Where the Heck is the POTA Babe?

7 Comments

by Teri (KO4WFP)

Okay. Y’all haven’t heard much from me lately and may be wondering, “What the heck is the POTA Babe up to?” Actually, a lot!

Earlier this year, I asked QRPer readers for suggestions as to parks to visit for a summer POTA trip to either North Carolina and/or Virginia. I appreciate all the suggestions I received. In evaluating the time I have and that I’ll be driving by myself, I have opted to visit North Carolina. I’ll be on the road for eight days mid-July camping with Daisy. I hope to activate ten to eleven parks as well as successfully complete four SOTA activations. It is a lot to bite off but then I enjoy being challenged.

I originally planned for a twelve-day trip but decided to nix the second week near the Charlotte area due to obligations at home. I am bummed at missing out on those parks. (Thank you Bob K4RLC for the recommendations in that area.) However, now I’ll have those parks to activate on a future trip.

Preparing for this trip is no slap-dash endeavor. At least not for this POTA Babe. As I mentioned in the articles of my last trip to southwest Georgia, I am tweaking my camping equipment as well as how I organize and access those items.

An item I’ve added is a fan because camping in July might be a bit toasty, even in western North Carolina. My partner Glenn W4YES came across a helpful video on the CheapRVLiving Youtube Channel discussing USB-charged devices. The Koonie 8” rechargeable fan was mentioned. As it received favorable reviews on Amazon and I can charge it using my Jackery, it is now in my arsenal for summer camping.

I also added an ultralight shelter I may use on a summit or for POTA in general. While researching summits to activate, I came across a picture on the SOTlas website and reached out to that op as to information about the tarp he was using for shade. Patrick WW4D introduced me to Mountain Laurel Designs, a company that makes ultralight shelters (tarps and tents). They aren’t inexpensive, but then I’ve learned to purchase good quality where I can. In a shelter, good quality counts.

I purchased the Trailstar. It can be used as a tent or a shelter. Before the trip, I need to seal the seams. What I didn’t realize until the other day is that I will also need to cut the guylines as well as figure out what knots to use in securing the guylines to the stakes included. Then I have to learn how to set it up using my hiking poles. The learning never ends, does it?

I couldn’t believe how light the Trailstar is having never experienced a shelter like it. It will be a welcome addition to my SOTA backpack since it weighs hardly anything.

I’ve also undertaken re-waterproofing my tent. Sierra Designs sent me instructions and information about the products they recommend which I ordered. I thought to myself “how hard could it be to re-waterproof a tent?” Those of you who have done this know it is a time-consuming process! You have to remove the old waterproofing substances before applying the new ones. The substances used for waterproofing fabric are meant to not come off easily, especially after being on there for 30 years (the age of my tent). I’ve spent more time in the bathtub scrubbing and smelling rubbing alcohol than I care to admit. However, when this process is finished, my tent and its rainfly will be clean and good to go for another eight years or so.

I am also researching how to do a SOTA activation. I’ve found quite a few helpful videos on Youtube and plan to reference them in a future article. For my pack, I am using a Six Moons Designs ultralight pack (the Flight 30 Ultra) I purchased about four years ago. As it was not being used, I’ve been employing it as my POTA pack for several months now.  Given I’ll be hiking to activate summits, I need to rethink what I’ll take in the pack since, in addition to ham gear, I’ll need emergency supplies one should take when hiking.

