POTA Field Report: Conquering South Mountains State Park with Max!

One of the closest parks to my parents’ home in Hickory, North Carolina (where I travel most weeks) is South Mountains State Park.

Despite its convenient location, I haven’t activated South Mountains many times and, in fact, the times I have activated it, I’ve always found it a struggle to log the ten contacts needed for a valid park activation. I suspect it’s had less to do with the physical location of my operating spot (which has admittedly been in a bit of a “bowl” surrounded by hills) and much more to do with the fact that propagation has been crappy on the days I tried to activate.

Ironically, I’ve activated the adjoining South Mountains Game Land numerous times with wonderful success. It’s funny how that works.

Max (WG4Z) set up the CHA TDL.

I had a good reason to hit South Mountains on September 9, 2021. My buddy Max (WG4Z) had just purchased an Elecraft KX3 at the Shelby Hamfest (at an incredible deal, I might add). He plans to pair it with a Chameleon CHA TDL (Tactical Delta Loop) he has on order.

POTA Field Report: Fort Dobbs, 5 watts, and speaker wire

After making my first activation of Fort Dobbs State Historic Site, I knew I’d be back in short order. It had all of the things I love about a great POTA site: it’s accessible in my weekly travels, has tall trees, a huge shelter, and friendly park rangers. Plus, it’s chock-full of history.

Does it get any better?

Fort Dobbs State Historic Site (K-6839)

On Wednesday, August 25, 2021, I stopped by Fort Dobbs for a quick activation.

Even though I arrived only shortly after the park opened and I was obviously the only guest there, I checked in at the visitor’s center to get permission to do the activation.

Not only did they grant me permission, but they also allowed me to set up in their main covered picnic area.As I mentioned in a previous post, I believe you should always ask permission at small historic sites like Fort Dobbs.  For one thing, I want the staff to know where I am and what I’m doing. Unlike vast state and national parks, their spaces to set up may be more limited and the last thing you’d want to do is set up shop in a space where they plan to do a scheduled outdoor presentation in period costume.

 

In addition, some historic and archaeological sites  may have restrictions on the types of antennas you employ. I’ve known of some, for example, that require fully self-supporting antennas that need no trees nor no stakes in the ground.

The folks at Fort Dobbs couldn’t be more friendly.

On the air

I decided I’d pull out the trusty 28.5′ speaker wire antenna and see how well it might perform while paired with the mAT-705 Plus and Icom IC-705.

Set up took all of three minutes.

With super lightweight antennas like the speaker wire antenna, there is rarely a need to tie off the end of the throw line to hold the antenna in a tree and in position. Unless there are strong winds, the weight of the throw line itself will hold it in place. Deploying the antenna and connecting it to the ATU and transceiver may have taken me two minutes.

Relying on trees can be a little unpredictable; some sites may have trees that are too short, some with branches that are too high, some that are too dense with branches, and/or trees may not be ideally situated for a field activation.  When things aren’t ideal, it might take much longer to deploy a wire antenna in a tree. This is one reason why so many POTA and SOTA ops choose to bring their own collapsible support–it gives them a degree of predictability when setting up at a new site.

Fortunately, at Fort Dobbs, there are numerous trees that are ideally situated for effortless field deployments.

Gear:

I hopped on the 40 meter band and started calling CQ.

Fortunately, propagation was in pretty good shape, and I worked a string of contacts.

It was nice to experience a more “normal” activation where propagation wasn’t completely in the dumps.

I eventually moved up to the 20M band and did a little hunting before finally packing up.

All in all, I made eleven contacts–just one more than the 10 required for a valid POTA activation.

I could have stayed and played radio for a much longer period of time–and I was tempted for sure–but I chose to fit in one more activation that morning at nearby Lake Norman State Park. So I packed up and moved on.

QSO Map

Here’s the QSO map of my contacts at Fort Dobbs:

Video

I made another real-time, real-life, no-edit video of the entire activation as well. You can view it via the embedded player below, or on YouTube:

I didn’t work any DX at Fort Dobbs, but I was super pleased with the speaker wire’s performance using only 5 watts of output power. I imagine if I would have stayed on the air for another hour or two, I could have worked a couple stations in Europe. It was a tad early for much activity on 20 meters.

Thank you!

Thank you for reading this field report and a special thanks to those of you who are supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement–my content is always free–I really appreciate the support.

