QRP SOTA: Lee pairs the KH1 and MPAS 2.0 to activate High Willhayes (G/DC-001)

Many thanks to Lee (M0VKR) who shares the following field report and video:


SOTA CW Activation on High Willhayes Dartmoor

by Lee (M0VKR)

It was an overcast and breezy morning when wife Joanne and myself Lee, M0VKR set out on our latest SOTA (Summits on the Air) activation adventure. Our destination was High Willhays, the highest point in Devon UK – SOTA G/DC001, Dartmoor is well known for its rugged beauty and challenging terrain.

We parked the car a short distance up the road from the army camp, slung our packs over our backs and set off. The gravel tracks leading to the summit stretched out before us and took a winding path through the moorland.

A few sheep and cattle grazed in the rough grass as we made our way upwards on the gentle slope. It was a breezy morning and we had had rain a short while earlier. Despite the weather our spirits were high, and we were eager to reach the top and get on the air with the Elecraft KH1.

In my pack was my now trusty Elecraft KH1 and an MPAS 2.0 vertical antenna, with the KX3 as backup, a reliable setup for such expeditions. I’m pretty sure I could halve the weight in my pack, but as it’s not a huge walk to the summit I don’t mind ferrying the extra gear to the top. The weather, though overcast, was adding a touch of drama to the landscape, and the breeze kept us cool as we trekked upward.

Joanne, ever the supportive partner, helped carry some of the cooking equipment and victuals and she kept the mood light with her cheerful conversation.

After a brisk hike, we reached the summit of High Willhays. The view, even under the Grey sky, was breathtaking. Rolling green hills and expansive moorland stretched out as far as the eye could see.

I set about preparing the station, using the MPAS 2.0 vertical antenna, which is quick to deploy and ideal for the variable conditions we faced. Despite the less-than-ideal propagation conditions, I was determined to make the activation a success.

Although the MPAS in vertical form isn’t very efficient on 40, I prefer to take advantage of the quick setup that it offers, one of these days I will look at adding a top section to make 40 more efficient, perhaps as a sloping inverted L or something similar, more reading of the manual required!

With everything set up, I made the first call on the 40m band. My Friend Matt MW0KAX answered, he was essentially line of sight from Wales, so his signal was strong. That was the first and last contact on 40m. I changed to 20 meters, where the MPAS was more efficient for the little KH1 and it was able to breathe a bit easier. The tuner in the KH1 is nothing short of amazing, and quite happily tuned 40 meters in a few seconds.

The static crackled, and for a moment, there was silence. Then, a faint reply came through. The thrill of making that first contact was palpable. It still amazes me every time I make those first few contacts that QRP does work, even with a compromised antenna system. Despite the challenging conditions, My limited skill, Plenty of luck and the reliability of the equipment began to shine. All the equipment I was using was off the shelf, I hadn’t made a single thing myself, maybe one day.

One by one, contacts started to come in. Each short QSO contact was a small victory, a testament to perseverance and the joy of ham radio. It is necessary to persevere as a newer CW operator and use QRP power levels and poor propagation conditions. It’s non-negotiable after driving for 2 hours, and a 4km hike that we go home empty handed. I logged each contact meticulously, my excitement growing with every successful connection. Joanne watched on slightly bemused but very supportive of the hobby, sharing in the triumphs that each contact brings and providing much-needed encouragement.

By the end of the activation, We had made several QSOs. While the propagation conditions had been far from ideal, the activation was undeniably a success. We had achieved what we set out to do: connect with fellow hams across the airwaves from the summit of High Willhays for a SOTA activation.

As we packed up our gear, the breeze picked up, and the clouds began to clear slightly, offering a glimpse of blue sky. The trek back down was filled with reflections on the day’s achievements and plans for future activations. We both felt a deep sense of accomplishment. We had braved the elements, navigated the challenging RF conditions, and emerged victorious.

This activation, like many before it, was a reminder of the joys of ham radio, CW and QRP operation and the adventure it can bring. For me and my wife Joanne, High Willhays would always hold a special place in our memories, not just for its height, but for the heights that we reached together on the airwaves.

From the Activation Archives: Pairing the Elecraft KX2 and MPAS 2.0 at Babcock State Park

In May 2022, my buddy Eric (WD8RIF), his son Miles (KD8KNC), and I opted to skip Hamvention that year and, instead, plan an extended weekend POTA campout in West Virginia.

