Communications Security (as good as it gets).

Beyond OPSEC. Last month we discussed operational security (OPSEC) and why it’s important to off grid hams. As a follow up to that, it’s worthwhile to talk about how to keep your communications private. After all, operational security is very difficult without also having some form of communications security. The… Read more »

Operational Security (OPSEC) For The Radio Amateur.

opsec

It seems so innocuous. Have you ever spotted an impressive antenna on someone’s house and thought, “wow, now there’s a kickass setup!” Or maybe you have a neighbor who goes for a one hour jog at the same time every day. What about that house up your street that is very… Read more »

You’re Invited to the Off Grid Ham Google Group.

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 »

Field Day 2018: Give Them A Reason To Care.

field day 2018

Field Day 2018 is almost here. It’s a contest, readiness drill, science fair, publicity stunt, geek festival, and party all rolled into one. It’s the Grand Poobah of amateur radio events. And this year my challenge to Off Grid Ham readers is not to fly solo. The task is simple:… Read more »

Hurricane Harvey Reality Check (some STILL won’t get the hint).

About a week in, the epic story of hurricane Harvey is still unfolding. Compelling video footage of human decency and nature’s violent fury are at the same time both uplifting and disturbing. No matter what else happens and no matter how devastating the damage, I am confidant that the American… Read more »

Alpha-Delta DX-EE Antenna: Product Discussion

      4 Comments on Alpha-Delta DX-EE Antenna: Product Discussion

I am usually against buying wire antennas, especially dipoles. It seems kind of lazy to buy something that can be made quickly for very little money. There are exceptions, though. In my situation, I needed a multi band antenna for limited space and would work without a lot of tinkering… Read more »

Go Beyond The Ham Bands…It’s Scanner Time!

scanner

Radio amateurs who never drift outside the ham bands and don’t see a need for a scanner receiver to monitor other services are cheating themselves out of a very valuable resource. Not only is monitoring non-ham communications interesting and fun, it can give you a huge advantage in a shit-hits-the-fan… Read more »

Field Day 2016: Activate Off Grid Systems!

A recurring theme at Off Grid Ham is the importance of going out and testing your ideas and projects in real world operating conditions. Very few of my schemes have ever worked exactly as planned the first time I tried them. Most needed modifications; a few were complete flops and… Read more »

DIY: The Off Grid Ham Portable DC Power Pack.

There are not too many options for radio amateurs who want portable DC power beyond the batteries in their devices. The Off Grid Ham 100 Watts For $300 Solar Power Plant is one alternative, but that can be too much for the ham who only needs to run a handheld/QRP… Read more »

Go Box Zen: Know Where You’re Headed Before You Leave.

go box

Go boxes are a well worn subject in ham radio circles. On prepper/survival internet forums in particular, the topic has been beaten beyond death. In nearly all of these discussions, there is a lot talk about the how, but not much on the why. When reasons are given, they are… Read more »

NVIS -Near Vertical Incidence Skywave: Why You Need It.

One of the big thrills of amateur radio is working DX. There’s a lot of excitement in contacting that “Holy Grail” station on the other side of the world and earning bragging rights on local FM repeaters. But crisis communications necessitate that amateur radio operators trade DX glory for close… Read more »
