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?

The Design Philosophy of the CFT1: From concept to product

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.

Breaking the Speed Barrier at 1.8 Contacts Per Hour via CA-3459

9 Comments

Editor note – Please enjoy this guest post from Jeff Bourgeois VE7EFF.

Sometimes the elements just aren’t in my favor.  I knew activating Echo Lake Provincial Park CA-3459 would be a propagation challenge.  This POTA Park has never been fully activated before.  Last year one operator attempted it and was only able to log four contacts. Today, I not only had mountains to contend with, but apparently significant solar storms in action as well.

What initially made this activation so challenging is that Echo Lake is located on a valley floor and that it is surrounded by mountains on almost all sides.  I picked this particular spot to operate because it is the only location in the park that has a small window of opening to the South or South-South-East.  I was hoping I could hit enough stations in the USA to make a successful activation of 10 contacts.

Echo Lakes is about a 2-hour drive NE from my home in Kelowna, BC, and about 45 minutes ESE of Lumby, BC.  The last half-hour or so is on gravel roads. Now that we have arrived, my wife Alexis, VE7LXE, helps with unloading the gear,

This photo shows my narrow window of opportunity for southerly HF propagation.  Mountains on the left, mountains on the right, and mountains behind me.

As you can see below, the eastern direction is mostly blocked by a mountain and SE is the direction where I typically have the best success of traversing the USA.  I generally can’t rely on NVIS propagation; there just aren’t enough Canadian POTA chasers within NVIS range for me to make a successful activation.

Today,  I’m using my recently acquired Chameleon CHA Porta-Mount to support the 34’ (really only ~ 32’) carbon fiber telescopic mast.

Once again, I’m also testing my homebrew coaxial sleeve dipole, now cut for the 17m band.  I constructed it with RG-8X coax and terminated with a Fair Rite #31, 2.5” core as the RF block choke. My KX3 antenna tuner will take care of any SWR issues on all bands that I operate on.

Because I’m using a carbon fiber telescopic mast, I’ve previously noted that the mast has “significant” detuning effect on the antenna.  Thus, I operate it as a slanted coaxial sleeve dipole. This moves the antenna away from much of the mast influence.  The slant should also help with raising the propagation angle to hopefully clear the mountain tops (but not enough to make it NVIS).

The weather report was supposed to be mostly sunny.  However, it turned out to be just the opposite and was cloudy, threatening to rain, and somewhat cold. It’s colder outside than I care for and the fact that it is threatening to rain, I decide to operate from inside my 2016 Subaru Forester.  I only operate from inside my car when it isn’t viable to operate outside. Besides, I don’t want to risk getting wet today.

Now that my KX3 is fired-up and connected to the Bioenno 4.5 Ah battery and the antenna, I’m all set to see if anyone can hear me.  I should mention that I’m operating at 10W today so I guess that disqualifies me as a QRP operator. 😊

Here is the play-by-play report:

I started calling CQ on 20m at 16:55 UTC (09:55 PDT). My first contact came 15 minutes later with KN7D in Utah.  It took another 15 minutes to snag my next contact with WM2V in Arizona.

There’s not much happening for me on 20m, so I switch up to 17m.  At 17:40 UTC I log N5RLH in NM.  That’s it for 17m. Moving up to 15m, I snag a contact in NC with N4EX at 17:52. That was my only 15m contact of the day.

I went on to try 12m, 10m, and even 30m.  Absolutely nothing over the next hour of calling CQ on those 3-bands. Back down to 20m.  One contact with KE4KE in Minnesota. It took an hour and 15 minutes more to land just one more contact on 17m with KB6FPW/P in California at 21:00.

I’m definitely not breaking any speed records today. A tortoise could probably log more contacts than this.

Another hour passes until I land a contact with K0SX in Colorado on 20m.  Suddenly, 20m picks-up steam and I land 4 more contacts on 20m – two in California and two in Colorado between 22:00 and 22:47. I’m almost at the end of the POTA UTC day for this park, but I’m determined to try to pick up more contacts before 00:00 UTC.

