Late-Shift 80 Meter Activation Tonight

9 Comments

I normally don’t announce activations on QRPer, but tonight I plan to activate a two-fer of Pisgah National Forest (K-4510) and Pisgah Game Land (K-6937) starting roughly around the turn of the UTC day (19:00 EST tonight, or 00:00 UTC on Februay 7, 2024).

I’ll be testing an 80 meter coil for the Chelegance MC-750 vertical.

I’m announcing this POTA activation becase a number of you who live way too close for a 40 meter and up contact have asked me to post if I plan a late night activation on 80 meters.

I hope to put you in the logs!

Cheers,

Thomas (K4SWL)

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 →

Major POTA fun with the TEN-TEC R4020 and PackTenna 20M EFHW!

4 Comments

The other day, I was thinking…

If  2014 Thomas looked at 2024 Thomas’ QRP radio inventory, he wouldn’t believe the number of radios he’d accumulated in a mere decade.

It’s a little insane, really.

The thing is, over the years, I’ve picked up some great QRP bargains at local hamfests and via various online classifieds. While it’s not exactly “chump change,” you can often find good used QRP radios for less than $300.

Sometimes it’s hard (for me) to pass up those deals.

One such deal was a local fellow who wanted to sell his Ten-Tec R4020 a few years ago.  He listed it for $125, and there weren’t any takers for a few days. (Keep in mind, this was a wee bit before our current CW Renaissance.)

I contacted him and snapped it up. I thought the R4020 might be a fun little two-band radio for POTA and SOTA adventures.

I was right!

The R4020 is an incredibly fun radio to use in the field.

The audio is superb. It has a low noise floor, great sensitivity, and a well chosen filter width. What the R4020 lacks in features, it makes up for with audio fidelity, in my opinion.

I look forward to each and every activation with this QRP wonder.

Speaking of which…

Tuttle Educational State Forest (K-4861)

On Wednesday, January 3, 2024, I made some time in the afternoon to stop at Tuttle Educational State Forest.

I believe I was on the way back to the QTH that afternoon after an overnight with my folks in Hickory, NC.

I love Tuttle, but it had been a while since I completed an activation here. In the activation video (below) I said it had been a couple of months, but later I checked and realized it had been four months! Wow! Hard for me to believe it had been that long!

That day, the park was void of visitors. I was the only person in the parking lot. No surprise here: kids were just heading back to school after a long Christmas break, so there were no field trips on site.

Since there was no competition in the picnic area, I decided to grab a site I might not have actually used before in previous Tuttle activations. I’m evidently working on my WATPT (Worked All Tuttle Picnic Tables) award!

First, a quick inventory…

Before heading to Hickory the previous day, I grabbed the little Blue Ridge Outdoors pouch that held my R4020 and much of the supplies I’d need to get on the air.

I knew, though, that this wasn’t a fully self-contained field kit. Not yet, at least. I hoped that between my main radio gear pack and what I had in the car, I could piece together an entire station.

In my activation video, I speak to the mental checklist I use to make sure I have all of the necessary components to complete my field kit. I did this on site as I set up (typically, this is done prior to leaving the QTH).

Fortunately, I had everything I needed, including an external speaker.

Side note: Some of you might notice the (disproportionately) large Bioenno battery I used during this activation. Yes, it’s crazy overkill for this wee QRP radio. I’d normally use a 3Ah battery, but frankly, I need to exercise my 15Ah battery from time-to-time, too! It gets the least amount of field time because I normally save it for my QRO radios that I use so little in the field.

On The Air

I’d packed my PackTenna Mini 20 meter EFHW with the R4020.

My 40 meter PackTenna EFHW would have been a better choice–since it would have been resonant on both of the R4020’s bands (20 and 40M)–but at the time of day I was operating, I knew 20 meters would serve me well, so 20 meters it was!

POTA with Jonathan (KM4CFT) at the Zebulon Vance Birthplace (K-6856)

4 Comments

On Thursday, December 28, 2023, I had the good fortune of meeting up with Jonathan (KM4CFT) at the Zebulon Vance Historic Birthplace (K-6856) to play a little POTA.

