POTA at Lake Norman: Beautiful day for a TR-45L trailside activation (and hunting VE6LK)!

I’m getting used to having an electric vehicle for my weekly travels including POTA and SOTA excursions.

My Volvo C40 has a published range of about 226 miles on a 90% charge, but I find that I actually get more than that. I almost never need to recharge from a public charger–I just plug it in at home.

At least once a week, I visit my parents in Hickory, NC and that round trip (including errand running in town) logs a good +/- 200 miles. By the time I return to the QTH, I typically have a comfortable 20% charge left on the battery.

Many of the parks I activate in that travel corridor are 20-30 minute detours off of Interstate 40 (for example: Lake James SP, South Mountains SP, Tuttle Educational SF). They have no negative impact on my ability to make it back to the QTH with battery capacity to spare.

Parks, however, that are still close to Hickory, but in the opposite direction of home, may necessitate a quick charge at one of the many public charging stations along the road. Not a big deal, but it’s kind of fun when I can do a full trip on one charge.

Flag at half staff in memory of September 11, 2021

On Monday, September 11, 2023, I had a full afternoon open and really wanted to fit in a proper hike. One of my favorite easy six mile loop trails–the Lakeshore Trail– is at Lake Norman State Park.

Lake Norman, however, is in the opposite direction of the QTH and is about an 80 minute round trip. I fit in errands along the way, but going there means I’ll need a bit of a charge to get back home the following day.

After a little research, though, I discovered that Lake Norman (much like Lake James) has free EV charging at their visitor’s center! Woo hoo!

Lake Norman State Park (K-2740)

I arrived at the park in the early afternoon and–whew!–both of the EV charging stations were free. In fact, the visitors’ center parking lot was almost empty–I would have expected a few more cars. I found that curious.

I plugged in my car, put on my hiking boots, grabbed my hiking sticks, then made my way to the spur trail that connects the visitors’ center parking lot to the Lakeshore loop.

Only, when I reached the trailhead, there was a notice stating that all of the trails were temporarily closed. Wait…what?

This may explain the lack of visitors.

I was bummed to say the least. My backup plan would be to hike the road at Lake Norman, but that’s not nearly as fun as a proper trail.

I then walked to the visitors’ center and asked the staff inside about the trail closures. They pointed out that there was one small loop trail–next to the visitors’ center–that was still open.

I was pleased to hear that and decided that instead of hiking one long loop, I could simply hike the same small loop several times.

I thanked them then gave them a donation (which I was going to do anyway) especially since I was getting free EV charge!

I walked out the side entrance of the building and onto the Alder Trail.It was a very nice little loop trail and long enough that I didn’t feel like I was walking in circles. Continue reading POTA at Lake Norman: Beautiful day for a TR-45L trailside activation (and hunting VE6LK)!

NL5E SOTA/POTA Backpacking Kit

Description

Hello! NL5E here.

I’m one of the rare SOTA activators in Alaska (I also use this same kit for POTA). Anyone that has looked at a map of this state will know that we have some interesting difficult topography. Many of our summit hikes start out near sea level, but are 3000-6000 vertical feet of climbing to get to the summit. So I built my kit with compactness, versatility, and weight in mind. Everything weighs approximately 2lbs (not including the battery, I don’t always take it).

My primary operating modes are CW, FT8, and SSB.

To facilitate those modes I tried to keep everything as small as possible while still being usable. For example, I debated using N6ARA’s tiny paddle, but I found I made too many sending errors. The N0SA paddle is a perfect medium between portability and sending ability. For FT8 the FT8CN app has been a good alternative to carrying a Raspberry Pi or small laptop and the well loved Digirig is probably the best audio/cat interface on the market today. I don’t do a lot of SSB (especially at QRP levels), but the K6ARK mini microphone is a wonderful improvement over Elecraft’s comically massive microphone for the KX2. I added headphones so I don’t disturb anyone on popular summits and so I can hear CW a bit better.

My antennas of choice tend to be random wires and End Fed Halfwaves.

With the KX2 I chose to use K6ARK’s 20w antenna kits and built both a 9:1 and 49:1 version. I usually carry the 9:1 just to have the band flexibility as it will work from 40m-10m. If the ground is wet enough I’ve had it tune up to 80m.

