Carolina Beach State Park: A QRP Oasis Amidst the Summer Heat and Activities

3 Comments

Tuesday, July 9, 2024, was a very radio-active day!

I was in Wilmington, North Carolina, and that morning, I had the privilege of activating the Battleship North Carolina from inside the battleship. Click here to read the field report and watch the video.

In short? It was amazing and certainly a fabulous way to start the day.

We were in Wilmington because one of my daughters was attending a week-long program at NC State University, and the other was attending a similar program at UNC Wilmington.

That Tuesday afternoon, after dropping my daughter off on the campus of UNC Wilmington, my wife suggested we hit Carolina Beach State Park for a POTA activation. It didn’t take me a microsecond to agree to that plan!

Carolina Beach State Park (US-2722)

Carolina Beach State Park, located just south of Wilmington, is a unique spot full of natural wonders. The park covers over 760 acres of Pleasure Island, with diverse habitats ranging from the impressive 50-foot Sugarloaf Dune (which used to be used as a navigational aid) to the fascinating limesink ponds, each with its own special plant community.

The park is also home to the Venus flytrap, a rare carnivorous plant found only in a small part of the Carolinas. You can explore the park’s trails, winding through maritime forests and maybe even catching a glimpse of these fascinating plants in action. The park also has a marina for easy access to the Cape Fear River and the Intracoastal Waterway, making it a great spot for boating and fishing.

We arrived at the park a little before 4:00 PM local time. Had it not been so hot and humid, we would have hit one of the park’s trails before finding a spot to do POTA, but the weather being what it was, both of us were happy to spend time in the shade.

We pulled into the main picnic area and quickly found a spot to set up. As I pulled out my radio and camera gear, my wife, Heather, pulled out her travel watercolor kit, all packed in a Tom Bihn HLT1 (we’re a pack geek family!).

When Heather joins me on POTA activations, she almost always sets up somewhere and paints while I activate. I love the fact that we both enjoy the experience in different ways.

In fact, my buddy Steve (KC5F), who is also an avid POTA activator, performs almost all of his activations with his wife, who also paints while he activates. He told me that she likes a good couple of hours of painting, so he typically racks up a lot of contacts in that amount of time.

Setting Up

The first thing I did was set up my Thermacell mosquito repeller–it needs a few minutes to do its thing and clear out the mozzies. The model I carry, the “backpacker,” fits a standard backpacking stove canister. I’ve recommended this one to many other POTA ops who operate in areas with mosquitoes–so far, it’s never let me down!

Also, I want to send a big shout-out to Alanna (K4AAC) and Bob (K4RLC) for making this activation even more civilized.

After watching an activation earlier this year at Tuttle Educational State Forest, where I placed my KX2 and logbook on a wet and dirty picnic table–covered in pollen and other tree bits–Alanna ordered a blue Gingham picnic tablecloth and whisk and had it sent to me.

I’ve had this tablecloth packed in the go-box I keep in the Subaru, and this activation was the perfect time to put it to use because the table I chose needed cleaning!

Thanks, Bob and Alanna!

Next, I deployed my PackTenna 9:1 End-Fed Random Wire antenna and paired it with my Elecraft KX2.

New paddle mount!

I did (finally) get to try out a new piece of kit in the field: a newly-designed paddle mount from Steve (KB3SII) at QRPworks.

Steve handed this prototype mount to me at Hamvention this year. It’s an updated design of one we tested last year.

You basically attach the mount to the front of the KX2 (or KX3) and place a paddle like the Bamakey TP-III that has strong rare earth magnets. The paddle locks onto the metal pad and makes for a rock-solid, ergonomic keying experience.

Steve also sent me two short 3.5mm angled cords to connect the key to the radio, but I forgot to pack them for the trip. My standard paddle cable worked fine, although I had to angle the TP-III slightly.

Note that Steve plans to have these paddle mounts in production and available on the QRPworks website in the coming weeks. When they’re available, I’ll post a direct link.

