POTA Field Report: Mount Mitchell State Park (K-2747) with the Mission RGO One transceiver

On Thursday October 15, 2020, my family made an impromptu trip to Mount Mitchell State Park to enjoy the amazing weather and gorgeous fall colors.

The Blue Ridge Parkway and Mount Mitchell State Park were predictably crowded with tourists, although nowhere near as crowded as the following three days which were “peak” leaf color days.

After arriving at the park, we claimed one of the little picnic areas tucked away from the crowds.  After a picnic lunch, I set up the station, my wife painted, one daughter caught up on her favorite book, and the other daughter took a deep dive in her recently acquired Yaesu FT-60R (and also helped me log).

And Hazel, predictably, slumbered.

I swear that dog is only awake maybe one hour a day.

On this particular activation, I didn’t want to deploy a wire antenna. Being the highest elevation east of the Mississippi river, the trees are short .

Instead, I deployed my Wolf River Coils TIA vertical antenna.


I consider the WRC vertical to be a “compromised” antenna especially in our region which is rocky and has poor ground conductivity. But at times like this when the park is crowded, it’s a great low-profile way to get on the air–and it’s self-supporting!  In any other year, I’m actually okay with my radio set-up being conspicuous–I love telling passersby about ham radio and Parks On The Air–but at the moment I choose to keep my social distance.

When I use the WRC antenna, I typically pair it with one of my favorite transceivers: the Mission RGO One.

I love the Mission RGO One. It’s a superb transceiver (indeed, my full review of it will appear in the November 2020 issue of The Spectrum Monitor magazine).

I like to pair the RGO One with the WRC vertical because the RGO One is capable of 50 watts of output power (the real max for the WRC), which I feel makes up for a bit of the antenna compromise. I typically start at QRP levels and increase wattage if I get no response.

At Mt. Mitchell, I rarely have internet access via my mobile phone, so I rely on the Reverse Beacon Network to spot me to the POTA network when I call “CQ POTA.”

Within a minute of calling CQ, I started logging stations. Thanks RBN!

I operated for almost an hour off and on. I took a few breaks during low activity to help my daughter with the FT-60R. At one point, she was in hysterics over a conversation she picked up on a local repeater. (Hysterics in a good way, fortunately. I do worry about some of the conversations I hear on local repeaters at times!)

Here’s my tally from Mt Mitchell:

Mt. Mitchell is one of our family’s favorite state parks and is accessible from my QTH via the Blue Ridge Parkway.

Unfortunately, the Blue Ridge Parkway is often closed during the winter, so we hope to make at least one more trip to Mitchell within the next few weeks.

I’ll add that this was the third time I’d taken the CW Morse “Pocket Paddle” to the field. It’s a brilliant set of paddles. It’s has a fantastic field-adjustable response. I’m uncertain if they’re on the market yet–CW Morse sent them to me for evaluation in the field.

I also have a set of N0SA paddles I love and typically keep packed in my dedicated MTR-3B pack.

POTA Portable, Picnic, Paddles, and Unpredictable Propagation

Practicing left hand lunching, right hand keying/logging!

It seems like lately I’ve had to work hard to log 10-15 contacts during my Parks On The Air (POTA) activations.  Propagation has been so flaky, I use every trick in the book to snag at least my ten contacts for a valid activation: change antenna configuration, run up to 40-50 watts output, employ both CW and SSB, have friends spot me on the network, and try every band possible (typically from 80-17).

Note that the majority of my activations are proper QRP and rarely do I spend longer than 60 to 90 minutes actually on the air. Indeed, many of my activations are only 60 minutes long including set-up and take-down. That may seem short to most POTA folks, but that’s what works in my schedule and family life: quick hits. It’s one of the reasons I’m not more active in Summits On The Air (SOTA)–I need more time for those sites as they’re not as accessible as our numerous POTA entities.

