Social occasion Overshadowing Information Through Ham Radio

 

A sun based obscuration is coming up in only a couple weeks, and in spite of the fact that with its way of entirety close to the southern tip of South America implies that relatively few individuals will have the option to see it direct, there is an occasion to engage with it even at an outrageous distance. PhD applicant [Kristina] and the association HamSCI are attempting to gain proficiency with somewhat more about the impacts of an overshadowing on radio interchanges, and everything necessary to help is a collector fit for tuning in the 10 MHz range during the hour of the obscuration.

It's notable that specific radio waves can engender further contingent upon the hour of day because of changes in numerous elements, for example, the condition of the ionosphere and the measure of sunlight based movement. What isn't known is explicitly how the ways can change throughout the span of the day. During the obscuration the sun's obstruction is limited, and its effect can be all the more straightforwardly estimated in a more controlled test. By tuning into specific time stations and recording information during the overshadowing, it's conceivable to perceive how precisely the obscuration impacts proliferation of these signs. [Kristina] would like to take the entirety of the information assembled during the occasion to notice the doppler impact that is required to happen.

The undertaking requires a lot of volunteers to tune in to the time stations during the overshadowing (regardless of whether it isn't obvious to them) and there are a couple of more days before this obscuration occurs. On the off chance that you have the necessary equipment, which is basically a collector equipped for getting upper-sideband signals in 10 MHz range, it could be beneficial to try this out. If not, there might be some an ideal opportunity to cobble together a SDR that can tune in (even a RTL-SDR set up for 10 MHz will work) if you can utilize it to record the necessary examples. It's very a period that ham radio could grasp the programmer network.

Survival Radio: 5 Critical Concerns And Why HAM Radio Is The Only Answer

Survival Radio: 5 Critical Concerns And Why HAM Radio Is The Only Answer
By Kurt H Petrich  |  Submitted On July 24, 2014
Want to stay in touch with your loved ones in the middle of a hurricane? Well, if you are thinking about using your trusty cell phone or FRS or GMRS survival radios, then think again.
I want to show you 5 critical issues you need to address. But even if you don't, the truth is, these 5 keys are essential to your survival. So what are they? When it all comes down to it survival radio is about:
1. price 2. reach 3. privacy 4. mobility 5. reliability.
And as I share each of these with you, you'll see why HAM radio is the best solution.
First Concern: Pricing Why is the pricing important when it comes to the best emergency radio? Well, Walmart has some great low priced radios. But watch this. Walmart has two way radios that cost more than a Baofeng UV5R handheld HAM radio. And the Baofeng is of pretty good quality at under $40. The only thing missing is your license. So don't assume that you'll only get bad stuff at low prices.
As for CB radios, emergency handhelds are reasonable priced. You can easily find a Cobra WX or a Midland handheld transceiver in the $70-$100 range. OK, so what's the next essential ingredient to a good survival radio after price?
Second Key Concern: Range Why is reach or range important? Well, do you want to get your signal beyond the neighborhood? If so, then range is critical. For any use beyond your immediate family, walkie talkies are out. FRS or Family Radio Service radios are also out.
GMRS radios say that they can handle 14 miles, but the reality is more like 1 or 2 miles. But here's something interesting.

Some GMRS radios have repeater capabilities. Repeaters are devices spread all around the country that receive and retransmit signals. If you can hit a local repeater, then it can forward your transmissions around the country. The downside to GMRS is that you need a license. So what do you do if you want range but don't want to get a license? Then get a CB.
Now with CB's, their range is better than FRS and you don't need to get a license. With full power, a CB can reach about 4 miles. The limits are your line of sight. If you want to increase your range, then attaching a longer antenna to your CB will do the trick.
Another way to increase range is to get a HAM radio/short wave radio. You'll need a license. At that point, you have access to repeaters which are located all over the country. Some great handheld HAM transceiver examples are the Yaesu VX3R and the BaoFeng UV5R as mentioned earlier.
I think that if you want farthest range, then get your license and pick up a HAM or GMRS radio. But price and range aren't where the search ends. Lets look at another essential survival radio consideration.
Third Key Concern: Privacy Why is privacy important? Well, let me play out a scenario for you that will illustrate the point.
In a disaster, phones go down. So where does everyone run to? The radios. And the more people that are talking, then the less privacy you have. Every radio channel available will have people on it all talking at the same time. It will be utter chaos. For some radios that is.
For instance, with the cheaper radios, the accessible frequencies are very limited. Cheap radio is affordable to many people. Limited frequencies means more people. If you get on an FRS radio in the middle of a disaster, it's going to be very hard to get through to any specific people.
Trying to coordinate with family or friends will be near to impossible. CB will be about the same. So here's where privacy comes in.
Many radios come with "privacy" channels. But there's nothing private about these channels. They are just a cheap feature added to the radio. But with HAM you have a better chance with privacy.
That's because you get a wider frequency spectrum to choose from. For instance you'd have your group start out on a national calling frequency and then move to a special frequency. This special one can be on a ham band or not. It's up to you.
A second factor that thins out the crowds is that HAM operators are required to have a license. And a third factor is that HAM gear isn't as easy to buy as FRS radios. For instance, you wouldn't go to WalMart to buy a handheld amateur radio transceiver. Sure, You can get it through Amazon or eBay, but you're not going to find them at WalMart. So the chances of people buying HAM radios at the last minute is not going to happen.
Fourth Key Concern: Mobility Why is mobility important? Well, what if you have a HAM or CB station setup in your house, and a flood comes? If you have to leave without your gear, then you've got no communications. So mobility is going to be essential.
FRS and GMRS radios are by default mobile. If you want to go CB, then a great mobile CB is the Cobra HH 38 WX ST 40-Channel CB Radio. With the built in antenna, the range isn't that good. Maybe it's a mile.
The downside to mobility is that you can't just plug into the wall for power. Batteries will be at a premium so think about foldable solar panels or a BioLite stove with a USB to power a battery charger. Now although mobility is huge, reliability is even bigger.
Fifth Key Concern: Reliability Why is reliability important? Here's why. You never know what you'll encounter. Let me explain.
Imagine it's raining heavily in a hurricane. Water is everywhere. You are on the run and you drop your radio in the water. Everything is wet and short circuited. End of game.
But, it doesn't have to be. That's because the Yaesu VX7R can withstand 30 minutes of submersion in 3 feet of water. But physical reliability isn't where things end.

