Tuesday last week (December 8, 2020), I was still on a much-needed weeklong vacation near Charleston, South Carolina with my family. We had the day wide-open to enjoy the outdoors and my wife suggested we find a nice park where I could play radio and we could enjoy a picnic.
I looked on the POTA map and chose the Bonneau Ferry Wildlife Management Area (K-3888) primarily because I thought it would be fun to spend some time near a lake.
The drive there was over an hour from where we were staying on John’s Island, but well worth it!
Turns out, it was pretty chilly and windy that day due to a front that had moved through the area during the night. After exploring the area a bit, my wife and daughters decided to enjoy their picnic in the car while I did the activation!
On the air
The spot we found near one of the lakes was ideal for a POTA activation. Although there were numerous large trees that were perfect for wire antennas, I deployed my CHA Emcomm Lite vertical knowing it would also perform well (and it did!)
Because the CHA MPAS Lite is so easy to deploy, I was on the air in a matter of minutes. I decided to stake it in the ground next to the water about 50 feet from my operating position under a tree. You can see it in the photo above (it’s rather stealthy!).
I’m not at all bothered by cold weather, but it was windy enough that my hands did get cold.
I started calling CQ around 17:55 UTC and by 18:34 I had logged a total of 21 stations on both 40 and 30 meters.
POTA hunters will often thank me for activating a park. I always tell them “it’s my pleasure.” Because it is! Just check out the view from my shack!
This is why I love POTA and SOTA so much. I’m a firm believer that radios and their operators are meant to be outdoors!
When I operate outdoors, I tune out everything else in the world and just enjoy the radio time and the outdoors. It’s bliss.
I kept my total time on site less than one hour so my family and I could continue exploring the area and even get a long walk on the beach before sunset.
Here’s a map of the stations I worked with 5-10 watts. Since I discovered this park had never been activated in CW, I made it a CW-only activation:
If you find yourself in the Charleston, SC area, I highly recommend a trip to Bonneau Ferry WMA for some Parks On The Air fun!
One of the great things about Parks On The Air (POTA) is it provides a brilliant excuse to discover public lands that might otherwise go unnoticed while on vacation.
I’m currently taking a little vacation time with the family on the coast of South Carolina and Saturday, December 5, 2020, we decided to explore a nearby park and activate it. I happened upon the ACE Basin Project on the POTA website and thought it sounded intriguing. Our plan was to go to the park, perform a quick activation, perhaps hike a bit, then go to the coast for a beach walk.
I’ve been to wildlife management areas and game lands that have been very basic perhaps only featuring a parking area and a trail or two– which is fine, frankly.
But sometimes you happen upon gems like the Ernest F. Hollings ACE Basin National Wildlife Refuge that are so much more!
Let’s activate!
The visitor’s center and the main gates to the house were closed, but the grounds were still open to the public. We parked in the area just outside the main gates.
Since I had no idea what to expect on site, I grabbed my Red Oxx Micro Manager field kit that had the Elecraft KX2 and AX1 antenna packed inside.
On this vacation, space in the family car was extremely limited, so I only packed the AX1 and the Chameleon CHA MPAS Lite vertical antennas to pair with the KX2. I left the CHA MPAS Lite vertical in the car assuming I might actually perform the activation back at the parking area once we walked around the main house.
The KX2/AX1 travel kit is incredibly portable and lightweight. That’s the whole kit in the bag in the photo above.
On the air
Turns out, we pretty much had the entire campus to ourselves that day and, as a bonus, there was even an excellent picnic area where I could easily set up the KX2 and AX1 antenna.
I hopped on the air around noon and started calling CQ. I had no internet access on site, but could tell the Reverse Beacon Network and POTA spots page had auto-spotted me because I worked about three stations on CW within the first few minutes.
I started on 40 meters CW, but quickly moved over to phone before converting the AX1 antenna for 20 and 17 meters.
A friend spotted me on the POTA site and I worked a couple more stations on SSB.
After only 15 or 20 minutes on the air, my wife suggested we stay put for a couple of hours. We were all loving the gorgeous weather, wildlife, and beautiful scenery by the pond. She asked our daughters to hike back to the car and grab our picnic lunch. I decided to accompany them and grab the CHA MPAS Lite vertical knowing it would be a much more effective antenna for a longer activation.
The hike was about 30 minutes round-trip (that’s a long plantation driveway!).
After I got back to the site, I installed the MPAS Lite which took all of four minutes. A friend, once again, spotted me on the POTA network and I started calling CQ on 20 meters phone.
