Unveiling Poland: POTA, SOTA, and a Glimpse into History – Part 1: The Rover Award

7 Comments

by Thomas (DM1TBE as SP/M0KEU/P)

Just like last year, my family and I combined a visit to my parents near Berlin, Germany in the summer with some extra days in the region. As in last year, we went to Łagów (German: Lagow) in Poland.  The reasons we chose Łagów again, was a lovely holiday house, directly on a beautiful lake with a beach – all not too far away from Germany – and the good memories we had from our previous stay.

There is also a SOTA summit, which was only activated once in the 5 years when we visited the area last year. As I started with POTA this year and there are also a couple of POTA spots around, I thought it would be worth another visit.

The area around Łagów has been populated since the Bronze Age, i.e. >1000 BC. In 1251, the area came under German rule and the first mention of the town was in 1299. In the 14th century, the Knights Hospitaller built a castle that exists to this date. For the year 1367, it is documented that the convent of Lagow consisted of seven knights and one priest of the order.

At the foot of the fortress, a settlement for craftsmen and servants emerged, secured by defensive walls and two gates.

Gate in the middle

It is obvious that the builders of the gates did not have modern cars in mind when planing the size of the gates.

During the Thirty Years’ War, one of the longest and most destructive conflicts in European history, Lagow was captured and destroyed by the Swedes in 1640. The hand drawn map below from 1662 already shows Lagow.

During the fighting at the end of World War II in the spring of 1945, the castle and the village did not suffer mayor damages. After the war’s end in 1945, Lagow was placed under Polish administration, and Polish migrants settled in the area. The local Polish authorities expelled the native German residents who had not fled. The spelling of the town’s name was changed to Łagów.

Germany lost large parts of its territory as a consequence of the wars it has started after both major wars of the last century. Lagow was part of the lost territory depicted in the green area below.

The territorial gain probably wasn’t something Poland was very happy about, as the Soviet Union annexed a significant portion of Eastern Poland at the same time and incorporated the previously Polish soil mainly into the Soviet Union republics of Ukraine and Belarus. Consequently, the country experienced an effective westward shift.

Red: Pre-war Poland, Pink: Post-war Poland

Over a long time, expelled Germans were very vocal about claims to return the area to Germany and yet rather quiet about their share in the terrible events that unfolded between 1933 and 1945. Therefore, Germany’s eastern border was not recognized until 1990 by the German government. However, the issues resolved over the time and today, 33 years after the official acceptance of the border, no one I know even thinks about this as an issue any more. Additionally, the Polish side appears to be more relaxed about this topic. I have seen a lot of bilingual information panels and some memorials for former German inhabitants. Nice to see the wounds heal.

The Activations

The holiday house was within the borders of a POTA park. Having a 7-year-old “early bird” son, helped my to wake up early enough to get my 100 contacts for the POTA Early Shift Activator Award.  I walked to the edge of the facility and raised my SOTABEAMS Band Hopper III linked dipole for the 20-, 30- and 40 meter bands as soon as my son woken me up and ended my activity around 9:00 local time nearly every day.

Although I had a bunch of other antennas with me, I made all activations during my journey with this antenna and an Icom IC-705.

POTA Rover Warthog Award

The density of POTA-parks is way higher in Poland than in my home region in Southern Germany.  With the help and tips from Damian (SP9LEE) I drafted a plan to activate 5 parks on a single day. Continue reading Unveiling Poland: POTA, SOTA, and a Glimpse into History – Part 1: The Rover Award →

POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock!

2 Comments

After a fun little activation of Lake James State Park (K-2723) on the morning of Monday, July 31, 2023, I decided to fit in at least one more POTA adventure on a mini rove.

The logical choice was Table Rock Fish Hatchery since it’s such a short drive from Lake James and I always enjoy activating that particular site.

The weather that morning was beautiful and so was the drive.

Table Rock Fish Hatchery (K-8012)

I pulled into the driveway of the picnic area and–no surprise here–I had the place to myself.

In fact, according to the POTA website, I’ve activated this site 12 times and I’ve never seen another soul in the picnic area save my canine friends, park staff, and one guy who was hunting muskrats in the creek. That’s about it. Never anyone actually hanging around the picnic area.

