An Awesome Day for Parks On The Air

11 Comments

by Teri (KO4WFP)

It is Wednesday, December 27th, the fourth day of my winter-break Florida POTA trip. The night before, we left the rainfly off the tent and were treated to a gorgeous view of the waxing gibbous moon. My brother Joseph was delighted and, while I worked on my article for that day, he lay back on his new Thermarest sleeping pad and took in the night sky.

I opted to sleep in until 8 AM enjoying the cooler morning air. Then it was time to get a shower and rid myself of four days of grunge. Breakfast was a leisurely affair. The mosquitos were less prevalent so I let Daisy relax on the tarp next to us and watch the comings and goings of our neighbors. But by 11 AM, I was getting antsy – time to head out and attempt two activations.

Google Maps

We drove east on the Tamiami Trail/US Highway 41 heading toward Big Cypress National Preserve (K-0659). The road is straight with guardrails on both sides as there is either wetlands or a canal on either side of it.  Occasionally there is a break in the foliage and the mangroves come into view.

Bird life is abundant in the area. We saw egrets, wood storks, cormorants, anhingas, and, my favorite bird, kingfishers. At my previous QTH in Savannah, I heard kingfishers at times but rarely saw them. On this drive, I saw eight or nine perched on the utility wires beside the road and gleefully noted each one.

We stopped at the Nathaniel P. Reed Visitor Center to pick up a map and figure out a place for my activation.

I chose the H.P. Williams Roadside Park as it was the closest place to the visitor center and had the opportunity for wildlife viewing. The parking lot was crowded and it was easy to see why. The site has a boardwalk from which one can view alligators and a nice picnic area in which several families ate lunch.

I found a tree away from the crowd and set-up the Tufteln EFRW. In the process of doing so, a little girl came up and peppered me with questions. Then her father and sister joined us. As soon as I was set up, I let them hear my callsign as well as the two girls’ names in Morse Code. It was nice to share my love of the hobby as well as Daisy, on whom they lavished some attention. What I think was a yellow-rumped warbler also paid Daisy and I a visit during the activation. Continue reading An Awesome Day for Parks On The Air →

WD8RIF takes his dog and his KX2 on a bicycle-portable POTA activation

Many thanks to Eric (WD8RIF), who shares the following field report via his website WD8RIF.com:

by Eric (WD8RIF)

On Saturday, November 4, 2023, I performed a successful bicycle-portable two-fer activation of Lake Hope State Park (K-1968) and Zaleski State Forest (K-5455) in Ohio as part of the Parks on the Air (POTA) program.

On a beautiful and warm early November afternoon, I bicycled the Moonville Rail Trail, on what used to the Marietta and Cincinnati Railroad (wikipedia article) right-of-way, from the tiny village of Mineral, through Zaleski State Forest, diverting from the rail trail near Lake Hope to ride to the Mountain Bike Trailhead overlooking Lake Hope within the state park, for my two-fer activation of the state park and state forest. I was carrying my KX2 Mini Travel Kit on the bicycle, and I was pulling my little dog Theo in a trailer behind the bicycle.

From the Moonville Rail Trail website:

This 10-mile rail trail takes visitors through the beautiful woodlands of southeast Ohio, including Zaleski State Forest; the communities of Zaleski and Mineral; and the Lake Hope State Park wetland areas. The corridor holds water on both sides of the trail, creating a wetland area that is home to numerous species of flora and fauna.

Additional points of interest along this trail are two unique and historic tunnels. King’s Hollow Tunnel (also known as King Switch Tunnel) is a 120-foot structure carved through the rock and lined by a series of 12×12 wooden beams. The Moonville Tunnel is brick-lined and has a long history of train accidents, earning the tunnel a reputation for being haunted.

After parking my car at Mineral, I began my ride on the leaf-covered Moonville Rail Trail at 1645 UTC and soon encountered the first landmark of the ride: the 120′ long, timber-lined King’s Hollow Tunnel.

