Off Grid Ham: Go Boxes

Dan Passaro’s shack in a can.

In this article, Chris Warren of Off Grid Ham spends a little bit of time talking about ham radio go boxes. For ham radio enthusiasts, the radio go box is mostly commonly used when responding as an emergency communications volunteer or for fun, portable radio communications while camping or hiking. But the go box holds a place for preppers, too, even if you aren’t an amateur radio licensee. Even if your plan for emergencies is to “bug in” (stay put at home) there are disasters which may force you out of your home, and you will want some kind of portable communications ready to go – whether that is ham radio, FRS, GMRS, MURS, CB or just a kit for keeping your cell phone charged up.

Go Box Zen 2.0

I didn’t realize it’s been over three years since the last time Off Grid Ham specifically addressed go boxes. If the internet discussions and on air chatter are any indicator, it’s a very popular way to operate. It’s way past time to revisit the humble ham radio go box and come up with some fresh ideas.

In the last three years I’ve noticed an uptick in ham radio go box deployment. There are even entire social media pages dedicated solely to go boxes (or bags or whatever your thing is). I think there are several reasons why. Many operators live under homeowners’ association rules that severely limit having a fixed antenna. Theses operators may have no choice but to hit the road. Others want something they can take camping, for SHTF purposes, or EMCOMM. The various special event stations from parks and other significant places may be driving the trend too. There’s also new equipment manufacturers offering low cost gear. This opened possibilities to people who could not otherwise afford a dedicated go box.

As before, this is not going to be a step-by-step how to on building a ham radio go box. There are too many variables and too many individual choices for me to come up with a plan that works for everyone. Instead, we’ll go over some concepts to consider and questions you’ll need to answer before you begin.

Defining priorities.

What is the Number One priority for your ham radio go box? It it portability? DX-capability? Data modes? Keeping the cost down? Before you can construct a go box, you have to decide what trait is the most important. From there you can work in secondary needs. As with everything, there will be compromises, and some things are mutually exclusive.

The main reason ham radio go boxes do not live up to expectations is because they were not built to expectations in the first place. Or possibly, what you thought was a Number One priority turned out to be not such an urgent issue after all. Years ago my first go box was a huge fail because my Number One priority, cost savings, meant giving up so many other smaller things that they made the cost savings not worth it.

The main parts of my new & improved, much lighter ham radio go box. Left is a 27 watt folding solar panel. Top is a DC power box which includes a 13 amp-hour lithium battery and the charge controller. Right is a random wire antenna. Not shown: Alpha Antenna FMJ.

I used an old Yaesu FT-757 GX II radio. I also dug up an inverter, a solar controller, an FT-2900 2-meter radio, a 100 watt solar panel, and some various plugs and connectors. All of this stuff I already had. I built a nice wood box to mount everything in. My out of pocket cost for the entire project was less than $100.00, and most of that was for a 35 amp hour SLA battery. It looked impressive. I felt like a boss!

Well guess what? I achieved my goal of keeping the cost down, but my ham radio go box was so clunky and heavy that I didn’t care. Between the battery, the wood box, and all the other stuff, I could barely move that beast by myself. There wasn’t much “go” in that go box, unless I invested in a forklift too. I thought saving money was my Number One priority but I gave up too many other attributes to make it worthwhile.

That was my lesson in not only defining priorities, but also considering what else I have to give up to attain that priority. I inadvertently buried the cost savings under all the other problems. I used that go box only once or twice, then dismantled it.

What comes next?

After admitting defeat in my first attempt at a ham radio go box, I reexamined my priorities…