Still, our local star has been misbehaving, and I had not planned to do an activation on Sunday (September 28) because I saw the propagation forecast and it was rather discouraging (A index 26, SW 505, Bz -2).

From home that morning, I chased a few parks but found it challenging to hear most of them. QSB was incredibly deep–strong stations gone in an instant.

Still, my wife suggested we take a picnic to one of our favorite local spots and how could I possibly visit a park without activating it? Right–?

Zebulon B. Vance Birthplace (K-6856)

What we, as a family, love about this site is the large covered picnic area and historic log cabins. Also, the site receives very few visitors on Sundays when the main museum is closed.

Each time we visit the Vance site, we bring my MSR liquid fuel stove and make lunch/dinner.

I set up the stove, got lunch started and my wife took over food prep.

Knowing propagation was unstable, I opted for more than QRP power this time–at least, at first–so I chose the Mission RGO One transceiver (capable of 55 W output) and CHA Emcomm III Portable antenna for this activation.

I deployed the Emcomm III in a sloping configuration with the end of the 73′ radiator high in a nearby (dead) tree and the counterpoise on the ground. I also suspended the winder/balun from the corner of one of the shelter’s rafter’s with paracord.

Since it’s difficult to see a wire antenna in photos, I’ve labeled the components in the following image (click to enlarge):

I didn’t know if this configuration would prove useful, but I knew it would be better than attempting this activation with my Wolf River Coils TIA vertical antenna.

I hopped on the air starting on 80M CW (at the request of my buddy WD8RIF), worked him and three stations in rapid succession. After a few minutes of silence, I moved up to the 40 meter band and worked 16 stations. I then moved to 30 meters and worked 11 stations.

I was working more stations than I would have ever guessed beforehand.

Since I only had about 10 minutes to spare after working 30 meters, I decided to plug in the microphone and work some park-to-park contacts. While I always intend to hunt for other parks while I’m in the field, more times than not, I don’t have the luxury of an Internet connection to check the POTA spots page like I did at Vance on Sunday.

I worked 5 parks: 3 in SSB and 2 in CW.

Speaking of CW, this was my first field activation using CW Morse Double Paddles.

CW Morse recently surprised me by sending a few of their products to evaluate in the field (guessing they saw my previous post asking about keys–?).

I must say, I really love the CW Morse double paddles. They’re fully (and easily) adjustable, the action is responsive and smooth, and with the base, they’re incredibly stable on a hard surface. I highly recommend them.

At a setting like we had at Vance, I love the heavy base plate, but if I planned to hike into a site, I believe I’d remove the base to save on weight.

Unpredictable Propagation?

Perhaps there was a brief window of stability between solar events and I was able to take advantage of that while I was on the air? I’m not sure.

I never expected to log 37 contacts in the space of a little over an hour (with some of that time being off the air to help with picnic prep). Not on that Sunday when the solar numbers were in the dumps.

I’d like to believe it was a combination of things:

  • A large wire field antenna with decent gain and the ability to work multiple bands
  • 40 watts of power (at first, I backed down to QRP on 30 meters)
  • Using CW for 34 of the 37 contacts
  • Perhaps unintentionally good timing

All I know is, I had a blast! It’s hard to beat a combination of good radio, good food, good scenery, and good weather!

I suppose this was also a lesson in simply hitting the field and ignoring the propagation.

Or as Rear Admiral David G. Farragut once famously said, “Damn the torpedoes, full speed ahead!”

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! 

Initial impressions of the Mission RGO One 50 watt transceiver

On Monday, I took the new Mission RGO One transceiver to the field and attempted a POTA (Parks On The Air) activation.

I just published a detailed post including a number of RGO One photos on my other radio blog, The SWLing Post.

In short? Although it’s early days, the RGO One is a promising rig and I’m very pleased with the ergonomics, functionality, and features. It’s very well suited for field operations weighing in at only five pounds and can comfortably operate up to 50 watts if you need a little extra power. I’m looking forward to activating a number of parks this year with the RGO One!