Riding through the very dark tunnel and continuing west on the Moonville Rail Trail, I soon came to a succession of ponds. Rumor has it that a pair of nesting bald eagles fish these ponds, but I have yet to see them.

Continuing west, and now being well inside Zaleski State Forest, I soon came upon the brick-lined Moonville Tunnel.

After passing through the Moonville Tunnel, I was forced to divert from the Moonville Rail Trail and follow a gravel road before re-joining the Moonville Rail Trail about a mile further on. (When CSX abandoned the rail line in the early 1990s, they took everything: rails, ties, ballast, and all the bridges. Two of the bridges west of Moonville Tunnel have yet to be replaced.) I was pleased that my new narrow knobby bicycle tires were reassuring on the rough gravel road, but I can’t say Theo in the trailer enjoyed this portion of the ride much.

Back on the Moonville Rail Trail, and continuing west, the rail trail was almost 100% leaf-covered. Continue reading WD8RIF takes his dog and his KX2 on a bicycle-portable POTA activation →

Expect the Unexpected with POTA

by Teri (KO4WFP)

It was Monday, December 25th, the second day of my POTA winter-break trip in Florida. I chose Florida for this trip to avoid bone-chilling temperatures. What I didn’t and couldn’t avoid, though, was rain. The weather forecast before I left Bloomingdale, Georgia promised rain off and on during the first part of the trip.

Google Maps

I had two park activations planned for Monday, December 25th – Dade Battlefield Park (K-3615) in the morning and Little Manatee River State Park (K-1898) in the afternoon. After breaking camp at Paynes Prairie State Park and getting on the road early, a steady rain began as I drove southward toward my first activation. Well, phooey. I scrapped the Dade activation and headed instead for Little Manatee River State Park, the location of our next campsite.

Little Manatee River State Park is named for the Little Manatee River which flows 40 miles from a swampy area near Fort Lonesome snaking through the landscape before emptying into Tampa Bay. It is one of the few Florida rivers that were never significantly dredged or altered therefore it is one of the most pristine blackwater rivers in Southwest Florida. Park visitors can fish along or paddle in the river. There are also hiking and horseback trails in the park.

We arrived early at the park and, as it rained off and on, killed time in the car (much to Daisy’s dismay) until our campsite was available. The weather forecast had promised rain all day; but by 1:30 PM the worst of the rain appeared behind us.

We are stuck in the car!

My brother wanted to hike in the park and I figured why not work in an unexpected activation to make up for the one I planned but scrapped earlier in the day. The closest park not requiring an entrance fee was Moody Branch Wildlife and Environmental Area (K-6317). Daisy and I loaded up and off we went.

The 960-acres of Moody Branch was formerly used for grazing cattle and farming. It was purchased as a gopher tortoise mitigation park when developers needed an off-site alternative to on-site protection of rare species being negatively impacted by development. The site features hiking and horseback trails for the public and is managed with gopher tortoises and the Florida scrub jay in mind.

The drive was a pleasant one. We passed fields and fields of strawberries as well as plant nurseries. By the time we arrived at Moody Branch, the sun played peek-a-boo from behind the clouds and the wind vigorously whipped across the open fields and pastures across from the preserve.

Next to the parking lot was a small covered pavilion with a picnic table, but that was exposed to the wind. Walking past it and around a large oak tree presented a sheltered area. I snagged a branch, set up the EFRW antenna, and put my Helinox chair near the feed-end with Daisy lying down nearby. By this time, the sun was out and removing my hoodie and donning my goofy hat for the sun was a necessity. Continue reading Expect the Unexpected with POTA →

A Journey Through Florida Begins

It was Sunday, December 24th around 7:30 AM and my brother Joseph, my dog Daisy, and I were on our way to Florida. The purpose of the trip was to knock out nine or ten parks toward my goal of 60 new-to-me park activations in 2024. The trip was also designed to test my camping skills and adjust my equipment and set-up for future POTA camping trips. The first park on the itinerary was Olustee Battlefield Park (K-3642).

