Ham Radio Fills Communication Gaps In Nepal Rescue Effort
itwbennett writes: Amateur radio has stepped in to fill communication gaps in Nepal, which is struggling with power outages and a flaky Internet after a devastating earthquake on Saturday killed over 5,000 people. Though 99 persons have ham licenses in Kathmandu, about eight use high-frequency (HF) radios that can transmit long distances, while another 30 have very high frequency and ultra high frequency sets for local traffic, said Satish Kharel, a lawyer in Kathmandu, who uses the ham call signal 9N1AA. The hobbyist radio operators are working round-the-clock to help people get in touch with relatives, pass on information and alert about developing crises.
Do we really need a story about ham radio after every disaster?
Yes, because its an efficient indicator of the immediate scope and nature of a disaster. if the most critical and arguably resillient communications systems have finally failed, Ham is your red-flag indicator that the situation is dire.
I'm sure it's being used, but not to the extent of official radio communication.
Thats exactly the point. Ham is being used because Official or commerical communications systems are either damaged, destroyed, or overwhelmed beyond inteded or effective capacity. If you're in the united states the equivalent official communication would be the Emergency Alert System over a VHF repeater, if ones still standing. If not, Hams take everything from presidential to local law enforcement messages to where they need to go in a structured, orderly manner.
"People communicating by any means possible," is not news.
People communicating by any means possible is a normal society with twitter, cellphones, and wifi. People reliant upon analog and digital communication outside thestructure of a commercial ecosystem and in lieu of direct government correspondance is news. Ham operators build and run antennas, configure messaging relay and repeater systems, repair existing infrastructure, assist in dispatching emergency services and handle every communication thats needed in an emergency from local to state and even international SOS for emergency assistance. The point is when you're now reliant on Ham in any context to assist in a rescue effort, the outlook for existing infrastructure is very bad.
Good people go to bed earlier.
In 1998 there was an ice storm that struck Upstate New York. Hams were virtually the only source of communication as official communication channels ran out of gas (in many cases literally) after a day or so. I sat in a Firehouse with my own equipment relaying communications from ambulances (where another ham was riding along) to other base stations in nearby towns. We did most of this over 2 meters.
Hams were absolutely crucial because we could move in and quickly setup and operate additional equipment. I know times have changed....but every time I look at the state's disaster readiness plan hams would be needed again.
I think you are over estimating the ability of official channels to be ready to function on their own for weeks at a time.

There are in general two kinds of operation of ham radio. First is local communications - local rescue groups using hams to help communicate and coordinate between groups on the ground and HQ.
There's also the longer distance communications - these guys get the signal out so someone in an area not affected by the disaster can pass on messages and whatnot. Think more along the lines of "I'm safe and sound" type messages being passed on to family.
The problem is power line broadband basically makes the long-distance communications less reliable. I mean, given Nepal's economic conditions, sending out "I'm safe" messages usually mean transmitting to India, where the infrastructure works fine. Powerline broadband would be working as well, which means your message will not be received because the receiver can't hear your message over the noise.
Power line networking or broadband generally affects long-distance HF communications more so than short-range VHF/UHF comms. And that's bad because short range would mean the power and infrastructure is down so it's not a problem. But you want to pass your message to places unaffected by the disaster where there IS working infrastructure, and then you have interference.
And that's the beauty of ham radio that blows people's minds away - it's not just about people talking to people in a city, but around the world - it spans the ability to talk to people from your neighbourhood or city to around the globe. Most people are fascinated because most of them only see extreme short range communications - a few miles at most for a cellphone to the tower, to a few tens of feet for wifi and Bluetooth. Telling them that it's possible to actually go around the world on wireless...
Yes, because everyone not affected seems to assume that stuff like the Internet and cellphones will kill ham radio. Yet I'm pretty sure that while in normal circumstances you could get access to the Internet, and yes, the vast majority of people have cellphones, well, guess what? That stuff's not working now, so now what? Bit hard to use the Google or Facebook "I'm safe" feature when you can't get online now...
Call a friend, or text? Pretty hard when the towers are overloaded and maybe even in states that would appear to work, but not.
And that's a problem because people assume that because in the normal case it's not needed, it's obsolete. I'm sure a lot of people on /. wonder about AM/FM radios given that you can stream Pandora and other stuff off the internet.
And yes, ham radio is often official radio communications methods - many rescue groups use hams to provide communications between teams on the ground and HQ, or even to provide a way to tell someone else outside the country to relay messages onwards. And local government also often uses hams for emergency communications - the ham radio infrastructure may often be better than what their official radios have.
