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

Part 2: N2YCH and K1PCN’s Dayton Hamvention Trip QRP POTA Rove

Part 2: Dayton Hamvention Trip QRP POTA Rove

By Conrad Trautmann, N2YCH

Pennsylvania

Welcome to part two of three of the Hamvention QRP POTA Rove. If you missed part one, you can find that installment here.

Early on Thursday morning, May 18, 2023, Peter, K1PCN and I headed from Morgantown, West Virginia north to Pennsylvania to activate K-8920, the PA 223, Pennsylvania State Game Lands. While the park covered a large geographical area, we were able to find a parking lot not far off the highway that made it easy for us to get to and activate.

Peter spotted a nearby gazebo which was also a viewing area and hiked over to it to activate. If you look closely in the photo below, you can see it in the distance behind the sign and my antenna.  I stayed with the Jeep and set up on the tailgate using the Buddipole vertical.

Since it was early in the day, we used our frequency strategy of Peter on 40 meters and me on 20 meters. My QSO map here shows some decent DX for QRP on 20 meters at 8am ET.

Ohio

We traveled North towards Pittsburgh on Interstate 79 and then West on Interstate 70, passing through West Virginia again and then stopped at K-1934, Barkcamp State Park in Ohio.

I tuned my antenna for 17 meters and Peter activated on 20 meters.

I managed to activate the park, but it was slow going for me on 17, so when Peter finished up on 20, I changed to 20 meters and got a few more on that band just for good measure. Thinking that the slow QSO’s could have been the radio, I did switch to the IC-705 here, but that did not make any difference. It could have been conditions or our location. I did have better luck on 20 meters than 17. And I don’t know about you, but I can never go for just ten QSO’s. I feel like I need a few extra ones just in case. Here is a photo of me set up at a picnic table next to my antenna. Continue reading Part 2: N2YCH and K1PCN’s Dayton Hamvention Trip QRP POTA Rove

Part 1: Dayton Hamvention Trip QRP POTA Rove

By Conrad Trautmann, N2YCH

Peter, K1PCN and I are both avid Parks On The Air activators here in Connecticut and neither of us has ever been to the Dayton Hamvention in Xenia, Ohio. At the urging of others who have attended in the past, we made the decision to attend this year and while we were making the trek out, we wanted to activate parks along the way to add to our activated US states award. We originally planned to activate six states and ended up with one bonus state for a total of seven. This is how things looked before and after the trip.

 

I would like to begin by saying that attending the Hamvention was a great experience. If you have not been to it, I would like to encourage you to attend if you can.

You may have heard about the flea market, the vendor booths, the forum sessions or the food trucks, which are all good, but the best part for me was being in the presence of other hams with similar interests. I struck up conversations and shared stories with many other hams. Everyone was very nice and willing to share their experiences, which is a great way to pick up some good tips.

I am extremely glad I went. If you are on the fence about going, I would recommend you plan to go next year. Oh, and I got to meet this guy in person….

Now on to the rove…

I planned the trip to get as many states as possible. Both Peter and I had already activated CT, NY and NJ, so we did not need to stop in those states as we passed through. I had scoped out some parks near the Delaware and Maryland border, so I looked at those first.

My main criteria on park selection was to pick parks that would be easy-off/easy-on to the main highways we would be traveling to save time on driving. Here is the route map we followed.

We strategized on how we would activate the parks when we got to each one. Peter is an SSB activator, and I am a digital activator. We would not be colliding on the mode of operation. We did need to be on different frequencies though.

In the mornings, Peter took 40 meters and I used 20 meters. Later in the day when the bands opened up, Peter moved up to 20 meters and I bumped up to 17 or 15 meters. Using this strategy, we had no problems getting our minimum ten QSO’s to activate while operating at the same time. Peter also reminded me to bring a handheld and we did park to park QSO’s on 2 meters and 70cm.

As for equipment, I used my Elecraft KX3 transceiver, but I did bring an IC-705 as a backup.

On the first stop in Delaware, I used an Elecraft AX1 antenna but for the rest of the trip I used a Buddipole tripod equipped with a Versa-T with a 17’ MFJ whip tuned to the frequency I was operating on with 50’ cable and an above the ground counterpoise.

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.

A Rock Leads Teri on an Unexpected POTA Activation!

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


A Rock Leads to an Unexpected POTA Activation

by Teri (KO4WFP)

Sticks and stones may break my bones, but a rock can change the trajectory of one’s week.

