Poland Adventures – Part II

After completing my first POTA Rove, it was time to look for other opportunities. The next day, we planned a trip close to the border between Poland and Germany. Due to the high density of POTA parks in Poland, it was not too hard to find a POTA park for me.

The park Łęgi koło Słubic Nature Reserve (SP-1908) is a floodplain for the Oder River, the border river between Poland and Germany. As described in my previous post, the border was shifted from further east to the Oder river as part of the territorial changes at the end of World War II. Later, Poland was the only country, along with Czechoslovakia, where people from East Germany, i.e., the Soviet-controlled part of Germany, could travel to without permission. This arrangement came to an end in 1980 with the rise of the Solidarność (Solidarity) movement in Poland, a social movement against the pro-Soviet government, and the subsequent declaration of martial law.

After the reunification of Germany in 1990, the border became a kind of ‘wealth border’ between Eastern and Western Europe, giving rise to various issues such as crime and immigration. Following Poland’s accession to the European Union in 2004 and its entry into the Schengen Area in 2007, which involved the removal of all border controls, the situation improved. Now the only thing indicating a border ahead is the black-red-yellow post.

The current rapid pace of development in Poland does not make it impossible to overtake Germany in the foreseeable future.

Back to the activation. I took the following equipment with me:

When going (as in walking) to an unknown park without knowing the circumstances, I like to have the option to choose between an antenna with a small and a large footprint. So far, I have just made a handful of car-based activations. But I increasingly like it as it opens another world with big antennas and bigger rigs. We recently made a test activation with an Icom IC-7300 and a 6-band Cobweb antenna from AWK, by chance also from Poland.

But that’s another story.

Not sure if I have mentioned it: My BaMaKey had a technical issue and I had to send it back to the manufacturer. The repair took just a couple of days and the communication was very smooth and convenient. I was happy to have my favourite key back in time before my vacation.

So after I dropped my family to do their business, I went on and looked around for a nice place. Of course, I had to see the actual border.

Left Poland, right Germany. In the background is Frankfurt (Oder), not to be confused with the more well-known Frankfurt am Main.

The weather looked a bit difficult, but it remained dry.

Eventually, I found a place in a meadow with more than enough space for the SOTABeams linked dipole so I could leave the JPC-12, the ground mounted vertical, in the backpack. In the meanwhile, I am used to the SOTABeams antenna. I can build it alone in less than 5 minutes and – as it is hard to beat a dipole – have a very good antenna for operating QRP.

The activation was difficult. It was a holiday season, a morning during a weekday, and the conditions were tough. After 30 minutes, I had just 4 QSOs. So I asked in the chat groups of my local ham radio club and a German POTA group for help. After 1.5 hours, I ended the activation with 15 QSOs, of which 5 were from the alerted groups. At least the place was nice, and the weather was not as hot as in the days before.

The next day, I wanted to spend some time with my 7-year-old son, and I was looking for an opportunity to combine it with a quick activation. I remembered the bunkers and museums of the Ostwall (East Wall), technically Festungsfront Oder-Warthe-Bogen (Fortified Front Oder-Warthe-Bogen). The structure, spanning 120 km / 75 miles in total, was constructed between 1934 and 1944. It stood as the most technologically advanced fortification system during the era of Nazi Germany, and continues to be one of the largest systems of its kind in the world today.

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 →

New POTA Location: From Proposal to Activation at Lightspeed

4 Comments

by Thomas (DM1TBE)

If you followed my activation reports, you may (or may not) remember that I have just started pursuing POTA this year with the program gaining popularity in Europe and hence resulting in sufficient chasers for activations. However, the number of parks is not that high in Germany when compared to other countries. So the local POTA admins asked to submit proposals to fill the gaps across Germany.

Last Friday, I was browsing through the area I live in and thought about areas that would suit POTA. I stumbled upon Spielburg. The upper part of the SOTA summit Hohenstaufen, which I have visited and written a report about earlier this year, was once higher, but about two million years ago, slid down and formed the present-day Spielburg.

