In search of the “perfect” antenna. A lot of off grid amateur radio involves compromises. We don’t have the same resources as grid-connected hams. Many off grid hams operate portable stations, which presents even more givebacks. One of the most common compromises is the antenna. When trying to go portable,… Read more »
Revisiting a classic. It’s been three years since I presented an article about the DIY portable DC power pack. It’s still one of the most popular articles here on Off Grid Ham. Almost every radio amateur has some version of this gizmo. Over the winter I had the itch to… Read more »
Where am I going with this? This article will be outside the mission of Off Grid Ham but I hope you’ll stay with me. I’m going to drift away from my usual schtick and use my substantial internet platform to bring attention to this neglected issue. My point can be… Read more »
That day will come. Those who depend on large storage batteries for their off grid needs dread the day they need to be replaced. It’s expensive, time consuming, and potentially dangerous. Common deep cycle flooded storage batteries bought at retailers will last about 2-3 years if used daily and maintained… Read more »
Over on the Off Grid Ham affiliate Google Groups.io forum a reader asked a question about how to properly maintain flooded batteries, also referred to as wet cell batteries. We have addressed this topic before but as a result of recent interest it’s a good time for a flooded batteries refresher course…. Read more »
I’ve been wanting to expand Off Grid Ham’s outreach for some time. I thought about starting an internet chat forum, but that would involve very disruptive changes to the website and a lot of ongoing maintenance. A Facebook page was considered too. I had more or less given up on… Read more »
It should not be this hard. Off Grid Ham reader Jim from Oregon, USA recently emailed to comment about the lack of on air radio nets specifically for preppers/survivalists and off grid hams. That sent me straight to my computer, where a cursory search suggested that he’s onto something. I… Read more »
Getting back to business. Since the holidays are over and we are in that dull time between New Year and warm weather, it would be a good moment to take stock of where you are with your off grid goals and determine where improvements are needed. If you got money… Read more »
A mature technology. AC inverters are like other technology in that during the early years they were very expensive and didn’t work particularly well. Over time they were tweaked and improved and today inverters are better and less expensive than their ancestors. I suggest including an inverter in your off… Read more »
In a recent article we did a deep dive into assembling a portable off grid radio station that was light and minimalist enough to be carried a fairly long distance by one person, but still had enough functionality to be an effective communications tool. That goal necessarily required using QRP… Read more »
A majority of off grid amateur radio involves portable operation with small systems. There are many reasons for this: Many people cannot afford large scale fixed solar; some are held back by homeowner association rules or want to incorporate amateur radio with camping & hiking activities. Other amateurs are motivated… Read more »
I always seem to find the coolest stuff when I’m looking for something else! While researching for a future Off Grid Ham article I happened across two on line propagation calculators that can determine what HF bands are best for any time or operating condition. There are many other similar… Read more »