Although attending the 2022 Hamvention was a tempting idea, I had already committed to a two-month family camping trip to Québec, Canada, scheduled to begin just a week later. Fortunately, the camping trip provided us with ample opportunities for field radio and was a more budget-friendly alternative.

During a recent review of my videos, I uncovered two videos from my West Virginia journey that had previously remained unpublished.

Amidst the hustle and bustle of Hamvention 2024 (happening now), I’ve decided to shake things up by publishing these two videos. With my schedule packed to the brim during Hamvention weekend, I’ve arranged for these posts to go live automatically.

Abbreviated field report

Indeed, as I prepare this report, I’m only two days away from heading to Ohio and I’m pressed for time. In lieu of my regular in-depth field report, I’m keeping these two reports simple and short so that I can fit them in my tight schedule.

Babcock State Park (US-1798)

My second archived POTA activation is from Babcock State Park where Eric, Miles, and I (along with Theo the dog) actually camped for several nights.

On the final day of our West Virginia “RATpedition”–Sunday, May 22, 2022– we set up at the Sugar Run Camp Picnic Area. This particular picnic site is quite large and we had the place all to ourselves that morning.

Watching the activation video now, I remember how much I loved the dry-stacked stone picnic shelters.

As I say in the video, I’d love to build something like this at my QTH!

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:

Looking Back…

It’s so much fun reviewing these activations from nearly two years ago. We faced similar propagation challenges as we have recently (mid-May 2024), with numerous CMEs impacting our planet.

During some of the previous activations, we struggled to log even 10 contacts. In contrast, I’m pleased to have logged a total of 15 contacts during this activation. Although it was slow-going, it was a significant improvement over previous attempts.

Watching the video reminded me of my love for camping in West Virginia. We might consider organizing another WV RATpedition soon.

Thank you!

Thank you for joining us during this 2022 activation!

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!

From the Archives: A 2022 Postcard Field Report and Activation Video from New River Gorge National Park

These are busy days for K4SWL

These past few weeks have been absolutely crazy for me in terms of activity–I’ve been traveling a lot, doing (involved) DIY projects on the house, searching for a new car, planning a PV system for the QTH, fixing well pumps, helping friends, and doing caregiving for my folks.

It’s all kept me very busy!

I have a sizable backlog of emails that have accumulated during this time. If you’ve sent me a message, I likely haven’t read it yet. Apologies for that. I simply haven’t had time to read and reply.

I thought about skipping a field report this morning, then I remembered an amazing West Virginia camping trip and draft videos I’d already uploaded to YouTube.

In lieu of writing a full field report (and so that I can share a video today) I thought I’d simply share this activation video with a Postcard type field report.

2022 West Virginia POTA Camping Trip

Last year (2022), in lieu of going to the Dayton Hamvention, my buddies Eric (WD8RIF), his son Miles (KD8KNC), and I spent a long weekend activating parks and camping in the New River Gorge area of West Virginia. Click here to read more about that trip.

The camping trip was absolutely amazing and we activated a number of parks during that time.

I made activation videos at most of the parks we visited, but with my summer travels and activations in Canada last year, I skipped over several of the videos I’d uploaded so that I could publish my Canadian activations while I was still in Canada.

New River Gorge National Park (K-0696)

 

The following activation video was made on May 21, 2022 as WD8RIF and I activated K-0696.

 

I’ve yet to re-watch this video myself, but I remember clearly that this particular day we had atrocious band conditions.

Indeed, rough bands were present during much of our weekend camping trip, but it never stopped us from having fun or activating our parks.

In terms of gear, I used my trust Elecraft KX2 paired with my Chameleon MPAS 2.0 antenna system.

POTA Field Report: Attempting to deplete the Xiegu X5105 internal battery at Lake Norman

Each time I head to a park or summit, I have a goal in mind.

With summits, it’s getting to the summit and activating it because, sometimes, that can be a challenge in and of itself. I’m not exactly Sir Edmund Hillary, so I’m happy when I make it to the top of any summit!

Parks, however, offer me the chance to experiment with transceiver/antenna combos, test gear, and explore hikes. Parks tend to be more accessible and spacious than summits and even have shelter options if weather is questionable.

I don’t even attempt afternoon summit activations if they require a decent hike and there’s a good chance of pop-up thunder storms.

