Pairing the Elecraft KX2 and AX1 with a little QRP Coffee for some proper portable POTA fun!

Driving home on Thursday, December 8, 2022, I popped by Food Matters in Morganton, NC and grabbed one of their amazing curried chicken salad wraps.

I sat in the car and listened to a podcast as I ate a late-ish lunch. I looked at my watch and sorted out what time I needed to be back at my home in the mountains. After a little mental math, I realized I had about 90 minutes to fit in a little radio fun.

Where to go on a rainy day?

Tuttle Educational State Forest (K-4861)

Since it was a Thursday and I knew Tuttle would be open, it was really a no-brainer. Tuttle is only an 8 minute drive from the parking lot at Food Matters, so I made my way to Playmore Beach Road!

En route, I made a mental inventory of what radios and antennas I had packed in the car. I knew I had my KX2 and although its internal battery had already powered me through three or four activations already, I knew there’d be enough charge for one or two more.

Also, since it was raining, I thought it would be the perfect day to set up under Tuttle’s excellent picnic shelter.

As for an antenna, I remembered putting the AX1 in my antenna box, so why not pair the two and operate in the dry?

Coffee Time

Funny, but after I started recording the activation video (below), I convinced myself that I needed to make some coffee. I pulled out my field coffee kit and set it up for a quick brew.

The park had completely shut off all water fountains and closed the rest room area, so there was no place to get fresh water. Fortunately, I had *just* enough water left in my water bottle after lunch. Almost the perfect amount for a cup of coffee but no more.

This wasn’t a planned cuppa’ so I used one of my last Starbucks Via coffee packs. Had I planned this in advance, I would have ground some beans at home and made a pour-over coffee.

That’s okay, though. The Starbucks packs are better than no coffee at all.

Field Coffee Kit

If you’re curious about the contents of my field coffee kit, here’s the list:

Activating Plaines d’Abraham in Old Québec with the KX2 and AX1 combo

When we spend the summer in the province of Québec, we always set aside at least one day to hang out in Old Québec. This portion of the city of Québec is simply stunning: it’s a UNESCO World Heritage site and the birthplace of French North America.

No other place in North America reminds me more of the years we lived in Europe than Old Québec.

We’ve been to Old Québec a countless number of times over the past two decades; we enjoy checking out the architecture, the window boxes full of flowers, and the numerous museums.

Old Québec is, of course, quite touristy–especially if you visit on a weekend. It can be incredibly busy and also challenging to find parking especially if, like us, you have a cargo box on top of your car (many parking decks have strict height restrictions).

On Tuesday, July 26, 2022, we decided to make a trip into Old Québec to visit some of our favorite book shops, small businesses, enjoy a lunch together, and soak in some of the amazing weather.

My wife encouraged me to find a nice POTA site and–wow–is one spoiled for choice! There are no fewer than 10 POTA parks in/around Old Québec. Check out the POTA map–each yellow dot is a park:

I know Québec City well enough to know that some of these parks wouldn’t be terribly easy to activate since they’re historic buildings and sites–I think it could be done, but you might need to seek permission in advance. I think it would be incredibly fun to set up a multi-park rove on foot; in fact, I’ve put that on my bucket list for a future trip!

The park I was eager to activate is the largest in central Québec City: The Plains of Abraham. It’s a beautiful and open urban park that overlooks the the St-Lawrence river. It’s Québec City’s version of Central Park.

Plaines d’Abraham (VE-1019)

I was very fortunate: after we dodged a little road construction, I found parallel parking on Ave Winfred-Laurier next to the Parc Jeanne d’Arc.

Poor Propagation: Can the Elecraft AX1 handle band conditions during this urban POTA activation?

Typically, when I do field activations while on vacation, I squeeze them in and around our family activities and travels. This is quite easy to do because our family enjoys a good hike and we love our parks.

On July 4, 2022 (Independence Day in the US!) my wife and daughters had their own activities planned for the day which opened up nearly a full day–at least a good 5-6 hour window–for me to do park activations solo.

Château Frontenac in Old Québec

I had numerous park choices in/around Québec City–an area rich with POTA sites.

I thought that I could either spend the day hitting one park further afield or hit multiple parks clustered together.

I chose the latter, so I started researching the POTA Map for Québec City.

In truth, pretty much any of the parks in Québec City could have been pieced together for a multiple park run. In fact, there are a number cluster in the city center and in Old Québec, but I was keen to explore a little cluster of parks I noted in the Saint-Foy area west of Québec City:

The map below shows just how close these four parks are to each other. Very doable!

These parks were so close to each other, I considered parking in the middle and simply walking to each site, but after reviewing the distance between the potential activation sites at each parks more carefully, I realized I wouldn’t have the time to activate all four parks if I walked it.

