Postcard Field Report: Pairing the Elecraft KX2 and Packtenna 9:1 Random Wire at Holmes Educational State Forest

6 Comments

Well, I’m off to Hamvention in two days and trying to prepare for the trip. There’s so much to do!

If you are attending Hamvention this year, I’d love to meet you. Stop by the Ham Radio Workbench/Halibut Electronics table (#3011) and introduce yourself.

Since my travels this week are imposing on my field report time, I’m going to share another, shorter, Postcard Field Report. I hope you enjoy it:

Holmes Educational State Forest (K-4856)

On Friday, April 21, 2023, I had a short window of time to fit in an activation while my daughter was attending her high school robotics class.

Her robotics class lasts nearly two hours, but it’s 30 minutes away from all parks and summits, so traveling to/from a site takes about one hour.

I didn’t care because I had a particular park in mind: Holmes Educational State Forest (K-4856).

It had been one year almost to the day since I last activated Holmes.

I arrived on site around 13:30 local, and there were only a few other people floating about.

I walked up the main loop path in search of a good picnic table that was out of the way and with ample trees about.

In a pinch, any of the picnic table sites would have sufficed, but since I practically had the whole park to myself, I could afford to be picky!

The sign above reminds me that Educational State Forests in North Carolina have hours that vary by season and truly cater to school groups, thus are primarily open during the school day. Always check those hours before embarking on a journey to this type of park.

One great thing about our Educational State Forests is that they almost always have a nice covered picnic shelter for school groups. If they’re not occupied, they’re perfect for POTA activators who’d like to escape heavy rains. You can see the one at Holmes off in the distance in this photo:

I ended up choosing the same picnic table I used last time–it had more room around it to set up an antenna without crossing the path.

I didn’t have a lot of time to set up and operate, so I chose to use one of my speedier deployment combos: the Elecraft KX2 and PackTenna 9:1 Random Wire. Continue reading Postcard Field Report: Pairing the Elecraft KX2 and Packtenna 9:1 Random Wire at Holmes Educational State Forest →

QRP DX: A beautiful day for SOTA on Flat Top Mountain!

23 Comments

The weather on the morning of April 4, 2023, was absolutely outstanding!

I woke up that morning, drank a cup of coffee, looked outside and knew what would be in store the day: a SOTA activation!

My schedule was actually open that fine Tuesday because my daughters were on spring break from school, so the only problem was deciding which summit to activate. A good problem, in other words!

After staring at the SOTL.AS map for a while, I decided to activate Flat Top Mountain (W4C/EM-026) near Blowing Rock, North Carolina. One of the main reasons I chose Flat Top was because the roughly five mile round-trip hike is such a pleasant, casual one. My left ankle was recuperating from a bit of a strain, so I knew Flat Top’s flat, wide carriage trails would fulfill my need for exercise without straining my ankle (which, by the way, is doing much better now).

The drive to Flat Top is a beautiful one–a good third of it is on the Blue Ridge Parkway including the Linn Cove Viaduct which offers up stunning long-range views. I made my way to Moses H. Cone Memorial Park, at BRP milepost 294, where I parked the car and put on my hiking boots.

The park was pretty active for early April, no doubt because the weather was so stunning.

I checked out the beautiful Flat Top Manor to see if renovations had been completed.

It looks very close to completion, I have to assume they’ll be open again soon. The old manor was looking beautiful against clear skies!

Flat Top Manor was built by in 1901 by Moses Cone who was a very successful local textile entrepreneur, conservationist and philanthropist. It’s so fitting that this beautiful bit of architecture and these expansive grounds (which includes no less than two SOTA summits) are now protected by the National Park Service for all to enjoy.

I started my hike by following one of the carriage trails in front of the manor. It leads past a farm building, then crosses under the Blue Ridge Parkway two-lane road. Continue reading QRP DX: A beautiful day for SOTA on Flat Top Mountain! →

KN4OK’s Mini POTA Field Report from the Florida Keys

Many thanks to Dave (KN4OK) who shares the following mini POTA field report:

POTA Activation K-3620 Florida Keys Overseas Heritage Trail State Park.

By Dave (KN4OK)

On April 8th, 2023, on our way to the Overseas trail near the 7 mile bridge, is a great place to activate with a picnic table and shade on the water.

I was smart enough to mention to the wife that we were going to activate a park and she was carrying my Elecraft KX2.  Of course, in my hand was the antenna, the MFJ-1889T, and counterpoise wires that I borrowed from my WRC antenna.

After a mile hike on the trail, we stopped at the picnic table and I set the station up on 17 meters CW.  The SWR was pretty good and I made 9 contacts with no problem.  I then switched the radio and antenna to 20 meters and obtained a better SWR.

