To have food and water stored in the event of an emergency is smart, but what about communications?  If you are without power, how will you be able to stay connected with the outside world and get news about what’s happening?  Having an emergency radio on hand with the rest of your survival supplies is the smart choice.  They’re available in a wide variety of styles and can be cranked by hand, or solar powered, or both. Even in the relatively benign event of just being without electricity due to a power outage, a radio you can charge manually or with the sun’s light can be of great advantage if you want to listen to something other than silence.

Short-term emergencies have shown the limitations of using cell phones to coordinate with each other. Cell phone communication has a lot of vulnerabilities that make it a poor solution for widespread or long-term emergencies. Heavy winds or flooding can disrupt the cables between towers such as during Hurricane Sandy. Cell towers require AC power to operate so if they don’t have an automatic backup system, they stop. Cell phones require satellites, which are vulnerable to hackers, physical attack, or solar storms. Now don’t get me wrong, for day-to-day emergencies, such as getting a flat tire, a cell phone usually works pretty well. A lot of people grew up watching BJ and the Bear and they remember seeing all the truckers talking over the air with each other. One of the big reasons your range is very limited with CB vs other systems is that they’re limited to 5 watts input which is about 4 watt out.
You might think that you could just hack into your ham radio and pump out more power, but the FCC goes after people who do that (just a few examples). Another big problem is that just like cell phones, they rely on the satellites to function so if the satellites stop working, then so do the satellite phones. If you have a true GMRS radio, you may be able to tap into a repeater, which will expand your range to possibly hundreds of miles, but the repeater obviously has to be running, and you have to be within range of the repeater for your radio to hit it. Basically, if you’re considering one of these radio systems for emergency use, go with a true GMRS radio and get the license. Ham radio is the go-to communication system for pretty much every emergency response system and is what MARS (the Military Auxiliary Radio System) and ARES (Amateur Radio Emergency Service) both use, as well as many search and rescue and other emergency groups. One of the nice things is that a lot of ham radios can reach the national weather system (NOAA) frequencies. Here is a list of emergency radio frequencies that you should keep in mind when both looking for radios and coming up with your emergency communications plan. Here is a large list of different frequencies that you could use to put together a list of channels to follow during an emergency or other times.
Ham radio operation requires a license, but as you can see in this article, they’re easy to get. A big part of getting your signal out and hearing others is the antenna so if you get a handheld, I’d suggest upgrading the antenna like I mentioned above. There are a lot of repeaters around the world that can help you transmit long distances with just a little radio. There are even repeaters that use the internet so if you tap into a repeater and type in the address of a remote repeater in another country, what you say on your little radio will blast out to that point on the other side of the world. There are several books such as Low Profile Amateur Radio: Operating a Ham Station from Almost Anywhere that can show you how to do these (which is a great book, by the way but good luck finding a copy of it). With the proper knowledge (which you can pretty much only get with practice), you can make a radio out of stuff you can find pretty much anywhere that will transmit on frequencies that you can reach other people.
Obviously, the more experience you have with radios, the easier it’ll be for you to do something like this. If you want to get started learning about ham radio as an effective emergency communications system for you or your family, check out the Prepared Ham Forum. If you don’t have a ham radio license yet (or actually, even if you do), you should look at getting an emergency shortwave radio so you can listen into weather bulletins etc. So, there are many different ways to communicate during a disaster situation or if society collapses but for the most flexible and effective way, you should seriously look into getting your ham radio license and start playing with it. Either way, make sure whatever you do that you come up with an emergency communications plan beforehand.