With the KX2 set up and ready to go, it was time to hit the air!

On The Air

I started calling CQ POTA on 17M and discovered that it was a fairly quiet band. Nonetheless, I worked two stations in about six minutes. Secretly, I was hoping there might be a 17M path into Europe, but then again, it was a bit late in the day for that (and it seemed 17M wasn’t terribly energized).

One CW Question series draws to a close after 6 months

9 Comments

by Vince (VE6LK)

Firstly, a huge shout-out and thank you to Thomas K4SWL for letting me hang out here on QRPer.com and exercise my creative writing chops, and to the community at QRPer.com for giving me such excellent feedback in my original article – both of which propelled me into this fun project.

Sometimes I begin my creative writing on a notepad with pencil, and sometimes I just type it out.

On January 20th 2024, I posted a simple question to readers of QRPer.com, If you could tell new CW learners your single best tip to learn CW, what would it be?

I was overwhelmed with the response in the comments and realized I had struck a nerve. At least one person told me that I should have bought a lotto ticket with that sort of luck, but I’ll tell you all that I am richer with the knowledge I’ve gained and shared with others as a result of the interviews I conducted with the who’s who of the English-speaking CW world.

My first key, on the right. Yes, a converted joystick. Yes, I did my exam with it.

It’s with a mixed heart that I’m here to announce that project has drawn to a close. It’s been tremendously helpful to so many people. Here’s the final episode and my personal tip to all of you aspiring CW learners.

I’m blessed to have met so many interesting people along the way and forged new friendships as a result.

Additionally, extra special thanks to Tim N7KOM, Alan W2AEW and Adam K6ARK who, along with Thomas, were my first victims interviewees where I was able to refine my interviewing and video editing process. And, Adam gave me a great idea – refine the videos into YouTube Shorts format. These refined Shorts are called 1CWQ and are the essence of each tip I recorded. The credit for the Shorts really belongs with Adam.

My entire family of keys (minus one in my truck and the others pictured above). W8BH Morse Tutor kit seen in the back of the photo. Visit my website to get your kit.

I interviewed 53 people for the series and produced well over 100 videos as a result as some gave us (you and I) more than one tip. If you missed the series, it’s not a ton of hours to binge watch. The original recordings are 2-3 minutes each and the shorts are all under one minute, or else YouTube won’t let me call them a short. You can find the Original playlist here and the Shorts playlist here.

I hope you enjoy these CW tips at least half as much as I did in recording and editing them.

One final tip, direct from my friend W5WTH who offers the following excellent advice in words better than I could ever say:

“Don’t let perfect be the enemy of good. Most CW ops are patient and can recognize a new op right away. They will most likely be happy to work you at a slow speed because they recall their personal CW journey. SKCC and POTA are the two easiest, stress free ways to make a CW QSO. Once you get the numbers and letters learned then start trying to get on the air. Don’t worry if you screw up because we all screw up and try to get better…”

I’ll add here that CW means never having to say SRI (CW shorthand for sorry) <GRIN>. Also Pat W5WTH has an excellent website too!

Handmade key left to me by VE6AB

Lastly, this is the story behind the straight key featured in all of the videos and in the main photo for this article. The key was hand crafted by my friend VE6AB, Jerry Clement, now a silent key. Jerry was a creator, maker, master machinist, backcountry hiker and camper, and photographer – a real true Renaissance Man in every sense of the word. His photography graced the covers of QST Magazine often in recent years.

At a time when CW was required for HF privileges in Canada, Jerry did his CW exam with this key and he told me once it was a real attention-getter at that testing session! Upon his passing it was bequeathed to me with instructions for me to use it and to keep my [at-that-time struggling] CW skills up. The only parts he did not manufacture were the ball bearings and the rubber feet – all of the other parts were crafted in his hands. I shall always treasure this beautiful key.

