The joy of a low-slung wire

(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 that co-incidentally happened to include a side trip to Hamvention just outside of Dayton, Ohio.

For a guy living in Alberta, Canada, this would prove to be quite the trip and it created memories to last a lifetime. I also was told that I could play radio during the trip provided my wife would get to see some of the many waterfalls in the City of Hamilton, the area we’d call home for our two week trip.

At Niagara Falls

Yes, I did take a brief detour to Niagara Falls while on the trip as it is only an hour from Hamilton.

And thus the planning began. I started overlaying POTA entities that overlapped on waterfalls so we both could visit and enjoy in our own way. It also meant I had to figure out what radio gear and, most importantly antennas, to bring along.

I landed up mostly running with low-slung antennas. By this I mean something between 4 and 10′ off the ground and horizontal in orientation. But it’s what I discovered about this simple approach that made it appear like pure magic to me – I made great contacts at what I would consider to be beyond NVIS distances including one from OH to UT!

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

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!

A YL + KX2 = QRP POTA Fun!

A YL + KX2 = QRP POTA Fun

by Teri (KO4WFP)

Last year, I read about Thomas K4SWL’s trip to Canada and plan to activate while there and thought to myself, “Wow! Wouldn’t it be cool to do that one day?” Well, it so happens that my family decided our 2023 summer trip will be to Nova Scotia and immediately I began thinking of how I could work POTA activations into the trip.

Due to time limitations, we are opting to fly which means my Yaesu FT-891 will not work. As much as I have come to enjoy using this radio, it is too bulky and heavy for airplane travel. So I started looking into QRP setups.

I chose the Elecraft KX2 and AX1. Whenever I mentioned to someone I had ordered the KX2, the immediate response was “You’ll love it!” I wasn’t sure it would arrive before the trip, though, given Elecraft’s order fulfillment estimation of 12 to 16 weeks. (Yikes!) Thankfully, the rig and antenna arrived early May giving me six weeks to familiarize myself with the rig and antenna before my summer trip.

So this past Wednesday May 17th, the KX2 and I headed to Wormsloe State Historic Site (K-3725) for my first POTA QRP activation. Quirky note: I’ve actually named the KX2 “Craig”. I figure it and I will be spending lots of time with each other so we might as well be on a first-name basis! Continue reading A YL + KX2 = QRP POTA Fun!

Rainy Day POTA: Setting up the Chelegance MC-750 Vertical Antenna Inside a Picnic Shelter?

On Thursday, April 27, 2023, it was pouring rain, so the perfect time for a little POTA, right–?

Right!

Actually, I had an idea: in the past, I’ve been known to play POTA under the roof of a picnic shelter on rainy days. I’ve even been known to use my AX1 antenna inside the shelter, under a metal roof. Quite a few times, actually.

Of course, it’s not optimal to operate with your antenna under a metal roof, but with POTA? Let’s just say that you can get away with a lot of less-than-optimal antenna deployments.

That’s the benefit of being the DX!

The MC-750 Tripod

An in-the-shelter activation was also the perfect opportunity to test the new Chelegance tripod that fits both the MC-750 and the JPC-12.

A number of readers have reached out asking about this tripod, so when Jesse at Chelegance asked if I’d like to test it, I agreed to do so.

To be clear, he sent this to me at no cost for evaluation. It’s actually quite affordable ($30 on the Chelegance website, $40 at DX Engineering, for example) so purchasing it would have been easy enough, but Jesse also wanted me to evaluate their new FT-818 ATU, so he sent both at the same time (you’ll see the ATU in a future field report).

The tripod feels very sturdy and is simple to deploy. It’s also a little heavy, so keep that in mind if you plan to pack it in for a long SOTA hike.

A number of you have purchased this tripod and have only had positive comments. I now see why.

I speak about this in more detail in the activation video below.

Lake Norman State Park (K-2740)

I decided that it had been too long since I had activated Lake Norman State Park, so I hopped in the car and headed to Troutman, NC! Lake Norman has a number of picnic shelters and covered areas thus a very safe bet.

