Jersey Shore Vacation POTA-Fest

by Alan (W2AEW)

One of our favorite vacation spots is Long Beach Island (LBI), NJ.  It’s not hard to imagine since my XYL and I are both born & raised in NJ near the shore.  Our late-spring / early-summer vacation was an extended family affair with a few celebrations and long-distance relatives coming to visit the beach rental house on this 18 mile barrier island off the southern coast of New Jersey.

The vacation rental house we stayed in is in the town of Surf City.  It is situated on the bay side of the island, overlooking Manahawkin Bay.

In addition to setting up my Penntek TR-45L and a 40m EFHW at the beach house, I also brought along my POTA kit – complete with the Elecraft KX2 and a small variety of antennas.  The entire island and surrounding area are part of the NJ Coastal Heritage Trail (K-6544).   Two other nearby parks are the Edwin Forsythe Wildlife Management Area (K-0453) and Barnegat Light State Park (K-1609). These latter two parks also fall within the boundaries of the NJ Pinelands Preserve National Conservation Area (K-6609).

My first POTA activation was a simple walk across the street to one of the public benches along the bay shore.  This qualifies as public area within the Trail (K-6544).

The antenna is the SuperAntenna MP1 equipped with a 10’ stainless telescoping whip on top from MFJ.  I used a deep-reach locking clamp to fasten the antenna to the aluminum bulkhead.  The salt-water made a nice counterpoise.  The rest of the setup was resting on the park bench with me.  I only had a limited time to operate, but conditions were pretty favorable and I logged 11 QSOs in 20 minutes on 20m CW running 5W.

The next day, I had another short window to play POTA and planned a short trip to the Edwin Forsythe WMA.  Just as I was heading out of the door, I received a phone call from my nephew that was out running.  He had come across a mother duck and some ducklings that were hanging out near a storm drain.  It turns out that some of the ducklings had fallen through the grate. We tried to lift the grate ourselves and couldn’t.  We called the local police and they arrived a few minutes later.  They called the water department.  Together, we were able to lift the grate, and with 30-40 minutes of coaxing, were able to rescue the trapped duckings from the storm drain and reunite them with the mother.  Needless to say, I didn’t get to the park for the activation.

I was able to finally head out to Cedar Bonnet Island, which is a small island that sits between LBI and the mainland.  This island is part of the Edwin Forsythe WMA, and also lies within the boundaries of the NJ Pinelands Preserve and the NJ Coastal Trail – making it a 3-fer!

Guest Post: A most enjoyable weekend of SOTA and POTA in the Italian Alps!

An enjoyable  weekend

by Simone (IU3QEZ)

I’m part of a Club that promotes QRP activities in the mountains (Mountain QRP Club), in a minimalistic way – small power, small battery, small radio, simple DIY antennas and a lot of friendship.

So what’s better than a full outdoor weekend? Easy peasy, 10 friends together in the Italian alps – Monte Grappa, 1775 meters elevation.

Cars were well packed with QRP gear, tents and sleeping bags. Our place of choice was the nearby area with a mountain hut. We asked for permission to place our tents nearby so even those who are not used to sleeping in tents could participate.

Before starting radio operations we had breakfast. Local salami, cheese and, why not, a  sip of good wine.

You can see here that Riccardo (IU3GKJ) is ready and strengthened from a good breakfast! It’s radio time.

We started with the activation of I-1484 “Massiccio del Grappa”.

To avoid interfering with one another we spread out along  the radio spectrum: from HF to VHF/UHF, magic band included, each of us managed to get contacts on almost every band. Almost everybody was close to getting the 10 QSOs on 10 different bands required by POTA N1CC in just one day.

Guest Post: “It Was Bound To Happen…”

It Was Bound To Happen…

by Matt (W6CSN)

You’d be safe to guess that Mt. Davidson would have been my first SOTA activation seeing as it’s the closest SOTA summit to my home QTH. However, it actually took me a little while to get around to heading up W6/NC-423.

The trail begins near the corner of Dalewood and Lansdale.

Today was the day! I dropped my hiking buddy off at work at 8 AM then drove up Market Street, over Portola Drive and wound my way around Mt. Davidson, finding easy parking on Dalewood Way near Lansdale Ave.

The easy trail up Mt. Davidson.

From the trailhead near the bus stop, it a short and easy hike up to the activation zone. On this route you reach the east end of the summit, opposite the large cross, which is a well known landmark.

Except for the occasional exercise enthusiast, I had the place to myself this morning. Not wanting to lug the fiberglass mast up the hill, I deployed the Gabil Radio tripod and loading coil, using a 3 meter collapsible whip antenna. This is an easy setup and not too much of a compromise on 20 meters.

While I can do a lot of back and forth the get the loading coil set just right for a good match, I find it easier just to get the coil close enough and touch it up with a tuner for a low SWR reading.

I sent a spot via Sotamāt and started calling CQ SOTA on 14.058 using the QCX-Mini. My first call was from JG0AWE from Nagano City, Japan. This was followed quickly by several more stateside calls and I was able to gather the four QSOs needed within a span of five minutes.

QCX-Mini on 20 meters.

