Magically transform a single band ground plane into a multiband antenna – instantly

I call it "electromagnetrickery". You can learn a lot by building your own antennas, much more than if you buy commercial ones. But beware, it becomes addictive - I have a drawer full of empty wire spools to prove it. Sometimes the behaviour of those pesky electromagnetic wavicles delivers unexpected surprises. Here is the story … Continue reading Magically transform a single band ground plane into a multiband antenna – instantly →

A Radio Road Trip with the QRP Labs QMX – lessons learned!

The XYL and I took a short break from routine and drove up to Ontario's Muskoka region for 4 days of recreation and radio activity. I packed my QRP Labs QMX transceiver and a selection of antennas hoping to complete a couple of POTA activations. Tour boats moored at Gravenhurst wharf on Lake Muskoka Muskoka … Continue reading A Radio Road Trip with the QRP Labs QMX – lessons learned! →

Today’s Weather: 6000 degrees Celsius with a possibility of storms

Sample Solar-Terrestrial Data Table from https://www.hamqsl.com/solar.html HF propagation forecasts have always baffled me. A quick look at the forecast chart produced by Paul N0NBH on his excellent website at: hamqsl.com/solar.html reveals a dizzying collection of data from which Paul draws a conclusion about conditions on each of the HF bands. His forecasts are usually correct, … Continue reading Today’s Weather: 6000 degrees Celsius with a possibility of storms →

A Most Unusual Vertical Antenna for 20m

There has been quite a lot of online discussion recently about minimizing ham footprints, reducing environmental impact and showing respect for other public space users. Parks on the Air (POTA) has been indelicately described as a 500 pound gorilla due to its immense and still growing popularity among hams. As that growth continues there is … Continue reading A Most Unusual Vertical Antenna for 20m →

Building a Manpack – Part 3, the QRO Rig

As in Parts 1 and 2, let me define what I mean by "manpack". My manpack is a manually transportable, rapidly deployable, field expedient complete radio station for operating while pedestrian mobile or pedestrian stationary. Why QRO? I have to admit, I love QRP; I started my HF career as a QRP operator and I … Continue reading Building a Manpack – Part 3, the QRO Rig →

Is Your Rig Rugged Enough for Field Deployment?

The term "field deployment" can be interpreted in many different ways. To some it could be as simple and easy as setting up inside a warm, dry, comfy vehicle - although I'll admit it can get darn cold inside a vehicle in winter at northern latitudes. Up, Up and Away Field deployment can also mean … Continue reading Is Your Rig Rugged Enough for Field Deployment? →

New Life for a 15 year-old Hendricks PFR-3 QRP Radio

Desperation often leads to innovation, so they say. My order for a QRP-Labs QMX radio is so far down the waiting list that I won't take delivery for several months yet. Why is it that some QRP radio manufacturers have such long waiting lists for their products? It could be that their products are very … Continue reading New Life for a 15 year-old Hendricks PFR-3 QRP Radio →

A New FT-891 Ammo Case Go-Box for POTA

My inner voice recently told me to stop building, re-building, re-engineering and modifying my outdoor operations kit and just go get on the air with it. I told my inner voice to hush-up; I need to do this. Each iteration of my design feels like the ultimate build - until it has been out to … Continue reading A New FT-891 Ammo Case Go-Box for POTA →
