POTA Field Report: Activating the BRP with my new-to-me Icom IC-703 Plus

When my buddy Don told me he was selling his Icom IC-703 Plus a few weeks ago, he caught me in a (multi-year long)  moment of weakness. I asked his price and followed up with a PayPal transaction without giving it a lot of thought. It was a bit of an impulse purchase, if I’m being completely honest, but he definitely gave me a “friends and family” discount.  (FYI: Don is the same enabler that made this purchase happen.)

I’m thinking the IC-703 Plus might be a good first HF rig for my daughter (K4TLI) and, of course, it’ll be fun to take it to the field from time to time.

Of course, the best way to get to know a radio, in my opinion, is to take it to the field. So that’s exactly what I did last week (January 13, 2021).

Blue Ridge Parkway K-3378

Against my better judgement, I decided to make a video of the activation. I mean, what could possibly go wrong operating a radio for the first time in the field? Right–?

I picked out an “easy” park for this activation: the Blue Ridge Parkway.

Although most of the parkway around Asheville, NC, is closed to vehicle traffic, the Folk Art Center is open year round and a very convenient spot for POTA.

Gear:

I paired the IC-703 Plus with my Chameleon MPAS 2.0 vertical antenna. I was curious how easily the IC-703’s internal ATU could match the MPAS 2.0: turns out, pretty darn well!

I started the activation on 40 meters phone (SSB).

Almost immediately, I logged a few contacts and that quickly built my confidence that even the default voice settings were working well on the IC-703 Plus.

I then moved to 40 meters CW and used the CW memory keyer to call CQ (I pre-programmed this before leaving the QTH that day).

Then I experienced a problem: when someone answered my call, my keyer didn’t work properly. For some reason, it was sending “dit dash” strings from both sides of the paddle. I’m not entirely sure what happened but assume there was either a radio glitch or a small short in my paddle cable. After fiddling with the IC-703 for a bit, I pulled out my Elecraft KX2 and finished the CW portion of my activation. (Always carry a spare radio, I say!)

Actually, I assumed since I was using the IC-703 for the first time, there could be hiccups as I did not do a full rig reset prior to putting it on the air–settings were essentially what they were when Don had the radio.

Here’s one of my real-time, real-life no edit videos of the entire activation, if you’re interested:

Back home, I connected my CW Morse paddles up to the IC-703 and it worked perfectly. Even though I checked the connections in the field, I must assume one of the plugs simply wasn’t fully-inserted. It hasn’t repeated this since.

Despite the CW snafu, I’m very pleased with the IC-703 Plus so far. I like the size for tabletop operating and it’s actually surprisingly lightweight.

If you own or have owned the IC-703, please comment!

Mistakes and miscalculations might make us better field radio operators

I don’t know about you, but part of the fun of playing radio in the field are the inevitable frustrations.

It might not feel like it in the moment, but when I eventually overcome the challenges of a mistake, I feel like I’ve truly accomplished something.

That was my little epiphany this morning: making mistakes has perhaps made me a better radio operator. Less-than-efficient field deployments have honed my skills and had a major influence on the gear I pack.

If you’ve read some of my (rather rambling) field reports in the past, you’ll note that I rarely do field activations with the exact same gear combinations each time. I feel fortunate enough that I can pair different radios with different antennas and different accessories.  I get a small thrill out of not knowing exactly how well a combination will work, especially if I’m not activating a rare all-time new park or tough summit for that matter. In cases where getting to the site is a challenge in and of itself, I want to use a trusted combo of gear.

It’s that wee bit of mystery that attracts me to the field.

If I approached POTA more like a contest–where activation and contact numbers were my focus–I would have installed a mobile HF rig in my car a long time ago. I could rack up way more parks and contacts that way. It especially simplifies multi-site activation days since it effectively eliminates the time involved in setting up and later packing up gear.  Mobile operating is the most efficient way to hit number goals: drive up to a site, start calling CQ, work your stations, then move on.

Yesterday, I did a last minute “two-fer” activation of Pisgah National Forest and Pisgah Game Land. I had not planned to do an activation that day–temps never rose above 29F (-2C) at the QTH day and it also snowed and flurried all day long. Winds were very gusty as well, so it effectively felt much colder on the skin.

