My First Post-Helene POTA Activation!

On Friday, October 24, 2024, I performed my first POTA activation exactly one month (to the day) after Hurricane Helene swept through western North Carolina.

It felt oh so good!

As many of you know who’ve been following my Post-Helene updates, I simply haven’t had time to do POTA or SOTA activations. And even if I wanted to, most of the POTA sites around me are temporarily closed due to damage from Helene.

Truthfully, I didn’t start my day expecting a POTA activation. I’d planned, if anything, to make a short field radio video somewhere on my property, chase some POTA/SOTA stations, and make any other random contacts.

However, my daughter’s Shakespeare class decided to meet in person, so after dropping her off at 12:30, I had about two hours of free time. Before leaving home, I packed a couple of radio bags just in case I could find a spot for a POTA activation, or at least visit a local park to play radio for a bit.

I realized I was only a 20-minute drive from the Sycamore Flats picnic site in Pisgah National Forest (US-4510), where I’ve activated many times before. This site is in Transylvania County, which wasn’t hit as hard by Helene.

Google Maps showed the site as open, so I decided to drive over. Thankfully, it was correct! When I arrived, the front gate was open and there were a few visitors around.

I could tell the site had some storm damage—some tree limbs down and evidence of flooding from the Davidson River, which wraps around the area. The park service recently upgraded the picnic table pads, but the gravel had washed away, and many tables had either shifted or washed away.

That said, this site fared well compared to parks in Buncombe County. (Chimney Rock State Park is still inaccessible due to major flooding in the town of Chimney Rock.)

I hopped out, grabbed my backpack and TR-45L, and started recording my activation video.

Since no one was using the picnic shelter at the northeast end of the park (and it had no reservation sign), I set up there. I deployed my MM0OPX End-Fed Half-Wave antenna on a nearby tree, connected it to my TR-45L, and was ready to go!

On The Air

I hopped on the air and started calling CQ POTA. After the RBN picked me up and the POTA website auto-spotted me, the contacts started rolling in! Continue reading My First Post-Helene POTA Activation!

Offline QRP Activation

When you have activated the same park nearly 160 times, it starts to get a bit routine. Certainly, any day that you’re alive and able to participate in ham radio is a day to be thankful for, but I have to admit that lately I’ve gotten rather bored with activating from the Presidio of San Francisco US-7889.

Not a bad view from the activation location.

What could I do to spice things up a little bit? Recently, the W6CSN shack welcomed a new member into the QRP radio lineup, the venerable Heathkit HW-8. This got me to thinking about the days when the HW-8 was new, QRP was a niche part of the hobby, and the Internet was something that connected mainframes at universities.

Heathkit HW-8 Front Panel

That’s an idea! Try to activate a park for POTA without using the internet tools on which we’ve come to rely. The rules are: no self spotting on the POTA website and no looking at the POTA spots page to find stations to hunt. If you want to hunt, you’re going to have tune around and listen for stations calling CQ.

The HW-8 would not debut on this activation as it’s waiting on a power cord and we haven’t really gotten to know each other yet. Instead, the trusty KH1 would be the radio choice today, coupled to a quarter wave vertical on 20 meters and sending via the Bencher BY-1.

It is only fitting to use the BY-1 on a park bench.

I set up camp on 14.059 MHz and began calling CQ POTA with no prescheduled activation, no spot on pota.app, not even looking at my phone to see what the propagation numbers were saying. In fact, I only used my phone as a camera to take pictures for this field report.

Within a few minutes I got my first call, from Ken VE7HI. The next 40 minutes were spent calling CQ and hunting other stations until I had six contacts in the log. Then came the long, desolate hour of calling with no responses and being unable to break through any of the “pileups” around other activators. The drought ended with a P2P with NR1D/0 at Barr Lake State Park in Colorado and 15 minutes later the activation was complete with K6BBQ coming through for QSO number 11.

While the internet certainly makes it so much easier, this activation proves that the QRPer can be successful in POTA with just a 5 watt radio and a half decent antenna. If you are looking to spice up your POTA routine, why not give an “offline” activation a try?