On the drive over, I hadn’t considered what antenna or radio to use–I had a few in the back of my car.

I thought about using my Elecraft KX1, but then realized I didn’t have an extra shielded audio cable to connect to my Anker Soundcore Mini speaker nor did I have my in-line digital audio recorder. Without those things, I wouldn’t be able to make a video of the activation.

My next choice was the Yaesu FT-817ND and, in fact, it would be ideal. I was looking forward to putting the ‘817 on the air again–it’d been a couple of months!

First, though, an antenna. I pulled out the 40 M End-Fed Half-Wave Steve (MW0SAW) made for me some time ago.

This antenna has been in heavy rotation lately because it’s been in my main radio backpack as I’ve been traveling around the region.

I deployed the EFHW in short order, then hooked it up to the ‘817. Continue reading POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock! →

Guest Post: A wildly successful POTA activation…on a whim!

Many thanks to Mike (KE8PTX) who shares the following field report:

One of my best POTA activations on a whim.

by Mike (KE8PTX)

Monday 8/15/2023

Doing some late afternoon POTA chasing from the back deck home QTH,  contacts on 5 watts seemed to be coming fairly easy so I started to think I should have a go at it and activate a park.

One in one hundred times I activate QRO, so I decided to take the FT-891 and blow the dust off the finals.

When filling my pack, I had a last minute change of heart and decided to stick with QRP.  Bagged up the never fail KX2 field kit and hit the road.

The park was Port Huron State Game Land (K-6762) a nearby game land with many activation spots.  As I never do look at the solar reports, this time was no different.  I feel the solar reports more times than not would keep me home. With a QRP mind set we all feel we have something to prove by just doing it.

So off to the park we go!

After a short 20 minute dive through the countryside of the Michigan thumb, I arrived at my location only to be welcomed by a flock of Michigan state birds: the mighty Mosquitoes.  I came prepared with my trusty Thermacell.  Fired it up 5 minutes before exiting the car to give it a head start.

My deployment of gear is simple and quick.  My go-to antenna is a 40m EFHW inverted V configuration running North to South.

My mid support is a modified Carbon 6 mast.

Setup time was less than two minutes and I was on the air. Continue reading Guest Post: A wildly successful POTA activation…on a whim! →

Matt’s Low-Profile POTA Activation at the San Francisco Maritime National Historic Park

SF Maritime NHP POTA Activation

by Matt (W6CSN)

There are several Parks On The Air eligible parks in San Francisco and the northern tip of the peninsula of the same name. One would expect that a POTA activator that calls this city home, would have logged activations from all of these parks, but so far this one has eluded me.

Muni Pier (closed) across Aquatic Cove

The San Francisco Maritime National Historic Park (K-0757) sits at the northern edge of the city, right next to the Fisherman’s Wharf area that is so popular with tourists visiting San Francisco.

NPS Map of SF Maritime NHP

The National Park encompasses an area that includes the municipal pier, aquatic cove with its small public beach, the art deco style Maritime Museum, and Hyde Street Pier with its floating collection of historic ships.

The historic ships alongside Hyde Street Pier

For various schedule and logistical reasons, K-0757 was the one park in the city that I had not yet activated. So today, when my daughter wanted to visit the ships, I made sure to have my lightweight POTA “go” pack with me in case I found an opportunity to attempt an activation.

I’d say the main attraction at Hyde Street Pier is the Balclutha, a steel hulled, square rigged, cargo ship built near Glasgow, Scotland and launched in 1886.

Balclutha – a survivor from the Age of Sail

Balclutha is continually undergoing restoration and maintenance by the Park Service and skilled volunteers. Her many careers on the world’s oceans are documented with numerous interpretive stations and exhibits, both topside and below decks.

We wrapped up our tour of the vessels on the pier by exploring C.A. Thayer, a 219 foot long sailing schooner built in 1895 near Eureka, California to serve the coastal timber trade.

Eureka is a steam powered ferry that served on SF bay.

I was thinking about where to activate and not really looking forward to setting up on or around the public beach. Between the Aquatic Cove swimmers, people enjoying the beach, and tourists going to and fro, there wasn’t really an “out of the way” location to setup even a small station.

