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.

QRP POTA with Friends: Two Park Activations with VE6LK, NJ7V, WD8RIF, and KD8KNC!

4 Comments

Sunday, May 21, 2023, was the final day of Hamvention.

I traveled to Hamvention with my buddies Eric (WD8RIF) and his son Miles (KD8KNC). We decided in advance that instead of attending Hamvention that Sunday (after having spent all day Friday and Saturday there) we’d opt for a relaxing day playing POTA near Dayton/Xenia.

We weren’t, in fact, the only ones who skipped Hamvention that Sunday–our friends Vince (VE6LK or AI7LK State-side) and Charlie (NJ7V) did as well, so we decided to play POTA together!

Both Charlie and Vince were leaving the Dayton area that afternoon, so they needed to finish up their activations by noon at the latest. We decided we could fit in two activations that morning before Charlie and Vince headed back, then Eric, Miles, and I would hit a third park in the afternoon. Actually, Miles never planned to hop on the air, but he was both our ride and valuable POTA support!

Vince and Charlie in the rear view mirror!

Charlie and Vince met us at our hotel around 9:00 AM and we drove to the first of two parks we’d activate together.

Cowan Lake State Park (K-1943)

Charlie (NJ7V) and Vince (VE6LK/AI7LK) ready to deploy their gear.

The weather was beautiful that day, but the space weather, much less so. We knew in advance that it would be a struggle based on the propagation forecast and numerous reports from other activators.

Vince set up his Elecraft KX3-based station in the trunk/boot of his rental car.

He deployed his “low-slung” wire antenna (read more about that here) and hit the air.

Vince’s low-slung antenna

Eric described the POTA station he deployed in his field report on WD8RIF.com:

Eric found a shady, level spot near the parking lot, strapped his 31′ Jackite telescoping fiberglass pole to his folding camp-chair, deployed his 28½’ wire vertical on the pole, set up his Elecraft KX3 on the camp-chair’s flip-up table, and was on the air at 1412 UTC. Eric began his operation with a lovely touch-paddle which he had unexpectedly been given as a gift from the builder, Brian Manley, K3ES. 

Eric’s station

Note that Eric carefully documents each and every one of his field activations and field contests on his website. His field reports date back to Field Day in 1995!

I found a spot to set up next to the lake under the shade of a large tree. I deployed my Tufteln no-transformer 28.5 foot end-fed random wire.  This antenna is simply two lengths of 28.5′ wire: one wire for the radiator and one for the counterpoise. The KX2’s internal ATU does all of the heavy lifting. Continue reading QRP POTA with Friends: Two Park Activations with VE6LK, NJ7V, WD8RIF, and KD8KNC! →

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.

A Rock Leads Teri on an Unexpected POTA Activation!

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.

Mark finds an opportunity to introduce students to the world of POTA and Ham Radio!

Many thanks to Mark (W8EWH) who shares the following field report:

Right Place – Right Time

by Mark (W8EWH)

This is the story of how I was able to introduce about 40 elementary school kids to Ham Radio and more specifically, POTA.  All by just being at the right place at the right time.

I was activating K-1518 (Maybury State Park) on the morning of May 16th while my wife was at the dentist. As I pulled into the parking lot, I saw a yellow school bus (Holy Redeemer), but no kids.  I figured they must be on a hike or already at one of the many shelters.  So, I parked, grabbed my gear, and walked to the spot where I wanted to activate.  This is a spot I’ve used before – a picnic table under several tall, mature trees with great branches for hoisting a wire antenna.  The location is on the top of a rise at the far end of an open field surrounded by forest. Turns out the shelter at the near end is where the students were, busy with whatever the teachers had them doing.  My activation spot seemed available, so I walked back to it staying well clear of the class.

Set up was straight forward (KX3 and EFHW) and I was quickly on the air on 40M.  Band conditions were good, and I quickly had my 10 contacts to make the activation.  After about 20 contacts there was a break in the action, so I switched to 20M and decided to speak to one of the teachers which, while I was activating, had brought a group of about a dozen students to my end of the field for some sort of activity.  I waived to her and introduced myself, first asking if I was in their way.  She said no, and asked if she was in my way.  Of course not.  I explained what I was doing and offered a demonstration if she wanted to bring some or all the kids over.  She enthusiastically agreed to this.