For the 49:1 I chose 20m because bands lower than that have mediocre performance from the latitude. Because of how short both these antennas are, they pair very well with the SOTAbeams Carbon 6 mast. From a summit a 19’ mast is usually tall enough to work most of the US and lots of Asia from here. The only modification I made is gluing the top 2 sections together for durability. To attach the antenna wire I use a small Niteize carabiner and a prussik loop.

I also wanted to ensure that I could power many different devices while out hiking. I settled on an Anker battery because it is easy to power phones and the radio without having to bring a bunch of different adapters like I would with a dedicated 12V battery.

I know someone will mention protection and the bag I chose. Yep, a silnylon stuff sack offers zero protection from bumps and impacts. I firmly believe that hams “over baby” their equipment and think that their radios will hilariously explode if sneezed on wrong. I settled on the Gems Products cover and rails as a good solution to keep the radio from getting destroyed in a backpack. So far so good. I added the dry bag to my list for rainy days.

I didn’t include one in the images, but I also usually have an HT with me, but most summits don’t have good line of sight to our population centers. I usually run a Yaesu VX-6R with Diamond RH77CA or MFJ Longranger. I will usually run 2m FM when I am close to Anchorage or Palmer. I also didn’t include my logging solution, but that is usually HAMRS on my iPhone or a Rite in the Rain book and pencil. I find CW is easier to log on paper for some reason.

Thanks for looking and perhaps I’ll hear some of you on the air.

My QRP Portable Set up

by Ed (W4EMB)

Radio: I have one priority rig I use 99% of my time. It is the TR45L Penntek. I have both versions. The fullsize one with built-in tuner and battery, I also have the “Skinny” version. The skinny does not have the tuner nor battery. My second Rig is the Yaesu 817 with the Windcamp Battery upgrade. I also have a 40m only QSX and the 5 band TruSdx.

Penntek TR45L Skinny with external batter and external tuner.

Antenna:  I use the Chelegance MC-750 most of the time, but also use a Homebrew EFHW with 49:1 balun and 67’ of wire.

I have the QRP guys Tri-Band vertical kit, and two pieces of 16ga Speaker wire cut to 33’ that I carry as well. To support the EFHW and Speaker wire antenna, I use the SOTABEAMS 10m (32 ft) “Travel Mast”.

For the QRP Guys Tri-band vertical, I use the SOTABEAMS Carbon-6 ultra light 6m (19.6 ft) mast. To support the 32’ mast I usually just lean it into the trees and slope my EFHW up from the feed point.

For the speaker wire antenna, I run the “red wire” straight up the mast while it is strapped to the picnic table. The “black wire” is simply thrown out across the ground. I might even elevate the black wire with sticks.

My carbon-6 fits right into a piece of 1 ¼ inch PVC pipe I have clamped to my brush guard on my van. Or, I use a Tiki-Torch stake to hold my carbon-6 in open ground.

carbon-6 with Tiki-Torch stake supporting and using the Tri-band Vertical.
carbon-6 inside of PVC pipe with the QRP Guys Tri-band vertical.

I find for me, that my QRP Guys antenna works great on 20m without a tuner. But when I try to use it on 30m or 40m, I require a tuner. For this reason, I lean on my MC-750 to be the main antenna.

I have modified my MC-750 slightly. I made my own set of radials to match the factory ones. I chose to make them out of silicone wire. I find it to be more flexible and does not kink or tangle as easy as the standard factory radials. I used 3mm banana plugs and 24ga yellow wire. I also crimped small ring connectors onto the ends of the radials. I did NOT strip the insulation and place them on the wire. I simply crimped them on the silicone. I use them to stake down the wire. I use four nails as “stakes” to pin the wire down. I find I only stake the radials out when I am on un-even ground.

The second modification, I made a set of “double” radials out of 26ga green silicone wire. Colors do not matter. It is what I had. I spread them evenly around the base of the MC-750.

MC-750 with “double radials” and RG316 for coax.

My key is a Czech military straight key from the 1950s. It was new old stock when I bought it. I also carry a small mini set of paddles. For the TR45L radio, I can not play my recoded CQ or 73 with out a paddle. The “play” button is dit or dah trough the paddle jack.