I quickly worked stations from Texas, Missouri, Indiana, Massachusetts, New Hampshire, and Ontario.
I wanted to hop back to CW mode though, because I discovered K-0520 (this park) had never been activated in CW before and wanted to give CW hunters a chance to put it in the logs.
I worked stations across the US on 20 meters CW from Tennessee to Kansas, from Arizona, to Alaska, and from Iowa to Ontario. Major fun!
I also decided to head further up the band and work AD1C in Colorado on 15 meters (there were no takers on 12 and 10 meters, but I tried–!).
I started around 17:00 UTC and wrapped things up around 19:15 UTC with 34 logged. That may seem like a low QSO count for over two hours, but a good 45-50 minutes of that time I was off air while hiking back to the car and grabbing the MPAS Lite, setting it up, and enjoying a quick picnic with the family.
All in all it was a very memorable day at the ACE Basic WMA. If you’re ever in the low country of South Carolina, I highly recommend a visit. It’s a stunning site with lots of flora, fauna, hikes, and, of course, a great spot for a little field radio fun!
Note: If I worked you during this activation, it may not show up on the POTA website until I’m home from vacation and can create an ADIF file to submit the logs!
On Sunday, November 29, 2020, I decided to return to one of my family’s favorite local POTA sites: the Zebulon B. Vance Birthplace.
On Field Day 2020, I activated this park and learned later that it was an ATNO (All-Time New One). It was very hard to believe because the site is nearly ideal for a POTA activation.
The Vance Birthplace is my go-to site when I want to do some field radio work without travelling too far and when the weather is marginal. The site has a wonderful large covered picnic area we typically have all to ourselves, and I can set up knowing that if it rains it won’t stop the activation.
When we arrived at the Vance Birthplace on Sunday, November 29, we were the only guests at the park. Even though the visitor’s center is closed on Sundays, the park is still open to the public.
On this particular activation, I decided to give my Elecraft KX3 some field time. I think this was its first field outing in several months. I decided to pair it with the Chameleon Emcomm III Portable antenna to make the most of multi-band operation. I knew in advance that this activation would also coincide with the CQ Worldwide CW contest and I wanted some frequency agility–the Emcomm III Portable covers 160-6 with a good ATU.
On the Air
After deploying the CHA Emcomm III Portable random wire antenna in a similar configuration as I have in the past (see image above), I tuned to 17M CW to avoid the contest crowd.
I worked a few stations but, frankly, it was slow going. For POTA, I’ve found that 18 meters isn’t the most productive band at this point in the solar cycle, but a number of other POTA ops were there too as they didn’t want to compete with blowtorch contest stations on 40 and 20 meters.
I eventually moved down to 30 meters and worked a few station as well.
I knew in advance I’d want to log some stations in SSB, so I brought the Heil Proset-K2 Boom Headset along for the ride. I can’t recommend this boom headset enough if you own an Elecraft KX3 or KX2. I believe great audio is the best way to maximize your QRP SSB signal and this headset is custom made for Elecraft gear and certainly delivers. It’s a major upgrade over the KX3 hand mic and, I believe, must add two S units to your signal.
Pileups!
Holy cow! I had no idea what would be awaiting me on 40 meters phone.
I spotted myself on the POTA network and my daughter, Geneva (K4TLI), moved in to log for me on my Microsoft Surface Go tablet.
In all of my field activations, I’ve never had the pileups I had that day. It sounded like proper DXpedition pileups. In order to make the most of it, I had to note three or four calls at a time and work them in succession.
Had this not been POTA, I think I would have moved to split operation to break apart the pileup and work it more efficiently. But in truth, POTA hunters/chasers are not used to thinking in terms of split. With only a handful of exceptions (for example, when I activated rare parks during the 2016 NPOTA program) I’ve never had a pileup so large I considered operating split at a park.
I did work stations about as quickly as I could but didn’t go into full “contest” mode where I give a quick signal report then move on to the next person.
Frankly, POTA and SOTA are not contests and part of the fun of it for me is the community and bonds that are formed between activators and hunters. It’s like meeting people at an on-air family reunion.
My SSB exchanges are never long-winded. I do maintain a certain cadence and keep POTA exchanges relatively brief because that’s just my operating style. I see this as a courtesy to the hunters who may have a limited opening to work my park and I want them to have ample opportunity to put me in the logs. I only spend a bit of time rag-chewing if the bands are a bit dead.
At the same time, I endeavor to make my exchanges friendly. I always try to take a few seconds to thank the operator at the other end of the ether and and wish them a good day.