Another example of reliability is the use of channels. With everyone crowding existing channels, they increasingly become unreliable to communicate on. But with HAM, you have more to work with. In short, your communications become more reliable.
I Used To Think That FRS Was The Way To Go Maybe you've never considered HAM or shortwave radio. When I first started out, I thought FRS and walkie talkies would do the trick. But after learning more about HAM and all the areas it addresses, I was sold. There were just too many critical areas where HAM blew away FRS and CB.
What I'm going to be doing is start working on getting my license. Then I'll pick up a BaoFeng UV5R or a Yaesu. How about you? Did these 5 critical concerns help you? Do you understand the issues of survival communications a little better?

Survival Radios For Sale - You Will Need One If The Grid Does Down To Save Your Life

 One item that every household should have is a good crank survival radio. If the grid goes down and you don't have a generator with plenty of fuel, you could be in trouble. Your batteries in your flashlights, radios and cell phones will only last so long, then you have no communication. You will pretty much be left in the dark, unless you happen to have some candles and matches.
 Okay so what is your alternative to a dire situation ? Well the answer would be a survival radio that has a crank option to charge up the batteries. Most of the newer survival radios have the capabilities to also charge up your cell phone. They also may have some shortwave capabilities, so you can hear some news from around the world. I have also seen where you can charge up some other batteries. They can be used in flashlights. The survival radio itself also has a flashlight built into it. Another nice feature that they usually have is a solar battery that can be charged by sunlight. It is an excellent idea to have a few of these radios in your house, cb radio shack or ham radio shack.

Every Survival Kit Should Have An Emergency Radio

By Gregory Shepard  |   Submitted On June 23, 2013

Most of the time when you are in an emergency situation you have no link to the outside world. You don't know if it's just your immediate area that's been hit, cell phones don't work and you can't get any directions from civil authorities. You won't know where to go for help unless you have some contact with the outside world. If the power goes out and you need to evacuate, will you even know what to do or where to go without outside communication? It's hard to believe but even today the most reliable form of communication is a radio!
Radios have been the main source of information in times of crisis because the radio waves are consistent and do not require the kind of power that other communication sources do. Emergency radios can provide you with the information you need to make the best choices for yourself and your family. In many cases, a radio may also be your only source of entertainment. During stressful times, music and radio talk shows can provide a outlet for your family that will help relieve stress and keep your mind off of the situation at hand.
You need to have as part of your emergency preparedness kits a hand crank/solar powered radio. These radios generate their own electricity by simply using a crank or the energy from the sun to power them. People have often learned the hard way that sometimes you just don't always have fresh batteries for your radio. When it's your only link to the outside world, these batteries are going to burn out quickly. Having a radio that you do not have to worry about supplying with power can save your life.
Many of these radios can have regular alkaline batteries and electrical AC/DC adapters to augment them as a power source and for charging the built-in (NiMH) rechargeable battery pack. Likewise they will have alternative lighting options built- in such as flashlights. AM/FM radios are fairly standard, but a more complete package will also include shortwave and NOAA capability.
Shortwave radio is a method of enabling world-wide transmission and reception of information. A shortwave radio can receive radio transmission on frequencies between 3 and 30 MHz. It is part of the area on your dial between the AM and FM bands. The main characteristic of these frequencies is their ability to travel long distances as they are reflected back to Earth from the ionosphere. This allows communication around the curve of the Earth making possible world-wide communications. You can hear news and other programs from a wide range of sources, and get emergency information by listening to amateur radio broadcasts from ham operators around the world. Many countries broadcast to the world in English, making it easier to find out what a given country's position is on things that it finds important.
A weather alert radio has features that can be set to automatically receive NWR warnings. NOAA stands for the National Oceanic and Atmospheric Administration, and is part of the U.S. Department of Commerce. NOAA Weather Radio broadcasts National Weather Service warnings, watches and forecasts 24 hours a day. It's an all hazards network that also broadcasts alerts of non-weather emergencies such as national security, natural, environmental, and public safety. NOAA Weather Radio All Hazards transmitters broadcast on one of seven VHF frequencies from 162.400 MHz to 162.550 MHz. These broadcasts cannot be heard on a simple AM/FM radio receiver.

The Kaito KA500 and the Midland ER102 are two of the best emergency survival radios on the market today and have all the features that you need in an emergency situation.