I wanted to hike up to the ridge line behind my QTH and do the activation but I knew up there temps would be lower and (worse) winds much stronger. Cold doesn’t really bother me, but strong winds do. This was also the first weekend my ankle felt almost normal after twisting it badly last month. It’s healing and I hope will be in shape for a long hike from my QTH to a six point SOTA summit next weekend with my daughter (K4TLI).

All of those factors combined pointed toward simply staying at home, drinking coffee, and reading a book.

Hazel was ready for some field radio fun, though. (Photo credit: K4TLI)

But I really wanted some outdoor time. And I really wanted to make an activation with my Elecraft KX1, so I decided that instead of hiking up in elevation 800 feet, I’d drive down about 900-1,000 feet to a forest trailhead. That would get me on the air in a protected valley with less wind,  less snow, possibly warmer temps, and much less hiking which would be easier on my ankle.

The Last-Minute Antenna

When I use the KX1 in the field, I typically pack a very simple antenna: one length of radiator wire and one length of counterpoise wire–connected to a BNC binding post adapter, I let the built-in ATU sort out the match.

When I owned my first KX1, I had a magic length of radiator wire (the length of which I can no longer remember) that seemed to work amazingly well  on 40, 30, and 20 meters.

My new-to-me KX1 came with two lengths of wire: one 23′ and one about 20′. Although I made a fun and successful activation with this setup, the radiator was simply too short for the KX1 to find a decent match on 40M.

On the way out the door, I decided to cut a new radiator and counterpoise out of scrap wire I use for antenna experiments.

Being a bit stubborn and also in a hurry to beat sunset, I did no Internet research to sort out the ideal lengths for 40 meters.  I simply cut a 17′ length for the counterpoise and about 27.5′ for the radiator.

In the Field

After arriving on site, I deployed the antenna and tried finding a match on 40 meters with the KX1’s internal ATU.

No go.

I tried a few times hoping maybe the ATU would find something even semi-reasonable in terms of a match, but there simply wasn’t enough radiator to make it work. That was a shame because forty meters would have been the ideal band for yielding quick contacts this time of the afternoon.

I had options, but I wanted to make what I had work.

The activation took time and patience. The 30 meter band was now my best bet and it’s where I logged all ten contacts for a valid activation. I tried 20 meters where I had a 1:1 match, but the band was dead.

At one point, I switched out the KX1 with my KX2 that I also packed. I tried to find a 40 meter match with the superior KX2 ATU, but physics got in the way again. 🙂

40 meters was an option

Let’s be clear here: I could have easily cut 4′ off of the counterpoise and attached it to the radiator and I bet I would have gotten a match on 40M. Since the counterpoise was lying on the ground, its length was less crucial.

The EFT Trail-Friendly end fed antenna was also in my pack.

I also had a perfectly capable 40/20/10 en-fed antenna in my pack. Switching out the antenna would have only taken four minutes.

I bet I could have easily yielded 20 additional contacts on 40 meters because the band was in great shape. Almost without fail, 40 meters is my most productive band.

Working with limitations

Thing is, I’m starting to understand that I like working with self-imposed limitations.

Perhaps this is why I love QRP and low-power radio so much: I get a little thrill out of doing more with less.

Yesterday, even after I realized it would be a struggle to log my final three contacts on 30 meters, I persisted. One motivation was I’ve never completed a full activation using only 30 meters. With a little patience, I knew I could snag my ten contacts.

The only things making it a challenge were the facts that temps were dropping rapidly, winds were picking up, and the sun was setting. Hazel (the POTA dog) who so eagerly jumped in the car when she saw me put on my hiking boots earlier, was also starting to shiver.

Fortunately, after trying another short stint on 20 meters, I returned to 30 and worked two more stations in quick succession giving me a total of nine contacts.

It started to get darker, so I hunted and found an operator calling CQ  on 30 and simply made contact with him. He wasn’t a POTA station, just a general CQ call. He kindly gave me his details for the logs.

Lessons learned

I made a video of most of this activation and will upload it when I have a little bandwidth to do so. I’ll embed it in a shorter field report here on QRPer since I’ve described so much already.

Even though it was a challenge making ten contacts to accomplish a valid field activation with my time constraints, I’ll admit that I really enjoyed the challenge.

