Tabletop QRP POTA: A Father’s Day Getaway to Mount Mitchell State Park

14 Comments

When our family needs a change of scenery without a long drive, Mount Mitchell State Park is our go-to destination. I’ve mentioned before that it’s my “happy place” here in North Carolina. Mount Mitchell is only about 6 miles from our home as the crow flies, but it takes about 50 minutes to drive there, and it’s not in the direction of any of our usual destinations. Heading up the Blue Ridge Parkway and watching the flora change with elevation makes it feel like a proper getaway.

On Sunday, June 16, 2024, we wanted just such a getaway, as my wife and daughters were treating me to some Father’s Day fun. After visiting my father-in-law in the hospital in the early afternoon, we drove to Mount Mitchell.

Mount Mitchell State Park (US-2747)

Sundays on Mount Mitchell tend to be busy, especially in the summer. However, on this particular Sunday, it was rainy, foggy, and there were storms in and around the area.

Weather like this never bothers us on Mount Mitchell, as it can shift in an instant, as long as thunderstorms don’t intrude.

As soon as we arrived, I grabbed my radio bag from the car and found an empty picnic shelter. I’d been hoping for a free shelter since it was raining, and fortunately, we got our pick!

One of the first things I did after dropping off my pack was to tie Hazel to a picnic table because she was laser-focused on a chipmunk she saw run up a tree next to the shelter. That dog drives chipmunks and squirrels crazy, I’m sure.

My wife and daughters dropped off some art supplies at one of the shelter tables, then went on a short hike while I performed my POTA activation.

Note that Mount Mitchell is also a SOTA summit, but the picnic area is not within the activation zone. I could have easily gone to one of my go-to SOTA spots on the summit and knocked out a SOTA activation quickly (only four contacts are needed), but I wanted to save that for another day. Plus, being in the shelter meant that I could have a nice leisurely, dry activation!

I brought along my Penntek TR-45L and planned to pair it with a random wire antenna for the activation. However, since the weather was iffy—again, my primary concern was any thunderstorms that might sneak up on us—I decided to skip the wire antenna and go tabletop instead.

Fortunately, my Elecraft KH1 lives in my EDC bag at all times, so I set it up for tabletop mode.

New Tufteln KH1 Right Angle Adapter

KH1 “tabletop mode” gave me the perfect excuse to try out an accessory my friend Joshua (N5FY) sent me: his version of a KH1 right-angle antenna adapter.

You might recall that I have used the Elecraft KH1 adapter in previous activations and I think it works brilliantly. The first version of Elecraft’s adapter had one issue: the parts would fall apart if you weren’t careful with how you attached it to the KH1.

Joshua designed his right-angle adapter with captive components so that it’s all in one piece and can’t come apart.

I should note here that Elecraft actually updated their right-angle adapter design so that it also has captive components as well—so you have two choices! I’ll use the new Elecraft adapter in a future video and field report.

Joshua’s Tufteln design works really well (it’s also less expensive than the OEM adapter), and I like that it’s bright red, which means I’m less likely to leave it in the field!

On The Air

I assumed that 20 meters might be the most productive band that afternoon, so that’s where I started calling CQ POTA after snagging a Park-to-Park with K9NUD. Continue reading Tabletop QRP POTA: A Father’s Day Getaway to Mount Mitchell State Park →

WN5C: Notes from a homebrew POTA adventure

Many thanks to Sam (WN5C) who shares the following guest post:

Notes from a homebrew POTA adventure

Sam (WN5C)

I recently wrote about the homebrew transceiver I built to operate on a month-long trip through the American Southwest. Upon arriving back in Oklahoma here’s the final outcome: 27 days, 40 parks, and 669 QSOs. I honestly can’t believe that the rig went the distance, or that I made so many contacts on 2 watts or less!

The priority of this trip wasn’t radio, though. I’m an archaeologist and I’m starting a new research project that marries my historical interests with my love of two-way communication. In short, I’m studying the effects of how communication technology aided the American colonization and transformation of the western United States around the turn of the twentieth century. This means I walked and mapped single-wire telephone lines strung up in pine trees in northern New Mexico (used to connect fire lookouts with Forest Service ranger stations), a fascinating story of dramatic changes in land management. I also visited heliograph (sun-mirror signaling) stations established in southeastern Arizona by the U.S. Army Signal Corps in 1886 to assist in apprehending Geronimo.

