A quick two park KX2/AX1 POTA run starting at South Mountains State Park!

You might have noticed that I’ve been taking the Elecraft AX1 antenna out quite a lot recently. At time of posting, I’ve almost used it for a month’s worth of activations.

In December, I thought it might be fun to only use the AX1 for one 2023 calendar month–say, the month of March–but since I evaluate and review radios and antennas, it’s just not realistic to make that kind of commitment.

That said, I did decide to simply start using the AX1 as my primary field antenna for roughly a 30-ish day period and, so far, that’s working out very nicely. I thought it might give some real-world context and usage for those who still believe I’ve just been lucky the days I use the AX1 in the field. No better way to test that theory than to just do it!

Mini rove!

It’s been a while since I’ve had time to do a proper park rove. I hope to do a five park rove within the next month or so, if I can clear out space in the schedule. I find roves so much fun and a nice change of pace.

On Saturday, January 21, 2023, on the way back to my QTH in the mountains of WNC, I had just enough time to activate two parks in short order. Having just been challenged by a short activation window at the Vance Birthplace (which, turned into a normal length activation due to a schedule change in my favor) I thought it might be fun to once again, show the whole KX2/AX1 set-up and pack-up process in my activation video.

South Mountains State Park (K-2753)

I chose South Mountains State Park as my first stop.

South Mountains has a number of public access points. I decided to drive to the main park entrance and set up at the equestrian picnic area. Choosing the main park entrance added about 15 minutes to my overall driving time; the Clear Creek access would have been quicker, but I’d been there only recently.

New AX1 POTA Activation

by Alan (W2AEW)

I have to admit, I have been bitten “hard” by the POTA bug!  (I blame Thomas!) It started for me in August 2022 while I was on vacation at the Jersey shore.  Since that time, I have completed 48 activations at 19 different parks.  All of these have been QRP, and almost exclusively on CW. This story is about one of my recent activations, which was unique for a couple of reasons.  Read on…

The Park

My job puts me on the road, covering a large portion of the northeastern United States.  When my schedule permits, I’ll hit the road earlier than needed in order to potentially stop for a quick activation along the way (usually giving up a lunch-on-the-road stop in favor of a bit of QRP CW operation at a park).

This particular park was not your typical state park.  It wasn’t a nature preserve, or a mountain lake, or a hiking or picnic paradise.  No, this park is decidedly urban, occupying 2 blocks in the city of Holyoke, MA.  This is K-2439, Holyoke Heritage State Park. According to the state park website, this park celebrates the rich industrial heritage of the city of Holyoke.  The park also includes a Children’s Museum, a Volleyball Hall of Fame and a restored antique Merry-Go-Round.

The park is situated along a canal that once powered some of the mills that were located on the property.

It certainly is not like any other state park that I’ve been to!

One of the reasons I chose to stop at this park is that it had only been activated 4 times in the past.  In retrospect, I suppose this could’ve been because of the city/industrial setting.  Was it going to be noisy? Maybe this was a bad idea.. Thankfully, it wasn’t… Another thing that appealed to me is that it had not been activated on CW before.  So, my activation would be a CW ATNO (All Time New One) for this park, which is kind of cool.

A New Antenna

Largely due to Thomas extolling the virtues of the Elecraft AX1 compact vertical antenna, I “had to” purchase one for myself.  This activation would be its maiden deployment. Continue reading Alan’s window-mounted Elecraft AX1 POTA activation!

POTA Field Report: The Elecraft AX1’s secret power? Speed of deployment.

I believe I mentioned in the past that when I first purchased my Elecraft AX1, I assumed it would be a bit if a toy or novelty item. I thought it was a fun concept–and that’s why I bought it–but I remember the first time I took it out to the field on an activation, I thought I’d be demonstrating that a compromised antenna delivers compromised performance.

In short? I was wrong.

The AX1 has instead become one of the most valuable tools in my antenna arsenal.