It was this activation that reminded me how brilliant it would be to own a folding bike like by buddy Jim (N4JAW) uses on each of his nearly daily POTA activations. With a bicycle, I think I could have actually activated these more quickly than I could with a car because there’d be no need to find a parking spaces at each site.

The Plan

I decided I’d try to hit my four parks in this order:

The only park I’d visited in advance was Parc Cartier-Roberval so I knew I’d need a little time to find activation sites, etc. at the other three. If the activations took longer than expected to validate with 10 stations logged, I might have to skip the final park.

Interestingly, three of these four parks were ATNOs (All-Time New Ones) thus had never been activated for POTA. Continue reading Poor Propagation: Can the Elecraft AX1 handle band conditions during this urban POTA activation?

Fitting in some QRP SOTA & POTA on Mount Jefferson!

Looking back at last year (2021), if I had to pick out one of the easiest SOTA activations I made, Mount Jefferson would be near the top of the list. It’s a very accessible summit although not technically a “drive-up” summit because you will need to walk a short distance up a service road to the activation zone (AZ).

Mount Jefferson (W4C/EM-021) is located on and protected by the Mount Jefferson State Natural Area (K-3846), so when you activate Mount Jefferson for Summits On The Air, you can also claim the activation for Parks On The Air and World-Wide Flora and Fauna as long as you work at least 10 contacts.

What I love about POTA and SOTA “2-fer” sites like this is that you can set things up to be spotted in both systems (and often the WWFF system, too!) which increases your audience of hunters and chasers, thus increasing your odds of achieving a valid activation in all programs. It’s especially desirable if you’re a CW op and know you may potentially be in a spot with no mobile phone service for self-spotting; if, for some reason, RBN auto-spotting functionality is down with one program, the other serves as a backup.

Mount Jefferson is at least a two hour drive from my QTH, but it was easy pickings on April 29, 2022 because it happened to be within spitting distance of New River State Park where I was camping with my family.

Mount Jefferson (W4C/EM-021)

The drive to Mount Jefferson took all of 20 minutes which was a good thing because our family had other activities in store that day including some extended hikes!

Hazel (above) was so excited to to check out the sights and smells at this new-to-her park! Continue reading Fitting in some QRP SOTA & POTA on Mount Jefferson!

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

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!

A little off-grid radio and offline camping!

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,

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

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.

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

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!). 

Field Activation Antenna Challenge #1: Military Fixture Homemade Multi-band Doublet!

I mentioned in a previous post that my personal “Activation Challenge” for 2022 was “to build a new antenna each month and deploy it at least once that month during a field activation.”

On Thursday, January 27, 2022 I took my first antenna–the military fixture doublet–to Lake Norman State Park for a Parks On The Air activation!

For more information about this doublet and how it was constructed, check out this post.

Lake Norman State Park (K-2740)

I picked Lake Norman knowing that it had numerous spots to set up a doublet.

Unlike an end-fed wire antenna, doublets need a little more clear space to deploy both legs; the idea is to avoid as many low tree branches and other obstacles as possible.

Many (if not most) of the operators I know who regularly deploy field doublets actually use a telescoping mast for the center support to make the whole process easier.  I didn’t take either of my fiberglass masts on this outing because, frankly, the winding fixture on this doublet acts as the center insulator, and is “heavy” compared to most of my field antennas.

Summits On The Air: Pairing the Elecraft KX2 and Chameleon CHA MPAS Lite on Bearwallow Mountain!

So far this winter has been a challenge in terms of activating summits. For me, at least.

Between my busy schedule, family life, and the weather, it’s been difficult to make the stars align. Activating a summit, in general, requires much more time than activating a park. At least, where I live.

Summits tend to be much less accessible and time-consuming than, say, a state or national park. Besides getting to the summit trailhead and hiking it, there can be quite a bit more research in advance including reading previous activator notes and mapping out the true summit location.

SOTA (Summits On The Air) activators (depending on their location) often have extra incentive to do activations during the winter because many of us can accumulate “bonus points” for summits above a certain height during the winter months.

As I’ve mentioned before, I’m not a numbers guy and honestly couldn’t tell you, for example, how many parks I’ve activated this year. But it would be awfully fun to eventually achieve “Mountain Goat” status in the SOTA program. It requires 1000 (!!!) points. Many of the summits where I live range from 1 to 10 points each. Each summit can only count once per year, so if I activate Mount Mitchell (our highest summit) the 10 points only count once in 2022 toward Mountain Goat status. The program is designed to encourage activators to activate a wide variety of unique summits each year. It’s a brilliant motivator.

I will be happy if I achieve Mountain Goat status in 5 years. I simply don’t have the free time to hit summits as often as I’d like. It is a really cool goal though.

Now where was I–? Continue reading Summits On The Air: Pairing the Elecraft KX2 and Chameleon CHA MPAS Lite on Bearwallow Mountain!
