SOTA in the Clouds: Pairing the Elecraft KX2 and MPAS Lite for brilliant QRP fun on Craggy Dome!

5 Comments

Although I live in the mountains of North Carolina and am surrounded by SOTA summits, it’s much easier for me to activate a park rather than a summit.

Parks can be quite easy: find the park on a map, drive through their main entrance, find a good picnic table to set up, and next thing you know you’re on the air! Of course, wildlife management areas and game lands can be more tricky, but typically you can drive to the activation site.

Summits–speaking as someone who activates in North Carolina–take much more planning. If it’s a new-to-me summit, I typically need to:

  1. find the GPS coordinates of the true summit
  2. map out the drive to the trail head
  3. read through previous activation notes (if they exist) to find out
    • what type of antenna/gear I might pack
    • and any notes I might need to find the trail or bushwhack to the true summit (quite often published, well-worn trails don’t lead to the actual summit)
  4. look up the trail map and make sure I have a paper and/or electronic copy
  5. pack all needed gear for the hike, activation, and emergencies
  6. sort out the time it will take to travel to the site, hike the full trail to the summit, activate, and return home

If you ask most any SOTA activator, they’ll tell you that the planning is part of the fun.

It really is.

One summit I’ve had on my activation list for ages is Craggy Dome (W4C/CM-007). Out of the higher summits in this region, it’s one of the easier ones for me to reach from the QTH. In fact, as with Lane Pinnacle, I could simply hike from my house directly to the summit (although one way to Craggy might take the better part of a day). The trailhead is about a 50 minute drive, and the hike about 30 minutes.

SOTA notes and All Trails indicated that Craggy Dome’s trail isn’t always easy to follow and that it’s steep and slippery.

Craggy has been activated loads of times, though, so I wasn’t concerned at all.

Living here and knowing how much brush there was on the manway to the summit, I knew that Craggy would be a pretty easy summit if I could activate it after the parkway re-opened for the spring and before the mountain “greened-up”; about a five week window.

Meeting Bruce

My schedule opened up for an activation of Craggy Dome on the morning of April 21, 2022 and I was very much looking forward to it.

I wouldn’t be alone on this hike either. Bruce (KO4ZRN), a newly-minted ham, contacted me and asked if he could join me on a hike and simply be an observer during a SOTA activation.

Fortunately, timing worked for him to join me on this particular SOTA activation. Continue reading SOTA in the Clouds: Pairing the Elecraft KX2 and MPAS Lite for brilliant QRP fun on Craggy Dome! →

Dale’s solution for enhanced CW field ergonomics

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

Ergonomics of Operating CW in the Field

by Dale (N3HXZ)

About a year ago I started getting active in Parks On The Air (POTA) and Summits On The Air (SOTA). I had always been an avid hiker and backpacker, and though I am getting up there in years (recently retired!) these amateur radio opportunities were just the medicine I needed to rekindle my passion for the outdoors and amateur radio.

Thanks to Thomas (K4SWL) and his blog post and videos I was able to quickly come up to speed on the basics and get out into the field for CW activations.  I quickly discovered that operating CW in the field is quite different from operating at home. The creature comforts of a good chair, a level and spacious operating table, and isolation from the weather makes for a great experience in the shack, but is not available in the field, especially if you are backpacking to your destination. My early activations were sitting on a rock, or the ground, and using only a clip board to mount my rig (Elecraft KX2), locate my CW paddle, and place a notepad to record QSO’s.

While simple, this operating setup poses problems. Attaining and maintaining a flat workspace is tough in the field in order to keep things from shifting or falling off the clipboard, especially if you are not firmly seated. There is not enough space to set your wrist in order to steady your CW operating, and the notebook pages can flap in the wind, or the wind can blow your logbook clear off the table while operating. I realized I needed to upgrade my mobile station! Continue reading Dale’s solution for enhanced CW field ergonomics →

A little off-grid radio and offline camping!

16 Comments

If you were hunting POTA contacts last week, you might have seen my callsign pop up in the spots quite a few times at New River State Park (K-2748).

Morning reading along with a proper brew in my C.R.A.Q. coffee mug!

