Both sides now. Anyone who experienced even modest exposure to amateur radio has probably seen many articles and videos about how to get started, what equipment to buy, reading material, etc. Whether or not this advice is good is outside our purpose here. I recently noticed that of all the… Read more »
We have no home of our own. The ham radio world has plenty of contests and events. Unfortunately, almost none of them are directly relevant to off grid and QRP operators. Field Day comes to mind first, yet it is hard for anyone but the biggest high-watt boomer stations to… Read more »
They are everywhere. If you haven’t already incorporated a gas powered generator into your off grid ham radio plans, you’re excluding a valuable resource. In the last decade or so, the variety and availability of generators has increased exponentially. Along with greater market penetration comes conflicting information and misunderstandings. Knowing… Read more »
Filling in the gap. Most ham radio enthusiasts who focus on off grid operations spend a lot of time working with solar panels, batteries, generators, and similar equipment with the end goal of having a fixed-or semi-fixed base station. Whether that station is a permanent installation, such as in a… Read more »
Been there, done that. Back in February 2020 we first discussed perovskite solar here on Off Grid Ham, and then again in July 2023. What has happened since then? At first glance the latest news seems frustrating and stagnant. The chatter continues but several years on we still have no… Read more »
The best of times. Battery technology has made huge advances in a relatively short amount of time. When batteries started being commercially produced in the early 1900s, lead acid or “wet cell” batteries were the only option. “Dry cell” batteries were made too, but they were for small applications such… Read more »
A classic never goes out of style. Way back in 2016 I posted the Off Grid Ham 100 Watts for $300 Solar Plant. Even today, that article is still hugely popular and one of the most viewed posts on this website. In a 2020 update, the $300 threshold not only… Read more »
Exponential market growth! Lithium battery technology has made exponential market penetration in the last decade or so. Once an exotic and expensive platform, today nearly every battery-powered device uses lithium. Along with increased market acceptance comes attention, both good and bad. Most of the bad news circulating about lithium batteries… Read more »
It’s better to have it and not need it, than need it and not have it. It’s been quite a summer! Flooding, extreme heat, wild fires, and (at this writing) a hurricane just tore up the Western USA and another storm is churning in the Gulf of Mexico. Every time… Read more »
The “holy grail” of solar energy? It’s been over six years since Off Grid Ham first covered perovskite solar. For the unfamiliar, perovskite solar is a new type of photovoltaic technology that is based on perovskite-structure crystals. There are several advantages. First, is efficiency. Perovskite solar is far more efficient… Read more »
Wish list. Most off grid hams are off grid only for portable operations. Many of them would like a larger, permanent home system but don’t know where to start or what such a project involves. If having an off grid home solar power system has been a longtime wish, this… Read more »
Graduation time. A lot of if not most off grid hams have only one battery in their system. Connecting a single battery is more or less self-explanatory. What should you do when you expand your system to include multiple batteries? Should they be in series? In parallel? Is one way… Read more »
