How to Prep for Radio Camp

What is a "Radio Camp"? Put simply, a Radio Camp is a rapidly deployable temporary setup established for the primary purpose of operating ham radio outdoors. It is not quite the same as a traditional vacation or RV camp. A Radio Camp might be setup for a very short period (e.g. for the duration of … Continue reading How to Prep for Radio Camp →

9:1, 4:1, 1:1 or None:None?

When using a Random Wire antenna (also known as an End-Fed Random Wire - EFRW), the impedance at the feed end of the wire is usually higher than 50 ohms. In order to maintain a good match with a transceiver some form of impedance transformation is required to minimize SWR losses in the antenna system. … Continue reading 9:1, 4:1, 1:1 or None:None? →

Ditch That Automatic Tuner!

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. For a few weeks I have been operating my Yaesu FT-891 with an LDG Z-11 automatic antenna tuner, but there are … Continue reading Ditch That Automatic Tuner! →

The Hidden Secret in CW’s PARIS Standard

Sending speed in Morse Code (CW) is measured in words per minute, but how long is a "word"? In the English language the simplest word is the indefinite article "A". A contender for the longest word may be the name of a village in Wales called Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch. So the word PARIS has been chosen to … Continue reading The Hidden Secret in CW’s PARIS Standard →

A Born Again Miracle Whip

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 →

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 →

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 →

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 →

Snow and Freezing Spray – QRP Madness

Saturday 7th January was the date of the first Polar Bear Moonlight Madness Event (PBMME) of the year. In fact, as a new member of the group, it was my first ever PBMME. The group is called the Polar Bear QRP Ops. It is an amateur radio group who are active with portable QRP operation … Continue reading Snow and Freezing Spray – QRP Madness →
