Because I receive so many tips from readers here on QRPer, I wanted way to share them in a concise newsletter format. To that end, welcome to QRPer Notes, a collection of links to interesting stories and tips making waves in the world of radio!
Simon’s World Map
Many thanks to reader, Mike Bott, who notes that Simon’s World Map has been updated to V1.2.3.
Did you know that there is an ever growing list of Software and Apps that allow you to practice and/or learn Morse Code using Computers, Laptops, Tablets, Android and other devices? Truly a great idea, but, if you’ve ever tried using a mouse to send Morse Code, I am sure you’ll agree that it is makeshift at best. But why?
Because It takes the right tools for the job!
To Send Morse Code it takes a Proper Built Key Or Paddle.
Now You can practice with a host of software and apps using your own device!
As I mentioned in a previous post, I do love rotating out radios I take to the field. Shuffling radios not only helps me remember a radio’s features and menu system, but it helps me understand any advantages one radio might have over another.
One radio I use at the QTH a lot is the Mission RGO One. I reviewed this radio for The Spectrum Monitor magazine, and later posted the review on The SWLing Post. It has been a few months since I posted a field report and video using this rig yet it’s one readers ask about all the time because this is a small production run radio.
Before heading out to Lake Norman State Park on August 9, 2021, I grabbed the Mission RGO One, the Chameleon CHA LEFS sloper, and my 15Ah Bioenno LiFePo4 battery. I knew this combo would serve me well as propagation that day was in the dumps!
Lake Norman State Park (K-2740)
Lake Norman is such an effortless park to activate. They’ve a huge picnic area, large trees (for both antenna support and shade!), and are typically not incredibly busy during the week. I love Lake Norman because they also have a very nice Lake Shore Trail I enjoy hiking post-activation.
That Monday morning, as I drove to the park, it was approaching lunch time and I did worry that some of my favorite picnic spots might be taken, but when I arrived, I was happy to see I pretty much had the place to myself!
Setting up the CHA LEFS sloper antenna takes a couple minutes longer than a standard end fed antenna only because the feed point is elevated and the radiator slopes down from the feed point. Since I typically do activations on my own (with no extra hands to help), I find that a little extra antenna prep equates to a quicker overall deployment.
My procedure for deploying the CHA LEFS
First thing I do is identify a good tree limb at least 45′ or so high and also identify an unobstructed path for the sloping radiator to travel.
Prior to hoisting the antenna, I stretch out the radiator and attach it to a tree or support (using the supplied paracord) in the direction I want the slope to follow.
I then use my arborist throw line to snag the desired tree limb and I connect the end of the throw line directly to the CHA LEFS’ feed point. Chameleon provides Paracord for hoisting the antenna, but the great thing about the arborist throw line is that it’s more than strong enough to handle this job. It saves the extra step of pulling paracord through the tree.
Next, I attach a 50′ length of coax (PL-259s on both ends) and stretch the coax out in the opposite direction of the CHA LEFS radiator. Doing this keeps the antenna from spinning and tangling the radiator and coax as it’s hoisted into the tree.
Finally, I simply pull the throw line and raise the antenna feedpoint to the desired height. Again, I like a height of at least 40-45′, but lower will still work. As I raise the antenna, I do put a little tension on the coax feedline just to keep it from swinging around the throw line or radiator.
Of course, if you have two people, one person can simply stretch the coax as you’re raising the antenna feedpoint which will also keep it from tangling.
In truth, the amount of extra time to deploy the CHA LEFS as opposed to, say, an end-fed half wave is maybe three minutes.
I picked the Mission RGO One because it has an amazingly quiet receiver and handles QRN like a champ. Plus, being a tabletop radio, it also sports a proper speaker, large controls, and up to 50 watts of output power if needed.
Although I’m a QRPer, on days with horrible propagation, I have been known to increase the power beyond 5 watts if operating SSB especially. This year, I set out to validate all of my park and summit activations with 5 watts or less, so at least my first ten contacts at a park will be QRP.
I thought I’d start by calling CQ on the 40 meter band in CW. Within 15 minutes, I snagged the ten contacts needed for a valid POTA activation. I was very pleased with this.
Since I had mobile phone service, I checked the POTA spots and worked AA3K (Park To Park) then moved to the phone portion of the 40 meter band.
During the exchange with AA3K, I did pump the power up to a cloud-scorching 20 watts! A proper rarity for me.
I then worked an additional five contacts in about 8 minutes in SSB. Very satisfying!