Because, at the end of the day? POTA is not a contest.
But I digress…
It was amazing fun getting a bit of that pileup “rush”–!
Geneva was logging about as quickly as she could as she heard me reply to stations with their callsigns. I would like to have used the speaker on my KX3 so she could follow the pileup but one of the weak points of the KX3 is the mediocre audio from the internal speaker.
You might see me logging in the photos above because I was also keeping a paper log to cross-reference with the N3FJP generated logs later.
Tally
I worked a total of 90 stations in about one hour and five minutes on the air.
I made 10 CW contacts on 17 and 30 meters, and 80 SSB contacts on 40 meters.
Of course, it was SSB where I really racked up the contacts in short order: 80 stations in 47 minutes. Whew!
I’m certain I could have logged 150-200 stations if I had more than about an hour or so of on-air time. By the time I left the air, I did eliminate the pileup.
Here’s the QSO Map from my logs (click to enlarge):
By the way: Geneva (K4TLI) is close to taking her General exam so you’ll soon be seeing her call on the POTA and SOTA spots page! I’m already piecing together components for her field pack! Of course, she’ll start by building her own resonant antennas! She can’t wait.
A few weeks ago, I posted a report about doing my first park activation with the Elecraft AX1 super compact antenna. If anything, I felt the activation almost went *too* well using such a small antenna. I didn’t want to give others the impression this is all the antenna you’ll ever need–it’s just a brilliant compact antenna designed for convenience and accessibility. It’s a fun field companion and can be used pretty much anywhere.
Yesterday morning, I had a number of errands to run on the south side of Asheville and had not planned to do a POTA activation. While I was waiting on a curbside delivery, however, I was admiring the nice weather and thinking that I might venture out later in the day to do a Parks On The Air (POTA) activation. Part of me knew, though, that if I returned home, I’d get involved with projects and never make it back out to the field.
I always carry a transceiver and antenna in my car, so I opened the trunk and found my Elecraft KX2 transceiver field kit which included the Elecraft AX1 antenna. Technically, that’s a whole station! Why not give it a go–? I’m always up for a challenge.
Since I would be passing by the Blue Ridge Parkway on the way home, I quickly scheduled an activation on the POTA website via my phone so that the spotting system would know to grab my information from the Reverse Beacon Network (RBN) when I started calling CQ.
Blue Ridge Parkway (K-3378)
I knew this might not be an “easy” activation: I would be using a super compact field antenna that’s quite a compromise in terms of performance, propagation wasn’t exactly stellar, and I was activating a popular (hence somewhat stagnant) park on a Monday morning. Not necessarily ideal ingredients for a successful activation.
I also discovered my phone tripod in the trunk of the car, so decided to make one of my real-time, real-life, no edit videos of the entire successful or failed activation. (Hint: It turned out to be a success.)
If you’d like to accompany me on this park activation, check out my video on YouTube:
At the end of the day, the AX1 continues to impress me. It is a compromise? Yes. Does it perform as well as a resonant wire antenna? No. Can it activate a park as well as my other antennas? Yes.
AX1 QSO Map
No doubt, part of my success with the AX1 is because I’m primarily using CW instead of SSB to complete activations. I’ve made SSB contacts with the AX1, but I’ve never completed full park activations with it yet–in truth, though, I’ve never tried.
In fact, perhaps it’s just a lucky streak, but so far the AX1 has been as effective as many of my wire antennas in terms of simply completing valid park activations in less than an hour. My signal reports aren’t as strong as they would be with, say, my EFT-MTR resonant antenna or Emcomm III Portable random wire antenna, but it’s enough to get the job done.
If nothing else, I’ll admit that the AX1 reminds me of the magic of low-power radio each time I use it. When I log stations hundreds of miles away, with such a modest station, I feel like I’ve accomplished something.
In short? It’s fun to use.
Black Friday Sale
FYI: I just received Elecraft’s latest Black Friday 2020 ad and noticed that the AX1 antenna package (which doesn’t include the 40M extension) is on sale. Click here to check it out.
On Tuesday (Nov 17, 2020), I decided to activate South Mountains State Park (K-2753) for the Parks On The Air (POTA) program. As with my activation at Lake James the day before, it was impromptu. Basically, the weather was beautiful, so I couldn’t resist.
In fact, the weather was so nice, on my way to South Mountains I passed by Bakers Mountain County Park and hiked their full trail including the summit. While on that hike, I ran into Kenneth (W4KAC) who had just activated Bakers Mountain for Summits On The Air (SOTA). This was a bit of serendipity because I, too, plan to activate Baker’s Mountain for SOTA and Kenneth provided some great details for finding the summit (which is not actually on the park grounds). It was great running into a fellow QRPer and talking shop, too! I hope to meet Kenneth again in the field.