Working Fort Bowie NHS (US-0815) in Arizona. The peak in the distance, Helen’s Dome, had a heliograph station on top. From the fort telegraph lines would have connected remote operations to the rest of the Army’s 1880s communication network. Next time I’m climbing up on top!

I look forward to relocating and studying the artifacts from more of these heliograph sites (mostly on remote peaks) to reconstruct this communication network and understand the lives of both the soldiers and the Apache, and how this novel surveillance system altered the battlefield. Based on the artifacts I’ve seen so far there are many cans of Army-issued proto-Spam and beer bottles surrounding the signaling station where American Morse Code would have been sent and received via flashes of sunlight. The original Field Day?

But back to radio. I covered a lot of ground and activated parks in Oklahoma, Texas, New Mexico, Arizona, Utah, Colorado, and Kansas.

The POTA sites that I activated (click image to enlarge).

At some locations I was camping so I was able to do multiple long activations and work the lower bands well into the evening. These were some of my favorite moments of the trip, being the only spot on the POTA app and leisurely working with no time or weather-based worries. It also gave me a chance to hear callsigns I was unfamiliar with, essentially exploring a new area of the country.

Working closer states after hours on 30 and 40 meters at Colorado NM (US-0918).

For other times, due to time constraints or weather (thunderstorms or that it was unbearably hot), I got my 10 contacts and moved on. Sometimes I packed the equipment for a long hike, often carried it from the car to a picnic table, and a few times deployed my antenna and operated from my vehicle.

Not every activation was a grand adventure. Sometimes, like here at Rocky Mountain Arsenal NWR (US-0226) in Colorado, I worked from the passenger seat in the car.

Every activation was memorable in its own way. I worked folks from 44 states, five Canadian provinces, and an unforgettable contact from Italy.

A map of the contacts I made (not including those in northern British Columbia, Alaska, and Italy).

The radio held up surprisingly well. Aside from it looking like a Dalí painting as the 3D printed box continued to deform in the heat, and some hot glue remelting, the electronic components worked as they should. I look forward to printing a stronger case and making some upgrades going into the fall. I do now have a real respect for the engineering that goes into designing field radios, especially those that are thrown into a pack!

Setting up a portable shack on Vail Pass in the White River NF in Colorado (US-4410). This was near the end of the trip, the plastic case was looking pretty bad.

After I began feeling less anxious about the homebrew radio (it kept turning on!) I could start focusing on the trip itself: an amazing POTA adventure with an often-uncooperative sun. Here’s a few themes I noted. Continue reading WN5C: Notes from a homebrew POTA adventure →

VO1DR Portable in Portugal: Coffee, Cobblestones and Contacts!

Many thanks to Scott (VO1DR) who shares the following guest post:

Coffee, Cobblestones and Contacts – Portable in Portugal

by Scott Schillereff, (VO1DR), St. John’s, NL, Canada

On a recent trip throughout Portugal (May 29 – June 12), I operated /P QRP CW at five locations, with varying success.  Here are some details and pictures that you might find interesting.

Portugal and /P sites

Figure 1 shows a map of Portugal and the five locations where I operated.  On this trip, we were on the move a lot, so radio was tucked in here and there when I found some free time.

Figure 1 – Portugal and operating locations. 1 Lisbon, 2 Faro (Algarve region), 3 Foz do Duoro (near Porto), 4 Funchal (Madeira island; off coast of Morocco), 5 Monte Estoril (coast west of Lisbon).

QRP gear

I was packing the following gear in a small compartmented zip bag:

  • ATS-V5 CW transceiver for 15, 12, and 10 m (small-run kit from Steve Weber, KD1JV; fits into lid-less Altoids tin).  My max P(out) was 1.7 W on 15 m rising to 2.3 W on 10 m.
  • Homebrew whip antenna system.  2.54 m telescoping whip on top of a 2 m camera monopod; raised radial (coiled up to preset lengths to resonate on each band); no ATU; directly wired via 5 m of RG174 coax to choke at rig.
  • Homebrew common mode choke – RG174 coax threaded through five FT37-43 toroids and coiled around a larger unknown ferrite core (scavenged from TV).
  • Homebrew resistive SWR bridge – common design to null out an LED at low SWR; max tuning SWR 2:1; switchable in and out of Tx circuit; direct BNC connector to rig
  • 30,000 mA-hr Lithium-ion battery– car jump-starter; lightweight (284 g); 15V and 5V no-load outputs; 15V output through voltage controller to rig.  One charge did entire trip.
  • Homebrew Voltage Controller – simple design based on LM317T regulator and small V-A display (see article in SPRAT #195, p.24).  Vin max 40V; Vout 1.2-37V; Iout up to 1.5A.
  • Homebrew single paddle key, made with popsicle stick inside a plastic screw-top vial.

I chose a whip- versus a wire-based antenna system because I anticipated setups on hotel balconies, beaches or in city parks, not “off in the woods”.  Wire antennas are certainly more portable and could be taken in carry-on without worry, but might be more noticeable during setups in city parks.  Wire antennas are also not much good on beaches or balconies (without distant anchor points).  I wanted to be less conspicuous, and didn’t need to worry about weight.

Air travel with radio gear

I put all my QRP gear and antenna in my checked bag and had no trouble anywhere.  I added a note in English and Portuguese stating that this was amateur radio gear for hobby use, and included a copy of my Canadian licence. I probably could have taken the works in carry-on, but I was a bit uncertain about the metal monopod and whip (might be perceived as a weapon) so I just checked it all.

1. Lisbon Old Town

Due to a *two-day* travel disruption on the way to Portugal (thanks to Air Canada at Toronto Pearson airport; another story), we only had one night in Lisbon. Our hotel was a four-storey concrete and steel building in a narrow street. Our 3rd storey room had two little balconies about 3 m apart, with metal rails. To test the waters, I mounted the monopod and whip on one balcony and tied off the radial to the other balcony. The antenna impedance match was fine but, either due to band conditions, night time, or metal in the buildings, all three bands (15-10 m) were dead. Not a single signal; not even the ghoulish drone of digital signals; a total bust. Not a great start, but things improved later – read on!

Figure 2- Tram on steep street in Lisbon Old Town, close to our hotel

2. Faro (Algarve Region)

We travelled by wonderful inter-city Portuguese train to Faro in the Algarve.  Faro is a hub city in this sun-drenched and slow-moving southern region of Portugal; a region where everyone seems to be in second gear, and quite content there. Being a coastal city, I had hopes of good propagation.  Our schedule meant I could only play radio at our hotel late one afternoon. I set up in a quiet corner of a concrete-walled, 2nd storey courtyard with an open roof.  The top of the whip extended ~1 m above the concrete wall, but the radial was deployed entirely within the courtyard.  An improvement on the air – I could hear a number of stations, mainly on 15 m, and worked LY2NK (Lithuania, 3,119 km).  I was amazed at what 1.7 W and a whip antenna with a single raised radial could do!

Figure 3 – Walking street in Faro, 5 min from our hotel.
Figure 4 – Boats at Ilha da Culatra, on day trip out of Faro

3. Porto and Foz do Duoro (“mouth of the Duoro”)

We travelled on a delightful high-speed train (complete with coffee and snacks trolley down the aisle!) up to Porto in the north of Portugal.  Porto has a much different vibe than the Algarve.  A more working-class, energetic, commercial feel, and steeped in the wine- and port-making industry along the picturesque Duoro River. The Duoro Valley is a huge viticulture region and, yes, they still stomp grapes with bare feet on harvest day (don’t worry – in the making of port, fortification with 60% alcohol (aguardente) abruptly stops sugar fermentation and kills every living microbe in the batch!).

One afternoon, we took a clattering electric tram from downtown Porto west to Foz do Duoro, a seaport town 6 km away where the Duoro R. empties into the Atlantic.  After an espresso in an outdoor café, I set up the radio in a city park adjacent to the ocean – monopod lashed to a park bench and a radial tied off to a palm tree.  Figure 5 shows my park bench set up with a sea wall and Atlantic in the distance.  In QRP radio, as in real estate, “localização, localização, localização”!  Conditions were great here and I worked these stations on 15 m:  TM56JO (France; 1,087 km); HA0DD (Hungary; 2,476 km); OU5U (Denmark; 2,146 km); LY2PX (Lithuania, 2,903 km); and 9A2N (Croatia, 2,119 km).  Very exciting! And, again, passers-by  took no notice.