One thing that I noticed: extending the counter poise wire (33ft) all the way out for both bands helped a great deal.  The jumper holes on the antenna were also changeable and helped as well.  MFJ has a nice manual for band setups, but be sure to adjust for best SWR.  Very easy to do and works great.

The 20 meter band was also a big success and I was very pleased with the performance of the MFJ 1899T antenna.  Thanks for all the previous discussion of the similar antennas that inspired me to take out my antenna.

The end result was 19 contacts, all CW in about 45 minutes on a beautiful day!

Thanks to all my chasers and QRP rocks!

QRPp POTA: How many hunters can I possibly log with only 100 milliwatts–?

6 Comments

As I walked out the door on the morning of Tuesday, March 21, 2023, I grabbed my Elecraft KX2, MM0OPX 40 meter end-fed half-wave, and a key I hadn’t yet taken to the field: my Bamakey TP-III!

I had a full day of errands, appointments, and carting my daughters to/from school, but I also had a good 90 minute window to play radio!

As I’ve mentioned previously, the Vance Birthplace (K-6856) is incredibly convenient this particular school term. I pass by it twice a week, and I feel incredibly fortunate because it’s a wonderful POTA site with POTA-friendly staff. They all know me quite well there at this point.

The Vance site is a small park and the only negative (from the point of view of a POTA activator) is if you have poor timing, you might arrive only to find that a large school group has taken over the site. This is especially a concern on weekdays during school hours–in other words, the time I usually activate Vance.

I pulled into the Vance site that morning and there were no vehicles there other than park staff. A good sign so far!

The only appropriate spot to activate at Vance (if you operate a portable HF station) is in or near the picnic shelter. The rest of the site is where visitors wonder through the old homestead and take guided tours.

I never set up my station in the middle of park activities or in a viewshed.

At the end of the day, we represent all Parks On The Air activators and the amateur radio community at large when we’re in public spaces. The last thing we want to do is detract from others’ park experience.

Before pulling any gear out of the car, I walked into the visitor center and asked the park staff for permission to set up in the picnic shelter. I always do this because if a school or tour group is scheduled to visit the site that day, they almost always need the picnic shelter and have it reserved.

Fortunately, no one had scheduled the picnic shelter, so the park ranger told me, “It’s all yours! Have fun!”

Proper POTA Flea Power!

I like shaking up each new activation in some small way so that it’s not a carbon copy of any previous activation.

Since, like most POTA activators, I visit the same local parks the bulk of the time, it adds a little extra challenge and fun to try different gear combinations, experiment with new antennas, or even (as in this case) try different power settings–!

Propagation changes make for a relaxed 17 meter POTA activation at Pilot Mountain State Park

5 Comments

On Saturday, February 18, 2023, I had a rare opportunity: a full day to play radio.

Instead of doing a five park POTA rove, I chose instead to do a summit activation followed by a park activation.

I published the summit activation on Moore’s Knob (W4C/EP-001) a couple weeks ago and planned to immediately follow that up with this report from my POTA activation at Pilot Mountain State Park (which I activated the same day).

In the process of moving my videos from the camera, to my laptop, and then to PC where I do my remote uploads (my bandwidth at the QTH is far too poor to upload large videos) I somehow managed to delete this particular video file.

I was quite frustrated, actually, because this particular POTA activation was challenging. Lately, I’ve had so few examples of just how quiet a band can be when propagation is less stable.

The SOTA activation I performed only a few hours earlier had some of the deepest pileups I’ve ever experienced. By the time I started my POTA activation a couple hours later, all of this had changed–at least on the bands above 20 meters and I’d chosen 17 meters (a WARC band) since a contest was in progress on 20 and 40 meters.

I’m incredibly pleased that I stumbled upon the raw video files on my backup drive. I was able to reproduce the video in its entirety.  I’m so pleased it wasn’t lost!

This is why it’s a little out of sync date-wise with my other reports.

I hope you enjoy this field report:

Pilot Mountain State Park (K-2750)

After capping off a beautiful 4+ mile hike and SOTA/POTA activation at Hanging Rock State Park, I put my SOTA pack in the car and drove 30 minutes to Pilot Mountain State Park.