When you are the DX–activating a park or summit–the AX1 is more than capable as long as you live in an area with a reasonable amount of hunters/chasers within your normal propagation footprint.

Speed

The AX1’s secret power, as I mention in the title, is speed of deployment.

Although I can launch a line into a tree and deploy an end-fed half-wave pretty quickly–I’ve literally done this hundreds of times–I can deploy the AX1 even more quickly without breaking a sweat.

Case in Point: Zebulon B. Vance Birthplace (K-6856)

On Tuesday, January 17, 2023, I had a day full of errands and projects in town, but needed to pick up my daughters at a school function around 15:00 local. There were too many variables to accurately predict where I would be at what time, so I didn’t schedule an activation that morning.

As the day progressed, though, I realized I had a very short window and K-6856 was practically en route to the pickup point. After I finished my last errand in south Asheville, I made my way north and based on Google Maps, I had no more than a 25 minute window to fit in a full activation from deployment to pack up.

I stopped in a parking lot en route, pulled out my iPhone, and scheduled an activation at K-6856 on POTA.app.

Keep in mind that my activations are typically short, but 25 minutes for set-up, on-the-air time, and pack-up leaves very little margin for error.

The AX1 is perfect for this type of activation.

A little time math

It takes me two easy minutes to set up the AX1 and maybe one minute to pack it up.  If I wanted to, I could speed that up a bit (I take much longer on camera talking my way through the process). So that’s roughly three minutes to both deploy and pack-up the AX1.

My speaker wire antenna, on the other hand, is also very quick to deploy. With my arborist throw line, I can easily prepare that antenna in four minutes and pack it up in three minutes. Thus, I need to allow roughly 7 minutes to both deploy and pack-up the speaker wire antenna (we have to assume it might take 2 launches of the throw line to snag a branch).

Since it has a built-in ATU and battery the Elecraft KX2 takes maybe 20 seconds to set up. Seriously: pull it out of the pack, connect a key, turn it on. Continue reading POTA Field Report: The Elecraft AX1’s secret power? Speed of deployment.

Jonathan takes the Yaesu FT-818ND on an inaugural POTA activation!

Many thanks to Jonathan (KM4CFT) who shares the following guest field report and video:


Chatfield State Park (K-1212)

January 20, 2022

by Jonathan Kayne (KM4CFT)

The honorable Yaesu FT-817/818. You all know it and love it. I had been wanting to get myself one for a while but after just buying myself a shiny new ICOM IC-705, I had been planning on getting myself an 818 in the spring to play around with. December came and I find out that Yaesu was going to discontinue the 818, so I went and bit the bullet and bought one from Ham Radio Outlet.

I had been getting into CW for portable operations lately after wanting to learn CW for a while and my friend Zach Thompson (KM4BLG) had pushed me to learn it. I learned it over the course of two months through an app called “Morse Machine” and listening to Thomas’s YouTube videos while working so as to get used to the exchanges and pick up words. Then I activated and all the rest is history! (If you want to see my 3rd time activating see this video here.)

Why is this important? Because the FT-818ND does not have a narrow 500 Hz filter for CW operation by default, and since I consider myself to be still a newbie I wanted to install a Collins Filter before I take my new 818 into the field. Since these filters are hard to obtain, I went with the build your own route. The method I used has been outlined in this blog and I have made a video of it here.

Now that I had my radio all ready to go with a filter, side rails, and Windcamp Battery, I wanted to get it in the field as soon as possible. Unfortunately due to a snow storm, the temperature in the Denver area was quite cold.

I can handle myself pretty well in the cold if I put on enough layers, but my fingers are another story. I have found that I cannot write properly unless my fingertips are exposed. The solution: do the activation in the car! Continue reading Jonathan takes the Yaesu FT-818ND on an inaugural POTA activation!

Pairing the Elecraft KX2 with a 28.5′ random wire for a rapid POTA activation

On Wednesday, January 11, 2023, I was on my way back to the QTH after a brief trip to Raleigh, NC.

