If you have a disaster in an area where there are few hams and those can’t operate (themselves victims, no generators or no gas for generators, batteries dying), then it doesn’t matter how many well-intended hams there are across the rest of the world. Ham radio is usually the first responder communications mode when the commercial means have failed in the initial stages of the disaster. Now, well into day three, there are many commercial facilities getting in place including mass media with satellite stations.
It may turn out that ham radio emergency communications don’t have much to do for Haiti after all, but you would think that the welfare inquiries are still yet to come. With a capitol city of 2 million in ruins with many foreigners there, the inquiries are bound to flow.