Not much of it remains today, as it was used as a quarry until the 1950s. Today it is a protected nature area of 31 ha / 77 acres consisting of a unique biotope with distinctive white Jura limestone cliffs. Although not large, it is popular among the locals for hiking, as a viewing point, and – as I have spotted during my visit – a place for romantic picnics.

So I suggested the area to the local POTA admins on a Friday afternoon. The following day, late in the evening, I received an email from local POTA admin Heinrich, DO1HFS, telling me that my proposal has been accepted as DA-0514. What a great response time – Vielen Dank, Heinrich.

I have been there a couple of times without a radio but with family and kids, but I did not pay attention to possible locations for an activation. I checked some online maps and imagery, but it did not help me much further. So I took the SOTAbeams Band Hopper III and the vertical JPC-12 with me to be prepared for larger and smaller possibilities. I also want to have at least 36 QSOs after 7pm local time to complete my POTA Late Shift Activator award. Therefore, I thought using FT8, which I have never used before during an activation, would make it easier to achieve such a number.

So the following Sunday, I started the activation. This one and all my previous activations were “backpack” activations, i.e., all my equipment fitted into a backpack, and I walked at least the last meters, usually over a mile, carrying all the stuff. In this case, my place for the activation was just 1 km / 0.6 mi away from parking, but I walked through the whole area to find the best place. Eventually, I found a wooden bench with a nice view and a meadow behind, where there was sufficient space for the SOTAbeams Bandhopper linked dipole for the 20, 30, and 40-meter bands.

The equipment I used consisted of

plus some other utilities such as a Surface Laptop for WSJT-X, the PAC-12 vertical antenna, which I have not used, pen & paper… Continue reading New POTA Location: From Proposal to Activation at Lightspeed →

The Beauty and the Boring: Two SOTA Summits in Southern Germany

As you probably know, SOTA, unlike POTA, provides little to no motivation to activate a place more than once during a calendar year. However, I still activate nearby summits multiple times because I enjoy the location and the activity, even though the activations, or better the points are greyed out.

Therefore, as the calendar year progresses, the travel time to reach a SOTA mountain keeps increasing. When the travel time exceeds one hour one-way, I typically try to schedule two activations on the same day. This is what I did last weekend.

SUMMIT IPF

My first summit was called Ipf (DM/BW-131). The Ipf is a treeless free standing mountain with an elevation of 668 metres / 2,192 ft. At its peak, there is a prehistoric hill fort.

The flattened top of about 180 m / 590 ft shows evidence of settlement and fortification spanning almost a thousand years from 1200 BC – 300 BC. During its existence, the “princely seat” served as an important regional center of power and aristocratic residence with trade connections to Greece and Italy.

The oval summit plateau was once surrounded by a perimeter wall, which supported a wooden-reinforced wall about 5 m / 16ft wide. There is an information center at the foot of the mountain, where a part of the wall has been reconstructed.

On the flat eastern side, there is an additional intermediate wall trench that extends about 150 m / 490 ft from the main wall. Approximately 60 m / 197 ft to the east, a third fortified line features a wooden-reinforced stone wall. Below the summit plateau by 50-60 m / 164-197 ft, a fourth wall surrounds the south, east, and north sides, shielded by steep slopes on the west. This wall, along with a trench, extends northward to the mountain’s base, safeguarding three preserved well shafts. The ancient castle entrance led from the southeast to the elevated plateau. The old path remains the easiest route, providing scenic views of the trench system. Continue reading The Beauty and the Boring: Two SOTA Summits in Southern Germany →

On Top of Germany: Activating the Highest Mountain with my KX3 and the PAC-12

9 Comments

by Thomas (DM1TBE)

During the past couple of months, I stumbled upon two or three documentaries about the mountain Zugspitze and the surrounding area. One day I thought, what it is that is preventing me from activating the Zugspitze (DL/WS-001) for the SOTA-program? The answer was rather short: a 3-hour drive. So, I waited for a good opportunity and accepted the challenge on a sunny and warm Saturday in June.

