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!

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.

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!

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

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.

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.

Xiegu X6200: Second POTA activation with rough propagation, but CW saves the day!

4 Comments

On Tuesday, June 11, 2024, I took my production run Xiegu X6200 (on loan from Radioddity) to the Blue Ridge Parkway for its first POTA activation. The activation was a success, with good band conditions on 40 and 30 meters. You can read that field report by clicking here.

Later that day, I had a second opportunity to use the X6200. My daughters were kayaking near Lake Powhatan in Pisgah National Forest, so Hazel (my activational support animal–!) and I went for a quick POTA activation.

Pisgah National Forest (US-4510)

I usually set up near the lake at Lake Powhatan, where there are picnic tables and shade. However, mobile phone reception is poor there. Since I planned to operate in single-sideband mode, I needed a way to self-spot or have a friend spot me, thus a little mobile phone reception (else, use my Garmin In-Reach).

I decided to set up at a picnic area at the top of the hill near the main parking area for the lake/beach. I’ve never seen anyone use this site before, likely because it’s not close to the lake.

The site is surrounded by trees, making it a great spot to deploy a wire antenna.

Setting up

I used my PackTenna 9:1 UNUN random wire antenna, which was already in my pack from the morning activation. It’s a good choice for the higher bands (20 and 17M) I planned to use.

I set up the PackTenna so it wouldn’t interfere with anyone walking through the site. Hazel found a sunny spot to relax.

I began by attaching the X6200 microphone and spotting myself on the SSB portion of the 20M band. I called CQ POTA for quite a while with no response.

Once again, propagation conditions were poor. Continue reading Xiegu X6200: Second POTA activation with rough propagation, but CW saves the day! →

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.

The New Xiegu X6200: First POTA activation in CW with a production unit!

14 Comments

If you’re following the new Xiegu X6200 closely, you might recall that I took a prototype version of the radio out two weeks ago for a POTA activation. Propagation was so challenging–as in, a complete radio blackout in North America due to an X-Class flare–it took about 90 minutes of calling CQ POTA to snag the ten needed for a valid park activation.

I had planned to post the activation video on YouTube, but learned shortly after the activation that this particular unit was a proper prototype instead of an early production run radio. This is a detail I misunderstood prior to the unit shipping.

I only shared the 2+ hour video to Patreon supporters, but not on my YouTube channel for this reason.

Production

This past weekend, I received a second Xiegu X6200: this time, a production run unit!

Again, this unit was supplied to me on loan by Xiegu via their distributor, Radioddity who (in the spirit of full disclosure) is also a QRPer.com sponsor and affiliate.

POTA Time!

Two days ago–Tuesday, June 11, 2024–I took the new X6200 out for a POTA activation on the Blue Ridge Parkway (US-3378).

I had a couple of hours that morning to fit in the activation, including a round trip from the QTH. The best site for a quick activation was the Folk Art Center picnic area.

Thanks to the early hour, there was no competition for picnic tables.

I decided to pair my PackTenna 9:1 End-Fed Random Wire with the X6200. This provided a chance to test the ATU with a readily matchable antenna (in the future, I’ll make it sweat a bit more by using a transformerless random wire antenna).

This production run X6200 has the same firmware (version 1.0) as the prototype, but the hardware has received noticeable updates. I spotted two changes–one cosmetic and one that had a positive impact on performance–almost immediately.

In the activation video below, you’ll see that I spent a few minutes doing an overview of the X6200.

One of the first things I did was set up the X6200 for CW Message memory operation. I demonstrated (after a bit of head-scratching) how to input the CW message using the X6200’s built-in on-screen keyboard. (If the CW Message Memories confuse you, check out the short primer in my previous post).

On The Air

The last time I hopped on the air with the X6200, it was proper work making any contacts. It was a struggle and it wasn’t the X6200’s fault. It was our local star!

I decided to start on 40 meters since it was still mid-morning. After calling “QRL?” and hearing no reply, I pressed the second CW message memory button where I loaded “CQ POTA DE K4SWL” and the radio started transmitting.

The POTA Babe Reaches the Halfway Mark!

2 Comments

by Teri (KO4WFP)

It is said that all good things must come to an end and a POTA trip is no exception. Packing up camp at Reed Bingham State Park the morning of June 3rd was an easy endeavor.  Daisy and I were soon headed toward Savannah with a POTA planned along the way at Alapaha River Wildlife Management Area (US-7881). We passed through the communities of Tifton and Ocilla, Georgia.

As one travels through Georgia, you see a variety of crops along the road – cotton, peanuts, corn, pecans, blueberries, soybeans, etc. – as well as cattle in fields and poultry houses. As I worked my way toward Alapaha River Wildlife Management Area (WMA), I came across a processing plant for peanuts in Tifton, Georgia.

Peanuts are big business in Georgia. According to the Georgia Peanut Commission, the state of Georgia produces 52% of the peanuts grown in the United States which translated to 1.45 million tons in 2022. That is a boatload of peanuts!

Peanuts are planted April through June and then harvested about five months later in the fall. One fact I did not know is there is a “peanut belt” in Georgia, an area south of the fall line but omitting the coastal counties, where peanuts are planted in the state. I was driving inside this belt.

Nuts aside, it wasn’t long before Daisy and I arrived at Alapaha River WMA. This WMA opened in 2016 and contains nearly 7,000 acres. According to a Georgia DNR article, the site has an estimated 2,000 gopher tortoises, the most for any state-owned tract of land in Georgia. This is not surprising given the density of sandhills on the property, a habitat in which gopher tortoises thrive.

The dirt road into the property was nicely groomed. I drove past areas of young planted pines as well as more mature pine stands. However, neither of these areas were conducive to an activation, partially because the trees offered no shade and partially because the branches were either too low or too high for me to install my EFRW antenna.

I continued on Jacks Creek Road and headed toward a dove field (the brown area on the map down below) at the point the road dead-ends. I  figured there may be trees along the edge of the field offering what I needed. I turned left onto North Bugle Trail and, off to the right hand side, saw an area with both shade and trees I could use.

After donning my blaze orange attire and installing the Tufteln EFRW, I attached the new hitch system to the hubcap of one of Kai’s front wheels and the rope to the clip on Daisy’s harness so she could make herself at home along with me in the shade.

While checking out the shady area, I noticed several things – dandelions with their sunny, yellow faces and animal tracks in the sand. The set of tracks for deer were easy to identify. However, another set, not so. I think the second set belonged to a raccoon.

Today’s activation would be short as I had a three-hour drive ahead of me and needed to be home in time for my son’s evening driving class. (Yes, we’ve reached that stage of life in the POTA Babe household.) In 45 minutes, I logged 19 contacts including one park-to-park with Charles AB9CA at US-2275 and a QSO with Ronald N7WPO in Washington state! That QSO on 5 watts and a wire is part of the magic I mentioned near the end of my previous article.

During the activation I had watched the sun creep closer and closer to Daisy and me. When the time reached 11:15 AM, we were nearly out of shade. It was time to call QRT and head home.

This overnight POTA trip turned out well. I learned more about my camping set-up and the beautiful state in which I live. I had time to do what I love – ham radio in the outdoors. And, with these three activations, I now have 30 parks toward my 60 new-to-me park activation goal for 2024!

I am halfway there.

Thank you to all of you who have supported me thus far. However, my journey is far from over and the fun will continue. Where will I activate next as I work toward 30 more new parks? Stay tuned…