While preparing for this trip, I’ve had a new addition to my shack that is sharing my focus as of late. Nearly two years ago, I ordered a Frattini Magnetic Evolution bug. I didn’t hear anything further for the longest time and figured it wouldn’t ever arrive. Then, about four weeks ago, Alberto Frattini sent me an email the key was ready and, oh by the way, was I still interested in it? You bet I was! “The Frattini” (as I call it) is now in my shack and I am resuming my pursuit of the Straight Key Century Club’s (SKCC) Triple Key Award. (When I’m not scrubbing the tent, mind you.) My fist is a work in progress but what a great challenge!

my Frattini Magnetic Evolution bug
Hummer on the Frattini plate – a nice touch given my POTA Babe logo also has a hummingbird on it

My goal is to run at three speeds eventually – 16, 20, and 25 wpm. Right now I am concentrating on 16 wpm as that is a good speed for SKCC QSOs. At that speed, I am more relaxed and the more relaxed I am, the better I can focus on making my characters correctly with good spacing. My goal with the Frattini is that the dits and dahs be proportional and timed well enough it doesn’t sound like I am using a bug. With continued practice off and on the air, I will eventually get there.

One thing I’ve found that helps is having either Word List Trainer up and running or my Morserino in the shack. Just like a choir conductor will play a note on a pitch pipe for a choir, I’ll play the letter “o” at 16 wpm to get that dah cadence in my head before I get on the air. Eventually, I’ll fall into that rhythm naturally at that speed but in the meantime, I find that trick extremely helpful with my timing of the dahs.

If you’d like to hear my bug fist (a work in progress, mind you), click on the video link here to access it on Youtube.  Also, if you’d like to follow my progress on earning bug QSOs for the Triple Key award, check out the goals section on my QRZ page.

Well, there you have it – my ham radio related doings since my southwest Georgia POTA trip. For those interested in hunting me while I’m in North Carolina, I will not release my itinerary in advance for safety reasons. However, Glenn or I will schedule my activations each morning so keep an eye out on the POTA and SOTA Watch pages beginning July 14 if you are keen to work me and support the trip.

I am a little nervous about the trip.  I’m going to be out of my comfort zone and sure to make mistakes. However, this is how we learn – making mistakes. This is a part of ham radio and such a trip – the unknown! Who knows what I’ll learn and discover along the way. I hope to work many of you that week and look forward to sharing with you those adventures on QRPer.com after my return. But before I leave next Sunday, I plan a POTA activation Monday, July 8 to get my head back in the game. What park will I pick? Stay tuned…

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

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 →

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!

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 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.

UK POTA Rain and Shine

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 →

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.

QRP in Thailand: Drew’s Journey to Get Licensed and On the Air

1 Comment

Many thanks to Drew (W8MHV) who shares the following guest post:

QRP in Thailand

by Drew (W8MHV)

I travel to Southeast Asia each year and usually have a few weeks in Thailand, but this year we planned on a longer stay. My XYL (N8MHV) has family in Thailand and we own a condo in downtown Bangkok. This year I was intent on getting my Thai ham license; I have never previously been licensed there.

You might be surprised to know that Thailand doesn’t make it easy for a casual American visitor to be awarded a ham license, even though the country has a bilateral agreement with the US on licensing.

For starters, you must have a visa for a long stay. A visitor can stay in Thailand for 30 days without a visa, and I have always limited my stay accordingly. But this year we stayed for of two months and getting a visa was necessary. That wasn’t especially difficult once my Thai-speaking wife helped figure out the necessary paperwork. In Thailand my wife’s calls to government offices led to a contact with the Radio Amateur Society of Thailand (RAST). Once I joined the organization, they helped push through the application and award of the license.

The RAST Secretary whose nickname is Top was a very great help. I felt like this was a big achievement as there are fewer than 1,000 ham licensees with HF privileges in a country of about 70-million.

QRP operating from anywhere in Southeast Asia requires great patience. This is because if you operate in a DX location, then everyone you work is DX to you, as by definition there are few if any local stations!

I brought my newly-acquired Elecraft KH1 for on-air use. Its tiny size made it easy to pack for overseas travel. It worked flawlessly, but the built-in whip antenna was far less useful than a 20.5 foot random wire with counterpoise I included in my kit.

Operating the KH1 from my condo.

