The Adventure You Get

10 Comments

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

The Adventure you get is not always the adventure you expect. Recently I’ve been plotting a unique activation of the De Anza National Historic Trail, but that particular POTA activation is going to need a good antenna and just as importantly, time.

This day afforded a few hours in the morning for outdoor radio but not enough to retrace the steps of the De Anza expedition. Instead, I headed down to the San Francisco Bay side for a quick outdoor amateur radio session.

Marina entrance light from years gone by

Since it was was a Saturday, my usual spot at Presidio East Beach was heavily impacted by weekend recreation enthusiasts, so I continued for a quarter mile to the practically empty parking lot east of the St. Francis Yacht Club.

Small dry beach on the marina side of the jetty

Thence on foot past the old stone light tower and the clubhouse of the Golden Gate Yacht Club, you find yourself of the path to the end of the breakwater where a unique art installation sits.

Alcatraz Island at anchor off the point

The Wave Organ is a curious sculpture that uses tubes and cavities between old cemetery stones to channel and amplify the watery sounds of waves as the tides move in and out of the Bay.

Surrounded by saltwater at the end of this jetty, which by my reckoning is within the boundary of the Golden Gate National Recreation Area (US-0647), this location was perfect for the “no impact” operation afforded by the Elecraft KH1.

This granite wall served as the operating bench

My plan was to see if I could complete an activation of making 10 contacts entirely by hunting other POTA activators, perfectly reasonable given it was a weekend with no geomagnetic storms to disrupt radio propagation.

An entire station in the palm of your hand

What I did not count on was that it was a contest weekend with both 20 and 15 meters wall-to-wall with rapid fire contesters. As a QRP station, finding the POTA needles in that haystack was going to be tough.

The wave organ is a naturally contemplative environment

I retreated to 17 meters which should offer good daytime propagation and no contesters. There on 18 MHz, I was was able to collect five park-to-park contacts in a span of 23 minutes.

At that point I’d exhausted all of the 17m active CW stations on the POTA spots page and didn’t really have time to wait for more to show up. Therefore the “all hunting” activation strategy was abandoned and I commenced calling “CQ POTA.”

A fresh charge delivers nearly 6 watts into a matched antenna on 17m

The activation was “validated” with a call from Dave, AA7EE as the 10th QSO and then completed with one more park hunted, K9DXA in US-1001. Most of the contacts were with stations east of the Rockies.

One thing I learned from earlier outings with the KH1 was to not cut the log sheets too small, as might be suggested by the lines printed on the page. Without enough paper under the top and bottom tabs of the logging tray the sheets can easily be caught and snatched away by the wind.

Leave enough margin on the logging sheets and they are easily secured in the tray, even in the face of brisk Bay breezes.

Looking across the marina entrance toward Fort Mason

The “hunting only” activation plan didn’t quite work out but it was a great time out playing radio at scenic spot in San Francisco Bay.

Sailing season is well underway on SF Bay

While I didn’t expect to activate from the wave organ today, it turned out to be a fun adventure and an excellent spot from which to get on the air with the KH1.

Soggy POTA: Pairing the Elecraft KX2 and AX1 Amidst Flaky Propagation!

6 Comments

On Saturday, May 4, 2024, I drove to the Hickory, NC area to visit my father, who had recently been released from the hospital and was starting rehab at a skilled nursing facility. I had a busy afternoon planned back home in the mountains, but I couldn’t resist squeezing in a quick POTA activation!

Many of you know this is a recurring theme for me – it’s rare that I have a lot of time for activations. I’d be doing far fewer if I couldn’t manage 45-60 minute windows to set up, operate, and pack up.

Tuttle Educational State Forest (K-4861)

The facility where my father is staying is only about 20-25 minutes from Tuttle Educational State Forest, so I had to stop by.

It was rainy that Saturday, so I was already thinking about Tuttle’s excellent picnic shelter. I had my Elecraft KX2 and AX1 antenna packed, and while operating under a metal roof with a compromised antenna isn’t ideal, I’ve had surprising success in the past, including one of my first Transatlantic Park-to-Park contacts (click here to read that field report).

I arrived at Tuttle and found that there was no one in the parking lot. Not surprising considering the weather.