Last year I reported, in a guest post here on QRPer, on the five POTA parks near my QTH that are linked by the Elora-Cataract Trailway, a rail trail that runs east from the quaint tourist village of Elora, Ontario, through the town of Fergus, where I live, through Belwood Lake Conservation Area and continues for approximately 45 km to the village of Cataract, on the Niagara Escarpment, well to the east. The trail passes through or near four POTA parks in my immediate vicinity, made easily accessible by foot, bicycle or vehicle, as one chooses. The Trailway is also part of the Great Trail of Canada CA-5082. In one of these nearby parks, Belwood Lake, it’s a 2-fer, making 5 parks in total.

In my original report I had also set a goal of one day activating the one nearby park I had yet to visit, and also to activate all five local parks in one day. With the summer quickly coming to a close here in South Western Ontario, and the fact that the one park I had yet to visit would close for the season in just a few days, it was time to attack my two goals with a rove! So I made plans to rise early, hope for cooperative weather and complete my 5 park cycle trip. Could I do it?

About 10 months ago, I took the plunge to design my own Morse Code transceiver. It was a crazy idea, and this was certainly a massive undertaking, but somehow, I managed to pull off this monumental task. The result of the project was the CFT1, a 5 Band CW Field Transceiver specifically tailored for POTA and SOTA operations. Doing this project was a great learning experience and despite the monumental effort and work I put into it, I really enjoyed getting to design a new product. There is something special when you see something you love and put effort into appear in the hands of others and seeing them enjoy using said product.

The purpose of this article is to outline some of the thoughts I put into when I designed the CFT1. It is not meant to go into the meat and potatoes of RF design work as there are plenty of resources out there that go over that stuff. I have yet to see much discussed on design philosophy of a transceiver so I thought it prudent to document these things. That is; what I took into consideration when putting together the radio. And as I learned in this project, when pulled off correctly, can result in a great product.

Apache case for the KH1

Many thanks to Tom (WW8D) who writes:

Hey Thomas,

This is Tom WW8D in Salem Va. I sure do enjoy your videos on youtube. I received a new KH1 yesterday and I just wanted to tell you that I have a clear waterproof case like the one you but its a slight bigger fromHarbor Freight. Its an Apache 550 and everything fits perfect in it.

Note from K4SWL:

I purchased the Apache 550 a few days prior to Helene hitting our area. I intend to make a post or video soon showing how this apache case compares size-wise with my Pelican cases. It is, in general, a much larger case than the M40 I currently use with the KH1. See photo below.

K3ES’ Unplanned activation of Yellowstone National Park

Many thanks to Brian K3ES who submits this awesome report.

As I write this report, we are currently visiting with my parents at their home near San Francisco, CA.  Getting here from our Pennsylvania home and back again is a continuing great adventure for my wife Becky, POTA Pup Molly, and me. You see, this is a grand road trip, complete with sight seeing, activating POTA parks in new-to-me states, and lots of driving.  While much of the trip has been planned, there have been frequent changes to the route and schedule, as better opportunities presented themselves.  One such opportunity was to deviate from interstate highway travel between Montana and Idaho, and divert to lesser-traveled highways.  This detour enabled us to fit in a drive through Yellowstone and Grand Teton National Parks.  Sadly, we were only able to take the time to see a small fraction of the natural splendor.  We did see enough to create the resolve to return for a proper exploration of the wonders that we had to miss.

The Welcoming Committee:  I had to stop again just after the entrance plaza leading into the park.  These elk, along with a number of their friends, were standing beside the road to greet us.
Mammoth Hot Springs.  To get this picture, Becky hiked along planked walkways and climbed a great number of steps.  Sadly we could only stop and look for a few minutes during our drive.

We made a handful of stops on our drive through Yellowstone, including a couple of hours at the Old Faithful geyser.  One challenge of traveling with Molly, is that dogs are not always welcome in interesting areas.  Another challenge is that, having been rescued from an abusive situation, she can respond unpredictably to other dogs.  So, Becky and I have often taken turns with one of us exploring the sights, while the other remained in the truck with Molly.  At this stop, Becky was the designated sight-seer for an impending eruption of Old Faithful (she takes better pictures), and I stayed in the truck with Molly.

