Check Out Vince’s Quick Start Guide to SOTAmat!

If you’re not familiar, SOTAmat is an incredibly valuable app and tool for spotting yourself on the SOTA or POTA networks when you’re truly off-grid and outside the range of mobile phone service.

Check out this two minute intro to SOTAmat:

Setting up SOTAmat for the first time can be a bit confusing, but it’s not difficult. It is important, however, that everything is set up in advance of your SOTA or POTA adventures.

Our friend Vince (VE6LK) has just published a “Quick Start” guide to SOTAmat. It’s concise, and covers everything you’ll need to get set up and running with SOTAmat!

Click here to watch on YouTube.

Thanks for putting this tutorial together, Vince!

SOTAmat is an incredibly powerful resource for those of us who activate parks and summits in remote locations. I highly recommend downloading the app and making it a part of your SOTA/POTA tool kit!

A Recap of the 2023 W4 SOTA Fall Campout

Another W4 SOTA Fall Campout is in the books! What amazing fun.

This year, the campout was held at Lake Rabun Beach Recreation Area in north Georgia.

Once again, Joshua (N5FY), and I shared a campsite. He arrived Wednesday afternoon and I showed up Thursday afternoon around 2:30 PM.

There was quite a lot of wet weather in the forecast, so I opted to bring my large 6 person tent (the orange one above) instead of my two person ultralight tent. My thinking was that, if need be, we could us the large vestibule on this tent as shelter while eating and cooking.

Joshua was way ahead of me, though, and brought a canopy for the picnic table.

After pitching my tent and setting up, Joshua and I discussed how we should spend the rest of the afternoon. One thought was to try to squeeze in a SOTA activation, but we would have been fighting sunset at the end of it.

Instead, Joshua suggested that we build some antennas.

It was then I noticed that Joshua’s picnic table canopy had a built-in spool of 26 gauge wire!

I shouldn’t have been surprised. Joshua is the fellow behind the Tufteln brand of antennas. Turns out, he brought along a full antenna-building station.

I built a long random wire antenna and started a 30M EFHW.

That evening, we had friends pop by the campsite, ate dinner and fit in a quick POTA activation.

We didn’t have to drive to the activation site because our campground was in the Chattahoochee-Oconee National Forest (K-4473). Continue reading A Recap of the 2023 W4 SOTA Fall Campout

Gone Camping…

This morning, I’m hitting the road and heading to the W4 SOTA (Summits On The Air) campout at Lake Rabun Beach Recreation Area in the Chattahoochee-Oconee National Forest (K-4473).

I’ll be completely offline until late Sunday, save for any cell phone coverage I might receive on the summits we activate.  Obviously, I won’t be answering any emails or comments during that time.

I do, however, have a few Field Radio Kit Gallery posts scheduled to publish in my absence here on QRPer! Also, Eric, WD8RIF (who may only be learning about this at time of posting) will hopefully be able to monitor comments and approve any that are auto-moderated. Thanks in advance, Eric!

W4 SOTA

Once again, I’ll be sharing a campsite with Joshua (N5FY) and we hope to hit quite a few summits possibly with others.

N5FY juggling his HT and log book as S2S contacts were flooding in last year!

Since our campground is in K-4473, you can bet that we’ll be activating it during any downtime at the campsite. I’ve already scheduled activations each evening from 22:00-02:30 UTC knowing that will be the activation window and hoping the RBN picks us up to auto-spot to POTA.app (did I mention a lack of internet service–?)!

I hope to log some folks I don’t normally hear on the air.

Field Kit Gallery: NL5E’s Lightweight KX2 SOTA/POTA Alaska Backpacking Radio Kit

Many thanks to Eric (NL5E) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, read this post. Check out Eric’s field kit:


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.

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!

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. That way, if an external link is removed, it’ll still be safe and sound here. (We take our archiving seriously on this site.) Of course, we welcome links to blog articles and videos in your post.

Simply send your information via email to my callsign K4SWL at QRPer.com.

KM4CFT: A Relaxing Labor Day SOTA Activation

Many thanks to Jonathan (KM4CFT) who shares the following guest field report:


A Relaxing Labor Day SOTA Activation

by Jonathan Kayne (KM4CFT)

September 4, 2023

Days off from work can be a really great thing. And for someone who spends most of his time indoors at a computer, I try to find plenty of excuses to go outside and get some fresh air. Labor Day is one of those days I get off from work, so I decided I would do a SOTA activation, but I wasn’t entirely sure where.

Luckily, there are plenty of tools out there to help with planning a SOTA activation, namely sotl.as, which shows all the summits on a map along with additional information about the summit.

