A Hasty Activation in Georgia

4 Comments

by Teri (KO4WFP)

As many of you know, my personal life has been tumultuous these past five months. I thought maybe it would settle down after the first of this year but no such luck. My son and I moved into a townhouse the third week of January. While I appreciate my parents upending their lives to accommodate the two of us during my divorce, there were too many people in too small of a house with too much stuff. Also, my son needed a room of his own which he didn’t have at their place.

Moves are never convenient and this one was no exception. I needed to be packing the Sunday prior to my early Monday morning move. However, I had already committed to and scheduled an activation at Oliver Bridge Wildlife Management Area (K-3764). The weekend of January 20th and 21st was the winter Support Your Parks weekend and, as a POTA Babe, there was no way I would miss the event!

Support Your Parks information on POTA website

Thankfully, Oliver Bridge Wildlife Management Area (WMA) is only 40 minutes from my parents’ home. That meant another pleasant drive in rural Georgia on GA Route 17 through the communities of Guyton, Egypt, and Oliver.

Google Maps

This WMA consists of 1,560 acres and offers hunting for deer, small game, and turkey. Checking the Georgia Department of Natural Resources Hunting Regulations guide, the only item in season this particular weekend was small game. I would make sure to take the blaze orange vests for both Daisy and me again.

The WMA is bounded on one side by the Ogeechee River, one of the few free-flowing streams in Georgia. This blackwater river runs southeast 294 miles to empty into the Atlantic Ocean at Ossabaw Sound near Savannah. It played an important part for trade and commerce as well as was a source of freshwater and food for communities along its banks. In present day, kayaking and canoeing are popular pastimes on the river as well as fishing.

Daisy and I arrived at the WMA a little before 11 AM. We took River Road in the park to find a place for the activation. The road was in rough condition in some spots and was another one I’d not want to drive immediately after a heavy rain. I was thankful, once again, for my four-wheel drive Subaru Crosstrek nicknamed Kai. (My family has a funny habit of naming all our cars.)

On the map, there appeared to be a clearing about two-thirds of the way down the road. Tall, skinny pine trees lined either side of the road, not great for getting an arborist line into them. Thankfully, the canopy opened up for a small clearing as I surmised from the map and it was here I decided to set up.

Because of the opening, the pine trees near the side of the road had some lower, reachable branches on them. After a few tries, I snagged the branch I wanted and began hoisting the Tufteln EFRW antenna with the arborist line.

In past activations, I would usually get the antenna up however I could. But, at this point in my POTA journey, I am beginning to think how I want the antenna oriented with propagation in mind. I wanted it to run at a diagonal – northwest to southeast. To do that, I’d have to get it across a wide ditch that was partially frozen due to the cold temps. However, if I just tossed the line across, it was light enough it would likely end up in the ditch where I couldn’t easily retrieve it. Continue reading A Hasty Activation in Georgia →

More Surprises in Florida

It is Friday, December 29th and my winter-break POTA trip is drawing to a close. My brother Joseph and I are spending Friday and Saturday nights at an Airbnb after six days of camping. However, before we do that, I have two more parks to activate today – Green Swamp Wilderness Preserve (K-5330) and Lake Apopka North Shore (K-8353).

Google Maps

Overnight, a cold front began its march through Florida. We woke to temperatures in the low 50’s and a brief glimpse of the rising sun before clouds took over the sky again.

The drive to our first park – Green Swamp Wilderness Preserve – was a pleasant one. The preserve is divided into five management districts. We ended up in the West Tract as that is what I chose in Apple Maps. There are 65 miles of hiking trails though the tract is also used for hunting, canoeing, fishing, camping, and equestrian activities. There is a variety of habitats in the preserve – sandhills, flatwoods, oak hammocks, river swamp, and cypress ponds.

I chose an oak tree just inside the West Tract entrance perfect for the Tufteln EFRW antenna. A sunny location was necessary as the temperature was chilly in the breezy conditions. As I set up, two ladies rode in with their horses. Salty, a red roan, was unsure of Daisy and I at first. However, he eventually settled down enough to walk by and check out my POTA flag. Being a horse owner previously, I have a soft spot for these intelligent and sensitive creatures.

Salty and his owner

When Salty moseyed on, Daisy and I got down to business. I went straight to 20 meters which had no noise at all. In 35 minutes, I had 20 contacts. I needed to wrap up the activation soon to have sufficient time to fit in the second activation today but thought I’d check 17 meters for any DX contacts. I had four contacts on that band including Etor FH4MN in France!

In short order, I packed up my equipment and we headed to Lake Apopka with a stop at Costco for gas. On the drive, we saw five sandhill cranes. I had heard sandhill cranes at Little Manatee River State Park while walking Daisy one day. But I never spied them. These cranes were wary of me and the pictures I snapped weren’t great.