Next time I head to the field with the KX1, I’ll actually test the antenna prior to leaving the QTH.

In fact, I’m planning to make two radiators: one at an ideal length for 40 meters and above, and another–much longer–for 80 meters and above. Any advice and personal experience from KX1 owners would be much appreciated.

Perhaps most importantly, it’s only now dawned on me how much I enjoy making the most with self-imposed limitations or “trying to make lemonade with lemons.”

Do you feel the same? I’d love to hear your comments.

POTA Field Report: Bonneau Ferry Wildlife Management Area (K-3888)

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!)

My entire station!

Gear:

On The Air

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!

POTA Field Report: Ernest F. Hollings ACE Basin National Wildlife Refuge (K-0520)

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.

Ernest F. Hollings ACE Basin National Wildlife Refuge is a case in point.

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!

Our walk to the main house and visitor center.

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.

Gear:

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!

Impromptu POTA activation using the Elecraft AX1 Antenna

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.)

Gear:

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.

POTA Field Report: A Tale Of Two Parks (And Two Antennas)

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.

Gear:

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.

Gear:

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.

The CHA Emcomm III Portable

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!

Can you activate a park with the Elecraft AX1 portable vertical antenna–?

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

My Maxpedition Fatty Pouch has more than enough room for the AX1, tripod adapter, bipod, antenna, 40M section, and two counterpoises.

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

The AX1 is in the Maxpedition pack on the left, my KX2 in the Lowe pack on the right.

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?

Stay tuned!

Hiking to a POTA “two-fer” site from home

I feel pretty lucky that my QTH borders tens of thousands of acres of protected lands: a watershed, Pisgah National Forest, and Pisgah Game Land WRC. Our family enjoys hiking, so we often venture into the forest around our house  and explore the ridge lines, peaks, and views.

This year, while exploring all of the public lands available to activate in the Parks On The Air (POTA) program, I realized there were no less than two sites within a 30-35 minute hike of my home! Quite literally, in my back yard.

In fact, there’s a large area where two POTA entities overlap–Pisgah National Forest and Pisgah Game Land–giving me the opportunity to activate both sites simultaneously as a “two-fer.”

If it’s so close, you may wonder why I haven’t activated it yet–? Well, by the time I realized the park boundary overlap was within hiking distance of the house, we were well into spring, thus the forest was lush with vegetation and the hike to the site requires proper trail-blazing with an elevation change of 600′ (183M). It’s a much easier hike in fall and winter when you can actually see where you’re going through the trees.

Still: Saturday morning, the weather was so perfect for hiking I floated the idea by my teenage daughter, Geneva: “I’ve got a hankering to hike up the mountain today and do a POTA activation.” She replied, “I’ll need to pack my daypack and take the HT.” She was eager to see if she could communicate back to the house simplex with her mom and sis with her new FT-60R handheld.

My wife gave me her blessing, so I packed my trusty Red Oxx C-Ruck with my Elecraft KX2 kit, CHA Emcomm III Portable antenna, water, snacks, logbook and tablet, and used the ruck top flap to secure my three leg folding stool.

Pisgah Game Land WRC (K-6937) & Pisgah National Forest (K-4510)

We arrived at a suitable site about 40 minutes after leaving the QTH. My Garmin GPS and topo maps confirmed we were well within park boundaries. I found a rock outcropping and set up my station.

Even though the area was pretty dense with trees, Rhododendrons, and Mountain Laurel, I had no difficulty deploying the Emcomm III Portable antenna using my throw line.

That’s not a flying squirrel, it’s the winder/balun of the Emcomm III.

The Elecraft KX2 had no trouble at all matching the Emcomm III on all bands.

Even though Geneva was busy communicating with her sister (back at “Mission Control” via simplex) on the FT-60R, she actively logged all of my contact on the Surface Go tablet using N3FJP’s excellent contact log.

I quickly logged eleven contacts on 80 and 40 meters and my daughter suggested we cut the activation a bit short to take in more hiking.

We both wanted to follow a trail we found and see if it lead to the Blue Ridge Parkway.

Hazel has that “Seriously? You want to continue hiking?” look.

I packed up the station and hit the trail!

It turned out to be a good 45 minute trek along a ridge line increasing our elevation about 1,000′ (305M) ASL compared with home. The trail to the BRP was what I would call a moderately difficult trail (much easier than trail-blazing up the mountain!).

