Most of us carry cell phones with us almost everywhere we go. So much so that we often forget not just the usefulness, but even the joy, of having our own radios. For instance:

The Family Radio Service (FRS) and General Mobile Radio Service (GMRS) are both radio services available to the public in the United States and other countries.

When things are difficult – maybe there’s been a disaster, or an invasion (this page is being written in 2022 just after Russia invaded Ukraine), or maybe you’re just backpacking off the grid – there are tools that can help you keep in touch, or move your data around. This page aims to survey some of them, roughly in order from easiest to more complex.

For a number of years, this was a public wiki, but due to high volumes of spam, it hadn’t been editable for a number of years. In February 2022, the content from that site was folded into this one.

Amateur Radio really a very interesting hobby. It is the most versatile radio service available in many ways. Users of amateur radio get to choose their own radios and antennas, and can even design and build these things themselves if they like. They can operate with a surprising amount of power in many situations, and can work with all sorts of modes including CW (morse code), voice, and digital. Most other types of radio restrict people to only government-approved radios, certain specific channels, etc.

So, you may have read the material on the Why Get Involved With Amateur Radio? and are wondering how to get started. This has two main components: licensing and equipment.

I am a programmer, manager, hobbyist, advocate, volunteer, dad, and nature lover. I live out on an old farmstead in rural Kansas that once belonged to my grandparents. The nearest paved road is about 3 miles away, and the nearest town (population 600) is 7 miles away. I have three incredible children, which I might occasionally mention on my blog.
