Ham Radio Operators Are Heroes In Oregon
An anonymous reader writes "We all know the impact that Ham radio can have in emergencies, but that often slips by the public and the authorities. Not so in Oregon, where a day after getting inundated with torrential rains and winds and suffering from the usual calamities those cause, Oregon's Governor called the local Ham radio operators heroes. When discussing how the storm affected communications, the governor stated: "I'm going to tell you who the heroes were from the very beginning of this...the ham radio operators." Kudos to the Oregon Ham operators for helping out in a bad situation, and getting the recognition they deserve."
A friend of mine (Randy Cassingham of This Is True ) is a HAM radio operator and he's helped provide communications for emergency responders during disasters near where he lives in Colorado. When the chips are down, it seems that radio hobbyists are ready, willing, and able to help out. It's nice to see that they're getting some positive press.
Hopefully much of this thread will be kudos for Ham radio operators around the world. A lot of them use their powers for good more often than you might think.

I live in Oregon, and let me say, things are still a huge mess around here. Although I personally didn't need rescuing (although someone I know did!), I must say that the HAM operators are an invaluable asset in an event like this. On the coast, communications are still spotty, if existent at all. There was an article in the Oregonian today about how some places on the coast don't even have 911 service, since all of the fiber links for phones are out, and the 911 center doesn't have power anyway - the gas for the generator ran out. It's situations like this where HAM radio operators are particularly useful.
It's still a mess out here. Lots of roads are still closed - Interstate 5 is closed in Washington, effectively cutting off all transportation between Portland and Seattle. Thousands of cars, and most importantly, trucks, travel[ed] this highway daily. The train tracks are closed too, so there's no amtrak or freight trains. I guess we'll just have to wait and see what happens... things are improving, but in no speedy fashion.
You mean something like Packet Radio

That's the problem.

Guys like me (50 years old) don't care to, or are able to, do 5 WPM in Morse code. And as far as that goes, learning Morse never made sense to me anyways, not since the advent of the PC. Hell, I've had an Icom 735 for over 25 years without a license. I like to lurk.
So how do you attract new blood to an activity that's waaay too geeky to begin with? Kids aren't going to bother learning Morse when they can use a program to do the same thing - why would they bother?
So faced with either keeping the hobby "pure" and watching it die out as the oldtimer's keys go silent, or conceding to reality and making membership more attactive to younger folks, which would you choose?
But you're right, it's definitely not the same as it was 20 - 30 years ago.
I dream in binary.
Also, disasters strike in many different ways. It's conceivable that there might be an occasion where the only viable communications medium you have is boolean (a carrier wave with no microphone or modulator circuit, or hammers and pipes in a cave-in, or whatever.) If that's the case, it's Morse or nothing.
Ham radio operators pride themselves on being able to communicate when absolutely nothing else works, and the world is crashing down (or blowing up) around them. Morse is another tool in the toolbox.

Link for those (like me) who aren't familiar with the story: James Kim.
Sure, having a basic radio could have saved James' life. So could have a GPS, or if the gate had been locked, or if he hadn't decided to leave the car, or if his family had taken the train. Anybody can think of dozens of ways he could be alive. Tragedies like this are always the result of a long sequence of events going wrong -- if any had gone right, it would have been avoided.
That's not at all specific to ham radios, though. Ham radios aren't magic, and won't solve every crisis. It's just the nature of tragedies.
Why bother going through the center of the Earth when the ionosphere can easily bounce radio waves.

