Getting To Know You Series: The Ten-Tec Argonaut V (Model 516) – My thoughts, notes, and a POTA activation!

I’m very fortunate in that over the past few years I’ve accumulated a number of QRP radios that I use in rotation when I do park and summit activations.

I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.

I’ve written formal reviews about most of the field radios in my collection over the years. In those reviews, I try to take a wide angle view of a radio–I try to see how it might appeal to a number of types of operators: field operators, DXers, summit activators, contesters, rag-chewers, casual operators, SWLs, travelers, outdoor adventurers, mobile operators, etc. I highlight the pros and cons, but I don’t focus on my own particular take because, again, my style of operating might not match that of readers. I try to present the full picture as clearly as I can and let the reader decide.

On that note, I thought it might be fun to take a radio out for a field activation and spend a bit of time explaining why I enjoy using it and why it’s a part of my permanent field radio collection. Instead of taking that wide-angle view of a radio like I do in magazine reviews, I share my own personal thoughts based on long-term experience.

Each new video in the Getting To Know You series will highlight one of the field radios from my field radio collection.  I’ll spend time in each video explaining what I personally appreciate about each radio, then we’ll do a park or summit activation with the radio.

I’ll release these every few weeks or so–when the notion strikes me.  They will not be on a regular schedule, but I hope to include each of my radios in this series over the the next year.

The Ten-Tec Argonaut V

The third radio in the Getting To Know You series is my Ten-Tec Argonaut V (Model 516).

I’ve always been a big fan of Ten-Tec products because I love their focus on quality, high-performance receivers, and benchmark audio fidelity.

Ten-Tec has produced some impressive radios over the years and was a trail-blazer in the world of QRP with their Power Mites and original analog Argonaut series (check out these and more T-T radios here).

When Ten-Tec manufacturing was located in Sevierville, Tennessee, I knew many of the employees of the company and even did Alpha and Beta testing for their QRP radios like the Patriot, Rebel, and Argonaut VI.

I love the ergonomics and simple front panel design of the Argo V.

I purchased my Argonaut V used in 2021 when I saw it for sale on QTH.com. The price was right and, frankly, I wanted a Ten-Tec radio back in my life.

In the activation video (below) I’ll speak to all of the reasons I love the Argonaut V, why I think it’s so unique, and why I’ve no intention of ever selling it. Then, we’ll perform a POTA activation with it.

Keep in mind that my perspective will primarily focus on HF CW operating–I don’t actually own a microphone for the Argonaut V, but I do plan to at some point.

Lake James State Park (K-2739)

On Sunday, August 13, 2023, I made a detour to Lake James State Park en route to visit my parents in Hickory, NC. As I’ve mentioned many times before, Lake James is one of the easiest parks I can hit in my travels and it’s open every day of the week–in the summer, it’s also open quite late which is a bonus.

The only negative with evening activations at Lake James is fighting the mozzies–they can be persistent!

I picked out a picnic table close to the car and pulled the Argonaut V from my Husky latching box.

I then immediately deployed my MW0SAW 40 meter End-Fed Half-Wave antenna. Since the Argonaut V doesn’t have an internal ATU, the EFHW would give me the flexibility to operate on 40, 20, 15, and 10 meters natively.

Of course, it was in the early evening, so I only intended to hop on 40 meters, but I had the option to move up the band if needed.

After deploying my antenna, I recorded the “Getting To Know You” portion of the activation video–I’d encourage you to check that out below!

Time to hop on the air! Continue reading Getting To Know You Series: The Ten-Tec Argonaut V (Model 516) – My thoughts, notes, and a POTA activation!

Alan’s Long Beach Island Radioactive Vacation!