For coax, I use RG316 and the appropriate adapter for the MC-750.

I have two pencils from Kuru Toga. One pencil is .5mm the other is .7mm. I make my own POTA log sheets and I paper log, and then type them later. I am a not talented enough yet to play with a tablet or PC while operating. I have only done CW for the last 12 months.

On my table: I have a really thin yoga mat. I find the concrete picnic tables a bit rough on my equipment. The yoga mat can get a bit sticky when it is warm, so I drape a small hand towel over the edge where my arms lay. I also have a Write in the Rain tablet in full size paper. I have been out early in the mornings in this summer and humidity and steamy fog makes normal paper hard to write on. The .7mm pencil matches up well with the Write in the Rain paper.

I have found CW and POTA have re-energized my ham radio hobby and resurrected it from a dusty shack, to a fun out door activity.

My first challenge was how to get from the car to the table in one trip. Downsize to the necessities. Next was figuring out the antenna and radio combo that could work in different conditions. By conditions I mean space.

Location, location….. I had a dog run between me and my antenna. It pulled my radio right off the table and tumble behind the dog. So now I choose my locations like Bill Hickock… always face the door. Hihi. Food for thought.

Thank you to Thomas for inspiring me to get out there and do it. His you tube videos were great copy practice to give me the confidence to get out there. Finally, my Elmer. John, KM6NN. Without him I would have never started my CW journey. He is a true Elmer in every definition of the word. I am proud to know him and lucky he is in my life. Thank you John.

Out Of My Element: An Urban POTA activation at the Thomas Wolfe Memorial

It’s funny, but until September 7, 2023, I had never activated one of the closest POTA sites to my home: the Thomas Wolfe Memorial (K-6853).

I remember back in 2020 when I really kicked my POTA activations into high gear, I made a spreadsheet of all of the POTA sites within a 2 hour drive of the QTH and started activating them one by one.

At the time, almost 50-60%, or possibly more, had never been activated. Keep in mind that in early 2020, POTA had a wee fraction of the activity it has today.

It was a lot of fun especially considering those were the early days of the pandemic and it was just nice to get out and about. Any excuse, right?

The Thomas Wolfe Memorial is on North Market Street in Asheville, NC.

One of the parks on my list was the Thomas Wolfe Memorial but being a small historic site in an urban setting, they were closed for quite some time during the pandemic. There was nothing to stop me from walking on the site–or pulling up in their parking lot–and doing an activation while they were closed, but I just didn’t feel like it should be fair game when closed.

Then restrictions loosened up and, frankly, I just sort of forgot about it.

I tend to activate parks in rural areas and I am prone to overlook urban sites (although quite a few of my activations in Canada last year were urban).

Thomas Wolfe Memorial (K-6853)

On Thursday, September 7, 2023, I dropped off my daughters at school then made my way to a doctor’s appointment. I arrived at the office, gave them my name at the front desk, and then they reminded me that we had re-scheduled this particular appointment for later in the month.

Doh! I forgot to make the change in my calendar.

All of the sudden, I had a bit more free time!

Of course, I always fill free time with POTA activations, and I already had radio gear in the car, so it was only a matter of deciding where to go.

I called the Vance Historic Birthplace (about a 25 minute drive) to see if they were busy. Their director (who I know quite well at this point) told me that a large group was on the site, but would be gone by 1:30. That timing didn’t work for me, so I consulted the POTA map.

Since the POTA site used my coordinates to find the closest park, I was reminded that K-6853 was a mere 3 minute drive from the doctor’s office. I could have walked there.

I gave the site a call to ask for permission (again, I always do this for small historic sites) and they told me I’d be most welcome.

The site is on a small urban lot and consists of two buildings: the visitors’ center, and the Old Kentucky Home boarding house. Continue reading Out Of My Element: An Urban POTA activation at the Thomas Wolfe Memorial

Hi Tom,

I thought I would share the two go kits I have. I tend to customize my equipment and supplies before I go on a POTA or SOTA outing but I keep these for the rare occasion when I want to grab a radio real quick. [The first on is my] QRPlabs go kit:

The kit is for my QRP Labs QMX/20 meter QCX mini. It contains everything I need to operate 20 meters CW.