If you can, find some time to chase or activate a park or summit near you! Or, if you have an opportunity, just take your radio outdoors, hop on the air, and have some fun. It’s good for your soul!

And a friendly reminder: you don’t need a fancy radio or fancy antenna. Use what you’ve got. Pretty much any transceiver you’re willing to lug to the field will work. And antennas? As you can see, even $4 of speaker wire conjures up some serious QRP magic!

Cheers & 73,

Activating Pilot Mountain State Park on a beautiful summer afternoon

After a successful SOTA and POTA activation at Hanging Rock State Park on Tuesday, July 13, 2021, I drove to nearby Pilot Mountain State Park. It was quite warm, but a beautiful day with no afternoon thunderstorms in sight.

I couldn’t pass up the opportunity to play a little more radio. As the French say, “Il faut en profiter!

Although I’ve seen Pilot Mountain numerous times in my travels, I had never actually visited the park so this was a new-to-me park activation.

Pilot mountain is a landmark in the Yadkin river valley and has a fascinating back story.

Per Pilot Mountain State Park’s website:

“Pilot Mountain is a remnant of the ancient Sauratown Mountains. A quartzite monadnock, this rugged mountain rock has survived for millions of years while the elements have eroded surrounding peaks to a rolling plain.

Pilot Mountain is capped by two prominent pinnacles. Big Pinnacle, with walls of bare rock and a rounded top covered by vegetation, rises 1,400 feet above the valley floor, the knob jutting skyward more than 200 feet from its base. Big Pinnacle is connected to Little Pinnacle by a narrow saddle.

The mountain was mapped in 1751 by Joshua Fry and Peter Jefferson, father of President Thomas Jefferson. Pilot Mountain became North Carolina’s 14th state park in 1968. The Pilot Mountain Preservation and Park Committee proposed the establishment of Pilot Mountain as a state park in order to protect it and the surrounding area from commercial development. The group secured options on the land and raised matching funds that made it possible to purchase with
federal grants.”

Pilot Mountain is a SOTA summit, but it has never been activated because it would require an experienced rock climber (assuming access is even allowed). The base of Big Pinnacle is 61 meters above the summit trail system, so well outside the 25 meter activation zone.

Pilot Mountain State Park (K-2750)

I only had my sights set on making a park activation out of Pilot Mountain and, frankly, I didn’t even have time to explore the trail system  that Tuesday.

Finding a spot to set up was quite easy. I entered the park and took a right at the roundabout which lead to the parking area at the top portion of the mountain.

From there, I found a small picnic area perhaps 50 meters from the parking lot. I carried my gear there and set up shop!

Since I was doing this activation mid-afternoon, I had the picnic area to myself, save one unfortunate woman who was trying to (conspicuously, if I’m being honest) fit in a bit of meditation time.  She picked out a picnic table near one of the main trails basically in the center of the picnic site , so I assumed she was pretty good at blocking out noises you’d normally hear at a busy park.

But the question remained: could she block out the sweet sound of CW emanating from my FT-817?

There was only one way to find out!

In truth, I try to lay low at parks and not disturb other people. In this case, I picked a table on the perimeter of the picnic area but it was still only a couple tables away from her. Since I was making one of my real-time, real-life field activation videos, I would be using the speaker–instead of headphones–with the FT-817.

In other words, there was no escaping a little CW music!

I shared my picnic table with this little Praying Mantis
I think he’s upset that my throw line is all over *his* ground.

Gear:

This was also the first time I’d used my new orange single-level CW Morse paddle very kindly gifted to me by contributor/subscriber, Nathan (N8HWV).

Although it might look like a dual lever paddle, it’s actually a single lever!

Thank you so much, Nathan! 

On The Air

I started on 20 meters CW and, fortunately, it was hopping!

I worked 18 stations in 19 minutes. Whew!

Many thanks to N2EIM and NA9M for the P2P (Park To Park) contacts!

I then moved to 40 meters where I worked K8DRT for a second time (first was on 20M) and my “it wasn’t a real activation unless I worked him” buddy, K8RAT.

40 meters wasn’t in as good of shape as 20 meters was.

Having no way to spot myself to the POTA site, I didn’t attempt any SSB contacts–I would have at least for a while,  otherwise.

Video

Here’s a real-time, real-life, no-edit, no-ad video of the entire activation:

Inner Peace through code…

Evidently, Morse code must have “resonated” with my meditating neighbor.

She didn’t move until I I was off the air–as if the conclusion of her session coincided with the end of my activation.