Hyde Street Pier itself was actually pretty quiet, but I wasn’t about to set up my station there without prior approval of park staff. Just as we were about disembark from Thayer I noticed an NPS employee near the gangway, and so I took the opportunity to inquire about setting up my low impact, leave no trace, POTA station.

It turns out the person I talked to on the deck of C.A. Thayer was the supervisor of the SF Maritime National Historic Park! He is keenly interested in radio and was even aware of recent solar activities that have given us amateurs a mixed bag of propagation conditions. He agreed to my request to set up at the end of the pier, past Balclutha’s gangway.

Is Balclutha’s steel hull a reflector of radio waves?

I used the Gabil GRA-3750T antenna with its stock telescopic whip tuned for 20 meters. This is the most low profile antenna I can field for HF. Yes, it’s a compromised antenna system but as you’ll see it works good enough. Continue reading Matt’s Low-Profile POTA Activation at the San Francisco Maritime National Historic Park →

POTA Field Report: A Morning 40 Meter QRP Activation at Lake James State Park!

3 Comments

On Monday morning (July 31, 2023) I left the QTH with POTA on my mind.

As I mentioned in a previous post, July was a busy month and I was in desperate need of some POTA Therapy! Fortunately, I had the full morning to play radio, so I plotted a two (or possibly three) park rove, starting with Lake James State Park.

Lake James State Park (K-2739)

I arrived at Lake James a little after 9:00 AM and pretty much had the park to myself.

In order to keep my setup time a little on the short side, I chose a picnic table next to my car.

I grabbed my throw line cube and (1st gen) Red Oxx Micro Manager pack in which I’d packed my Discovery TX-500 and accessories.

Since it was in the morning, I planned to spend time on the 40 meter band and, hopefully, work a number of hunters in the surrounding states.

For this activation, I paired my Discovery TX-500 with MW0SAW’s 40 meter end-fed half-wave antenna.

I powered the TX-500 with a homemade 5Ah LiPo battery my friend Joshua (N5FY) sent me a couple months ago.

Of course, since I was using a 40 meter end-fed half-wave antenna, I didn’t need an ATU for 40 meters (or 20, 15, or 10 meters for that matter). Continue reading POTA Field Report: A Morning 40 Meter QRP Activation at Lake James State Park! →

VE6LK makes a quick trip to Montana o/a AI7LK – Day 2

2 Comments

by Vince (VE6LK)

As you read in day 1 of this story, I landed up in Montana opportunistically. The plan for day 2 was to say goodbye to our visiting family, then make our way north from Kalispell, MT via Eureka, MT and head for home. We’d stop on the way to visit with friends and, of course do one more POTA activation.

Operating position at K-4848. This spot is at the south end of Lower Stillwater Lake.

After departing Kalispell we arrived at Lower Stillwater Lake, part of K-4848, at around 11am MT.

There is one picnic table near a boat launch and it was vacant so I got to work quickly and set up. I had brought along a lightweight kit consisting of my VE6VID EFHW, Elecraft AX-1, the KX3, a battery, a key, a paper logbook and some extra bits like carabiners, a bit of masonry string and a small mast that I landed up not using. With my wife and doggo along for the ride, I didn’t want to take too much time to set up and operate, so the natural choice would have been the Elecraft AX1 antenna, but with conditions being as soft as they were a day earlier, the resonant wire antenna seemed the better choice for the extra 5 minutes it would take to set up.

This short video shows my full set-up:

I looped the feedpoint end around a nearby tree branch and unrolled the antenna and tossed it up in a branch just out of my reach – another low-slung wire antenna! The rest of the gear came out on the table and I used the tote box as a makeshift stand for my shortie camera tripod. Continue reading VE6LK makes a quick trip to Montana o/a AI7LK – Day 2 →

From the Archives: A 2022 Postcard Field Report and Activation Video from New River Gorge National Park

3 Comments

These are busy days for K4SWL

These past few weeks have been absolutely crazy for me in terms of activity–I’ve been traveling a lot, doing (involved) DIY projects on the house, searching for a new car, planning a PV system for the QTH, fixing well pumps, helping friends, and doing caregiving for my folks.

It’s all kept me very busy!