In the end, we found the Blue Ridge Parkway and the trail head to ascend Lane Pinnacle which is an excellent SOTA site. We decided to save Lane for another day this fall/winter with a very early departure from home.

Neva also discovered she could easily chat with her sister back at the QTH via 2 meter simplex at the parkway. This means I can definitely chat with the family back home when I eventually make that Lane Pinnacle SOTA activation.

The hike back to the POTA site was mostly downhill so only took about 40 minutes. I then veered off the path to trail-blaze our way back to the house. I did get a little off course which added about 25 minutes (!!) to our descent and requiring us to mitigate the steepest part of the ridge. Next time, I’ll pay more attention to my GPS map (although, in the winter, it’ll be much easier).

Still, it was a very enjoyable hike and certainly one of the more challenging I’ve been on in ages mainly due to the steep part at the end.

All-in-all: I discovered that there are no less than three POTA sites and one SOTA site within hiking distance of the QTH. The best part, by far, was the father/daughter time. Geneva is always up for an adventure (including currently studying for her General class license!).

Seven Park Activations in Six Days: A review of the adaptable Chameleon Emcomm III Portable antenna

Weather in North Carolina has been absolutely stunning over the past week, with the exception of two days where the remnants of Hurricane Sally dumped torrential rain. Two cold fronts provided us with gorgeous clear skies and dry conditions before and after Sally’s visit.

Of course, what better way to enjoy the outdoors than taking my radios to the field?

Last Wednesday, after several hours of knocking out home projects, my wife and I decided to enjoy the fall-like weather and get lost in Pisgah National Forest. My daughters were also keen for a little outdoor adventure, waterfalls, and hiking.

And our canine family member, Hazel? Always up for an outing!

“Let’s go, daddy!”

Of course, my wife was throwing me a bone as she knew I was chomping at the bit to try the new-to-me Chameleon Emcomm III antenna.

I decided I’d pair the Emcomm III with the amazing Mission RGO One transceiver (a rig I’ll be reviewing in an upcoming issue of The Spectrum Monitor magazine).

Up to this point, I’d never used a Chameleon antenna in the field.

Chameleon Antenna kindly sent me both the CHA Emcomm III and CHA P-Loop a couple weeks ago for an honest field evaluation (and disclaimer: at no cost to me).

And being honest? The overall length of the Emcomm III wire antenna was intimidating.  I’m used to field-ready wire antennas that are perhaps 30-41 feet in total length. The Emcomm III has a 73 foot long radiator and 25′ counterpoise! Holy smokes!

In my head, I imagined the only places I’d be able to use the Emcomm III would be in an open park with large, widely-spaces trees.

Turns out, I was wrong.

Two things make deploying the Emcomm III a breeze–even in the middle of a forest:

1.) An arborist throw line: this piece of kit has revolutionized my  field antenna deployments. Not only does it give me the ability to suspend antennas much higher than I could before, but also to raise/lower antennas with ease compared with fishing line.

2.) The Emcomm III also has a floating dielectric ring on the radiator wire that allows you to create a suspension point. In fact, there are a number of ways you can deploy the Emcomm III which, I see now, makes it such a popular antenna among POTA operators.

To the field!

The first activation was actually a “two-fer”–meaning, two geographically-overlapping POTA park entities.

Wednesday, September 16: Pisgah National Forest (K-4510) & Pisgah Game Lands WRC (K-6937)

Propagation conditions on Wednesday were so crappy I found myself breaking with QRP to run 40 watts with the Mission RGO One into the Emcomm III. (The Emcomm III can actually handle up to 50 watts CW, 100 watts SSB.)

I first deployed the Emcomm III by pulling the radiator over a tree branch about 50′ high with the balun and winder near the ground. I then unrolled the counterpoise stretched out on the ground.

After only snagging about eight contacts in 50 minutes (a very meager amount for the typical park activation), I decided to re-configure the Emcomm III Portable so that it would act more like a NVIS antenna and perhaps grab a few regional hunters on 80 meters. There was no way I was leaving the forest without my 10 contacts to validate the activation!