I grabbed my gear and headed to the shelter, only to discover that the lights were on and it was reserved from noon to 5:30 PM. Dang!

Even though it was still drizzling, I wasn’t too concerned. Tuttle has plenty of trees, so I figured I could find a spot under a good canopy to protect my gear. I went back to the car for my rain jacket and my new folding foam seat.

A Funny Story…

I had been planning to buy the Nemo Chipper Foam Seat from REI, but a couple of days after adding it to my cart, one arrived in the mail!

It was a gift from Al (N4EII), who mentioned he loves his and uses it for SOTA and POTA because it’s so lightweight and portable. I think it was this very rainy activation that prompted him to send me the Nemo seat!

Thank you, Al, for reading my mind! So very kind of you!

Setting up

I found a picnic table under a heavy canopy and set up my Elecraft KX2 and AX1 antenna–one of my favorite radio/antenna combos.

That said, I was definitely taking a bit of a gamble. Band conditions (a recurring theme here lately) were quite rough and using a compromised antenna would be risky compared with, say, a much higher-gain 40 meter end-fed half-wave. But the AX1 is so quick to deploy, which is key when time is limited.

Gear:

On The Air

It being midday, I decided that 20 meters would likely be the best band choice.

I started calling CQ POTA and was a bit surprised that my first contact was Michael (N7CCD) in Washington State.

Michael is in my logs a lot–even though he runs QRP from home most of the time, he has a very effective hex beam that casts a signal into NC with ease. With the bands in such rough shape I didn’t expect to work him that day.

Then again, many of the solar numbers have been healthy, it’s just that the ionosphere has been quite unstable. This usually results in deep QSB (fading) thus contacts may be strong one minute, then completely gone the next. This is how I felt conditions were at Tuttle that day.

I continued logging stations at a very respectable rate. I did note a lot of activity from 5 land (Texas and Mississippi). It’s funny how sometimes a path will open like this. Indeed, Texas has had a most welcome opening into North Carolina a lot lately.

In the end, I worked a total of eleven stations–one more than the required ten for a valid POTA activation.

I did all this in just 16 minutes on air. That’s actually an impressive rate considering propagation was so flaky.

No doubt, I could have worked more stations if I had the time.

QSO Map

Here’s what this five-watt activation looked like when plotted out on a QSO Map (it’s still hard for me to believe this can be accomplished with such a small antenna!):

Screenshot

Activation Video

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

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

Soggy POTA

Rainy weather doesn’t stop me from activating if I have my mind set on it.

That said, when it’s raining, I do seek out parks with shelters. It makes the whole set-up process easier and quicker.

Ideally, you want your antenna out in the open, but I’ve even used quarter wave verticals in shelters without issue (I’m thinking of this Lake Norman activation in particular).

Of course, I also keep a small rainfly in my car for makeshift shelter if needed. With a rainfly, camping chair, and kneeboard, I can activate in the wettest of weather. In fact, a rainfly saved this quick Field Day activation last year.

And of course, when raining, you can always activate from inside your vehicle! That may be the easiest option of all for some of us.

Again, Al, thanks again for the Nemo seat – it’s fantastic!

Thank you

Thank you for joining me during this activation!

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

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

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

Thanks for spending part of your day with me! And today being Memorial Day, my thoughts are with families who’ve lost loved ones in service to their country.

Cheers & 72,
Thomas (K4SWL)

A Pretty Picnic for the POTA Babe

Those of you who follow my articles know I generally activate in the morning. However, as school just let out for my son, we’ve transitioned to a summer schedule and that means horseback riding lessons are now in the morning. With my afternoons uncommitted, I’d like to give hunters who may miss me in the morning an opportunity to hunt me  by activating later in the day.

Wednesday, May 22nd, I resumed my 60 new-to-me park activation goal as well as the pursuit of the WMAs near the Altamaha River by heading to Clayhole Swamp WMA (US-3740). Clayhole Swamp WMA is a 8,500 plus acre property along the south side of the Atlamaha River.

I arrived at the property around 3 PM and began looking for an activation site. I first thought to activate near the river as Glenn W4YES and I did at Sansavilla. However, I didn’t have time to drive all over the park as I wanted to be on the air at 4 PM. An hour sounds like gracious plenty of time but when you are driving up and down dirt roads in an unfamiliar area, it isn’t.

