Ham Radio Still Growing In the iStuff Age
vhfer writes "From NPR comes this story about old-school communications in the age of Twitter: 'Only a few years ago, blogs listed ham radio alongside 35 mm film and VHS tape as technologies slated to disappear. They were wrong. Nearly 700,000 Americans have ham radio licenses — up 60 percent from 1981, a generation ago. And the number is growing.' The article goes on to say that while there's plenty of 60-plus year old hams, there's also a growing contingent of teens. I just met a 14-year-old, licensed in 2009. Getting rid of the Morse Code requirement sure helped in that regard. So does the fact that the test questions (and the answers) are freely available, legally, on the Internet. Study, take the test, hang the license certificate on the wall. Your geek cred gets an immediate boost. And who knows? Maybe the next time there's a Haiti-earthquake-sized disaster, you'll be one of the thousands of ham volunteers who provided the only communications in/out of Haiti for weeks following the quake, not to mention all of the tactical comms the country had for nearly a month."
Here in Nebraska just last week we had a need for Ham radios when our telephones went dead. No problem for cell phone users until they tried to dial 911. Out came the Ham radio operators using the contingency plans for y2K parked at major intersections where people could get a hold of them and contact authorities. There are just some technologies that are just too useful to get rid of.
CS: It is all sink or swim...oh and did I mention there are sharks in that water?
I'm not sure you're actually correct that thousands of hams provided the only communications out of Haiti after the earthquake and all fo the tactical coms. While there were a few messages coming out of Haiti over amateur radio there wasn't much. Cell phones were brought back up pretty quickly and a friend of mine who was in Haiti doing relief work after the quake (Specifically as a comms officer for a relief org) said that he had very little use for HF as satellite connections were brought up pretty quickly. He did say there was some use of VHF to establish local communications between relief orgs and various med stations etc but that other communications came up quickly enough that amateur radio didn't play as big of a role as many would like us to believe. If you want a great technical hobby where there's a lot to learn and an opportunity to make friends all over the world become a ham. You might get an opportunity to help out in a disaster, but if your main goal is to help out in emergencies, get trained in CPR, Search and Rescue and other such, but don't count on being a ham to put you in the "Most needed" category. There is a place for amateur radio in disaster relief, but it's as a backup, not a primary communications method. The fact is the pros can do a better job than we can.
Talk with people around the world by bouncing signals off the moon
On "HF" or shortwave radio, you can talk to people around the world with 100watts of RF power. 100w is probably 1/3 or less of the power used to run your desktop computer.
It's probably one of the geekiest of the geek hobbies. You can play with electronics and build and repair radios. You can interface radios with computers and send and receive messages over radio. You can play with RF and antenna theory, flexing those math muscles to enhance your signal.
You get to talk without infrastructure
Cool people from around the world to talk with, and you never know who you're going to talk to next. Kind of like fishing
And, unlike chatroulette, very few of them are masturbating.
I've abandoned my search for truth; now I'm just looking for some useful delusions.
I remember when I got my license when I was about 14-15 and was damn proud to get it. I had learned morse code in the Boy Scouts so that test was fairly easy. I remember going to "Ham Fests" where you could buy any sort of electronic gizmo, whether for your ham radio, a box of floppies, home grown software, etc. I even bought a fairly powerful FM transmitter. Taking the morse code out of it takes away the learning and the challenge, and also the feeling of accomplishment.
The Revolution Will Not Be Televised
Are you adequate?
Well, in addition to the simple chatting thing and the gee-whiz hobbyist angle, it can be an extremely valuable resource in emergency response scenarios. Many areas have volunteer emergency networks comprised of ham radio operators that could relay information and coordinate response efforts if the official response groups are overwhelmed or disorganized.
The draw depends upon the person. Many hams are drawn to the hobby by building their own equipment and/or antennas. There's a lot of math and theory that goes into building transmitters and creating good antenna designs. Not to mention, the pride of breaking through a pile of amateurs wanting to talk to someone in a foreign country and mentioning that you are using only 100 watts into your antenna that is a "homebrew 7 element beam at 50 feet".
Some modes in amateur radio require above average skills that the test doesn't cover; things like moonbounce, long distance microwave or satellites (hams have their own low-earth orbit satellites).
There's also the computer aspect of it. Hams have developed their own digital modes that use very low power and require DSP techniques to use, as well as software defined radios.
The hobby has a lot of interesting facets other than just talking to your friends on the radio. These are what keeps it going in an age when it's easier to just fire up Yahoo IM or use a cell phone.
Why ham radio?
I'm back into Ham Radio after a 20 year lapse.
I got my license back when you had to travel to an FCC office for the test and pass a 5, 13, or 20 word per minute listening test for morse-code.
It is a great nerd hobby, especially if you get into the do-it-yourself aspect, digital modes, or especially software defined radio.
I can buy a SoftRock kit (google it) for less than $15 that does the initial downconversion and lets me use my soundcard+computer to visualize a large chunk of a single band, decode CW (morse), various digital modes and SSB voice.
WSPR mode allows you to put your computer to work sending and decoding ultra low power (milliwatts) + ultra low bandwidth (seconds per bit) to communicate around the world on battery power.
Ham Radio definitely took a hit from the internet and cellphones providing cheap and easy worldwide communications. Removing the morse code proficiency requirement and volunteer examimations has helped bring it back somewhat (I never minded the morse part, but it was a stumbling block for some who where in all other respects a perfect fit for the hobby).
If I was just interested in communicationI probably would not have come back to the hobby, but the nerd part is just too fun.
I'm currently using a cheap Direct Digital Synthesis chip (google DDS) interfaced with an Atmel microcontroller (google Arduino) as the basis of a do-it-yourself low power transceiver for digital modes.
Nerd heaven...