I wasn’t entirely sure which one to pick, so I just searched around and came across Evergreen Mountain, which has the reference designator W0C/FR-076. Doing some research showed that it was about a 2-3 mile hike to the summit from the parking lot, which was perfect. The air around Denver, CO can be somewhat thin and these hikes can be strenuous if you aren’t used to it. I have been living in the Denver area for 2 years and I still am not used to it!

After a small amount of planning, I pack my radio and antenna into a bag along with the usual hiking gear and drive to the base of the mountain. There were a lot of cars already parked there, so I had to park on the side of the road. It seems other people had the same idea that I did!

The trail to the summit of Evergreen mountain was comparatively easy due to the trail being designed for mountain biking. Mountains in Colorado tend to be incredibly steep, which can make them quite the workout, even if the hike is short. This trail consisted of plenty of switchbacks, which made the hike incredibly easy, trading steepness for distance. This was a massive bonus from my perspective!

As you might have guessed, Evergreen Mountain (and the town) get their name from the impressive number of evergreen trees in the area. As you drive towards the town, it almost becomes exclusively pine trees everywhere!

As I walked, I couldn’t help but notice all the fallen pine trees, which concerned me, but I quickly came across a sign explaining the reason.

I really got to enjoy walking through these trees, and listening to the wind howl through the mountains. It also had the benefit of keeping me nice and cool in the reasonable 83° temperature outside.

The trees also blocked the views of the mountains to some extent, but my research showed me that we get plenty of gorgeous views closer to the summit!

Right before the summit loop, I was rewarded with a small glimpse of the views that were to come!

I made it to the summit loop trail, and advanced to the last little bit before the summit. Right before the true summit there is a tenth-mile little trail that leads to a scenic overlook. I, of course, had to go and take a look.

I went back and made it to the summit. The top of the mountain was pretty flat so I just went to what I thought was the summit and set up my station there. Searching around showed that I was well within the activation zone. The area had some nice rocks to sit on as well as trees for me to lash my crappie pole to with para-cord.

I unpacked my gear and started to set up. The gear I brought was as follows:

With SOTA, I have the opportunity to use my VHF/UHF equipment to make some QSOs. I find it quite rare for me to do simplex communication on VHF or UHF these days as I almost exclusively operate on HF. Also, I like to try to operate in the parts of the bands with the lowest license requirement so that the less experienced hams have an opportunity to work me. With this, I can give our technicians a chance to chase SOTA! Continue reading KM4CFT: A Relaxing Labor Day SOTA Activation

QRP SOTA: Beautiful day for a hike to the summit of Bakers Mountain!

Sometimes, I crave a nice summit hike but don’t have enough time in the schedule to fit in a long one.

When I’m doing overnight trips to my hometown of Hickory, NC, my go-to spot for a proper hike is Bakers Mountain Park. The icing on the cake is that Bakers Mountain is also a SOTA summit (W4C/WP-007).

I wish Bakers Mountain Park was a POTA site as well, but at present the US POTA administrators aren’t including county and municipal parks–only state and national parks.

For more information about Bakers Mountain, check out this field report in the archives.

On Tuesday, August 1, 2023, I only had about 2.5 hours to fit in a hike and SOTA activation. That was plenty of time to hit Bakers Mountain!

Bakers Mountain Park has a nice long-ish loop around the perimeter of the park called the “Bakers Mountain Loop”; it’s about 2.75 miles long and has a reasonable amount of elevation change over the topography.

Adding in the spur trail to the true summit of Bakers Mountain, I’d say my total hike is about 3.25 miles or so.

Lookout platform on the Bakers Mountain Loop Trail.

Note that I actually include a bit of my hike to and off of the summit in the activation video below.

Setting up

Can you spot the MW0SAW EFHW hanging in the tree?

Once on the summit, I chose a spot to set up. Since I planned to deploy my 40 meter end-fed half-wave, I looked for a branch overhanging the summit perimeter trail.

Next, I deployed my trusty 40 meter EFHW that Steve (MW0SAW) made.

I also forgot my Tufteln/N0RNM knee board, so used my GoRuck GR1 backpack as a field desk. It worked pretty brilliantly, actually. Continue reading QRP SOTA: Beautiful day for a hike to the summit of Bakers Mountain!

N3HXZ: SOTA and POTA in the San Juan Islands!

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


SOTA and POTA in the San Juan Islands

by Dale Ostergaard (N3HXZ)

My wife and I like to take educational tour vacations from time to time. The outfit we mostly use is Road Scholar.