Radioactive vacation on LBI (Long Beach Island)

by Alan (W2AEW)

We look forward every August to our much needed 2 week vacation “down the shore” as we say here in New Jersey.  Our vacation spot of choice is Long Beach Island, one of the barrier islands on the Jersey coast. This is an 18 mile long island that hugs the Atlantic coast of southern NJ, just north of Atlantic City.  The part of the island we love to stay in is called Surf City.  The Surf City area has been continually populated since 1690, although the town of Surf City was officially established in the late 1800s.

The XYL and I are both pretty fair skinned, so laying out on the beautiful LBI beaches everyday isn’t really our thing.

So, the house we rent is actually on the bay side, facing west, overlooking the Manahawkin Bay.  We enjoy sitting back and watching (and occasionally participating in) the wide variety of activities on the bay – the fishing & crabbing, the power boats, personal watercraft, paddle boarding, sailing, etc. Our favorite though, and the thing that keeps us coming back every year, are the awesome sunsets over the bay.

Of course, we always need to find a house that is pet friendly. Sophie loves LBI also, especially the long walks around town with the sea breeze.  Here she is waiting at the top of the stairs – hoping to hear the magical word….  “walk”…

LBI is certainly a family and pet friendly place.  Even the local Dunkin Donuts has a wall dedicated to the local pets:

I certainly planned to do a fair amount of QRP operating while on vacation – both from the rental house as well as POTA from the nearby parks (more about this soon).  But lest you think this was purely a radioactive vacation, let me reassure you that we did a lot of “normal” vacation activities too.

Like most, a lot of vacation is about relaxing, eating, other stress relieving activities, eating, shopping, and of course, eating…  Breakfasts were typically some homebaked muffins, or even some fresh biscuits from the oven with some great Black Bear Jam – a gift from a good friend in NC.  Yummy!

The main meals were a mix of good ‘ole home cooking and some great local cuisine, including great Jersey pizza from Panzone’s,  fresh local seafood from Mud City Crab House and   Pinky Shrimp’s Seafood Company.  Of course, no trip to LBI is complete without getting some of the best burgers in the state from Woodies Drive In in Ship Bottom, right next to Flamingo Mini-Golf – one of *many* mini-golf places on the island.  I’ve personally seen Ray Romano golfing at Flamingo with his family.

I did manage to do some other “normal” vacation activities besides radio…  A couple of relaxing afternoons on the beach, completed a 1000 pc jigsaw puzzle, read two James Patterson novels, lounging on the decks overlooking the bay and lots of strolls with the XYL and the dog.

But who’s kidding who, this is a QRP blog right!  Let’s get radioactive!

One of the first tasks after unpacking was setting up the antenna at the rental house.  The location was great, right next to the bay!  I strapped my slip-fit military fiberglass poles to the corner post of the 2nd floor deck, which made a great support for the 40m EFHW wire.  This is the same UNUN & antenna that I featured in a “build” video a few years ago.

N3HXZ: SOTA and POTA in the San Juan Islands!

Many thanks to Dale (N3HXZ) who shares the following guest post:


SOTA and POTA in the San Juan Islands

by Dale Ostergaard (N3HXZ)

My wife and I like to take educational tour vacations from time to time. The outfit we mostly use is Road Scholar.

The tours are geared around education and immersion in local cultures and experiences. In addition, you meet a lot of like-minded people on the tour and make new friends.  Last summer we wanted to take a vacation to the pacific northwest. We had never been there and came across a tour through the San Juan Islands. The islands are located north of Seattle and east of Vancouver. Touring the islands is made easy on a guided tour as they arrange for all transportation between islands and on land.

Washington State has an excellent network of ferries serving the island which makes for easy connections to the islands.

After we booked the vacation I began wondering if there were SOTA and POTA opportunities on the islands. I quickly looked up sites on the SOTA Goat app and the POTA website.  Low and behold there was a treasure trove of parks and summits!