On Monday, June 7, 2021, it was hot and incredibly humid in the Piedmont of North Carolina. That early afternoon, little patches of showers were passing through the region delivering brief, isolated downpours.

The weather forecast also predicted a high likelihood of thunderstorms that afternoon. (Turns out, they were correct.)

Those were not conditions for a SOTA activation, rather, I decided to pick out a park I knew could offer up some shelter options. Lake Norman was an obvious choice–there’s a very nice covered area at their visitor’s center and also two large picnic shelters at the other side of the park. Lake Norman it was!

Goal

I drove to Lake Norman State Park with one goal in mind: deplete the Xiegu X5105 internal battery. I had assumed the battery would only power the X5105 for perhaps two activations on one charge.

Boy, was I wrong.

I charged the X5105 before this activation on May 17, then I completed this short activation on May 18. I never expected the battery to keep going, but it did.

Now three full weeks later, I decided I would deplete the battery at Lake Norman because that afternoon I had a decent amount of time to play radio in the field. In my head, I was prepared to squeeze perhaps 30-45 minutes more air time out of that one May 16 battery charge.

Lake Norman (K-2740)

I arrived at Lake Norman State Park and scouted out a site. Fortunately–it being a Monday in the early afternoon–it wasn’t busy and all three shelters were available.

I chose to set up at a shelter at the far end of the main picnic area.

Gear:

The humidity was so thick that day,  I was sweating just walking around the site. I noticed in my activation video (see below), I was breathing as hard as I would hiking to a summit even though I was just tooling around the picnic shelter.

I had no doubt in my mind that if a thunderstorm developed, it would be a doozie! (I was right about that, too–keep reading.)

On The Air

I paired the Xiegu X5105 with my Chameleon MPAS 2.0 mainly because I wanted to see how easily the X5105 ATU could match this multi-band vertical. Turns out? Quite easily.

I expected the X5105’s battery to deplete to the point that I would need to use an external power source to complete the activation, so I connected my QRP Ranger battery pack, but didn’t turn it on. I knew that when the radio died, I could flip the QRP Ranger’s power switch and perhaps only lose a few seconds of air time.

I hopped on the air and started calling CQ. I planned to operate the X5105 until the internal battery died, then (if needed) continue operating with the QRP Ranger until I logged my 10 contacts for a valid activation. Post activation, I planned to hike one of the Lake Norman loop trails.

Normally, I would mention the number of contacts I made perhaps noting the bands that were most productive. Instead, if you’d like to experience this activation with me, you might consider watching the activation video.

Video

Here’s my real-time, real-life, no edit video of the entire activation including my full set up.  My summary of the activation follows–keep scrolling if you’re open to a spoiler.

Please note that this is the longest video I’ve ever published, so don’t feel any pressure to watch it in its entiretity:

Impressed

Let’s just say that the X5105 sold me.

The activation was incredibly fun and I logged 20 stations (18 CW and 2 phone) from Alaska to Spain with my 5 watts and the MPAS 2.0 vertical.  Propagation conditions were only “meh” but since I had the time to play radio longer, I was able to take advantages of little openings as they happened.

X5105 Battery

The X5105 won.

I simply gave up on trying to deplete the internal battery because I was running out of time to fit the activation and a much needed hike that afternoon before thunderstorms moved in.

I operated over 90 minutes with constant CQ calls and the battery never made it below 10.2 volts.

A most welcome surprise.

No mic, no problem!

During the activation, I remembered that I had been asked by readers and viewers to include more SSB work.

Problem was, I left my X5105 mic at the QTH (nearly 2 hours away by car).

I remembered though that, like the Elecraft KX2, the X5105 has a built-in microphone.

I decided to give that mic a trial by fire and, by golly, it worked!

Not only did it work, but it worked well.

The X5105? A keeper.

It was at Lake Norman that day, I decided the X5105 was a keeper.

That evening, I reached out to Radioddity–who lent this X5105 to me–and offered to pay full retail price for it either in cash or via ad credit

Since Radioddity is a sponsor on my other radio site–the SWLing Post–we decided that, since their ad was coming up for renewal soon, I would simply extend their ad time an equivalent amount of months as the full value of the X5105 ($550 US). This saved them from having to cut a check in two months.  Worked for both of us.

I have much, much more to say about the X5105 and will do so in an upcoming review.

