The RaDAR Is Perfect For Us.

      2 Comments on The RaDAR Is Perfect For Us.
RaDAR

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 »

Conventional and Inverter Generators

      8 Comments on Conventional and Inverter Generators
generators

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 »

Wishing the best to everyone. Fortunately, the worst of hurricanes Helene and Milton are in the past. The effected communities have had time to evaluate the damage and hopefully found reasons to be grateful. For the rest of us, we can assist as needed, pray for their recovery, and do… Read more »

NVIS for EMCOMM and Survival Communications.

NVIS

Not clear on the concept. If you or someone you know has an HF station with a goal of DX communications in disaster situations, I have a question: What are you really trying to do? What is the need for very long distance communications in a SHTF scenario? Save for… Read more »

What is Your Off Grid “Plan B”? Do You Even HAVE a Plan B?

When the Sun lets you down. Loyal OGH reader Randy from Wisconsin recently commented that for several weeks in June and into July he barely got anything at all out of his well planned, high-budget home solar power system due to nearly constant clouds and rain. His dilemma highlights a… Read more »

Data Modes: Game Changer or Gimmick?

      2 Comments on Data Modes: Game Changer or Gimmick?

Time + technology= options. Ham radio has a lot more options than it did years ago. Back in the day your choices were phone or CW and that was about it. In the 1970s/1980s slow scan TV and early data such as RTTY came about, but they were niche modes… Read more »

Wind Turbines For Off Grid Radio: Pros and Cons.

wind energy

The unloved child. Lots of hams are very successful with solar. It seems to be the “go to” off grid power source. I don’t have firm numbers, but anecdotally it appears solar is more popular than even gas generators. Of course, solar is not the only game in town. Wind… Read more »

Turn Thinking Into Doing (But Do Some Actual Thinking First).

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 »

Batteries: Your Weakest Link.

      18 Comments on Batteries: Your Weakest Link.
batteries

It cannot be avoided… Batteries are arguably the weakest link in the off grid radio chain. Solar panels, controllers, connecting cables, and almost everything else can last years, even decades. But batteries are a consumable product and no matter how good yours are, it’s almost certain they will not last… Read more »

Cheap & Easy Portable Antenna Hacks!

      9 Comments on Cheap & Easy Portable Antenna Hacks!

Revisiting an old topic. I don’t do a lot of antenna articles because there is already so much information in circulation I can’t see much ground left to cover, at least that’s what I thought until new Off Grid Ham reader Rick sent a nice email that inspired this article…. Read more »

Portable Antennas For The Off Grid Ham.

We’re not special. Off grid amateurs spend a lot of time focusing on the power source for their equipment. While that’s understandable, we musn’t be distracted from the rest of the amateur radio chain. This time we’re going to look at the other end of the system: portable antennas. To… Read more »

Add a DC Power Monitor To Your Off Grid System.

More than just bling. Charging, discharging, watts in, watts out, current, voltage, and other values can tell you what your off grid system is doing. Having data helps you plan your power usage and forecast problems before being caught short. A DC power monitor addresses all these issues and is… Read more »