Monday, while driving to the barn, a rock landed on my windshield leaving a chip in the glass. The soonest and closest appointment was in Bluffton, South Carolina. But having to work the appointment into my week, nixed my planned POTA activation for Wednesday at Wormsloe K-3725. However, I thought to check for any parks near Bluffton and yes, Victoria Bluff Heritage Preserve, K-9197, was within 15 minutes of my appointment. I could fit in an early activation before the appointment and put the AX1 to use for the first time. (Score!)

The drive Tuesday morning from Savannah, Georgia to Bluffton, South Carolina was scenic – lush, green foliage along the road interspersed with salt marsh and freshwater views.

The Victoria Bluff Heritage Preserve is 977 acres and has four miles of easy hiking trails. The warning on the SC Trails website about protective clothing & insect repellent for the large number of ticks that flourish in the preserve’s forest encouraged me to set-up in the parking lot. There were no picnic tables (my usual set-up) present so I planned on operating out of my car, a first for me.

However, how was I to mount the AX1 while sitting in my car since I had no tripod? I was still puzzling over this the morning of the activation when I remembered the Joby Gorillapod stand I purchased last year. Would the tripod mount for the AX1 work with it? Yes! It did.

Activating (sort of) Lake Thunderbird (K-2792) with a homebrew transmitter

Sam Duwe WN5C

When I dove into radio a couple years ago a few sub-hobbies caught my attention: QRP, portable ops, CW, and homebrew. Of course, these all fit nicely together, but in my mind there was a huge leap between soldering an unun and a building a radio. But why not try? What’s the worst that could happen by melting solder and then sitting at a picnic table? This is how I built a simple transmitter and kind of activated a park.

The Michigan Mighty Mite

Nearly everyone has heard about the Michigan Mighty Mite (MMM), a QRPp transmitter popularized by the Solder Smoke blog. There are countless YouTube videos and posts across the internet. It’s very simple: a single transistor, a variable cap, a coil, a crystal and some resistors and a cap. Supposedly one can get up to half a watt of output (I couldn’t). But with a small purchase from Mouser one can oscillate. That seemed pretty cool.

I hadn’t touched an iron until I started playing radio. But I’ve been drawn to homebrew projects. I built a regenerative receiver last year which was very rewarding. I’ve also put together kits (a QCX mini and a TR-35). But my dream has always been to construct a transmitter/receiver combo, or a transceiver. I thought a good place to start was the MMM.

I built the transmitter based on the common schematic for the 40-meter band. The MMM is crystal controlled but I opted to solder in a socket and buy a handful of crystals, so I have the luxury of operating on 7056, 7040, and 7030 kHz. I made a few other improvements, too. The first was to build a low pass filter to attenuate harmonics. Second, although I haven’t finished it yet, the switch on the right will be to choose between multiple crystals. And third, I added a BNC jack to connect a receiver, with a transmit switch. When not in use the transmitter will dump into a dummy load. This receiver switching idea was lifted from the design of the MMM that QRP Guys produces.

When I tested the transmitter at home the best I could get with my charged Bioenno 3 Ah battery was about 300 mW output. The filter is reducing things somewhat, but maybe I need to look into a different transistor or rewind the coil. But I was able to get a 339 signal report from Illinois (no sked) in the midst of distance lightning crashes, so I had a little confidence going forwards. School is out for me this summer, so I decided to head to the park. Continue reading Guest Post: Lake Thunderbird (K-2792) with a homebrew transmitter!

Guest Post: EmComm and FunComm!

Many thanks to Scott (KK4Z) who shares the following post from his blog KK4Z.com:


EmComm and FunComm

by Scott (KK4Z)

As I have said earlier, I practice EmComm to prepare for natural or man-made disasters when normal means of communication fail. FunComm is pretty self-explanatory, it’s things I do for fun. Fun things may include POTA, Field Days (winter and summer), supporting bike rides, and other club activities. I always like it when I can blend the two together. When I participate in POTA either for a weekend camp-out or a day activation, isn’t it kind of a practice run for an EmComm event? I use the same antennas and most of the time the same radios. My equipment gets a good exercise and I learn more about how they operate under different conditions.

Recently, I bought a new camper, the old one wasn’t working well for the things I like to do. The new camper is so much better but not without its growing pains. I had to find a better way to use the radios inside the camper. To save words, here is a picture of what I have been using. It works okay but because it uses part of the bed, it made sleeping uncomfortable. After this last camp out when I woke up all sore and twisted feeling, I decided it was time to find a better way.