You might recognize Jonathan’s callsign because he has a popular YouTube channel and also produces excellent EFHW antenna kits.

These days, Jonathan lives in Colorado, but he’s originally from western North Carolina. We met once before when he was in town visiting his folks. That previous time was very short, though; this time, we wanted to meetup and fit in a POTA activation together.

We arranged to meet around 2:00 in the afternoon at the Vance Birthplace.

We decided to deploy one of Jonathan’s End-Fed Half-Wave antennas. He cut this particular one for 20 meters.

We set up under the picnic shelter with the antenna essentially in a sloper configuration.

Gear:

Note: All Amazon, CW Morse, ABR, Chelegance, eBay, and Radioddity links are affiliate/partnerhip links that support QRPer.com at no cost to you.

I brought along a couple of radios that Jonathan had yet to operate. He chose to use the Penntek TR-45L (great choice!).

One wrinkle: Jonathan operates with his paddle in “reverse” with the left paddle sending dashes and the right sending dits.

Unfortunately, the TR-45L doesn’t have a software function to flip between “normal” and “reverse” settings. No problem, though: Jonathan simply turned his key (a BaMaKey TP-III) upside down! Problem solved!

The only annoying issue was the 45L speaker–something inside the chassis or speaker assembly was rattling/buzzing with louder signals and with the sidetone. After noticing the speaker vibration at an activation in South Carolina a few months ago, I opened up the TR-45L at the QTH and tried to tighten down anything that could resonate inside the chassis. My fix seemed to work until we powered it up for Jonathan to use. I may have to add some padding around the speaker assembly if I can’t locate the culprit inside the radio–it could be pretty much anything.

Jonathan plugged along and paid no attention to the buzz, nor my fiddling with the radio while he operated. (You’re a good sport, OM!).

Here’s Jonathan’s QSO Map:

After he completed his activation, Jonathan handed over the radio to me.

Since I couldn’t sort out the acoustic buzz/vibration without opening the radio on the picnic table, I opted to swap out the TR-45L with my Discovery TX-500.

I hopped on the air and logged quite a few stations on 20 meters. It was serious fun!

Here’s my QSO Map:

Activation Video

Here’s our real-time, real-life video of the entire activation.  As with all of my videos, I don’t edit out any parts of the on-air activation time. In addition, I have monetization turned off on YouTube, although that doesn’t stop them from inserting ads before and after my videos.

POTA Meetups

Jonathan, it was great hanging with you and, again, I’m so impressed with your CW progress. It seems like only yesterday when you started your CW journey!

When folks are passing through western NC it can be difficult for our schedules to align for a POTA meetup,  but I’m so happy when they do.

Thank you!

Thank you for joining us on this joint activation!

I hope you enjoyed the field report and ctivation video as much as I enjoyed creating them.

Of course, I’d also like to send a special thanks to those of you who have been supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free, I really appreciate the support.

As I mentioned before, the Patreon platform connected to Vimeo make it possible for me to share videos that are not only 100% ad-free, but also downloadable for offline viewing. The Vimeo account also serves as a third backup for my video files.

Thanks for spending part of your day with me! Have an amazing weekend!

Cheers & 72,

Thomas (K4SWL)

Braving the Polar Vortex at Yuchi WMA

8 Comments

by Teri (KO4WFP)

It has been two and half weeks since the final activation of my winter-break Florida POTA trip. Despite a polar vortex dumping frigid weather into Georgia, I was determined to activate and continue working on my 60 new-to-me park activations goal for 2024.

Google Maps

About an hour and a half from my home QTH is Yuchi Wildlife Management Area (K-3778). The property is managed by the Georgia Department of Wildlife Resources and located next to the Savannah River, the border between the states of Georgia and South Carolina. The site consists mostly of pine uplands and hardwoods with some acreage of openings for wildlife. One can hunt for deer, turkey, small game, and doves as well as utilize the public shooting range located on the property.