SOTA Map

Realizing the opportunity, I cross checked our itinerary with the parks and summits. The difficulty of course is that when you are on a guided tour, you have very little flexibility in the schedule, let alone transportation to go off on your own. After researching, I found 4 opportunities that included 3 parks and 1 summit. The parks were K-0061 San Juan National Historic Park, K-3223 Lime Kiln Point State Park, both on the island of San Juan, and K-3232 Moran State Park and summit W7W/RS-065 Mount Constitution on Orcas Island. The Summit lies inside the park so I had the opportunity to grab both with 1 activation. Continue reading N3HXZ: SOTA and POTA in the San Juan Islands!

Pairing the Yaesu FT-817ND and Chelegance MC-750 at South Mountains State Park

After completing a lively little POTA activation at Lake James State Park (K-2723) and then Table Rock Fish Hatchery (K-8012) on the morning of Monday, July 31, 2023, I decided to squeeze in one more POTA adventure on what became a mini rove.

Since nearby Tuttle Educational State Forest is closed on Mondays in the summer, I chose to visit South Mountains State Park (K-2753) instead–it was only a few minutes further afield than Tuttle.

After leaving Table Rock, I picked up a quick lunch in Morganton and drove to the main entrance of South Mountains and set up at the equestrian picnic area.

South Mountains State Park (K-2753)

 

The weather that day was beautiful and so was the drive.

I decided to deploy my Chelegance MC-750 this time, just to shake things up a bit. If you know me, when I do little roves like this, I typically like to use different radios and/or antennas at each site.

I paired the MC-750 with my Yaesu FT-817ND. My reasoning for picking the ‘817 was because I could use the SO-239 connection on the back of the radio. The new cable assembly/feedline I was using had PL-259s on each end.

Speaking of the new assembly, at the Dayton Hamvention this year, I popped by the ABR Industries booth and Chuck gave me (full disclosure–at no cost to me) a new product to test in the field: a 20 foot PL-259 to PL-259 assembly made with their ABR240-UF cable and with 5 in-line ferrites. What makes this cable unique is that it sports a bright orange flexible webbed jacketing which makes it very easy to see on the ground.

They’ve been informally calling it their “POTA cable.” I immediately knew why this would appeal to POTA ops: one of my constant fears is that someone will unknowingly trip on my feedline while I’m in the middle of an activation. Black coax cable on the ground is very difficult to see (I’ve even tripped on my own lines)–this high visibility jacketing makes cable very conspicuous. Just check out the photos above.

Unveiling Poland: POTA, SOTA, and a Glimpse into History – Part 1: The Rover Award

by Thomas (DM1TBE as SP/M0KEU/P)

Just like last year, my family and I combined a visit to my parents near Berlin, Germany in the summer with some extra days in the region. As in last year, we went to Łagów (German: Lagow) in Poland.  The reasons we chose Łagów again, was a lovely holiday house, directly on a beautiful lake with a beach – all not too far away from Germany – and the good memories we had from our previous stay.

There is also a SOTA summit, which was only activated once in the 5 years when we visited the area last year. As I started with POTA this year and there are also a couple of POTA spots around, I thought it would be worth another visit.

The area around Łagów has been populated since the Bronze Age, i.e. >1000 BC. In 1251, the area came under German rule and the first mention of the town was in 1299. In the 14th century, the Knights Hospitaller built a castle that exists to this date. For the year 1367, it is documented that the convent of Lagow consisted of seven knights and one priest of the order.

At the foot of the fortress, a settlement for craftsmen and servants emerged, secured by defensive walls and two gates.

Gate in the middle

It is obvious that the builders of the gates did not have modern cars in mind when planing the size of the gates.

During the Thirty Years’ War, one of the longest and most destructive conflicts in European history, Lagow was captured and destroyed by the Swedes in 1640. The hand drawn map below from 1662 already shows Lagow.

During the fighting at the end of World War II in the spring of 1945, the castle and the village did not suffer mayor damages. After the war’s end in 1945, Lagow was placed under Polish administration, and Polish migrants settled in the area. The local Polish authorities expelled the native German residents who had not fled. The spelling of the town’s name was changed to Łagów.