Thank you, Jerry, for encouraging me from the great beyond. DididiDahDiDah

Sweat, Signals, and History: A POTA Activation from the Battleship North Carolina’s Radio Room!

29 Comments

Those of you who know me know that I’m a huge World War II history buff. Ever since I was a child, I’ve been fascinated by the stories of bravery, sacrifice, and technological innovation that defined this era.

That’s why the activation I performed on Tuesday, July 9, 2024, was very special.

I activated the Battleship North Carolina from inside the ship, using a modern transceiver, and one of the original vertical antennas mounted on the ship.

The Battleship North Carolina State Historic Site (US-6831)

The Battleship North Carolina is a World War II-era battleship that served in the United States Navy from 1941 to 1960. It is currently a museum ship in Wilmington, North Carolina.

The ship was launched in 1940 and commissioned in 1941. During World War II, it served in the Atlantic and Pacific theaters, participating in several major battles, including the Battle of the Atlantic and the Battle of Iwo Jima.

The Battleship North Carolina was decommissioned in 1960 and donated to the state of North Carolina in 1961. It has been open to the public as a museum ship since 1962.

Growing up in North Carolina, I’ve always considered the Battleship North Carolina the icon of Wilmington. You can’t cross the Cape Fear river and miss this brilliant bit of naval history–it’s so prominent and accessible.

I had not actually toured the battleship since I was a child–some 40+ years ago. Last week, however, our family spent the week in Wilmington and the battleship was first on the to-do list.

Azalea Coast Amateur Radio Club

A couple months ago, I mentioned to my buddy Bob (K4RLC), in passing, that one of my daughters was attending a week-long residential program at NC State University while the other daughter would be attending The University of North Carolina Wilmington. My wife and I would stay in Wilmington for the week and I would somehow love to activate the Battleship North Carolina for the POTA program.

Fortuitously, shortly thereafter, Bob attended a presentation about the Battleship North Carolina by Mike Hartmann (NI2S) at a radio club meeting in Raleigh. Mike is with the Azalea Coast Amateur Radio Club, the caretakers and curators of radio central in the battleship.

Bob put me in touch with Mike who then graciously accommodated my schedule, even though it required his presence throughout the activation.

Mike did make it clear that the radio room is three decks below, has no air conditioning and is a proper “sweat box.” Turns out, too, that the week we were in Wilmington coincided with a bit of a heat wave which was affecting much of the eastern US. Because of this, I asked if we could meet on Tuesday, July 9, 2024, at the earliest possible time–8:00 AM, when the museum opened.

It was a beautiful morning and I arrived on site perhaps 15 minutes in advance. I needed to pull my camera gear out of the car and allow some time for it to adjust to the humidity (which was extremely high).

I thought my lens had finally acclimatized when I started the video before Mike arrived, but it turned out the lens was still a bit foggy for a minute or two.

Mike arrived and we walked into the ticket booth where I purchased my ticket. He then led me onto the deck and into one of the roped-off entrances to the lower decks.

He kindly allowed me to film walking through the ship into the radio central area. I’ll admit that it was difficult for me to keep my attention on the camera as I was walking through a ship I remembered from my childhood! Since my video is real-time, real-life, you experience it with me–I didn’t check out the ship in advance.

I was amazed at how much of the ship was open to the public and in superb, original condition.

In radio central, Mike allowed me to peek behind some of the closed off sections with my camera, so you’ll get the follow along with me.

What I didn’t realize was just how much signal intelligence was happening on a fast battleship like the USS NC.

There were rooms dedicated to listening posts, decryption/encryption, and sharing of intelligence. This was all so fascinating and enlightening.

Next, Mike opened up the actual radio room where an Icom IC-756 Pro III was hidden in one of the original ship radio desks. This being a museum, all modern gear was hidden as well as possible.

Mike was right about the room being a sweat box–even in the early morning, it was pretty hot and humid in there. Fortunately, he had two fans he turned on and pointed at us.

The view from my operating position.

