![]() ![]() This spectrum has been sliced up by the FCC to reserve specific bands of frequencies for specific radio technologies. There’s a lot of devices that all have to share space in the radio frequency spectrum. You can break electromagnetic radiation down into a spectrum as shown below, which is categorized in order of decreasing wavelength and increasing frequency to include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. This electromagnetic radiation travels in the form of a sinusoidal wave, and the particular wavelength and frequency of the wave will determine what kind of electromagnetic signal you’re working with. Like other wireless technologies, ham radio uses the power of electromagnetic radiation to send voices, Morse code, and digital data around the world with the help of transmitters, receivers, and antennas. So whether you want to dive deep into wireless communications, build up your electronics theory, or experiment with digital signaling, there’s something for every maker in a ham radio hobby. At its core though, ham radio enthusiasts are all known for their nature of being tinkerers and inventors. Of course, this list is by no means exhaustive and the uses for ham radio are only limited by your imagination. With some newer transmission technologies you can also send digital signal around the world to share things like pictures, without ever needing wireless internet.īounce a radio signal up and off the moon for even greater distance. Ham radios aren’t just for voice communications. Don’t be surprised to get a postcard back when you make a contact, this can make for a great collection throughout the years. Other ham operators will take part in contests to see how many hams they can connect with in distant locations. Some ham radio operators get their kicks by bouncing radio waves off of the moon communicate with others around the world. As if bouncing radio waves off of our ionosphere to lengthen the distance of our communications isn’t enough. Outside of space adventures and emergency situations, you’ll also find ham radio being used for: And by holding the radio to the window, which positions its antenna in the line of sight with other radios down on earth, a lone man flying through space can chat with those of us on the ground with this amazing simple technology. An astronaut traveling on board will typically bring a 1-5 watt handheld ham radio with them. Take for example the International Space Station (ISS). The uses for ham radio extend far beyond emergency situations though. Ham radio is doing what it does best in times of crisis. This wireless technology is relied on as the sole method of communications during emergency situations, and you’ll find volunteer-based emergency groups that offer their ham radio expertise to coordinate aid and relief assistance for those in their community. During times of crisis, when our fragile cellular networks and power grids limp along, ham radio keeps on running. You likely know about ham radio for one of its most vital uses, serving as a reliable communication system when disaster strikes. And once you’re fully equipped with the needed equipment, the world is yours to communicate and connect. The Basics of Ham Radioįor those interested in wireless technology and tinkering, ham radio provides a solid introduction to basic electronics theory and radio communications knowledge. What will it be about for you? Perhaps a great opportunity to learn about basic electronics? Let’s find out. ![]() For these kids, ham radio was the equivalent of today’s smartphones or wireless internet, and allowed them to communicate with others around the world with no wires in between! For Dustin, Mike, and Lucas, ham radio was like a gateway into an invisible dimension, and an alien one, allowing them to connect wirelessly with some simple electronic components. In one scene, three boys are sitting around their very first ham radio with their science teacher in tow. ![]() It also features some excellent electronics technology that was at its prime back in the 80s and is still kicking today. 10 min read Hamtastic: A Beginners Guide to Ham Radio, and How to Make Your Own In Autodesk EAGLEĮver watch the Stranger Things series on Netflix ? It’s not just a great show with Stephen King-like paranormal activity wrapped up in an idealistic 80s town. ![]()