The road into the property (as you saw in a photo above) is well-packed and maintained. However, as you drive further into the WMA, other roads are less so. I found Lemmond Road and gave it a go. Given the recent rain, it was a bit on the boggy (but no less fun) side.

Eventually, it became two ruts in the forest and I appeared no closer to finding the river. Also, a multitude of flies swarmed all around the car. At this point, despite having fun mud-bogging on the road in my Subaru Crosstrek “Kai,” it was time to turn around and find a less buggy and muddy QTH.

I retraced my path to the entrance and a little past the entrance into the WMA found a clearing off to the right. The terrain was such I could drive the car just a little way in and set up my station.

There were trees all along the side of the clearing. I donned my blaze orange vest and hat and pulled out my arbor line and weight. Amazingly, it took just one toss to get a line up and in no time, my EFRW was hoisted and ready. I oriented it southeast hoping to get good coverage to the west but also the northeast which turned out to be the case.

The site I chose was shady so despite the afternoon temperature being in the 80s, Daisy and I were cool. I also brought along her cooling vest from Ruffwear. You wet the vest and put it on the dog. The evaporative cooling it provides can lower the temperature for the dog by 3-4 degrees. It worked. She didn’t pant at all during the activation while wearing the vest. This piece of equipment will come in handy for POTA in the summer.

I began with 30 meters, logging 4 contacts before moving to 20 meters. Twenty meters gave me 11 contacts, including a park-to-park (P2P) QSO with John W4ER at US-3691 in Alabama. Continue reading A Pretty Picnic for the POTA Babe →

POTA Activations in Canavese: Monti Pelati and Laghi di Meugliano

1 Comment

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

POTA Activations in Canavese: Monti Pelati and Laghi di Meugliano

by Christian (IX1CKN)

My Canavese connections, tied to the fact that my mom is from San Giorgio Canavese, have been strong since I was a child. Yet, at the ripe age of 50, I realized there are corners of that Piedmont area I hadn’t explored.

I discovered two such places this afternoon, activating POTA with Andrea (IW0HK), a significant motivator for seeking out new references. The first was the Monti Pelati and Torre Cives Natura 2000 (IT-0178), in the municipality of Vidracco (though the protected area also includes parts of Baldissero Canavese and Castellamonte).

This interesting site, reachable within 20 km of Ivrea, is where IW0HK and I met, coming from opposite directions. A short walk from the parking area leads to the summit, where Torre Cives stands, with a panoramic viewpoint facing east along the way.

Upon reaching the parking area with informative signs about the reserve.

Overall, not too many trees, altitude (around 570 meters), and a 360-degree view, an optimal situation for HF (High Frequency) operations.

At the “peak,” we set up the HF station with Elecraft KX3 (8 watts), using a quarter-wave vertical on the ground (also on 40 meters, with the appropriate coil), and followed 144 MHz with Quansheng UV-K5.

No need to dwell on the propagation conditions this weekend (with Aurora seen in southern Florida, and around Rome in Italy!). In shortwave, given the sun’s antics, the situation wasn’t promising at all.

However, Andrea and I decided to overcome this fear. Hamradio is, above all, about experimentation and activity. So, instead of worrying about how many would respond before leaving home, we decided to go, turn on, call, and tally them up.

In 34 minutes on-site, we logged 16 QSOs. Nine on 20 meters, 4 on 40 meters (the coil seems to be working, although you can’t expect miracles compensating for a significant lack of physical length in the element): 1 on 15 meters, and 2 on FM 144 MHz.

As you can see from the map, the responders were mainly POTA friends: Spanish, Polish, and English stations. I won’t list the calls, but you could guess them. However, local stations also responded, even on HF, which is always pleasing. With some, it was natural to try 2 meters as well, getting solid signals.

So, satisfaction despite the complicated propagation, whether for the validity of the activation or for discovering a new place.

Ritual photos with the tower, and off to the second reference.