The case is a regular Lowepro case that I got with my KX2 when I purchased it from another ham. I did not realize it came with it so I accidentally ordered an extra from Elecraft which I now use with the KX2 kit [featured in a future Field Kit Gallery post].

The kit uses many components from K6ARK, including the 20 meter EFHW antenna and the retractable paddle.

The battery is a TalentCell from Amazon. I use it because it supplies 12v instead of 13.8v. One of the downsides of the QMX is that it cannot handle 13.8v, so I have to stick with 12.

I keep a cheap pair of earbuds with me just in case but I try to bring a nicer pair of headphones whenever possible.

Hopefully this information is useful to you and your readers!

[I]n my truck I carry a little field kit for impromptu POTA activations.

I also have an FT-891 to an ATAS-120 permanently installed in the truck, which is another possibility for impromptu activations, but that requires me sitting in the truck for the activation. Not my favorite way to activate …

The SW-3B truck kit consists of:

All in a large Bagsmart electronics travel organizer (the case is too large, but since I only carry it in the truck, it didn’t matter)

With the case hung over a headrest hook behind the driver’s seat.

What a great idea [to share field kits]. I’m really curious to see what others post.

A beautiful (and hot) day for a QRP SOTA activation on Bearwallow Mountain!

Tuesday, September 5, 2023, was a gorgeous day. A hot day, but a beautiful one!

I couldn’t pass up the opportunity to fit in a quick SOTA activation and the most accessible summit that day was Bearwallow Mountain.

Bearwallow Mountain (W4C/CM-068)

I was in South Asheville all day, so Bearwallow was only about a 25 minute detour.

Since it was a Tuesday in the latter part of the morning, there were few others parked at the trailhead. Had it been a Friday, Saturday, or Sunday? It can be difficult to find a parking spot. Indeed, the previous day (Labor Day) I’m sure it was packed!

I practically had the place to myself, though.

The hike up was most enjoyable although it was hot and humid, so sweaty I became.

That said–and I think I even say this in the activation video below–I really wished the hike was a bit longer. The Bearwallow trail is maybe a mile long.

I wanted a longer hike, but in truth, didn’t have the time for one anyway.

Bearwallow’s summit is a large pasture. It does offer up some spectacular long-range views.

Bearwallow is also home to a lot of comms towers including a number of local repeaters.

I found a nice, flat rock, set up my chair, and deployed my Chelegance MC-750 vertical. Continue reading A beautiful (and hot) day for a QRP SOTA activation on Bearwallow Mountain!

Business Travel & POTA: It’s as simple as One … Two … Three!

by Vince (VE6LK)

As always there are lots of links within the article. Click one! Click them all! Learn all the things! 🙂

The backstory

For those of us that work from home there are good and not-so-good things about it. One of the not-so-good things is that I’m not getting out somewhere every day like I used to, thus I embrace corporate travel as it represents a mini-escape from the day-to-day activities that would normally happen.  It also gives me an opportunity to operate in the field and away from the comfort of sites nearby my home.

In late September I was in the Edmonton Alberta area for work and, as always, I brought along a set of gear to play radio. Where I’d normally drive up and park my F-350 within the boundaries of the park and operate from the cab of the truck, this time I was in a rental vehicle so I had to be well-equipped for the unknowns. I also didn’t pre-plan my stops like I normally would, I just wanted to roll up and do my best to make it work.

These would all be CW activations at QRP power and are part of my 200 CW activation contacts per month personal goal to improve my CW skills. (Spoiler alert: I hit the goal while writing this article!) See below for my kit list that made this possible.

Not really pre-planning an activation is a stark contrast to how I normally roll as I usually pore over maps and satellite views on multiple websites to visualize where the park entrance is and where I’ll set myself and what I may encounter for surroundings when I get there. I know exactly where I’m going and just about down to the parking space. I build a set of kit up to support that/those activation/s.