It was a rainy day so, of course, I pulled into the Lake Norman picnic area only to find one other car there. In fact, by the time I had taken my backpack to the picnic shelter, that other park visitor appeared at a trailhead, hopped in her car, and left.

The picnic shelter sign wasn’t set to “reserved” either, so it looked like I had a green light to claim it for POTA! Continue reading Rainy Day POTA: Setting up the Chelegance MC-750 Vertical Antenna Inside a Picnic Shelter?

Park and Castle activation at the medieval Helfenstein castle

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

Postcard Field Report: Pairing the Elecraft KX2 and MM0OPX EFHW to face dubious propagation

Welcome to another Postcard Field Report!

I’m still in Dayton after Hamvention weekend, but didn’t want to skip my field report and activation video, so a hope you enjoy the slightly shorter report below:

Zebulon Vance Historic Birthplace (K-6856)

On Tuesday, April 25, 2023, I once again stopped by my weekly POTA spot, the Vance Birthplace.  By mid-May, I will no longer be passing by this excellent little POTA site on a weekly basis, so my activations here will be much less frequent. A shame because I do love this site and its staff!

For this particular activation, I’d planned to test my almost perfectly trimmed QRPguys Tunable EFHW antenna, but I left it at home. Not a problem, actually, because after this activation, I discovered it’s not as resonant as I’d like on the 20, 15, and 10 meter bands, so I may tinker with the toroid windings a bit–perhaps removing one.

Instead, I deployed my MM0OPX EFHW which I thought was actually a great choice considering propagation had been incredibly unstable the previous few days.

Since I also had my Elecraft KX2, I knew I could use its built-in ATU to move to non-resonant bands like 17 and 30 meters.

This activation video is a long one because I had quite a lot of time to play radio and, frankly, it was nice taking things at a casual pace.

After deploying the antenna (twice!) I set up the radio, connected my Begali Traveler, and hopped on the air! Continue reading Postcard Field Report: Pairing the Elecraft KX2 and MM0OPX EFHW to face dubious propagation

Hike and Talk: Using best practices

Last month, I recorded another “Hike and Talk” session before a POTA activation at K-4861. If you’re not familiar with my “Hike and Talk” series, these are long-format, unedited videos where I hike (camera in hand) and cover a topic that’s not easy to encompass in an email reply or even blog post.

This particular topic was even difficult for me to title–!

I receive a lot of questions and feedback from readers about my field deployments and choice of antennas, feedline, power output levels, etc. Most of the time, these are readers who are genuinely curious why I’m not using “best practices” in my POTA/SOTA activations; deploying the highest efficiency antennas, using more counterpoises, running 100 watts, etc. etc.

Truth is? It’s all about context!

My field radio station, for example, isn’t set up to the same standard as my home or QTH station…for good reason, actually! The “best practices” I use at my home station aren’t always the same as the ones I use during a POTA activation.

I hope you enjoy this video and would welcome your constructive comments.

Are you prepared for Radio First Aid?

by Vince (VE6LK)

(As is Vince’s usual, this article has a bunch of links – click on as many as you wish for the full experience)

Before I go too far into this topic, I wish to first offer hearty congratulations to Thomas Witherspoon for having one thousand posts on QRPer.com! Woo-Hoo!

Do you pack a Radio Field First Aid kit?

On my recent trip to VE3-land I had a few opportunities to practice set-up with my gear–away from the safe place that is my truck–to ensure I’d brought everything for my trip to Hamvention and activations along the way. I did forget an audio cable, however a visit to a local dollar store solved that problem inexpensively.

So, unless you pack two of everything -because two is one and one is none– you should expect that something’s going to fail or break along the way. What you never know is when or how that’s going to happen. I wouldn’t be writing this story if it had not happened to me before.

This time it was on a Sunday outing to VE-1512, the McLaughlin Bay Reserve Wildlife Area in Oshawa Ontario and far away from the comforts of my shop at home. Tucked away not far off of the 401 Highway, this nature reserve is a calm and peaceful oasis just minutes from urban life. I saw kayakers, hikers and trail runners during my visit.

Setting up my Comet HFJ-350M, I added the jumper cable to set the antenna for 20m and then I started to push the antenna down into the ground onto the stake. And that’s when my hand slipped and I broke the jumper cable connector, busted off in the hole.

