5 Tips for Field Expedient Radio Operations in the Big Blue Sky Shack

I first became interested in operating amateur radio in the great outdoors (aka the Big Blue Sky Shack) over 20 years ago and since that time it has become a passion. The passion is partly inspired by the exploits of secret agents behind enemy lines during the Second World War. These people didn't have to … Continue reading 5 Tips for Field Expedient Radio Operations in the Big Blue Sky Shack →

A Versatile Solution for Backpacking with the QRP Labs QMX

Solar cycle 25 is rapidly approaching its peak. That means propagation conditions are very favorable for QRP operations again. Add to that the ever increasing popularity of outdoor operating programs like Summits on the Air (SOTA) and Parks on the Air (POTA) and there has never been a better time to hit the Big Blue … Continue reading A Versatile Solution for Backpacking with the QRP Labs QMX →

Venturing Outside the Box with the End-Fed Half-Wave Antenna

So many words have been written about the popular End-Fed Half-Wave antenna that you would think it would be "settled science" by now. For several years I have been building EFHWs according to accepted wisdom, but my inquisitive mind always seeks to question why they are built that way and could they be improved? You … Continue reading Venturing Outside the Box with the End-Fed Half-Wave Antenna →

An Improved Self-Supporting, Low Footprint Field Expedient Antenna for 20m

In my post https://hamradiooutsidethebox.ca/2024/02/28/field-testing-the-antenna-called-long-tall-sally-oops-and-downs/ I wrote: Now what if it were possible … … to maintain the small footprint on the ground while simultaneously reducing the height of the antenna. Could it be done? That’s a project I am working on now. I have some ideas that I think are going to work. Stay tuned. … Continue reading An Improved Self-Supporting, Low Footprint Field Expedient Antenna for 20m →

Antennas: a Riddle Wrapped in a Mystery Inside an Enigma

I owe the title of this post to Sir Winston Churchill who once used it to describe a country that is prominently in the news at the present time. It seemed an appropriate description for ham antennas too because the more I know about antennas, the more I realize how much I don't know. Maybe … Continue reading Antennas: a Riddle Wrapped in a Mystery Inside an Enigma →

Field Testing the Antenna Called “Long Tall Sally”: Oops and Downs!

A couple of weeks ago I wrote a post about a new vertical antenna concept that I dubbed "Long Tall Sally". To recap; I wanted a field portable antenna that occupies a very small footprint. The trade-off of a reduced footprint is an increase in height. This involved stretching a quarter-wave vertical for 20m into … Continue reading Field Testing the Antenna Called “Long Tall Sally”: Oops and Downs! →

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 →

Can a Manual L-match Get the Job Done?

Or can it be made just a little bit better? In part 3 of my manpack series of posts I discussed how and why I replaced a perfectly good LDG Z-11 Pro autotuner with a home-made manual L-match. To summarize, the autotuner was doing a great job but was using too much space inside the … Continue reading Can a Manual L-match Get the Job Done? →

Building a Manpack – Part 2, the QRP Rig

As in Part 1, 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. Complete station fits into a plastic "50 caliber ammo case" The complete station - radio, battery, paddles, phones and antenna fits neatly … Continue reading Building a Manpack – Part 2, the QRP Rig →

Building a Manpack – Part 1, the Antenna

To start, 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 . The HFpack group of /PM enthusiasts are the experts in operating Pedestrian Mobile. Personally I prefer the Pedestrian Stationary style of operating. The … Continue reading Building a Manpack – Part 1, the Antenna →