Our family decided to take a little break from everything–including the internet–and simply enjoy the great outdoors and a little camping in our small travel trailer (caravan).

Our ferocious guard dog protecting the camp site from hostile invaders. Note that she’s actually awake and alert. A rarity indeed!

It was amazing fun.

In terms of radios, I limited myself to two. While we had room for more, I decided in advance I wanted to spend some proper bonding time with my Yaesu FT-817ND.

I’m so glad I did.

I also brought the Elecraft KX2 but primarily planned to use it when operating off-site. This way, I could keep the FT-817ND system hooked up and ready for action at our camp site.

In fact, the KX2 remained in my SOTA pack for the duration of the trip as a grab-and-go. I had an absolute blast with it activating the summit of Mount Jefferson.

Solar power

This camping trip gave me an excuse to use a station accessory I purchased last year: my Buddipole Powermini 2.

The Powermini 2 is a very compact and capable charge controller with an input for solar panels, a battery, two DC outputs, and even a USB power output. A genius little device.

I’ve been asked a number of times why I don’t do solar charging in the field during my activations. There are a few reasons, actually:

  • First of all, my activations tend to be short in duration–perhaps 45 to 75 minutes. I could easily operate for a few hours on one battery charge with most of my QRP radios. In other words, I rarely need to recharge in the field.
  • Often, my field activation sites are shaded by choice. Since I like to hang wires in trees, those same trees would block sunlight from ever hitting my panels.
  • Finally, unless I’m testing a new radio, I tend to take the least amount of accessories necessary to complete the activation. This is especially the case with SOTA activations. Since I’m unlikely to use solar panels, I leave them in the car or at the QTH. I do, however, keep them packed and at-the-ready should the need arise.

I paired the Powermini 2 with PowerFilm Solar folding panels I purchased many moons ago at Hamvention (I’m guessing in 2012 or so–?). These were blemished units and I snagged them for a brilliant price. Looking back, I wish I would have purchased a few more.

They’re only 5 watts each, but I run them in parallel to feed the charge controller with the equivalent of 10 watts.

QRP gear is so efficient, these modest panels actually do a respectable job keeping the battery topped off. At New River State Park it helped that our picnic table was in full sunlight most of the day.

Sure, we had shore power at the site, but where’s the fun in that?

QRM

During the week, the site had low levels of RFI/QRM. That all changed during the weekend when new campers moved in along with their leaky switching power supplies and noisy inverters.

On Saturday, I found it too frustrating to try making contacts from the campsite–the noise floor was a steady S7 with peaks around S9 simply washing over all but the strongest signals. I regretted not packing my Chameleon loop antenna.

Instead of fighting the QRM, I abandoned it. I drove to a large isolated picnic shelter at New River and set up the KX2 and CHA MPAS Lite antenna.

The site was noise-free and I had amazing fun.

Videos

I made quite a few activation videos, so I’ll eventually post them with abbreviated field reports.

Frankly, I am still catching up from having been offline so long.

Thank you

Massive thanks to my good friend Eric (WD8RIF) who took care of QRPer.com while I was gone. He’s been moderating comments and making sure scheduled posts published properly. In fact, my friend Robert Gulley (K4PKM) was holding down the fort over on the SWLing Post too. I’m so thankful to both of them.

Also, many thanks to all of the hunters who worked me on multiple bands and in multiple modes. A special shot out to NE4TN who was a life saver and spotted me on several occasions when the connection between the POTA site and Reverse Beacon Network were down. Many thanks, OM!

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 certainly not a requirement as my content will always be free, I really appreciate the support. Your support actually helps to make radio fun like this possible.

Here’s wishing everyone an amazing weekend!

Cheers & 72,

Thomas (K4SWL)

Speaker Wire SOTA & POTA: Another rendezvous with Rendezvous Mountain!

13 Comments

I get a little thrill out of checking out new parks and summits.

When going to a new-to-me site, I typically do quite a bit of research in advance. With parks, I look up directions to the entrance, hiking trails, park boundaries, and try to sort out the best potential activation sites on a map. With a summit, it can be much more complicated, but reading previous activator notes really saves a lot of headache. That’s especially the case here in the States where many summits are on private/gated land and/or could require bushwhacking off trail with no mobile phone service.