Later in the afternoon, I needed to take my daughters to a class, thus I had a strict deadline to meet. Still, it was a beautiful day so I decided to pop by Tuttle Educational State Forest for a nice walk and possibly an activation if I time allowed.  I’d spent so much time in my car the previous couple of days, I really wanted to stretch my legs.

Tuttle Educational State Forest (K-4861)

As I drove to Tuttle, I made a decision to film a Hike & Talk session–I had a topic on my mind and thought the timing was right to make a recording. You can check out that (previously published) Hike & Talk session here.

After that casual walk, I found that I had a good 45 minute window–no more–to fit in a full activation including set-up/take-down. Very doable!

The radio I had packed away for this road trip was my Elecraft KX2 field kit which included a Tufteln no-transformer random wire antenna (compact equivalent of my 28.5′ speaker wire antenna) and my AX1 portable antenna. I had this particular kit because I’d hoped to do an urban park activation in Raleigh, but simply didn’t have the time to fit it in.

Setting up the KX2 is a swift process.

I chose a picnic table, deployed the Tufteln antenna and was on the air in no time! Continue reading Pairing the Elecraft KX2 with a 28.5′ random wire for a rapid POTA activation

Guest Post: Dan’s first straight key POTA activation

Many thanks to Dan (W9SAU) who shares the following field report:


My first Straight Key POTA Activation

Dan (W9SAU)

1/22/2023

After 3 weeks of working Straight Key for SKCC, SST, and POTA QSOs, and a lot of practice, I wanted to try a Straight Key POTA Activation, using a Cootie paddle.

My Cootie/Sideswiper is a modified Vibroplex Single paddle, with a switch installed. Converting a paddle to a Cootie is done by jumpering the dot and dash wire connections. Then turn the Electronic Keyer off. The switch allows for Cootie or Keyer operation.

Pullman National Monument (K-7917) is only 10 minutes from my QTH. Pullman is unique, with the National Park borders surrounding a portion of the Pullman factory and neighborhood. You can operate from anywhere within these borders. I operated from the parking lot of the Pullman National Monument Exhibit Hall.

In this busy area in the City of Chicago, the noise floor was near S-Zero. There is occasional interference from a passing Illinois Central Electric Train, with QRN that obliterates everything. Not many trains on a Sunday morning.

With snow falling, my operating position was inside the vehicle, using a Yaesu FT-891 set to 5W for QRP, with a Shark 20 meter Hamstick on the roof.

Some anxiety, starting at 13wpm, but I quickly became  comfortable with 15wpm. My goal was to complete the Activation with 13 or 14 contacts.

I finished with 22 in the log in 35 minutes. I appreciate the patience of all who slowed down for me.

I had plenty of protection from Chicago’s Finest!  Across the street are the Pullman Horse Stables. All employee and visitor horses were housed and cared for here, in the late 1800’s.

Working the Cootie is a lot of fun! I find it easier than the traditional up/down key. But each character still has to be formed manually. I will be doing more of this type of POTA Activation.

A bonus is Ops who sometimes initiate a SKCC QSO when I work them for POTA. I was happy to accommodate them, but using a Keyer, I could not take SKCC credit. With the Cootie, I can use the credit to work towards the next SKCC achievement level. All while working Parks On The Air!

New Penntek TR-35 Field Kit, Canine Welcome Party, & Brilliant 20 Meter POTA Conditions!

There are few things that make me happier than radios and pets.  On Saturday, January 7, 2023, I got copious amounts of both.

On the way back to the QTH, I stopped by Table Rock Fish Hatchery (K-8012) for a nice, leisurely POTA activation.

En route to Table Rock I gave some though to the antenna I might deploy. In the end, I decided I’d once again set up the Chelegance MC-750.

There was no question which radio I’d use: it’d be the brilliant Penntek TR-35 packed-up in its new field kit!