My goal is to help families to understand how to intelligently protect their family and their way of life against real threats, without all the end-of-the-world doomsday crap. I hope you’ll consider posting an article on the integration of your Yaesu FT-857d into your BOV. Might also consider a rockmite tiny transceiver, can fit min an altoids can (without options). Great article, Amateur Radio is something I have been thinking about getting a licence for, and really interested in that book, Low Profile Amateur Radio: Operating a Ham Station from Almost Anywhere, it sounds like it could be just the thing for the area I live in. I would just like to add that I would not recommend Baofeng radios due to their quality control issues. Hate male coming your way Hate male coming your way (Craig Ferguson Reference) Seriously though, The time of ripping the parts out of the HUGE tv console and building a transmitter are long gone (Ive done it many times in my youth). I’m curious to know if you can make SatPhone to SatPhone calls if SHTF and power was down across a huge area, say the entire east or west coast. Satphones would still work unless something from the ground causes them to shut down like a command signal. It’s hard to fathom the extent of the devastation in the Philippines following Typhoon Haiyan (also known as Yolanda) last week. In light of this, I’ve been trying to get a sense of how radio might be aiding these communities.
Additionally, HAM radio operators in the region are being asked to assist families hoping to make contact with loved ones in the Philippines.
Jennifer Waits is co-founder of Radio Survivor and is its College Radio and Culture Editor. Family friends looking for any information concerning Elise Bondesto in the Biliran Provence, in town of Catmon, in the Phillippines after the storm. More than a week after being hit by Typhoon Haiyan (Yolanda) in one of the worst natural disasters in recent history, survivors of the central Philippines have basic needs of food, water and medicine, shelter, evacuation, communication and power. The Philippines Amateur Radio Association (PARA) and its Ham Emergency Radio Operation (HERO) network continue providing emergency communications, and at the request of authorities starting to expand its locations and facilities. Ramon Anquilan DU1UGZ, Vice Chief Operating Officer of PARA, confirms that HERO stations are continuing to work. Working with the National Telecommunications Commission (NTC), the National Disaster Risk Reduction and Management Council (NDRRMC), it is looking at potential sources for needed communications equipment.
Ramon DU1UGZ said, “The NTC has requested that the coverage from Borongan be expanded, to the adjacent town and so on. Lester DV5PO is expected to be given more diesel fuel for his generator so he can continue supplying vital information. He said in one of the worst hit areas of Tacloban that has lost 90 per cent of its buildings, the Negros Oriental Radio Assistance Dumaguete (NORAD-7) team is on its way to provide an additional HF station. There are two repeaters in Tacloban with no power, so we need alternative energy – batteries and solar power. PARA and its HERO network have a long task ahead as it slowly gains the necessary resources and recognition for the emergency communications.
In some good news, Trent Hays DW5HT who has relatives in the US has been found safe and well, by RADNET 5, in Palo, Leyte.
The Emergency Communication is the communication rendered when an aircraft or vessel becomes embroided in a dangerous situation, while the Safety Communication is the communication rendered when there is a need to prevent navigation accidents.


This is a type of radio communication for navigation utilizing the radio wave and estimating the aircraft, vessel position or its direction and distance against a radio wave source point. This is a self-sustaining radio communication rendered between a coast station on land and a ship station, or between ship stations themselves. This is a radio communication rendered within or around a harbor in order to control the navigation of any nearby ships, move those ships, and secure their safety as well as human safety in an emergency.
Distance Range: This depends on the antenna power or whether it is in the day time or late evening, while a possible distance can be about 300 km for the Medium Frequency and about 500 km for the Intermediate Frequency. Modes of transmission: 2 cycle single message transmission mode or 1 cycle single message transmission mode.
1WDSB was institutionalized in July, 1955 as the cordless telephone system for small fishing vessels, and SSB was established in November, 1960.