Obviously, a little CW helped her along her journey to inner peace. 🙂

I know it did for me!

Thank you

As always, thank you for reading this field report. I hope you take a little time to achieve your inner peace by playing radio outdoors! 🙂

Activating Anderson Mountain: My first drive-up one point summit

As AA6XA wrote on his blog:

To quote the W4C association manager Pat, KI4SVM, “Anderson is a drive-up with no other redeeming qualities.” This perfectly describes the mountain. It is easy to get to, at the top of Tower Road, right off of Route 16. The road to the top get a bit rough in places, but is passable in any car.

He had me at “no other redeeming qualities”–!

I must admit that all of the summits I’ve activated so far have been pretty amazing: offering up spectacular views, wildlife, and wonderful hiking opportunities. All of them were also on protected public lands like state/national/county parks.

Anderson Mountain (W4C/WP-012)

Earlier this year, I made a spreadsheet of summits I planned to activate. Anderson Mountain was one of them because of its convenient location in my travels to visit family each week. I had also been saving it for the day that I planned to activate a nearby park–Tuesday, July 6, 2021 was that day!

Earlier, I had an amazing activation at Mountain Island Educational State Forest using the Yaesu FT-817ND, T1, and my speaker wire antenna. I completed Mountain Island in enough time I could also pop by Anderson Mountain for a quick activation.  It was literally a six minute detour from my route, if that.

The mountain is directly off of US 16–the main highway between Newton/Conover and Charlotte.

You turn off of the highway onto a dead end road that leads to the summit. About halfway up, it turns into a single lane privately-maintained road that, as AA6XA noted above, is rough but passable in any car (well, save a Lamborghini but I’m guessing most SOTA ops don’t own one of those!).

The road to the summit is a straight–there’re no confusing forks in the road and it’s impossible to get lost.

Once on top, you’re greeted by a few clusters of communications towers. This is actually pretty common sight with smaller one point summits because they typically have superb line-of-sight to populated areas and are easily accessible by vehicle.

When you look around, you can understand why Pat would say it has no redeeming qualities: towers, rusty transmitter buildings, razor wire on chain link fences, and litter all over the place.

Not the sort of spot that would inspire Ansel Adams.

Judgement call

It’s worth noting here that, unlike POTA, you’re not allowed to operate from a vehicle during a SOTA activation–even at a “drive-up” summit. There’s no such thing as a mobile SOTA activation.

Indeed, you’re not supposed to operate in “the vicinity” of your vehicle either (although, there’s no distance noted and I’m guessing this is on purpose to allow leeway and the op to make a judgement call).

I set up in a little island of trees in the middle of a road loop on the summit. While I wouldn’t call it a hike, I did walk the entire summit after arriving to check for other operating spots, but decided to set up near where I parked the car. In fact, it’s really the only safe spot I noted in the activation zone to park since the road is single lane and you would otherwise block access to one of the transmitter sites. I thought about parking further down the road next to one of the transmitter fences, but I felt like that would have been on private property.

Side note: SOTA forbids operators from trespassing on private property without the owner’s permission. I checked the road very carefully for “no trespassing” signs, but the only ones I found were to keep people out of and away from the fenced-in transmitter sites.

I also thought about trying to operate in a spot on that little island where I couldn’t see my car as easily in the cluster of trees–to remove myself from the “vicinity” of the car–but that would have been awkward, too and only separated me an additional 10-15 meters or so. I chose the option where others could see me and I could see them if, for example, a Duke Energy service vehicle approached.

I was fully outside of my car, though, and not using it to support my antenna or any equipment–another important factor.

Sometimes as an operator you have to make a judgement call when you arrive at a site to stay within the rules and the spirit of the program. I’ve never had a SOTA or POTA activation where I felt I was splitting hairs until this one. I decided that this was the best scenario to activate Anderson Mountain in a way that wouldn’t inconvenience other property owners, nor cause suspicion that might lead to a future no trespassing sign on the road. It was the safest set up and I’m willing to bet most previous activators did exactly the same thing. I felt it was within the spirit of the program.

Now where was I–? Oh yes…

Gear:

On The Air

Since I used the speaker wire antenna at Mountain Island, I used it on Anderson Mountain as well. I deployed the entire station within 5 minutes max: herein lies the advantage of using an arborist throw line, a shack-in-a-box transceiver like the KX2, and a simple wire antenna.