So about 10 minutes later, the teachers brought the class over to me.  I had them stand behind me in a way that kept them from getting tangled in the antenna and coax.  I introduced myself and explained that I was an amateur radio operator using a portable radio and antenna to contact other people like me as part of an activity called Parks on the Air.

In this case I said, I’m set up here in this state park which makes me the “activator”, and everyone else the “hunters”.  They thought that was funny.  I then told them about the contacts I’d already made to various states around Michigan, and this seemed to get their attention.  I then explained that I was not speaking with them, but instead using Morse Code.  They all seemed to have heard of this before.  OK I said, I’m going to unplug my earbuds, turn up the speaker, and let’s see if we can make a couple contacts.

Before I started calling CQ POTA, I explained what I was going to be sending in morse code.  That I was letting anyone listening know that I was operating from a park, so please call me, and here is my call sign – my amateur radio name.  I also warned them that just like when you go fishing, you don’t catch a fish with every cast.  You must be patient.  They understood.  I was nervous – I’ve never had an audience like this before.  But then I thought, they won’t know if I make a mistake!

It took about 5 or 6 CQ’s before I got bite.  Yes, I was starting to get a little worried!  But then we had a catch and after I finished the back and forth of the contact I said – that was Georgia – and was greeted with a cheer.  Another I said?  Yes!  I sent another CQ and right away another bite.  The kids listened to the back and forth and then I said – Kansas!  Another cheer.

I this point I answered a couple of questions (including one about how I was it that I could understand the noises they were hearing) and then the teachers called an end to the demo so that they could start a nature hike.

I finished up the activation with a handful of additional contacts on 20, 30, and 17 meters, then called it a day.  See Figure 1.  My wife was on her way home from the dentist and she would stop by so we could go for a hike before going home.

I’m so glad I had the opportunity to conduct this demonstration.  I’ll never forget it.  I hope a least a couple of the kids will remember this and become hams in the future.  I only wish I had a handout or two that I could have given the teachers so if they wanted to explore amateur radio with the class later, they’d have some background info and links.  I’ll be ready next time.

Figure 1.  QSO Map for POTA activation of K-1518, via HAMRS..  The contact in Idaho was my one and only on 15M.

POTA QRP: Testing the new JNCRadio CS-818 ATU with my upgraded Yaesu FT-818ND

2 Comments

I love testing new stuff in the field and on Tuesday, May 2, 2023 I had a great opportunity to test a number of new items.

FT-818ND Upgrades

I mentioned in a previous post that I purchased a new Yaesu FT-818ND from DX Engineering on December 28, 2022. It smacked of an impulse purchase only in that I had not planned to purchase the radio that very day.

Thing is, Yaesu announced they were discontinuing the FT-818 and I always planned to purchase one to replace out one of my two FT-817NDs. I didn’t want to miss the opportunity to buy a new one under warranty, so I bit the bullet on short notice.

Within a few days of purchasing the FT-818ND, I also purchased another 500 kHz CW filter, a WINDCAMP 3000mAh LIPO battery and a WINDCAMP Anderson PowerPole Adapter.

I planned to make the FT-818ND my primary HF radio and use the other FT-817(s) for full duplex satellite work (and HF too, of course, especially since one is now in a TPA-817 pack frame).

I had all of the upgrades in hand by mid-February, but that Yaesu FT-818ND sat in its box under my radio bench until late April. I was so busy evaluating other gear and keeping up with my busy family life,  it had almost slipped my mind. Well, that and I received the incorrect narrow Collins filter from a seller on eBay; instead of sourcing a replacement, I decided to steal an original 500 Hz filter from one of my other radios while waiting on a replacement.