Mike set up the IC-756 Pro III by connecting it to a power supply, then attaching a Bencher paddle.

The vertical–again, one of the original Battleship North Carolina antennas–also required a little bit of matching for 20 meters.

Any movement of 10 kHz or so, required engaging the 756’s internal ATU.

As I set up the camera and made a comfortable operating position, I realized just how noisy the room was with the normal ship sounds (it has its own fresh air ventilation system) and the two fans running full-bore.

I set up my wireless mics–one on me and the other inside the portion of the desk that housed the radio.

In truth, I wasn’t confident the audio would work out at all. First thing I did when I made it back to the house that day was to check the audio–turns out, it came out pretty darn well all things considered.

In fact, the audio in the video was much better than my own two ears experienced while operating. Having one of the mics much closer to the speaker and protected from the wind blowing really made a difference.

Case in point: In the video, you’ll see I struggled to copy OE6GND–his signal was weak, but I copied it first go when I listened to the video. Continue reading Sweat, Signals, and History: A POTA Activation from the Battleship North Carolina’s Radio Room! →

Morning POTA with KM4CFT: Back-to-Back activations with the venerable Yaesu FT-818!

6 Comments

As I write this report, I’m on the road with my family–we’ve been spending the week on the coast of North Carolina and are now (at time of publishing) in Raleigh. I’ll keep this field report short and sweet so I can publish it quickly and also fit in an activation before record temps heat up the region!

Blue Ridge Parkway (US-3378)

On the morning of July 4th, 2024, Jonathan (KM4CFT) and I arranged to meet and activate on the Blue Ridge Parkway (US-3378).

Jonathan was in town visiting family over the holiday weekend, and I had a brief window of time that morning to join him. My schedule had been packed since Field Day, making this my first chance for a POTA activation for a couple of weeks.

We knew it would be an interesting activation right from the start: we both arrived at the Folk Art Center at the same time and were greeted by a large black bear strolling down the road in front of the entrance! A bear walking away from your POTA spot is always a good thing.

After a quick catch-up, I grabbed my arborist throw line and deployed the 30/40 meter linked end-fed half-wave antenna I’d built using the KM4CFT antenna kit.

It would have been rude to use another antenna with KM4CFT standing right there! (Note to N5FY: Yes, I know I’ve been rude to you on many previous activations, haha!)

On The Air: The Accidental Self-Spot

Jonathan took to the air first. Since neither of us had announced our activation, I opened POTA.app to spot him. Except, I didn’t. In a moment of confusion, I accidentally spotted myself!

It turns out there’s no easy way to delete your own spot once you’ve done that. (If there is, I’d love to know, though I hope to never make that mistake again!)

What followed was rather comical. Jonathan noticed people thought he was me, even though he used his own callsign in each exchange. I guess it’s easy to mishear a callsign when you think you already know it!

I kept spotting myself “QRT,” but many kind operators kept re-spotting me. I even moved to 14,000 kHz (an out-of-band frequency I’d never use) and spotted myself QRT. People were still re-spotting me on Jonathan’s frequency!

It was funny, and the early morning hour on a holiday probably contributed to the confusion.

After Jonathan logged his ten contacts, he handed the radio over to me. I swapped out paddles (his TP-III setup mounted to the FT-818 wasn’t comfortable for me).

I started calling CQ POTA de K4SWL, spotted myself (correctly this time!), and the real activation began.

In the end, I worked 25 stations in 26 minutes. Thanks to all the hunters!

Then it was time to call QRT and continue our day. It was great seeing Jonathan and fitting in a little POTA before the day really started!

QSO Map

Here’s what this five-watt activation looked like when plotted out on a QSO Map:

Activation Video

Here’s my real-time, real-life video of the entire activation.  As with all of my videos, I don’t edit out any parts of the on-air activation time. In addition, I have monetization turned off on YouTube, although that doesn’t stop them from inserting ads before and after my videos.