I first hopped on 20 meters CW, spotted myself to the SOTA network (mobile phone reception was superb, by the way) and started calling CQ SOTA.

Within three minutes I logged K6YK, KT5X, W5GDW, and K0LAF which already validated this SOTA activation.

Wow–validating this activation was, as my daughters used to say, “easy peasy lemon squeezy.” 🙂

I added WB6POT and N0RZ for a total of six stations on 20 meters within five minutes.

I then moved to 40 meters SSB and worked K8RAT, W4NA, and WN4AT all within about three minutes.

Finally, I moved up to the 17 meter band and worked F4WBN (our well-known French SOTA chaser) and K2LT.

Packing up my gear was as quick as setting it up.

Video

I did make one of my real-time, real-life videos of the entire Anderson Mountain activation with no edits. If you need a cure for insomnia, I encourage you to watch or listen to it:

At least one redeeming quality…

I mention in the video that some readers and subscribers have confessed that they feel SOTA is less accessible to them than POTA or WWFF.  I would have to agree that summit activations are much less accessible than park activations.

For one thing, there are flat regions on our planet that lack prominences that qualify for the SOTA program. If you live in the middle of a prairie state, you may have to drive a great distance to reach the closest qualifying summit (although you might have a number of POTA and WWFF parks nearby).

In addition, summit activating generally involves hiking–which is actually the motivating factor for many of us (certainly for me as I love hiking).

Some would-be SOTA activators have mobility issues, however, and simply can’t hike great distances with gear on their backs.

This is where “drive-up” summits like Anderson Mountain come in: they’re much more accessible for those with health considerations.

If you live in an area with SOTA summits, but haven’t attempted an activation because you can’t do strenuous hikes, connect with local SOTA activators and ask for a list of “drive-up” summits. There are many of these around–some, like Anderson, are accessible because there are radio towers on top, other are accessible because they’re on a park with accessible vistas, or some are even in a mountaintop neighborhood.

943 Miles Per Watt with the Yeasu FT-817ND, Elecraft T1, and 28.5 feet of speaker wire

When it comes to parks, I haven’t picked up many new-to-me “uniques” lately.

In truth, though, I’ve put more effort into activating unique summits which takes more time to plan, plot, and activate. SOTA has taken a bite out of my park uniques, but I’m good with that because to me it’s less about my park/summit numbers and more about the exploration and outdoor radio time.

On Tuesday (July 6, 2021) however, I added one more unique to my 2021 park count: Mountain Island Educational State Forest (K-4858).

This park is actually a modest detour during my weekly travels, but I’ve never popped by for an activation. You see, unlike other state parks I visit, Mountain Island isn’t yet open to the public on a daily basis. On their website, they state that visits must be arranged in advance, so I reached out to them the morning of July 6 and they promptly replied, welcoming me for a visit and activation that very same day!

Off the beaten path

Since this state park isn’t yet open to the public, I didn’t see the typical brown highway signs pointing me to the park entrance, but Google Maps steered me right to the front gate where there’s a sign.

The gates were unlocked and open, so I pulled into the property and met with two of the park staff who were incredibly kind and accommodating. They were both familiar with the Parks On The Air (POTA) program which made it much easier for me to ask about spots where I could set up my station.

First, though, I wanted to know more about Mountain Island Educational State Forest so I asked ranger Laura about the history of the site.

Turns out, Mountain Island is the newest Educational State Forest in North Carolina and has been in the works for more than 20 years.

The Forest is a vast conservation area that protects 12 miles of shoreline on Mountain Island Lake in the Catawba River Basin. This lake is the primary drinking water supply area for Charlotte, Mecklenburg and Gaston Counties. She told me that one in 23 North Carolinians rely on this area for their source of water.

Much of the land was originally owned by Duke Power who put it up for sale in 1998. Conservation groups purchased the land from Duke’s real estate agency in 1998 and put it into a conservation easement. The land is actually in two counties (Gaston and Lincoln) and a portion in the city limits of Gastonia.

The NC Forest Service now manages the forest and supports the public-private partnership with the counties, municipalities, and conservation groups.

Mountain Island has been actively educating school groups and the public about the river basin and local flora/fauna for many years by appointment. Currently, a new education center is being built on the property and will soon be open to the public with regular business hours. Being so close to population centers, I imagine they’ll stay busy!

Shade

Park ranger Laura was kind enough to allow me to set up under a huge tree in front of their ranger station.