We’re talking about IT-1634, Laghi di Meugliano and Alice. We’re still within a twenty-kilometer radius of Ivrea (in the Turin province). This time, the municipality is Valchiusa (in Valchiusella), and the lake basin sits at 720 meters above sea level. Now, don’t let the fact that we’re about 200 meters higher than the previous reserve fool you. For HF operations, we immediately encountered a less favorable situation because the lake is of morainic origin, nestled in a sort of basin with trees all around.

We chose not to set up right at its edge (it was quite crowded being a Sunday), but – also fearing the rain (which was forecasted) – in a pine-like area near the restaurant that serves the lake.

The quarter-wave antenna, planted on the ground, perhaps wasn’t in the most unobstructed condition possible, but at least we could take advantage of the shelter of the trees and a convenient table/bench.

Here, besides the propagation conditions, maybe the timing didn’t help much either, as we started the activation at 15:30 UTC. Probably, it’s a time when anyone, in half of Europe, on a Sunday afternoon that’s easy to imagine being warm in a good part of the continent, isn’t at home. Anyway, we replicated the pattern of the previous activation, starting on 20 meters with the calls…

In this case, the activation lasted for 32 minutes. The overall result is 15 contacts. Ten ended up logged on 20 meters (including the always active I1JQJ Mauro), two on 40, and three on VHF 144 MHz. Regarding this last band, I would like to highlight both the QSO with Daniele IU1LCI, for a total of 47 km from his QTH, and the one with Beppe I1WKN and Fabrizio IZ1DNQ, who were mobile returning from a SOTA in Valle d’Aosta (ironically, I had contacted them before descending into Piedmont) and stopped near Ivrea to try the contact.

Once again, both Andrea and I, as we returned to the car to head home (and witnessed, among other scenes that only POTA can provide to a hamradio enthusiast, the movement of a flock of sheep), were filled with happiness at the sight of a new place.

Above all, though, as we reviewed the log, the activation remains an opportunity where some ham spirit close to the roots prevails, which warms the heart to keep seeing. Wanting to exaggerate, on the way back to the Ivrea toll booth, there was still the Bellavista hill with its woods and marshes (which is reference IT-1635), but time had truly run out, so that’s for next one.

A Glancing Blow for the POTA Babe

by (Wednesday, May 15th, Glenn W4YES and I decided to activate a new park for me – Sansavilla Wildlife Management Area (US-3773), a wildlife management area (WMA) along the Altamaha River next door to my last activation – Penholoway Swamp WMA.

Google maps

We arrived at a decent hour (9 AM) and ahead of schedule. The entrance is off Highway 25 and across the railroad tracks. After passing a church, the road changes from pavement to dirt and the fun begins!

We drove down what is Sansavilla Road almost until it dead-ends as I hoped to set up close to the Altamaha River. However, along this road ran a good set of power lines. Given I would run QRP, it was time for Plan B.

We backtracked, took a right onto River Road and then a right toward the river. This road dead-ends at a public boat landing inside the WMA. There is a pavilion with concrete benches and tables. A short distance beyond the pavilion is the landing to which we drove for a quick view of the river whose current moved at a rapid pace.

Glenn joined me this activation and, given the last experience, we made some changes to his set-up. Instead of using my Yaesu FT-891, he brought the Yaesu FT-991A in his possession with which he familiarized himself over the past week. He dialed the power down from 75 to 5 watts. (Yes, he’d be working QRP!) He also switched antennas from the Pacific Antenna 2040 trap dipole to the Chelegance MC-750, hoping the set up would be easier and give him the flexibility of changing bands.

KK4Z: Achieving Another Kilo Despite Solar Interference

Many thanks to Scott (KK4Z) who shares the following post from his blog KK4Z.com:

By the Hand of God at US-2173

by Scott (KK4Z)

I book my campsites often months in advance to ensure I get a good campsite. This particular trip was postponed twice due to typical life events that take precedence over having a little fun. Even this trip was not without its own issues. My wife and I forgot that this weekend was also Mother’s Day and unknown to us at the time of the booking was that there was going to be a 4 major Coronal Mass Ejections (CME) making an earth strike during the trip.

The last time I witnessed solar storms of this magnatude, I was in Gulfport MS doing EmComm for my Church in the aftermath of Hurricane Katrina. It was a humbling experience and it shaped my EmComm Philosophy.