Last crack at 17m band.  At 23:13 I land KJ7BS in Arizona. As my final contact of the UTC day, I snag KD7DUG in California at 23:15. I keep calling CQ for the next 45 minutes with no more results.  It is now 00:00 UTC and the POTA day is over.

But something drives me on to keep calling CQ. I keep thinking propagation will get better.

At 00:05 I log my last contact of the day on 20m – a P2P QSO with AF0E in Colorado.  I realize that this contact will have to go into the next day’s POTA log, but a contact is a contact. At the end of the day, I logged 13 valid POTA contacts, plus 1 into the next UTC day.


Tip:  Click on the map for a larger image view.

The Contacts Map above does seem to confirm that my narrow corridor of propagation was primarily due-south or SSE – squeezing through the mountains opening.  Some magic of propagation handed me North Carolina and Minnesota.

This is by far the hardest I’ve ever had to work to get sufficient contacts to activate a new park.  I was determined to get this park activated, though.  It took 7 hours of calling CQ to log 13 contacts. That’s a record 1.8 contacts/hour!

I don’t think the antenna is the real culprit for today’s weak results, especially considering that 6-days earlier I logged 68 contacts including 8 DX stations in Europe via Inonoaklin Provincial Park CA-3626 using this same antenna configuration. I wont get any awards for logging the most contacts per hour – but perhaps I qualify for an award for the least number of contacts per hour!  They could call it the Snail Award.  😊

Between being surrounded by mountains and muffled by solar storms, it was a challenging day. Time to pack-up and make the 2-hour drive back home before it gets dark.

Elecraft KXPD2 paddle
Bioenno 4Ah battery

Conrad has a sunny and beautiful activation at Silver Sands State Park

Editor note – Please enjoy this guest post from Conrad Troutmann N2YCH.

Thank you “deputy” Vince, VE6LK, for assisting in managing some guest contributor posts for QRPer.com. I’m so happy to hear Thomas and his family rode the storm out safely and send him my best wishes and hope things return to normal soon. Here’s my contribution to help keep QRPer.com going while Thomas gets his house back in order. 73, Conrad, N2YCH

 

September 22, 2024

Lately, the high frequency bands (15/12/10 meters) have been hit or miss, largely due to recent space weather events. Today, taking a look at WSPR beacon reception at my QTH on the Top Spotters web site, I noticed that 10 meters was open and I was spotting quite a few stations on the band.

Top Spotters Ranker – https://wspr.rocks/topspotters/

The weather here was sunny and beautiful and my batteries were all charged up, so it seemed like all signs were pointing to a POTA activation at Silver Sands State Park, US-1716. I usually activate on 20 meters, however with 10 open, I thought I’d try for some DX and give hunters that don’t normally hear me on 20 a chance to get the park. When I was trying for my Worked All States POTA award, I appreciated it when the Hawaii and Alaska activators activated on the higher bands so I had a chance to get them all the way from the East Coast. I like to return the favor when I can.

I decided to give my Elecraft KX2 a workout as well. Paired with my Buddipole vertical up 10’, I figured I would do well.

I got set up, checked and adjusted my computer time using JTSync and started calling CQ POTA on FT8. I called and called and no one answered. I checked PSKReporter and I was being spotted, but still, no answers. I was receiving well, in fact, I was picking up stations as far away as South Africa. “Hello, is this thing working? Can you hear me now?”

Just to be sure my equipment was working, I shifted to “hunt and pounce” mode. Rather than call CQ, I started answering stations who were calling CQ. It’s not my preferred way to get the QSO’s needed to officially activate the park, but sometimes that’s what you need to do. I have JTAlert set to sort received stations from strongest received signals to weakest. I’ve found based on prior experience that my chances of completing a QSO are much higher with stations that I’m receiving with strong signals. So, I answered a CQ for a station in Texas coming in at +19 and he answered right away. One in the log.

I did this for the next 30 minutes or so and managed to get six stations, about half I called and the other half answered my CQ. I moved around the waterfall looking for openings, but it was busy and challenging. Just for grins, I decided to see if FT4 was active. Sure enough, I was receiving many stations there as well. I called CQ and immediately had stations answering. I did the rest of the activation on FT4 and had a steady stream of callers. I completed the activation with 17 total QSO’s, my map is below.  I make these maps using the Adventure Radio log analyzer. You can import the same log you upload to the POTA page and put the grid square in and it generates the map.

