Radios that communicate 2-ways are often referred to as walkie talkies. Many people own such 2 way radios and know the convenience they can provide when you need to communicate with someone who is no right near you.
All radios in your group will need to be set to the same channel before you can communicate. For example, if your radio is set to channel 7 it will send your voice over that channel when you talk, and it will listen for and allow you to hear other people talking on channel 7. It is always important to remember that these channels are public! Always be careful what you say over a two way radio, because you can never be sure who is listening.
The following day, the radio earpiece took my father off the critical list and moved him to a regular room. I was still in shock with the news that Robert was dead.
Going to rob a bank? There's an app for that. The "police chat" app lets bank robbers listen in on security stuff transmissions on their iPhone, and it even flags conversations where key words like "bank robbery" are mentioned.
10-4 actually means a two-person squad car is headed for the scene. A 10-99 means only a single officer car will be arriving on the scene, whereas a 10-1 is an emergency and numerous squad cares are enroute.
Any standard restaurant will have sufficient coverage with a 1-Watt UHF radio. Any wattage beyond that is not useful, unless you plan to go off site as well. In this case, you may want to look into a 2 or 4 watt walkie talkie.
Indeed, seriousness and the need for citizen participation was the tone of Scanner Day. Not too far to the north at the Gary Comer Youth Center, numerous residents watched the South Shore Drill Team perform in the parking lot of their new headquarters, heard community speakers and various performers urging greater neighborhood participation in keeping the streets safe. This was the official National Night Out event sponsored by the Chicago Police Department's Third District.
It is no doubt that two-way radios have come along way over the years. Most people have found them impossible to live without, just like cell phones! From starting out at a maximum range of about 2-5 miles, you can now find them with maximum ranges of up to 14 miles! Next time you are on the go with friends or family, make sure you're prepared and take a two-way radio along. They may just prove to be pretty handy.
The old adage that 'mobile phone emissions can cause cancer' is a commonly held belief that doesn't actually have a huge amount of evidence behind it. Nevertheless, a lot of people genuinely believe that they can/will develop cancer after extensive use of a mobile phone.
Amazingly, this does little or nothing to deter these very same people from using their phones all the time!
To go to the root causes of this belief, we must first talk about the pioneering work of American ophthalmologist (that's an eye specialist) Dr. Milton Zaret. Milton was a giant in his field (and was even unintentionally name checked in a 2013 issue of 'Batman' - no joke). Among Dr. Zaret's most notable accomplishments was his research into the damaging effects that microwave emissions have on the Human eye.
There is a obvious, present and growing danger to the whole population of the UK from contact to the whole non-ionizing segment of the electromagnetic spectrum. The danger can't be overstated because most non-ionizing emission injuries happen clandestinely, usually do not become obvious until after many dormant years, and when they do, the effects are rarely documented.
It seems that there was a lot of political pressure on other researchers to discredit Dr. Zaret and his findings, which resulted in some fairly bad science, but equally in the general notion that Zaret was mistaken. However, his work was never conclusively proved, nor reliably debunked, leaving the case open to interpretation.
Although the emissions that bothered Dr. Zaret (anything from microwave ovens to radar technology) are not exactly the same as mobile phone emissions, the fundamental argument is similar. To date, nobody has been able to prove, or disprove, that mobile phones can cause cancer.
Since the development of mobile phone equipment, studies have been conducted to see if they cause health risks. The fear is rational, given that mobile phones are low-powered microwave emitters, and some microwaves have been revealed to cause health risks. Consumers and Experts agonize that keeping a microwave emitting gadget near your head and/or brain could put you in danger for brain cancer or other harm. The fear is now and again greater in regard to Bluetooth earpieces, as the gadget is located inside your ear and thus even nearer to your brain.
So, the old argument has now been transferred to Bluetooth Headsets (you are by no means the first person to ask this question). The key point being that the earpiece itself is actually much closer to your brain than a mobile phone. However, naysayers simply consider the level of microwave emission produced by the earpiece to be so low as to render the effects negligible.
Essentially, because the widespread use of mobile phones is a relatively recent phenomenon (although it must be said that the first mobile call was actually placed 41 years ago by Marty Cooper), it is simply too early to tell, one way or the other.
Because Bluetooth earpieces are such a new facet, it is not possible to get statistics about continuing effects of constant contact. Some propose that inside 20 years, advanced studies will be presented, as the first generation to grow up using mobile phones and earpieces will in fact be guinea pigs for lasting effects. If you are really worried about the microwave emission from your mobile phone, don't use Bluetooth earpieces and simply use the speaker-phone alternative that is standard on most Mobile phones. even though exact study has not provided comprehensible solutions as to whether Bluetooth earpieces can result in cancer, this may be an area where you feel it is better to be safe than sorry.
In conclusion, it does seem unlikely thatyour mobile phone can give you cancer. It seems logical enough to assume that we'd all be feeling the effects by now, after nearly two decades of mobile phone use (the second of which actually involved the majority of the population). However, nobody really knows for sure... Dr. Zaret may yet be proven right as the prophet of doom (but, of course, we have to hope not).