Myself, I stick mostly to slow but useful 1200 baud AFSK on VHF. When you're passing things like short text messages, telemetry, and position reports, you don't NEED huge amounts of speed. What you need is a system to get the most critical information to where it will do the most good. And 1200 baud has a big advantage in that you can use it over damn near anything that'll pass a voice signal. You can fit an entire modem and protocol stack in a $2, 8-bit microcontroller, too - no fancy ASICs or DSPs needed (see my link below).
As for the long-distance HF communications people usually associate with ham radio, there's PSK-31 which is a very robust and efficient mode designed for keyboard-to-keyboard use. It's slow, but works when almost nothing else does. It can be encoded with the above-mentioned MCU (I do that for propagation beacons and such) but most people just use a sound card and PC.
Pactor III and other modes give you speeds suitable for email on the HF bands, and they're used for that quite a bit.
Ham radio in emergency situations is less about fancy toys, though, and more about having people with the training and knowledge to be able to use them, and to improvise when things go wrong. That's another reason I stick with relatively low-tech stuff - I'd rather build low-cost devices that can be kludged into doing all sorts of useful things than to focus on finicky, expensive, cutting-edge stuff that's going to fall apart when the fecal matter hits the air circulating device.
Yes, there are a lot of crusty old guys on the radio. But keep in mind that ham radio is what nerds did BEFORE computers and Slashdot, and a lot of them remember that spirit, even if they've fallen behind the curve a bit in technology. There's also a growing number of young hams developing exciting things like GNU Radio, and the open source philosophy is increasingly prevalent in the community. I'm certain that in the next decade open source will be THE major driving force in the hobby.
In the end, it's really just a return to the hobby's roots. There's always been a great deal of information sharing and experimentation, but much of that spirit has dwindled in recent years because of the aging population and the increasing complexity and manufacturing costs associated with modern gear. Open source software, plus DSP, FPGAs, fast computers, and software-defined radios, as well as increased ease of collaboration and access to contract manufacturing are swinging things back the other way.
Think of it this way - a weekend's worth of dedicated cramming can get you a license that grants access to some rather large chunks of spectrum, often with relatively little in the way of restrictions on how you use it. That's the sort of resource that corporations spend millions for - look at the 700 MHz auctions going on now. That license gets you a huge radio frequency playground that's not only wide open for experimentation, it NEEDS active experimentation and exploitation or it will be taken away and auctioned off to the corporations. Don't wait for Google's Android to save wireless communications from the likes of AT&T - go develop an open replacement for a proprietary mode (start with Pactor III or D*Star's AMBE codec), or start a solar-powered 802.11b backbone, or SOMETHING.
Hell, just to make things interesting - I'll send one of my OpenTracker+ kits, free, anywhere in the world, to anyone with a Slashdot account that already exists as of today who gets a license before the end of February 2008. It may not be everyone's thing, but A) it's free and B) it comes with source code. Email scott@argentdata.com.
Funny how I've seen PSK-31 (a digital mode) work perfectly without a detectable (to my Field Day trained ear) signal. Morse may be better than voice... but a computer can outdo a human ear.
Note that I say this as a computer scientist and as a ham radio operator myself. I'm not suggesting that Morse is obsolete or useless... just that it's not automatically the best thing ever. The wonderful thing about this hobby is that it breeds innovation. From the earliest days of ultra-wide-bandwidth spark gap generators to a complete packet transceiver the size of an Altoids tin, the world of amateur radio, and the amateurs that have built it, is nothing short of amazing. However, if we really want to bring life back in this hobby, we need to stop all the infighting and think. We need to look at each operating mode honestly and attempt to appreciate the merits and the shortcomings of each of them. For every great thing you can name about the code, I can name another mode that does it better. But that's not what the hobby is about.
In response to the article, good on the Oregon hams, and congrats to them for getting recognized. They deserve it.
I'm waiting for a "-1 somepeoplejustshouldn'tgetmodprivileges" meta-moderation.
The code requirement for license to operate on radio bands that are considered long distance is mandatory by the treaties that setup a global radiospace for ham radio.
The code-free tech license is in bands that are for all intents (near Canada/mexico border would be the exception) are US only.
Any sufficiently advanced technology is indistinguishable from a rigged demo.
Morse is king if you want effective communication over long distances and have only low power available to you. If you have a computer then psk31 is probably (possibly) next best. Good software can pick up psk signals that are so quiet that they are below the noise floor. Ham radio experimenters are responsible for the early development of many communication technologies that we now take for granted. Don't write us off yet, there's still life in the hobby believe me.
So, it is kind of like Linux then?