In short, though? It’s not a perfect radio by any means, but I feel like it really hits a sweet spot for the QRP field operator.

I enjoy putting it on the air and it’s an incredibly capable little transceiver.

I’m very pleased to now put it in rotation with my other field radios. Look for it in future reports!

QSO Map

Here’s the QSO Map for this activation (click to enlarge):

Hike and dodgy weather

After packing up my gear, I walked over to a nearby trailhead and checked out the trail map. I was prepared to take a very long hike that afternoon despite the heat and humidity, but I also knew conditions were ripe for a thunderstorm.

I decided to take what appeared to be a fairly short loop trail along the lake. Looking at the map, I assumed the trail might be 1 mile or so long.

The hike is well-worn and well-marked, so there’s no getting lost here. That’s one of the reasons I didn’t bother looking at my GPS map or even consulting the trailhead map in detail.

Instead, I simply started hiking the Lake Shore Trail loop. It was gorgeous. Here are a few photos (click to enlarge):

The skies started getting dark, though, and I heard a little distant thunder.

I decided it might make sense to consult my phone for the weather map.

A line of thunderstorms had developed and they were sweeping toward me. Time to pick up the pace of hiking!

It was at this point I realized I had underestimated the length of this loop trail. Part of me was quite pleased that it was longer than I anticipated, but the part of me that didn’t want to be caught out in a t-storm wanted to get back to the car ASAP.

I checked another weather map a few minutes later.

I decided that jogging the rest of the trail made sense!

Turns out the 1 mile loop was something closer to 3 miles when I included the walk back to the car.

I did make it back to the car in time, though, right before the heavens opened.

It’s no exaggeration to say that I was sincerely concerned about the possibility of tornadoes in that storm front.

The skies were dark enough that streetlights turned on and the rain was incredibly heavy with strong wind gusts. I saw flash flooding and driving conditions were nearly impossible. I parked next to a brick building in the town of Catawba and waited for the strongest part of the storm to pass. I was also very grateful I wasn’t still on the trail by the lake!

Of course, the storm passed and I expected conditions to be a little drier behind that front, but I was wrong. I think the humidity level increased to 150%. Ha ha! No worries, though, as I was on my way to air conditioned space!

Thanks so much for reading this field report and stay safe out there!

73,

Thomas (K4SWL)

Pairing the TX-500 and MPAS 2.0 on a beautiful morning activation of the Blue Ridge Parkway

On the morning of May 10, 2021, I had a hankering to head to the Blue Ridge Parkway for a quick park activation.

I had a particular spot in mind–one that’s only two miles or so from my QTH as the crow flies. The only wrinkle in my plan was that we were expecting rain all morning and at our house we were in thick fog and light, steady rain.

Normally when I have these conditions, I look for a sheltered site, but I thought it might be a great time to take out the TX-500 since it’s weather-resistant. Why not, right?

I packed the lab599 Discovery TX-500, my Chameleon MPAS 2.0 vertical, and my Elecraft T1 antenna tuner to pair the two. I also brought along some rain gear.

Although the activation site is close to home as the crow flies, it actually takes about 30 minutes to drive there. By the time I reached the site, the skies were mostly clear and the sun was shining! This time of year, it reminds me of living in the UK: if you don’t like the weather, just wait five minutes.

Gear:

On The Air

This was very much a road side activation. The spot I chose isn’t an overlook–although it did provide amazing views–it was simple a pull-off.

This is where antennas like the MPAS 2.0 are so useful: they are self-supporting and very quick to deploy. Since I was set up right off the road, I also appreciate using verticals rather than wire antennas since the antenna and throw line aren’t in the way of others who might choose to park in the same pull-off.  I can easily deploy the counterpoise and feedline so that it’s out of the way.

As with most park activations, I started on 40 meters CW and only operated 5 watts.

I quickly racked up five contacts on 40 meters, then the band fell silent.

I moved up to 30, then 20, down to 80, back to 60 and 40 again.

About 30 minutes had passed since I was last on 40 meters, so new hunters were checking the bands. I snagged a total of seven more contacts in about eleven minutes.

Obviously, 40 meters was the only band open that morning!

A quick note about 80 meters

I get a lot of questions from readers and YouTube subscribers about my use of the 80 meter band during the daytime.

I go into more detail about this in the video, but contrary to what many think, 80 meters can be a very useful daytime band for POTA activators.