The drive to Olustee was straight forward: I-95 south to Jacksonville, then I-295 to I-10. We stopped at the Florida Welcome Center and snapped a quick picture despite the rain, then bundled ourselves back into the car and on our way.

Are we there yet?

Olustee Battlefield Park commemorates the site of Florida’s largest Civil War battle. Florida was important to the Confederacy in the Civil War because of its material contributions. In fact, Florida was a vital contributor of beef and salt. The battle of Olustee was fought to repel a Union attempt to disrupt Florida’s food-producing supply routes and recruit African-American soldiers. In fact U.S. African-American troops took part in the battle including the famous 54th Massachusetts regiment featured in the movie “Glory”.  A re-enactment of the battle at Olustee is held each February.

Joseph and I arrived at Olustee Battlefield Park under cloudy skies. Right after our arrival, a gentleman pulled up from the local area and began chatting with us. He owns some of the timber plantations in the surrounding area and was killing time at the park while a relative visited someone at the nearby prison.

I located a pine tree and installed the Tufteln EFRW antenna. Meanwhile, Daisy found a pine cone or two to deconstruct. It was nice to be at a location at which she could be off-leash and wander.

I began with 40 meters as usual but the noise on that band was horrendous – S7! So I moved to 20 meters figuring that would be quieter. NOPE! Again, S7! Well, shucks! I told myself to just call CQ and see what I could hear. Only the strongest calls broke through the noise and even then, I sometimes lost a hunter as the band appeared to be shifting. After twenty minutes on 20 meters, I switched to 17 meters hoping the noise might be better there. Nope – S7 AGAIN! I needed a few more contacts for a valid activation so I hung in there for five more minutes getting four contacts and then called it QRT.

What the heck could have caused such noise on all three bands I tried? There were power lines but I was nowhere near them. There were no other sources of noise I could see at the site. And then I remembered the nearby Baker Correctional Institution, the prison the gentleman’s relative was visiting. It was a large facility. Surely there was a lot of electric equipment with surveillance cameras, etc. That must have been the noise source.

It was time to move on. We drove secondary roads which took us through pine forests in the Osceola Wildlife Management Area and Gainesville, FL, home of the University of Florida. Continue reading A Journey Through Florida Begins →

KO4WFP: Was the Third Time the Charm at Cape Breton National Park (VE-0013)?

Many thanks to Teri (KO4WFP) for the following guest post:

Was the Third Time the Charm at Cape Breton Highlands National Park (VE-0013)?

by Teri (KO4WFP)

If you read my previous articles, you know my family and I went to Nova Scotia for a week. You also know that my first two attempts at activating parks in Canada did not go well. At the Halifax Citadel National Historic Site (VE-4841), I was sidelined by weather and site issues. At the Alexander Graham Bell National Historic Site (VE-4826), extremely poor band conditions and site issues prevented a successful activation. But those who know me well, also know I do not give up easily.

The morning of Friday, June 30th, my family and I headed to Cape Breton Highlands National Park (VE-0013) which occupies 950 kilometers of Cape Breton Island. One-third of the Cabot Trail, a world-famous scenic highway, runs through the park. Talk about amazing scenery! The highway runs along a shoreline reminiscent of the rugged California coast, then moves upward and inland on top of the highlands, a wild landscape with scrubby firs and moose crossing signs, and then descends back toward the coastline with steep ravines and valleys off the side of the road.

We arrived at the Cheticamp park entrance a little before 11 AM. Looking around the information center parking lot, I spied a tree and nearby picnic table perfect for my activation. This arrangement would allow me to watch for people who might walk toward my antennas and provide the use of a table to which I was more accustomed.

I immediately set about picking out a branch (located in the upper part of the photo below) and pulled out my arborist line and weight. Though I know I am not, I am beginning to feel like a pro putting antennas up in trees. I snagged the branch for which I was aiming on my first try. Hooyah!

One thing I have not learned yet is to accurately judge how much distance I need between my tree and my station. My antenna had too much slack so I hiked it up a bit higher in the tree and moved the picnic table about 5 feet.