*No explanation needed*
Becky got some great action shots Old Faithful!

VA2NW at Chillycon

Many thanks to Tom (VA2NW) for this report on Chillycon, aka Chilicon – Vince.

Canada’s capital, Ottawa, is the home of the Ottawa Valley QRP Society. The group holds an annual weekend camp-out at the Rideau River Provincial Park (POTA CA-0365) in early fall and it’s affectionately called Chillycon (also known as Chillicon). This year’s camp-out ran from September 20th through 22nd with some folks arriving a few days earlier. It’s a low key gathering which largely consists of casual operating, socializing, sharing tips and tricks, and checking out everyone’s portable radio gear.

On Friday morning I packed up my van with radio gear, camping equipment, and enough batteries to get me through a weekend of operating and cell phone recharging. Rather than tent camping, I decided to set up a sleeping pad in my minivan. The trip from Gatineau Quebec took a little under an hour, and I arrived just after 2:00pm local time.

Entrance to Rideau Provincial Park in Kemptville Ontario Canada

I brought my new toy with me, the Venus SW-6B (metal case + internal battery configuration). In just a few minutes I was on the air with the radio, an AlexLoop Hampack antenna, American Morse Equipment Mini-B paddle, and Apple EarPod wired headphones. I made several POTA contacts before it was time to start my shift as the Straight Key Century Club’s Canadian Straight Key Month special event station VC3Y/VE3. Conditions weren’t great and there wasn’t a lot of SKCC activity in the middle of a work day, so I only made one SKCC contact that day. After SKCC hour, I joined in on the weekly K1USN Slow Speed Test (SST). I contacted a few regulars, and then I returned to POTA and made another dozen or so contacts to bring the total up to 17 QSOs.

Sailboats at a lakeside activation

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

by Vince (VE6LK)

In August and September 2024 I was travelling around Southern Ontario for some family matters and naturally I brought my radio kit with me to squeeze in some radio therapy stops along the way. This is the report of my stop at CA-5362 Fifty Point Conservation Area.

It’s my second to last day here in Ontario and, as I wasn’t needed for other things, it was time to do a POTA rove and make the best of my last full day. I’m always on the lookout for a park that is within striking distance of wherever I am that I have not activated before and/or has not been activated before in either SSB or CW. So I planned a route to get to 9 parks and managed to get to 7 and activate 5 before other matters called for my attention. All were planned to be drive-up activations given the area and time constraints I was working within.

In my day job, I’m a Project Manager in IT, thus my style is that I plan before I arrive. You’ve already seen evidence of this with my POTA and Checklist tools that I’ve spoken about before. I usually do an in-depth study of a site before I depart, including reviewing linked webpages from the pota.app site, a satellite view and street view of the entrance on maps.google.com, and if it’s available, a 3D view of the area from maps.google.com. Let me know in the comments about the other ways you review a park before your arrival.

However I was pleasantly surprised when I found picnic tables with a view of the water at more than one of them! Balancing the good with the not-so-good, there were also some frustrations… I could not locate one of my planned stops despite driving up and down the road with two different GPSs blaring at me. My experience has shown that the smaller the park, the harder it is to find mapping, and this one from the Conservation Authority was no exception, and thus I abandoned it and drove onwards. Another site was right beside the roadway and high-voltage lines, and I didn’t have time to do a walk-in and get away from the noise floor. I always have a back-up site in my list for situations like this.

The Hamilton/Burlington/Niagara area is very pretty and, with a late summer happening around the time of a harvest moon, I didn’t mind the extra driving. For those of you who have been to Hamvention at Xenia it will be somewhat familiar as the area is full of gently rolling hills and lush green pastures. The humidity is also familiar, ugh, and one of the main reasons I moved away from this area in 1997. But nothing beats the view of sailboats out on the water; I have always found serenity in this -even knowing I get boatsick if I get on board!