Recently we celebrated the 40th celebration for the world‚§™s initial mobile phone communication. Inevitable, it was a Motorola employee who completed the historic phone call and, more unsurprisingly, the call was made on the Motorola phone (or, in this instance, prototype telephone). If you are taking one thing from this introductory piece, it ought to be this: Motorola are chief, and when it comes to communications.
With that in mind, I reviewed the GP340 Portable Radio, the standard in a long line of excellent Motorola radio devices. The following is what I thought about it.
With up to eleven hours of battery, signal encryption and a selection of VHF or UHF bands, the GP340 hits the ground successively and goes from there. A well-built, slightly military-esque device gives the GP340 a professional appearance and facilitates for significant sturdiness across numerous environments.
At 137mm high, 57mm wide and weighing just 420 grams, the GP340 is also naturally moveable, which adds to the complete feel of this two way radio as an ‚§˜action‚§™ radio, possibly better matched than most 2 way radios to more involved use.
What is further, you get sixteen audio channels, as well as a ‚§˜channel scan‚§™ function.
There‚§™s no screen to be found here, which is possibly a shame, but I disbelief this will influence the device in any major way, to be frank.
Someplace between ¬£230 and ¬£280, depending on where you search. It pays to run a thorough web search at this point, because there looks to be quite a few offers going on at the moment.
The GP340 is certainly more of a team walkie talkie, especially if that company happens to be posted a considerable distance away. To quote directly from the Motorola website,
‚§ĹStreamlining operations with two way radio communication increases productivity and can outline part of an businesses health and safety structure that is particularly significant for individuals who work on their own or isolated from the squad‚§.
This is incredibly true, as the inclusion of a dazzling orange ‚§˜emergency button‚§™ as well as an ATEX-approved ‚§˜mandown‚§™ option board capably demonstrates Motorola‚§™s commitment to user security. If you're a organisation owner and shopping to outfit a group (particularly one going into a probably dangerous situation) with 2 way radio units, you could do a lot worse than a set of Gp 340s.
In addition, the audible ‚§˜low battery‚§™ alerts are helpful and typically unobtrusive. On the other hand, if you use the changeable power level use, you can make the battery life survive that little longer and save yourself the sound.
The ‚§˜Call Forward‚§™ function is also an conclusive treat, allowing you to, in essence ‚§˜leave a message‚§™ for a user who is otherwise indisposed.
This looks like one more great 2 way radio from Motorola. The numerous, well-designed and considerate security features on this one are a real plus point, as is the universal durability and craftsmanship inherent to almost all Motorola 2 way radios.
The whole impression of this 2 way radio is one of carefulness and consideration. Workers can feel that their employer genuinely needs to keep them secure at all times and employers can recognize that their labor force are continuously contactable, especially in an crisis.
It lacks the crystal clarity and audio-level adjustment of the DP3400, but that‚§™s about the only weakness I can discover with it. Even then, the signal is normally clear and passable. This premium level of presentation, along with a pail load of features to aid everything from user safety to battery life, is what makes the Motorola gp340 a real winner.
One of the questions that we are asked frequently is do All Walkie Talkies Work Together, if a new two way radio that a customer is considering purchasing will be compatible with older radios that they already have. This compatibility question is best answered based on the type of radio (consumer vs. business), as the answer is very different.
Consumer radios operate on a standard set of frequencies, either the GMRS or FRS services or a combination of both. Most newer consumer radios are "dual service" radios that support both FRS and GMRS. These radios will typically have 22 channels. Older consumer radios may only have 14 channels, operating only on FRS.
Regardless, all of these radios that support FRS and/or GMRS use the same frequencies and are compatible with one another. Simply set all radios to the same channel number and privacy code, and you will be able to communicate. Popular manufacturers of consumer radios are Audiovox, Cobra, Garmin, Midland, Motorola (Talkabout series), and Uniden. Kenwood used to make GMRS models (the TK3101 and TK3131, for example), but have moved away from consumer radios and no longer produce them.
Compatibility is not nearly as straightforward when it comes to business radios. First of all, there are several types of frequencies that business radios are made to support: VHF, UHF, and 800/900 Mhz frequencies, for example. The first step in finding a compatible radio is choosing a model that supports the same frequency type as your existing radios.
These frequency types refer to an entire range of actual frequencies, and just choosing the same frequency type does not guarantee compatibility. If you purchased your existing radios from a true two way radio dealer, there is a possibility that the dealer could have programmed special custom frequencies into the radio. If this were the case, your radios may not be compatible with a new radio even if you purchased the exact same model.
Usually most compatibility issues arise with 4 or 5 watt radios, which are much more likely to support custom programming. With one or two watt business radios, it is a little easier to ensure compatibility. The Motorola CLS series of radios and the two watt RDX series models will always be compatible, and two watt Kenwood radios that are marked with a ProTalk label will always be compatible, provided you purchase the same model.
If you have any questions or concerns about business radio compatibility, the easiest option is to simply contact us and we can recommend a compatible solution. For older radios or radios that could have been custom programmed, we may ask that you send in the radio so that we can read the actual frequencies from the radio before making a recommendation.