I continued working stations and chasing some Summit-to-Summit contacts for another half hour. It was at that point I noticed that I failed to throw the switch to the “Operate” position on the ZM-2 tuner. This whole time I had been operating in “Tune” mode with the 50 ohm absorptive bridge in circuit! It was almost like using a dummy load for an antenna!

Oops! I left the ZM-2 in the “tune” position!

Later, at home, I measured this tuner configuration with this radio using an actual 50 ohm load instead of an antenna and found that I was most likely operating with an effective power to the antenna of only 300 milliwatts!

Despite this extremely low power I was able, using CW, to complete the activation with no difficulty. This is a testament to the effectiveness of the CW mode, and not so much this operators skill.

Sutro Tower and Twin Peaks to the North.

After logging 10 contacts, I called it quits, packed up the station and headed back down for some breakfast. Next time I’ll try to remember to set the switch correctly after tuning up, but I make no promises. I’m guessing pretty much everybody that has a ZM-2 has at one point or other forgot to switch into “operate” mode, It was bound to happen.

KO4WFP: The Final Countdown and an Innovative Solution for My Nova Scotia Trip

The Final Countdown and an Innovative Solution for My Nova Scotia Trip

by Teri (KO4WFP)

As I finalize preparations for my trip to Nova Scotia, during which I plan to activate six or seven parks, I ask myself “How the heck did I get here?” Those of you who read my first field report in this series know that Thomas Witherspoon’s decision to activate parks in Canada last year was my motivation. I admit it is gutsy of a relatively new op to believe I can undertake such a venture.

The necessity of traveling to Nova Scotia by plane drove the decision of what equipment to take. QRP became the name of the game, a great option for a CW op. I purchased the Elecraft KX2, a rig with a great reputation. Once it arrived in early May, I spent the next month and a half acquiring the necessary accessories and skills for this adventure. The final step before I leave is ensuring I have what I need and the room for it. Given others might want to undertake a similar venture, I will share what equipment I have chosen to take and how I am packing it.

I know most people prefer a roll-on suitcase, but after a trip to New York City last summer, I had enough of schlepping wheeled suitcases up and down the many flights of stairs we  traversed. Upon my return to Savannah, I immediately purchased an Osprey Fairview 55 pack. The Fairview pack can be carried as a suitcase by a handle on its side or as a backpack (my preference). As for its size, it meets airline carry-on dimension requirements for domestic flights and has a few points to attach items you might carry if actually using it for hiking. And, best of all, it is made for YLs!

Included with and attached to the front of the pack is a smaller backpack that can be used as a daypack. I figured this would be perfect for most of my ham equipment and proceeded to find a way to fit everything in it. The larger Fairview pack would serve as my carry-on and the smaller daypack as my personal item for the flight.

As you can see, the daypack has a fair amount of room. In the main compartment I have the gorillapod tripod for mounting the AX1 on top of the rental car or a picnic table, the carrying case for Craig, my KX2, and his accompanying items, and two Tom Bihn travel bins. There are two additional compartments inside the daypack – a mesh, zippered pouch and a slot for a laptop or iPad.

When I first began CW POTA activations, I used a notepad to track contacts. However, to save time, I switched to a refurbished laptop with N3FJP loaded to log contacts in real-time. Juggling it and the key didn’t prove as difficult as I originally thought. Also in the laptop slot are documents I don’t want bent like my license (not pictured), band plan, UTC conversion chart, and call sign prefixes for European countries. I am also taking a small steno notepad as a backup for logging contacts as well as making notes for the trip reports I’ll write afterwards.

In the zippered, mesh pocket are the Elecraft manual that came with the rig and my two longer lengths of RG-316, one 25’ and the other 50’. Continue reading KO4WFP: The Final Countdown and an Innovative Solution for My Nova Scotia Trip →

A Nifty Internal Battery Mod for the Elecraft KX1

A Nifty Internal Battery Mod for the Elecraft KX1

by Leo (DL2COM)

I was very happy to learn more about an interesting internal battery solution that came with my recently purchased Elecraft KX1. The original owner, Rolf DF2FK, built this KX1 himself and has a background in electrical engineering. He wanted an internal solution that is safe and delivers the full power output with this transceiver.

elecraft kx-1 internal lipo battery pack
KX1 with custom balanced 4S Lipo battery pack

Disclaimer: Working on custom battery solutions can be very dangerous, esp. with Lipo batteries (possible fire, explosion when handled improperly etc.). Please take safety precautions when attempting to build the following solutions and make sure you stick to the safety instructions of the batteries you work on. Everything happens at your own risk – just like always in Ham Radio 🙂

So he developed an idea around a 4S Lipo pack consisting of 4×3.7V Lipo cells each with a capacity of 820 mAh and each with an own battery management system (BMS). Of course all four are connected in series. The individual BMSs help a great deal in keeping the Lipo cells safe such as avoiding deep discharge, excess charge etc. Continue reading A Nifty Internal Battery Mod for the Elecraft KX1 →

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 →

A New Skill and Antenna Leads to Success at Wormsloe K-3725

A New Skill and Antenna Leads to Success at Wormsloe K-3725

by Teri (KO4WFP)

If you read my field report for Wheeler NWR K-0161, the trap dipole I used vastly outperformed the AX1 that particular day. I originally opted for the AX1 because, for my upcoming trip to Nova Scotia, my family and I will fly so space for ham equipment is limited. But the Wheeler activation convinced me to add an end-fed antenna to my kit for the trip, something several hams recommended. I chose the Tufteln EFRW QRP antenna.

