Maker Faire Bay Area 2015 T-Shirts for Makers
Maker Faire Bay Area is now history. Our booth, “Not Your Grandpa’s Ham Radio” included new projects and demonstrations. This was our fourth year as Makers and the fifth year as visitors to the Maker Faire in San Mateo.
This is a short overview of our display. Stay tuned for more images, stories and videos.
Here is the text from our handout. It answers some of our most-often asked questions:
What are we doing?
Thank you for your interest in our Maker Faire display “Not Your Grandpa’s Ham Radio.” This is our fourth consecutive year as “Makers,” and our goal is to show people what today’s ham radio operators are doing with the newest technology.
Who are we?
We are licensed Amateur radio operators (“hams”).
Is this like CB?
Yes and no. Ham radio is similar in that we use two-way radios and antennas to talk with each other, but hams can communicate using Morse code and computers in addition to voice, and we even have our own satellites. Ham radio requires a license issued by the Federal Communications Commission (FCC) in the US and licensees are required to pass a written test on electronics theory, radio regulations and operating procedures.
How far can you talk?
We can communicate with other ham stations around the corner or across the globe, depending on a variety of factors that affect the way radio waves travel. The equipment we are using operates on frequencies that generally follow line-of-sight paths. However, hams have discovered that signals can be reflected against objects such as buildings, trees, islands and mountains to extend the range. Using these techniques, we are able to contact other stations hundreds of miles away.
What kind of radios are you using?
We are builders and experimenters in microwave radio communications. No commercially-built, “off-the-shelf” equipment for these frequencies exists, so we must build our own equipment, or modify commercially-made equipment meant for other communications services, such as satellite TV, cell phone and long-distance telephone.
How much does this equipment cost?
Like any other hobby, people spend as much or as little as they can afford. Most people involved in ham radio spend as much as any serious stereo enthusiast, amateur photographer or woodworker.