Here’s my QSO map of the entire activation. The red polylines represent SSB contact, the green are CW:
I was very pleased with the results especially after reading reports from other activators that same day who really struggled to get their ten.
Of course, I made one of my real-time, real-life, no-edit videos of the entire activation. If you’ve never seen one of my videos before and have a strong dislike of professional, well-polished YouTube channels, you’re in for a treat! 🙂
Post-activation–and despite the heat and humidity–I hiked the length of the Lake Shore Trail; roughly six miles. I highly recommend this trail if you can fit it into your schedule.
As always, thank you for reading this report and thank you to those who are supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement–my content is always free–I really appreciate the support.
Here’s wishing everyone a little radio fun this week!
FYI: I just received this announcement from Chameleon Antennas. They will be sending some samples of these antennas for me to test in the field.

INTRODUCING THE CHA POCKET ANTENNA SERIES – PRE ORDER
The CHA Pocket Series are a series of single and multi-band HF antennas that can literally fit in your pocket when not in use. There are THREE models available: a 40-6 Meter Off- Center Fed Dipole (OCFD), 40 Meter Dipole, and a 20 Meter Dipole.
This series of antennas are designed for ultra-light (all are 7 oz. or less) low power (QRP) portable operation. When running low power, an effective antenna is essential to actually making contacts – these are full-size antennas with full-size performance, but built with lightweight materials and miniaturized components. They were designed to complement the exciting new lineup of lightweight, battery operated, HF portable transceivers.
STARTING TO SHIP AT THE BEGINNING OF SEPTEMBER 2021
Many thanks to Don (W7SSB) who shares the following news from Chameleon Antenna:
WE’RE MOVING TO A NEW LOCATION!!
In August 2021, we will be at our NEW location, South of the airport in Sparks Nevada! The NEW location will be TWICE the size of the current one which will allow us to hire more people, increase production & inventory thus allowing us to ship faster!
Here in the Asheville, NC area, there’s one mountain that almost anyone can recognize by sight: Mount Pisgah.
Mount Pisgah is prominent because not only is it one of the taller summits bordering the Asheville basin, but it’s also home to the WLOS TV tower and and a cluster of public service and amateur radio repeaters.
I’ve been eager to activate Mount Pisgah for Summits On The Air (SOTA). Along with Bearwallow Mountain, and Mount Mitchell, it’s one of the most popular SOTA summits in the Asheville area.
Being so accessible from the BRP, the Mount Pisgah trail also receives a heavy amount of foot traffic. Being locals, our family tends to skip this trail when we’re venturing along the BRP because it can be so congested at times.
Mount Pisgah (W4C/CM-011)
On Tuesday, June 1, 2021, Hazel and I decided to hit Mount Pisgah fairly early and avoid the crowds.
We arrived at the trailhead around 8:15 AM and there were very few cars there–a good sign indeed!
Hazel was chomping at the bit to start our hike!
The trail is only about 1.5 miles with a 700 foot elevation gain, so not strenuous.
It was blissfully quiet and we only passed two other groups of hikers on the way up.
I’ll admit that I was keeping an eye out for black bears, though. We saw bears very close to the trailhead entrance on the BRP that morning. I may have mentioned before that black bears are not something to be feared here in western North Carolina; they typically avoid people and your chances of being fatally injured by a black bear are incredibly slim–right there with being struck by lightening.Still, the black bears that wonder near populated spots like Pisgah along the parkway are often fed by tourists and lose their fear of humans. Not only that, but they even expect people to be food dispensers. Not good. As we say around here, “a fed bear is a dead bear” because feeding bears leads to aggressive behavior and the poor creature’s eventual euthanization.
But I digress!
Hazel and I reached the summit and were happy to find that we were alone. Pisgah’s summit can get very crowded as there really isn’t a lot of space–only a large viewing platform next to the massive tower.
When we arrived on site, the summit was surrounded in clouds.
I briefly considered operating from the viewing platform, but knew I would have to cope with a lot of curious hikers while trying to operate CW. Since I’m not a good multitasker, I decided to do what many SOTA activators do: carefully pass under the tower and find an activation spot on the other side of the summit.
Hazel and I found a small overgrown trail used primarily by those working on the tower. I deployed my station in a small clearing.
For this activation, I chose my Elecraft KX2 and paired it with the Chameleon CHA MPAS Lite which has quickly become one of my favorite SOTA antennas.
I deployed the CHA MPAS Lite perhaps 15 feet away from my operating spot, in the middle of a spur trail. I was able to extend the 17′ vertical without touching any branches. I rolled out about 20-25′ of counterpoise wire along the ground.