While it’s true that you’re not going to work DX on 80 meters during the daylight hours (else, highly unlikely), you can still work local and regional stations.

Keep in mind that POTA, WWFF, and SOTA activations aren’t about working DX. DX is fun and perhaps a personal goal, but it has nothing to do with success in achieving a valid activation.

Basically, any contacts–DX or local–will get you what is needed for a valid activation.

If, like me, you live in a part of the country where there are a concentration of park and summit hunters/chasers within a daytime 80 meter footprint, then hop on that band and give it a go!

I’m not sure how useful this might be for activations in sparsely populated areas like Montana or the Dakotas, for example, but along the east and west coast, 80 meters is your friend.

At this particular activation, I didn’t didn’t employ an efficient antenna for 80 meters. While I’ve made numerous 80 meter contacts on the CHA MPAS 2.0 in the past, it’s just not physically large enough to be efficient on that band.  The CHA Emcomm III Portable or another long wire antenna would have provided better results. But I knew that 40 meters and possibly 30 meters would be my best bet that day, so the MPAS 2.0 was a great choice.

Again: don’t forget about 80 meters. It’s helped me snag many an activation!

Video

Here’s my real-time, leal-life, no-edit video of the entire activation:

Click here to view on YouTube.

You might hear an audio pop when I’m keying on the TX-500. This is happening because I have the audio gain cranked up all the way for the video. While the speaker/mic can get quite loud, when I’ve got it located so far from the camera mic, I run it at 100% volume to be heard. I recently changed my CW T/R recovery time from 100ms to 400s which eliminated most of the audio popping.

Thank you for reading this field report! I hope you’re getting an opportunity to take your radios outdoors this week!

Activating Elk Knob State Park for SOTA, POTA, and WWFF

On Monday, March 8, 2021, I had a very rare opportunity: nearly a full day to play radio!

I debated where to go the night before and I had a lot of ideas. Do a multi-park run?  Activate some new-to-me parks a little further afield? Hit a SOTA summit?

While it was very appealing to plan a multi-park run for POTA/WWFF, I really wanted to stretch my legs and activate a summit. The weather was glorious and it dawned upon me that we’ll soon be entering the season of afternoon thunderstorms which will, no doubt, have a negative impact on my summit plans for the next few months since afternoons are typically when I have time to do activations.

After examining the map, I decided to go to Elk Knob State Park. The summit of Elk Knob is a SOTA site and the park is in both the POTA and WWFF programs.

Last year, I activated Elk Knob State Park and really enjoyed the experience.

The round trip hike to the summit (adding in a little trail loop around the park) would amount to about 4 total miles and an elevation increase of roughly 1,000 feet.

Monday morning, I left the QTH around 9:00 and arrived at the park around 11:15–it was a proper scenic drive.

The 1.9 mile hike to the summit took me about 45 minutes. The path was amazingly well maintained: 4′ wide with crushed stone most of the way.

One of the nicest trails I’ve been on in ages–Elk Knob State Park is quickly becoming one of my favorite NC State Parks.

There aren’t any antenna-friendly trees on the summit, so I was happy that I packed the Chameleon MPAS 2.0.

At first, I planned to only bring the top section of the MPAS 2.0 vertical to save space, but the hike was so short, I brought the lower aluminum sections as well. I’m glad I did.

Deployment of the MPAS 2.0 was quick and I the Elecraft KX2‘s internal ATU found a match on 20 meters very quickly.

Elk Knob (W4C/EM-005)

I spotted myself using the SOTA Goat app and received quite a 20 meter CW pileup! As you’ll see in my video below, it was testing the limits of my CW skills for sure.

With 5 watts, I quickly worked stations to my east in France, Spain, and Germany, and to my west all over the west coast of North America. It was a hoot!

I eventually moved to 40 meters and operated a bit, but 40 was suffering from poor propagation so stations that are normally quite strong, were weak that day.

I needed four stations for a valid SOTA activation and 10 stations for a valid park activation. I logged a total of 38 stations in 56 minutes. 75% of those contacts were on 20 meters.

Video

Here’s one of my real-time, real-life videos of the entire activation (less a small amount I removed while eating a quick bite):

When people tell me running QRP is like “trying to play radio with both hands tied behind your back” I’ll show them this video. 🙂

AGN?