The view from my “shack” at Fifty Point Conservation Area looking northwards onto Lake Ontario. On a clear day Toronto can  be seen in the distance. Today wasn’t a clear day, but still quite serene.

Fifty Point is a sprawling 80 Hectare (198 acre) area located on the southern shore of Lake Ontario at Winona. It has a top-tier restaurant, multiple beaches, pavilions and 330 slips for boaters, along with a camping area. It truly is a multi-use area! You can read all about it here (.pdf warning).

After locating the day use/beach area, I found a table overlooking the lake. As it was a mid-week day, there were plenty to choose from. The view was quiet with a few boaters enjoying the beach in the small bay directly in front of me.

A slip loop style bungee holds the feedpoint in place on the picnic table. My new-to-me Tiger-Cats hat proudly on display.

I set up my 40-30-20m trapped EFHW given the solar conditions. I’m so very pleased with the performance of this antenna and it has become the one I reach for the most when activating on this trip. It is about half the length of a conventional 40m wire and is resonant on 3 bands. It has me musing about adding 17m and 15m to it… perhaps N7KOM will offer such a kit?

When I built this antenna, I tuned it so that best resonance was in the middle of the CW portion of each band, and with the feedpoint located just a few feet off the ground and then sloped upwards at the endpoint. That’s how I deployed it this time around. As you see in the prior photo, my newly acquired Fishing Butler bungee strap held the entire thing firmly in place without any movement once I set up the mast. You can get them at Fishing World in Hamilton as they ship around North America. They stock multiple sizes so a phone call may be needed as their online store shows only one size. Ask for the assorted pack.

Trapped 20-30-40m EFHW to my Goture mast and spiral rod holder

Because I never was a Boy Scout and able to know where north is based on the position of the sun and time of day or how many chirps the cricket is giving <grin>, I consulted the compass on my smartphone. I unfurled my antenna and clipped it to the stop of the mast, walked the mast out to the length of the antenna and anchored it into the ground beside some Sumac bushes. With enough repetition, I’ve gotten pretty good at estimating where the far end of my antenna will be. It comes in helpful for parking lot activation and operating out of the trunk or your vehicle with a mast supporting the far end.

For these activations, and when I can, I’ve been orienting my antenna east and west so that it radiates broadside north and south so that I can capture the most number of hunters in North America. This is a contrast to how I normally operate from Alberta when my antenna is oriented to be broadside from southeast to northwest.

The activation itself was pleasant and I was surprised with visits from QRPer.com comment regulars KQ4CW and K5KHK – and I appreciate hearing from them often! 45 minutes after arriving I was packed up and on the road to my next stop.

Summary

We do POTA (and other programs) for various reasons. On this trip, it’s a break from life’s stresses. As I reflect upon my visits with various people, I realize that I’m quite blessed to know so many friendly hams no matter where I am travelling.

Big ships and 78GHz by chance!

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

by Vince (VE6LK)

In August and September 2024, I was travelling around Southern Ontario for some family matters and naturally I brought my radio kit with me to squeeze in some radio therapy stops along the way. This is the report of my stop at CA-6341 Welland Canal System National Historic Site along with CA-6096 Battle of Beaverdams National Historic Site.

This activation took a bit of research to figure out the intersection of the two given that the landscape had been dramatically altered from the time of the Battle of Beaver Dams in 1813. For example, at that time, the Welland Canal did not exist! So the town of Thorold has a park located at the west end of the battle site, and I was able to locate a monument at the east end, thus I was able to extrapolate and see that Lock 7 was in a direct path between the two. Thus I settled at Lock 7 for the activation.

A borrowed grocery cart serves as a mast support given the hard soil. Antenna runs off to the vehicle on the right.

This activation was done later in the day after my “Cross-Border Activation between Friends” and I was pleased to note the conditions had improved a fair bit.

I started off on CW, hunting other friends that were activating (shout-out to Ed W4EMB!) and then switched to SSB QRP where Steve KO4AFL found me and we had a brief chat before we both moved on. I stayed on 20m for this activation.