Then again, returning to a site I’ve been to before is also quite nice. I know what to expect and that often opens up the door to more confidence with time planning, antenna choices, and what to pack in terms of gear.

 

On Friday, March 25, 2022, I re-visited a site I hadn’t been to in nearly a year: Rendezvous Mountain Educational State Forest.

 

What’s great about Rendezvous is that it’s both a POTA and SOTA site.

On top of that (no pun intended) the activation zone of SOTA summit 2543 (W4C/EM-082) is on a road where Rendezvous Mountain Educational State Forest (K-4859), and Rendezvous Mountain State Game Land (K-6941) overlap. One activation yields two parks and one summit!

Last year, it took a bit of research to make this discovery. I studied both the park and game land maps, then compared those with a Cal Topo map. If interested, check out that field report here.

Rendezvous Mountain

I arrived on site around 12:45 local. The park was void of visitors–I almost felt like I’d arrived on a day when the gates should have been closed.

As I grabbed my SOTA backpack out of the back of the car, a ranger pulled up in his truck and  asked if I was planning to hike. I told him about my plans and asked if it was okay that I hike the forest service road to the summit. He said, “Sure. But when you reach the prison crew doing brush cutting on the road, make sure one of the guards sees you before you attempt to pass them.”

Okay then.

I thanked him and double checked that it was actually not a problem to hike the road and he said, “Go for it!” Continue reading Speaker Wire SOTA & POTA: Another rendezvous with Rendezvous Mountain! →

The Elecraft KX2 version of Scott’s chest plate/manpack

5 Comments

Many thanks to Scott (KA9P) who writes:

As a follow-up to my previous post: this chest pack is still a bit of a work in progress but has been tested and works as is. I didn’t want the non-IC-705 owners to feel left out 🙂

The Condor MCR-3 chest plate can be used with a Condor T & T pouch (30 bucks) for most QRP rigs with a KX format.

The Condor T & T pouch is a frequently reviewed favorite of hikers and hunters – YouTube videos abound. The key feature is the way the pouch opens from a chest plate, or just straps, to form a tray. I expect you could modify other clamshell pouches of other sizes with an adjustable cord to do the same thing. I haven’t seen other pouches built to do this, yet.

The “tray” section contains a number of MOLLE loops as well as some loop material. This makes it easy to fashion your own radio attachment system. I have been using some hook material fastened to the back of KX2 for now, but am working on something that locks in, rather than tempt fate.

Guest Post: Fraser Activates Ben Newe Despite the Winter Weather

4 Comments

Last week, while browsing Twitter, I scrolled past a short note and photos from Fraser (MM0EFI) describing his recent activation of Ben Newes in NE Scotland. I’m not sure if it was the snow, the KX2, or his vintage Land Rover (or all of these) but I wanted to know more about this activation.

Fraser kindly agreed to share the following field report for us here on QRPer.com: 

Ben Newe SOTA Mini-adventure

by Fraser Wenseth (MM0EFI)

Introduction

I’ve lived on the eastern edge of the Cairngorms National Park in north east Scotland for around six years. I’ve always climbed the hills, winter and summer, enjoyed rock & ice but now just love being outdoors. I’ve held an amateur radio licence for 18 years but have to admit that until I discovered Summits on the Air (SOTA), my licence was under utilised!

SOTA has allowed me to discover local hills that I had previously driven by on countless occasions on my way to bigger adventures, or so I thought, because it’s possible to have amazing adventure on smaller hills just by picking the time of day, season, or even choice of radio gear. Sometimes I’ll just carry VHF gear, which is always a challenge in a rural area! Of course I still love a big day out in the mountains, but todays story concerns a little hill just 7 miles from my home in Royal Deeside.

It’s called Ben Newe and its’ SOTA reference is GM/ES-053. It stands 565m or 1853’ above Strathdon in Aberdeenshire. I’d planned on climbing it after work. Generally I work a really early shift one day a week and the motivation for getting out of bed at 0340 is knowing that I’ll generally be on a summit around 12 hours later.