I arrived at South Mountains State Park mid-afternoon and set up near one of their large covered picnic shelters.
Although I’ve activated South Mountains State Game Land numerous times in the past, I’ve never activated the actual park. The last time I popped by the park, there was already another ham there in the middle of an activation, so I moved to the adjoining game land that day.
South Mountains State Park is a very popular park–indeed, it’s currently the second most activated park in North Carolina. Although I didn’t realize it at the time because I had no internet access, there was actually another operator somewhere at the park on the air at the same time I was.
Once again, I set up the Chameleon CHA MPAS Lite vertical antenna for this quick activation.
Besides being such a quick and easy antenna to deploy, I love how stealthy it is, essentially disappearing against a background of trees.
As you might imagine, activating a park while someone else is also activating it is not ideal. At the time, I couldn’t figure out why contacts were coming in so slowly, but no doubt many hunters probably thought they’d already worked me because they worked the other activator.
In the end, though, my biggest problem at South Mountains was the fact my battery died in the Elecraft T1 ATU after finding a match on the 20 meter band. A 9 volt battery should last months in the T1, but the battery I put in it several weeks ago had already been used in another device for a few months. I had meant to replace it with a fresh cell. I actually packed a new 9V battery in my main radio pack, but I didn’t have it with me on this trip because both South Mountains and Lake James were unplanned activations.
I spent a good half an hour on the 20 and 30 meter bands where I had a decent match, but only logged three or four hunters. Conditions were not ideal on the higher bands.
I really needed to move down to the 40 meter band knowing it would be more productive, but I had no way to find a match for the IC-705. (Lesson learned: I’ll never again leave home without my Emtech ZM-2 as a backup!).
Fortunately, I remembered I had the Elecraft KX1 field kit. The KX1 now permanently lives in my car so I know I always have a complete radio kit for impromptu field activations.
The KX1 has a built in ATU, but it’s not as robust and versatile as the T1 or the internal ATUs in the KX2 or KX3.
I tried loading 40 meters and got a 2.5:1 match. I’m sure the KX1 would have plugged along, but I don’t like pushing much over 2:1 when I don’t have to.
After tinkering with the CHA MPAS Lite counterpoise for ten minutes, I finally found a length that, if half suspended, allowed the KX1’s internal tuner to achieve a 1.9:1 match. Good enough!
I started calling CQ on 40 meters and within a few minutes, I logged a total of 12 contacts.
The KX1 saved my bacon that Tuesday!
All in all, I really enjoyed the time at South Mountains State Park. It was beautiful weather and I had an idea spot to set up and operate. I’ll certainly come back here in the future.
I’ve also decided that I’m going to start packing a resonant antenna option in the car with my KX1 field kit. It’s only this year that I started using multi-band and random wire antennas that require an ATU; they are mighty convenient indeed, but it’s always nice to have a resonant option on hand as well.
Monday (November 16, 2020), I made a detour to the Catawba River access of Lake James State Park (K-2739) to try a late morning POTA activation.
I didn’t plot this activation in advance, so had to work with what I had in the trunk/boot of the car.
I did a quick inventory and found my Chameleon CHA MPAS Lite vertical antenna packed and ready to deploy. (I always have an antenna tucked away in the car because…well, because!)
In terms of radios, I had the Icom IC-705 and Elecraft T1 antenna tuner packed as well. Woo hoo! A perfect combo! Let’s go!
It was blustery and cold Monday morning due to a front that moved through during the night, so it was no surprise that the picnic area was completely void of (sane) people.
I found a picnic table on the bank that was relatively sheltered from some of the stronger gusts moving across the river. It was still quite windy, though, so I propped the MPAS Lite field pack on the table to provide a bit of a wind break for my log book.
Setup was quick. I don’t think I needed more than 4-5 minutes to have the CHA MPAS Lite deployed. This is one of the advantages of field portable verticals. The disadvantage? Verticals aren’t the most effective antennas in this part of North Carolina where ground conductivity is so poor. Still…I knew I could at least grab my ten needed contacts to have a valid POTA activation.
On the air
I won’t lie: it was slow-going.
For one thing, it was 11:00 local on a Monday morning–not exactly a prime time for a park activation.