I was grateful for the shade: it was 92F (33.3C) and humid.

There were no picnic tables under the tree, but I happened to have two folding chairs in my car. I used one as a table and the other as a chair. I flipped over my GoRuck GR1 backpack to make a stable base for the Yaesu FT-817ND.

Gear list:

On The Air

I was super pleased to put the Yaesu FT-817ND back on the air. It’s been a while since I’d used it in the field because my review radios (TX-500, X5105, etc.) have taken priority.

I love the FT-817ND and believe it’s actually an exceptional transceiver for CW and SSB ops. The CW full break-in QSK is wonderful and I actually like the mechanical sound of the T/R relay switching (if you like pin diode switching, you should look the other way, though!). With the 500Hz CW filter installed, the front end is pretty bullet-proof, too!

This was the first time I had paired the FT-817ND with my 28.5 foot speaker wire antenna. The random wire antenna needs a good ATU to match impedance, so I employed the Elecraft T1 this time (soon I’ll also try the LDG Z-100A).

I had planned to do a little SSB work, but quickly realized I’d forgotten the FT-817ND microphone. A shame because this site actually has excellent mobile phone service so I could have spotted myself to the network. Next time–!

I started on 40 meters CW and worked ten stations in 21 minutes. That’s a perfect pace for me!

Next, I moved to 20 meters where I worked six more in 9 minutes.

I was incredibly pleased with how well the speaker wire antenna performed–especially on 20 meters.

From the Piedmont of North Carolina, I worked Montana, Texas, New Hampshire, and Italy with 5 watts into $4 worth of speaker wire.

I did a quick back-of-the-envelop calculation and discovered that I yielded about 943 miles per watt!

To be clear, IK4IDF did all of the heavy lifting in our contact with his 9 element Yagi, but still it’s awfully exciting to put DX in the logs with only fair propagation.

Video

Of course, I made a real-time, real-life video of the entire activation (save the set-up and take-down):

Onward and upward!

I packed up quickly because I had a SOTA activation planned that afternoon on Anderson Mountain. I’ll post a field report and video of that activation soon.

Rev 4 FT-817 Buddy Board

Also, I’m about to start soldering together G7UHN’s new Rev 4 FT-817 Buddy Board! Revision 2 worked wonderfully, but revision 4 now includes a CW memory keyer among other upgrades! (Woo hoo!)  All of the components are now in the shack–just a matter of soldering them together and programing the Arduino Nano. Andy, if you’re reading this, expect a call from me soon, OM!

Field Report: Let’s build a super simple antenna on-site and activate this park!

Until 2016, I had never purchased a commercial field antenna; I built all the ones I had ever used.

These days, I take a number of commercial antennas to the field and use them in my real-time videos and I really enjoy deploying and using them. My buddy Eric (WD8RIF) reminded me, though, that I hadn’t actually used a homebrew antenna in ages. He was right!

You see, while I believe commercial field antennas can be incredibly durable and compact, it’s important to note that antennas are one of the easiest components of an amateur radio system to build yourself. They require only the most simple of tools and are very affordable. And the best part? They can perform as well as those that are available commercially.

I also get a great deal of pleasure out of building things.

A simple goal

I’ve mentioned in previous posts that I often set a little goal that runs in the back of my mind for each park or summit activation I make.

On Monday, June 14, 2021, I made a simple goal: buy my antenna wire en route to Lake James State Park, build the antenna on site, and complete a valid Parks On The Air (POTA) activation.

A very simple antenna

I also decided to employ my Xiegu X5105 since 1.) it’s one of the most affordable general coverage QRP transceivers I own and 2.) it has a built-in antenna tuner (ATU).

One of the cool things about having an ATU is that, if it has the matching range, you can allow it to do the “heavy lifting” in terms of matching impedance.

Although I’d never put the X5105 to the test, I suspected its internal ATU would have the matching range to forgo building a 4:1 or 9:1 transformer and simply pair it directly with a random wire.

All I would need was a 28.5 foot length of wire for a radiator, at least a 17 foot length for a counterpoise, and a BNC to binding post adapter.

The antenna would benefit from multiple 17′ counterpoises, but I really wanted to keep this setup dead simple to prove that anyone can build an effective field antenna with a very minimum amount of components.

Even though I have plenty of wire lying around the house to build this simple antenna, I wanted to pretend I had none to prove that any wire would work.

