A shelter for Winter Field Day operations in a field
Field Report: Winter Field Day with a New Antenna
Winter Field Day (WFD) 2022 found me operating indoors, despite my best intentions to get out in the field. I was recovering from a bad cold, and did not want to risk having complications arise from sitting out in the cold and damp. So for WFD 2023, outdoor time with my radio was a must. I wanted to operate a 1-Oscar station, and to do that I had to set up more than 500 feet from my home QTH. So a site next to the pond in our back field, about 800 feet from the house, became my WFD shack.
I started planning and collecting kit for the operation in mid-January, with the long term forecast hinting at near-freezing temperatures with the potential for rain or snow. Let me introduce you to my WFD station.
Shelter
A shelter was needed to keep out rain and snow, and to provide a barrier against the winds whipping across the adjacent field. A few poles lashed together, and steadied by stakes, provided the frame to support the shelter. With a poly tarp secured to this frame, the resulting a-frame shelter, while not completely enclosed, did provide effective weather protection for both operator and equipment. There was about 3 inches of snow on the ground when I set up the shelter, and I was able to pile some of it along the bottom edge of the tarp to keep the wind from getting under it.

Antenna
I know that when setting up a station, the antenna is not generally the first thought, but I had recently finished building a homebrew 9:1 random wire antenna with a 144 ft radiating wire, and I wanted to test it out. There are better ways to put a new antenna on the air, but the opportunity was a good one. Besides, I had backup antennas that could be quickly substituted if the need arose. In the event, things worked well, and the antenna proved agile and capable on all activated bands. I particularly wanted to see if it would tune on the 160m band. More on that later.
The feedpoint of the 9:1 random wire antenna is built into a wire winder to support transport, deployment, and recovery for field use. The RF functional components include a female BNC connector, a 9:1 unun, and miniature banana jacks for connecting the radiator and counterpoise wires. There is no wire on the winder, because a corner was broken off during WFD deployment, and a mechanical repair is needed. (Click to enlarge)The 9:1 unun is mounted near the BNC connector, and is electrically connected to a one miniature banana jack for the radiator and another for the counterpoise. The unun and wiring are covered with hot melt glue to provide mechanical integrity and protection from the weather.
Radio
The goal of trying the antenna on 160m left me with only one choice for a radio. I would use the Lab599 TX-500 Discovery, because it is the only transceiver among my field rigs that is capable of operating on the 160m band. Since a tuner is required, I paired it with an LDG Z-11Pro II, a wide-range autotuner. I also included a Monitor Sensors Power and SWR Meter in the feed line to help assure that I was legitimately running less than 5 watts to qualify for the QRP power multiplier.

Recipe for a Failed Activation at K-0619?
by Brian (K3ES)
A couple of days before Christmas, high winds came, temperatures dropped, and 3 inches of snow made a real nuisance of itself by blowing around and re-covering anything that was swept or shoveled. With daily high temperatures below zero (Fahrenheit) and wind gusts over 40 miles per hour, the weather just didn’t make for much fun outdoors. In fact, we hunkered down and didn’t get beyond the end of the driveway for four days. So when the winds calmed and temperatures rose, I really needed to get out of the house for a bit. What better way than to walk up the road and activate K-0619? Even with temperatures in the low 20s, I should be able to finish a quick activation. And so it was planned…
Of course just before walking out the door, it is always prudent to check on band conditions…
What did the sun just do to me, and how will I ever make 10 contacts on 5 watts before my fingers freeze???
Alright, I really need my outdoor time. Even if it means that I fail to activate the park this time, I’m going for it!!!
I walked down the driveway…
Off to the woods we go…
…up the road…
Fortunately the hike is less than ½ mile…K-0619, Allegheny National Forest…
… and into the woods.
Snowy, peaceful, and lots of trees to support my antenna.

K3FAZ, K3STL, and K3ES POTA in the Cold with a Bonus Gear Report
K3STL and K3ES at the entrance to K-0621.
by Brian (K3ES)
K3ES Perspective
Saturday November 19 dawned clear and cold in northwest Pennsylvania, but the truth is that I was up well before dawn. The third Saturday of each month, I try to make the 2 hour drive south to help with Skyview Radio Society’s monthly Volunteer Examiner (VE) testing session for new or upgrading licensees. Clear skies (which matched the forecast) meant that road conditions would not be a problem. So, shortly after 5 am I pointed the truck south.
One of the creature comforts I appreciate about our VE session is meeting for breakfast before the test. It was obvious on arrival at the restaurant that the VEs would greatly outnumber the test candidates, but many hands make light work. Coffee and an omelet definitely helped fuel the effort. Since the test sessions normally last less than 2 hours (and that held true this time), three of us VEs had made plans for post-test session POTA.
Before launching into the field report, let me acknowledge that K3STL’s photography was instrumental in providing a report with visual appeal. Personally, I almost always forget to take the pictures.
POTA Plan
John “Tall Guy” K3STL, Steve K3FAZ, and Brian K3ES in the parking lot at K-0621.
The plan for the day was to attempt activation of two POTA sites, Beechwood Farms State Conservation Area (K-0620) in suburban Pittsburgh, and Todd Sanctuary State Conservation Area (K-0621) about 20 miles further to the northeast. John “Tall Guy” – K3STL and Brian – K3ES would do a short activation of K-0620, then meet Steve – K3FAZ at K-0621 for the rest of the afternoon.
Knowing it would be a cold day for mid-November (temperatures peaked for the day just barely above freezing), each of us made plans to adjust for operating from our vehicles. That meant that we would be doing parking lot activations at both locations. While we each normally activate with slightly different operating styles that are suited to outdoor POTA operations, some tweaks made it possible to have wind and weather protection for this outing. In hindsight, it was a perfect choice.