I use the same gear for EmComm and FunComm. The equipment gets tested and exercised, and I remain proficient in its use. I also have an understanding of its strengths and weaknesses.

Most trips I take my go box.

It stays packed and contains everthing except a battery or generator to operate. I do keep a small switching power supply for mains power when it is available. Here is a look at the inside.

I have built rack mount or shelf type go boxes and in general, I do not like them. I have deployed to real disasters and found what I have here works the best for me. I do this enough that I am up and running in minutes. One thing I like is the versatility of being able to adapt my radio to the space I have to set up in. Your Milage May Vary, but for me and my 26 years in EmComm; this works best for me.

This weekend was spent at F.D. Roosevelt State Park (US-2173) near Warm Springs GA. The park was named after Franklin Delano Roosevelt. He suffered from Polio and often would travel to Warm Springs GA for hydrotherapy. He built a residence there often referred to as “The Little White Hose”. During his presidency, he established the Civilian Conservation Core (CCC) during the Great Depression. This provided jobs to young single men to help families who had difficulty finding jobs. The CCC built much of the park.

The park contains 9,049 acres (largest in GA) and is built along the Pine Mountain Ridge. It is the southern most moutain range east of the Mississippi River. The highest point is Dowdell’s Knob at 1,395 ft and is a popular POTA and SOTA (W4G/CE-004) site. I took the Radio Flyer and stayed at the campgrounds near Lake Delano.

I arrived there right at 1300 hrs eastern (check-in time) and quickly got myself settled and ready to go. I knew the solar storms were coming and that my time maybe short. I wanted to finish my kilo here (#6) and needed 310 QSO’s. I had already postponed this trip twice so I was a little edgy. My gear for the trip was my 28.5′ Random Wire Antenna with the Peter my IC-7300. I had my Lenovo Thinkpad T-14 laptop and used mains power. The nice part about the antenna besides it performance, is I get zero complaints from park employees. No wires in the trees nor holes in the ground.

Friday’s band conditions were okay. There was lots pof QSB and I stuck with FT8 (35 watts). CW in these more rural parks can be iffy and this go I needed quantity. I started at 1430 hrs eastern and by oooo hrs Saturday (Friday Night) I had 134 QSO’s and when I quit at 2315 hrs I had a total of 230.

Saturday morning, after a quick breakfast I started up again at 0730 hrs. I operated until 1140 hrs when the bottom dropped. Luckily, I ended up with 338 QSO’s including 3 that were mader after the CME hit.

I decided my time would be best spent at home to spend Mother’s Day with my Lovely Bride so I packed up and headed for the house. My stats refelected band conditions and even though I made quite a few contacts, I only had three DX entities: Alaska, Canada and Mexico. I made contacts in 40 of the 50 states.

Operating this weekend reminded me that as reliable as HF commnications can be, it does have its Achilles Heel. For those in EmComm, never stop practicing, refining your techniques, or keeping your gear in order. For everyone else, it’s just another day in paradise.

K4AAC & K4RLC: SOTA Babe in the Clouds at Mt. Jefferson

4 Comments

Many thanks to Bob (K4RLC) for the following field report:

SOTA Babe in the Clouds at Mt. Jeff

de Bob (K4RLC)

Two weekends ago, Alanna K4AAC & I took a short trip to the beautiful Blue Ridge mountains of North Carolina to combine a POTA Weekend and Summits-on-the-Air. We stayed at the New River State Park, a small newer state park that the New River (actually the oldest river in North America) transverses. New River SP is also near some SOTA peaks and the idyllic Blue Ridge Parkway, an almost 500 mile highway that follows the Blue Ridge mountains, starting near Cherokee, North Carolina and ending in Northern Virginia.

Courtesy: National Park Service

This was a needed trip to the fresh air and incredible vistas, as this year brought health problems for both of us, especially an Emergency Room visit for Alanna Easter weekend. Fortunately, with great physicians from UNC and med changes, she was able to rebound fairly quickly.