While the hike, the weather, and the signals were all in my favor, I’ll admit I wasn’t on my “A Game” that day. We all have days like this where we struggle to copy, to keep up with the flow of contacts, and to send correctly.

In recent weeks, I’ve gotten a number of emails from readers and viewers who said they had a less-than-smooth SOTA or POTA activation and felt a wee bit embarrassed on the air when they struggled copying.

But you know what?

No worries!!!

This is all about having radio fun in the field, enjoying a hike, taking in the views, and soaking up the beautiful weather! It’s not a contest and we have nothing to prove to anyone.

I can also promise you that any chaser/hunter who has ever activated a field site will completely understand if they have to send their call a couple extra times or if they (heaven forbid!) have to re-send their call after you incorrectly copy a character.

This is totally normal.

Be easy on yourself and enjoy the ride. Even on days when I don’t feel like I’m 100% in the groove, I find doing a summit or park activation clears my mind and resets my soul.

My policy? When a mistake is made laugh it off and move on!

SOTA Field Report from Rocky Face (W4C/WP-006)

One of the things I love about POTA and now SOTA is that it gives me a reason to venture out and explore parks and other public lands that might have otherwise never shown up on my RADAR.

Rocky Face is a prime example.

On the morning of Wednesday, March 10, 2021, I would have never guessed that by noon I would be standing on the summit of Rocky Face. That morning, I had planned to activate the summit of Baker’s Mountain–a park and summit I know very well as I’ve hike the trails there almost monthly and the mountain is a stone’s throw from my parents’ home.

That morning, when I arrived at Baker’s Mountain Park and the gates were shut, I remembered that they are closed on Wednesdays.

Oops.

I was determined to hike to a summit, though, so I grabbed my iPhone and launched the SOTA Goat app, then searched for nearby summits.  That’s when I noticed Rocky Face which was *only* a 40 minute drive from Baker’s Mountain. I had heard of this 1 point summit and park, but had never been there, so why not take a little road trip and explore?

Rock Face (W4C/WP-006)

View of Rocky Face from the road.

It was a very pleasant drive which was made all the better by gorgeous sunny weather.

When I arrived on site, I was surprised to see just how well developed this park was. There were two different parking areas, a visitor’s center, picnic area, rock climbing face, playground, and numerous trails. There’s even a large area for outdoor events.

I took the “Vertical Mile Challenge” to the summit (which I would recommend) and was more of a workout that one might imagine for a 1 point 576 meter summit.

The trail was very well maintained. The ascent up the granite slope offered some welcome views of the surrounding area.

I was a little surprised to find some Nodding Trilliums blooming on the side of, and even on the path. A sure sign spring is on the way!

March 10th was also one of the warmest days of the year so far.

On the summit, there were actually a couple of picnic tables–a total surprise which made this SOTA operation feel somewhat luxurious!

On The Air

I set up the Elecraft KX2 and Chameleon MPAS 2.0 which were still packed from a SOTA activation two days earlier at Elk Knob (I’ll post a report of that activation in the near future).

I had not charged the Lithium Ion pack in the KX2 after the Elk Knob activation, but I assumed I’d still have enough “juice” to get me through the Rocky Face activation at 5 watts.

I started by calling CQ SOTA on 20 meters. A friend told me that propagation was very unstable, so I feared the worst. Fortunately, 20 meters was kicking (40 meters much less so).

Right off the bat, I worked stations in France, Germany, Slovenia, Quebec, Spain, and all of the west coast states of the US. It was so much fun and exactly why I love QRP and playing radio in the field.

As I switched from 20 meters to 40 meters, some hikers passed by. Turns out it was my cousin and her husband–what a surprise! Of course, they had no idea what I was up to, so I ended up explaining not only SOTA, but amateur radio and why I was using CW (yeah, I cut that bit from the activation video below).

They moved on and I hit 40 meters which was hit harder by the poor propagation. Many stations I regularly work were a good 2-3 S units lower in signal strength.

I am certainly looking forward to some stable propagation eventually! Still…very, very pleased with the 24 stations I worked and the QRP DX as well.

Here’s a QSOmap of my contacts–all from 5 watts and a vertical:

Rocky Face turned out to be a fun little hike, productive activation, and a great opportunity to explore a new summit and park. I’ll certainly return!