The Zugspitze, with an elevation of 2,962 m / 9,718 ft, is the highest peak in Germany and I think it is fair to say that it is also one of Europe’s highest mountains. Located in the Bavarian Alps near the German-Austrian border, the Zugspitze offers breathtaking panoramic views of the surrounding mountain ranges and picturesque landscapes. It is a popular destination for outdoor enthusiasts, attracting hikers, climbers, skiers, and snowboarders throughout the year. The Zugspitze is accessible via cogwheel train, cable car, and hiking trails. At the platforms on the summit, visitors can enjoy a range of facilities, including observation platforms, restaurants, a simple accommodation option, which specifically caters to hikers, and the international border between Austria and Germany across the platforms.

The lake in front of the mountain is called Eibsee. With its crystal-clear, but ice-cold waters, the lake is a popular destination for swimming, boating, and other water activities during the summer months.

Surrounded by majestic mountains and dense forests, like in a fairy tale, the Eibsee offers a picturesque and tranquil setting.

I started early in the morning on a nice Saturday. I must admit that a 3-hour drive for a SOTA summit might sound a bit extreme, but this is a special mountain for me, I have never been even close to such a high altitude – except in a plane. If you have ever been in the Alps, you probably remember the typical residential buildings that you see all around.

I arrived late in the morning at a parking place that is next to the cable car station.

Before going to the summit, I wanted to walk around the lake Eibsee. The hike around the lake is 7 km / 4.4 mi but took it longer than expected. The tour provides numerous opportunities to make incredible pictures.

Although I am a photographic noob and make pictures with the camera default settings, I quite like the results – all picture of this blog post are taken by me. Continue reading On Top of Germany: Activating the Highest Mountain with my KX3 and the PAC-12 →

Exploring History and POTA: My Second SOTAbeams Bandhopper III Adventure

2 Comments

by Thomas (DM1TBE)

As I mentioned in my recent activation report, I was very impressed with the SOTAbeams Bandhopper III antenna and was eager to test it again. While browsing through the maps of WWFF, SOTA, and POTA, I stumbled upon a new, unactivated POTA park that was not too far from my location – the Bucher Stausee Recreation Site (DA-0414). In the immediate vicinity of the new park, there are several archaeological sites containing the ruins of approximately 2000-year-old Roman buildings.

If you are not interested in the history part, just skip to the Activation section.

The world in Europe was relatively straightforward after 0 AD. From a political, military, and economic standpoint, there was the Roman Empire and then there was everything else.

The following map illustrates the Roman Empire at its greatest extent and the location of the Roman province of Raetia, which encompasses present-day southern Germany and parts of Switzerland and Austria—the very region where I live and where the park is located. This region shared borders with the former territories of Germanic tribes.

To the northeast, a wall called the “Limes” was constructed to separate from the unconquered territory of Germanic tribes. The Limes was a fortified border system of the Roman Empire, primarily constructed during the 1st and 2nd centuries AD. It served as a defensive line, marking the outer boundary of the Roman territories.

Interestingly, the Limes passed nearly through the POTA activation zone, adding a historical significance to the area.

One, maybe the main reason why the Roman Empire ceased further conquests in Germania and constructed defensive positions was the Battle of Teutoburg Forest.

The Battle of Teutoburg Forest, occurring in 9 AD, was a significant event in the Roman history. It resulted in a major defeat for the Roman Empire against an alliance of Germanic tribes led by Arminius. The battle led to the loss of three Roman legions, which constituted approximately an eighth of the entire Roman army. This defeat served as a turning point, prompting the Romans to recognize the challenges of conquering Germanic territories and shifting their strategy towards defense by constructing fortifications like the Limes.