I first tried making some SSB contacts on 40 meters and spotted myself on the POTA network. I managed to log 5 hunters in 30 minutes. With patience and time, no doubt, I could log ten SSB contacts, but I didn’t have time to wait, so I moved over to CW.
Oddly, the higher HF bands were in better shape than 40 meters that morning. One of my first contacts was NL7V in Alaska on 20 meters. A most impressive contact with 10 watts into a vertical.
I was on the air a full hour and did manage to log a total of 10 contacts. I’m certain if I would have deployed a wire antenna I would have had even better luck. Indeed, had I thought about it in advance, I could have actually deployed the MPAS Lite as a random wire antenna. (Doh!) That’s one of the great things about this antenna system is that it can be configured so many different ways. Next time…
Still…I thoroughly enjoyed my time at Lake James State Park. I’ll make this detour again in the near future.
The Icom IC-705 continues to prove its worth as a superb little POTA transceiver!
Yesterday, my family decided to make an impromptu trip to one of our favorite spots on the Blue Ridge Parkway at Richland Balsam–the highest point on the BRP.
Of course, it was a good opportunity to fit in a Parks On The Air (POTA) activation, but I had also hoped to activate Richland Balsam for Summits On The Air (SOTA) simultaneously.
It being well beyond leaf-looking season, we had hoped the BRP would be relatively quiet, but we were wrong.
Trail heads were absolutely jam-packed and overflowing with visitors and hikers. We’ve noticed a sharp hiker uptick this year in western North Carolina due in no small part to the Covid-19 pandemic. People see hiking as a safe “social-distance” activity outdoors, but ironically, hiker density on our single-track trails is just through the roof. One spends the bulk of a hike negotiating others on the trail.
The trail head to Richland Balsam was no exception. Typically, this time of year, we’d be the only people parked at the trail head but yesterday it was nearly parked full.
Being natives of western North Carolina, we know numerous side-trails and old logging/service roads along the parkway, so we picked one of our favorites very close to Richland Balsam.
We hiked to the summit of a nearby ridge line and I set up my POTA station with the “assistance” of Hazel who always seems to know how to get entangled in my antenna wires.
Taking a break from using the Icom IC-705, I brought my recently reacquired KX1 field radio kit.
I carried a minimal amount of gear on this outing knowing that there would be hiking involved. Everything easily fit in my GoRuck Bullet Ruck backpack (including the large arborist throw line) with room to spare.
I took a bit of a risk on this activation: I put faith in the wire antenna lengths supplied with my new-to-me Elecraft KX1 travel kit. I did not cut these wires myself, rather, they are the lengths a previous owner cut, wound, and labeled for the kit.
With my previous KX1, I knew the ATU was pretty darn good at finding matches for 40, 30, and 20 meters on short lengths of wire, so I threw caution to the wind and didn’t pack an additional antenna option (although I could have hiked back to the car where I had the CHA MPAS Lite–but that would have cut too much time from the activation).
I didn’t use internal batteries in the KX1, rather, I opted for my Bioenno 6 aH LiFePo battery which could have easily powered the KX1 the entire day.
I deployed the antenna wire in a nearby (rather short) tree, laid the counterpoise on the ground, then tried tuning up on the 40 meter band.
No dice.
The ATU was able to achieve a 2.7:1 match, but I don’t like pushing QRP radios above a 2:1 match if I don’t have to. I felt the radiator wire was pretty short (although I’ve yet to measure it), so clipping it would only make it less resonant on 40 meters.
Instead, I moved up to the 20 meter band where I easily obtained a 1:1 match.
I started calling CQ POTA and within a couple of minutes snagged two stations–then things went quiet.
Since I was a bit pressed for time, I moved to the 30 meter band where, once again, I got a 1:1 match.
I quickly logged one more station (trusty N3XLS!) then nothing for 10 minutes.
Those minutes felt like an eternity since I really wanted to make this a quick activation. I knew, too, that propagation was fickle; my buddy Mike told me the Bz numbers had gone below negative two only an hour before the activation. I felt like being stuck on the higher bands would not be to my advantage.
Still, I moved back up to 20 meters and try calling again.
Then some radio magic happened…
Somehow, a propagation path to the north west opened up and the first op to answer my call was VE6CCA in Alberta. That was surprising! Then I worked K3KYR in New York immediately after.
It was the next operator’s call that almost made me fall off my rock: NL7V in North Pole, Alaska.
In all of my years doing QRP field activations, I’ve never had the fortune of putting a station from Alaska in the logs. Alaska is a tough catch on the best of days here in North Carolina–it’s much easier for me to work stations further away in Europe than in AK.
