Ham Radio Served as Main Link to Disaster Area

SonicSpike writes "A University of Central Florida ham radio operator K4VUD (and founder of their film program) was caught in Port Blair during the earthquake and following tsunami! He and a team of other ham radio operators arrived in the Andaman and Nicobar Islands to setup the region's first ham station 2 weeks prior to the disaster. Once they realized what happened they immediately began transmitting for 20 straight hours using car batteries as a power source. Most cellular and land-line communication was down. His team became the main link to the rest of the world from the region."

      BPL just might spell the death of Amateur Radio. Think about it, for most of us, the original purpose of obtaining an amateur radio license was to

      a) To talk to people in distant places

      b) Perform public service (RACES/ARES, etc)

      c) Be able to fix/build/repair your own radio gear.

      Now, let's see what happens today:

      a) Anyone can plug in a $4 mic, use VoIP, and "talk" to almost anywhere on Earth, no license or self-study required.

      b) Whip out your cell phone. That is unless a disaster hits, and all the cell sites are down, or your 40 min. battery dies. Also the "big news guys" literally take over a cell site. CNN's truck logs in via cell at every major story, and keeps an open line as a backup. If even 200 reporters did this, kiss off any chance of getting a cell signal, since the towers would be overloaded

      c) How many parts inside a modern radio are actually user-servicable?

    well this is a feel good story and all, but I always wonder -- how exactly are these amateur radio operators helping in more than an anecdotal way during disasters? I mean, is it like they're ferrying critical rescue and operations traffic? I have a feeling not, because to do that, both they and the operators on the other side would have to be tied in to whatever government or agency is reaching out to help. And to have that be the case, there would have to be serious pre-disaster networks and agreements set up.

    I mean, this is similar to the relief organizations in the area now -- they keep telling regular people not to volunteer to fly to the region and help out, because what they really want are people who know what they're doing and part of the organization already, and can be deployed. A single ham radio operator on his/her own is not going to be that useful.

    So maybe I'm not really familiar with the true value of ham radio operators in situations like this -- can anyone give a more informed picture?

      This is a legitmate question, but the answer is in the article if you are familiar with ham radio "terms of art." In the article there are references to "helping to handle emergency traffic" and also "pitching in to handle emergency and health-and-welfare traffic." Emergency traffic and health-and-welfare traffic are terms describing two very different types of disaster communication.

      There are four general categories of disaster messages which have the following precedence:

      1. Emergency traffic. This includes messages relating to the immediate protection of life or propery. For example, coordinating the delivery of medical supplies or personnel; dispatching emergency services; relaying vital information for disaster response.

      2. Priority traffic. Generally not as time sensitive as emergency traffic.
      3. Health-and-welfare traffic is the type of messages which you reference where a survivor wants to get word out relatives that they are ok.

      4. Routine. Non-related communications


      So, the fact that the article specifies that they handled "emergency and health-and-welfare" means that they did more than handle "I'm ok" messages. There's an additional clue when the article says that "[o]ur control center was inside the prime minister's official house in his operational room." This indicates that it is very likely that they were handling critical messages until regular communications could be set up.


      Amateur Radio has similar roles around the U.S. and the world in official government emergency response plans. I am part of a volunteer emergency communications team for a major metropolitan area in the U.S. We have our own area and equipment in the city emergency operations center. In the event of a disaster, we become the relay through which all information/reports for 911-type dispatching will come. We form the link to the county and state emergency operations centers, and provide other radio-based services as well. We are offically affiliated with the police department. There are other groups affiliated with relief organizations like the Red Cross and the Salvation Army which provide more health-and-welfare type traffic than our group, but they also handle critical relief-related communications for their organizations. Ham radio is involved in all levels of disaster response communications from the most important to the least.

    A: Very likely. Contrary to your belief, it does not require that Joe Ham have a lot of power or a huge antenna on a tower to communicate with the other side of the world. Nor does it require repeaters on the HF frequencies.

    I've been an FCC licensed Ham since 1958 at age 12 and operate only with low power (QRP to us hams) as a challenge precisely because making long distance contacts was too easy with even moderate power (say 100 watts) and modest wire antennas. I've communicated directly with Japan and New Zealand from my car in Illinois using a 4 watt transmitter and a 4 foot antenna on the trunk. If you get up to around 100 Watts and a reasonable wire antenna hung up in the trees in the back yard, you can very easily talk anywhere in the world, given reasonable conditions.

    What good is it from the other end? I was with Project Hope in Tunisia in 1969 and provided daily "phone-patched" phone call service to the staff of about 150 people so they could stay in touch with their families back home, without having to pay the $13.00 for the first 3 minutes that the landline cost. It made a huge difference to the people on the hospital ship. In disaster situations, it's orders of magnitude more important. Some of my fellow hams here in the states provided similar communications for military and Antarctic bases for years.

    To learn more about Amateur Radio, visit the ARRL website. ARRL Oh, and please, please, do not lump us in with CB folks, as nice as some of them are. Hams are tested and licensed to FCC standards prior to being allowed to put their transmitters on the air.

    On the topic of Ham radios during disasters, I would like to bring up something that annoys me to no end...

    Why in the hell is it that emergency services aren't equipt to handle anything but a normal day? When some idiots have assault weapons and body armor, police are practically helpless (they got lucky, actually). When there is anything larger than a house fire, firefighters don't have the equipment, training, numbers, etc. When there are real emergencies, police, firefigters and ambulance services don't have any working and practical communications equipment at all. It seems the more developed our country becomes, the more emergency services depend on the very infrastructure that will be first to fail when it's really needed...

    It's clear that local (city/county, sometimes state) governments are to blame. They cause flood damage by approving roads to be built, but don't account for drainage, and allow homes to be built in the obvious path of flood waters. In the worst areas, they may even build storm-drains, but do nothing to keep they clear, rending them completely useless wastes of money. Emergency services in flood-prone areas never seem to have the equipment that would make it easy to perform the necessary rescues, meaning people die, money is wasted, etc.

    They allow homes to be built near wooded areas, prone to major fires, and don't do the slightest bit of maintenance on those areas to prevent major fires. I've heard of only one city in Southern California that spends a small ammount of money to clear brush, why don't the rest? Firefighters are helpless against forrest-fires, and yet, the preventative controlled burns (the method previously used) have even been stopped.

    Hospitals are now (finally) required to have a generator, but only required to have enough capacity to stay up for a short time (a couple days IIRC) when blackouts can last far longer. Besides hospitals, emergency services depend greatly on the power grid, and rarely have the generators they need (typically short-term battery power) so they are the least able to handle emergencies, when they are needed THE MOST.

    The point of all of this is simple... What the hell is the good of having a local government, if they aren't taking care of the real necessities? Local governments are needed for the very things they are now neglecting to do, so why not get rid of them all-together? The basic things can be handled by the state government anyhow (police, fire, medical, schools, etc) so if we aren't going to be well-served by local governments, why keep them on as a leech, taking our tax dollars and spending them on trivial things few of us want, and most of us feel like we are getting ripped-off by?

    Personally, of course I would prefer if local governments would just start doing their jobs, but since that's not happing, I'd like to see them abolished, rather than keeping the status-quo. What good are they, as is?