This was institutionalized in June, 1983 for the coastal fishery and leisure ships with the demand for the wireless communication, leveraging both the wired and wireless communication equipment on the coastal station to connect to the public line, enabling the direct communication between the vessel and the land-based resources such as search and rescue or medical institutions. This was institutionalized in September, 1964 and is called "International VHF Cordless Telephone" using "the frequency band between 156MHz and 174MHz" listed in the table of the S18 in RR appendix, and is utilized for some purposes including harbor service communication, electrical communication service, navigation service, and distress safety communication. This cordless system was institutionalized in December, 1991 to spread the wireless system to pleasure boats and other types of vessels navigating only in coastal waters, using a part of the frequency of the International VHF, whose wireless equipment is divided into the deferment and portable types. Marine VHF also enables ship-to-ship communication, communication with leisure-purpose coastal stations, the receipt of navigation alerts and weather information, communication with the Maritime Safety Agency in emergency, and communication with large vessels. This was institutionalized in June, 1986 to spread the wireless system to pleasure boats including motor boats and yachts, and is principally used by the Small Size Safety Association, Inc. This was institutionalized in 1988 (official name: Fishery Area Information System) to be used by such small-sized vessels operating in the coastal waters that have too complicated a body structure to be loaded with the wireless equipment or have no power generator a board. Each of the 4 satellites is distributed over the equator above the Pacific Ocean, the Indian Ocean, and the Atlantic Ocean (east and west), so its service area is targeted as the entire sea area (within the latitude of 70 degrees) except for the polar regions. One coastal ground station is made to be the Network Coordination Station (NCS) according to the sea area and type out of lots of coastal stations, and completes tasks including the assignment of the frequency for the communication in the appropriate sea area.
This service was initiated in March, 1996 to succeed the service of the coastal cordless telephone ("Ship telephone" which ends its service on March31, 1999) and expand its service area, and complement the service area of the ground system portable telephone. This is a system that targets a buoy with in-built wireless equipment to receive radio waves emitted from there and measure their direction between the ship and other points. This is a kind of the ground radio determination system and one of the hyperbola navigation systems that determine the point from the intersection point of the hyperbolas measured by the difference of the pulse wave arriving time.
Loran C is a system evolved from the A mode (1,750kHz - 1,950kHz: already abolished) put into use in US in the 1940s and uses the radio wave of the long frequency band. The Loran C in Japanese waters is currently operated under the Maritime Safety Agency and by Korea after it was transferred from the US Coast Guard in July, 1993. This is a system which measures position by receiving the radio wave from the military navigation positioning satellite NAVSTAR developed and managed by the Pentagon.
4 GPSs are placed on each circle orbit with the tilt angle of 55'6" at the altitude of about 20,000km. This is designed so that more than 4 satellites can be within the visible range all the time and the distance of each satellite can be measured by selecting 4 satellites randomly and receiving the time signal from any point on the earth. This is a radio beacon targeted at the medium and short distances utilizing the radio wave at the medium frequency band.
It sends the beacon sign and long sound of its own station at a regular time interval and the vessel measures the direction by receiving the corresponding radio wave by the radio direction finder. This is a radio beacon to send the sequential pulse received by the vessel radar (operation initiated in May, 1969). The position of the emission station is shown as a dashed bright line from the center towards the station on the vessel radar at 9GHz.
GMDSS (Global Maritime Distress and Safety System) is a system in which the alter emitted from the vessel in distress, without regard to the sea area, can be received with centainly by land rescue agencies or nearby ships using digital communication technology or the satellite communication technology, instead of the past Morse communication, enabling the search rescue activity which combines the land-based rescue agencies and the vessel as a rescue unit. Depending on the navigation area, the vessel scale, and other factors, the following equipment is to be loaded. Bidirectional cordless telephone, Bidirectional cordless telephone for the vessel and the aircraft, Digital selection call-specific receiver for the medium, high, and very-high frequencies.

If you found yourself in the middle of a wide-scale disaster such as a hurricane or other catastrophe and you had no government coming to help for a while, how would you communicate with your family or others? Keep in mind that a lot of towers are just glorified antennas on the tops of buildings or mountains and backup power, such as an emergency generator, is a very short-term solution.
Your cell phone connects to it via Bluetooth and an app, and the signal is sent and received through an encrypted radio signal. CB radio is definitely more available during an emergency but they have a lot of limitations. In non-emergency life, you have to be concerned that the FCC will go after you if you transmit on a frequency that you’re not allowed to operate.