Germany lost large parts of its territory as a consequence of the wars it has started after both major wars of the last century. Lagow was part of the lost territory depicted in the green area below.

The territorial gain probably wasn’t something Poland was very happy about, as the Soviet Union annexed a significant portion of Eastern Poland at the same time and incorporated the previously Polish soil mainly into the Soviet Union republics of Ukraine and Belarus. Consequently, the country experienced an effective westward shift.

Red: Pre-war Poland, Pink: Post-war Poland

Over a long time, expelled Germans were very vocal about claims to return the area to Germany and yet rather quiet about their share in the terrible events that unfolded between 1933 and 1945. Therefore, Germany’s eastern border was not recognized until 1990 by the German government. However, the issues resolved over the time and today, 33 years after the official acceptance of the border, no one I know even thinks about this as an issue any more. Additionally, the Polish side appears to be more relaxed about this topic. I have seen a lot of bilingual information panels and some memorials for former German inhabitants. Nice to see the wounds heal.

The Activations

The holiday house was within the borders of a POTA park. Having a 7-year-old “early bird” son, helped my to wake up early enough to get my 100 contacts for the POTA Early Shift Activator Award.  I walked to the edge of the facility and raised my SOTABEAMS Band Hopper III linked dipole for the 20-, 30- and 40 meter bands as soon as my son woken me up and ended my activity around 9:00 local time nearly every day.

Although I had a bunch of other antennas with me, I made all activations during my journey with this antenna and an Icom IC-705.

POTA Rover Warthog Award

The density of POTA-parks is way higher in Poland than in my home region in Southern Germany.  With the help and tips from Damian (SP9LEE) I drafted a plan to activate 5 parks on a single day. Continue reading Unveiling Poland: POTA, SOTA, and a Glimpse into History – Part 1: The Rover Award

POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock!

After a fun little activation of Lake James State Park (K-2723) on the morning of Monday, July 31, 2023, I decided to fit in at least one more POTA adventure on a mini rove.

The logical choice was Table Rock Fish Hatchery since it’s such a short drive from Lake James and I always enjoy activating that particular site.

The weather that morning was beautiful and so was the drive.

Table Rock Fish Hatchery (K-8012)

I pulled into the driveway of the picnic area and–no surprise here–I had the place to myself.

In fact, according to the POTA website, I’ve activated this site 12 times and I’ve never seen another soul in the picnic area save my canine friends, park staff, and one guy who was hunting muskrats in the creek. That’s about it. Never anyone actually hanging around the picnic area.

On the drive over, I hadn’t considered what antenna or radio to use–I had a few in the back of my car.

I thought about using my Elecraft KX1, but then realized I didn’t have an extra shielded audio cable to connect to my Anker Soundcore Mini speaker nor did I have my in-line digital audio recorder. Without those things, I wouldn’t be able to make a video of the activation.

My next choice was the Yaesu FT-817ND and, in fact, it would be ideal. I was looking forward to putting the ‘817 on the air again–it’d been a couple of months!

First, though, an antenna. I pulled out the 40 M End-Fed Half-Wave Steve (MW0SAW) made for me some time ago.

This antenna has been in heavy rotation lately because it’s been in my main radio backpack as I’ve been traveling around the region.

I deployed the EFHW in short order, then hooked it up to the ‘817. Continue reading POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock!

K4RLC’s December 2022 Adventure at Stone Mountain State Park

Many thanks to Bob (K4RLC) who shares the following POTA field report from December 2022:


K4RLC’s December 2022 Adventure: Stone Mountain State Park North Carolina

by Bob (K4RLC)

As 2022 was coming to an end, I wanted one last Summits on the Air/Parks on the Air (SOTA/POTA) activation. Stone Mountain North Carolina is around 3 hours away in Northwestern North Carolina, near the Appalachian Trail and the Blue Ridge Parkway. It is a huge state park of over 14,000 acres and some wilderness areas.