I reeled in the radiator and re-attached my throw line to the floating loop and reconfigured the antenna to roughly match this “V” shape with a lower (roughly 25 ft) apex point:

NVIS “V” configuration (lifted from the CHA Emcomm III Portable product page)

I used the RGO One’s internal ATU to match the 80 meter band 1:1.

I started calling CQ on 80 meters CW and, evidently, the POTA site auto-spotted me via the Reverse Beacon Network (RBN) because within a minute, I found myself at the other side of a mini pile-up! I very rapidly worked 8 stations–most of them were in nearby Tennessee. These were callsigns I was not used to logging because typically they’d be under my skip zone–a little too local.

It was nice to get solid copy on 80 meters without the deep QSB on 40, 30 and 20 meters.

The thing that struck me about the Emcomm III at this first activation was how easy it was to reconfigure in the field despite the lengthy radiator. The wire is Copper Clad KEVLAR PTFE (Telflon-coated) and doesn’t easily tangle. It slides so easily through the trees–there’s no coil or bulky bits to get caught in the limbs.

When packing up, it wraps around its built-in winder very easily. Kudos to the designer.

Saturday, September 19: Pisgah National Forest (K-4510) & Pisgah Game Lands WRC (K-6937)

Last Saturday, I wanted to try the CHA Emcomm III in a different region of Pisgah National Forest and see how well it might pair with my Elecraft KX2.

We found an ideal spot to set up: a forest service road that had obviously been closed the entire season.

I deployed the Emcomm III Portable in the same “V” configuration as I did during the first activation, but this time raising the apex of the “V” up to 45 feet.

It’s important to note here that being a random wire antenna, the Emcomm III relies an an ATU to get good matches on each band. The Mission RGO One’s internal ATU did a brilliant job finding matches and, turns out, my KX2 did as well.

In fact, before I started calling CQ, I moved across the bands to see if I could get good matches with the KX2 ATU. From 80-20 meters, I think the highest SWR I had was 1.3:1. (The KX series ATU is truly a benchmark in my book!)

That day, even though the weather was gorgeous, propagation was terrible.  I read a few reports from experienced POTA and SOTA folks who couldn’t snag the needed 10 contacts for a valid activation earlier that day. There were contests and QSO parties on the bands so lots of signals–but more than once on the phone portion of the 40 meter band,  I could hear two stations calling CQ on the same frequency and trying to work the same stations totally unaware of each other. Not a good day to play radio in the field and was starting to wonder if I could even snag my needed ten contacts.

Turns out, I had nothing to fear.

Since I could, quite literally, pick any band the KX2 could transmit on, I was able to float across the HF spectrum, call CQ, and the RBN would make sure I was spotted properly to the POTA network.

Getting that first ten is a great feeling!

I pretty effortlessly snagged my ten, and then a number to boot.

When I seek a spot to set up in a national forest, I often look for forest service roads with locked gates. When I set up on an unused road, it typically means I’ll have a high branch to hang the antenna and also a little space to deploy it without touching other trees. Our spot on Saturday was ideal.

Again, hanging and deploying the Emcomm III was effortless. I did bring about 12 feet of paracord with me this time allowing me to tie off the end of the radiator if I chose the “V” shape.

Monday, September 21: Mitchell River Game Land (K-6926) & Stone Mountain State Park (K-2754)

Monday was another stunning weather day.

I decided I wanted to finally make a pilgrimage to an ATNO (All Time New One) POTA site I’d been eyeing for a few months: Mitchell River Game Land.

Because propagation was fickle and this site was a good 3 hour round trip from where I was staying with family, I planned to use the Mission RGO One and run 40-50 watts or so.

However, when I got to the site, I realized I’d left the RGO One’s power cable at home. Fortunately, I still had my Elecraft KX2, so 10 watts would have to do.

I found a large parking pull-off area surrounded by trees. There was a ton of room to deploy the Emcomm III.

I decided to extend the radiator in a sloping configuration and elevate the 25 foot counterpoise.

The configuration was Identical to the one above , but the balun/center winder and counterpoise were suspended about 4 feet off the ground.

I fired up the KX2  and started calling CQ on 80 meters. The RBN picked me up and the POTA site auto spotted me. In a couple of minutes, I snagged my first three stations, then I heard no other calls, so moved up to 40 meters where I worked a big pile-up of stations. It felt like a mini-DXpedition at times. I loved it!