Figure 5 – Radio set up on park bench, Foz do Duoro, Portugal. View west to Atlantic Ocean in distance.
Figure 6 – Detail of my radio set up. Clockwise from L to R: paddle key in clear plastic vial; blue floss container with volume control for ear buds; ATS-V5 rig (green cover) in bottom of Altoids tin; oltage controller in bright blue Altoids tin; Li-ion battery pack (black rectangle); common mode choke (red sleeve); resistive SWR bridge (silver top with LED). Zippered back for this gear is immediately to right. The whip collapses to about 14 in and fits inside the camera monopod for transport.

4. Madeira

Air travel is fairly cheap within Portugal, so we detoured to Madeira, an autonomous Portuguese island in the Atlantic ocean ~1,000 km southwest of Lisbon.  The main city (Funchal) is about even with Casablanca on the Moroccan coast.  Madeira is a very rugged volcanic island with its highest point (Pico Ruivo) 1,862 m (6,109 ft) above sea level.  We were based in Funchal and toured around to see the sweeping vistas, mountain-scapes, and steep coastal cliffs.

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.

On a POTA Mission with the RGO One!

7 Comments

On Thursday, June 6, 2024, I had two missions:

  1. To help fellow volunteers at the Asheville Radio Museum assemble shelving.
  2. To fit in a POTA activation over lunch.

I started out the day pretty early at the QTH sorting out a few chores, then I made my way to the museum around 9:30.

The Asheville Radio Museum

I’m a member and volunteer of the Asheville Radio Museum, a small – but brilliantly curated – museum on the campus of Asheville-Buncombe Technical Community College.

That Thursday morning, we organized a shelf-building party to assemble a shipment of new shelves we’re going to use to house our collection in a new space A-B Tech has given us on the third floor of the Elm building.

We’re super excited about the new space not only because it’s much larger, but there’s even a dedicated workbench where we can invite students and guests to learn some soldering and repair skills.

If you’re ever in the Asheville, North Carolina area, I’d strongly encourage you to check out the Asheville Radio Museum. Check our website for directions and hours.

We ended up working on the shelves for a couple of hours, and once assembled, I decided to grab lunch at Bridge & Tunnel Coffee in the Coman Student Activity Center next door. The food and coffee were absolutely amazing. A-B Tech students are so lucky to have a café of this caliber on campus!

I spent more time hanging with my friends at lunch than I had planned. No regrets there.

I knew there was still plenty of time to make my way to the Vance Historic Birthplace and fit in a POTA activation! Twenty minutes of driving later, and I was pulling into the Vance parking lot.

Zebulon B. Vance Birthplace (US-6856)

As I made my way around the visitor’s center, I was very pleased to see that the picnic shelter was unoccupied. School was still in session for many districts in the area and field trips tend to take place near the end of the term. Had there been a school group at this small historic site, I would have gone elsewhere to activate so as not to disturb them.

The weather was pretty amazing – the perfect day to be outdoors playing radio.

Speaking of radio, I brought a special one with me that day.

The Mission RGO One

As I mention in my activation video below, I receive more questions about this radio than any others I take to the field. Some have seen it in previous activation videos, and many see it in my QRPer.com banner rotation.

Typically, I’ll get a message with the following question, “Thomas, what is that cool radio with the white faceplate I see in the banner on QRPer?”

It’s no wonder I get a lot of questions about it. The Mission RGO One is a very low-production run modular transceiver – the creation of Boris Sapundzhiev (LZ2JR).

Boris produces the Mission RGO One in small batches at his facility in Bulgaria. This is very much a cottage industry radio – one you won’t find in many shacks or on Field Day because there just aren’t a lot out there (compared with Yaesu, Elecraft, Icom, etc.).

I’m a massive fan of the RGO One. So much so, that if I had to pare down my radio collection to only two HF transceivers, the RGO One would be one of those two.

I love the RGO One’s legacy design and the fact it’s a down-conversion superhet receiver with 9MHz IF. The receiver is absolutely amazing.

You don’t see the RGO One in many of my POTA videos mainly because I tend to use my smaller, portable radios in the field. That said, the RGO One was designed with field operating in mind – it’s a very capable radio and lightweight compared to other tabletop radios.