A quick drive-up activation means operating from the trunk

The Welland Canal is an engineering marvel that allows lake freighters to traverse the 100m/326′ height difference between Lake Erie and Lake Ontario.

Opened in 1833, it sees an average of 3,275 freighters during the shipping season which runs about 9 months of the year. With that sort of traffic, you can be reasonably assured that you’ll see one of these huge freighters on the day and time that you visit the area.

Summary

After my earlier activation with N2MAK, we drove down the Niagara Parkway past Niagara Falls and Niagara-on-the-Lake before arriving at the Welland Canal. It was a pleasant day and not terribly humid.

VA3ELE, Peter, with an attempt to set a new distance record on 78GHz

One last ham radio related story to the day was running into Peter (VA3ELE) about 1km from our home-away-from-home as he was attempting to set a new distance record with a friend who was well over 100km away.

Peter explained to me that his radio was 3W and the dish yielded 47dB of gain thus his ERP was around 14,000W see below. Needless to say that I did not stand in front of the dish.

[EDIT Sept 26] with gracious thanks to the math wizardry of David VE7EZM, the result of 47dB of gain with 3W of input is approximately 150,356W ERP.

All in all, labour day 2024 was full of beautiful scenery and lots of Ham Radio – exactly how a vacation day should be in my books.

QRP POTA: Pairing N3CZ’s Homebrew Transceiver with the TennTennas 49:1 EFHW!

On Monday, September 2, 2024, my good friend Vlado (N3CZ) and I spent Labor Day morning playing POTA.

Our first activation was at Lake James State Park, using the new CFT1 QRP transceiver. It was a lot of fun–you can read the field report and watch the video by clicking here.

For the second activation, I wanted to take Vlado to a site I’ve activated numerous times—one of my favorites—that he had yet to visit:

Table Rock State Fish Hatchery (US-8012)

We arrived on-site around 11:00 AM and, no surprise, had the place to ourselves. Honestly, I was hoping we’d see the three dogs that often pop by for a visit, but I believe they were on vacation with everyone else!

We both figured 20 meters would be our bread-and-butter band for this activation. More importantly, our transceiver was a 20-meter monoband (more on that below), so I deployed my new 20-meter end-fed half-wave antenna.

This particular EFHW is built on a  transformer by Walter (NE4TN) at TennTennas.

TennTennas 49:1 QRP Transformer

I may have mentioned before that Walter gave me this little 49:1 transformer at Hamvention this year when I met him in person. Walter is one of my top hunters in POTA, and I can often count on hearing his call when I’m on 40 meters.

Walter handed me this little transformer as a thank you, with no obligation to promote it—in fact, he didn’t even tell me where they could be purchased.

But I’m a sucker for home-grown mom-and-pop ham radio businesses, so of course, I’m going to plug it! He sells these on eBay (partnership link) for $39 each as a small side business. Not a bad price for a solid little 49:1!

As I mentioned, I trimmed this one for 20 meters, but I’ll likely make it a linked antenna with 30 and/or 40 meters as well someday.

Vlado’s Homebrew Transceiver

I was also excited that Vlado brought along his homebrew 20-meter QRP transceiver.

I had seen this radio in his shack during various stages of development, but I had never had an opportunity to use it in the field.

I’m not sure if Vlado had used it for a POTA activation yet, in fact.

His little transceiver is super simple but sports proper filtering, an OLED display, and, despite the large battery he connected to it, has modest power requirements.

He built it into an old Kenwood VHF radio chassis he found at a hamfest. I’ve been with Vlado before when he’s hunted for chassis for his various homebrew projects. The OM is always building or repairing something in his shack.

We were really looking forward to putting this little transceiver on the air!

On The Air

As with our first activation that day, we decided to take turns with one radio instead of setting up two stations. Vlado was the first op to start calling CQ POTA! Continue reading QRP POTA: Pairing N3CZ’s Homebrew Transceiver with the TennTennas 49:1 EFHW!