After setting up, it dawned on me that I’d forgotten my clipboard. No worries, though! I simply flipped over my GoRuck GR1 pack and used the back as an operating surface.
On The Air
Not only was this a summit activation, but also a park activation–indeed, a two-fer park activation at that! The summit of Mount Pisgah is in both Pisgah National Forest (K-4510) and Pisgah State Game Land (K-6937).
If I’m being honest here–since I’m not a “numbers guy” and don’t follow my activation counts closely each year–it’s very tempting not to announce or count this activation in both the SOTA and POTA programs since K-4510 and K-6937 aren’t rare entities. The main reason for this is because, back home, I end up doing double entry with my logs: loading them via the SOTA online log submission tool, then entering them in N3FJP or TQSL for submission to the POTA and WWFF programs. It can be very time-consuming doing this.
I am working on a way to “massage” the ADIF file data so that I can submit it to both programs with less effort.
But, of course, I announced the activation on both SOTAwatch and the POTA site. At the end of the day, I’ve never *not* announced a dual SOTA and POTA activation because I can’t help but think it might offer up the sites to a new POTA hunter. It’s worth the extra log entry later.
Another plus with activating a site in two programs is that you’ll likely be spotted in both thus increasing your odds of logging the necessary contacts to validate your activations.
Turns out, snagging valid activations that Tuesday morning was incredibly easy. And fun!
I started on 20 meters CW and logged fifteen stations in eighteen minutes. The band was energized because not only did I easily work stations from France, Slovenia, and Spain in Europe, but also stations all over North America from the west coast to as close as the Ohio valley and into Canada.
I wanted to play a little SSB, so I moved to the phone portion of 20 meters and spotted myself on the SOTA network. I worked five stations in eight minutes. Fun!
Next, I moved up to the 17 meter band and stayed in SSB mode. I worked five more stations in nine minutes. Had I only activated this site in SSB on 20 and 17 meters, I could have obtained both a valid SOTA and POTA activation in 17 minutes.
Even though I knew I needed to pack up soon, I decided to hit the CW portion of 17 meters before signing off. I started calling CQ and was rewarded with sixteen additional stations in eighteen minutes.
All in all, I logged 41 stations.
Here’s the QSO Map of my my contacts–green polylines are CW contacts, red are SSB (click to enlarge):
A welcome interruption!
If you watch my activation video, you’ll note that as I moved to the 17 meter band and started calling CQ, another hiker popped in and introduced himself.
Turns out it was Steve (WD4CFN).
As Steve was setting up his own SOTA activation on Mount Pisgah next to the observation deck, his wife, Patty, heard my voice off in the distance giving a signal report.
Steve and I had a quick chat and coordinated frequencies so we wouldn’t be on the same band at the same time and interfere with each other.
After finishing my activation, I stopped by the observation deck and spent some time with Steve and Patty as Steve finished his SOTA activation and packed up his gear.
Steve was also using an Elecraft KX2 and strapped his telescoping fiber glass mast to the side of the observation deck to support a wire antenna. Very effective!
Hazel and I hiked back to the trailhead with Steve and Patty. It was so much fun talking ham radio, QRP and SOTA with kindred spirits. What an amazing couple!
Steve and Patty were actually on a multi-day camping trip in WNC and planned to hit two more summits by end of day. In fact, I got back to the QTH *just* in time to work Steve (ground wave!) at his second summit of the day. It was fun hunting someone I had just spent time with on a summit!
Steve and Patty: Again, it was a pleasure to meet you both!
Hazel and I both needed a little trail time that Tuesday morning. Hiking to the summit in the low clouds, taking in the views, enjoying a stellar activation and then meeting new friends? It doesn’t get any better than this.
I’ll say that I do love the Elecraft KX2 and CHA MPAS Lite combo. It makes for a compact and effective SOTA pairing that can be deployed so quickly.
A couple months ago, I ordered a SOTAbeams Tactical Mini fiberglass telescoping pole. I plan to pair it with my QRPguys tri-bander kit antenna.
If I’m being honest, though, I find that the CHA MPAS Lite is so quick to deploy–like 2-3 minutes tops–I’ve yet to take the Tactical Mini and Tri-Bander to a summit. No worries, though, as I will eventually deploy this pair on a summit. Admittedly, I need to work on my mast guying skills in advance–let’s just say that I’m still in that awkward stage of struggling to manage each guy line as I try to keep the Tacmini vertical during deployment. I welcome any tips!