Table Rock Fish Hatchery (K-8012)

Table Rock Fish Hatchery isn’t open on Saturdays, but that really isn’t a problem because the picnic area where I set up shop is open 24/7.

And the best part about Table Rock? The welcoming committee…

These two dogs are so incredibly sweet and always a highlight of activating Table Rock. You may have seen them in my previous field reports and videos. Continue reading New Penntek TR-35 Field Kit, Canine Welcome Party, & Brilliant 20 Meter POTA Conditions!

Hike & Talk Session: Conquering the CW Doldrums

A couple years ago, I started making Hike & Talk video sessions covering in-depth topics that are challenging to answer via email or even long-format blog posts.

When I receive a question from a reader and think to myself, “I’d rather answer that in-person than write a reply,” I make a note to do a Hike & Talk session.

These sessions are not scripted, outlined, or formatted in any way shape or form. When I make a Hike and Talk video, I imagine that I’m chatting away with you informally as you join me on a hike or walk.

All this to say that these long-format videos aren’t for everyone, so if it doesn’t sound like your cuppa’ tea, it’s okay to skip it! I promise, I won’t be offended.

Conquering the CW Doldrums

On January 11, 2023, I was driving back from Raleigh and decided that a quick POTA break was in order. That morning, I read an email from a reader and it was on my mind as I drove to Tuttle Educational State Forest. It was a long email, but here are the relevant bits:

Hi Thomas […]I’ve been studying CW on my own for about four months now. I know you advise joining a group like the Long Island CW Club to learn CW but my work schedule simply doesn’t allow for this. I travel frequently and have team members across the globe so my schedule is a mess. I have so little free time.

[…]I’ve been using various CW apps, CW recordings like W1AW and your videos to practice CW. I can’t stress how much your videos have encouraged me along the way because you make this all seem so achievable. I download your videos from Patreon and listen to them when driving, flying, during layovers, and in the evenings in my hotel room. Many times I just listen to your video audio as I would a podcast.

I am not at a point where I can understand all of the contacts you receive, but I do get maybe 1 out of 3. It’s a real thrill to know I decoded a callsign on my own. I see a day when I will do CW activations.

[…]I’m writing though because I feel like I’ve reached a barrier. I know all of my characters and numbers and I continue to do regular CW practice, but I feel like I’m not learning. Like my brain has stopped soaking up the code. It’s discouraging. Do you have any advice for getting through this?

I’ve received similar emails and comments in the past which is proof that you’re not alone if you can relate to this reader.

I’ve certainly been there, too!

Hike & Talk

In this video I will talk about the CW Doldrums, how I related to them, and how I work through them myself.

I include (against my better judgement!) a very long side story about my path to learning French. It relates, but perhaps not how you might think.

Instead of editing my videos, I always try to include chapter markings in the YouTube timeline so you can skip over any sections that aren’t of interest to you.

You’re going to need a few cups of coffee or tea for this one. You’ve been warned!

Thank you

Thank you for joining me on this Hike & Talk session!

If you’re experiencing or have experienced the CW Doldrums yourself, let us know how you work through them in the comments section.

The important part is to know that you’re not alone and that, in fact, the Doldrums are truly a healthy sign that you’re learning CW and your brain is doing it’s thing!

As always, a special thanks to those of you who have been supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free, I really appreciate the support.

Thanks for spending part of your day with me on the trail!

Cheers & 72,

Pairing the Penntek TR-45L and Chelegance MC-750 on a swift POTA activation

Friday, January 6, 2023, was a beautiful day and my route took me within 10 minutes of South Mountains State Park (K-2753).

Of course, I had to activate it!

In truth, I had only a short window to do the activation, but I knew it would be seriously fun.

I’d packed my Penntek TR-45L and Chelegance MC-750 for the trip and was looking forward to pairing the two.

My TR-45L actually has the built-in Z-Match manual antenna tuner, but I wanted to, once again, configure the MC-750 as a resonant antenna (much like I did in my previous activation).