I even hopped on the phone portion of the 40 meter band and worked a few stations, getting respectable signal reports despite unstable propagation.

This activation went so well and the weather was so ideal, I decided to fit in another park that was only a 30 minute drive and was new to me: Stone Mountain State Park.

The thirty minute drive was relaxing and reminded me how much I enjoy this portion of the NC foothills leading up to the Blue Ridge Parkway and escarpment.

By the time I reached the park it was 1:30 pm on a Monday and I essentially had the place to myself (even though in my head I was preparing for crowds).

I had my pick of picnic spots so I found the one with the highest branches. One shot with the arborist throw line and I snagged a branch that must have been 45-50 feet high.

I first deployed the Emcomm III by simply running the radiator over a tree branch and laying the counterpoise on the ground–much like I did in the first Emcomm III activation and deployment.

I started calling CQ and worked about 4 stations, then nothing. The bands simply died on me!

After 30 minutes, I reconfigured the Emcomm III into a similar “V” shape I used at Pisgah National Forest with the apex at about 40 ft and the center winder and counterpoise elevated about 3 feet.

After some persistence, I finished off my ten contacts and then packed up–I spent about 70 minutes on the air and needed to grab lunch!

I honestly believe I would have found this activation even more challenging if I didn’t have an antenna that could snag stations on the 80 meter band since it was in the best shape that afternoon.

Again, I was very impressed with how easy it was to reconfigure the Emcomm III.

Tuesday, September 22: Tuttle Educational State Forest (K-2754)

After staying two nights with my parents in the Piedmont of North Carolina, I made my way back home to the mountains Tuesday afternoon. Again, the weather lured me back out to make just one more activation! (Let’s face it: the weather is a bit of an excuse).

One of my favorite parks that’s only a 20 minute detour off my path is Tuttle Educational Forest. It’s never busy there and they have a large picnic area with ideal trees for hanging antennas.

After searching through my main field pack (a Red Oxx C-Ruck), I found a spare power cord that would work with the Mission RGO One transceiver.

I didn’t have a microphone, though. That’s okay: it would be a CW-only activation.

Although I had the park to myself, I didn’t want to take up a large portion of the picnic area by deploying the Emcomm III in a sloping configuration similar to my activation at Mitchell River. I decided, instead, to be space efficient and use the “V” configuration once again with the apex at about 35 feet and the counterpoise on the ground. By doing this, the antenna footprint could almost fit within my picnic table area (although my counterpoise did snake into the woods).

I can’t remember how long I was on the air, but I do remember it was a breeze logging contacts that afternoon. Very enjoyable. I do love the Mission RGO One–the receiver is amazingly quiet, sensitive, selective, and signals simply pop out of the ether. It also sports silky-smooth QSK. Again, although I’m 90-95% a QRPer, it’s nice to push the juice a bit when propagation isn’t kind. The RGO One will push 55 watts.

The Mission RGO One ATU also snags excellent SWR matches across the band with the Emcomm III.

Emcomm III initial impressions

This past week, I gained some serious respect for the Emcomm III.

What impresses me most is its versatility and robust quality.

Don’t get me wrong: it’s not a magic antenna or anything. It’s essentially a random wire antenna.

What makes it such a fabulous field antenna, though, is its configurability. That and its uncompromised military-grade construction.

I shouldn’t have been so concerned about the radiator length as it’s actually pretty easy to accommodate and helps make this an efficient antenna on the low bands. (Look for me activating parks on 160 meters this winter!)

I believe I can deploy the Emcomm III anytime I have a half-decent tree nearby. I believe I could also use my 31′ Jackite fiberglass pole to extend one end or even the middle of the antenna if I wanted to go NVIS, but I would have to be careful to accommodate strain relief since the Emcomm III Portable is made of heavier materials than my EFT Trail-friendly antenna, for example.

I’m not sure I’d ever reach for the Emcomm III for a SOTA activation when I’d need to take a close look at weight and size. But for POTA? It’s brilliant. And, of course, for emergency communications (as the model name implies). The Emcomm III would also be an excellent addition to a radio club’s antenna arsenal.

The Emcomm III, like all Chameleon products, is designed and made in the USA. Since they use military-grade components, you pay a premium.   The Emcomm III is one of their least expensive products at $139 US.  Is it worth the price? Absolutely. In fact, I’m thinking about buying a second one to keep in my camper.

