Amateur Radio

Amateur radio is a radio service in which people are allowed and encouraged to build their own radios, antennas, and so forth. It can be used to communicate all around the globe without any intervening infrastructure such as satellites or cables.

I am frequently asked, “Why bother with radios? Don’t you have cellphones? VOIP? Skype?”

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.

The TH-D72A is a very nice handheld Amateur Radio Transceiver. Among other things, it has an integrated GPS, built-in APRS functionality, full AX.25 Packet Radio TNC, and a USB port (which shows up as a serial device) to a computer – all built in.

Amateur Radio in Kansas

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.

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.

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.