Last time I visited Table Rock Fish Hatchery–this activation–it was a struggle to get the ten contacts I needed for a valid activation. Propagation was horrible that day, making it a proper struggle.
On Thursday, May 20, 2021, I thought I’d go back to the fish hatchery for another try! I really like the site: it’s open, has lots of trees, and the staff (and neighborhood dogs) are all very friendly.
Thing is, as I drove to Table Rock, my buddy Mike informed me that propagation took a nose dive. Earlier in the day, it had been reasonably stable, but he noted that POTA activators were struggling in the afternoon and the propagation numbers were in the dumps.
My secret weapon: The Chameleon CHA LEFS
Shortly after I posted my “unboxing” video of the lab599 Discovery TX-500, Carl at Chameleon Antenna made a comment on my YouTube channel that he was going to send me their CHA LEFS (Lightweight End Fed Sloper) wire antenna since it’s resonant on 40, 20, 17, 15, 12 and 10 meters. In many ways, it’s ideally suited to pair with the TX-500 since this transceiver lacks an internal ATU. Side note: there is a cool project in the works called the DIY599 that adds a 60 watt amp and ATU to the TX-500 .
I had only recently received the CHA LEFS and had not yet taken it to the field. Table Rock was the perfect opportunity.
When I know in advance that propagation is poor, I try to make my portable set up as efficient as possible, so that’s when I 1.) make sure I pull out a resonant wire antenna and 2.) use a wire antenna with longer radiators. The CHA LEFS fits both of these bills.
The CHA LEFS has a 63 foot radiator made of 20 gauge PTFE antenna KEVLAR wire. The winder has a large efficient transformer to match impedance, and there is an inline coil to make the most of the 63′ radiator. They also include 50′ of Micro 90 paracord.
Like all Chameleon antennas I’ve used, it’s built to military specs.
Table Rock Fish Hatchery (K-8012)
Table Rock is ideally-suited for a long-ish sloping wire antenna, too. The site has tall trees and open spaces that make stretching out the sloping radiator quite easy. Just watch those power lines!
The CHA LEFS takes longer to deploy that end-fed antennas with a feedpoint near the ground. I find it quicker to deploy, however, than dipoles.
I deployed the LEFS by first stretching out its radiator wire in the direction I planned to deploy it.
Next, I connected the coax feedline to the SO-239 on the LEFS winder and stretched it in the opposite direction of the radiator. Why do this? It helps keep the radiator and coax from twisting together as I raise the winder/feedpoint into the tree.
This is not a difficult antenna to deploy as one person. Of course, if you have a helper, it’ll go even faster (I’ve yet to convince Hazel to help me with antenna deployment).
I had launched the arborist line quite high into a tree at the picnic table where I planned to operate. I was able to elevate the LEFS feedpoint/winder about 47′ into the tree.
I used the supplied paracord to attach the radiator to a nearby branch. The end of the sloper was perhaps 6 feet off the ground (if memory serves).
Knowing how poor conditions were from real-life K8RAT observations, I didn’t expect to actually validate my activation by logging the required 10 contacts. As I stated in my activation video, I was fully prepared to walk away with three or four contacts–I didn’t have a few hours to burn on an activation. I was simply happy to play with a new antenna, the TX-500, hang with the local canine welcome committee and enjoy the fine weather.
First, I hopped on 40 meters and discovered the LEFS provided a perfect 1:1 match on 7063 kHz. Very promising!
Next, I started calling CQ and the Reverse Beacon Network functionality of the POTA spots page must have quickly auto-spotted me.
Within 13 minutes, I logged six contacts! I was impressed. Mike (K8RAT) was in that first six contacts and he later told me it was one of the strongest signals he’d ever heard from me at a POTA activation. He asked what I was using as an antenna that day and said, “it was working!”
Next, I moved to the 30 meter band and worked K8RAT again (a rarity on 30 meters!) along with four other stations.
I ran out of time, so called it quits with 11 stations logged.
I did not expect to not only walk away with a valid activation, but to have completed it in such short order.
Here’s the QSO Map of my contacts all made with 5 watts of power:
As Carl suggested, I’m going to keep the CHA LEFS tucked away along with my PackTenna EFHW in the Discovery TX-500 pack.
When conditions are poor, I’ll spend the modest amount of extra time deploying this fine antenna.
The only CHA LEFS criticism I noted–and it’s a minor one–is that the in-line trap/coil isn’t very low-profile and takes a little attention to make it fall in the right spot when reeling the antenna up post-activation. Seriously. A minor criticism and I’m guessing Chameleon has a reason for it being on the large size–likely for power handling reasons.