The RGO One is my main HF radio in the shack, so it actually gets heavy use. If I’ve ever hunted you at the QTH while you were activating a park or summit, it was likely with the Mission RGO One.

As I mention in the video, I will plan to make a “Getting To Know You” video with the RGO One in the near future, so I’ll speak a bit more about it then.

In the meantime, you can read my full review of the Mission RGO on The SWLing Post and check out more about any upcoming production runs on Boris’ website.

Setting Up

I decided to deploy my KM4CFT EFHW kit that I trimmed for 30 meters with a 40-meter extension. This antenna is brilliant because it resonates on 30 and 17 meters as a 30-meter EFHW, then if you link the 40-meter extension, it’ll give you 40, 20, 15, and 10 meters. That’s six bands on one antenna without the need for an ATU.

Next, I paired my Begali Traveler paddles with the RGO One.

Although the RGO One has a maximum output power of 50 or 55 watts, I had it set to my standard 5 watts QRP.

On The Air

Being in the early afternoon, I decided to hop on 20 meters first, as I assumed it might be one of the more productive bands. Conditions – as we all know – have been quite rough as of late, so I tend to start my activation on the band where I think I’ll accumulate the most contacts.

M0VKR’s Lewesdon Hill SOTA activation with the Elecraft KH1

3 Comments

Many thanks to Lee (M0VKR) who shares the following field report and video:

Activating Lewesdon Hill with the Elecraft KH1

by Lee (M0VKR)

After taking a day off from work my wife Joanne and I pondered about what we could do. “Shall we go over to Dorset to that hill you have spoken about and take your new radio?” There is no need to ask me twice to get outside and activate so we were quickly packed.

The KH1 came as the Edgewood package, so everything is contained in its own pack, ready for moments just like this. I grabbed it off the shelf in the shack, along with a KX3 as backup.

Within 10 minutes we had our labradors Toby and Konnie in the car and set off on a new CW ham radio adventure to activate Lewesdon Hill in Dorset for a SOTA activation. It was mid-morning by this point and things looked promising for a perfect day of outdoor radio operation.

With my Elecraft KH1 and KX3 as a backup snugly packed, along with my trusty home brew antennas, we embarked on the journey. The drive was scenic, with the rolling hills of the Dorset countryside providing a beautiful backdrop, Traffic was light too – Perfect.

After 45 minutes or so we arrived at the base of Lewesdon Hill. I took a moment to appreciate the tranquility of the area, breathing in the fresh air. The only downside was no nearby carpark, so we parked the car in a layby making sure it wasn’t going to be in the way of any farm traffic.

Finding the right spot to set up was the first small challenge.

Lewesdon Hill is only 279 meters (915 feet) to the summit, not exactly a mountain but it is the highest point in Dorset. We set off up the concrete driveway to a local farm, then turned right through a gateway and began ascending. The ascent is marked as a footpath and is pretty much through woodland until you get to the summit. It is a relatively steep climb, and we stopped every so often to take in the expanding view of the countryside through the trees.

Joanne had completed a 10K run a few days before so was happy to stretch her legs.

We arrived at the summit in good time. I needed a location with good elevation and a clear view to maximize my reach.

After a brief walk 1KM’ish, Joanne found the perfect spot—a clearing with a panoramic view of the surrounding area and a fallen tree which made the perfect workstation. I could already feel the anticipation building as I began unpacking my gear.

Setting up the antenna is always a mix of art and science, but mostly just plain luck. Today, I was using my favourite home brew random wire, which had served me well in previous activations. I found a stone to act as a weight and tossed the wire into a tree on the first shot and with a few quick adjustments, it was up and ready. Next came the radios.

The Elecraft KH1 and KX3 are compact yet powerful, ideal for portable operations like this. Because the KH1 had been configured already at home and previous activations, I hit the tune button. It tuned the random wire within a second or so and I double checked the keyer speed and set it to 16 WPM. Luckily, there was good phone service, so I sent out a spot on the SOTA website and I was ready to start.

The band conditions were not exactly favourable, however the clear blue skies hinted at a good run. I powered up the KH1 and began calling CQ. A station in Northern Ireland came back instantly and exploded out of the speaker, at a lovely cadence. One by one, contacts started rolling in. Each successful connection was a small victory, a testament to the power of CW communication and the effectiveness of my setup and of course the superb performance of the Elecraft KH1.