Note that Patreon supporters can watch and even download this video 100% ad-free through Vimeo on my Patreon page:

Thank you

Thank you for joining me during this activation! (And thank you, Jonathan, for joining me!)

I hope you enjoyed the field report and my activation video as much as I enjoyed creating them!

Of course, I’d also like to send a special thanks to those of you who have been supporting the site and channel through Patreon, and the Coffee Fund. While not a requirement, as my content will always be free, I really appreciate the support.

As I mentioned before, the Patreon platform connected to Vimeo makes it possible for me to share videos that are not only 100% ad-free but also downloadable for offline viewing. The Vimeo account also serves as a third backup for my video files.

Thanks for spending part of your day with me! Have a brilliant week ahead and be kind to one another out there!

Cheers & 72,
Thomas (K4SWL)

New 3D-Printed Paddle Kit from KM4CFT

1 Comment

Yesterday, I met up with Jonathan (KM4CFT) who happens to be in town visiting family over the holiday weekend. Before our POTA activation, he mentioned that he is now selling a 3D-printed paddle kit for $34.95 on eBay:

https://ebay.us/GhLOYz
(note: this is an eBay partnership link)

Jonathan told me that he’s using the kit as a bit of a fund-raiser for a much more ambitious project he has in the works.

Jonathan gave me an early prototype of this key many months ago (see photo above) and I’ve used it in the shack and in the field. It’s a good one.

This kit version has either red or blue finger pieces.

As with all of Jonathan’s kits, he’s selling this kit via the eBay shop of Dan (W7RF). Go check it out!

Friedrichshafen: Christian and Andrea’s Multi-Country POTA Rove

Many thanks to Christian (IX1CKN) who shares the following field report:

Friedrichshafen: POTA Across Borders

by Christian (IX1CKN)

The Friedricshafen fair is one of the most interesting events for its social aspects, where you can finally put a face to colleagues whose voices you’ve only ever heard. Among the various OM (radio amateurs) I met this year was Gabriele IT9RGY, a flagbearer of the Italian Contest Club. When he recognized Andrea IW0HK and me, he said, referring to our respective SOTA/POTA activities: “You two are the real deal.”

I found that to be a very powerful statement, and I am grateful to him for it. Personally, I try to document each outing to capture the sensations it gave me, but also in the hope of inspiring someone. Andrea is more succinct than I am (if we were all the same, the world would be boring), but his spirit is identical. Parks on the Air (POTA) is a state of mind. It was no coincidence that, being in Germany for the Hamradio Messe, we had planned a series of activations.

Our schedule was tight and ambitious, and just completing it was a source of happiness, but there’s more to tell. In Germany, dinner time isn’t synchronized with Roman schedules. So, on Friday evening, after leaving the restaurant (for dinner with the Summits On The Air group) at 20:23, I looked at Hotel-Kilo and said, “If I go to bed now, I’ll digest in a week; let’s go activate a reserve!”

The easiest option in the area (after a disastrous experience last year in DE-0156, the park in the town center hosting the fair) was DE-0766, the Seewald Landscape Reserve. It’s near the FRN airport (and thus not far from the fairgrounds), in a fully bucolic setting. A narrow road cuts through meadows, with footpaths and bike paths leading into a wooded area.

We parked the car in one of these spots. It took only a moment to set up the vertical antenna in the field, but the presence of a swarm of mosquitoes as big as F-18 Hornets advised us to operate from inside the car to save our skin (literally).

Andrea turned on the KX-3 (10 watts would be our fixed power for this trip), and the 14 MHz calls began. Right away, a very strong IZ3QFG Dario (just 380 km from us) answered, highlighting an unusually short skip.