Poor propagation but impressive QRP DX with the CHA MPAS 2.0 vertical antenna

One of the funny things about doing field activations is you never know what to expect when you arrive on site, setup, and hop on the air. It’s part of the fun, really. There are certain things you can control, and then there’s propagation.

On Sunday, February 14, 2021 (yes, Valentine’s Day), we had a modest break in the weather and my wife and daughters encouraged me to hit the field to do a quick activation before an afternoon movie marathon. Sunday was the first day I had seen the sun at our house since the previous Wednesday when the cloud ceiling descended to the altitude of our house (3,300′ ASL) and stayed there. It also wasn’t raining incessantly on Sunday, which was a welcome change.

I checked with my go-to propagation friend Mike (K8RAT) before heading out the door and he informed me that things were dismal. I wasn’t surprised: earlier that morning I worked a couple CW stations calling CQ POTA on 40 meters who had very few takers.

Still…I wasn’t going to let propagation stop me.

“Damn the torpedoes, full steam ahead.”

I chose the Zebulon B. Vance Birthplace (K-6856) as my POTA site because it’s the closest park to me that has a covered shelter. I fully expected rain to move in within an hour and really didn’t want that to cut my radio play short.

Once I arrived on site, I decided to deploy my  Chameleon MPAS 2.0 vertical antenna. Why would I use a multi-band vertical instead of a more efficient wire antenna on a day with dodgy prop?

Aren’t you a handsome antenna!

For one thing, I had a limited amount of time and the MPAS 2.0 can be deployed and packed up within a few minutes. Also, I could position the MPAS 2.0 close to the shelter so if heavy rain moved in, I could even keep the base of the antenna protected and pack it up under cover. That and I really didn’t want to fiddle with a wire antenna in the rain if I didn’t have to.

Gear:

On The Air

In short: I only made 12 contacts during this brief activation.

But what I lacked in quantity, I made up for in quality!

Let’s skip straight to the QSOmap of the activation. Keep in mind these are contacts made with a vertical antenna and only 5 watts of power (green poly lines are CW, red is SSB):

Days like Sunday we can’t expect large pileups with five watts, but we can expect normal–albeit brief–openings that allow for some serious low-power DX.

My five watts and a vertical caught Raffaelle’s (IK4IDF) attention in Italy. Sure…he has good ears with a nine element HF Yagi, but I worked him with 5 watts over a distance of 7653 km / 4755.36 mi.

951 miles per watt? Yes, please! I’ll take that!

Parks On The Air isn’t really about working DX, but it’s so much fun when it does happen.

Video

I made a video of the full activation which includes setting up the Chameleon CHA MPAS 2.0. As I mention each time, this is a real-time, real-life video so keep expectations low. 🙂 It includes a number of mistakes on my part.

I’m hoping this odd pattern of bad weather will break soon. I shouldn’t complain: I feel pretty fortunate that we haven’t gotten hit hard with some of the heavy winter conditions affecting much of North America right now.

As soon as it dries up a bit, I’m ready to hike to a local summit for a little SOTA (Summits On The Air) fun! I can’t wait…

Pairing the Elecraft KX2 with the Chameleon MPAS 2.0 at Lake James State Park

For the past four days here at my mountain QTH in North Carolina, I haven’t seen the sun. The cloud ceiling has been low and our house has been in the middle of it. It’s been rainy and foggy with temps floating a few degrees above freezing.

Last Tuesday (February 9, 2021), however, we had one day with glorious weather and I’m so pleased I carved out 90 minutes to perform a park activation on my way back home from a short trip.

I picked Lake James State State Park (K-2739) because it’s such a short detour and has numerous spots where I could set up my gear.

The temperature was a truly balmy 60F/15.5C–possibly even a tad higher.

Lake James State State Park (K-2739)

On my way to Lake James, I knew I’d use my Elecraft KX2 (it was the only transceiver I had on this trip) but debated what antenna to deploy. I chose the Chameleon MPAS 2.0 vertical antenna because, to my knowledge, I had never paired it with the KX2 and I enjoy shaking up my transceiver and antenna combos.

Gear:

The brilliant thing about antennas like the CHA MPAS 2.0 is how quick they are to deploy: it takes me all of three minutes or so.

On the air

Since the Elecraft KX2 has a built-in battery and built-in ATU, I basically connected the radio directly to the antenna and was on the air in moments.