The new desk stacks the radio and power supply above the computer. This reduces the overhang on the mattress. The desk area for the paddle does overhang a little but sliding the desk to the right when not in use alleviates that.

The other thing I did was make a cut-out on the door side to make it easier to get my legs out. This works really well and does not impair the stability of the desk.

The last thing is the main desk is 30″ deep and the shelf is 20″ deep. This leaves plenty of room for the radios and enough room to slide the computer under the shelf if I need the desk space for something else.

Sitting behind the desk, the radio controls were easy to get to.

The desk is made from one sheet of 3/4″ plywood with (2) 1×3″x8″ boards. The stain was a can of Minwax I had laying around, I think it was Golden Oak.

Construction was simple, using hand tools found in most garages. It is not a piece of art, I don’t have the time. My philosophy is that “Perfection is the enemy of good enough”. The desk is glued, screwed, and nailed without any fancy joinery. If I waited until I had time to do a better job, the wood would still be at Lowe s.

I tried it out in the driveway and everything works and feels good. The radio is easy to get to and the computer is a little high but not uncomfortable. With the cut-out, it is easy to get in and out of the camper. The next test will be at the end of the month during my next camping trip. Hope to hear you out there. 73 – Scott

Getting To France With Detours: A SOTA/POTA/WWFF Triple Activation

by Thomas (DM1TBE)

As I have written in my activation report for Klínovec, a summit in the Czech Republic, I am trying to activate places outside my home region DM, Germany – Low Mountains in SOTA or DA in POTA. With the May 1st being a public holiday, the long weekend provided a perfect opportunity for an activation a bit further away.

After a while looking around, I chose Brissetish Kopf (FL/VO-126) in France. The summit was close to the German border, hasn’t received much love with only 8 SOTA activations and was also a POTA spot for F-1697 Vosges du Nord Regional Park and WWFF Parc Regional des Vosges du Nord, FFF-0035. That promised enough QSOs for me and provided chances for chasers.

The small cluster to which the arrow points are the Vosges, actually the northern Vosges (Vosges du Nord). The cluster south of it are the higher part of the Vosges. The Vosges are a range of low mountains in Eastern France, which continues as Palatinate Forest on the German side of the border, with the highest summit being 1,424 m / 4,672 ft.

I started my journey quite early, leaving around 8am. During the drive I could not help but had to tease Thomas (K4SWL), who spent quite some time in France and, as far as I know, enjoyed it.

The French region Alsace, through which I had to drive to the Vosges, is quite interesting. The region was disputed over several hundred years between Germany and France and changed back and forth between the two. Many place names are still German, or sometimes a mix of French and German. After the World War II, the region returned to France – hopefully the last change.

I used Google Maps to drive to a parking place close to the summit, but my first attempt ended here:

Not sure why Google meant to show me this – thanks for the 30 minutes detour.

Roughly a half hour later, I arrived at Climbach, the small village next to the summit. Based on findings, the area is populated since the Middle Stone Age, that ranged from 280,000 to 25,000 years ago.

Two SOTA activations in the Swabian Alb – And a broken JPC-7 antenna

by Thomas (DM1TBE)

Intro

I live very close to the Swabian Alb (also known as Swabian Jura or Schwäbische Alb in German). The Swabian Alb is a mountain range in German region Swabia. It ranges from Bavaria in the northeast 200 km / 140 mi to the Swiss border in the southwest.

Thomas Römer, CC BY-SA 3.0, via Wikimedia Commons

The Swabian Alb is a high plateau, which falls slowly to the southeast but with steep cliff-like edges to the northwest. You can follow the northwest edge of the Swabian Alb by looking at the map of the SOTA summits at sotl.as.

The topology limits the possibilities to cross the Swabian Alb, so the course of the routes are more or less unchanged since thousands of years. I live close to an old Roman road. And where an important road was, there isn’t a castle too far away, since the medieval noblemen were quite keen to get its share from passing people and goods.

During the Cold War, important passes received mechanisms to place explosive charges. In case of an advance of the Soviets and its allies, it was planned to blow these roads up, as there was usually no alternative way around.

First Activation: Plettenberg

The Plettenberg (DM/BW-046) is a summit at the edge of the mentioned Swabian Alb, about halfway between Stuttgart and the Swiss border. It’s 1002 m / 3287 ft tall and has a quarry on top.

The quarry uses a ropeway…..

… to transport the stones to the plant.

The way from the parking place to the activation zone was rather short with 300 m /  1000 ft. Continue reading Two SOTA activations in the Swabian Alb – And a broken JPC-7 antenna