The tours are geared around education and immersion in local cultures and experiences. In addition, you meet a lot of like-minded people on the tour and make new friends.  Last summer we wanted to take a vacation to the pacific northwest. We had never been there and came across a tour through the San Juan Islands. The islands are located north of Seattle and east of Vancouver. Touring the islands is made easy on a guided tour as they arrange for all transportation between islands and on land.

Washington State has an excellent network of ferries serving the island which makes for easy connections to the islands.

After we booked the vacation I began wondering if there were SOTA and POTA opportunities on the islands. I quickly looked up sites on the SOTA Goat app and the POTA website.  Low and behold there was a treasure trove of parks and summits!

SOTA Map
POTA Map

Realizing the opportunity, I cross checked our itinerary with the parks and summits. The difficulty of course is that when you are on a guided tour, you have very little flexibility in the schedule, let alone transportation to go off on your own. After researching, I found 4 opportunities that included 3 parks and 1 summit. The parks were K-0061 San Juan National Historic Park, K-3223 Lime Kiln Point State Park, both on the island of San Juan, and K-3232 Moran State Park and summit W7W/RS-065 Mount Constitution on Orcas Island. The Summit lies inside the park so I had the opportunity to grab both with 1 activation. Continue reading N3HXZ: SOTA and POTA in the San Juan Islands!

Unveiling Poland: POTA, SOTA, and a Glimpse into History – Part 1: The Rover Award

by Thomas (DM1TBE as SP/M0KEU/P)

Just like last year, my family and I combined a visit to my parents near Berlin, Germany in the summer with some extra days in the region. As in last year, we went to Łagów (German: Lagow) in Poland.  The reasons we chose Łagów again, was a lovely holiday house, directly on a beautiful lake with a beach – all not too far away from Germany – and the good memories we had from our previous stay.

There is also a SOTA summit, which was only activated once in the 5 years when we visited the area last year. As I started with POTA this year and there are also a couple of POTA spots around, I thought it would be worth another visit.

The area around Łagów has been populated since the Bronze Age, i.e. >1000 BC. In 1251, the area came under German rule and the first mention of the town was in 1299. In the 14th century, the Knights Hospitaller built a castle that exists to this date. For the year 1367, it is documented that the convent of Lagow consisted of seven knights and one priest of the order.

At the foot of the fortress, a settlement for craftsmen and servants emerged, secured by defensive walls and two gates.

Gate in the middle

It is obvious that the builders of the gates did not have modern cars in mind when planing the size of the gates.

During the Thirty Years’ War, one of the longest and most destructive conflicts in European history, Lagow was captured and destroyed by the Swedes in 1640. The hand drawn map below from 1662 already shows Lagow.

During the fighting at the end of World War II in the spring of 1945, the castle and the village did not suffer mayor damages. After the war’s end in 1945, Lagow was placed under Polish administration, and Polish migrants settled in the area. The local Polish authorities expelled the native German residents who had not fled. The spelling of the town’s name was changed to Łagów.

Germany lost large parts of its territory as a consequence of the wars it has started after both major wars of the last century. Lagow was part of the lost territory depicted in the green area below.

The territorial gain probably wasn’t something Poland was very happy about, as the Soviet Union annexed a significant portion of Eastern Poland at the same time and incorporated the previously Polish soil mainly into the Soviet Union republics of Ukraine and Belarus. Consequently, the country experienced an effective westward shift.

Red: Pre-war Poland, Pink: Post-war Poland

Over a long time, expelled Germans were very vocal about claims to return the area to Germany and yet rather quiet about their share in the terrible events that unfolded between 1933 and 1945. Therefore, Germany’s eastern border was not recognized until 1990 by the German government. However, the issues resolved over the time and today, 33 years after the official acceptance of the border, no one I know even thinks about this as an issue any more. Additionally, the Polish side appears to be more relaxed about this topic. I have seen a lot of bilingual information panels and some memorials for former German inhabitants. Nice to see the wounds heal.

The Activations

The holiday house was within the borders of a POTA park. Having a 7-year-old “early bird” son, helped my to wake up early enough to get my 100 contacts for the POTA Early Shift Activator Award.  I walked to the edge of the facility and raised my SOTABEAMS Band Hopper III linked dipole for the 20-, 30- and 40 meter bands as soon as my son woken me up and ended my activity around 9:00 local time nearly every day.

Although I had a bunch of other antennas with me, I made all activations during my journey with this antenna and an Icom IC-705.

POTA Rover Warthog Award

The density of POTA-parks is way higher in Poland than in my home region in Southern Germany.  With the help and tips from Damian (SP9LEE) I drafted a plan to activate 5 parks on a single day. Continue reading Unveiling Poland: POTA, SOTA, and a Glimpse into History – Part 1: The Rover Award