Therefore, my journey began by visiting the ruins of a Castra, a Roman fort. The fort housed an infantry unit with a cavalry attachment, consisting of around 500 soldiers. The fort and neighboring civilian structures were eventually abandoned around 260 AD with the withdrawal of the Romans from this region.

The fort had a size of 140 m x 150 m / 460 ft x 490 ft. On an information panel, a reconstruction is displayed.

I walked around the perimeter and thought about the histories that this place could be telling me. Then I proceeded to visit the civilian structures. Continue reading Exploring History and POTA: My Second SOTAbeams Bandhopper III Adventure →

Quick test of my new SOTAbeams Band Hopper III antenna at a POTA/SOTA location

7 Comments

by Thomas (DM1TBE)

Since I have seen the Band Hopper III antenna at the website of SOTAbeams, I have been thinking about it. Most of the time I have used end-fed half-wave (EFHW) antennas when operating portable – vertical attached to a fiberglass mast or in a sloper configuration with a tree.  Those EFHW antennas seemed to cause way less troubles than a dipole with its centerpiece and coax at the thin end of the fiberglass mast.  However, there was this “other” dipole from SOTAbeams. So I thought I could give it a try and ordered it.

Two days later -including customs procedure- the antenna arrived. The antenna is a linked dipole for the 20-, 30- and 40-meter band and weights less than 500 g / 18 oz. That includes the coax and guying material. I already had the Tactical Mini ultra, a 6 m / 19.6 ft fiberglass mast that is a perfect fit for the Band Hopper antenna.

The weather was fine, my manager at work was on vacation, so there was no reason for not leaving the home office early and go for a quick activation. I went to the SOTA location for Kaltes Feld (DM/BW-659), which is also POTA (DA-0410). I have been there a couple of times this year, but offering chaser points for both programs promised more QSOs, especially when conditions are difficult. The other advantage of this place is that you can drink cold beer if the antenna fails to work. 😉

You may, or more likely may not, remember this image from an activation report in March this year.

The place looks much more inviting now with kids playing, people enjoying barbecue and a cold beer, and operating a radio is much more pleasant.

Although I have been here a couple of times, I have never visited the ruins of Castle Granegg, just a mile away. While the SOTA activation zone is surrounded by trees, the walk to the castle satisfies with a nice viewpoint on the way.

My One Day Mini-DXpedition to Switzerland

8 Comments
View from the Swiss Radegg castle over the valley towards Germany

My wife and kids were with her parents for some days, the weather forecast 25° C / 77° F and the following Monday was a public holiday in Germany – perfect condition for an activation day trip during the weekend. With France and the Czech Republic already visited this year, there were two other neighbor countries waiting to be visited: Switzerland and Austria (the one without kangaroos).  Austria is on my schedule for the Ham Radio fair in Friedrichshafen, so it became Switzerland.

The area northwest of the Swiss town Schaffhausen was perfect.

The region has been inhabited for more than 10,000 years.  Schaffhausen started as an independent city-state around 1000 AD and became a Canton later. A canton is a type of administrative division similar to a state, but in European dimensions. The Swiss Confederation, as a whole, is smaller in size compared to West Virginia and has a slightly smaller population than New Jersey. Anyways, in 1330, the town lost all its lands and its independence, but regained its independence back in 1418. Schaffhausen joined the Swiss Confederation as the twelfth member in 1501. In 1944, Schaffhausen experienced a bombing raid by aircrafts from the US Air Forces, which misidentified the town in the neutral Switzerland as their target Ludwigshafen in Nazi-Germany.

The region is not too far from my home, it has a SOTA summit, which is in a POTA and WWFF area, is history-rich and has a second, although German, SOTA summit not too far away.

I started early on that Sunday morning at 8 a.m. The autobahn was nearly empty and just like an invitation to drive a bit faster. Since Corona, I haven’t been using my car very often, so I still had winter tires on, which are limited to 160 kmh / 100 mph.