I have a sizable backlog of emails that have accumulated during this time. If you’ve sent me a message, I likely haven’t read it yet. Apologies for that. I simply haven’t had time to read and reply.

I thought about skipping a field report this morning, then I remembered an amazing West Virginia camping trip and draft videos I’d already uploaded to YouTube.

In lieu of writing a full field report (and so that I can share a video today) I thought I’d simply share this activation video with a Postcard type field report.

2022 West Virginia POTA Camping Trip

Last year (2022), in lieu of going to the Dayton Hamvention, my buddies Eric (WD8RIF), his son Miles (KD8KNC), and I spent a long weekend activating parks and camping in the New River Gorge area of West Virginia. Click here to read more about that trip.

The camping trip was absolutely amazing and we activated a number of parks during that time.

I made activation videos at most of the parks we visited, but with my summer travels and activations in Canada last year, I skipped over several of the videos I’d uploaded so that I could publish my Canadian activations while I was still in Canada.

New River Gorge National Park (K-0696)

 

The following activation video was made on May 21, 2022 as WD8RIF and I activated K-0696.

 

I’ve yet to re-watch this video myself, but I remember clearly that this particular day we had atrocious band conditions.

Indeed, rough bands were present during much of our weekend camping trip, but it never stopped us from having fun or activating our parks.

In terms of gear, I used my trust Elecraft KX2 paired with my Chameleon MPAS 2.0 antenna system.

POTA on Mount Mitchell: The new REZ Ranger 80 and how to use the Over/Under method to coil wire and cable

1 Comment
The REZ Ranger 80 antenna system ships with everything you need, including a nice backpack.

Back in March, I received an email from Mike Giannaccio (W5REZ) the owner of REZ Antenna Systems–he was curious if I’d like to check out his REZ Ranger 80 antenna system.

At the time, my plate was pretty full, so he arranged to send it to me on loan in July.

If you’re not familiar, the Ranger 80 is a portable vertical antenna with a tuning coil at the base that employs a sliding tap for tuning. The Ranger 80 will cover anywhere from 80 – 15 meters without needing any sort of external matching device (like an ATU).

The Ranger 80 Tuning Coil.

If you’re familiar with the Wolf River Coils antenna systems, then you’re familiar with this type of vertical antenna. The difference is that the Ranger 80 is built to what I could only describe as MilSpec standards.

Much of the Ranger 80’s components are CNC machined from premium materials. It sports a Delrin body, black anodized 6061 aluminum, and all stainless steel hardware.

This is not a featherweight antenna: it has the heft to match the caliber of materials used in its construction. It’s not an inexpensive antenna either–it’s currently about $560 US at DX Engineering.

The base of the Ranger 80: note the beautifully CNC-machined holes for the four counterpoises.

The Ranger 80 is also rated for 500W SSB and 250W CW/Digital–in other words, quite a bit more power than I’d ever use in the field, but this design will make activators and field ops happy that like to push some wattage.

I was curious how easy the Ranger 80 would be to deploy and tune, so on Sunday, August 6, 2023, I took it to one of my favorite parks on the planet.

Mount Mitchell State Park (K-2747)

I wasn’t alone on this trip: it was a proper family picnic with my wife, daughters and, of course, Hazel.

The weather was very moody that day–driving up to the park, we watched clouds and mists rise up through the trees like waves crashing on a rocky coast line. Continue reading POTA on Mount Mitchell: The new REZ Ranger 80 and how to use the Over/Under method to coil wire and cable →

K3ES’ Hike with Molly: The POTA Dog In-Training!

“Hey!  I can be a POTA Dog.  Let’s go on a hike!”

A Hike (and Activation) with a POTA Dog In-Training

by Brian (K3ES)

PA State Route 66 Trail-head on K-4239

A plan for a Hike and an Activation

A couple of Wednesdays ago, I decided to take a hike along the North Country Trail.  It would not only provide some needed exercise on a beautiful day, but it would also take me into Pennsylvania Game Land #024, enabling a 2-fer activation of K-4239 and K-8725.  I had hiked this stretch of the trail several times before, so I figured it would be safe taking one of our dogs along for the trip.

Jojo (front) and Molly (back) are not happy about this staged picture.