These people are typically in tune with dealing with emergencies or working with communicating with people in different scenarios. An inexpensive Baofeng UV-5R handheld that I keep on my Harley, a great Yaesu VX-6R waterproof handheld with an upgraded antenna that I keep in my bug out bag, and a portable Yaesu FT-857d radio that I can run off a 12v battery.
Keep in mind also that if you get a Baofeng that their antenna connections are different so you’ll need an adapter in some cases. Basically, a repeater will listen to the little radios in its immediate surroundings and then blast the signal out for hundreds, or thousands, of miles. Antennas can be made out of flagpoles, ladders, fences, railings, and a lot of other things in plain sight. Not only is this useful to hide your antennas, it could seriously come in handy if you had to make an antenna in an emergency. There are several groups that use ham radio for dealing with disasters or for search and rescue. The cool thing is that it doesn’t require a power source and is made from simple parts like a pencil and razor blade. The good thing is that they transmit over a HUGE frequency range so pretty much anyone nearby is gonna hear it. You also have to learn Morse code or create your own in order to have anyone have any idea what you’re trying to say. The Safe-T-Proof radio is a great little one to have because you can charge it with a hand crank or the solar panel, it has a flashlight and a cell phone charger outlet on it too. It’s a great hobby and one that could be the difference between finding your family in an emergency or losing them.
I drive an 06 TJ (Wrangler) for ONE of the vehicles ( and THREE grand Cherokees for the other drivers as the trailer is too big for the TJ) yeah we have a large crew to transport. Last year several officers (including me) were called up by my department to go to Moore, Ok. In the event of a disaster, we have one person everyone checks in with, and they keep a tab on who is ok and who they haven’t heard from. I own three of these radios and each one has a QC issue that makes them not dependable for an emergency situation. I’ve used it in the field every few weeks for the past 6 months, it has held up great. The three Amateur licenses are: Technician, General, *Extra* (vice Technician, General and *Amateur*). Just so no one sends me any "hate" comments for adding my insights… I LOVE this site and think there is a LOT of GREAT info here!


Thanks B24, I sometimes write these on my iphone or ipad so I miss stupid details like that so what I mean to say and what I end up typing sometimes don’t always match. As long as the satellites themselves are still functioning, which is a big assumption, I know… SatPhone to SatPhone calls should be fine? More than 10,000 people are presumed dead, towns are demolished, and communications systems have been disrupted due to power outages. Among HERO reports was news of the official pre-emptive evacuations along exposed coastal areas in the hours before the typhoon arrived.
The Saipan Tribune reports that the MDX Amateur Radio Club is holding a ham radio operators meeting on November 13 in order to help. If you know more about how radio stations and amateur radio operators in the Philippines are assisting citizens following this devastating storm, please let us know in the comments. She's fascinated by the culture of radio and has visited more than 100 radio stations in the United States and in Ireland.
Asking all Amateur Radio Operators who make contact (with any other Amateur Radio operator in on near the town of Catmon) to please spread the word. I intend to replace the old radio that Nathan DU5AOK is using from one of the units that ARRL is sending,” said Ramon DU1UGZ. A HERO station, part of the club ACCESS 5 in that area, has not been heard from since the typhoon hit. As for the High Frequency, it's possible to have a distance from several hundred to several thousand kilometers, and by selecting the optimized frequency utilizing ionospheric reflection depending on the season or the time of day, it can realize worldwide communication. After 1965, its popularization spread rapidly with the miniaturization of the equipment and the financial aid of the subsidy, etc.
Marine Community Horn uses the frequency at 400MHz and adopts the MCA mode, securing the call confidentiality and enabling group calls or general calls in emergencies. As the positions of those 4 satellites can be measured, the time deviation for the user's 3D position and time can be estimated with those parameters. This is a pretty long article that goes into some good detail, but if you want the short answer, this is what you need.