Field Day is coming up, and I think I’m going to make the CHA LEFS one of Team Baklava‘s main antennas (Team Baklava = my buddy N3CZ and me!).
It’s actually quite odd that I’ve never activated this park during the weekly trip to do a little caregiving for my folks: Crowder’s Mountain State Park is a reasonable detour especially compared to some of the more remote parks I’ve visited recently.
What’s really impressive about Crowders Mountain is that although it’s not as large as a national park and it’s very close to the city of Gastonia, it has no less than two unique summits that qualify for Summits On The Air: The Pinnacle and Crowders Mountain.
Both summits are accessible from the main park visitors’ center via a well-maintained trail network.
The propagation forecast looked pretty grim and after my last activation, I thought I might increase my chances of success by hiking to both summits in one visit. This made sense because I would only need 4 contacts per summit to have a valid SOTA activation and I could combine the contacts from each summit to hit 10 total contacts to activate the state park.
I decided to call the park and ask how long it would take to hike to both summits: the ranger told me “about 5 hours, or less if you’re fast.” That meant that once I added in my setup/pack up times and on-the-air time, I would be staring at a minimum of 7-8 total hours.
I (wisely) decided to pass on that opportunity. I simply didn’t have enough time in my schedule for that many hours at the park. That, and I didn’t want to feel rushed–I wanted to enjoy my outdoor time.
I decided instead to activate one summit and simply plan on spending more time on the air then plan to come back to the park for the second summit on a different day.
Before going to bed Monday night, I checked out the trail map and decided to activate The Pinnacle.
Crowders Mountain State Park (K-2726)
I arrived at Crowders Mountain State Park around 11:00 AM local–the weather was nearly ideal.
I had pre-packed all of the radio gear and supplies in my GoRuck GR1 rucksack, so once I arrived, I grabbed the pack, put on my hiking boots, a hat, and hit the trail.
I’ve read that Crowders Mountain State Park can get very busy and it’s no surprise as the park is within easy reach of Shelby, Gastonia, and the Charlotte Metro area. Fortunately, I was visiting on a Tuesday morning, and while I saw at least 30+ cars parked in the main parking lot, I passed other hikers only a few times on the Pinnacle trail. It’s a sizable park and can easily swallow 30 groups of day hikers!
I followed the orange-blazed trail to the summit of The Pinnacle.
The hike was very enjoyable and, frankly, not what I would consider strenuous, but it had enough elevation change to feel like a proper hike. I allowed an hour to reach the summit, but it only took about 40 minutes or less.
Near the summit, there’s a fork in the trail: if you take a right, it leads to the summit, if you take a left, it’ll lead you on a much longer Ridgeline Trail that will eventually take you into Kings Mountain State/National Park–you’d better believe I’ll try that one day in the future! It would be fun to activate two parks and a summit all on foot.
I took a right at the fork and the .2 mile long trail zig-zagged up the side of The Pinnacle.
I was a little surprised to be greeted by the sign above. It’s true that the summit area is quite rocky and you have to watch your step, but this warning is a bit extreme in my opinion (especially since the SOTA activation I did with my daughter recently was orders of magnitude more dodgy!).
If you are activating The Pinnacle and don’t want to climb up the rocky path, no worries. I’m certain the area where the sign is located is well within the SOTA summit activation zone.
The Pinnacle (W4C/WP-010)
Although The Pinnacle is only a “one point” summit, when you reach the top you’re greeted by some impressive views.
The Pinnacle and Crowders Mountain are both outlying mountains so are the tallest points in the area offering beautiful, long-range vistas.
There were perhaps a half dozen hikers hanging out on the summit. I found a quite spot to set up on the side of the summit only a few meters from the top.
During the hike, my buddy Mike (K8RAT) sent a text noting that propagation on 40 meters was non existent. He suggested I play on 20 meters and above, possibly including 30 meters.
Later on, I found out that Mike was 100% correct. Several POTA activators that day mentioned on the POTA Facebook group that 40 meters was completely wiped-out.
I installed the Chameleon MPAS Lite vertical antenna next to me. I’ll admit that I was a little worried it might be too rocky to plunge the MPAS Lite’s stainless spike in the ground, but it turned out not to be the case.
The CHA MPAS Lite has really proven itself as an invaluable SOTA antenna. While the stainless spike adds weight to my pack, it’s less fussy than dealing with guy lines and telescoping fiberglass poles and much quicker to set up. You do need enough ground to plunge that spike into, but if there are trees and bushes on the summit, it’s probably doable!
