On Thursday, January 6, 2022, I woke up with one goal in mind: take the Xiegu X6100 out on a proper hike-in activation!
While I’d had this radio on loan from Radioddity since December 23rd, I hadn’t had an opportunity to truly hike it into an activation site. Between the weather and my tight schedule, I haven’t had an opportunity to plot out a proper Summits On The Air (SOTA) Activation. SOTA activations that involve hiking usually take a much bigger bite out of my day and, lately, I’ve been to busy to plot one.
I do live near a vast trail network, however, and it so happens that much of the trails run through overlapping public lands: Pisgah National Forest and Pisgah State Game Land.
So I packed my Spec-Ops EDC tactical pack, grabbed Hazel’s harness, and headed out the door.
As you likely know, my activation reports typically run a few weeks behind. Although I’ve got several in the pipeline, I pushed the following report to the front of the line.
You might brew a cuppa’ coffee or tea for this one.
Here’s wishing you and yours very Happy Holidays and Merry Christmas!

A Special Holiday Activation
As mentioned in my previous activation report, we’ve spent the past week on the Outer Banks of North Carolina; specifically, Hatteras Island.
It’s been amazing.
If you’re not familiar, the Outer Banks (OBX) is a 200-mile (320 km) long string of barrier islands off the coast of North Carolina and southeastern Virginia that separates the Pamlico Sound, Albemarle Sound, and Currituck Sound from the Atlantic Ocean.
No trip to the Outer Banks would be complete without visiting North Carolina’s most iconic structure: the Cape Hatteras Light Stationin Buxton, NC.
Cape Hatteras Lighthouse
On Thursday (December 16, 2021–last week) the weather was stunning, so my family took a few long walks on the beach, explored Hatteras Island, and spent the afternoon at the Cape Hatteras Light Station which is located within the Cape Hatteras National Seashore.
Last week, my family hopped in the car and took an eight hour drive to the Outer Banks of North Carolina.
We’ve had such a busy 2021 that we decided to take a full week prior to Christmas and fit in some proper vacation and family time.
We love going to the coast off-season to avoid big crowds. Turns out, we chose well, too: it’s as is we have the whole of the Outer Banks to ourselves. Other than a couple days with some “invigorating” weather (which we actually enjoy) it’s been absolutely spectacular.
The view from our cottage
While radio plays an important role in any travels, my family time always takes priority. The good thing about activating parks is that radio and family time often go very well together!
On Friday, December 17, 2021, my daughter Geneva (K4TLI) and I decided to spend the day together while my wife and other daughter worked on an art project at our rental cottage. We had a few loose plans, but mainly wanted to fit in a nice beach walk, possibly discover some new scenic spots, and enjoy a take-out lunch together.
She very much liked the idea of fitting in a bit of POTA, so we hit the field with two sites in mind.
The plan
My Subaru is still in the body shop getting repaired after a bear decided to open the doors and make himself at home, so we have a Toyota Camry rental car on this trip. It’s been a great vehicle for sure, but its trunk space is limited and we packed quite a lot of food knowing local restaurants would be closed this time of year.
We all limited our luggage and I limited the amount of radios and gear I took. I could write an entire article about my holiday radio and antenna selection process (seriously, I put too much thought into it) but in a nutshell I limited myself to two radios and two antennas.
I’ve gotten a few messages from readers lately asking, “Why no love for the Icom IC-705?”
Looking back, I realize that I haven’t had the ‘705 in the field for quite some time (at least, in a video and field report).
Truth is, the ‘705 has been doing duty as a shortwave listening receiver in shack and just hasn’t hopped into my field pack recently. Since it’s important for the health of all field radios to soak in the outdoors on a regular basis, I packed it in my bag and took it to one of my favorite parks.
Tuttle Educational State Forest (K-4861)
The weather was beautiful on Thursday, October 21, 2021.
When I arrived at Tuttle, the first thing I did was hike their 2 mile loop to get the blood pumping.