Given the time of year, I pulled out my copy of the GA Department of Natural Resources (DNR) Hunting Regulations booklet to see what might be in season right now. Looking at the specific regulations for Yuchi Wildlife Management Area (WMA), only dove season might be an issue while I activated the park. Just to make sure, I contacted the appropriate DNR office and spoke with a helpful employee. He assured me I was not likely run into anyone hunting on a weekday for doves or small game. Of course, Daisy and I would wear blaze orange just to be careful when outside the car.

My time for an activation was tight given my previous commitment as a K3Y/4 operator for the Straight Key Century Club the same afternoon. However, if I got an early enough start, I could make it work.

Daisy and I left the house around 7:30 AM with a quick stop at Lowe’s. I really didn’t want to sit outside in the chilly temperatures; it was 26 degrees according to the weather app. The stop at Lowe’s was to take advantage of an idea generated by a comment from John KK4ITX, an idea I hoped would keep me warm in the car during my activation.

The drive to Yuchi WMA was pleasant. I enjoy driving in rural Georgia. This particular drive went through the towns of Oliver, in which I found another diminutive and cute U.S. Post Office, and Sylvania. Sylvania had that typical small-town feel. I snapped pics of the two murals I saw, something I look for and often find in these communities.

Daisy and I finally arrived at the WMA about one and a half hours after departing Bloomingdale. Before we reached the site, its neighbor, Plant Vogtle, revealed itself.

The plant is a four-unit nuclear power plant managed primarily by Georgia Power. The first two units went online in the late 1980s. Units three and four were the first nuclear units in the United States approved since 2016. Unit Three is operational and Unit Four is supposed to be up and running this year. When all four units are operational, Plant Vogtle will be the largest nuclear power plant in the United States.

Daisy and I found one of the open dirt roads on the property and begin our search for a suitable QTH. Thankfully my Subaru Crosstrek has four-wheel drive as there were soft spots on the road. I wouldn’t want to drive here after a heavy rain.

We drove past plantings of pine as well as areas of hardwoods. After rounding a corner and driving up a slight incline, a wider opening in the canopy appeared. On one side next to a planted pine field, there were several taller deciduous trees now devoid of foliage. It looked to me like a perfect QTH for today’s activation with abundant sunshine.

POTA Postcard Field Report: Finally Snagging a Kilo on the Blue Ridge Parkway (K-3378)

30 Comments

It’s funny: I’ve met POTA activators who’ve been hitting the field for only a couple of months and have already obtained a “Kilo” award for confirming one thousand QSOs from the same Parks on the Air entity. Most of my active POTA friends have multiple Kilos.

Me? Until December 29, 2023, I had never obtained a Kilo at any POTA site!

Something you should know about me: I don’t check my POTA stats or awards frequently…as in maybe once or twice a year–?  I’m the same with my YouTube stats and even website stats. I’m just not a terribly numbers-motivated person.

That said, I fully recognize that numbers give us a snapshot of how and where we activate. Only recently, I checked my awards page to see if I’d ever snagged a Kilo and was surprised to find that no, I had not.

I say “I was surprised” but truth is, my activations tend to be really short. I think my average number of logged hunters per activation is probably 20-25.

I checked the POTA website and I had 48 activations in the books for the Blue Ridge Parkway (K-3378). My total number of contacts confirmed was 994.

Yeah, I was six contacts short of a Kilo. What!?! This needed to be remedied!

So technically…

The KX2 was my NPOTA companion (pictured here at the Carl Sandburg home during NPOTA).

In truth, I probably could have achieved a Kilo much earlier because POTA allows you to submit logs from 2016’s ARRL National Parks On The Air (NPOTA) event. During NPOTA, I activated the Blue Ridge Parkway (guessing here) about 50 times; it was my most accessible NPOTA park and I hit it several times a week. However, I have not submitted my NPOTA logs to POTA, so my POTA numbers do not reflect my NPOTA activities.