Those narrow Collins filters? They’ve become pure unobtainium over the past couple of months. At one point, eBay was chock full of them. No longer…

It had actually been a very long time since I pulled out a brand new (non-loaner) radio from the box. It’s funny because I remember opening my first FT-817 back in…what…2001? The box and packaging were identical some twenty one years later!

I unboxed then immediately opened the chassis of the FT-818ND to add the Collins filter, attach my Portable Zero side rails (stolen from my FT-817), add the Windcamp battery pack, and add the Windcamp Anderson PP adapter.

JNCRadio CS-818 ATU

Around the same time, Jesse, with Chelegance, also sent me his latest ATU: the CS-818 which is specifically designed to work with the FT-817 and FT-818 series radios. To be clear, Jesse sent the MC-818 at no cost to me to evaluate.

The CS-818 actually works with any radio, but it ships with the command cable for the FT-817/818 for full integration.

The CS-818 can handle up to 30 watts of power, so it’ll pair nicely with any QRP radio. If using it with a QRO radio, you’d have to be very careful not to push more than 30 watts.

NOTE: Due to the frame rate of my camera and the refresh rate of the OLED display, only a portion of the display shows up in my shots.

In truth, ATUs don’t get me terribly excited. I’m quite content with my Elecraft T1 and Emtech ZM-2; these two portable ATUs match anything and everything I use in the field. Continue reading POTA QRP: Testing the new JNCRadio CS-818 ATU with my upgraded Yaesu FT-818ND →

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.

Guest Post: Lake Thunderbird (K-2792) with a homebrew transmitter!

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! →

SOTA on Hibriten Mountain: Testing my new backpack and working a little QRP DX!

5 Comments

On Friday, April 28, 2023, the clouds lifted and I was eager to fit in a brisk hike.

We’d had a few days of wet weather and, in fact, the previous day I performed a POTA activation with my entire station and antenna under the roof of a picnic shelter.

I was visiting my parents and didn’t want to venture too far afield, but still wanted to fit in a good summit activation. The goal was to stretch my legs and to test my Mystery Ranch Scree 32 backpack. Before taking this pack on a difficult summit hike, I thought it might make sense to check the pack’s suspension and fit with it loaded down a bit heavier than I normally would.

This would actually be my second SOTA activation with the Scree 32 pack (here’s the first) but on that first hike, the pack was so light, I barely noticed it was on my back.

Hibriten Mountain (W4C/EM-093)

Hibriten was an easy choice for the day. It’s only a 25 minute drive from my parents’ home and the trail has modest elevation change over the 5.6 mile round trip hike.

The trail is basically a wide, gravel access road for the crews who maintain the communication towers on Hibriten’s summit.

I remembered from my previous activation of Hibriten that the hike was very pleasant.

It certainly was that Friday!

It wasn’t a terribly hot day, but it was very humid as the sun burned off all of the rain we’d received over previous days.

I hiked at a brisk clip to make the most of my workout and, if I’m being honest, I was pretty darn happy to see the summit. Continue reading SOTA on Hibriten Mountain: Testing my new backpack and working a little QRP DX! →

Pit Stop Style Activation with Elecraft KX3 and AX1

10 Comments

(As is my usual, this article has a bunch of links – click on as many as you wish to receive the full experience)

by Vince (VE6LK)

In May of 2023 I embarked on a two week vacation to Hamilton Ontario, the city of Waterfalls. And I found myself with a spare 30 minutes so I decided to squeeze in an activation.

And as I am an opportunist, I made this decision at 23:25’ish z and I had not yet arrived at the park but the target was only a few minutes away! I would have until 23:59:59z to complete it if I were to be successful. “It’s time to break out the Elecraft AX1 antenna I bought at Hamvention last week“ I think to myself. It would be my first time using the antenna. I had pre-read the instructions and knew what had to be done in order to set it up.

The whole thing would unfold like a Formula 1 pit stop, albeit a wee bit slower <grin>.

Battlefield House

I arrived at VE-5351, The Battle of Stoney Creek National Historic Site and began to scout a location. Pausing only long enough to snap a few photos, I parked and immediately got to work. Continue reading Pit Stop Style Activation with Elecraft KX3 and AX1 →