We logged 20 QSOs in 30 minutes… Many were from Italy (Spartaco from Grosseto at full scale, Mauro I1JQJ always active, and Beppe I1WKN a constant), with two “park to park” contacts. A classic for many OMs in the area, but also a great mood booster and a tasty appetizer for the next day… Continue reading Friedrichshafen: Christian and Andrea’s Multi-Country POTA Rove →

Experimenting during Field Day 2024

6 Comments

by Vince (VE6LK)

Field Day 2024 started out with the best of plans to be spent with the best of friends and ended up totally different – and, unexpectedly, I had a hoot! With my carefully made plan behind me, my new last-minute plan was to run solo for Field Day in the backcountry of Kananaskis Country and bring along my new-to-me Nikon D3400 and lenses and rekindle my interest in (D)SLR photography at the same time as doing some experimentation with radio gear.

I grew up in a home with a scratch-built enlarger and a darkroom, so a love of taking pictures has been with me for a long time. My Father taught me patience to get the shot as he would set up a 120 format bellows camera on an air-triggered remote release to get closeups of chipmunks while we were camping, a process that took hours and yielded excellent results. My Brother, AG7GM, has attempted to instill within me the basics of composition, rule of threes and such and his wonderful skill in editing both stills and live video. While I have plenty of patience, with composition I think I’m fair to middling at best.

Thus photography has always been on my mind.

With a recent sale of a few ham radio related items, I had fun money, so just for fun I started looking [on Thursday before I activated] at used DSLRs and was shocked at how much camera I can get for such a relatively low cost compared to new. I had said once, 25 years ago when I divested out my 35mm kit, that when I could get a DSLR with a 25 to 300mm lens for <$500 I’d jump in… and finally that day is here, even if it means carrying two lenses. Of course, I started looking on the day before Field Day for deals – and scored them too! 🙂 Around these parts, good quality pre-owned consumer grade DSLRs are easily available. I purchased this as much for still photography as for ability in shooting high-quality video for my YouTube channel.

These peaks form part of the border between Alberta and British Columbia to the west

For me, Field Day has always been about the experimentation rather than chasing points. Trying new things. Changing up from the normal way I operate in the field. Comparing, analyzing and making notes as I go.

For example, and as a tribute to Chip Margelli K7JA (SK) after corresponding with his brother David, last year I attempted to wet a piece of string and see if the KX3’s tuner would match it and radiate a signal. Chip was known for many things, among them his proficiency in CW as he demonstrated on The Tonight Show with Jay Leno in 2005. David told me that he and Chip would do crazy and fun experiments like loading up clotheslines and wet string to experiment .. and it fostered a new direction I could take each FD and on some days between. The string experiment was a failure last year but I haven’t given up yet!

This year, I wanted to work with a few different antennas and a Charmast 100W battery pack from Amazon along with a USB-C PD 12v power cable for my KX3 [note: Amazon affiliate links!].

I wanted to know, in no uncertain terms, that the Charmast would or wouldn’t be as quiet as my trusty Talentcell LiFePO4 pack. The Charmast is also used in my field soldering kit with a Pinecil as it delivers USB-C PD. What better way to test this out than to head as far away from noise sources as possible, see the Canadian Rockies in their early summer glory with snow on the peaks, rivers running high (and cold) and the sun in the sky? Just for grins I would ensure that I was in POTA entities while doing Field Day.

Bletchley Park

Most readers of this blog are probably familiar with Bletchley Park and the significance of this place in breaking the codes used by the axis military forces during the second world war.

The electromechanical systems developed and used here to aid the codebreakers in their daily work led directly to the electronic digital computers of the mid-twentieth century, and then to the modern world as we know it.

After boarding the London Northwestern Railway at Euston station, the hour long train journey took us from central London, through the suburbs, then the pastoral English countryside to the station at Bletchley, just south of Milton Keynes.

Bletchley Park is a five minute walk from the train station at Bletchley, the town of the same name. In keeping with the formerly clandestine nature of the work at Bletchley Park, there are no loud signs to welcome you, just the Union Jack flying over the nondescript visitor center in Block C.

