Ham Radio Served as Main Link to Disaster Area 380
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."

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 [projecthope.org] 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.

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?

Here is an example of how completely innadequate car batteries would be. I have a kiln/studio that until recently, had no power. I used a 12v deep cycle battery to power an inverter, light bulb (high efficiency flourescent), and a mini-itx based computer. If I ran only the light, I would get about 12 hours usuage before my charge fell below 50%. - that's when running nothing but

Just be thankful the world is reacting at all I say. If this had not have been a natural disaster, but rather another genocide or brutal regime killing people, the world would still be sitting on its collective hands watching the death toll rise. Natural disasters are easy to deal with. No messy issues with who is the "good guy" and who is the "bad guy", just throw money at it to prove how much you care.

Why does that matter so much? Being a compulsive media watcher, I saw this whole ordeal unfold and it appears to have been meant to add some little sub-plot seeking to get folks to give up some money for a good cause. Since when has encouraging people to help been a bad thing? If stupid marketing sells more donations, then they should keep at it! Lives are saved regardless

2. Maybe the aussies actually had to load stuff on the ships. You know...stuff that people might need, like medical supplies, water, blankets. Does no good to send empty ships.
3. It takes quite a while for a carrier battle group (the Abraham Lincoln) [pacom.mil] to steam several thousand miles. Unless you know of another way to get helicopters and 15,000 navy people across a few thousand miles of open ocean.
It seems to me you're bitching just to be bitching.

You think there are cargo ships and helicopters loaded up 24/7 with crews, appropriate supplies and doctors just waiting for a disaster to strike?

The ships and helicopters are in the US Navy. They were geared up for a military mission. Once the White House decided to change their mission, they likely had to get provisions for the new mission. Tents, portable generators, etc

Well do you suppose they just have big old ships full of disaster relief supplies sitting dockside in Australia? Or do you suppose that they have to be fueled, loaded up (once they figure out what types of supplies will be needed) and sent on the way?

This already exists, more or less. Most countries have their own military, with aircraft and helicopters. What you propose would have to be a fleet every 500 miles or so, all the way around the planet. Helicopters are notoriously shortlegged. And quite often, they are the only thing that can get to the affected area. No runways exist, or are left after the disaster.
In this case, such a fleet would have been more useful for evacuation purposes. Seismographs recorded the earthquakes long before the tsunami hit populated areas.
Radio and telephone are far faster. And efforts were made in this case, to little effect.
No transport systems existed in those areas to get people out, but a first response system may have been able to get some out and deliver warnings to others. Enough that perhaps we'd be seeing death rates a tenth (or less) of those we actually have.
How many people can you evacuate via helicopter? 20 each? How many helicopters to evacuate 100,000 people in an hour?

In 5 years (assuming there isn't another crisis of this magnitude) people will largely forget about ham radio and its function especially as an emergency communications network.

I think you're a troll... but...
I'm fairly certain that in an emergency you can use whatever mode of transmitting you like in any segment of the band. I'm not certain of this, but I'm sure someone here can tell us for sure.
Regardless, I would think that CW would be the best mode of operation due to the fact that you could use less transmitting power (and conserve your battery) and still get through.