Of all days, I would have never anticipated it happening during this particular activation as I was using the most simple, cheap antenna possible: two thin random lengths of (likely discarded) wire.
People ask why I love radio? “Exhibit A”, friends!
After working NL7V I had a nice bunch of POTA hunters call me. I logged them as quickly as I could.
I eventually moved back to 30 meters to see if I could collect a couple more stations and easily added five more. I made one final CQ POTA call and when there was no answer, I quickly sent QRT de K4SWL and turned off the radio.
I still can’t believe my three watts and a wire yielded a contact approximately 3,300 miles (5311 km) away as the crow flies.
This is what I love about field radio (and radio in general): although you do what you can to maximize the performance of your radio and your antenna, sometimes propagation gives you a boost when you least expect it. It’s this sense of wireless adventure and wonder that keeps me hooked!
Yesterday, I *finally* activated two parks that have been on my list for most of the year: Elk Knob State Game Land (K-6903) and Elk Knob State Park (K-2728).
The game land had never been activated which I found quite puzzling since it seemed to be accessible based on my maps and was only 1.5 miles from (actually adjoining!) a state park which has been activated a number times.
Turns out, there’s a good reason it hadn’t been activated.
Elk Knob State Game Land (K-6903)
Upon entering the game land parcel, you’re greeted by the sign above which states that while the game land is a public resource, it is private land and the owner only allows hunting and trapping on it. First time I’ve ever encountered this.
This meant that I really couldn’t cross the barb wire fence that lined the one lane dirt road to activate the park in the woods (which I would have preferred).
Fortunately, I found one pull-off in the middle of the game land road. It was just wide enough to fit my car so that others on the road could pass me without a problem. It was rather tight, though.
Since I didn’t want to use a tree on the game land to support my antenna, I employed the Chameleon CHA MPAS Lite 17′ vertical.
I pushed the MPAS Lite spike into the ditch of the road and ran the counterpoise along the ditch as well. All was within the road right-of-way, yet within the game land so I felt it a proper compromise respecting the land owner’s wishes while still being able to activate the park.
For this activation, I chose the Elecraft KX2 since I had such a limited space in the back of my car to both operate the transceiver and log.
The great thing about the KX2 is it’s such a complete & compact package: it’s a transceiver, with an internal battery pack (that allows 10 watts of power), a built-in ATU, and attachable paddles. Everything easily fits on my clip board which then functions as an operating table.
I started calling CQ POTA and was quickly spotted to the POTA spots page via the Reverse Beacon Network (RBN).
I very quickly logged a number of stations in CW, but did eventually reach one road block when one of the contact posts in my KXPD paddles loosened. I’ve had this happen before. Thankfully, I keep precision screwdrivers in my EDC bag, so could make the fix. Unfortunately, it took me off the air for a good 5-10 minutes and I lost my pile-up.
I eventually changed modes and called CQ a few times on 40 meters phone.
In the end, I only logged 13 contacts. Certainly the smallest number I’ve ever had at an ATNO (All Time New One). I felt I had to cut it short, though, as cars/trucks had to slow down to pass me. Twice I was asked if I needed any help (assuming my car had broken down).
I was very grateful to have the CHA MPAS Lite antenna in my arsenal, though. I have few other antenna options that would have worked so effectively in such a tight space.
The MPAS Lite is also incredibly stealthy. I’m not sure many passersby even noticed it.
On to the next park!
Elk Knob State Park (K-2728)
Where Elk Knob Game Land was an incredibly challenging site, adjoining Elk Knob State Park was the complete opposite. A POTA activator’s dream site.
This was my first visit to Elk Knob State Park and I was most impressed. Not only is the park gorgeous and quiet, but the picnic area is expansive, well-spaced, and there are numerous large, old-growth trees. Absolutely perfect for POTA purposes.
Since I had the luxury of these tall trees, I decided to employ the CHA Emcomm III Portable which has quickly become my favorite field antenna. When I have the space, I use it because it gives me 160-6 meters and is easily matched by all of my antenna tuners.
Since I had a great picnic table surface to operate, I also used my Icom IC-705 transceiver and Elecraft T1 antenna tuner.
So turns out, I didn’t take a lot of photos of my site because I used my iPhone to make a video of the activation.
On YouTube, I’ve been encouraged by viewers/followers to continue making real-time, real-life videos of some of my park activations. These videos have no edits and are what I would generously call “Ham Radio Slow TV.” 🙂 The idea is the viewer is simply joining me as I set up and operate at a park–as if they were there with me in person. I hope there’s some value in these videos for newcomers to Parks On The Air.