Exiting the visitor center, any ham will quickly spot the three-element SteppIR Yagi perched atop a roof-mounted tower. Also from the tower, a folded dipole extends over the the Block B building which houses the Alan Turing museum exhibits. The other end of this antenna farm is plugged into GB3RS, the amateur radio station for the National Radio Centre of the RSGB.

The friendly and helpful staff of amateurs at the NRC played a crucial role in my hoped-for plan of activating Bletchley Park for Parks On The Air.

Surprisingly, the POTA page for GB-0507 showed only a handful of activations of this iconic location. Seeing as this is a heritage site, I sent an email to the NRC about week before my visit asking for advice on how to be a welcome guest POTA operator.

Note, the NRC is colocated on the grounds of the museum but they are not a part of Bletchley Park. The NRC is a separate organization.

Martyn G0GMB, the Director of the NRC, kindly responded to my enquiry and informed me that individual amateur radio activity is not generally permitted on the grounds of Bletchley Park due to the number of visitors they receive and concerns about RF safety. This could explain the low number of activations.

The sharp eyed will spot the GB3RS beam across the pond.

Martyn suggested I could set up in the overflow car park few minutes walk down the road from the visitor center. While not on the grounds of Bletchley Park proper, the parking lot operation would still be in the spirit of POTA and would reasonably count as a valid activation location.

When I arrived at Bletchley Park on Friday afternoon, I was met by Mervyn G4KLE who was expecting me thanks to a note left by OM G0GMB. Mervyn asked where all my equipment was and I motioned to the pack on my back.

Because my radio and antenna was a low impact, minimal footprint QRP setup, I was told that I could make use of the picnic table just out the side door of the GB3RS shack, with my antenna setup just beside it. This dead-end spot was not on any of the paths frequented by park visitors and my antenna would not be easily visible.

The antenna is low profile

This was a much better arrangement than trying to activate from a car park without a car! I quickly deployed a GRA-GNT micro tripod with center spike pushed easily into the soft ground. The GRA-7350T loaded vertical and a set of short radials provided an SWR of 1.05 to 1.

I chose the QMX as a travel radio while in Britain because with it, the overall kit is very lightweight and compact. With the exception of the tripod the whole kit fits in my carry-on. The GRA-GNT antenna mounting kit has to fly in checked baggage due to several aggressive looking spikes that would certainly be flagged by airport security. Continue reading UK POTA Rain and Shine →

Xiegu X6200 SSB Field Test: A Morning POTA Activation at Lake James

11 Comments

On Tuesday, June 18, 2024, I needed to make a morning trip to Hickory, NC, to take care of some family business and visit my father.

I started my day early because I also wanted to be back in the Asheville area by noon. Some quick calculations over morning coffee and I decided I had just enough time to fit in one POTA activation en route to Hickory.

I left the QTH around 7:15 AM and made my way to the Paddy’s Creek Access of Lake James State Park, arriving around 8:15 AM.

Lake James State Park (US-2739)

Two other reasons I fit in my activation en route to Hickory instead of on my way back:

  • Paddy’s Creek has a lakeside beach area that gets very busy in the summer, especially on clear, sunny days (like Tuesday).
  • Temperatures that day were forecast to push near 95F/35C.

When I arrived at the parking area, I was pleased to see I was one of the only cars there. This made it much easier to find a spot to set up!

I started my activation video (see below) then walked to a picnic table under some trees that would not only provide shade but also antenna support!

I deployed my KM4CFT end-fed half-wave kit that I cut as a 30M EFHW with a linked 40M extension. When I launched the arborist line into the dense canopy, I thought I snagged a high branch, but it turned out I hadn’t.

In the end, my 40M EFHW had more of a low inverted vee, almost NVIS-height, configuration. I was fine with that, though, knowing on the 40M band that early in the morning, I’d snag contacts in NC and the surrounding states.

My goal was to finally make some SSB contacts with the Xiegu X6200. My previous mid-day activation with the X6200 provided no results, so I was hoping I’d be more successful in the morning.

