I am a very, very new CW operator! I’m also an airline pilot who travels quite a bit. Many times when I’m out flying my company provided hotel rooms are within walking distance of POTA parks.

The MTR-4B is my travel radio. It lives in my suitcase nestled in a Magpul DAKA Utility Organizer pouch.

The DAKA pouch holds:

Everything has to fit nicely in my 22″ roller board.

As flight crew, our roller boards are typically from Luggage Works or StrongBags. I have found that I can always make room for more radio gear in my luggage by packing less undergarments. I mean, you can always make your underwear and socks last another 24 hours by turning them inside out for another wear. Lol

The SOTA beams Tactical Mini Mast fits diagonally in my 22″ roller board. Wrapped around it are some rubber coated heavy wire for securing it to a post/shrub if available.

The SOTAbeams Band Hopper III is my go to antenna. This antenna does it all!

  • rated 125W
  • it’s a a full size half wave dipole
  • with 33ft RG174 coax
  • guying system
  • resonant on (20m 30m 40m) no tuner needed
  • has a balun
  • only weighs 14oz

The wire/guying winders are awesome. I have used this system in the sand on a beach and on a mountain top above the tree line. I replaced the aluminum tent pegs with some plastic ones to keep TSA a bit more happy with me.

I use a Talent cell battery [affiliate link] everyday for a recharge while on the go. It is large enough to power my cell phone/iPad while also powering my MTR, and the voltage output is safe for the MTR to handle.

My CW skills are not yet to the point that I am able to activate a park by running a pile up, so I do a lot of hunting. If one day you have me in you log book from California and the very next day I’m sending from Massachusetts that’s not a mistake, that’s just my life. 73!

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

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

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 →
