The Transmitters of Freedom, Chapter 3: COMMENTARY.

shortwave

A moral imperative. On two previous occasions (here and here) this blog published editorials calling for a shortwave radio broadcast “revival” to oppressed foreign countries with censored internet and no free speech protections. Since then, shortwave broadcasts have declined even more. The invasion of Ukraine by Russia and other world… Read more »

Battery envy. I recently received a very nice email from Mike in Missouri where he described converting his home off grid system to lithium batteries, at a cost of over $7000.00 USD! My own home system is still on old school flooded batteries because I have not recached a point… Read more »

The frog in the soup pot. I believe the average Off Grid Ham reader has above-average intelligence. They also have a good grasp of what’s going on in the world. While this blog does not often delve into amateur radio politics (and even then we tread lightly), every now and… Read more »

WINTER HAM RADIO

Are you hibernating this winter? Where I live, and for most of you, it’s really cold! It seems like after the Christmas season is over no one is motivated to do much winter ham radio. It is a great time to keep going with radio activities. Of course, we need… Read more »

When you want it now. off grid ham quick start I recently received an email from a reader who suggested that I write an article about how a newcomer to off grid radio can get started: Batteries, solar panels, etc. I was like, wait…whaaaat? Off Grid Ham is not a… Read more »

They’re all (mostly) the same…on the outside. Solar panel technology has gotten so inexpensive that even the tightest budgets can do it. The solar panels on my roof cost about $2.50/watt ten years ago. Today I could replace every one of them for less than half that. In some cases… Read more »

Guilt trip. I came across an interesting discussion on an internet ham radio forum. The author, a ham, had misgivings because after being hounded (his term, not mine) to join an local emergency communications (EMCOMM) group, he finally had enough of the nagging and told them to shove it. Afterward… Read more »

Greater than the sum of its parts. Along the summer I’ve collected bits and pieces of topic suggestions and ham radio news. Any one of them by itself is not worthwhile as an entire stand-alone Off Grid Ham article, and a few are not even directly ham radio-related. But collectively… Read more »

It’s been a while. It’s been quite a while since I did an inverter article. Inverters have not changed a lot since then, but there’s still some new material to go over. It’s also a good opportunity to review older concepts. Most hams know what inverters do but don’t know… Read more »

Getting Out of the RFI Maze

RFI

One of the hardest problems to understand. Amateur radio is full of difficult challenges, but few of them approach the hair-pulling level of radio frequency interference, or RFI. It’s a hard issue to address because there are so many variables. For example, sometimes moving a piece of equipment just a… Read more »