KO4WFP: Part Two of Teri’s Nova Scotia POTA adventure!

Getting My Butt Kicked in POTA Yet Again

by Teri (KO4WFP)

If you read my previous article, you know my family and I went to Nova Scotia for a week. You also know that my first attempt at an activation in Canada did not go well. So, being a glutton for punishment, I attempted a second activation, this time at the Alexander Graham Bell National Historic Site (VE-4826) on Thursday, June 29th.

I learned several “takeaways” from the failed activation at the Halifax Citadel:

  1. look at the site in advance if at all possible,
  2. remember to check band conditions BEFORE the activation, and
  3. take all photos as the activation progresses because weather conditions may prevent you from doing so afterward.

After we departed the Halifax Citadel, we drove northward toward Baddeck, the town in which our next Airbnb and the Alexander Graham Bell site is located. Rain dogged us on and off until we reached Cape Breton Island. On the way, we stopped at Murphy’s in Truro for some of the best fish and chips and then The Farmer’s Daughter for ice cream, the consolation prize for my failed activation.

Being mindful of my first takeaway, we stopped into the Alexander Graham Bell site for reconnaissance before heading to our Airbnb. To my delight, there were trees present in the parking lot, though not many open branches over which to easily throw my line. I left for our Airbnb with the sun coming out from behind the clouds and an optimistic feeling about the next day’s activation.

My second takeaway from the Halifax Citadel was to check band conditions before the activation. Well, Thursday morning’s report was not promising. I didn’t see any mention of a geomagnetic storm (though one was forecast for Saturday), but the numbers were not good. What I didn’t realize was they were actually horrible.

We arrived around 10:10 AM and I began setting up the EFRW. It took me several throws to get the line in the chosen tree. Kudos to Thomas for recommending the arborist line. It never got stuck on any of the little twigs over which my line ran. The antenna was not as elevated as I would have liked but it was better than at yesterday’s activation and would work well enough.

KO4WFP: The Final Countdown and an Innovative Solution for My Nova Scotia Trip

Many thanks to Teri (KO4WFP) for the following guest post:

The Final Countdown and an Innovative Solution for My Nova Scotia Trip

by Teri (KO4WFP)

As I finalize preparations for my trip to Nova Scotia, during which I plan to activate six or seven parks, I ask myself “How the heck did I get here?” Those of you who read my first field report in this series know that Thomas Witherspoon’s decision to activate parks in Canada last year was my motivation. I admit it is gutsy of a relatively new op to believe I can undertake such a venture.

The necessity of traveling to Nova Scotia by plane drove the decision of what equipment to take. QRP became the name of the game, a great option for a CW op. I purchased the Elecraft KX2, a rig with a great reputation. Once it arrived in early May, I spent the next month and a half acquiring the necessary accessories and skills for this adventure. The final step before I leave is ensuring I have what I need and the room for it. Given others might want to undertake a similar venture, I will share what equipment I have chosen to take and how I am packing it.

I know most people prefer a roll-on suitcase, but after a trip to New York City last summer, I had enough of schlepping wheeled suitcases up and down the many flights of stairs we  traversed. Upon my return to Savannah, I immediately purchased an Osprey Fairview 55 pack. The Fairview pack can be carried as a suitcase by a handle on its side or as a backpack (my preference). As for its size, it meets airline carry-on dimension requirements for domestic flights and has a few points to attach items you might carry if actually using it for hiking. And, best of all, it is made for YLs!

Included with and attached to the front of the pack is a smaller backpack that can be used as a daypack. I figured this would be perfect for most of my ham equipment and proceeded to find a way to fit everything in it. The larger Fairview pack would serve as my carry-on and the smaller daypack as my personal item for the flight.

As you can see, the daypack has a fair amount of room. In the main compartment I have the gorillapod tripod for mounting the AX1 on top of the rental car or a picnic table, the carrying case for Craig, my KX2, and his accompanying items, and two Tom Bihn travel bins. There are two additional compartments inside the daypack – a mesh, zippered pouch and a slot for a laptop or iPad.