Interestingly, all of the USA contacts were on FT8 and when I moved to FT4, I picked up all of the EU ones. I was happy to see after I uploaded my log to the POTA site that almost all of the hunters who got me were active POTA hunters and had accounts at the POTA web site. In fact, one was actually a park-to-park QSO. PA4PA was at the Sluiswaai Nature Reserve, NL-0219 in the Netherlands.

Equipment I used for this activation included:

 

Mission accomplished!

K3ES’ Unplanned activation of Yellowstone National Park

11 Comments

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!

Uncharted Trek into Trout Creek Ecological Reserve, CA-4221

6 Comments

My goal for this summer is to do more backpacked day-trip POTA activations while I’m still physically able to. This is my 4th backpacked-in activation this past week or so. And a thank you to Thomas K4SWL for letting me share my adventures from the Canadian out-back.

Today’s goal is to activate Trout Creek Ecological Reserve, CA-4221 which is about one-hour drive south of Kelowna, BC, Canada, which is where my wife Alexis (VE7LXE) and I (VE7EFF) have lived for the past 12 years. Alexis accompanies me on all my POTA activations.

It is a beautiful late August day. The temperature is expected to be about 31℃, or 88℉.  The one-hour drive is just the beginning of the day’s adventure. We were able to conveniently park at the Summerland Golf and Country Club, but this is where all conveniences end for us.

Trout Creek Ecological Reserve has never been activated before – I’ll be the first. It’s no surprise this reserve hasn’t been activated before. It’s all wilderness with no trails to follow. I have to rely on my Garmin 66sr GPS and Pixel8 smart phone with Google Maps with Satellite View to help me navigate to and through the reserve in search for an optimal operating location.

I expected the trek to only be about 1 Km in with about 600 ft elevation gain. It’s all uphill, all the way. From the golf course parking lot, the hike starts out relatively easy. At first, there appears to be some semblance of a trail.

Two in One Day for the POTA Babe

4 Comments
by Teri KO4WFP

After striking out at Pinckney Island National Wildlife Refuge, it was time for this POTA Babe to get back on track with my goal of 60 new valid park activations for 2024. As much as I enjoyed the historic sites and the refuge I recently visited, I needed to return to activating wildlife management areas.

Wildlife management areas (WMAs), properties set aside for conservation as well as hunting and fishing, are plentiful in the state of Georgia. Georgia has 163 WMAs and 38 are located within 75 miles of my home QTH. So it makes sense I would include those in my 60 new activations pursuit.

I set my sights on Morgan Lake WMA (US-9791) and Griffin Ridge WMA (US-3752) because  they are an hour’s drive from my home and across the road from one another. Talk about convenient!

map source: worldatlas.com

Daisy and I set out early Tuesday, October 1st. During the drive, I encountered two groups of ambulances moving north on Interstate 95. At a rest stop, several EMTs from one group were taking a quick break and wore t-shirts with “Disaster Relief” on them. It was a reminder of the recent events due to Hurricane Helene.

I chose to activate Morgan Lake WMA first.  According to the map, most of the property appeared to be wetlands but there is a boat landing for fisherman to access Morgan Lake. In fact, the road you use to reach the landing is built up a good 10-12 feet, I assume, to provide access even when the area experiences flooding.

WMAs vary in their presentation. Some are nicer than others with shooting ranges and gravel roads. Morgan Lake was, frankly, on the dumpier side. This was not the place to come to commune with nature. But no matter. I was here to do an activation, so I set about getting my equipment up and running.

I opted for the Chelegance MC-750 today. Attempting two parks in one day meant I needed a quick and easy set up and a vertical would provide that.

Despite poor band conditions at some of my past activations, today the bands were great! (You’d really want that on a day you are attempting back-to-back activations.) Even better, I had internet access at this park, though it was on the slow side. I could spot myself (always a plus) and it wasn’t long before calls began coming in once I was spotted on the POTA website.