The weather was kind, with a gentle breeze keeping things cool. Throughout the activation, I logged 4 contacts, each one a story in itself. Notable among them was a contact from my good friend Steve MW0SAW from across the Bristol Channel in Wales, a testament to the reach of my modest setup. Steve and I had been in the same CWOPS class last year, so it’s always great to get him on air, even though we speak most days on the phone.

By the end of the session, I had made 4 contacts. I was really satisfied and could have sat for longer working the bands but, content, we decided to pack up and go grab some lunch from the nearby bakery in the village of Beaminster. The KH1 had performed flawlessly, and the homebrew wire antenna had once again proven its worth and overall, it had been a successful activation.

Reflecting on the day’s achievements as we hiked back down, the sun now a little higher in the sky, I couldn’t help but feel a sense of accomplishment. Having just completed a 10 week comprehensive ICR course with CW innovations and being a relatively new CW operator, I was pleased that the contacts had come back at a predictable pace. This made copying the callsigns easy. As I complete more activations, I am finding each activation is a unique experience, and today with the Elecraft KH1 was no exception. We are looking forward to the next adventure, with new challenges and new stories to tell.

Back at home, I reviewed the logs and relived the day through the video footage I had been encouraged to make by my family and friends. For those who want to see the activation in action, you can check out this video on my YouTube channel:

73 and see you on the airwaves!

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

12 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 →

From Customs to Summits: Steve’s KH1 journey into Wales and onto summits!

Many thanks to Steve (MW0SAW) who shares the following guest post:

Getting a KH1 into Wales and activating a couple of SOTA summits

by Steve (MW0SAW)

I suspect like many QRP enthusiasts, when the brochure of the KH1 surfaced on the Elecraft FTP site, and the YouTube videos appeared, I worked myself into a frenzy of radio desire for the KH1. I knew I had to have one, end of story!

I was so keen to place my order, I totally missed the small print about not being able to ship to the UK or EU because of the lack of CE certification. Or UKCA for that matter. So I placed an order online with Elecraft on 21st Oct 2023 and later it was cancelled because of my location.

Waters and Stanton used to be Elecraft dealers in the UK, in fact I got my KX2 from there a few years ago. But sadly they no longer sell Elecraft products.

Looking on the dealer list, I turned my attention to Rene and Carine at Lutz Electronics in Switzerland. Although a more expensive route to ownership, Lutz have an agreement to buy the KH1 in as a kit and assemble the unit as a service before shipping on to the customer.

So after quite a few emails back and fore with Carine, I learnt I had reserved one of a batch of 40 units destined for the Swiss border. This was around early April.

A few weeks later, on 26th April, I got the email from Lutz requesting international bank transfer payment.

It felt I was really close to getting a KH1 in my hand now, or so I thought!

2nd May I got the tracking number, and by this time I was about to pop with excitement. I was checking the tracking at almost an hourly basis by now! It arrived in London Heathrow and that’s exactly where it stopped for a week. 🙁

The unit was held by customs and I just could not find any information on who to talk to. So after a week of radio silence, a letter from UK Borderforce arrived requesting I assign myself a customs agent to get my parcel cleared. There was even a mention that the parcel would be returned or even destroyed!

Long story slightly shorter, after several more stressful days of worry, I managed to find an extremely efficient company called UK import services. It did cost me a fee, but within a couple of days of providing the invoice and seller information, they got the parcel cleared.

Saturday the 25th May 2024…the big day! I remember pacing around the house looking up the street for the postman. The parcel was handed over and I dashed inside my home to open the box.

OMG there is was, in my hands, wow so small and such a thing of radio QRP beauty!

My friend Lee (M0VKR) also received his that morning and immediately packed his car to head for his nearest SOTA summit: High Willhays (G/DC-001).

Conditions had been terrible with the solar activity, but I managed to get my first QSO with Lee on 40m, in fact KH1 to KH1. I did have to plug it into my home QTH ZS6BKW to make the trip.

So two days later, I was presented with the opportunity and decided to grab a local summit: Craig yr Allt (GW/SW-037).