This also gave me time to decide on the antenna to deploy: my Chameleon CHA LEFS.
During my hike I decided to do the entire activation on 40 meters only, just to get a better idea how the CHA LEFS’ propagation footprint might look with a larger sample size.
This was also the first time I’d used my N0SA paddles with the IC-705. Isn’t it cute?
Setup was quite easy.
I deployed the CHA LEFS with the feed point at about 35-40′ into a large tree.
The radiator sloped down to a point in the middle of a field and the end was elevated perhaps 4′ off the ground. I secured the end of the antenna to a length of paracord, the end of which was attached to a heavy stick on the ground, stretching the radiator.
The CHA LEFS is resonant on 40 meters, so no external ATU was necessary.
I hopped on the air, started calling CQ POTA in CW and within 10 minutes was rewarded with 10 contacts. It doesn’t get much better than this for a good start!
I continued calling CQ and, in the end, worked a total of 22 contacts in 30 minutes–almost all in CW. Check out the video below to see how it all played out.
Many thanks to KC5F and N9UNX for the Park-To-Park contacts!
Video
Here’s my real-time, real-life video of the entire activation (less antenna set up and take-down):
The QSO Map shows an interesting pattern: a ring with a few close regional stations (almost NVIS), and an outer ring of 40 meter skywave:
Thank you!
I believe one of the attractions of activating parks and summits is the fact that we really have no idea in advance how it might all play out. It’s a bit like going fishing.
I’ve gotten a lot of questions from readers lately about what propagation tools I use. In truth, my main propagation forecasting tool is my buddy Mike (K8RAT). Before I head out–or if he knows I’m hitting the field–he’ll usually text me current conditions and they’re quite accurate.
At the end of the day, though, propagation forecasts never stop me from doing an activation when I want to play radio. I just go out there and see what happens. As I’m sure my childhood fishing buddy–my Great Uncle Luther–would have said, “Any day fishing is better than a good day at work!” (Of course, a real quote from Uncle Luther would have included more “colorful metaphors.”)
A special thanks to those of you who are supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free–I really appreciate the support.
Shortly after acquiring a lab599 Discovery TX-500 earlier this year, I did what I always do: invest an insane amount of time in researching and configuring a dedicated field radio kit.
As I’ve mentioned numerous times, I’m a serious pack geek, so this is incredibly fun for me even though the choice is often difficult.
I like to buy packs and cases from manufacturers in the US and Canada when possible, so started searching through all of the options.
Requirements
The Discovery TX-500
I wanted a pack that was compact, versatile, and offered proper padding (even knowing the TX-500 is a rugged little transceiver). I don’t handle my packs with kid gloves, so I expect them to cope with sometimes rough field conditions and still protect the gear inside. I also like a certain level of organization inside the pack.
I wanted the kit to be relatively compact, but large enough to hold the transceiver, all accessories and connections, logging pad and pencil, paddles, a proper arborist throw line, portable ATU, and a 3Ah LiFePo4 battery. A the end of the day, I wanted this TX-500 field kit to be fully self-contained.
In the end, I adopted a pack with which I’m already very familiar…
The Red Oxx Micro Manager

Red Oxx is my favorite pack company and if you’ve been a reader for any length of time, you’ve obviously seen a number of their bags and packs in my field reports.
Back in 2016, when they introduced the first iteration of the Micro Manager EDC bag, they actually reached out to me–as an existing customer–knowing that I had been looking for a good radio pack with proper padding (many packs don’t require side padding and internal padding). They sent me a prototype of the Micro Manager for my feedback and then incorporated some of my suggestions.
I also purchased a Micro Manager for my wife who quickly turned hers into a mobile art studio!
She chose a red Micro Manager!Her field-ready art kit
Much like my buddy Steve (AC5F)–whose XYL creates some amazing water color art in the field–my wife (K4MOI) is also an artist and loves to paint/draw during park and summit activations. Her art kit is always at the ready and she’s traveled with it extensively over the past five years.