In my 12th floor condo noise levels were terrible—typically S7, but at the top of the building on the 24th floor there is a garden where the noise levels were a manageable S3. See the photo above.

I also operated from an island in the Gulf of Thailand at a resort and noise levels there were even more quiet, as you would expect. Also, this was a comfortable operating location as the photo shows.

During my stay propagation conditions were poor mostly and I struggled to work any stations. A typical example is my final night in Bangkok I repeatedly called a station in Hong Kong whose signal was about S5, but I never got an answer. It was about the closest station I heard, but the signal path was about the same as the distance between New York City and Caracas, Venezuela.

I have operated from other Asian locations with QRP radios many times and the results have varied, chiefly depending on the kinds of antenna I could erect. Sometimes it has been lonely, other times control of a big pileup has been a challenge.

Finally, a few thoughts about the KH1.

It is an unparalleled performer for its size. It has most features you would want and its ergonomics are good. The weakest point was the paddle set, and since returning, I have replaced them with the KM4CFT aftermarket set. That said, in my travel to Thailand next year, I think I will take a KX2. It offers a few more features at a small increase in packing size.

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 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.

QSO Map for Alapha River WMA Activation

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…

From Hamvention to History: A POTA Excursion with friends through Indiana’s Past

1 Comment

You might recall that my friends Eric (WD8RIF), Miles (KD8KNC), Brian (K3ES), Kyle (AA0Z), Charlie (NJ7V), and Joshua (N5FY) all played hooky on the final day of the 2024 Hamvention (Sunday, May 19) and instead activated a couple of POTA sites.

I wrote a short field report about our first activation at Pater State Wildlife Area (US-9492). It was a lot of fun despite the rough bands.

Our next stop was Whitewater Canal State Historic Site in Metamora, Indiana, about an hour’s drive from the first park.

Only four of us continued to the next park; Kyle and Charlie needed to head to the airport, and Joshua needed to start his drive back to Georgia.

Whitewater Canal State Historic Site (US-6977)

I was excited about visiting Whitewater Canal because it would be my first official POTA activation in Indiana.

We arrived around 1:00 PM and opted to grab lunch at a nearby pizzeria before activating.

Around 2:00 PM, we grabbed our gear from the car and walked across the road to the park grounds.

The Whitewater Canal State Historic Site offers a glimpse into the 19th-century canal era.

Built between 1836 and 1847, the Whitewater Canal was a 76-mile waterway that connected the Ohio River to Hagerstown, facilitating the transport of goods and agricultural products.

This engineering feat played a vital role in the economic development of the region, contributing to the growth of towns and industries along its path.

Today, the preserved section of the canal, along with the historic grist mill and other structures, stands as a testament to Indiana’s rich industrial and transportation heritage.

I’ve always been fond of railroads and canals, so this site was brilliant as it featured both running parallel to each other!

Eric, Brian, and I (Miles didn’t activate) were careful to set up within the actual park boundaries.

In this case, it was a little difficult to determine the exact boundaries because the town and park blend together.

I used the Parceled app on my phone to confirm our location.

Eric set up his Elecraft KH1 station at a picnic table under a large tree.

Brian set up his KX2 on a covered bench next to Eric, using his Elecraft AX1 antenna mounted on a clamp secured to the bench.

Brian’s site was super stealthy behind the sign–since he operated with earphones, you couldn’t hear him and barely could see him!

Can you spot K3ES in this photo?

I wanted to put some space between my station and theirs, so I set up under the shade of a tree (it was blazing hot that Sunday) and deployed my Helinox camping chair.

Local ducks enjoying the shade–I picked a different tree.

I then deployed my Chelegance MC-750 vertical for 20-meter operation since Brian and Eric were on other bands.

I connected the MC-750 to my Elecraft KX2, which I mounted on my kneeboard, and was ready to play radio! My hope was that band conditions would be decent. Continue reading From Hamvention to History: A POTA Excursion with friends through Indiana’s Past →
