Category 4 Cyclonic Storm Fani was the strongest tropical cyclone to strike the Indian state of Odisha since Phailin in 2013.
Many thanks to SWLing Post contributor, Ashok Shankar Das, who shares the following post from his blog SWLDAS:
The extremely severe cyclonic storm #Fani recently visited Odisha. It is Peculiar to have a Cyclone in this time of year. Though history says earlier there are some cyclones hit Odisha coast during this summer season.
[…]I have seen several Cyclones including #1999SuperCyclone . Though Super cyclone has done a lot of damage, this one is no less. Wind speed of 200kmph with gust 220 to 250 kmph ripped everything in its path. major damages to infrastructures like power grids, cell towers under construction buildings are name a few.
The CountyComm GP5-SSB
See this SWLING article–I was runner-up in that challenge. My preparation for Cyclone Fani was as per I have described. Well Not all. I have charged emergency light, arranged candles and lantern. Stocked Biscuits and Flat rice. Stored around 15Liters of drinking water. Emergency medicines and fully Charged 3 Baofeng Walkie Talkies.
The GP5SSB I got as a gift from SWLING Post, put new battery in it. I have downed external antennae for HF and VHF. Baofeng handys are quite good as scanner. I monitored HAM band so I could know the situation in surrounding area and also if situation arises I could give a distress call to Nearby monitoring person. But that situation didn’t arise.
HAM volunteers from WBRC started their communication service since 5th May. They Have setup a VHF in state control room at Bhubaneswar, ADM office Puri and Khurda.
Since 5th may onward I was monitoring and in QSO with VU2IPL(Suresh). VU2FTP VU2XRY VU3YDA and VU3OXI are handling the communication between Puri, Khurda and Bhubaneswar.[…]
Thank you for sharing this, Ashok and we’re very pleased that you made it through this extremely dangerous storm well-prepared. It sounds like your community has a good ham radio communications network at the ready as well.
Ashok, you are reminding me that it’s time to dream up another Virtual Radio Challenge along with an enticing prize. I’ll start putting one together! Perhaps I can find a prize at the Hamvention this week. Stay tuned…
In my home town, I’m know as the guy who does ham radio with the Boy Scouts, setting up and operating a full off-grid campsite field station at ARRL Field Day and the Scouts’ Jamboree On The Air. This has been a great learning experience both for the boys and myself, as a great way to determine what works and does not in less than ideal circumstances. Professionally, I work for a defense contractor, with expertise in military radio systems and their power requirements.
On a personal note, I’ve had first-hand experience with emergency radio communications during the Mississippi River Flood of 1993, Hurricane Isabel in 2003, and the Cedar Rapids Flood of 2008. My evaluation of contest entries were based on these first hand experiences, and lessons learned from published accounts of other natural disasters.
The parameters of the Challenge were drawn from these first hand experiences.
“As is often said, stuff happens. Indeed, our modern communication infrastructure is a fragile thing. Let’s imagine that your area suddenly loses power–as well as cell phone and internet service–for an indeterminate period. Home and personal electronics remain unaffected, but must be powered off-grid (without mains power). Moreover, you may be required to evacuate your home…perhaps even on foot….”
“Therefore, how do you intend to:
obtain information about local and world events?
communicate within your local region to assist emergency services?
pass messages to friends and family over long distances?
power your kit for an indeterminate amount of time?”
To make the evaluation of the contest entries as fair as possible, I kept off of the SWLing Post blog during the duration of the contest, arranging with K4SWL to send me the compiled entries with identifying information removed.
In an emergency or natural disaster, as power and communication infrastructure is damaged or degraded, the main avenue for transmission of information to the populace will be the oldest and most common broadcast medium – AM radio.
Most middle-sized towns have a station, and most families have a battery operated portable receiver. The local new/talk station will become a conduit of information on hazards, evacuations, and requests for assistance. This essential component of the emergency communications kit is the item that most people already have.
There are other sources of information that can provide detail that will not be presented in a radio broadcast. A VHF/UHF scanner pre-programed to local utility frequencies, as well as FRS and GMRS frequencies will let you monitor emergency responder traffic, as well as up-to-date NOAA weather broadcasts.
Those bearing an amateur radio license have the opportunity to not only monitor, but to participate in disaster relief. If two-meter repeaters remain in operation, amateur radio operators have often served to supplant or replace overloaded phone services between hospitals, police, and other first responders.