I started recording a video (see below) of the activation, spotted myself to the SOTA network (even though it would have likely auto-spotted me via the Reverse Beacon Network) and hopped on 20 meters.
I had no idea at the time, but we were experiencing a solar flare which explained why 40 meters was completely wiped out.
The effect on 20 meters was simply epic.
I called CQ and was instantly rewarded with a long, continuous string of stations. Within 26 minutes, I had already worked 23 stations with 5 watts and the MPAS Lite vertical. A stark contrast to my previous POTA activation.
And here’s the thing: the flare opened up 20 meters to local/regional stations as well. I worked stations as close as South Carolina, Georgia, and Tennessee–this is simply unheard of normally. Of course, stations on the west coast were also booming in.
I was a little surprised I didn’t log any European stations on 20 meters, but I suspect they were having a difficult time competing with the strong signals from North America during the flare.
I short: the band opening was amazing fun and even renewed my faith in our local star just a wee bit. (Ha ha!)
After playing on 20 meters, I decided to try 17 meters.
Wow! Without a doubt, I worked more stations on 17 meters in short order than I’ve ever worked during a field activation. In 10 minutes, I worked 12 stations. As with 20 meters, the flare opened up stations that would normally be in my 17 meter skip zone.
Here I was worried about logging the ten stations needed to validate my park activation! After logging 35 total contacts, I decided to pack up.
Here’s a QSO Map of the activation (click to enlarge):
Here’s one of my unedited real-time, real-life videos of the entire activation:
Although the weather app on my phone wasn’t showing any afternoon thunderstorms nearby, there were some patchy dark clouds forming on the other side of the summit and the winds were shifting, so I decided to call it a day and enjoy the hike back down the mountain.
Fortunately, the clouds never amounted to anything but I don’t take my chances with spring weather–it’s fickle, especially along the North Carolina/South Carolina line. That, and frankly, I needed to stick to my travel schedule.
I took my time on the way back down and simply soaked up the outdoors.
I love doing field activations of all types, but I’ll admit that I’m becoming addicted to Summits On The Air because of the hiking opportunities it presents.
There are few things in the world I enjoy more than hiking.
When I’m on a trail, all of my concerns seem to dissolve.
On the return hike, I passed by a group of three hikers. All of them were staring at their phones while hiking and one tripped on a tree root in the path. They caught themselves before hitting the ground.
I’ll admit I was thinking at the time that mother nature was saying, “Hey! Wake up, disconnect and enjoy the beauty around you! You need some perspective!” 🙂
I’m already looking forward to visiting Crowders Mountain State Park again. I believe I’ll return within a month and hike to Crowders Mountain, activating both the summit and park.
Sometime, I’d like to hit the trails as soon as the park opens and, perhaps, activate both Crowders Mountain and Kings Mountain parks on foot. That would likely take an entire day when I include the time on the air, but it would also be a lot of fun.
I was telling my wife yesterday that I actually enjoy writing up the odd field report on QRPer. It hit me that there are a couple of reasons why…
For one, a number of readers have reached out and thanked me because they enjoy living vicariously through my field reports and videos. I get it. My family and I enjoy watching YouTube videos of travelers around the world. We avoid the personality-driven channels and focus more on those that are less “produced.” It gives us an opportunity to travel to, say, Spain, France, Finland, or Turkey when we can’t presently do so. It pleases me to no end thinking that my reports and videos could, even in some very small way, offer a little vicarious travel to others.
Secondly, writing up these reports gives me an opportunity to re-experience some of my field time and sort through photos I might have taken along the way. Although it takes a few hours to write a report, I truly appreciate the experience.
Thank you, dear reader, for spending time with me during this outing!
I just received an email announcement from Chameleon Antenna, and I thought I’d share it here.
I’ve often referred to Chameleon antennas as “military-grade” because I’ve seen numerous military portable antenna systems over the years and Chameleon antennas are engineered to that standard. The quality is simply uncompromising.
Chameleon antennas are at the top of the amateur radio price bracket for portable antennas, but affordable compared to other military field antenna systems.
Their recent email announcement showcased a real-world example of how their antennas are used in military communications exercises. From Chameleon:
For QRPX 2021, the NTC Operations Group, Fort Irwin, CA station had the opportunity to deploy several Chameleon Antenna systems to use in the competition. This article is a summary of how each system performed during the contest, and how each could serve a military operator best.