When I first began CW POTA activations, I used a notepad to track contacts. However, to save time, I switched to a refurbished laptop with N3FJP loaded to log contacts in real-time. Juggling it and the key didn’t prove as difficult as I originally thought. Also in the laptop slot are documents I don’t want bent like my license (not pictured), band plan, UTC conversion chart, and call sign prefixes for European countries. I am also taking a small steno notepad as a backup for logging contacts as well as making notes for the trip reports I’ll write afterwards.

In the zippered, mesh pocket are the Elecraft manual that came with the rig and my two longer lengths of RG-316, one 25’ and the other 50’. Continue reading KO4WFP: The Final Countdown and an Innovative Solution for My Nova Scotia Trip →

A New Skill and Antenna Leads to Success at Wormsloe K-3725

Many thanks to Teri (KO4WFP) for the following guest post:

A New Skill and Antenna Leads to Success at Wormsloe K-3725

by Teri (KO4WFP)

If you read my field report for Wheeler NWR K-0161, the trap dipole I used vastly outperformed the AX1 that particular day. I originally opted for the AX1 because, for my upcoming trip to Nova Scotia, my family and I will fly so space for ham equipment is limited. But the Wheeler activation convinced me to add an end-fed antenna to my kit for the trip, something several hams recommended. I chose the Tufteln EFRW QRP antenna.

Ham radio has taught me many things, one of them being I tend to procrastinate when I feel intimidated by a project. Case in point – the Pacific Antenna 2040 trap dipole I used in my last activation. My local radio club recommended it for POTA. (They were correct by the way – that antenna works well!) The project sat on my shelf for nine months before I got up the courage to work on it.

The same thing happened when I ordered a Morserino kit. I knew it would be a great learning opportunity due to my limited experience with electronics. Well, it took me three months to get up the courage to tackle that project. So, for whatever reason, getting antennas into trees fell into the same category in my mind. Now, having to use an end-fed antenna for POTA, I needed to learn the skill but had no idea where to begin.

Thankfully Thomas came to the rescue! I found his July 3rd, 2022 post discussing the various iterations of throwing equipment he used and on what he settled. Soon I acquired a Weaver 10 oz. weight, a spool of Marlow 2mm throw line, and a Tom Bihn small travel tray.

I next found Thomas’ Sept. 8th, 2020 post as to how to prepare the line (you tie it to a tree and tug hard on it several times to remove any kinks in the line), flake the line into a cube or bag, tie a slip knot to attach the weight, and then use one of two techniques for launching the line over a branch.

In my HOA, there is a wooded area that offered privacy and the perfect live oak branch, about 15 feet high, for my initial practice session. I opted for what is called the “granny toss”. Heck, if it was good enough for the arborist whose video Thomas featured in his September 8th post, it was good enough for me, no matter how ridiculous it might look. And guess what? Success on the third throw! OK. This skill was not proving to be nearly as daunting as I had assumed.

Now it was time to put this newly-acquired skill to use. Tuesday June 13th, I chose to return to Butter Bean Beach at Wormsloe (K-3725), partially to further my kilo pursuit for this park but also because I knew hams from my local club had used end-fed antennas there.

The drive to Butter Bean Beach from my home is a favorite. I take Ferguson Avenue which has a live oak canopy stretched over the road. The trees are dripping with Spanish moss and look like old Grand Dames swathed in grey boas.

Along the road is Bethesda Academy which used to be an orphanage for boys. The institution was established in 1740 by evangelist George Whitefield. Today Bethesda is a private boarding and day school for boys. The academy has a dairy and I often slow down to look at the cows with their calves in the pastures. You never know what you might see – I’ve actually pulled over to watch a newborn calf take its first steps. (How cool is that!) Today the cows and their calves were lounging in the afternoon shade of one of those Grand Dames. Continue reading A New Skill and Antenna Leads to Success at Wormsloe K-3725 →

Postcard Field Report: Pairing the Elecraft KX3 and Tufteln Random Wire

3 Comments

Believe it or not, the 2023 Hamvention and Four Days In May is only ten days away at time of posting.