Where the devastation from a disaster is more extensive, or if you are forced to evacuate to a remote location, local communication infrastructure may be completely absent. Shortwave radio broadcasts from around the world can supplement local broadcast media. To handle health and welfare messages from an isolated group, when cell phone reception is absent, long-haul radio capability is required. In many disasters, this has been commonly done using portable HF radio transceivers. When our Boy Scout troop embarks on a high-adventure trip, a satellite phone is packed along. This alternative has the advantage of being able to be used reliably without any skill or licensing.
This raises a valuable point: there has been in recent years a surge of interest in amateur radio among those interested in emergency communication and preparedness.
Amateur radio is a powerful tool for communication, and can be an invaluable emergency resource. However, without the user skills acquired through their frequent use before an emergency occurs, the challenge of operating unfamiliar radio equipment in a critical situation greatly reduces their utility.
Without practice in using repeaters, participating in nets, or passing message traffic, the added stress of having to learn these skills under pressure may make a bad situation worse. In short: if you get an amateur license and equipment, use them.
A further requirement is the ability to power the communication equipment. Power-hungry transmitters will burn through batteries quickly.
The selections available for rechargeable batteries are numerous, but options for charging are somewhat more limited. Thin-film solar panels have recently become an economical power choice for portable operations. Other options, such as hand-crank generators and thermoelectric converters can provide power when sunlight is not available.
With the Challenge entries in hand, it was a matter of evaluating each versus the stated goals of the Challenge. I was impressed by the documentation accompanying most entries, and justification of choices made.
Nearly every entry specified a portable general-coverage receiver with shortwave and SSB.
The Tecsun PL-660 was a popular choice. Radios of this type are very versatile, reasonably economical, and capable of receiving a wide variety of broadcast signals.
Many of the entries included a BaoFung dual-band HT. This is another excellent choice. Although lacking features found in more expensive HTs, they have the capacity to perform scanning, and can be pressed into service as a FMR or GMRS transceiver in an emergency, The economy of these radios makes their inclusion an obvious choice.
Most entrants showed a great degree of thought in their selection of power sources. Many included solar panels or hand-cranked generators to maintain power over long-term operation.
A minority of entries added equipment capable of long distance two-way conversation. For the most part, these consisted of low-cost fixed-frequency QRP CW transceivers such as the Chinese Pixie or Frogsounds kits. The shortcomings of these kits is having the skills needed for proficient operation–thus limiting their utility–but they are better than nothing.
The Winning Entry: Mehdi
One entry took a different approach to long-distance communication; I consider it the winning entry.
The following was the entry submitted by Mehdi:
Here are my thoughts on how to prepare for the virtual Radio Challenge IV:
I’ve already had this idea on my mind, because I live in a densely populated city (Tehran) and the possibility of an earthquake in near future is not improbable, so the least I could do is to be mentally prepared.
I’ve already bought things like torch, portable radio, and even a real US military compass!!
First of all, I chose the Tecsun PL-310ET for this scenario. Why?
I need a light portable radio and it’s got all the functionality I require (AM/FM for local/regional news and SW for international news). I don’t need weather broadcast as we haven’t got that service here. SSB is also not required (found in better models like PL-660). I have also added a 12 pack of AA batteries for it.
The third item is a cheap and small VHF/UHF two way radio which lets me listen to local authorities (fire/emergency/…) and other organizations’ radios and also communicate with them in case of emergency. It can also be operated on FRS/GMRS. I’ve also included two spare batteries. (Because the total price of all is above 35$, they’ve got free shipping).
And about Thuraya phone: I chose it because it’s easier to use and smaller/lighter than a portable HF rig. I have also considered portable HF transceivers before, but they have a few problems:
1- Need good power source
2- Propagation affects it (and regarding propagation, we’re not in a very good time now)
3- Not everyone can operate them easily
4- It needs an antenna to be set up
5- A good rig (even a used one) is more expensive than our budget.
I’ve also selected two spare batteries for Thuraya plus a SIM card.
The sum of all these items is $397.99 and I’ve considered portability, availability and power selecting these gadgets. I also should stress that I have also considered the compatibility and availability of these gadgets in my own country, so it may not be the best match for US citizens. I’m not sure if Thuraya has US coverage, so it could be replaced by something like Iridium or InmarSat. Also, US citizens may benefit from Weather/NOAA enabled radios.
If I were allowed to spend a little bit more, I would include a solar panel charger (about 20 dollars) too.
It’s just the “radio” related part and I will carry other necessary items in my bag (torch, knives, water, lighters, etc)
P.S. My solution is based on some presumptions, most important of them is leaving house on foot. If I were allowed to spend more and I could bring my car with myself, I probably would select a Yaesu FT-817 which operates on HF/VHF/UHF bands and can be powered from car battery and just needs a car-mounted antenna (It can be replaced with all above items).
