My Adventures In Amateur RadioI am an amateur radio enthusiast. Amateur radio, or 'ham' radio, has been around as long as radio itself. The hobby has dozens of different facets, from simple chit-chatting on the air, to DX (long distance), to Foxhunting (direction finding), to ARES (emergency service), to Sattelites, to Microwaves, to SSTV (slow scan television), to experimentation. There are so many different aspects to the hobby that it'd take a lifetime to be involved in all of them. In Canada, amateur radio is regulated by Industry Canada, who issue the licenses. My station license (call-sign) is VA3UXB. I also have VA3GRR, which is my automatic radio beacon, and VA3XXX which I plan to use for experimentation and possibly building a 900 MHz repeater in the future. I have been a 'ham' since the autumn of 1996, when I joined the Peel Amateur Radio Club. Through PARC, I have gotten my Basic and Advanced qualifications, and my 12 words per minute Morse Code endorsement. I have been a member since I became a ham, and have also served two years on the club's board of directors. My interests in amateur radio at the moment lie in three distinct areas: Community Service through the ARES group; technical aspects such as homebrewing and kit-building; and Foxhunting, as described below.
Kit Building & HomebrewingOne of my favorite passtimes is building things, and ham radio has lots of opportunities for building stuff. From true homebrewing, i.e. designing and building gear from scratch, to buying and assembling kits, from 'accessories' like antenna tuners and SWR bridges, to complete transcievers, to computer interfaces, there are lots of ways for hams to 'roll their own' gear. Kits are a great way to get started in homebrewing. Kit building can be very educational, and give a lot of satisfaction when complete, while being relatively 'safe' in the sense that the design is (typically) already tested and proven. Lots of great companies sell kits. One of my favorites is Elecraft, based in California. I've built two of their transceivers, the K1 and the K2. Although kits are a good way to get started, not all kits are created equally. The best one use proper printed circuit boards, and include everything needed to bring the project to completion, including a proper enclosure. Some include just a circuit board and parts, and some include just the circuit board and schematics. One of the best things about kit-building or homebrewing, is that if something should go wrong with the gear later, you're usually able to handle the repair yourself -- after all you built it! Plus, if you want to make changes, or you want to modify it or adapt it in some way, you already know all the inner workings, making it much simpler to get in there and tinker. Another great way to get started in homebrewing, is through your local radio club. The Peel Amateur Radio Club for example, has regular Project or Homebrew Days. FoxHuntingAnother passion of mine is Foxhunting! The technical term is Radio Direction Finding... Typically what we do, is one person will hide somewhere in our city with their radio. They will transmit every now and then, like every 5 or 10 minutes. Everyone else has to try and find them, by homing in on the transmissions. Foxhunting can get complicated, using various kinds of antennas, attenuators, radios, GPS and mapping software, and even a computer. Or it can be as simple as one person, one radio, one directional antenna, some 'eyeballing' and guesswork. Perhaps surprisingly, I find the second method is a lot more effective. The more gear you have and the more complicated it gets, it seems the more likely it is that something's going to be off kilter or misaligned.
Peel Amateur Radio Emergency ServiceI'm also an active member of our local Amateur Radio Emergency Service. ARES exists to provide experienced communications services in times of emergency. We hold regular meetings and training excercises, in order to keep as prepared as possible. We have several activities throughout the year, and have been called on to assist with various emergency situations:
CANWARNCanwarn is a 'joining of forces' between amateur radio enthusiasts and Environment Canada. In Ontario, we average about 20 tornados every year. The 'tornado season' usually runs from April until September. Many people may think that with the advent of 'dopler radar' and other new technologies, that there will be lots of warning before a tornado forms. In fact, the resolution of a radar image is measured in kilometers, while the average tornado is only 50 meters across. Radar can tell a professional forecaster that a storm is capable of spawning a tornado, and forecasters use their judgement to determine if a tornado is likely. However, only a trained pair of eyes looking at the sky can tell if a tornado is in the process of forming. Anyone can identify a tornado that is on the ground. By that time, it may be too late for the community it may have touched down in. This is why it is so vital to have trained weather spotters out there, and a way to instantly get the message of what they see back to the professionals. A trained observer reporting that they see a tail cloud, or a wall cloud in the process of forming, may allow the Severe Weather Office to issue Tornado Warnings with enough time for people to get to safety. Canwarn spotters are the eyes for the Severe Weather Office. This is the job that over 1500 volunteers across Ontario are doing. Contributing their time, expertise and equipment, these Canwarn-trained radio amateurs provide an important service to the communities of Ontario. When severe weather threatens, volunteers in the affected areas tune their radios to their local 'Net' frequencies, and check in to the communications Net. In charge of the Net is a Controller (usually operating from a 'radio room' in Environment Canada's Toronto offices) who takes weather reports from the radio amateurs, and passes these reports directly to the Severe Weather forecaster. From the radio-room at Environment Canada, a Net Controller can communicate with Canwarn spotters across the province, or even across the country, should there be a need for national emergency communications. |