Postcard field report

I’m still catching up after a challenging first few weeks of 2024. In fact, since I made that post, so much more has happened. January 2024 has been a tough month.

I’m nearly a month behind on email, so if you’ve written to me with questions, you likely haven’t received a reply. I’ve simply needed a break during this time.

Speaking of busy, I have a pretty hectic day in store, but I’m eager to post one of my field reports (I enjoy this) so we’re going to do it “postcard” style. I’ll let my activation video and logs tell the story of this brilliant little activation on December 29, 2023.

Spoiler alert: I got my Kilo!

The Final Fling in Florida

8 Comments

by Teri (KO4WFP)

It is Sunday, December 31st, the final day of 2023 and, coincidentally, my winter-break Florida POTA trip. Time to return home. But, as I promised at the end of my last article, the journey is not yet done. A POTA Babe is not going to squander the opportunity to fit in another activation or two on the way home.

Google Maps

Joseph and I loaded up the car one final time after our stay at an Airbnb in Umatilla. I found two parks at which to attempt activations – Lake George State Forest (K-4627) and Pellicer Creek State Conservation Area (K-8367). I chose Lake George because I had yet to activate a state forest and Pellicer because of its proximity to Interstate 95, my route back home.

Lake George State Forest is named (unironically) for Lake George, the second largest lake in Florida. The forest is formed from lands previously used for timber, production of naval stores, cattle grazing, and hunting. It consists of over 20,000 acres of land that offer trails for hiking, cycling, and horseback riding as well as access to hunting, fishing, and birding.

I was unclear as to where to easily access Lake George State Forest. We found the Dexter/Mary Farms Tract entrance at which is a checkpoint for hunters. I learned I needed to purchase a pass before accessing the property and could do so via an off-hours phone number. I really didn’t want to set up shop in proximity to hunting, partially because it seemed like a bad idea (duh) but also I didn’t bring my blaze orange vest on the trip.

We learned of another entrance for the forest and headed that direction. Along the way, we ran into the Barberville Yard Art Emporium who billed itself as offering the largest variety of unique handcrafted outdoor art. I believe it judging from what I saw. Anyone for a giant chicken?

After gawking at the sculptures, we headed to the Fawn Road entrance for Lake George State Forest. This entrance looked more like what I expected.

My brother Joseph donned his bright orange rain poncho and headed up the road for a hike. I, on the other hand, looked for a place to set up and get on the air. I’d need to stick to the road as it was flooded on both sides and I didn’t bring the footwear to tromp through water. Most of the trees were very tall pines. I didn’t think I could get a line on their lowest branches.

Thankfully, I found a few trees of lower height. Once the Tufteln EFRW was installed and my station set up in the road (it was closed to vehicular traffic), I commenced my activation.  I ran later than my original estimated start time but the RBN still picked me up.

As usual, I was tight on time. In 30 minutes, I had 20 contacts on 20 meters. Two days ago, I had a contact from Etor F6VMN in France. I figured why not hop onto 17 meters to see if he would hear me again today. Guess what? He did hear me and we logged another contact. The band gave me nine contacts in 10 minutes for a total of 29 contacts at this park.

By this time, Joseph had returned from his hike. We packed up and were off to our next destination – Pellicer Creek State Conservation Area. Continue reading The Final Fling in Florida →

N2YCH: January POTA Travel in Frozen Alaska!

3 Comments

Many thanks to Conrad (N2YCH) who shares the following field report:

Conrad’s January Alaska Activation

By: Conrad Trautmann, N2YCH

“Why would you go to Alaska in January?” is what everyone asked me.

I’ve wanted to see the Northern Lights for as long as I can remember. The best time to see the aurora borealis is between late August to late April in Fairbanks, Alaska. Days are short in January, sunrise is at 10:24am local time and sunset is at 3:38pm. It’s twilight before the sun comes up and after it sets so it’s not pitch dark, but it’s mostly dark for about 19 hours a day in Fairbanks at this time of year. Once I began researching, I learned that peak viewing times for the aurora are between 10p and 2a local time even with the extended darkness. Check aurorasaurus.org for more information.