It being a gorgeous Saturday afternoon, the park was so full of guests the parking lot was completely full.  A park ranger had incoming cars form a line and he allowed cars in as guests departed one by one. When I arrived, there were five cars in front of me. I was very tempted to do a three-point turn and head back down the mountain to the visitor’s center to do the activation. There was plenty of parking there. Continue reading Propagation changes make for a relaxed 17 meter POTA activation at Pilot Mountain State Park →

Huge 30 Meter Pileups: Beautiful day for a SOTA & POTA Activation at Hanging Rock State Park

1 Comment

There are a few reasons I love Summits On The Air (SOTA):

  1. I love hiking.
  2. I love going truly portable with my radio gear; packing an entire minimalist station in my backpack along with first aid supplies, water, and a bite to eat, then hitting the trail.
  3. I love the views.
  4. I love the sense of accomplishment (hiking to a summit doesn’t happen every day).
  5. I also love that post-hike feeling–my body telling me, “Hey, T, thanks for doing something today!“

No kidding: If I could, I would do a SOTA activation at least twice a week. Maybe when I retire, I will.

Living in the mountains of western North Carolina, I have no shortage of summits to activate–indeed, one is within (strenuous) hiking distance of my QTH.

So why don’t I activate more summits?

It’s because they are much more difficult to fit in my active schedule.

You’ll notice that the bulk of my POTA activations take place within a one hour window of time. This includes set-up, on-the-air, and pack-up time. The brilliant thing about POTA sites is that they’re so accessible in my weekly travels. (Plus, I absolutely love POTA too!)

My average SOTA activation, on the other hand, requires at least a three hour window of time. In fact, it’s usually much closer to four or five hours.

The view from Dogback

Drive-up summits like Anderson Mountain and Dogback Mountain are the exceptions. There’s no hiking time involved, so they are pretty easy to fit into my schedule.

On Saturday, February 18, 2023, a rare thing happened: an entire day opened up for me to play radio. The only real obligation I had was to set-up and participate in a live stream with Josh (KI6NAZ) on the HRCC channel that evening.

At first, I thought about doing a five park POTA rove, hitting four parks and one game land all that eight hour window of time. It was very doable and I knew it would be fun.

But then again, park roves allow very little time for hiking–typically, they’re wham-bam style short activations.  It was also a gorgeous day weather-wise so I scrapped the idea of a POTA rove. (This time!)

Instead, I had a hankering to do a SOTA activation and hike. I took a quick look at SOTL.as and remembered how much I enjoyed my last activation of W4C/EP-001 (Moore’s Knob) at Hanging Rock State Park (K-2753). And hey! It’s both a SOTA and POTA site!

It’s been nearly two years since I’d visited Hanging Rock SP because it’s a two hour drive in a direction I rarely travel.

Hanging Rock  a beautiful park and I truly enjoyed the hike to Moore’s Knob.

As a bonus, Hanging Rock State Park is less than a 30 minute drive to Pilot Mountain State Park. I knew I’d have time in the schedule to do activate both sites! Score!

Hanging Rock State Park (K-2753)

I pulled into Hanging Rock that morning and made my way to the parking area by the lake.

Since it had been nearly two years, I consulted the hiking trail map at the trail head to confirm I was taking the correct loop (Moore’s Wall Loop). Continue reading Huge 30 Meter Pileups: Beautiful day for a SOTA & POTA Activation at Hanging Rock State Park →

Breaking in the new Elecraft AX2 during a short POTA activation

6 Comments

As I mentioned in my recent AX1 vs AX2 video and blog post, I purchased an Elecraft AX2 antenna and bi-pod in late January (note: two days before Elecraft announced their February ’23 sale price! Doh!).

I received the AX2 package a few days later and I was certainly eager to take it to the field.

My first opportunity came on Tuesday, February 14, 2023, when a short activation window opened up in the afternoon.

Zebulon B. Vance Birthplace (K-6856)

One of the first things I noticed after taking the AX2 out of the package is just how solid and compact it is. The AX1 is short, but the AX2 is a few inches shorter because the base is more compact.

Unlike the AX1, the AX2 is a mono band antenna, thus the coil only needs to accommodate one band. When you receive a new AX2, it’s configured for 20 meters out of the box, but the user can modify the coil to work anything from 20 to 6 meters.

“Resonant-ish”

Even though I mentioned this in my AX1 v AX2 article and video, I’d like to reiterate that the AX2 is nearly-resonant on 20 meters. It is not reliably resonant.

I’ve still been receiving a lot of messages from readers stating that their AX2 and AX1 are resonant on 20 meters, so they don’t pack any sort of matching device in their field kit. They simply hook the AX2 up to their little QRP radio and hop on the air.

While it’s true that these antennas may provide an acceptable SWR most of the time, you really can’t rely on a solid, reliable match as you could with an end-fed half-wave.

I’ll repeat what I mention in a previous post:

Small verticals like the AX1 and AX2, that use coils to electrically “lengthen” the antenna, have a higher Q than, say, a large aperture quarter or half wave antenna. In practical terms, this means that the window of resonance is narrow and more fickle than, for example, an end-fed half-wave.