Friday, we set up a trap Inverted-V on a push-up pole, lashed to the campsite split rail fence. For the radio part, the goal was to put the new Elecraft KH1 through it’s paces. While most rave about this new hand-held CW rig, I still prefer my KX2. Anyway, Friday night with 3 watts on 40 CW with the KH1 and the inverted-V. As it was rainy, I ran the coax inside our Winnebago Solis and set up at the kitchen table (the Winnebago Solis is their smallest vehicle, really just an ergonomic camper van built on a Dodge RAM Promaster chassis).

With a 140 watt solar panel on top and two 100-ampHr batteries, you can boon dock off the grid for several days. Had a productive run of Qs sitting at the table, and with several other LICW members.

As the weather report for Sunday was bad, we decided to do a Summits-on-the-Air activation Saturday on near-by Mount Jefferson, a nearly 5000 ft peak named  for its original owners, Thomas Jefferson and his Father. This is a partial drive-up south of the town of West Jefferson (named for ?).

There are several trails on the top, including the Mountain Ridge Trail and the Lost Province Trail. The trails are incredibly well maintained, flat gravel trails, not like the rock scrabble of the AT, but a definite steep incline. Alanna did great climbing  the steep trail, only having to stop a few times to catch her breath.

About half way up, we were in thick clouds, with visibility only a few feet. It was ethereal. At the SOTA activation zone, there is a rock ledge where you can set up….but be careful, as you don’t want to tumble off the ledge, way down to the valley below. At first, Alanna operated in the clouds. She looked like a spirit SOTA babe emerging through the clouds.

Mt Jeff overlook in the clouds

A few hours later, a cold front came through and blew the clouds away. What a difference! We could see 70 or more miles, down the valley and into the nearby state of Tennessee.

Mt Jeff overlook in the clear

Unfortunately, there was a major solar flare, with an A Index of 12, so conditions were very rough. At first, I tried the KH1 as a hand-held with the attached 4 foot whip and one 13 ft counterpoise. To make conditions better, I set up the Elecraft AX1 miniature vertical on a tiny tripod and attached four 13 ft radials, in the trees and over the rock ledge. It was still an effort, but managed to get the required SOTA contacts. As Mt Jeff (W4C/EM-021) is both a SOTA peak and a NC Park natural area, it’s a two-fer. Unfortunately, my luck capped below the required number of POTA contacts. Thanks to all who tried to dig me out. The Reverse Beacon Network spotted  us around the country, but with very weak signals on 20 CW.

Sunday, the weather was hit and miss, so we decided just to drive the Blue Ridge Parkway (US-3378), stopping at breath taking overlooks and hiking some on the Mountains-to-the-Sea trail. The MST runs almost 1200 miles from the Great Smoky mountains in the western part of NC to Jockey’s Ridge State Park in the Outer Banks, where North Carolina meets  the Atlantic Ocean. We’ve section-hiked the MST, just as we’ve done on the Appalachian Trail.

Cooking  over an open campfire is the only way to get that great wood smoke flavor. Our hot dogs and hamburgers by campfire, with guacamole, were delicious.

Looking forward to trying the KH1 in decent propagation conditions, as it may be the go-to for SOTA and overseas travel.

All-in-all, the clear clean mountain air and great mountain vistas were really therapeutic for our health, and the kind of medicine you can’t put in a bottle.

The POTA Babe Gets a Partner!

13 Comments

Those of you that read the final article for my spring-break Florida POTA trip know that I recently reconciled with someone dear to me. This man, Glenn W4YES, has moved to Savannah, Georgia and we are in a relationship. He is a CW op and the person behind CW Innovations’ Comprehensive ICR course. He knows how much I love POTA and joined me Friday, May 3rd for an activation.

I could have resumed my quest for 60 new-to-me parks. However, I figured we had enough “new” stuff going on with a new activator and a different set up for Glenn. POTA tends to throw the unexpected at you already and the more variables you add, the more opportunities there are for mistakes (er, learning opportunities) and/or hilarity to ensue. So I chose to return to Evans County Fishing Lake (US-7464), a site already known to me, for our dual activation.

What a gorgeous day! Sunny skies and 71 degrees! The drive is a short (about 50 minutes) and easy one to this park.