The Micro Manager is a pack carried over the shoulder, much like a messenger or laptop bag. Those times when my field activations require a lengthy hike, I’ve simply pulled all of the items out of the Micro Manager (since I do modular packing, this is super easy), else I’ve even been known to stick the entire Micro Manager pack into a backpack!
Over the years, Red Oxx has made iterative upgrades to the Micro Manager including a pleated front pocket, slip-in external pocket, and they started lining the internal pocket with a more flexible and thinner dense foam padding. The new padding not only fits the TX-500 better than the first Micro Manager version did, but I believe it will have enough dimension to accommodate the TX-500 battery pack when that’s available next year.
Inside the Micro Manager I also use a Tom Bihn Large Travel Tray to hold all of the TX-500 accessories: key, microphone, ATU, battery, and cables.
I own a number of these large travel trays and highly recommend them. I especially like the ballistic nylon versions for radio kits as they open and close so smoothly.
Video tour
I made a short video tour of the TX-500 Micro Manager kit before a recent activation at Table Rock:
I’ve used this pack for a number of field activations and couldn’t be more pleased. Looking back at the contents, it’s funny: the pack and almost every single item inside (save the notepad and pencil) are made in the USA while the radio is made in Russia! A bit of international harmony going on here!
If you have a field pack for the TX-500 (or any radio), I’d love to know more about it. Please consider commenting with details or even submitting a guest post with photos!
Sometimes when I’m activating a park or summit and work someone who, like me, is activating a park or summit for a Park To Park (P2P) or Summit To Summit (S2S) contact, in my head I wonder what their station and operating situation looks like on the other end.
At least one instance was uncovered recently when Dan (WB8JAY) reached out and shared a video he took while working me in a P2P contact. It’s awfully fun to hear what my signal sounded like on his end.
This video reminds me how CW distills the communications down to only those dits and dahs; unlike SSB, for example, where you might hear background noises and extra chatting during an exchange, in CW it’s just pure code.
As I’ve mentioned a number of times on QRPer and on the SWLing Post, I’m a pack geek. I enjoy organizing and packing my gear for field radio activities and travel.
Last week, I made a very quick overnight trip to visit my parents. My time during this trip was very limited and I did not plan to fit in an activation, but Monday morning, I was able to knock out an errand very early and that freed up a couple of hours in the early afternoon. Fortunately, prior to leaving my QTH, I decided to pack a few travel items in my GoRuck GR1 pack along with a field radio kit built around my Elecraft KX2.
I never leave home without a field radio kit because I never know when an opportunity to play radio might happen.
On the way home Tuesday, I popped Lake Jame State Park and fit in a quick, last minute activation. Moments before arriving at the lake, I received a request from one of my YouTube subscribers asking if I would make the occasional video showing what’s in my radio packs and field kits.
I’ve been meaning to make these videos but, frankly, often forget when I arrive at a park or summit because I’m just a little too focused on starting my activation.
Since I had some overnight items in my pack, it wasn’t a typical SOTA or POTA field kit, but I decided to make the video anyway. After all, I love watching videos about how others pack and organize their radio and travel kits. But then again, I’m a pack geek. I did mention this right–?
Although I’m not always the neatest person (my wife is probably chuckling at this gross understatement), I’m a meticulous and very organized pack geek. What you see in the video is exactly how I pack when no one is looking. 🙂
I’ll add here that if you’re interested in field radio kits and packs, I’d encourage you to check out my Anatomy of a Field Radio Kit series; Part 1 has already been published and Part 2 will be posted later this week. In Part 2, I take a much deeper dive into safety gear I take on SOTA activations.
Gear
In the video, I mention that I would attempt to link to all of the items in my pack. I spent time sorting out links this morning; many links go straight to the pack manufacturer because the packs I use typically have no distributors other than the manufacturer, I have also purchased a lot of the smaller items on Amazon, but many can be found in big box stores like Walmart, Target, Canadian Tire, etc.