A lot of factors can affect the SWR on higher-Q antennas like the AX1/AX2 including:

      • the type of terrain,
      • height off the ground,
      • length of counterpoise,
      • configuration of counterpoise,
      • and, most notably, the operator’s own body capacitance.

You may find that the AX2, for example, is natively resonant on 20 meters at one location, but isn’t at another location. This is quite normal. It’s also the reason why Elecraft states that both antennas are designed to be used with an ATU.

So there you go! If I hook up my AX1 or AX2 to a radio, I’ll always have some means of matching the impedance–either an external ATU, or a capacity hat. You can also tinker with the length of the telescoping whip and counterpoise to tweak the match.

The important part–especially if pairing these antennas with a radio that lacks both an internal ATU and SWR meter (say, the MTR-3B, G106, or TR-35)–is that you’ve some means to check the SWR before conducting a long activation session.

Gazebo Portable! A quick hike and speedy QRP POTA activation with the Elecraft KX2 and a 28.5′ random wire

6 Comments


On the morning of Friday, February 3, 2023, I wanted to fit in a quick hike and activation as I made my way back to the QTH.  Tuttle Educational State Forest (K-4861) is my go-to when I want to hike and play radio but don’t have enough time to fit in a proper SOTA activation.

That morning, the park was very quiet–mine was the only car in the parking lot. This being an educational state forest, they tend to get large groups of visitors all at once (typically, bus loads of school kids). In the winter, however, the park is quiet because their restroom facilities and water points are all winterized.

I grabbed my SOTA pack–which contained my Elecraft KX2 field kit, Tufteln/N0RNM folding knee board, and a throw line–then hit the trails!

Although it was a windy day, I headed to the gazebo at Tuttle (one I’ve used for activations in the past) which is on a hill and has a brilliant view of Grandfather Mountain.

Trust me, Grandfather Mountain is out there, my iPhone just can’t easily capture it:

The only issue with the gazebo is that the trees behind it are short and very dense with branches. In the past, I’ve launched a line over the top of the tree, but it’s not easy because then there’s always the possibility your throw weight will land on the roof of the gazebo. You also need a 10oz or heavier throw weight on trees like this, else risk getting your line caught in the tree.

There are a number of pines immediately behind the smaller ornamental trees, but to get to those, I’d need to lay my feedline across a service road the park staff use regularly, so that’s a no-go.

Speedy POTA: An impromptu post-hike activation with the Elecraft KX2 and AX1

17 Comments

On Friday, January 27, 2023, I dropped off one of my daughters at the library for a creative writing session.

Hazel was along for the ride, so we decided to hike on the nearby Mountains To Sea Trail (MST) while my daughter was in the meeting.

During the hike, I realized that I should have taken my field radio pack along because it would have been so easy to activate both the MST and Blue Ridge Parkway as a two-fer.

Instead, Hazel and I enjoyed our hike and got back to the car with about 35 minutes or so to do an activation–including set-up, on-air time, and pack-up.  That would leave me just enough time to pick up my daughter at the library before they closed for the day.

Challenge accepted!

Because I had been using the Elecraft KX2 and AX1 recently, I had both packed in my Spec-Ops EDC backpack.  In theory–even filming a video at the same time–I knew I could probably fit in a whole activation with 25 minutes on the air. I only needed 10 contacts, and I’ve never been in a situation where the AX1 couldn’t achieve that goal.

Hazel and I grabbed my bag from the car, I started recording a video, and we made out way to the nearest picnic table at the Blue Ridge Parkway HQ parking lot! Continue reading Speedy POTA: An impromptu post-hike activation with the Elecraft KX2 and AX1 →

KX2/AX1: Second quick activation of the day at Lake James State Park!

2 Comments

As I mentioned in my previous field report, on Saturday, January 21, 2023, I had just enough time to activate two parks in short order on the way back to my QTH

I thought it might be fun to perform both of these activations with the Elecraft KX2 and AX1 combo because they’re so speedy to deploy.

Once again, I wanted to show the whole KX2/AX1 set-up and pack-up process in my activation video.

Lake James State Park (K-2739)

As I pulled into the Lake James Catawba River access, I discovered that there were few other guests there that day. I was expecting more people on a Saturday especially since the weather was so pleasant and South Mountains had been so busy earlier that morning.

Then again, the Catawba River access always has less visitors than the Paddy’s Creek area (which is really the main public access point for Lake James).

I pulled into a parking space, found one of the closest picnic tables, and set up the station in short order.

At South Mountains State Park, an hour earlier, I performed the entire activation on 20 meters. To shake things up a bit, I decided to perform the one at Lake James on 17 meters (note here that the AX1 only works on 20 and 17 meters unless you have the coil which adds 40 meters).