And to add just a wee bit more challenge, I also limited myself to shopping for antenna wire between my home and the park without making a serious detour from my route. That really limited my options because there isn’t much in terms of commercial areas between me and Lake James State Park.

The wire

As I left the QTH, I decided that the best spot to shop was a Walmart in Marion, NC. It would only be a four minute round-trip detour at most.  I had a hunch that Walmart would even have speaker wire which would be ideal for this application.

In my head, I imagined I would have at least three or four choices in speaker wire (various gauges and lengths), but turns out I had a difficult time finding some at Walmart. We live in such a Bluetooth world, I suppose there isn’t much demand for it these days. A store associate helped me find the only speaker wire they had which was basically a 100 foot roll of the “premium” stuff for $17 US.

While I would like to have paid a fraction of that, in the end it’s not a bad price because once you separate the two conductors, you have double the amount of wire: 200 feet.

Although the frugal guy in me cringed, I bit the bullet and purchased their speaker wire. To be clear, though, I could have found another source of wire in that Walmart, but I preferred speaker wire for this application. And $17 to (hopefully!) prove a point? That’s a deal! 🙂

Lake James State Park (K-2739)

Once I arrived on site, I found a picnic site I’d used before with some tall trees around it.

Here’s how I prepared the antenna:

First, I cut 28.5 feet of the speaker wire from the roll and split the paired wires so that I’d have two full 28.5 foot lengths.

Next, I stripped the ends of the wire and attached banana jacks I found in my junk drawer. Although these aren’t necessary as the binding post adapter can pair directly with the wire, I though it might make for a cleaner install. In the end, though, I wasn’t pleased with the connection to the radiator, so dispensed with one of the banana jacks on site, and later dispensed with the other one as well. The connection is actually stronger without the banana jacks.

I then deployed the 28.5 radiator with my arborist throw line, and laid the other 28.5 half on the ground (the ground of this antenna would pair with the black binding post, the radiator with the red post).  I only needed 17 feet of counterpoise, but once it couples with the ground, I don’t think any extra length makes a difference (although less than 17 feet likely would).

The antenna was essentially set up as a vertical random wire with one counterpoise.

I then plugged the BNC binding post adapter into the rig, hit the ATU button, and was on the air.

It’s that simple!

My new speaker wire antenna in all its glory.

Gear:

On The Air

I’ll admit: I was a bit nervous putting this antenna on the air. Although I felt the X5105 ATU *should* match this antenna, I had no idea if it actually would.

Fortunately? It did.

At this point, if you don’t want any spoilers, I suggest you watch my real-time, real-life, no-edit, no-ad, video of the entire activation (including buying and building the antenna!).

Click here to watch the video.

Otherwise, scroll for my activation summary…

I was very pleased that the X5105 found a match on the 40 meter band.

I started calling CQ in CW and validated my activation by logging 10 stations in 13 minutes.

Honestly: it doesn’t get much better than this.

I logged three more stations on 40 meters CW, then moved up to the 30 meter band where the X5105 easily found a match.

I worked one station on 30 meters before heading back down to the 40 meter band to do a little SSB. I logged three SSB stations in five minutes.

Mission accomplished!

In the end, I logged a total of 17 stations including a P2P with K4NYM.

Not bad at all for speaker wire!

After the activation, I tested the X5105 ATU by trying to find matches on other bands–I was able to find great matches from 60 meters to 6 meters. Most impressive!

X5105 battery

You might recall that I attempted to deplete my X5105 internal battery at my last (rather long) activation of Lake Norman State Park.  I wasn’t able to deplete the battery at that activation, but I finally did at this one.

All I can say is that I’m incredibly impressed with the X5105 internal battery.  This was my fourth activation from one initial charge on May 16.  The battery lasted for 20 minutes, taking me well beyond the 10 contacts needed to validate this park. I’ll now consider taking the X5105 on a multiple SOTA summit run!

Short Hike

Even thought the heat was intense and the humidity even more intense, I decided to take in a 2 mile hike post-activation. I snapped a few shots along the way.

This is the Christmas Fern which derives its name from a few characteristics: its resilience to early season snows maintaining a dark green color beyond Christmas, and because folks believe its leaves are shaped like Santa’s boots or even Santa on his sleigh.

Improvements

I’ll plan to add more counterpoises to the speaker wire antenna as I know this will only help efficiency.

In addition, I’ll plan to build even more antennas with this roll of speaker wire. If you have some suggestions, feel free to comment!

Thank you for reading this field report!

Cheers,