The video ended up capturing the whole activation from start to finish. If you need something to put you to sleep, check it out:
Video
All in all, it was a brilliant day and I’m pleased to have finally activated these two POTA sites.
It was a particular treat to discover Elk Knob State Park. I can’t wait to go back there to camp and to hike their trails.
Perhaps this is one of my favorite side benefits of Parks On The Air: it gives me a reason to explore state parks I might have otherwise overlooked. We’re huge supporter of state and national parks, so it’s truly a win-win!
In my head, this was going to be a post talking about antenna compromise vs. convenience vs. performance. I set out to make a point and will do just that. But it’s not the point I intended to make.
The Elecraft AX1 Antenna
For those of you not familiar, Elecraft designed a super compact portable antenna for the KX3 and KX2 called the AX1 a couple years ago. It’s, by far, the most compact HF antenna I’ve ever owned or operated.
What makes it so unique is that no one section of it is longer than 6″, which means when disassembled, it’ll fit in a very small pouch or pocket.
I purchased the AX1 a couple months ago. I bought the antenna, (which handles 20/17 and 15 meters), the 40 meter extension, bipod, tripod mount, and both counterpoises were included.
It’s a cool piece of antenna kit for sure! And so compact!
But let’s face it: it’s a compromised antenna!
An antenna this small and compact is not as efficient as a longer resonant wire antenna. Not even close.
The AX1 wasn’t built for performance per se–although it’s as efficient as it can be for the size–it was built for convenience!
You can set the AX1 up anywhere, anytime.
A POTA Experiment
A few months ago, a reader who owns a KX3 asked me if I thought he could successfully activate a (Parks On The Air) park with the AX1.
My reply:
“Sure! Especially if you’re using CW and you have a whole lot of patience.”
Yesterday morning, I decided to test my theory.
I drove to the Blue Ridge Parkway (K-3378) and parked at the Folk Arts Center. I found a picnic table (wasn’t hard at all considering it was hovering around freezing and incredibly breezy!) and set up my station.
It takes me maybe 3 minutes to set up the entire station.
The antenna fits together quickly (I was operating 40 meters, so used the optional extension and 31′ counterpoise).
Three minutes later, I’m ready to rock and roll!
On The Air
I had errands to run in town so didn’t want to spend all day doing this experiment, but I was determined to complete a valid POTA activation which requires 10 total contacts.
Before leaving the house, I scheduled my activation on the POTA site, so it would know to scrape my spot on the Reverse Beacon Network.
Keep in mind, this was taking place on a Monday morning around 10:15 AM and I was activating a park almost every POTA hunter has logged numerous times. The Blue Ridge Parkway is one of the most activated parks in the POTA network, so not exactly super desirable.
In addition, propagation number were pretty dismal.
I fired up the KX2, pressed the ATU button, and achieved a 1:1.1 match.
I called CQ POTA three times in CW.
Evidently, the RBN picked me up quickly, because I received a call.
Then another call.
Then a small pile-up of calls.
Next thing I know, I’ve logged five stations in five minutes.
I called CW again, and had another small pileup.
Short story short, I had achieve a valid activation in all of 12 minutes.
12 freaking minutes!
Seriously? My point was to prove it takes patience when using extremely compromised antennas.
After logging 12 stations, a received a phone call on my mobile and left the air (no other stations were calling me at that point and, again, this wasn’t a highly desirable or rare park). After my phone call, I decided to pack up and finish my errands in town.
After I returned home, I realized: this was easily my quickest field radio deployment and park activation.
The activation took me a total of 20 minutes: 3 minutes to deploy, 12 minutes on the air, and (generously) four minutes to pack up.
Let’s face it…
The stars were aligned Monday morning.
The AX1 is a compromised antenna but it’s obviously also quite effective.
The irony was en route to the activation, I was listening to the latest episode of Ham Radio Workbench. They were discussing wire antennas and how incredibly compromised shortened verticals are.
I was in complete agreement about compact antennas: sometimes, the compromise is worth it for the convenience.
Now, I would add: sometimes, it’s all convenience, performance, and no compromise whatsoever!
Next, I plan to attempt an SSB activation with the AX1. I do believe it’ll take quite a while to gather 10 stations for a valid activation. But who knows?
At least 95% of the time I’m playing radio in the field, I use wire antennas and suspend them in trees.
Since I do a lot of park activations for the POTA program, trees are typically very easy to come by and most of the time the park office doesn’t care if I hang an antenna in their tree for a couple of hours.
