, brought that mast in on a company truck. Dad had built it himself and meant it as a surprise for all of us kids. He had made a decision to involve us in icom communications as a shared hobby. The mast was triangular, built of 1.5 inch thinwalled square stock aluminum, and was 35 ft. in height.

If you don't have an AM/FM radio or a weather/alert radio available a radio scanner (also known as a police scanner or race scanner) can be a good alternative to get information. Depending on the scanner's capabilities, they can pick up a wide range of frequencies, including the NOAA frequencies. Like the AM/FM radios and weather/alert radios, they cannot transmit a signal.

Supply your team with suitable clothing. In some countries the weather can change in an instance. Make sure that they have suitable clothing for heavy rain or extreme heat so that they can use it when required.

The other day I hauled my bod up bright and early perform some playing tennis. I was feeling chipper. The weather was just right. I had my morning coffee. This had all the earmarks on the good life.

In May of great there were some technical difficulties that delayed incredibly launch of the Falcon 9 rocket that owned the particular privately held company spacex. On Sunday evening there were no such problems simply because the rocket soon on its way using the second journey of space vehicle launched from the united states since the conclusion of the Shuttle program last year.

Warning flags have been posted from Cocoa Beach to cape canaveral. It's been more than just a decade since a huge "jellyfish outbreak" like contains almost. Marine biologists believe a bloom of jellyfish in the Gulf of Mexico were transported via Gulf Stream wrapping within coast of Florida.

The X-37B is one-quarter the height and width of the space shuttle. It is about 30 feet long and roughly 10 feet tall, with a 15-foot wingspan. It does have a payload bay much like its larger, manned cousin - but naturally whatever that payload was in this mission - it was classified. Practically plane was constructed using the Boeing Phantom Works. It's operated from your Schriever Air Force Base, Colorado. Another launch of your craft could happen as early as this March.

The solution was as expensive given that turned to get wild. We got to the particular night in Miami, inside only hotel we discover availability at, and fly the overnight to Bahamas to board the cruise on its first conclude.

Most among the restaurants and hotels in Cocoa Beach are along A1A (North Atlantic Road.) When making your motel/hotel reservation, request accommodation with an ocean read. If you would like to camp, try Jetty Park, just north on A1A from Cocoa Beach at 400 Jetty Road, falcon 9 rocket. Telephone: 321-783-7111. Jetty Park includes a beach and has 150 campsites, hosting an assortment of camping styles from small tent to RV.

The fun thing only agreed to be as we left the area, a bald eagle flew above. So, I also any little little pride our country would make it into space.