We finally arrived at Lake Apopka North Shore which features an 11-mile wildlife drive. The park reminded me of the Savannah National Wildlife Refuge back home in which I’ve spent some time. Lake Apopka is the headwaters of the Ocklawaha Chain of Lakes. The North Shore area consists of former farmlands that are now used to clean up Lake Apopka’s waters by circulating the lake water through restored wetlands thereby filtering it before it is returned to the lake. Those former farmlands polluted the lake with phosphorous which caused a host of problems. Continue reading More Surprises in Florida →

An Awesome Day for Parks On The Air

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.

Big Cypress National Preserve Visitor Center

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 →

Expect the Unexpected with POTA

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

10 Comments

by Teri (KO4WFP)

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.

QSO map for Olustee Battlefield HSP http://tools.adventureradio.de/analyzer/

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 →

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 →

QRP by Lantern Light: A CW/SSB sunset POTA activation at Lake James State Park

3 Comments

The one thing about doing POTA activations in the winter is being aware of just how short the days are. It seems like, lately, I’ve had a number of activations that have spilled over well beyond sunset.

With POTA, running out of sunlight really isn’t a big deal. As long as I have a headlamp (I always do) and/or a lantern, I can continue operating as long as the park is still open to guests.

With SOTA, running out of sunlight can develop into a serious situation, especially if you’ve bushwhacked to a summit in unfamiliar territory. Even with a headlamp, it can be difficult finding your way back to an established trail.  I’ve never scheduled a SOTA activation that pushed sunset unless I’m comfortable with the path to the summit.

If I’m being honest, I think a part of me actually enjoys doing POTA activations after sunset. It feels a lot like camping.

On Sunday, December 4, 2022, I was on the road once again and could not help but squeeze in a POTA activation at Lake James State Park.

It was late afternoon and I knew I’d be pushing sunset, but I had my little LED lantern just in case I ran out of sunlight (hint: I did!) and I was ready to play some radio: both CW and SSB!

Lake James State Park (K-2739)

It was a grey, chilly day and there were no other cars in the parking lot at the Catawba River Access. I had the whole park to myself until closing time at 7:00PM.

I chose a picnic table by the lake, putting some distance between me and the visitor’s center which has been known to spew radio interference (QRM) in the past.

I brought along my Elecraft KX3 for this activation.

The KX3 is one of my top field portable radios, but I rarely take it to the field these days for a couple reasons:

  1. It’s my main shack radio and is hooked up to my KXPA100 amplifier 100% of the time (although I rarely run enough power that the amplifier engages). I do much of my park/summit hunting from home with the KX3.
  2. Since I purchased my KX2 in 2016, I tend to take it to the field instead since it’s *that* much more portable. It’s like a smaller version of the KX3 with nearly the performance and only lacking 160 and 6 meters.

But I do love my KX3. It’s a benchmark radio–and one of the best field transceivers on the market.  You will see a few field reports with it each year since I try to give all of my radios a regular dose of fresh air!

Setting up

After recording the intro to my activation video (which I tried to do before the sun actually set), I decided to film the antenna deployment as well.

I debated which antenna to use at the site. I decided upon the super easy-to-deploy 28.5′ “no transformer” random wire antenna by Tufteln (see link in the Gear section below). I first demoed this super simple antenna on Mount Mitchell during a SOTA activation. It’s basically two lengths of 28.5 foot 26 AWG wire connected to a BNC connector on a small 3D printed mount which provides strain relief.

This antenna is basically my super simple speaker wire antenna, just in a more compact form factor.  Since there’s no transformer, the antenna relies on an ATU to do all of the heavy work of sorting out impedance matches.

Arborist throw lines: Ideal lengths, weights, and packs for field radio

19 Comments

Many thanks to Barry (WD4MSM) who writes:

Thomas,

I thoroughly enjoy the website and movies!

Could you answer one question?

How much arborist throw line do you take into the field? 150’ – 100’ – less?

Thanks for taking the time to answer.

Barry WD4MSM

Great question, Barry!

I basically have four variations of throw line kits.

You’ve asked about line lengths, but I’m also asked frequently about the throw weight sizes and throw line bags as well.

First, let’s take a look at my kit variations, then I’ll share my thoughts on throw line lengths, weights, and bags. Note that many of these products are Amazon so there are affiliate links:

Throw Line with folding cube

One is my original Weaver throw line kit made up of two parts:

The line length is 150 feet (45.72 meters).

I tend to use this throw line when I’m doing a POTA activation very close to my vehicle. It’s lightweight, but a bit bulky to take on a long hike.

Compact Arborist Throw Line Kit

This kit is identical to my large folding cube kit above, but the throw weight is 12 oz and I store it in a small Weaver stuff sack.