Where in the world did the time go–?

If you’re going to Hamvention, I hope to meet you there. When I’m not floating around, I’ll be hanging out at the Ham Radio Workbench/Halibut Electronics table: 3011.

I’m super excited about attending, but I’ve so much to prepare in advance. Every day between now and then is planned out to the max with family activities and projects.

That, and being an introvert (this might surprise some of you), I have to mentally prepare myself for hanging out with 30+ thousand other human beings. I’ll need ten days for that alone. If I appear tired at Hamvention or FDIM, you’ll know why! Ha ha!

Postcard Field Report

I’ve got a load of videos in the pipeline and to keep from falling behind publishing them, you’re going to see more of my slightly shorter “Postcard Field Reports” for the next couple of weeks during my travels.

These postcard reports contain all of the core information, just less wordy.  (In theory!)

Tuttle Educational State Forest (K-4861)

On Wednesday, April 5, 2023, I had a bit of time in the early afternoon to do a POTA activation. Tuttle Educational State Forest was low-hanging fruit as my errands that day took me within a stone’s throw of the park.

I arrived a bit before noon and took some time to record a Hike and Talk video (which will be published in the next couple of weeks).

After the hike, I set up my Elecraft KX3 and paired it with my Tufteln End-Fed Random Wire antenna. Continue reading Postcard Field Report: Pairing the Elecraft KX3 and Tufteln Random Wire →

How to tune: Pairing the Emtech ZM-2 manual ATU with the Mountain Topper MTR-4B on the Blue Ridge Parkway

21 Comments

You’ve no doubt heard me brag about the Emtech ZM-2 ATU in previous field reports. I think it’s an accessory every field operator should have.

The ZM-2 is a very capable manual transmatch/ATU and is also one of the more affordable tuners on the market. It’s available as both a kit and a fully-assembled unit. Both well under $100.

I do believe the “manual” part of the ZM-2 scares off some and it really shouldn’t. We are used to simply pressing a button these days and allowing our automatic ATUs to do all of the matching work for us.

Manual ATUs do require some amount of skill, but truth is, the learning curve is very modest and intuitive.

Manual ATUs require no power source in order to operate–you adjust the L and C values by hand–thus there’s never a worry about the ATU’s battery being depleted. They also are easy to manipulate outside the ham bands because they require no RF in order to read the SWR–you simply make adjustments to the L and C until you hear the noise peak.   This is why many shortwave broadcast listeners love the ZM-2 so much. It’ll match most any antenna you hook up to it!

I also argue that everyone should have a portable ATU even if you operate resonant antennas. Think of an ATU as a First Aid Kit for your antenna: if the deployment is less than ideal, or if you damage it in the field, an ATU can help you find an impedance match your radio can live with. ATUs have saved several of my activations.

Mountain Topper MTR-4B V2

I’ve also mentioned that I’ve had an MTR-4B on loan from a very kind and generous reader for most of the year. He was in no particular hurry for me to send it back to him, but I wrote him in early November and said, “I’m doing one more activation with this little rig, then I’m shipping it to its rightful owner!”

He had a request, and it was a good one:

I think it would be a good little twist to the usual YouTube if you paired a random wire with the ZM-2 and the MTR-4B…showing how to tune the ZM-2 with a Mountain Topper…

I really liked this idea, so I made plans to to hit the Blue Ridge Parkway nearby and give it a go.

The first time I tried this in the field, I paired the MTR-4B with one of my Sony amplified speakers because the MTR-4B 1.) has no internal speaker and 2.) has no volume control. During the video, however, I realized that there simply wasn’t enough audio amplification so that the viewer would be able to hear a noise peak as I manually tuned the ATU. I decided to scratch that video and just do the activation on my own. I really wanted to show how the tuning process worked in the video.

I went back to the field the next week–on November 10, 2022–with my Sony in-line digital recorder knowing it would be much easier to hear how the L/C changes affected the band noise.
