About 20 years ago a Canadian company, based in Quebec, produced a compact QRP antenna called the Miracle Whip. It was a really good piece of engineering that relied on the principle that a short whip has capacitive reactance that can be cancelled by feeding it through an inductive reactance. Remember, resonance occurs when capacitive … Continue reading A Born Again Miracle Whip
Radio Man Won’t You Come and Fix my Radials?
My humble apologies to the former Canadian folk music band Tanglefoot who came from the general area I live in. I borrowed (and edited) one of their song titles for this post. Just when I thought I had the theory and practice of ground radials down pat, along comes another surprise. After several months of … Continue reading Radio Man Won’t You Come and Fix my Radials?
So, is the VP2E Antenna Directional Enough?
Another fine day in February in Southern Ontario saw me out on a beach on the southern shore of Georgian Bay testing my unbalanced version of the VP2E antenna. In the previous post I shared my observation, from EZNEC modeling and a trial POTA activation, that moving the support mast towards the feedpoint end of … Continue reading So, is the VP2E Antenna Directional Enough?
The VP2E – A Strange (But Proven) Antenna
As an avid POTA activator I was quite excited to come across a new-to-me wire antenna that is rapidly field deployable, fairly stealthy, directional and which has some gain. I would like to thank Germany-based SOTA operator Ed Durrant DD5LP, G8GLM, VK2JI for introducing me to the VP2E. As is my custom, I read Ed's … Continue reading The VP2E – A Strange (But Proven) Antenna
What in Heaven’s Name is a Rybakov Antenna?
I love to check out interesting, new antenna designs. The Rybakov isn't actually a new antenna, it has been around for a while; either I just hadn't come across it before or I had passed it over and forgotten about it. So when I read about it recently I just knew I had to find … Continue reading What in Heaven’s Name is a Rybakov Antenna?
20m Band – The Long and the Short of it
Another recent POTA activation turned out to be a useful learning experience for me. It was a moderately cold February day. The temperature had dipped to -20degC overnight, but by afternoon it had risen to a relatively balmy -7degC. It was also the occasion of the Polar Bear QRP Ops February Polar Bear Moonlight Madness … Continue reading 20m Band – The Long and the Short of it
A Directional Antenna With Just One Straight Wire – Crazy?
Being called crazy is a compliment to my ears. It means I am doing something different, something unusual. I strive to be "crazy" every day. It is only by doing crazy stuff that we innovate and discover new ideas and new ways of doing things. Today I decided to do two crazy things. First, I … Continue reading A Directional Antenna With Just One Straight Wire – Crazy?
I Fell Off the QRP Wagon and Regretted It Already
Only use enough power to make the contact. That's the advice often given to hams. How much is enough? One way to find out is to get on the air and start making waves. Or, I thought, check the propagation numbers, evaluate the site elevation and make a turkey-brained guess about how much power I … Continue reading I Fell Off the QRP Wagon and Regretted It Already
A Magic Ground Mobile Antenna
Let me start by confessing; I don't operate HF mobile. So my "mobile" HF antenna is only suitable for stationary "shack-in-a-truck" operations. Driving requires my full attention ... and so does CW operation! I mount one of my two portable vertical antennas on a short aluminum pole which in turn is mounted on the hitch … Continue reading A Magic Ground Mobile Antenna
Pairing the PFR-3 with an EFHW Antenna
My previous outing with my trusty old Hendricks PFR-3 portable field radio (see QRP on Deck) was with a Random Wire antenna. The big advantage of the random wire is that it is non-resonant on any band and can be tuned on any band. I prefer to use resonant antennas that can be paired with … Continue reading Pairing the PFR-3 with an EFHW Antenna