If I missed something, let me know in the comments.
Video
Like all my videos, this one us unscripted, made in one take (unedited), and also has no ads:
Out of order…
So this video was made prior to an activation at Lake James last week. I’ve mentioned before that my Internet speeds at the QTH are worse than dismal, but since this pack video was relatively short, I was able to upload it ahead of the activation video (it took 1.5 days to upload this 2GB file).
The activation video will be published in another week or so depending on my access to some proper broadband service.
Any other pack geeks out there?
I would love to share photos, descriptions, and/or a video of how and what you pack for field activations. If you’re interested in submitting a guest post, please do so!
Also, I’d love to hear about your favorite packs and how well they’ve held up with time.
Feel free to comment and thank you once again for hanging out here at QRPer.com!
I had a topic on the mind as I made my way back to the trailhead after a SOTA activation recently.
I get a lot of questions from readers and subscribers about resonant vs. non-resonant antennas and whether or not an ATU is a good or bad thing.
If you know me, you’ll know that I tend to lean towards qualitative research; meaning, I like to base my opinions on first-hand observations rather than laboratory or textbook explanations. Part of the reason is I’m not an engineer, so specifications and performance stats don’t influence me–I don’t understand them half the time–rather, I base my opinions on trying or field testing.
The proof is in the pudding, right?
So with the topic of antennas and ATUs on the brain, I decided to turn on the action camera and do an unscripted video on the trail as I hiked back to my car.
This video is essentially stream of consciousness: I won’t blame you if you skip it.
With that said, if you manage to stay awake for the whole video (congratulations in advance) I’m curious what your thoughts are so please consider leaving a kind comment!
Until 2016, I had never purchased a commercial field antenna; I built all the ones I had ever used.
These days, I take a number of commercial antennas to the field and use them in my real-time videos and I really enjoy deploying and using them. My buddy Eric (WD8RIF) reminded me, though, that I hadn’t actually used a homebrew antenna in ages. He was right!
You see, while I believe commercial field antennas can be incredibly durable and compact, it’s important to note that antennas are one of the easiest components of an amateur radio system to build yourself. They require only the most simple of tools and are very affordable. And the best part? They can perform as well as those that are available commercially.
I also get a great deal of pleasure out of building things.
A simple goal
I’ve mentioned in previous posts that I often set a little goal that runs in the back of my mind for each park or summit activation I make.
On Monday, June 14, 2021, I made a simple goal: buy my antenna wire en route to Lake James State Park, build the antenna on site, and complete a valid Parks On The Air (POTA) activation.
A very simple antenna
I also decided to employ my Xiegu X5105 since 1.) it’s one of the most affordable general coverage QRP transceivers I own and 2.) it has a built-in antenna tuner (ATU).
One of the cool things about having an ATU is that, if it has the matching range, you can allow it to do the “heavy lifting” in terms of matching impedance.
Although I’d never put the X5105 to the test, I suspected its internal ATU would have the matching range to forgo building a 4:1 or 9:1 transformer and simply pair it directly with a random wire.
All I would need was a 28.5 foot length of wire for a radiator, at least a 17 foot length for a counterpoise, and a BNC to binding post adapter.
The antenna would benefit from multiple 17′ counterpoises, but I really wanted to keep this setup dead simple to prove that anyone can build an effective field antenna with a very minimum amount of components.
Even though I have plenty of wire lying around the house to build this simple antenna, I wanted to pretend I had none to prove that any wire would work.
And to add just a wee bit more challenge, I also limited myself to shopping for antenna wire between my home and the park without making a serious detour from my route. That really limited my options because there isn’t much in terms of commercial areas between me and Lake James State Park.
The wire
As I left the QTH, I decided that the best spot to shop was a Walmart in Marion, NC. It would only be a four minute round-trip detour at most. I had a hunch that Walmart would even have speaker wire which would be ideal for this application.