A little background about this year might be helpful.

Earlier last year, both Alanna K4AAC and I were diagnosed with COVID, which turned into long serious COVID, lasting almost 3 months of acute illness, followed by several months of recovery. We are both healthcare professionals, and were vaxed and boosted and being very cautious, so it’s somewhat of a mystery what happened. One of us does have multiple medical risk factors which may have added to the complexity.

Nevertheless, we did what a lot of Americans did last winter and spring, with buying RVs and campers, and bought a Winnebago Solis camper van.

The Solis is Winnebago’s smallest van, built on a Dodge Pro Master commercial chassis. What appealed to me is that you can be completely self-sufficient, boon-docking with it. It has a 140 Watt solar panel on the roof which charges two 100 amp hour AGM batteries.

Off the grid, this powers a small refrigerator, house LED lights, water pump,  and a ceiling fan.

The Solis also has a 20-gallon propane tank, which runs a two-burner stove and a really nice furnace for cold nights. It sleeps two comfortably with a Murphy bed. Also has a sitting area with a table for dining, which can be used as a desk or an operating position for the radio.

Since getting the Solis, we have really enjoyed making trips to the beaches and mountains of Virginia,  North Carolina and South Carolina. In addition to enjoying exciting POTA/SOTA activations, we have been replenished by nature’s beauty and feeling safe in the fresh air.

Returning to my Stone Mountain adventure, I guess not many people camp in the middle of the week in December in the mountains. Initially, I was the only person in the large campgrounds. Eventually, a couple with their dog and a trailer set up at the far end. We never had any contact. It was really eerie, especially with the pea soup fog that hung around.

The most prominent feature of Stone Mountain State Park is Stone Mountain itself.

It is known as a “Dome Monadnock,” as it is a large dome of granite/quartz still standing from the Devonian Age about 400 million years ago, while the earth around it has eroded over thousands of years. (Stone Mountain Georgia is the same geologic feature). Continue reading K4RLC’s December 2022 Adventure at Stone Mountain State Park

Guest Post: A wildly successful POTA activation…on a whim!

Many thanks to Mike (KE8PTX) who shares the following field report:


One of my best POTA activations on a whim.

by Mike (KE8PTX)

Monday 8/15/2023

Doing some late afternoon POTA chasing from the back deck home QTH,  contacts on 5 watts seemed to be coming fairly easy so I started to think I should have a go at it and activate a park.

One in one hundred times I activate QRO, so I decided to take the FT-891 and blow the dust off the finals.

When filling my pack, I had a last minute change of heart and decided to stick with QRP.  Bagged up the never fail KX2 field kit and hit the road.

The park was Port Huron State Game Land (K-6762) a nearby game land with many activation spots.  As I never do look at the solar reports, this time was no different.  I feel the solar reports more times than not would keep me home. With a QRP mind set we all feel we have something to prove by just doing it.

So off to the park we go!

After a short 20 minute dive through the countryside of the Michigan thumb, I arrived at my location only to be welcomed by a flock of Michigan state birds: the mighty Mosquitoes.  I came prepared with my trusty Thermacell.  Fired it up 5 minutes before exiting the car to give it a head start.

My deployment of gear is simple and quick.  My go-to antenna is a 40m EFHW inverted V configuration running North to South.

My mid support is a modified Carbon 6 mast.

Setup time was less than two minutes and I was on the air. Continue reading Guest Post: A wildly successful POTA activation…on a whim!

Matt’s Low-Profile POTA Activation at the San Francisco Maritime National Historic Park

Many thanks to Matt (W6CSN) who shares the following post  from his blog at W6CSN.Blog:


SF Maritime NHP POTA Activation

by Matt (W6CSN)

There are several Parks On The Air eligible parks in San Francisco and the northern tip of the peninsula of the same name. One would expect that a POTA activator that calls this city home, would have logged activations from all of these parks, but so far this one has eluded me.