One other thing I did that I haven’t done in over four years: I started out my activation with more than 5 watts of power. I added an external battery to the X6200, turned off its internal charger, and ran the transceiver at its full output power of eight watts.

My goal was to see how warm/hot the chassis would become during the activation. This is one of the questions I’ve been asked the most about the X6200 so far.

Setting up the radio was simple. I was careful to make sure that the internal ATU was bypassed on the 40M (and later 20M) band.

On The Air

One of the other reasons I chose the Paddy’s Creek access of Lake James is that I knew for sure that I had mobile phone reception there, which I would need to self-spot in SSB mode. Continue reading Xiegu X6200 SSB Field Test: A Morning POTA Activation at Lake James →

Sam’s Thunderbird Mk 1 Takes Flight: A Homebrew Radio Field Report from the American Southwest

Many thanks to Sam (WN5C) for sharing the following guest post:

Homebrew in the Field

by Sam (WN5C)

What a week it’s been!

I have the opportunity to spend a month traveling through and camping in the American Southwest (specifically, New Mexico, Arizona, and Colorado) doing archaeological work. And of course, that means the prospect to operate portable at weird times and in lots of places.

I’ve been planning for this trip for a couple of months, about the same length of time that I’ve been trying to achieve my amateur radio dream: to build a complete transceiver. So why not try to do both things at once?

This is just a quick note of my experiences in the first quarter of my trip of taking a homebrew rig into the field.

First off, I have absolutely no background in RF engineering, or electronics at all. But the literature is good and Elmers are priceless (thanks Kenn KA5KXW!). I started small, with kit projects, and then very basic transmitters.

I’ve always appreciated how much satisfaction my father gets by building things by hand, and finally I have a similar hobby. I called the radio I designed the Thunderbird Mk 1 based off the fact that I cut my CW and POTA teeth at Lake Thunderbird State Park in Oklahoma and will probably continue to work there the most. It’s a 6-band (40, 30, 20, 17, 15, 10) CW QRP transceiver with SSB receive.

The receiver is direct conversion and is an amalgamation of VU2ESE’s DC40, KK7B’s Classic 40, and W7EL’s Optimized QRP Transceiver. The VFO is an Arduino/si5351 combo based on the schematics and code written by VK3HN (who has helped me from afar, thanks Paul!). It’s crude, but I use a 6-position rotary switch to manually switch between the band-pass filters.

The transmitter is based on W7ZOI’s Updated Universal QRP Transmitter, married with VK3HN’s Arduino code that acts as the oscillator, keyer, and side tone generator. I get about 3 watts output for 40, 30, 20, a little less for 17 and 15, and about a watt on 10 meters. Like the receiver, I manually switch the low-pass filters.

Here’s a picture of the digital parts (ignore the second Arduino Nano, I thought I would need it but did not), the power board, and the filters. It’s on the bottom:

On top is the main board with the receiver, the transmitter, and T/R switching. Also, you’ll notice the green PCB. I *really* wanted to build NM0S’s Hi-Per-Mite from scratch but I couldn’t get the circuit to run right before my trip so I opted to install one that I built from a kit. It’s a fantastic CW audio filter that I can switch in and out (everyone should have at least one!).

I can switch in a little speaker and added a straight key jack. I printed the box on a 3D printer at the local library. It works great for the shack. In the sun, it’s starting to warp in the heat, so I’ll have to address this, but things still work!

Getting out the door on time with a finished radio was tough! I had finished right before I left on my trip (end of May 2024) and had no time to field test. The best I got was taking the rig to the table in the back yard and firing it up during the WPX contest.

I made amazing DX contacts on all the contest bands I had and called it good. But working superstations isn’t real life, and over the next week I’ve had to MacGyver the radio (rigging a car jump pack, an inverter, and a soldering station together at a picnic table to replace a bad transistor, for example). I think I’ve finally shaken out (literally) all of the loose solder joints and bad grounding.