Every year in mid-March, Army NETCOM hosts an annual HF Low Power Competition where stations across the globe try their best to establish HF communications with each other over a variety of modes, including USB Voice, ALE, 3rd Generation ALE, and Tactical Chat messaging application.
Active Duty, Reserve, and National Guard elements of the US Army
The three Army MARS HF Hubs in Ft. Detrick, MD; Ft. Huachuca, AZ; and Ft. Shafter, HI
Any other military branches including Air Force, Marines, Navy, Space Force, and Coast Guard
Canadian military teams
Army MARS Auxiliarists
As a Signal Coach out here at The National Training Center (NTC), Fort Irwin, CA, I found out about this competition, and competed the last two years. In the 2020 QRPX, I operated my station alone using only an L3Harris AN/PRC-150 with its accompanying antenna, the L3Harris RF-1944 dipole kit. I operated as I was able to, not expecting much, only to find out that my station placed third with 48 points and was only a few contacts shy of the winning score of 53 set by a fully stacked team from Joint Base Lewis-McChord. I was absolutely hooked from there.
I’d recommend you download and read the detailed report.
If you can’t tell, I’m proud to have Chameleon Antenna as a sponsor of QRPer. They’re a brilliant company that designs and builds all of their gear here in the USA. Their gear is built for the long haul. They’ve never heard of the marketing concept “planned obsolescence.” I’m guessing Chameleon’s idea is to impress you enough with their product quality that you buy more and more of their systems.
By the way, if you think I’m supportive of amateur radio manufacturers that build quality products, don’t even get me started about my obsession with US-made backpacks and camping gear. Seriously. Just slowly back away while you can… 🙂
Chameleon Antenna has sent me a number of their antenna systems to evaluate in the field over the past few months at no cost to me. I appreciate not only the opportunity to test these antennas, but to provide the company with my frank feedback.
As I’ve mentioned previously, Chameleon antennas are military grade and build here in the US (check out Josh’s tour of their factory). You pay a premium price–compared to imported options–but their gear is built for performance, easy deployment, and longevity.
What has impressed me most about Chameleon gear is how flexible and modular it is. Their antenna systems are adaptable to almost any situation and always built around the idea of emergency communications.
Recently, Chameleon sent me their new CHA TDL or Tactical Delta Loop antenna. This vertical loop antenna has been designed to be portable, and tunable from 3.5 to 54.0 MHz (80-6M), but, as Chameleon points out, “is most effective on the bands from 10.1 to 54.0 MHz (30-6M). ”
If I’m being perfectly honest, I wasn’t sure what to expect this antenna to look like–in terms of size–once deployed, so I set it up in the front yard prior to taking it to the field.
Set up couldn’t have been more simple: attach the 17′ telescoping whips to the stainless steel spike (with one whip attached to the Hybrid Micro), extend the whip sections, then attach the loop wire to connect the tips of both whips.
It might have taken me four minutes to set up the TDL on the first go.
This antenna needs a little space for sure: this isn’t one you could easily deploy in a dense forest, but it has a very flat profile vertically. I can’t think of a single park I’ve activated that couldn’t accommodate the CHA TDL.
I like to try to give gear a fair chance when I do evaluations and thought I’d wait until propagation was at least stable before taking the TDL to the field and making a real-time, real-life video (as I used it for the first time). But, frankly, I’m way to impatient to wait for the sun to play fair! Trial by fire…
Lake Norman State Park (K-2740)
On Monday (March 15, 2021) I packed up the CHA TDL and headed to Lake Norman; one of my favorite parks to play radio.
Propagation left much to be desired that afternoon, but the weather was perfect.
I decided to pair the CHA TDL with my Icom IC-705. Since the CHA TDL requires an ATU, I connected the mAT-705 Plus.
NVIS on the low bands
I had no idea what to expect from the CHA TDL in terms of performance, but Chameleon notes that it provides Near-Vertical Incidence Skywave (NVIS) propagation on 40 and 80 meters. NVIS antennas are very popular for the military and for emergency communications since the propagation footprint is much closer to home than it might normally be.
NVIS is also a brilliant option for park and summit activators, especially if they’re activating in an area with a high density of park/summit chasers. For example, if you live and activate sites in the state of Maryland, employing a NVIS antenna might make your site more accessible to the DC metro area, Pennsylvania, Virginia, New York, Delaware, and New Jersey–regions that might otherwise be in the skip zone of your 40 meter signal.
On the air
Operating five watts CW, I started calling CQ POTA on 20 meters and snagged four stations in about seven minutes.