Molly and Jojo are two rescued Boston Terriers, who have made our home their own since October of last year.  Each has her own character.  Molly is exuberant, very friendly, and frankly, a bit of a bulldozer.  Jojo is pure sun bunny, preferring to find a bright patch of lawn, then lay there soaking up the heat.  Once installed in a sunny spot, Jojo doesn’t like to move.  So, it seemed natural to invite Molly along for the afternoon hike.  The only potential issue was the planned stop for a park activation.  I was almost certain that Molly would enjoy the walk, but how would she handle the period of inactivity?  There was only one way to find out.

Jojo in her natural habitat:  sunbathing in the back yard.
Molly on the run.

Since solar conditions had been keeping the radio bands rough and unpredictable, I decided to start my QRP CW activation in the middle of the afternoon.  Beginning the activation at 3pm EDT meant that my first hour would overlap with the popular CWT sprint, so I planned to start on the 30m band to avoid trying to compete with my 5 watt signal.  More importantly, the timing would let me finish on the 40m band later in the afternoon, when I have always found it to be productive.

Molly supervises CW operations during the 2-fer Activation.

The plan was set and an activation was scheduled in POTA.app to begin at 3pm EDT, so detection by the Reverse Beacon Network (RBN) would assure automatic spotting.  We left home just after 1pm, drove to the trail head, and started our hike to the activation point.  Our travel and the station setup went quicker than expected.  Even after securing Molly on her leash, with space to move around and drinking water in reach, all was ready to begin by 2:30pm.  Fortunately, there was sufficient cell coverage to let me directly enter an early spot.  Despite the early start, I stayed with my original plan to begin on the 30m band.

Activation

Contacts on 30m came slowly, but I was able to confirm the activation with 11 contacts in just over an hour.  Since the CWT sprint was continuing, I moved over to 17m to see if I could pick up some more distant contacts, but it was not to be.  I heard one strong signal on 17m – calling CQ over me.  I am confident that the operator did not hear me on the frequency, particularly since he did not pick up my call when I responded to his CQ.  Not only that, but my 5 watt signal did not even manage to attract the notice of the RBN.  I took that episode as a sign that it was time to QSY.

Logs from the activation filled up the last 2 pages of one notebook, and the first page of a second notebook.

Since it was past 4pm EDT, and the CWT sprint was finished, I moved over to 20m. Continue reading K3ES’ Hike with Molly: The POTA Dog In-Training! →

Travelogue and Field Report: POTA and Aviation Geekery with Friends in Dayton, Ohio!

3 Comments

A couple months ago, my good friend, Monty, hatched a plan to take his father to the National Museum of the U.S. Air Force in Dayton, Ohio.

I thought it was a brilliant idea. Monty’s dad, John, served in the US Air Force in the 1960s and has always been a fan of aviation. Despite this, he had never been to the USAF museum.

Monty and I have been friends since being roommates back in our undergraduate years; he and his parents are like family to me. (You might remember Monty from a couple of SOTA/POTA activations in the past.)

When Monty asked, “Hey, would you like to join us–?” It took me all of one microsecond to say, “Heck yeah!”

Off we go…

Monty, John, and I hopped in the car and headed to Dayton (from Charlotte, NC) Sunday morning, July 16, 2023.

It was a beautiful day for a 7+ hour road trip, too. Of course, I made sure we timed the trip so that we could stop at Tamarack in Beckley, WV for lunch.

We arrived at our little AirBnB vacation rental late that afternoon.

The house was literally a stone’s throw from the USAF museum. If we would have been any closer, we would have been on the museum driveway.

USAF Museum

Monday morning (July 17) we ate breakfast, then made our way across the road to the museum shortly after they opened the doors at 9:00.

I’ve been to the USAF museum at least fifteen times and it never gets old.

It’s the largest military aviation museum in the world and it’s brilliantly curated. They’re always shuffling around exhibits so that even if you visit annually, you’ll always find something new and fascinating.

The one and only Memphis Belle.

Without a doubt, my favorite part of the museum is the WWII Gallery because I’m such a huge history buff of that era.

Then again, I love the modern stuff, too, and the USAF museum certainly serves it up. Continue reading Travelogue and Field Report: POTA and Aviation Geekery with Friends in Dayton, Ohio! →