A quick look at some of the things that went on during Hurricane Sandy in NY will show that the government has a lot to deal with in addition to just trying to get your cell phone service back up so even though that was a pretty short-term event, it caused a lot of problems.
They’ll be pretty useless if the national grid goes down due to a cyber attack, EMP or CME, which is actually a lot more likely than you might think.
For you to be ready for a SHTF scenario, you need to have the equipment and practice with it in order to make sure you’ll be able to get through. This can be pretty complicated so it’s best to get a good book on antennas and propagation, and work with more experienced people to help you get going. Because of the range ham radios can get, it’s a LOT easier to get a hold of someone during an emergency.
Obviously the repeaters need to be functioning to do this but people who have repeaters are usually up on emergency communication and will have backup power systems. The two biggest are Radio Amateur Civil Emergency Service (RACES) and Amateur Radio Emergency Service (ARES).
Suffice it to say that with all the wires and old electronics laying around, making a simple radio receiver is pretty simple.
But, being new to amateur radio, I need some tips on what to look for in a mobile radio, antenna, antenna tuner, and any other considerations. Anyway the main body is under the seat, the mic connector is dash mounted via a simple plastic clip I made to hold the connector, the control panel is mounted on the dash dead center above the stereo and an external speaker with housing is mounted to the windshield pointed into the vehicle so it can be heard even when the roof is off the jeep. Get in touch with your local ARRL member club for licensing, training and just plain old help. We also have a backup person in the event that a disaster strikes the primary person’s area.
I see too many reviews where people like the radio based solely on the price alone and ignore all the other factors that make these radios a poor choice. Your comment is VERY valid, and I would personally like to hear from more people on this, in specific, WHEN they purchased their radio, any dates marked on it, and nay issues if any, other than the programming. In an incident a couple of years ago the DC region experienced a large area outage of the ground phone system.
Others are banding together in order to help families reach loved ones in the Philippines by radio.
She is passionate about radio history and is a Research Associate on the Library of Congress' Radio Preservation Task Force. This will mean a VHF repeater is available to a large portion of the affected site of Samar,” he said.
WDSB is, in particular, small-sized and easy to operate, so it spread at the fastest rate as the cordless telephone system for small fishing vessels. The Differential GPS has been operated since April, 1999 as a higher-accuracy positioning system. GPS has been operated since December 8, 1993 when the Pentagon submitted the declaration about the official operation for public welfare. In a lot of cases, the only backup power available is a bank of batteries that stop charging when the main power system stops. As such, even though they’re an improvement, they have a lot of the same limitation on power and range. The lower license will get you started but you really need the higher licenses if you want to communicate around the world. These people are also extremely resourceful so even if they don’t have a working radio (such as after an EMP pulse), they can make one. I can very easily pull everything and put it back as a single box type radio and move it to one of the other vehicles easily.
Not to mention programming a Baofeng is a real pain unless you use CHIRP software which is free and easy to use. A long-time college radio DJ herself, she hosts a weekly show at KFJC 89.7FM in Los Altos Hills, California.
It goes in a loop up through whatever frequencies you tell it to and it stops if it hears someone transmitting. They can also be made to use power from the signal itself so they don’t all need anything else to power them. Quite frankly, anyone as a member of a group, who have these radios SHOULD program them with the software, so that they are all the same, so that if one persons is damaged another can hand them theirs and all settings are the same…. Baofengs and Wouxun's (yes… they're made in China) are DAMNED good radios when you consider their price! Radio communications poster Mobile Communications & Health Booklet Introduction Radio communications are a part of everyday life in today's society. High powered systems are used for television and radio broadcast, usually from a single transmitting tower in an elevated location. Medium powered systems are used for two-way communications typically from a repeater tower to vehicle radio systems like emergency services. Low powered systems are used for mobile communications and rely on a network of transmitting sites like mobile phone base stations.
There has been a lot of research conducted worldwide to investigate possible health effects of radio communications and wireless technology.