Given Glenn would use QRO equipment and didn’t have a chair or knee board like myself, I chose one of the few spots with a picnic table. The site looks out on Bidd Sands lake. We could have shared my QRP set-up but decided to activate at the same time which necessitated two sets of equipment.

boaters on the lake

I chose familiarity over reinventing the wheel when it came to picking equipment for Glenn – I grabbed my Yaesu FC-50 tuner and Yaesu FT-891 rig from my ham shack and the Pacific Antenna 2040 trap dipole antenna and SOTABeams travel mast from my equipment stash. This was the set-up I used for POTA before I went QRP with the KX2 and Tufteln EFRW last May. It wasn’t long before a station was set up on the picnic table for Glenn. However, the antenna was another matter.

Glenn’s set up

When I grabbed coax for the antenna, I forgot the connector is a BNC connector which is why I have a coil of RG-174 in my stash. Instead of grabbing that RG-174, I grabbed my 50’ coil of RG-8x. (Doh!) That coax is extremely heavy for the SOTABeams travel mast and, after adding an adapter for the BNC to SO-239 connector, the antenna was hanging over precipitously. It just goes to show how well-made and durable the SOTABeams travel mast is. I was mortified as I like the best possible arrangement for my antennas but Glenn wasn’t. He knew what we had was good enough for contacts (see his QSO map down below) and his thinking turned out to be correct.

While Glenn finished getting everything in order for his activation, I began setting up for mine. I know this park allows antennas in the trees so it wasn’t long before the trusty Tufteln EFRW was installed. Daisy and I chose a shady location near the antenna, got comfortable, and began my activation.

As Glenn was running QRO (the power I usually run on my Yaesu FT-891 is 75 watts) on 20 meters, I began working other bands. I initially wondered if I would have any difficulty running a QRP station so close to a QRO set-up, but I didn’t. Continue reading The POTA Babe Gets a Partner! →

A CW Operator’s First Look at the (tr)uSDX by Malahit

by Bob Houf  (K7ZB)  

April 22, 2024 – Gilbert, AZ

I recently bought an assembled (tr)uSDX from Amazon.com [affiliate link] in April, 2024, the mainboard is version 1.2 and the RF board is version 1.0.

Due to antenna limitations – a 17-foot wire antenna with a 6-foot counterpoise hanging from a second-floor condo balcony, matched through a Tokyo Hi-Power antenna coupler for an SWR well below 2:1 – I’ve been operating exclusively on the 20-meter band.

A short coax run into the dining room has given me some great on-air time over the weekend, with good band conditions for 20-meter CW.

The radio powers up when 13VDC is applied and I quickly figured out the menu structure with the minimal documentation available from DL2MAN.

I’ve learned that the filter is best set to 500Hz and it is effective for the conditions, and as the band gets hot with all the various weekend contests, I drop in a little attenuation and soon the radio begins to sound good – actually, for the money, it sounds really good.

QSK set to ON allows my keyer in Iambic B to do a good job and I don’t miss any contacts which are forthcoming across the US from Oregon out to the East coast, on down to the Virgin Islands and then, quite a surprise, my Magnificent 7 Watts is heard for a choice contact with a VK2 down under.

I pound out contest QSO’s all up and down the band, adding in a few SOTA and POTA stations and very few have trouble copying me – I certainly had no problem copying weak signals from them.

I do notice that this is not a $1,500 transceiver, especially in the receiver performance, but for the price the satisfaction derived from effortlessly working CW makes up for any limitations.

During the MST contest, as I write this, stations were piled on top of each other. I found that tightening the filter down to 50Hz wasn’t ideal – 500Hz worked better for my ears. Signals filled the band from 14.030 to nearly 14.050, ranging from very weak to extremely strong. Thankfully, the well-behaved AGC prevented any ear-splitting surprises.

I also tested SSB mode briefly and it works and sounds good, though I’m unlikely to use it much myself.

Overall, this little gem is far from a toy. With its filters, AGC, attenuator, and fine-tuning, it should bring a smile to any CW operator’s face.

KK4Z: The Happenstance Rove

Many thanks to Scott (KK4Z) who shares the following post from his blog KK4Z.com:

The Happenstance Rove

by Scott KK4Z

Happenstance: a chance circumstance.

That is how it started out.