Ham radio has taught me many things, one of them being I tend to procrastinate when I feel intimidated by a project. Case in point – the Pacific Antenna 2040 trap dipole I used in my last activation. My local radio club recommended it for POTA. (They were correct by the way – that antenna works well!) The project sat on my shelf for nine months before I got up the courage to work on it.

The same thing happened when I ordered a Morserino kit. I knew it would be a great learning opportunity due to my limited experience with electronics. Well, it took me three months to get up the courage to tackle that project. So, for whatever reason, getting antennas into trees fell into the same category in my mind. Now, having to use an end-fed antenna for POTA, I needed to learn the skill but had no idea where to begin.

Thankfully Thomas came to the rescue! I found his July 3rd, 2022 post discussing the various iterations of throwing equipment he used and on what he settled. Soon I acquired a Weaver 10 oz. weight, a spool of Marlow 2mm throw line, and a Tom Bihn small travel tray.

I next found Thomas’ Sept. 8th, 2020 post as to how to prepare the line (you tie it to a tree and tug hard on it several times to remove any kinks in the line), flake the line into a cube or bag, tie a slip knot to attach the weight, and then use one of two techniques for launching the line over a branch.

In my HOA, there is a wooded area that offered privacy and the perfect live oak branch, about 15 feet high, for my initial practice session. I opted for what is called the “granny toss”. Heck, if it was good enough for the arborist whose video Thomas featured in his September 8th post, it was good enough for me, no matter how ridiculous it might look. And guess what? Success on the third throw! OK. This skill was not proving to be nearly as daunting as I had assumed.

Now it was time to put this newly-acquired skill to use. Tuesday June 13th, I chose to return to Butter Bean Beach at Wormsloe (K-3725), partially to further my kilo pursuit for this park but also because I knew hams from my local club had used end-fed antennas there.

The drive to Butter Bean Beach from my home is a favorite. I take Ferguson Avenue which has a live oak canopy stretched over the road. The trees are dripping with Spanish moss and look like old Grand Dames swathed in grey boas.

Along the road is Bethesda Academy which used to be an orphanage for boys. The institution was established in 1740 by evangelist George Whitefield. Today Bethesda is a private boarding and day school for boys. The academy has a dairy and I often slow down to look at the cows with their calves in the pastures. You never know what you might see – I’ve actually pulled over to watch a newborn calf take its first steps. (How cool is that!) Today the cows and their calves were lounging in the afternoon shade of one of those Grand Dames. Continue reading A New Skill and Antenna Leads to Success at Wormsloe K-3725 →

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 →

KO4WFP: The Dipole Does It for Wheeler NWR

Many thanks to Teri (KO4WFP) for the following guest post:

The Dipole Does It for Wheeler NWR (K-0161)

by Teri (KO4WFP) 

After my last activation, I was hankering to try the AX1 and Pacific Antenna 2040 trap dipole during the same activation for a comparison. Now, I know some of you are saying, “Well Teri, there would be no contest!” Yes, however, in the interest of learning first-hand, I headed to K-0161, Wheeler National Wildlife Refuge while visiting a friend, Glenn W4YES, and his wife in Decatur, Alabama.

Wheeler National Wildlife Refuge was established in 1938 as a wintering area for ducks, geese, and other migratory birds. It is a 35,000 acre refuge located along the Tennessee River near Decatur, Alabama. Today, the refuge attracts thousands of wintering waterfowl and cranes each year and is a winter home to the endangered whooping crane who first arrived in 2004.

I opted to set up in a parking lot on the north side of US Highway 67 which runs through a small portion of the refuge. As there were no picnic tables present, I chose a spot where the trees would shade me from the early morning sun while sitting in my Subaru Crosstrek. Since the last activation, I had given some thought as to how to set up better in the car. My code buddy Caryn KD2GUT sits in the backseat for POTA with one seat flipped down providing a ready-made table for equipment. Even better, I discovered the back of the rear seat in the Crosstrek has a rubber surface and I could secure the key to it with fun-tak!

Since the last activation, the more I worked with the Mini Palm Paddle, the more I realized I did not like it. It just felt too “squishy” for my taste and I had difficulty feeling the characters. Glenn has a solid state CW paddle by 9A5N he was not using. I worked with it a bit and really liked the stiffer feel. He removed the heavy base in which it was mounted and built a lighter base out of the back of a old diskette so I could take the key with me to Nova Scotia. (True ham radio – making use of whatever we have on hand to solve a problem!) I find the more I use this key, the more I like the feel of it.

This was Glenn’s first POTA activation and I was happy to have him along. We arrived around 8:05 AM and began setting up, first putting the AX1 on the roof of the car and then the trap dipole on a mast on a hitch mount given to me by Jack NW4TF of my local club.

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.