So, the answer to the question is, “The odds are better to catch the Northern Lights in the winter.”

Cold weather and snow doesn’t bother me having lived in Syracuse, New York for ten years. I have experience with winter weather and driving. Fairbanks is one of the best places in the state to see the aurora since it is directly below the “Aurora Oval” and it has over 100 days a year when the aurora is visible. Except for January 12th through the 15th, 2024, when the sky had 98% cloud cover and it was snowing. Aurora viewing was not happening during my visit.

However, this trip was not a total loss by any means. There are things to see and do here, including activating parks! I activated three parks in three days, Denali National Park (K-0022), Chena River State Recreation Area (K-7228) and Creamer’s Field Wildlife Refuge (K-9697). I’ve heard stories from hams in Alaska that propagation can be spotty, that there can be total radio blackouts from solar flares and that bands we don’t usually worry about in the lower 48, like 20 meters, can be useless at times. I packed enough equipment and antennas to activate on any band from 40 meters to 6 meters, up to 100 watts using my Elecraft KX3 with the Elecraft KXPA100 amplifier. On the first day at Denali, I used the amp for the entire activation, but I realized at the end of the day that Thomas, K4SWL, who runs “QRPer.com” wouldn’t be too happy with a field report from “QROer.com” Conrad, N2YCH. To remedy that, I activated my second park using just my KX3, no amp. At K-7228, my first 11 QSO’s were QRP and the park was officially activated using only QRP power. I activated my third park QRO, read on and I’ll explain why.

[Thomas here: For the record, readers, I gave Conrad a Special Use Permit to mention QRO on QRPer! Ha ha! Of course there’s no problem going QRO from time to time!]

Back to propagation, I emailed one of the most active POTA activators in the area prior to my trip to get a sense of what to expect. I highly recommend doing this for anyone planning to travel somewhere and activate. Look at the POTA pages for the parks you want to activate and you’ll surely see a repeat activator with a Kilo award or many visits to those parks. They know the parks the best and also what to expect for propagation. They also share your passion for POTA and are usually very happy to help. The advice I received was that it would be difficult to make contacts on 20 meters and that watching the MUF (maximum usable frequency) charts would serve me well. (Check out hf.dxview.org) The activator said 10 meters would probably be the best band during daylight hours. He was exactly right. Even with QRO power, 20 meter reception in Alaska was noisy and my signal did not get out very far on FT8 watching the pskreporter.com spot map. I moved to 10 meters and quickly had a steady pile up. I stayed on the air until I depleted a 9ah and a 3ah battery I brought. What fun!

Okay, so for the QRP activation, I was at a trailhead parking area out near the Chena Hot Springs resort. Before the activation, I stopped and did the tour of the Aurora Ice Museum and took a dip in the natural hot springs. I do recommend the hot springs if you ever go to Fairbanks. It was -10F degrees when I was there, quite an experience.

Chena Hot Springs

I intentionally wanted to delay my activation from early morning to closer to sunset to see if operating during the evening gray line passing over would help improve the number of contacts I could get. The short answer is that it was worse…way worse. I went back to activating closer to sunrise on my third day and had similar results as I did the first day, much better. Sunrise wins.

The map above shows my initial ten QRP QSO’s from K-7228.

What really continues to amaze me is just how far my signal can reach with the portable equipment I was using. I brought the Buddipole so I could configure it as a vertical or a dipole. I tried it as a vertical on 20 meters on my first day and as I said, the reception was poor. The beauty of the Buddipole is that I could quickly reconfigure it to a 10 meter dipole. With the tripod, it’s roughly 10’ off the ground. There was no wind to speak of, so I didn’t need to guy it. If there was, I would have used a bungee cord to secure it to the car bumper or side mirror.