The CHA MPAS 2.0 is the vertical equivalent of a random wire antenna: it’s not resonant on any one frequency and requires an antenna tuner to achieve a good SWR.

As I mentioned in the video (below) I always keep my expectations low when deploying a vertical antenna in areas like western North Carolina where ground conductivity is poor.

Maybe the antenna decided to prove me wrong, because I hopped on 20 meters CW and logged a number of stations across the country including Washington state and British Columbia with a measly five watts.

It also happened that my buddy and fellow POTA activator, Steve (KC5F), was just down the road activating another site in the same county. It’s rare that Steve and I can work each other because, typically, we’re too close for skywave propagation and too far for ground wave. Not this time! We were close enough for ground wave on multiple bands–it was great fun working him park-to-park on every band I tuned.

I moved from 20 meters to 17 meters, to 30 meters, 40 meters and back up to 20 meters SSB.

The great thing about using the MPAS 2.0 is how incredibly easy it is to pick up and move from band-to-band–there’s no manually tuning a coil or changing links on a multi-band diplole. In fact, the MPAS 2.0 covers 160-6 meters, so I’ve lots of options if band conditions are wonky.

Here’s an unedited video of the entire activation:

In the end, here’s how my QSOmap looked with 32 stations logged:

I look back at activations like this and am reminded of the magic of HF radio. It’s truly phenomenal, in my mind, that with less power than it takes to light an LED bulb, I can make contacts across the continent pretty effortlessly–CW or SSB–even during the solar doldrums! Good fun!

In other news, my ankle is healing nicely and once this cycle of nasty weather clears, I’m looking forward to putting some SOTA sites on the air!

How about you? Do you have any field radio plans? Has the weather or C-19 lockdowns gotten in the way? Please comment!

POTA Field Report: Activating the BRP with my new-to-me Icom IC-703 Plus

When my buddy Don told me he was selling his Icom IC-703 Plus a few weeks ago, he caught me in a (multi-year long)  moment of weakness. I asked his price and followed up with a PayPal transaction without giving it a lot of thought. It was a bit of an impulse purchase, if I’m being completely honest, but he definitely gave me a “friends and family” discount.  (FYI: Don is the same enabler that made this purchase happen.)

I’m thinking the IC-703 Plus might be a good first HF rig for my daughter (K4TLI) and, of course, it’ll be fun to take it to the field from time to time.

Of course, the best way to get to know a radio, in my opinion, is to take it to the field. So that’s exactly what I did last week (January 13, 2021).

Blue Ridge Parkway K-3378

Against my better judgement, I decided to make a video of the activation. I mean, what could possibly go wrong operating a radio for the first time in the field? Right–?

I picked out an “easy” park for this activation: the Blue Ridge Parkway.

Although most of the parkway around Asheville, NC, is closed to vehicle traffic, the Folk Art Center is open year round and a very convenient spot for POTA.

Gear:

I paired the IC-703 Plus with my Chameleon MPAS 2.0 vertical antenna. I was curious how easily the IC-703’s internal ATU could match the MPAS 2.0: turns out, pretty darn well!

I started the activation on 40 meters phone (SSB).

Almost immediately, I logged a few contacts and that quickly built my confidence that even the default voice settings were working well on the IC-703 Plus.

I then moved to 40 meters CW and used the CW memory keyer to call CQ (I pre-programmed this before leaving the QTH that day).

Then I experienced a problem: when someone answered my call, my keyer didn’t work properly. For some reason, it was sending “dit dash” strings from both sides of the paddle. I’m not entirely sure what happened but assume there was either a radio glitch or a small short in my paddle cable. After fiddling with the IC-703 for a bit, I pulled out my Elecraft KX2 and finished the CW portion of my activation. (Always carry a spare radio, I say!)

Actually, I assumed since I was using the IC-703 for the first time, there could be hiccups as I did not do a full rig reset prior to putting it on the air–settings were essentially what they were when Don had the radio.

Here’s one of my real-time, real-life no edit videos of the entire activation, if you’re interested:

Back home, I connected my CW Morse paddles up to the IC-703 and it worked perfectly. Even though I checked the connections in the field, I must assume one of the plugs simply wasn’t fully-inserted. It hasn’t repeated this since.

Despite the CW snafu, I’m very pleased with the IC-703 Plus so far. I like the size for tabletop operating and it’s actually surprisingly lightweight.

If you own or have owned the IC-703, please comment!