I left for work at 0400 (British Summer Time, UTC+1) and that’s when the snow started falling. It actually didn’t stop until 1900 that evening. We’d had an unusual winter, with little snow. Here we were in April and it had snowed for over 12 hours! I really wanted to get out for a SOTA activation and the snow was only going to enhance my adventure. I spent some time (probably too much time) thinking of suitable peaks to climb whilst at work that day. Ben Newe fitted the bill perfectly.

CW saves Leo’s POTA activation during a low battery warning!

5 Comments

Many thanks to Leo (DL2COM) who writes:

Thomas,

Today was crazy: when I woke up I thought it would be a good idea to attempt a first activation of DA-0171 in central Berlin after dropping off the kids at day care. So I grabbed my KX2 bag and jumped on my bike.

Shortly later I arrived at the park and pulled up my 40-10m EFHW and started calling CQ on SSB 40m.

It took me about 30 mins to realize that the KX2 was regulating the power down to 5W since both the internal and the external 4Ah battery I took with me were nearly dead.

I had one QSO with a German station and felt I wasn’t really heard anywhere. Then my KX2 started showing “low batt”.

It’s funny because attempting an activation isn’t really what one would call a very important thing, but I do develop quite an ambition if I have decided to get it done. So my only chance was using CW even though I am all but ready for that.

Having read your article about auto-spotting and watched many of your videos including POTA QSO style I didn’t think long and started calling CQ POTA on 20m.

OMG what followed was just amazing!

Fortunately I didn’t run into a classic pileup which would have been super overwhelming for me, but instead about every 2 minutes someone would reply to my call and in a very patient fashion – including one P2P QSO with an operator from Italy.

So all in all I completed 13 QSOs on a “low batt” warning of my KX2.

CW literally saved by butt and I am a very happy person. Without your work for the ham radio community this would not have been possible. So many thanks again.

On a different note: Last weekend (kit building seminar with the club) I had my first DX QSO. It was K3LU who picked up my call from my KX2 and a random wire 9:1 Unun antenna (L-Shape on a mast) with 28 and 17ft legs. I had to sit down and open a beer not able to do anything for about an hour but smile. Such a motivating event and I am happy he was such a great operator instantly QRSing with me and repeating his call. I am in touch with him and looking forward to receive his QSL card which will probably go in a frame.

I also finished the TR-35 and must say I am super impressed. It runs very quietly and the reduced concept is something I really appreciate. When will you take it into the field?

All the best & 73s de Leo (DL2COM)

Oh wow, Leo! I love this–thank you so much for taking the time to share your experience.

First of all, thank you for the kind comments–I’m honored to have even played a minor role in your CW activation. In truth, this is all chalked up to your determination and bravery! I’m guessing what you discovered is what I discovered during my first CW activation: not only is it not as bad as I had imagined, but it was actually fun and got the adrenaline pumping! 🙂 

I’m now happy to know that when I hit the Low Battery warning on my KX2, I still have some time left! In truth, the KX2 is so efficient, I’ve made six individual CW 5 watt activations on one charge of the internal battery without even hitting the low battery warning. 

Again, this story just makes my day. CW is such a fabulous, efficient, and magical mode! Good on you for diving in, OM!

I also think it’s brilliant that you worked Ulis (K3LU). You couldn’t have worked a better op for your first CW contact–he’s the real deal and a wonderful fellow. Not only that, but he has some amazing QSL cards!

And the TR-35? I couldn’t agree with you more. I did an activation with the TR-35 last Friday so a video and field report is forthcoming!

Thank you again, Leo! I hope others share their experience hitting CW for the first time (hint, hint!).

New Beta Elecraft KX2 and KX3 Firmware

4 Comments

Many thanks to Tony (AE0KW) and Eric (WD8RIF) who note that Elecraft has released new a Beta firmware for the KX3 and KX3 that extends the time before the radio drops to 5W in CW mode:

  • The KX2 release extends CW operating time at 10 W by allowing the supply or battery voltage to go as long as 9.0 V before dropping to 5 W.
  • The KX3 release has the same CW power improvement, as well as a fix to the TX inhibit function of the ACC2 jack.

A quick roadside activation with the Elecraft KX2 and CHA MPAS Lite

5 Comments

There are days when I leave the QTH and have no idea if I have enough time to fit in a park or summit activation. Because of this, I always keep a radio field kit in the car.