For years, I’ve been using a heavy steel nut–a nut that would fit a very large bolt–as a weight and attach it to fishing line. I then simply throw the nut into a tree and pray the fishing line deploys properly. I have reasonably good aim, so–on a good day–I typically only need one or two throws/tries to get the fishing line over a branch. On bad days? Well… let’s just not talk about that.
There are some inherent weaknesses in the fishing line/monofilament system:
First of all, I’m lobbing a heavy metal object into the trees. If it ricochets–and it eventually will–it can come back down to earth and land where you might not want it to (for example, on your radio, on your car, or on your friend’s head). Fortunately, I’ve never hit anything or anyone as I’m careful to clear the area first, but unfortunately, I once had the nut hit a tree and come back down near me. That was a little scary.
Secondly, fishing line isn’t exactly recyclable and you simply can’t use it over and over. I get at most three deployments with a section of fishing line before it gets too stretched and unworkable.
Finally, fishing line is incredibly prone to tangle, especially near the end of the spool.
A Better Solution? The Arborist’s Throw Line
The arborist throw line is no recent innovation. For years, I’ve read recommendations from other ham radio operators who swear by arborist throw lines but I only recently decided to take the plunge after one very frustrating park activation where my fishing line knotted and almost got permanently stuck in a gorgeous tree. I’m very much a “Leave No Trace” kind of guy, so I was incredibly relieved when I was finally able to work the fishing line out of the tree.
I once talked with an arborist about throw lines and he stressed the importance of getting not just the line, but also a throw line storage cube. The cube allows you to both deploy and take up the line without any tangles or knots.
All in, I spent about $50.00 US for both.
Preparing the throw line
My arborist buddy gave me an important tip: the throw line needs to be stretched.
As you can see in the photo above, the throw line is packed in a bundle that’s easy to unroll. After you unroll it for the first time, though, the line has a “memory” of all those bends from its life in the package.
You can remove much of the throw line memory by tying one end of the line to a tree and stretching the line to its full length. The line is 150 (or so) feet long, so you’ll need an open space to do this.
The arborist in this video shows how this is done (I’ve queued it to the point in the video where he shows how to do this):
Knots
You’ll need to attach the throw line to the throw weight, of course.
There are a number of knots arborists use, but I’m a fan of the slipped simple noose knot. Perhaps it’s because it’s easy to tie even with semi-rigid line, it holds quite well and, most importantly, it’s easy to untie.
Looks like arborists use it too because when searching for an instructional video, the first result was from an arborists’ channel:
Throwing up!
There are a few different ways to launch a throw line into a tree.
Take my advice here: practice at home before you hit the field! It could save you a lot of embarrassment, although, admittedly, my at-home practice sessions gave my wife and my daughters good reasons to chuckle.
I’ve only been using the throw line for a little over a week, so I’m still sorting out which method works best for me. One thing I discovered very quickly, though: no matter which launch method I use, I can send that throw weight into a tree at least 60% higher than I could before.
No doubt, the throw line and weight really put the laws of physics in your favor!
Here’s a great video highlighting different throw line launch techniques:
In practice
I took the throw line to the field today for the first time and I’m very pleased with how effectively it works.
I was able to place my antenna on a much higher branch than I could have otherwise. It took me three tries today, but it had more to do with my poor aim. As with any skill, this will, I think, improve with practice.
Besides the improved antenna height, I love that the line can be used over and over again. Also, it’s strong enough that should it ever get caught in a tree, I can pull it out without the line breaking.
I can also reel in the line at least three or four times faster than I could with fishing line. Simply flake it into the storage cube one foot at a time.
When the line has been stored along with the throw weight, you can fold the storage cube down flat, then fold and secure it into a compact triangle.
Are there any negatives with the throw line system? Here are a few I’d note:
Bulk. Even when packed down, the line in the storage cube take up much more space than fishing line. Although it easily fits in even my smallest backpack (the GoRuck Bullet), I’m not sure I’d take it on a long hike.
This system requires a little practice and skill–you can’t pull it out of the package for the first time in the field and expect perfect line launches.
The throw line is more conspicuous than fishing line. If you’re trying to be a bit stealthy–as many of us are these days during the Covid-19 pandemic–the bright yellow throw line will attract more attention and questions from other hikers/campers, etc.
Even though it’s bulky by my standards, I see the throw line becoming a permanent part of my field kit and I expect I’ll use it on most of my POTA activations.
Have you been using a throw line to hang field antennas? Or do you use a different system? Please comment!