To a kit containing a BaoFung HT and a Tecsun PL-310, Mehdi added a Thuraya satellite phone. Even though I am a ham radio fanatic with a bias toward HF radio operation, I recognize that the ability to achieve reliable worldwide communication using a device with a minimal operator learning curve gives it a clear advantage for communication in an uncertain environment.
While Mehdi specified a list of battery options for his setup, he was not able include a means of recharging within the $400 budget. He did, though, mention the possibility of adding a low cost solar panel, substituting it for one of the spare battery packs would have been a prudent option.
While Mehdi’s solution is very good, it should be recognized that the satellites employed by the satellite phones do have vulnerability to EMP and CME, as would any other communication method requiring terrestrial infrastructure. I would prefer to see a high-end HF transceiver included as part of the communication package, though this is very challenging within the cost target of the Virtual Radio Challenge. Within that cost constraint though, the satellite phone is an excellent choice.
A very close runner up is the entry submitted by Ashok, who in his write-up described his emergency experience during the landfall of a super cyclone in his home of Cuttack, near the Bay of Bengal.
Cuttack, my QTH, is about 90km by road and about 70km by air. The intensity of devastation happened in cuttack due to Super Cyclone is frightening. Till date those who have face to face with that have never forget the dreaded situation that day.
In the morning at 9:00 AM wind started and power supply failed within 5 minutes. The only way to get news was through radio.
Unfortunately, we were not aware that such a severe cyclone is on the way, so batteries for radio and flash light were not available. My Father and Uncle were worried and wanted to know what is the situation and precautions we should take. As batteries are not available, I reached out to my “junk box”.
I found a IN34 diode an MW antenna coil a 2j Gang capacitor a old telephone earpiece. Immediately I joined them in to a “Crystal Radio” (no soldering just connected those with hookup wires). I managed to receive Local HPT MW broadcast station AIR Cuttack.
Gradually wind condition and rain got worse with the passing time.
In the evening about 8pm I heard the announcer saying “only GOD can help us survive this cyclone–we wish to speak to all our listeners tomorrow, if we survive” and after that suddenly the transmission is broken and nothing is heard. Later we learned that the transmitting tower was uprooted.
Currently I am trying to get a Restricted grade or General grade Ham Radio license. After I get the license I can operate in the HAM bands, but Citizen Band radio doesn’t require a license in India, hence currently I have only one FRS radio (though FRS and CB radios are not popular in my part of India). Still there is a hope that a nearby monitoring station or defense establishment may pick up my signal and may come to rescue.
What I propose is as follows.
1) A very good standalone radio receiver (Eg. the Tecsun PL-660). A World band radio can be useful to get news from any available station nearby. The stations in the area hit by cyclone may not have any transmission facility, hence nearby broadcast stations can relay news about the situation.
Keep dry foods: Biscuits and sliced breads, 4 liters of drinking water
My prior experience says one must be prepared for 3 days survival. To survive in a natural calamity like a cyclone, food and water is a must. 2 packs of biscuit and 4 liter of water is enough for only one day. Next 2 to 3 days can be managed after the cyclone recedes by exploring nearby area.
i) Antiseptic cream 1 small tube
ii) Chlorine tablet for water purification
iii) Paracetamol tablet 1 strip
iv) Anti Diarrhea tablets
v) Anti acid/Gastro regulator tablets
vi) bandages 1 or 2 rolls
vii) clinical alcohol for disinfection
In emergency situations generic medicines are vital for survival to fight odds. these medicines are for tropical cyclone survival.
4) few matchboxes or cigarette lighter, candle
to light up the shelter in the night candle is needed. to make fire to survive cold matchbox or candle is needed
5) A Craftman’s knife
To cut clothes, scale wood for fire.
6) PIXIE like transceiver for SOS use PIXIE transceivers are easy to construct, very small in size and Low power consuming QRP devices. situations like natural calamities or devastation need smaller devices. it also can be powered from a 9v transistor battery.
7) Hand-held HF SSB Transceiver (DK7IH Handheld QRP SSB Transceiver or TJ2B Portable 4 Band)
Baofeng UV-5R VHF/UHF Transceiver
Voice communication is needed as we can communicate naturally with peers at other end and can convey our feelings easily.
Also there is a psychological factor: when we hear a comforting voice we gather our courage and patience.
8) A QRP antenna tuner
Antenna tuners come in handy as we don’t have proper antenna during and after disaster.