Since 2008, Switzerland is in the European Schengen Area, so there are no regular border checks. Even before, it was a so-called “Green Border”, i.e. you could often pass it without checks. Without this old, unused border station, you would barely notice that you have crossed the line.

Some minutes later I approached the area, where the first summit is located.

The Wannenberg / Wannebärg (HB/SH-002) is a wooded mountain with an elevation of 661 m / 2168 ft. The peak is rather flat and also wooded. The way from the parking place at the foot of the mountain to the top is rather short and easy, with 2.1 km / 1.3 mi and an ascent of 140 m / 460 ft.

Park and Castle activation at the medieval Helfenstein castle

7 Comments

by Thomas (DM1TBE)

The last weekend was too rainy to operate outdoors. So I welcomed the public holiday on Thursday, which allowed me to take a day off on Friday and have four days off. We call such days “Bridge Day” in Germany, they “bridge” a public holiday to the weekend.

Some time ago, I have suggested a new protected area to the WWFF, the World Wide Flora and Fauna program. The nature reserve Eybtal covers an area of over 1331 hectares / 3300 acres and is the largest nature reserve in the Stuttgart administrative district. The nature reserve is on the edge of the Swabian Alb, and the ruins of the medieval castle Helfenstein are well within the WWFF activation zone.

The Helfenstein Castle is a historic fortress can be traced back to around 1100 AD when it was constructed as a strategic stronghold to protect the surrounding territories.

Coat of Arms

During the 13th and 14th century it was the seat of the Earls of Helfenstein. After a lost battle in 1372 things went south and in 1396 the family of Helfenstein had to sell a large part of its territory, including its family seat.

The new owners expanded the castle into a formidable fortress. They extended the castle walls to include a fortified tower and a second ring of walls.

Around the year 1400, a tower was built on the nearby rock. It served as a lookout and was intended to prevent the castle from being cannon-fired from that location.

During the Second Margrave War in the 16th century, Helfenstein Castle was besieged and heavily damaged. It was subsequently abandoned and fell into ruins.  In the 19th century, there was a renewed interest in medieval architecture, and efforts were made to preserve and restore Helfenstein Castle. The ruins were partially reconstructed, and today, visitors can explore the restored sections. Continue reading Park and Castle activation at the medieval Helfenstein castle →

A Triple activation and why I switched from a KX3 to Icom’s IC-705

25 Comments

by Thomas (DM1TBE)

Intro

The last weekend was pretty nice and just like an invitation to operate outdoors. As I wrote in one of my previous posts, I often activate summits on the Swabian Alp, a high plateau, which falls with steep cliff-like edges and many SOTA summits to the northwest. If you approach it from the foothills where I live, the sharp edge is clearly visible.

On the way to the ascent, you came along old, picturesque villages. If you look closely, you can see the “Maibaum”.

The tradition of erecting a “Maibaum” (Maypole) is a long-standing custom in Germany, particularly in the southern regions. The Maibaum is a tall wooden pole that is decorated with colorful ribbons, wreaths, and symbols of the local community. It is usually erected on May Day or the night before and is a symbol of spring, fertility, and community spirit. In some regions, it is also accompanied by folk dances, music, and festivities.

It was my third activation of the summit Römerstein, and every time I used another transceiver.

My transceiver history

When I started with ham radio, I used an old Icom IC-706.

The lack of modern features such as DSP and filters, and the current consumption made it not the first choice for portable operators. I soon switched to an Icom IC-7300 at home and got used to a waterfall and spectrum display.  After two activations with the 706 I bought a Xiegu G90.

During the time of my first activation of the Römerstein, I operated only in SSB. So, I was happy with the G90. The display was small, but way better than my old 706. I was satisfied and used the G90 until I started with CW. In CW, I prefer using headphones until today. The sound of the G90 was uncomfortable for me. The lowest volume was too loud, a lot of loud cracks annoyed me, and I was never happy with the filters. Continue reading A Triple activation and why I switched from a KX3 to Icom’s IC-705 →