Field Report: Reflections on a Kilo at Cook Forest State Park
by Brian (K3ES)
Contemplating my favorite antenna tower during the Kilo activation.
Cook Forest State Park in northwest Pennsylvania has always been a special place for me. It abounds in trees (including some of the last virgin timber around), wildlife (deer, turkeys, song birds, squirrels, and the occasional bear), and also includes the scenic Clarion River. When I found out about Parks on the Air (POTA) after getting licensed in 2020, I knew that I had to put POTA entity K-1345 on the air.
Our family cabin; which has been central to all of the phases of my life – including milestones, joys, sorrows, and unadulterated wonder – is located on a plot of land bordered on two sides by the park. It just seemed natural and right for me to do my first-ever POTA activation under an ancient hemlock tree just a few steps over the line from the back corner of our property. That mostly-SSB activation happened in May 2021 with my TX-500 pushing 10 watts into a homebrew dipole suspended from a dead branch up 30 ft in the hemlock.
An early activation of K-1345 from beneath the ancient Eastern Hemlock Tree
Last weekend, I reached a meaningful personal goal by completing my 1000th activator contact from K-1345. After the first activation I never again operated mostly-SSB, and I never increased radiated power. Nearly all of my contacts since have used CW, and many were completed at 5 watts. The added challenge of QRP CW undoubtedly made the Kilo more difficult, but it was also much more fulfilling. It has taken me 28 successful activations, a lot of work to improve my CW skills, and a lot of patient support from the hunters who have shared this journey with me.
My activations at K-1345 tell the story of my journey as a CW operator. I took my first steps on that journey in late 2020, months before I had a portable radio or a plan for my first activation. I started with an Android app, V-Band, and listening to CW exchanges on webSDR. Eventually that progressed to CW Academy basic, intermediate, and advanced classes. The classes really upped my CW game, but what helped even more was using CW on the air. I finally got my HF station on the air in March 2021 and started hunting parks, SSB at first, then increasingly CW. During my first mostly-SSB activation I did manage to hunt down three park-to-park contacts using CW. I started my second activation by calling CQ using CW, and I have not looked back. Wow, those hunters were patient during that first first CW activation! My skills have improved greatly since then, but I’m still not where I want to be. The next goal for me is to gain confidence and proficiency in less-structured QSOs.
I want to thank Thomas – K4SWL, whose real time, real life activation videos challenged, motivated, and inspired me to learn and use CW. I greatly appreciate the work of the CW Academy advisors who guided me through some of the hard work needed for improvement. I also need to thank the hundreds of hunters who have patiently endured my developing CW skill set. Finally, my hat is off for the dedicated POTA volunteers, who continue to improve and expand this amazing activity to the benefit of radio amateurs around the world.
Completing the Kilo activation would have taken me longer if it were not for the tremendous encouragement provided by my gracious, intelligent, and beautiful XYL. As I was contemplating indoor chores on a Friday morning, she pointed out the opportunity to go out and activate during the best weather of the weekend, and save the chores for a rainy day. Who am I to argue with such impeccable logic? Off to the woods we went!!!
I made a point of using the TX-500 with the homebrew dipole suspended in that ancient hemlock tree to complete the Kilo activation, going back toward the starting point, as it were. Of course I did finish with CW mode and 5 watts to commemorate my personal growth during the journey, too. I was set up to go by mid-afternoon. Needing 57 contacts to complete the Kilo, I decided to get some contacts on 20m, then move to 40m a bit later.
Getting started on 20m.
After calling CQ for almost half an hour to get two contacts, I decided to move to 40m a bit sooner than planned…
With the antenna lowered, I am reconnecting the links for 40m.
40m was hot! I completed the eight additional contacts needed for a successful activation in less than 15 minutes. By the 2 hour mark, I had racked up a total of 69 contacts and finished the Kilo.
As a final note, I picked up 55 more contacts on Saturday, bringing my total CW mode contacts over 1000. The rain started early Sunday morning, and I got my indoor chores finished after all.