9) A very long electrical wire. (Twin flexible wires are also good)
Wires are needed for antenna and also can be used for fastening
10) A 12v 7amp hour maintenance-free rechargeable UPS battery.
this is the prime battery for several purposes.
i) Lighting the place with LEDs 4White LEDs plus 1 red LED in series can be connected across 12v
ii) powering the TRX Both DK7IH trx and Pixie
11) 9v batteries (quantity of four)
I mentioned 4 batteries as a careful guess work and my previous experience of 1999 cyclone. (We were cut off from the world for 15 days!)
With 4 9v transistor batteries and the Pixie QRP transceiver, I can use it in extreme condition.
12) 1.2v NiMH battery packs
These batteries are needed by the DK7IH transceiver, so 1 or 2 sets extra will be nice to have.
13) Solar charger for 12v
To charge DK7IH trx batteries. and also for charging the 12v UPS battery. Can be usable after the cyclone recedes. Cloud cover recedes few hours after landfall.
14) Hand crank or cycle dynamo. (needed if the situation is extreme and not much sunlight) OPTIONAL…
The most heavy parts are 12V 7Ah battery (2 Kg approx), next heavier thing is solar panel around 1/2 Kg.
The Tecsun PL-660 is next 470 grams. So total weight of communication system and power sources combined won’t exceed 5 Kg, Which is comfortable for a back pack.
The above prices are for radio communication purpose only. But survival of a cyclone not only depends on communication. It needs a presence of mind and making the right decisions.
The DK7IH hand held transceiver is a very compact and nice looking rig. I have it in my wish list I guess it wont exceed more than $100.00.
A hand crank genset is good for situations when sunlight is not available. But it can be considered optional.
I have considered the 12v 7Ah lead acid maintenance free battery from Indian market it costs Rs.850.00 which is $16.00 approximately.
So if we calculate the prices of all the materials then it will cost $336.45. If a hand crank generator is added to this list it will go to $447.77
If I am not taking the hand-crank generator then the remaining money i can go for few meters of wire, some biscuits and water bottles for me and other survivors.
Ashok’s setup included a Tecsun PL-660, a Baofeng UV-5R, a Pixie, a wire antenna and QRP antenna tuner, and a homebrew 20M SSB transceiver based on the DK7IH design.
Power was provided by 12v, 7AH SLA, and NiMH AAA batteries, recharged by a solar panel. Ashok also had budgeted emergency food and first aid supplies, which while not required in the Challenge, are still an important consideration for emergency preparedness. While the 20M SSB transceiver is not as reliable for long-distance communications as a satellite phone, it does have one important advantage: it is not reliant on satellite infrastructure that would by impacted by EMP or CME.
As I write this, there is a massive relief effort underway in Chennai India as devastating floods affect the region. There are reports of amateur radio operators providing emergency communication to those affected. Lessons learned from this tragedy will help guide us for future emergencies. Exercises like this Radio Challenge help prepare us to face these very kind of situations.
I would also like to thank CountyComm Government Products Group. Readers should know that Nick, with CountyComm, is a ham radio operator and regular SWLing Post reader. When Nick read about our third radio challenge, he wanted to sponsor our next challenge. Fortunately, I had already started working on a draft of this challenge in the SWLing Post hopper. CountyComm was a perfect fit as a sponsor since much of their product line is used either in tactical situations or for emergency preparedness. Nick went above and beyond the call of duty with his prize package–he has been an enthusiastic supporter. Having a prize makes the whole hypothetical challenge even more fun. Thanks, Nick!
Last but not least, I’m very grateful to our judge, David Cripe (NM0S). Dave is a busy guy in both his professional life and in his spare time. When I approached him about being a judge, he knew it would entail hours of research. This was a blind evaluation–Dave only knew entrants by first name or initials. He spent several days worth of his spare time during the Thanksgiving holidays researching product specifications, comparing, evaluating and picking our winners. He is the most knowledgable engineer I know on this particular topic, too. We’re quite fortunate to have him as a resource for this challenge. Thank you so much, Dave!
Early in 2016, I’ll post another–completely different–radio challenge. Like our other challenges, it is based on actual SWLing Post reader questions. I believe it will be a more accessible challenge for those of you who are new to shortwave and ham radio.
Enter our challenge and you could win this prize package worth over $200 courtesy of CountyComm!
Let’s imagine that your area suddenly loses power–as well as cell phone and internet service–for an indeterminate period. Home and personal electronics remain unaffected, but must be powered off-grid (without mains power). Moreover, you may be required to evacuate your home…perhaps even on foot.
In preparation for this event, what portable radio kit would you assemble?
Submit your answer to this question and you could win a preparedness prize package courtesy of CountyComm!
All entries must be received by November 21, 2015.