Forty meters gave me 15 contacts in 20 minutes – not bad! It was good to hear so many from the southeast, some I hadn’t heard from in a while. Given I had a second activation to attempt and I wasn’t thrilled with the site conditions at Morgan Lake, I called QRT after contact #15, packed up, and headed across the road to Griffin Ridge WMA.

QSO Map for Morgan Lake WMA (by home QTH) source: http://tools.adventureradio.de/analyzer/

Griffin Ridge is a much larger WMA than Morgan Lake. The park has two access points from the road and I chose the one farther to the north as it looked the more inviting of the two.

Map for Griffin Lake WMA. source: GA DNR

Again, given I was short on time today, I found a little area off to the side near the information kiosk by the road. If I visit this WMA again, I’ll drive further in and find a place away from the road noise.

entrance to Griffin Ridge WMA

The little place I found was somewhat shaded which Daisy and I needed given the warm weather. The day had been mostly overcast; however, I’ve learned to not trust that will persist. Nothing like being in the middle of an activation and the sun comes out from the behind the clouds to roast you.

the spot I found just perfect for parking Kai

For the North Carolina trip this past July, I purchased a Mountain Laurel Designs shelter. It was handy for my SOTA activation at Black Balsam Knob. I figured it would also be useful for POTA activations in the heat. Since I can activate next to my car for POTA, I used the front and rear wiper blades as well as the roof rack to attach three sides of the tent and the surrounding foliage to which to attach the other two. My hiking pole was not tall enough to support the center, so I used the outer rear door handle on the car to elevate the bottom of the pole to give me enough height so I could sit in my Helinox chair under the tent. It was not the best setup but good enough for today. I need to give more thought how to better support and use the tent as a shelter with my car.

Daisy relaxing

We all know band conditions fluctuate throughout the day and I hoped they would hold up for my second activation. Guess what? They did!!!

I opted for 20 meters given it was nearly noon and had 39 contacts in a little over an hour. I was thrilled! That is a “good” thing about bad band conditions. When the bands behave, you really, REALLY appreciate it.

view from under the tent at my QTH

As I packed up my equipment, I reflected on the two activations. Of the two, I would return to Griffin Ridge. The foliage and landscape reminded me of Canoochee Sandhills WMA; however, it was nicer than Canoochee and not nearly as remote, which could be considered bad or good, depending on your perspective. I would definitely set up farther inside the property to avoid the road noise unless it had rained a lot prior to my visit. The road into the property was quite sandy and soft and deep in some spots. My car might not be able to navigate those conditions after a heavy rain.

A valid activation at these two parks put me at 41 out of the 60 new park activations for which I am aiming in 2024. There are only three more months of this year so I am running out of time to reach my goal. It would be easy to accomplish my goal if life didn’t keep getting in the way, right?

There are still plenty of wildlife management areas to consider as well as properties closer to the coast as I continue my pursuit. Where will I show up next? Stay tuned…

Experimental Antenna Reins-in Surprising Results

14 Comments

Editor note – Please enjoy this guest post from Jeff Bourgeois VE7EFF.

Today, September 6, I hope to POTA activate Inonoaklin Provincial Park CA-3626 in Southern BC, Canada, located on the shores of the Lower Arrow Lakes. On this activation, I will be using my novel experimental homebrewed Coaxial-Sleeve Dipole. The results were surprising!

We have been wanting to come back to this park since a brief visit to the area last summer.  I especially wanted to come back because, at that time, it had never been activated by anyone. I had plans to activate another park in the area that day.  Unfortunately, I was beaten to the draw just a few weeks ago by another ham.

The other reason I didn’t get here sooner was because it is a 3-hour drive east from our home in Kelowna, BC. 3-hours is pushing the limits of how far I’m willing to drive on daytrips, especially in mountainous areas. We rarely, if ever, do overnight trips.

We left the house very early in the morning on Sept. 6, 2024.  While the countryside is very beautiful enroute to the Arrow Lakes, I kind of dread the drive as the roads are often narrow, twisty-windy and up and down steep mountain passes.  At times it felt like being on a roller coaster.

Big ships and 78GHz by chance!

4 Comments

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!

2 Comments

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!