I recently sold one of my radios and, for giggles, I thought I would check out QTH.com to see if there was anything I just had to have (Danger Will Robinson). I stumbled across a nice IC-7100 and thought I could install it in my truck to make quick POTA activations a little easier. The ad looked good and the call sign sounded familiar. I checked the seller out on QRZ.com. I do this with every ham radio transaction to reduce the opprtunity of being scammed.

Low and behold! the seller John KX6F, is an old army buddy of mine. We served together in the 101st Airborne Division in C/158 TF 160. That was 40 years ago and I hadn’t seen him in at least 15 years. John is a good guy and was a major influence to me becoming a ham. I served with him from about 1980-1983 when I was transferred to Germany. Life and stuff took over and I was finally able to get licensed in 1995.

I sent John an email asking if I could pick up the radio in person and take him out to lunch. He told me that he suffered a severe stroke a couple of years ago and that dining in would be a better option. No problem. On Monday 04/22, I asked when would be a good time to come. He said Tuesday would be good. I had one night to plan a trip. He lives about 5 hours away from me so I thought I would turn this into a rove. I decided on two nights of camping and 5 parks in 5 states. The XYL had a hip replaced so I hadn’t been out in a while, it was time to stretch my legs.

Here is a map showing the stops.

Blue is day one, red is day 2 and green is day 3 and the trip home.

#1 Clarskville, TN. First stop was John’s. We had pizza for lunch and reminisced about old times. John looked good and was as jovial as ever. I was glad I made the trip. He and his wife were very gracious. After about an hour and half, I could tell it was time to go. The radio is in great shape and I am sure I will enjoy it.

From John’s house I drove to Lake Barkley State Park (US-1284 and #2 on the map). I spent the night there in a very nice campsite. Right at dusk, a Barred Owl flew into my campsite. He was less than 20 feet away from me at eye level. Once we made eye contact, he flew off to another perch – silent as a ghost.

All the states on this trip were new activation states for me so I made sure I had enough contacts for a valid activation. I was prepared to do either CW or FT8 but due to band conditions, it looked like FT8 was going to be the weapon of choice. I made 20 contacts and managed to work Australia, Canada and France.

Wednesday morning I broke camp and headed toward Ft Massac State Park (US-0993 and #3 on the map) just over the line from Kentucky. It was a nice park inside of the town of Metropolis. I found a spot with clean restrooms nearby and enough room for my truck and camper. There were a lot people using the park to exercise. I used FT8 to make 20 contacts on 30 and 10 meters and the only DX was Canada.

From Ft Massac State Park my next destination was Big Oak Tree State Park (US-1749 and #4 on the map) in MO about 1 1/2 hours away. Along the way near the town of Omstead, IL, I spotted a Bald Eagle having lunch with Vultures at the roadkill cafe.

The park is located in rural MO. and surrounded by farms. There was no cell service here but the park and the views were great. I set up near the picnic area. Ten meters was hopping. DX stations included: Hawaii, Belize, Portugal, Puerto Rico, Sardinia, and Spain. I was running 25 watts. I made 20 contacts before packing it up and moving to my next park.

Stop #5 and my second overnight was Mississippi River State Park (US-1102). This was a very nice park and I managed to reserve a campsite on the water. It also had zero cell service, even my cell phone went SOS.

My money band was 10 meters again making DX contacts with Argentina, Australia, Brazil, Canada, Chile, Japan, and New Zealand. Ten meters acted like 20 meters, and 20 meters acted like 40 meters. I ended up with 33 contacts total.

Thursday morning had me heading toward home with Georgia on my mind (I even heard the song on the radio). I made a stop at Trace State Park (US-2554 and stop #6) just outside of Tupelo, MS. I stayed long enough to make 20 contacts and one DX into Canada.

I got home about 1600 hrs eastern Thursday afternoon. I worked 5 parks in 5 states: Kentucky, Illinois, Missouri, Arkansas, and Mississippi, in 2 days. I crossed 4 major rivers: Cumberland, Tennessee, Ohio, and Mississippi (twice). I added 5 new states to my POTA activations.

It was a good trip considering I only had about 2 hours to plan it. I learned some new things about my equipment and I have plans to make things better for next time.

My first rove proved to be a lot of fun. Usually I drive to a park, spend a couple of days and then drive home. I am hoping to try another rove before the year is out.
