I was on the brink of pulling the trigger on the purchase of a new automatic antenna tuner for my portable rig recently, when something unexpected happened that slammed the brakes on the acquisition.

How Does a Ground Tuning Unit Work?
I have spent many hours in my reclining thinking chair, posting ideas on the back of my eyelids while contemplating this very question. How indeed does a Ground Tuning Unit (GTU, aka Artificial Ground) actually work? I have a fairly reasonable comprehension of the theory behind antenna tuners, but tuning an entire planet?

Ham Radio? What’s that?
Now we have moved into the summer season I have been getting quite a few folks stopping by while I am operating in a public park.

There are a lot of YouTube videos showing different ways to support a fiberglass antenna pole, none of which seemed to meet my needs which are fairly basic: rapid deployment, lightweight and uncomplicated.

Ham Radio & the Art of Bushcraft
Operating a radio in the great outdoors can be as simple as parking your vehicle, pulling a radio out of your pack, attaching an antenna to the top of the driver's window and keying up.

How to Use a Semi-Automatic Antenna Tuner
There are manual antenna tuners and there are automatic antenna tuners - but what is a semi-automatic antenna tuner? I'll explain in a moment, but first a bit of background.