We’ve received some brilliant, creative entries in the Virtual radio challenge: your opportunity to piece together the best $200 (US) radio kit you might pack for one year on the remote island of Tristan Da Cunha.
Shortwave listeners are interesting, creative people who do interesting, creative work: they’re scientists, veterans, corporate employees, students, retirees, volunteers, politicians, musicians, inventors, entrepreneurs, engineers, humanitarians, reporters, artists, researchers, sailors, pilots, pirates…and most seem to be travelers. But to say the least, they’re very diverse. The joy of the SWLing Post, for me, is the fascinating readers here and the great variety of questions and comments I receive from you.
On this blog, I often write about selecting the “right” radio for home, boating, preparedness, off-grid living, and of course travel–but sometimes I like to go through the mental exercise of imagining a scenario a little more extreme.
Indeed, I occasionally receive such “extreme” questions from our readers, questions that push the limits of the hobby, demanding highly specific needs in a radio. And, I readily admit, I thoroughly enjoy these questions! They give me a chance–and good excuse, really–to be imaginative and innovative, to push beyond mere practical or monetary constraints to consider unique environments, weather conditions, durability needs, power requirements, and/or resource availability…great fun.
If you enjoy this kind of brain game, too, check out our virtual challenge that follows:
Should you agree to take it on, you’ll need to complete it within two weeks. Why the time constraint? Let’s imagine that your flight leaves May 15th, and you’ll need to make sure you’ve received, tested, and packed all of your supplies by that date.
[By the way, this scenario is based on an actual reader question.]
Tristan da Cunha on 6 February 2013, as seen from the International Space Station (Source: Wikipedia)
Accommodation: A rented room in a native Tristanian family home
Electricity: Mains power via the grid, but you’ll have to expect extended power outages if there is a generator failure
Internet: The island has (slow speed) public Internet, but you will not have access at your accommodation
Your budget: $200 US–which must cover all of your radio requirements (radio, antenna, batteries, and all accessories)
Scenario: You’re on an assignment, being sent to one of the world’s most remote inhabited islands–Tristan Da Cunha, in the South Atlantic (see this overview of the island from Wikipedia)–to undertake research for one year. You’ll fly into South Africa, where you’ll board a cargo vessel for the one-week journey to the island. The maximum amount of luggage allowed by your airline is one carry-on and two check-in bags, both of no more than 60 kg (132 lbs), total.
Once on the island, you will not leave until a ship picks you up 365 days later.
Edinburgh of the Seven Seas, Tristan da Cunha, South Atlantic Ocean (Source: michael clarke stuff)
Tristan Da Cunha has less than 300 total inhabitants, so while there are basic shops and accommodations, these are very limited. Once there, ordering a new radio or accessories will not be an option. Getting your rig fixed by an island electronics repair shop will be possible, to some extent (we’ll assume you don’t possess those repair skills yourself). Batteries are locally available, but very expensive…
You’ll be staying in a small, thick-walled stone cottage with a family and will have your own room, with a window. The family will allow you to string a wire antenna outside, but there are no trees, only heath and shrubs. Additionally, winds are strong and rainfall substantial; sunshine can be quite limited.
We’ll assume you’re starting from scratch, that you have neither radio nor any accessories. You’re allowing yourself a maximum of $200 US for all of your radio gear. Your goal is to have the best shortwave listening set-up possible for your budget and for this situation. Since your radio must be packed in your luggage, you can’t afford the space nor the weight of a large tabletop radio.
Obviously, the more you understand the island and its limitations, the better choices you’ll make for your gear.
You’re limited to a (virtual) budget of $200 US to procure your supplies; ideally, this includes shipping costs
You can select used gear, but must base your choices on reality (i.e., actually find item(s) online and document the price and time of availability). If you “shop” eBay, make sure you’re using the final price, not the current or opening bid. If you do locate something used on eBay, QTH.com, QRZ.com or at Universal Radio, for example, include the link! (Just to add to the fun.)
Your main objective is to listen to international broadcasters, and do a little DXing, of course. FM sensitivity will not be a factor (of course, I’m joking here!) Whether or not the radio has SSB mode is up to you.
We’ll assume that you’re bringing a laptop computer with you.
Remember, you’ll be stuck with this radio for one full year! So choose something you’ll love to operate, and don’t forget your vital accessories.
Note: The limitations of this exercise are simply to level the playing field for everyone as well as to make the challenge a little tougher (and thus more fun!). Of course, they’re open to interpretation, but do try to honor the spirit of the game.
Up to the challenge? You’ve got two weeks–!
To participate, just comment on this post with your suggested set-up, any links, and a brief explanation for your choices.