The arborist throw line is an invaluable field radio kit tool

19 Comments

Two days ago, I activated Parc national des Grands-Jardins (VE-0499)–a stunning national park here in the Charlevoix region of Québec, Canada.

As soon as we drove up to the activation site I had researched in advance, I surveyed the picnic area and mentally noted the best spot to deploy an end-fed half-wave using my trusty arborist throw line.

With the throw line’s assistance, I had an antenna deployed within a couple of minutes max.

It hit me then just how invaluable a tool the arborist throw line has become for the types of park and summit activations I do.

Pre-Throw Line Activations

During NPOTA (National Parks On The Air) in 2016, I wasn’t aware of arborist throw lines and had been using some high test monofilament fishing line attached to a weight.

The fishing line was strong enough to support my QRP antennas and I could typically reuse the same length of line for 2-3 activations. Eventually, the line stretches and weakens thus it must be cut off and discarded.

Never again

I’m a big Leave No Trace kind of guy, so am embarrassed to admit that during one activation, my fishing line snagged high up in a tree and left a bundle of broken monofilament in a spot where I could not retrieve it. This was deep in a forest and although I doubt anyone will ever see it, I know it’s there. It bugs me to this day and if I ever sort out a way to remove it, I certainly will.

This occurrence was one of the catalysts for purchasing my first arborist throw line kit.

That throw line kit absolutely revolutionized my antenna deployments by:

  • increasing the speed deployment,
  • increasing accuracy,
  • allowing me to re-use the same line hundreds of times,
  • and being orders of magnitude more reliable and stronger than fishing line.

It changed everything and I’ve never looked back.

Since that first throw line kit (which I’ve lent to a newly-minted active ham), I’ve built four more throw line kits.

Compact Weaver Throw Bag

In early 2021, I purchased a second throw line and 12oz weight (identical to my first) for backpacking along with this compact Weaver Leather throw line storage bag (affiliate links).

I was searching for a more SOTA-friendly/backpack-able solution than the arborist throw line cube.

I was very skeptical about how easily this bag would work in the field. One of the reasons my throw line storage cube works so well is because the opening is large allowing the line to deploy without tangling. Packing up is fast because the line can be flaked back into the cube in a matter of seconds. Continue reading The arborist throw line is an invaluable field radio kit tool →

How to pack a compact Arborist Throw Line Storage Bag

15 Comments

Since last year, I’ve become a bit of an arborist throw line evangelist.  Arborist throw lines have made my wire antenna deployments so quick and easy compared with using monofilament fishing line or more complicated systems.

Since purchasing this arborist throw line last year, I’ve never looked back. The throw line never gets caught in tree branches, it’s reusable hundreds of times, and with it I can easily snag branches 50’+ above the ground to hang my wire antennas.

When I purchased my first arborist throw line, I also purchased this folding throw line packing cube:

It has a huge opening, is stable on the ground, and makes for an incredibly quick deployment and pack-up.

While the cube folds into a compact triangle, it’s a little too bulky for backpacks I use during SOTA and other trailside activations.

A smaller throw line storage bag

A few months ago, I purchased a second throw line for backpacking and this compact Weaver Leather throw line storage bag (note: Amazon affiliate link).

If I’m being honest, I was very skeptical about how easily this bag would work in the field. One of the reasons my throw line storage cube works so well is the opening is large allowing the line to deploy without tangling. Packing up is so fast because the line can be flaked back into the cube in a matter of seconds.

Before purchasing, I was afraid the compact throw line bag might get tangled when being stored in such a small stuff sack. I was really concerned packing the line in the storage bag might take too much time.

I purchased the the throw line bag and a new throw line from Weaver.

At home, I did a full break-in of the new throw line (attaching it to a tree, stretching it to full length, then pulling it for enough tension that some of the bend “memory” is removed). Then I attempted to simply stuff the line in my throw bag–it took ages, because the whole idea of a throw line is that it doesn’t easily tangle. The line wanted to “spring” from the bag as I tried stuffing it in.

A much better way: The “Figure 8” stuffing method

After a field activation this spring, I received a game-changing tip from one of my subscribers and I hope they step up to take credit! (Update: it was NW3S!–thank you!).

When stuffing the line back in the bag, wind it on your hand using the figure 8 method. I wind almost all of my lighter-weight cables and antenna wires in a figure 8 so that they deploy without getting tangled. I’ve been doing this for years and it works brilliantly.

I’d never thought about using this method on the arborist throw line. I was amazed with how effectively it worked.

Video demo

I made a short video (thank you for requesting this, Scott!) to better demonstrate how I pack my throw line storage bag now:

This method works amazingly well and I can usually pack the entire line within one or two minutes.

Again, I’m incredibly grateful to the subscriber who first suggested this method!