...that you know of.
Sometimes you also get fun stuff like what's coming up in a week. The Arecibo radio astronomy antenna (huge white dish) is bouncing signals off the moon and listening for ham radio operators in a week or two
Granted, it takes a fairly big antenna and lots of power to bounce signals off the moon. However, there are computer programs that allow for slow text transmission (think really slow modem) via moonbounce, reducing the antenna and power requirements.
An amateur radio license is a license to make use of large swaths of radio spectrum set aside just for hams. There are many things that you can do within that spectrum, including experimentation of new ways of using spectrum that others haven't tried yet.
Most obviously, you can talk to people using your voice and a microphone.
Or you can talk to them with a number of digital modes, with morse code being one of the most widely known examples, but other computer-based digital modes also enjoying much popularity.
You can study theory on RF propagation on different parts of the radio spectrum using beacons.
You can transmit a TV signal from a model rocket.
You can install an APRS beacon in your car and use it like a LoJack if your car is ever stolen.
You can fly a radio controlled airplane really really far because your transmitter can legally greatly exceed the range of the stuff most non-licensed people get to play with.
You can fly a weather balloon and transmit photographs and telemetry back to you.
You can work on improving Search And Rescue communications capabilities.
You can provide direct vital assistance in the aftermath of a natural disaster by coordinating radio communication between government agencies and NGO's in ways that none of them have the internal capabilities to handle.
You can play some really cool uber geeky games like "fox hunting" where you put your radio direction finding skills to the test. If you like geocaching, you'll get a real kick out of this.
You can send data over vast distances wirelessly using more powerful transmitters than the unlicensed public on spectrum that is reserved for your use as a licensed amateur radio operator.
This can just keep going. You can push the envelope, developing new technologies, or you can master antiquated skills on vintage equipment. Or you can just jabberjaw on the drive to work with other hams. Whatever floats your boat.
My 4x4 group (hot4x4.ca) uses VHF almost exclusively due to its reach above and beyond CB. Cell phones usually don't work where we travel either. Depending on the terrain, we can reach over 75kms from each other on just the 2m band w/o a repeater. This only requires a technician (basic) license as well.
Add in the APRS + Garmin GPS, and your rig turns into a mobile GPS transmitter. We then can track each other, which makes it really easy to find each other. APRS also allows us to send text messages via a p2p network of Ham Radios. Example: we had guys in Reno who we needed to contact because we broke a part on the Rubicon. Couldn't reach them via radio, but with APRS, our txt msgs could be relayed.
None of this requires anything but the first class license. Its an awesome hobby and there is a lot you can do with it, in addition to Geek cred and ecomm or search/rescue.
I was asleep (off watch) at night on a small sailing yacht crossing the North Sea. The guy on watch woke me and asked what it means when a ship flashes a light three times. After asking him a few sleepy questions I figured out that the ship was flashing dot-dot-dash with a signaling lamp, the Morse letter "U" which, at sea, means "you are proceeding into danger". After going on deck and confirming that, I helped him tack the yacht and avoid passing between the ship and the oil drilling platform that it was towing. Morse is still used on HF and with Aldis lamps as a backup when more modern modes fail.
Isn't it ironic that Ham Radio is meant to be a communications system for amateurs?
Up until the 80s, ham radio was about doing something that there was no other way to do. Talk to people around the world "for free", without depending on any one else (like the phone company) to make it possible. It really was a magical thing.
But then the internet came along and ham radio started to die because the internet completely replaced a major part of what made ham radio cool. And so for the last 20 years or so ham radio has been in a sort of limbo and decline due to the rise of computers and the internet.
But now we're entering a new era, one where "well, duh, of course I could just twitter to people around the world, but communicating via radio is actually more fun". It's now interesting because it's sort of an antique rather than in spite of it.
There's a progression where things go from "valuable" to "junk" to "collectible". The trick is to avoid throwing them away during the "junk" phase, because eventually they get old enough that they become interesting again.

Not really, no. Your Ham Radio license is granted with the understanding that you will not conduct business on it. You cannot, for example, get on 2 meters and say "anybody wanna buy my telescope? $50!"

This pretty much requires Morse Code, but if you can key out enough to tell people you just picked this up and are learning code on the fly, you will get postcards from all over the world from people who also communicated with you using barely enough power to give you a mild tingle. Morse Code is essential because you can make out chirps and tones from the static, where voice would just be a waste of time. The way the FCC is letting things go, I would not be surprised if they let you use a keyboard and forget paddling entirely.
Hey, simple codes were good enough for Pioneer, Mariner, etc. That's geek cred - talking around the world with less power than you would need to read the postcard with...
I got my First Class for a job fixing CB radios, and got hooked a little bit back when code was required. I hated code. Helped a college FM station stay on the air for a little while. Being able to solder well got me into several circles, and I was building Heathkit rigs for people for a little while, cause they liked the perfect joints and wire ties I learned in the Air Force, when whire ties were waxed cord. I still think they are pretty, and I did a cabling job with about 200 drops once all in flat nylon lace, just to show the guys how nice exposed cabling could look. But that was then. Now there are so many great kits out there, Amazing. I really ought to get back into it. Oh yeah, I let my ticket lapse when I got sidetracked by soccer and girls. Feh.
deleting the extra space after periods so i can stay relevant, yeah.