Conditions weren’t great but I wasn’t put off trying. I managed to qualify with the whip antenna and 17m came up with the goods to qualify.

I was struck by how small and light the unit is, and just how quick the station is to deploy.

In the distance the Bristol Channel and the islands of Flat Holm and Steep Holm. Flat Holm being the place where Marconi sent his first oversea radio signal to Lavernock Point.

The following weekend I took the KH1 out to the SOTA summit of Mynydd Y Glyn (GW/SW-027). Another day of terrible radio propagation. This time I deployed one of my MW0SAW EFHW antennas and the Bamatech TP-III key.

So despite the difficulties getting the radio, and despite the poor radio conditions it was great to be out with the KH1.

I absolutely love it.

It now goes everywhere with me, it’s insane how quick you can deploy it. Even managed to chase a German SOTA station from the office carpark, on 30m with the standard whip and 13 foot counterpoise!!

73 from Wales.

Joe’s Adirondack Adventure: POTA activations in the Independence River Wilderness

1 Comment

Many thanks to Joe (N0LSD) who shares the following guest post:

Independence River Wilderness – Adirondacks, NY

by Joe (N0LSD)

A recent family engagement offered me the perfect opportunity to travel to a part of my state I rarely get the chance to visit.

This trip would be a single over-nighter, but allow for the activation of three POTA entities by hitting two different locations.  One stop would be a two-fer, while the other location would be a single-park activation.  Additionally, this trip would offer the potential for ‘late-shift’ contacts:  always a nice feature of overnight activations.

The Planning

In northern New York lies a vast, 6-million acre (over 2.4 million hectare) area that has been set-aside in the State’s constitution as protected land, and half of this area contains wildernesses that are meant to be kept ‘forever wild’.  This area, known as the Adirondack State Park, is fully 20% of the land area of the state of New York, and constitutes the largest area of state-protected land in the United States.

By way of comparison, one could fit Yellowstone, Grand Canyon, Yosemite, Everglades, and Great Smoky National Parks all within the Adirondack State Park boundary – at the same time.  (Wood-Tikchik State Park, in Alaska, has more *contiguous* protected land, at 1.6-million acres, and the Alaskan National Wildlife Refuge is the largest Federally-protected area.)

My goal was to probe the very western edge of this region.  Situated east-southeast of the town of Lowville, NY are two parks that straddle the Blue Line, which serves as the official border of the Adirondack Park itself.

To the west is the Independence River State Forest (POTA US-5067):  this park falls outside the Blue Line.  Bordering this park to the east is Independence River Wild State Forest (POTA US-10295) – which falls within the Blue Line, and thus within the border of the Adirondack Park (POTA US-2001).

My Amateur operations over the last number of years have been primarily utilizing digital modes; however, because the destination is a place I can seldom travel, and solar activity has been unkind to the HF bands as of late, I’d not leave anything to chance.

This meant having the ability to activate these parks via SSB Voice, if necessary.  I’ve been activating parks with the TruSDX, because it is a light-weight radio.  In addition to carrying this, however, I also took the Xeigu G90, and a Bioenno 12Ah battery.  A good bit of extra weight, but it provided a bit of insurance against the possibility of a failed activation attempt.

On Arrival

In Desert Solitaire, Edward Abbey, one of the great writers of the 20th Century, wrote, “In the first place you can’t see anything from a car; you’ve got to get out of the [G.D.] contraption and walk, better yet crawl, on hands and knees, over the sandstone and through the thornbush and cactus.  When traces of blood begin to mark your trail you’ll begin to see something, maybe.  Probably not.”

Map reconnaissance showed it would probably be feasible to drive through the Independence River State Forest park on a forestry road, then hike a couple miles further into the Independence River Wild State Forest along established trails to make camp on Little Otter Lake.  This would be my overnight location and first activation opportunity – a two-fer, as this place lies entirely within the Adirondack Park border.  This would put my vehicle at a midpoint between the two POTA entities.

I tend to pour over maps in preparation for trips like this, but I know better than to trust maps implicitly, especially in the wilderness.  A couple enterprising beavers can turn a whole forest into a pond; and a stroke of a pen in a far-away capital can make a road disappear back into the woods within a few short years.  Topology rarely changes, but what is on that topology can only be trusted once one sets eyes on it.

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

12 Comments

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.