With the lovely autumn weather we were experiencing in Alberta, my plan was to activate after work opportunistically around Edmonton – something I’d not yet done despite many trips to the area – and set up and operate right around 0000z. This time is after my workday, so a nice mental break from the day’s activities before kicking back for the evening. I think to my self that I’ll roll into a site nearest to where I was working arriving just before midnight UTC (1800h local) and get set up and start calling once the clock ticked over into a new day. From there I would then head to the hotel (or home) and grab a bite to eat and close my day off on a high note.

I’m in portable field radio kit mode…how about you? Care to share?


A portable field kit:  it’s a seasonal thing.

In the early fall and spring, I go over my QRP radios and give serious thought to how I’ll build compact field kits around them.

Why? I’m pretty sure it’s the pending change in weather that’s the catalyst.  The temptation to get back out there and make some contacts.

Then again, any excuse:  I absolutely love building field kits, and fortunately it never gets old.

The radios I’m considering at present are my MTR-3B (named Threepence) and KX1, now named Audrey. (Yep, I chose “Audrey”…thank you for all of the amazing suggestions!)

Both of these are ideal little radios for kitting out because they’re so compact and truly made to be taken to the field.

One of these two radios––and I haven’t decided which one yet––is going to live in my EDC bag.

The Tom Bihn Stowaway in black has been my EDC bag for many years. I’ll need to pay attention to the weight and bulk of this field kit, because I’ll be lugging it pretty much everywhere.

I’ve got some ideas and a couple of pouches in mind, so this will all start coming together soon.

But first…

Care to share your portable radio kit?

One of the things I enjoy doing when I’m putting together a new field kit is to check out what others have done.  It’s a great way to get some fresh ideas…and besides, it’s  just plain fun to compare notes.

If you would like to showcase your field radio kit on QRPer.com, please send a short write-up with photos detailing how/why you built your kit as you did, and list all of the components with links to the manufacturers.

We’ll not only publish your field kit article as a post, but also on this new Field Radio Kit Gallery page I created!

We only ask that you send your own original ideas––and not just a link to another website article or video––as we’d like this content to become part of the QRPer archive.

One Watt, Low-Profile QRP: A Labor Day POTA Activation at Lake James State Park

I realize that I’m fortunate, in many ways, that I perform POTA activations at times when parks are relatively quiet: weekdays, mostly, and during that 9-5 window when many are at work. On the flip side, I’m also activating when there are fewer hunters out there.

The upshot, for me, is that I rarely have any competition for picnic tables or activation spots at state and national parks. In general, as you’ll see in my activation videos, the park is quiet and sometimes I literally have the place to myself.

I actually take this for granted until I activate on a busy weekend or a holiday. Something like…

Labor Day!

While traveling back to the QTH on Monday, September 4, 2023, I decided to pop by Lake James State Park (K-2739) for a quick POTA activation.

Lake James State Park spans about 3,743 acres and is divided into two areas: the Catawba River Access and Paddy’s Creek Area.

Typically, I play radio at the smaller Catawba River area because there are so many excellent picnic sites with loads of trees.

The Paddy’s Creek area is much larger and (big bonus) has many more trails.

Paddy’s Creek also has a large beach and swimming/boating area with a huge parking lot and large covered picnic shelter (that is often occupied or reserved).

On Labor Day, the weather was gorgeous and, as you might imagine, the park was packed!

So why did I choose Paddy’s Creek on such a busy day?

I might have mentioned in a previous video that we recently purchased a used Volvo C40 Recharge EV (Electric Vehicle). While I normally charge it up at home, I’m trying to familiarize myself with charging on the go as well.

I’d read that Lake James has two (free!) convenience chargers at the Paddy’s Creek area. I drove to the site mainly to see where the were located. On such a busy day, I didn’t assume either of the chargers would be available–my plan was to find them, then head to the Catawba River access.

But turns out, the only available parking spot I could find at the Paddy’s Creek lot was one EV charging spot right there at the beach access and shelter! What!?! That’s an omen, I told myself, so I pulled into the spot, plugged in, and by golly, the car started charging.

I’m still new at this stuff, so it’s all a bit of magic to me. Forgive my excitement.

But where to activate?

The park was teeming with people all out enjoying the weather, the water, and the food and drinks. Truth is, I love seeing parks being enjoyed on this scale. Continue reading One Watt, Low-Profile QRP: A Labor Day POTA Activation at Lake James State Park