Muni Pier (closed) across Aquatic Cove

The San Francisco Maritime National Historic Park (K-0757) sits at the northern edge of the city, right next to the Fisherman’s Wharf area that is so popular with tourists visiting San Francisco.

NPS Map of SF Maritime NHP

The National Park encompasses an area that includes the municipal pier, aquatic cove with its small public beach, the art deco style Maritime Museum, and Hyde Street Pier with its floating collection of historic ships.

The historic ships alongside Hyde Street Pier

For various schedule and logistical reasons, K-0757 was the one park in the city that I had not yet activated. So today, when my daughter wanted to visit the ships, I made sure to have my lightweight POTA “go” pack with me in case I found an opportunity to attempt an activation.

I’d say the main attraction at Hyde Street Pier is the Balclutha, a steel hulled, square rigged, cargo ship built near Glasgow, Scotland and launched in 1886.

Balclutha – a survivor from the Age of Sail

Balclutha is continually undergoing restoration and maintenance by the Park Service and skilled volunteers. Her many careers on the world’s oceans are documented with numerous interpretive stations and exhibits, both topside and below decks.

We wrapped up our tour of the vessels on the pier by exploring C.A. Thayer, a 219 foot long sailing schooner built in 1895 near Eureka, California to serve the coastal timber trade.

Eureka is a steam powered ferry that served on SF bay.

I was thinking about where to activate and not really looking forward to setting up on or around the public beach. Between the Aquatic Cove swimmers, people enjoying the beach, and tourists going to and fro, there wasn’t really an “out of the way” location to setup even a small station.

Hyde Street Pier itself was actually pretty quiet, but I wasn’t about to set up my station there without prior approval of park staff. Just as we were about disembark from Thayer I noticed an NPS employee near the gangway, and so I took the opportunity to inquire about setting up my low impact, leave no trace, POTA station.

It turns out the person I talked to on the deck of C.A. Thayer was the supervisor of the SF Maritime National Historic Park! He is keenly interested in radio and was even aware of recent solar activities that have given us amateurs a mixed bag of propagation conditions. He agreed to my request to set up at the end of the pier, past Balclutha’s gangway.

Is Balclutha’s steel hull a reflector of radio waves?

I used the Gabil GRA-3750T antenna with its stock telescopic whip tuned for 20 meters. This is the most low profile antenna I can field for HF. Yes, it’s a compromised antenna system but as you’ll see it works good enough. Continue reading Matt’s Low-Profile POTA Activation at the San Francisco Maritime National Historic Park

POTA Field Report: A Morning 40 Meter QRP Activation at Lake James State Park!

On Monday morning (July 31, 2023) I left the QTH with POTA on my mind.

As I mentioned in a previous post, July was a busy month and I was in desperate need of some POTA Therapy! Fortunately, I had the full morning to play radio, so I plotted a two (or possibly three) park rove, starting with Lake James State Park.

Lake James State Park (K-2739)

I arrived at Lake James a little after 9:00 AM and pretty much had the park to myself.

In order to keep my setup time a little on the short side, I chose a picnic table next to my car.

I grabbed my throw line cube and (1st gen) Red Oxx Micro Manager pack in which I’d packed my Discovery TX-500 and accessories.

Since it was in the morning, I planned to spend time on the 40 meter band and, hopefully, work a number of hunters in the surrounding states.

For this activation, I paired my Discovery TX-500 with MW0SAW’s 40 meter end-fed half-wave antenna.

I powered the TX-500 with a homemade 5Ah LiPo battery my friend Joshua (N5FY) sent me a couple months ago.

Of course, since I was using a 40 meter end-fed half-wave antenna, I didn’t need an ATU for 40 meters (or 20, 15, or 10 meters for that matter). Continue reading POTA Field Report: A Morning 40 Meter QRP Activation at Lake James State Park!