I also had my new VK3IL pressure paddle along for the ride and wanted to see how nicely it might work with the TR-45L.

If I’m being honest, it was a bit strange not to use a wire antenna at this particular park because South Mountains has some very large old-growth trees that are ideal for hanging antennas.

That said, I also had my choice of spots to deploy the MC-750 vertical. Continue reading Pairing the Penntek TR-45L and Chelegance MC-750 on a swift POTA activation

New Year’s Day POTA: New VK3IL Pressure Paddle, New FT-817/818 Narrow Filter, and New TPA-817 Pack Frame!

I try to start each year by doing a POTA or SOTA activation on New Year’s Day.

POTA actually issues a certificate for completing an activation on New Year’s Day so there are typically loads of activators and hunters working the bands. It’s an ideal time to play radio.

This year, we had a number of family activities on New Year’s Day, but I made a little time to fit in an activation during the late afternoon at my most accessible spot on the Blue Ridge Parkway: the Southern Highland Folk Art Center.

As with my last activation, I suspected I would be operating in the dark, so I brought my LED lantern along for the ride.

Although not intentional, this New Year activation had a lot of new-to-me stuff involved!

New VK3IL Pressure Paddle

The prior evening–on New Year’s Eve–while my wife and daughters were watching a classic movie movie marathon, I used the time to heat up the soldering iron and work through a few kits and projects that had been sitting on my desk.

One of those projects was a Pressure Paddle designed by David (VK3IL).

Michael (G0POT) sent me the Pressure Paddle circuit board and heat shrink via Andy (G7UHN) several months prior. [Thank you so much, fellas!]

To my knowledge, the VK3IL Pressure Paddle isn’t available in complete kit package, but it’s quite easy to source everything yourself.

On his website, David provides the Gerber files you’ll need in order to purchase the circuit boards from your favorite manufacturer (I’m a huge fan of OshPark here in the States).

Next, you simply need to order the components. Here’s the list assuming you’re using DigiKey:

  • Quantity of 2: 732-7579-1-ND (CAP CER 10000PF 10V C0G/NP0 0805)
  • Quantity of 2: BSS806NH6327XTSA1CT-ND (MOSFET N-CH 20V 2.3A SOT23-3)
  • Quantity of 2: 311-470KCRCT-ND (RES 470K OHM 1% 1/8W 0805)
  • Quantity of 2: 1738-SEN0294-ND (RP-C18.3-ST THIN FILM PRESSURE S)
  • Quanity of 1: Three conductor wire with a (typically) 3.5mm plug (note that I had one of these in my junk drawer)

Keep in mind: the components are surface-mount. If you’re not used to working with SMD components (ahem…that would be me) I suggest buying a few spares of each in case you lose or damage one or more during the build.

It also helps to cover the finished board in heat shrink not only to protect the board and make it easier to grip, but most importantly (if you’re me) hide your electrically-sound yet unsightly surface mount soldering job.

The build might have taken me 20 minutes.

New FT-817ND Narrow CW Filter

Some time ago, I purchased a second FT-817ND with the idea of doing full-duplex satellite work. I later realized I could be taking the second FT-817ND out to the field more often if I simply had another narrow CW filter installed, so I built one.

This New Year’s Day activation was actually the first time I’d taken this particular FT-817ND and its new narrow filter out to the field!

New Armoloq TPA-817 Pack Frame

Earlier this year, I also decided that I wanted to outfit my 2nd Yaesu FT-817ND with an Armoloq TPA-817 pack frame. The idea was to experiment with building a rapid-deployment field kit around it.

This is actually one of the big projects I’m working on in 2023. I’ve yet to sort out the antenna mount I’d like to use with this frame based on how I plan to deploy it. Continue reading New Year’s Day POTA: New VK3IL Pressure Paddle, New FT-817/818 Narrow Filter, and New TPA-817 Pack Frame!