In my head, I imagined I would have at least three or four choices in speaker wire (various gauges and lengths), but turns out I had a difficult time finding some at Walmart. We live in such a Bluetooth world, I suppose there isn’t much demand for it these days. A store associate helped me find the only speaker wire they had which was basically a 100 foot roll of the “premium” stuff for $17 US.
While I would like to have paid a fraction of that, in the end it’s not a bad price because once you separate the two conductors, you have double the amount of wire: 200 feet.
Although the frugal guy in me cringed, I bit the bullet and purchased their speaker wire. To be clear, though, I could have found another source of wire in that Walmart, but I preferred speaker wire for this application. And $17 to (hopefully!) prove a point? That’s a deal! 🙂
Lake James State Park (K-2739)
Once I arrived on site, I found a picnic site I’d used before with some tall trees around it.
Here’s how I prepared the antenna:
First, I cut 28.5 feet of the speaker wire from the roll and split the paired wires so that I’d have two full 28.5 foot lengths.
Next, I stripped the ends of the wire and attached banana jacks I found in my junk drawer. Although these aren’t necessary as the binding post adapter can pair directly with the wire, I though it might make for a cleaner install. In the end, though, I wasn’t pleased with the connection to the radiator, so dispensed with one of the banana jacks on site, and later dispensed with the other one as well. The connection is actually stronger without the banana jacks.
I then deployed the 28.5 radiator with my arborist throw line, and laid the other 28.5 half on the ground (the ground of this antenna would pair with the black binding post, the radiator with the red post). I only needed 17 feet of counterpoise, but once it couples with the ground, I don’t think any extra length makes a difference (although less than 17 feet likely would).
The antenna was essentially set up as a vertical random wire with one counterpoise.
I then plugged the BNC binding post adapter into the rig, hit the ATU button, and was on the air.
I’ll admit: I was a bit nervous putting this antenna on the air. Although I felt the X5105 ATU *should* match this antenna, I had no idea if it actually would.
Fortunately? It did.
At this point, if you don’t want any spoilers, I suggest you watch my real-time, real-life, no-edit, no-ad, video of the entire activation (including buying and building the antenna!).
I was very pleased that the X5105 found a match on the 40 meter band.
I started calling CQ in CW and validated my activation by logging 10 stations in 13 minutes.
Honestly: it doesn’t get much better than this.
I logged three more stations on 40 meters CW, then moved up to the 30 meter band where the X5105 easily found a match.
I worked one station on 30 meters before heading back down to the 40 meter band to do a little SSB. I logged three SSB stations in five minutes.
Mission accomplished!
In the end, I logged a total of 17 stations including a P2P with K4NYM.
Not bad at all for speaker wire!
After the activation, I tested the X5105 ATU by trying to find matches on other bands–I was able to find great matches from 60 meters to 6 meters. Most impressive!
All I can say is that I’m incredibly impressed with the X5105 internal battery. This was my fourth activation from one initial charge on May 16. The battery lasted for 20 minutes, taking me well beyond the 10 contacts needed to validate this park. I’ll now consider taking the X5105 on a multiple SOTA summit run!
Short Hike
Even thought the heat was intense and the humidity even more intense, I decided to take in a 2 mile hike post-activation. I snapped a few shots along the way.
This is the Christmas Fern which derives its name from a few characteristics: its resilience to early season snows maintaining a dark green color beyond Christmas, and because folks believe its leaves are shaped like Santa’s boots or even Santa on his sleigh.
Improvements
I’ll plan to add more counterpoises to the speaker wire antenna as I know this will only help efficiency.
In addition, I’ll plan to build even more antennas with this roll of speaker wire. If you have some suggestions, feel free to comment!
Thank you for sharing this, Pete! Sadly, I was unable to attend live due to my schedule, so am very happy to see these excellent presentations. I do hope that things will be normal next year and FDIM will happen in person again. If you attend the Hamvention, I strongly encourage you to also take in FDIM–it is always an amazing event.