On Monday, January 31, 2022 I had an appointment-packed day ahead of me, but I was hopeful I might be able to squeeze in a quick activation of some sort.

Specifically, I had a new-to-me super easy, drive-up SOTA site in mind: Peach Knob (W4C/CM-097). In fact, it’s a bit odd that I hadn’t activated this site before. It must be the most accessible summit (to me) in the area.

After a 2:00 appointment in downtown Asheville, I drove 15 minutes to the summit of Peach Knob where I discovered 1.) there was almost no space to park and 2.) what little space there was was taken up with crews working on a cluster of communications towers. In situations like this, the last thing I want to do is get in the way; that sort of activator persistence could lead to “no trespassing” signs in the future.

The site also reminded me that what I love about SOTA is the hike to the summit. Sites like this one are wedged between private property and city property–I just feel like I’m in the way, arousing neighborhood suspicions, and just doing the activation for the points. I’m not a points guy (though I’ll do a happy dance when I accumulate 1000 for ‘Mountain Goat’ status sometime within a decade at this rate).

Moving forward, I think I’ll skip drive up sites like this one; at least for HF activations.

At this point, I pretty much abandoned the idea of a field activation as I’d taken up the wee bit of free time in my schedule just checking out Peach Knob.

Next, I popped by Vlado’s (N3CZ) QTH to drop off some parts so he could finish the repair of my Elecraft KX1.  While chatting with him, I received a message from our grocery store noting that our 4:00 curbside pickup would be delayed. This opened up a one hour window where I could perform an activation! Woo hoo! Continue reading A quick roadside activation with the Elecraft KX2 and CHA MPAS Lite →

POTA RaDAR Run Activation #2: Pisgah National Forest & Pisgah Game Land

8 Comments

As mentioned in my last field report, on January 26, 2022, I decided to fit in multiple park activations in one day as a RaDAR (Rapid Deployment Amateur Radio) run. My hope was to activate four or five sites between 14:00 – 21:30 UTC.

The first activation at Lake James State Park went so well, it started me out a little ahead of schedule.

After packing up my gear at Lake James, I began a 40 minute drive to the second site–Dogback Mountain–where I hoped to do a POTA two-fer along with a Summits On The Air activation.

The drive was beautiful. Only twenty minutes into the trip, I came to the forest service road that lead to Dogback Mountain. For a six mile drive, Google Maps was telling me it would take about 20 minutes, so I knew the dirt road would require slow driving.

The road was actually in pretty good shape, but there are rocky and rough spots that pretty much require good vehicle ground clearance. My Subaru had no issues at all–in fact, I love driving on back roads like this!

Three or four miles into the forest service road I reached an impasse.

While there hadn’t been snow in the area for at least a week, the north slope portions of the road were quite icy. The thaw and night time freezing pretty much meant that there was no snow to navigate–only ice, and I’m not a big fan of ice.

I already passed through two sections of ice where I could still manage a little traction on the side of the road (at least half the car had traction). At one point, though, I saw a large section of icy road ahead, so I parked the car to investigate what it looked like over the crest of the hill.

It was so icy, I struggled to find a spot to walk on to peek over the hill and almost slipped once. That hill was pretty steep and I could see no spots for the car to get traction. Remembering what my wife said that morning (“Don’t do anything crazy, okay?“) and knowing that the worst thing for my RaDAR run would be getting stuck in a spot recovery vehicles might struggle with, I chose the option of forgoing the summit activation.

Frankly, if the summit activation was the only thing on the schedule that day, I would have likely parked, then hiked 3 miles to the summit along the forest service road. But my RaDAR run left no time for this.

Fortunately, where I parked was firmly in the two-fer zone of Pisgah National Forest and Pisgah Game Land!

Pisgah National Forest (K-4510) and Pisgah Game Land (K-6937)

I parked the car on one of the many roadside camping areas right there on the ridge line. It was an ideal spot for a field activation: good altitude, no obstructions, and lots of trees. Continue reading POTA RaDAR Run Activation #2: Pisgah National Forest & Pisgah Game Land →
