Tu-Endie-Wei State Park: Low-impact QRP fun and one speedy P2P confirmation!

On Wednesday, May 17, 2023, I did something I hadn’t done since 2019: I woke up, hopped in the car, and started my journey to the Four Days In May and the Dayton Hamvention!

It’s about a seven hour drive from my QTH directly to Dayton, but in the 12+ times I’ve attended Hamvention, I’ve never actually driven there directly. Instead, I drive to Athens, Ohio, spend the evening with my buddy Eric (WD8RIF) and his family, pack one car, then carpool to Dayton.

Heading to Athens, I like to time my drive so that I pass through Beckley, West Virginia around noon and enjoy a fine lunch at Tamarack Marketplace. It’s always a nice reward after spending a little over four hours in the car.

This year, I enjoyed local almond-crusted rainbow trout, braised kale, and dill pickle soup. I know…dill pickle soup sounds a bit strange, but trust me: it was exquisite. The food at Tamarack is always top-shelf because the chefs behind the scenes are training for positions at the famous Greenbriar Resort.

Park en route

Of course, another way to break up the trip and add a little fun is to activate a park. I decided I wanted to activate a new-to-me park not too far off my route, so I consulted the regional POTA expert: WD8RIF.

Eric is an avid park activator and has hit pretty much every park within a three hour drive of his QTH. He made a few suggestions, and I opted for Tu-Endie-Wei State Park in Point Pleasant, West Virginia.

Tu-Endie-Wei State Park (K-1823)

Tu-Endie-Wei is a small, four acre state park, situated at the confluence of the Kanawha and Ohio rivers in Point Pleasant, WV. Indeed, the name “Tu-Endie-Wei” is a Wyandotte word meaning “point between two waters.” Continue reading Tu-Endie-Wei State Park: Low-impact QRP fun and one speedy P2P confirmation!

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.

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

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

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!

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!

Pit Stop Style Activation with Elecraft KX3 and AX1

(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

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?

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

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.

DX Toolbox on iOS – click for App Store link

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!