I was very pleased to work a station in California and one in Montana with five watts. (Though I need to check, this might have been my first MT station logged from a park.)
Next, I moved to 40 meters and was very curious if the TDL would provide me with proper NVIS propagation.
It did! One litmus test for me is when I work stations in Tennessee on 40 meters. Typically, I only log TN stations when on 80 meters or when I’ve configured one of my wire antennas for NVIS coverage.
Here are my logs from this 28 minute activation:
Here’s a QSOmap of the activation–the delineation between my four 20 meter contacts and eight 40 meter contacts is pretty evident:
In a future video, I’ll show how I deploy the CHA TDL.
Unfortunately, I left my tripod at home, so apologies for the viewing angle as I operated the IC-705.
This first test of the CHA TDL really couldn’t have gone better.
I was able to easily deploy it on sloping ground, among trees, in a state park, and snag both locals and QRP DX within a brief window of time on the air. All this, while our local star tried its best to interfere.
In terms of construction, the TDL is what I would expect from Chameleon: military grade.
For park activators and Emcomm purposes, the CHA TDL makes for a convenient, portable NVIS antenna on 40 and 80 meters.
While I have lighter, smaller footprint antenna options for SOTA, I must admit I’m very curious how it might perform on 20 and 17 meters from the summit of a mountain. The idea of being able to rotate the antenna and change the propagation footprint is very appealing. I’ll save this experiment for a summit that doesn’t require hours of hiking, though, and one where I know I can jab the stainless steel spike in the ground (i.e. not on top of a rocky mountain).
Any negatives? When I first deployed the TDL at home, we were having 30+ MPH wind gusts. When the gusts shifted, it did move the antenna. This could be remedied pretty easily by using a bit of fishing line filament to tie off one side of the loop. With that said, I’m not sure I’d configure the TDL as a loop if I expected strong winds. Also, as I mentioned earlier, this might not be the best antenna to pack if you plan to include a multi-hour hike in your activation.
And herein lies the brilliant thing about Chameleon Antennas: If I packed in the CHA TDL and found that winds were strong on site, I would simply configure it as a vertical instead of a loop!
The CHA TDL can easily be configured as a CHA MPAS Lite portable vertical: all it’s missing is a counterpoise wire which you can buy separately from Chameleon or, better yet, just use some spare wire you have on hand!
Or, you could configure it as a random wire antenna by directly connecting a length of wire to the Hybrid Micro transformer.
That’s the thing about Chameleon HF Antennas: they can be configured so many different ways.
If you’re interested in the CHA TDL, I’d strongly encourage you to read though the user manual: it’s chock full of info and ideas. Click here to download as a PDF.
Next time I take the CHA TDL out, I think it’ll be to a summit where I’d like to see how it might perform on the higher bands with the ground sloping away from the antenna site.
On Monday, March 8, 2021, I had a very rare opportunity: nearly a full day to play radio!
I debated where to go the night before and I had a lot of ideas. Do a multi-park run? Activate some new-to-me parks a little further afield? Hit a SOTA summit?
While it was very appealing to plan a multi-park run for POTA/WWFF, I really wanted to stretch my legs and activate a summit. The weather was glorious and it dawned upon me that we’ll soon be entering the season of afternoon thunderstorms which will, no doubt, have a negative impact on my summit plans for the next few months since afternoons are typically when I have time to do activations.
After examining the map, I decided to go to Elk Knob State Park. The summit of Elk Knob is a SOTA site and the park is in both the POTA and WWFF programs.
When people tell me running QRP is like “trying to play radio with both hands tied behind your back” I’ll show them this video. 🙂
While the hike, the weather, and the signals were all in my favor, I’ll admit I wasn’t on my “A Game” that day. We all have days like this where we struggle to copy, to keep up with the flow of contacts, and to send correctly.
In recent weeks, I’ve gotten a number of emails from readers and viewers who said they had a less-than-smooth SOTA or POTA activation and felt a wee bit embarrassed on the air when they struggled copying.
But you know what?
This is all about having radio fun in the field, enjoying a hike, taking in the views, and soaking up the beautiful weather! It’s not a contest and we have nothing to prove to anyone.
I can also promise you that any chaser/hunter who has ever activated a field site will completely understand if they have to send their call a couple extra times or if they (heaven forbid!) have to re-send their call after you incorrectly copy a character.
This is totally normal.
Be easy on yourself and enjoy the ride. Even on days when I don’t feel like I’m 100% in the groove, I find doing a summit or park activation clears my mind and resets my soul.
My policy? When a mistake is made laugh it off and move on!
