Many years ago I learned about a design technique called KISS. It was an acronym for "Keep It Sweet and Simple". Somewhere along life's journey I started seeing the acronym change to the rather offensive "Keep It Simple Stupid" which I entirely dislike. There are many sound reasons for simplifying a design but none of … Continue reading I KISSed my Antenna – Here’s Why …

25 Years a Ham and Still Learning
I actually got my "ticket" a little late in life. I spent many years as an SWL, then college, career and a family took priority. By the time my wife and I became empty-nesters I had combined my passion for radio and Space "the final frontier" by chasing satellites; military satellites mainly. I formed the … Continue reading 25 Years a Ham and Still Learning
An End-Fed Half Wave Antenna – with no impedance transformer?
One of the great benefits of being a ham radio blogger is that it opens up a new door to learning. Through that door comes valuable input from readers of Ham Radio Outside the Box. Let me state one thing very clearly: I am not an expert; the intent of this blog is to report … Continue reading An End-Fed Half Wave Antenna – with no impedance transformer?
A Quick and Easy QRP Emergency Field Antenna
I once drove to a park about 45 minutes away from home to do a POTA activation then realized I had left my antenna at home. <<Panic>>. I improvised by digging a 33ft wire out of my pack, cutting it in half and hastily erecting a V-dipole with its ends only about 10ft above the … Continue reading A Quick and Easy QRP Emergency Field Antenna
How to Really Make the QMX Ready for the Big Blue Sky Shack
The QRP Labs QMX is a wonder of modern technology. By employing an SDR hardware platform a whole plethora of features can be made available by simply installing new firmware. I absolutely love my QMX. It has become my most used radio for field operations. I grumbled into my beer glass about the long wait … Continue reading How to Really Make the QMX Ready for the Big Blue Sky Shack
An Off-Center Fed Sleeve Dipole
At Ham Radio Outside the Box the urge to experiment is always front and center. Isn't that what radio amateurs are supposed to do - continuously improve our knowledge and hone our expertise? In the minds of the government departments that give us our spectrum allocations we are a reserve resource of communications expertise to … Continue reading An Off-Center Fed Sleeve Dipole
A Top Loaded End-Fed Half-Wave Antenna for 20m
Imagine this: a short, vertical antenna for 20m that requires no ground, no counterpoise or radials ... And ... no tuner. Now, let's add that it is only 14 feet tall and can be erected in just a couple of minutes. But wait, there's more: it is very lightweight, slips into a shirt pocket and … Continue reading A Top Loaded End-Fed Half-Wave Antenna for 20m
CLEFHW antenna: Ready for Action
In the last post I introduced a crazy, off-the-wall idea for a variation of the popular End-Fed Half-Wave (EFHW) antenna. I called it the CLEFHW - Coil Loaded End-Fed Half-Wave. Its purpose is to allow backpack portable operation of an electrical half wavelength antenna without the need for a tree or pole to suspend a … Continue reading CLEFHW antenna: Ready for Action
The QMX is Full of Holes, Here’s the Essential Fix!
When the design team at QRP Labs (alright, we know that means just Hans) set out to produce a multiband portable transceiver that would be packed with advanced features and could be sold for as little as a meager purse of groats, what was their primary design objective? You can bet your life it was … Continue reading The QMX is Full of Holes, Here’s the Essential Fix!
Antenna Height Matters – True or False?
How often have you read that an antenna should be placed as high as possible - the higher the better? Is it true? My inner skeptic says "hmm, maybe". It's certainly an aphorism that is open to scrutiny. Aphorism? The American Heritage® Dictionary of the English Language defines "aphorism" as: "a tersely phrased statement of … Continue reading Antenna Height Matters – True or False?