Broken pin that triggered my outward potty mouth

For the inquisitive among you, my inner potty mouth made a brief outward appearance, ahem. Continue reading Are you prepared for Radio First Aid?

Lakefront QRP and Bags Galore!

by Vince (VE6LK)

(As is my usual, this article is full of hyperlinks – click on as many as you wish)

The days leading up to my first Hamvention trip were a bit scattered to say the least. While I was pretty sure I remembered everything and even documented most of my gear on Twitter, I would only discover that the bag I intended to carry my gear around in was too small once I arrived in VE3-land. The very next morning I was shopping in several big box stores trying to find the perfect bag only, hours later, to discover an Army Surplus Store across the street from my activation and after the activation concluded.

Holey Moley lookit all the molle and backpacks!
Thomas’ reaction upon seeing this photo was predictable 😉

Anyways, the short summary on the shopping trip was that I figured out a way to get me through the trip without spending a fortune.

The day’s goals were to make a simple activation at a park near the family where we were visiting east of Toronto. Before travelling I scoped out POTA entities that were nearby and had not yet received a CW Activation thus putting me closer to my CW goal for the year.

I landed up at Lakefront West Park VE-1480 in Oshawa Ontario.  A recreational trail winds along the waterfront of Lake Ontario about 100m away, and eight baseball diamonds are the central feature here. Given the lack of trees at the park, and that I do not have a small mast on this trip for my EFHW -although I may remedy that at Hamvention- I chose to deploy my Comet HFJ-350M with some simple ground radials. With the solar reports showing SFI 149, SSN 134, A 19 and K 2, I chose 20m as the band for the day. 5W on my KX3 into a ground mounted vertical with one each 66′ and 33′ radial wires would have to be enough.

I have the full Comet HFJ-350M kit including the bag to carry all the pieces in. I also have a ground stake from eBay that comes with a 90 degree SO-239 adapter allowing me to attach feedline on the side and the antenna on the top. Not including the ground radials, the whole kit rolls up reasonably small, about 3″ in diameter and 12″ long. Continue reading Lakefront QRP and Bags Galore!

Postcard Field Report: Pairing the Elecraft KX2 and Packtenna 9:1 Random Wire at Holmes Educational State Forest

Well, I’m off to Hamvention in two days and trying to prepare for the trip. There’s so much to do!

If you are attending Hamvention this year, I’d love to meet you. Stop by the Ham Radio Workbench/Halibut Electronics table (#3011) and introduce yourself.

Since my travels this week are imposing on my field report time, I’m going to share another, shorter, Postcard Field Report. I hope you enjoy it:

Holmes Educational State Forest (K-4856)

On Friday, April 21, 2023, I had a short window of time to fit in an activation while my daughter was attending her high school robotics class.

Her robotics class lasts nearly two hours, but it’s 30 minutes away from all parks and summits, so traveling to/from a site takes about one hour.

I didn’t care because I had a particular park in mind: Holmes Educational State Forest (K-4856).

It had been one year almost to the day since I last activated Holmes.

I arrived on site around 13:30 local, and there were only a few other people floating about.

I walked up the main loop path in search of a good picnic table that was out of the way and with ample trees about.

In a pinch, any of the picnic table sites would have sufficed, but since I practically had the whole park to myself, I could afford to be picky!

The sign above reminds me that Educational State Forests in North Carolina have hours that vary by season and truly cater to school groups, thus are primarily open during the school day. Always check those hours before embarking on a journey to this type of park.

One great thing about our Educational State Forests is that they almost always have a nice covered picnic shelter for school groups. If they’re not occupied, they’re perfect for POTA activators who’d like to escape heavy rains. You can see the one at Holmes off in the distance in this photo:

I ended up choosing the same picnic table I used last time–it had more room around it to set up an antenna without crossing the path.

I didn’t have a lot of time to set up and operate, so I chose to use one of my speedier deployment combos: the Elecraft KX2 and PackTenna 9:1 Random Wire. Continue reading Postcard Field Report: Pairing the Elecraft KX2 and Packtenna 9:1 Random Wire at Holmes Educational State Forest