It breaks down and fits in the bag I bought with the Buddipole tripod and I tossed it into my checked bag on the plane. With the tripod and mast, it’s just a little too long for the carry-on bag. I could have brought a fiberglass push up mast and wire antennas in my carry-on, but I decided on the checked bag and brought the Buddipole to have as many options as possible. After all, I was traveling all the way to Alaska. Continue reading N2YCH: January POTA Travel in Frozen Alaska! →

More Surprises in Florida

7 Comments

by Teri (KO4WFP)

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!

QSO Map for Green Swamp Wilderness Preserve http://tools.adventureradio.de/analyzer/

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 →

Scott’s Self-Supporting Random Wire Antenna System

Many thanks to Scott (KK4Z) who shares the following post from his blog KK4Z.com:

K4SWL+ Antenna

by Scott (KK4Z)

On a recent post on QRPER.com, Teri KO4WFP was at a park in Florida that did not allow wires (or anything else) in their trees. Many POTA activators use End Fed Half Wave antennas which usually require one end in a tree. While it doesn’t happen at all parks, not being able to hoist your antenna could bust an activation.

I realized this may happen to me even though Georgia appears to be pretty lenient when it comes to such matters, I decided to switch to a park friendly antenna. I have been a fan of QRPER.com for quite some time and occasionally Thomas will repost something from my humble blog. That being said, it was K4SWL that got me started using a random wire antenna. My basis for my antenna was his speaker wire antenna which was a 28.5’ vertical antenna with a 17’ counterpoise. I used it a few times in that configuration and then started to modify it. I call this antenna my K4SWL+.

Some of the differences are I use a push-up pole to get the antenna in the air and at the base I use a 9:1 UnUn and a 1:1 Choke to keep RF out of the radio. A random wire antenna can feed RF back into the coax.

The wire is 14 ga. coated flex weave from The Wireman. This was left over wire from some other antenna projects. When I started this project I was using 22-24 ga. coated wire from SOTABeams but realizing there was no need to save weight, used the heavier wire. This allows me to dual purpose the antenna both for FunComm and EmComm. The insulator at the top is 3D printed with my call-sign and the base is U-type lugs. I find these are the best as I do not have to take the nut off of the antenna studs and if pulled hard will come loose instead of damaging the UnUn. I connect the antenna to the top of the push-up pole with a small Nite-eze “S-biner” size 1.

The 9:1 UnUn comes from Palomar Engineering. I have already created a blog post about how to build it and it can be found here: https://kk4z.com/2022/05/28/91-unun-qro/

Part of this blog post was to bring the different components together into one blog post.

I made two different types but I found the second works much better.

The project is pretty easy, the only caveat is to pay attention to what wire goes where. Putting it all together, you need a push-up pole, a Flag holder and maybe a trailer hitch extender. I will provide links below. The Flag Pole holder I used was not available so the link I used is a probable substitute. I have a trailer hitch on both my truck and my camper, When I pull into a campsite I have a choice of which hitch to use to keep my antenna clear from the trees. With the antenna up, I wrap the antenna wire around the push-up pole from tip to base, to prevent the wire from sagging near the tip. I attach the UnUn and choke to the mast with Stretch Velcro Straps. With my antenna up I have park employees drive by me all day along. Most of the time we exchange a friendly wave and occasionally one will stop by for a chat. I have had zero issues with this antenna at any of the parks I have visited.

How does it play? It has pretty much been a main antenna for just about all of my POTA activations. You can go back through my blog post and see what equipment I used with the antenna and the accompanying QSOMap. You do need an antenna tuner with this antenna and I typically use an LDG Z-11 Pro which I’ve had for 15+ years. The antenna tunes up from 80 to 6 meters and I have run the power as high as 65 watts. I normally run 10-35 watts depending on band conditions. I have tried it on 160 meters and while I can get a match, I don’t think much RF is leaving the antenna. I’ve made a few contact with it on 160. If you like to work 160 meters during a POTA activation, I suggest a Chameleon EmComm II with a 60’ antenna and a 50’ counterpoise. I run it as an inverted L with the apex about 20’ up my push-up pole and the end sloping down to something not a tree. Last time I tied it to the lantern stand at the campsite. It worked pretty well and I was able to make contacts on 160.