Moreover, the Emcomm III has earned its place in my main field radio kit.  Now let’s just hope Chameleon doesn’t ask for it back anytime soon!

Note that there are actually two models of Emcomm III antennas: the Portable version ($139) I reviewed here, and a Base version ($149) which is much larger designed for permanent installation.

Thank you, Chameleon Antenna, for sending me the Emcomm III Portable for a proper field evaluation. I’d also like to thank Chameleon Antenna for agreeing to be a sponsor of QRPer.com! 

Snagging two state game lands in three days for Parks On The Air

View from Waterrock Knob on the Blue Ridge Parkway (June 13, 2020).

The following article first appeared on our sister site, the SWLing Post.

You might have noticed from recent posts, I’ve been on a bit of a POTA (Parks On The Air) kick lately.

I’ve been enjoying taking the Xiegu G90 to the field and seeing just how well it performs under intensive use on battery power. So far, it has certainly proven itself to be a capable field rig.

Still, on two recent activations I also brought my trusty Elecraft KX2 along as well.  Without a doubt, it’s still my number one field rig. It will be difficult for another field transceiver to displace it.

With that said, the G90 is less than half the price of the KX2 (when the KX2 is configured with the optional ATU). The G90 can also pump out a full 20 watts of power–nearly double that of the KX2. I also love the G90’s spectrum display which makes it so easy to find free frequencies and hunt other parks. Its internal antenna tuner–like the KX2’s–can match almost anything very quickly.

Here are a couple of quick reports from my recent activations:

William H Silver State Game Land (K-6967)

Saturday, my family had planned a trip to visit my father-in-law. My wife encouraged me to find a nearby park to activate as there are so many between our house and his. I made it slightly more challenging by deciding to find a park or POTA entity I’d never visited.

Turns out the William H Silver State Game Land was only a 30 minute detour. I had never visited it and, in fact, it was even an ATNO (All Time New One) for Parks On The Air, meaning no one had yet activated it.

I had initially planned 1.5 to 2 hours for the activation, but we were running behind Saturday morning so I had to cut my time at the park to a total of about one hour–which included set-up, operation, and take-down.

We arrived at the site and I immediately deployed my EFT Trail-Friendly end-fed antenna.

My 12 year old daughter (who is studying for her ham radio license and is a great at digging callsigns out of the noise) helped me log contacts. I stuck with very brief exchanges so that I could work as many stations as possible. When activating an ATNO, I always want to give as many POTA “hunters” as possible the best opportunity to put the site in their log books.

I started on the 40 meter band and worked 20 stations in 25 minutes with the Xiegu G90.

I then moved up to the 20 meter band and switched over to the Elecraft KX2.

Turns out, 20 meters was pretty unstable, so I worked very few stations. I did work a station in California with 10 watts and a wire, though, so I’ll still call that a success.

I plan to visit this same site again later this year–it’s very accessible.

Buffalo Cove State Game Land (K-6886)

Monday morning, even though the weather outlook was dodgy, I scheduled another park activation which, like Saturday’s, was at a state game land which was another ATNO.

I like game lands. Unlike state parks, I don’t have to worry about crowds and I also usually get to take my Subaru or truck off-road. Access roads here in the mountains are typically steep, curvy, and washed-out in places. Finding the site can be very challenging, too. Still, I love adding a little off-road fun to a park activation!

The Buffalo Cove State Game Land is much larger than park K-6967 (above). I drove deep into the lands and found a large parking and camping area for hunters. I had the whole place to myself, so I found the best tree to support my end-fed antenna.

I operated the KX2 exclusively on this activation because I wanted to use its voice keyer and my Heil headset for hands-free VOX operation.

In the course of 90 minutes, I worked 51 stations from the trunk/boot of my car.

Many thanks to my good friend Mike (K8RAT) who made the whole process much smoother by spotting me on the POTA site.

Band conditions were actually pretty rough today, so I was very pleased with the results and intend to return here for a weekend activation later this year as well. This would actually be an ideal location for making low-noise portable SDR recordings while camping overnight.

This weekend, I decided I want to increase my portable field antenna arsenal. More about that in a future post!
