Picture this .. you are getting a bit twitchy due to lack of POTA activation and you have run out of Potaxxia. Further, You publicly stated a New Year’s eve goal to make at least 200 POTA CW activation contacts per month for 2023 (there may have been beer involved), and now you must stay accountable to your goal and you are currently behind plan. It’s too early in the season to be lawn mowing while listening to podcasts such as QSO Today, Ham Radio Workbench, ICQ Podcast, AP/DZ or Soldersmoke. Thus, chasing contacts is [always] a good use of your time.
Lastly, if you are like me, the the solar indices are still an art form being learned and the numbers for today aren’t all in the green zone.

So you begin to wonder just how much effort it’s worth to load up your gear and try to activate. You think to yourself that there won’t be much action on bands other than 20m which has been noisy lately, so why bother as it’s at least a 45 minute trip to the nearest POTA entity.
With this background, on Saturday I placed myself in the city at the nearest-to-home spot I could park in the south part of Calgary adjacent to VE-5082, the Trans-Canada Trail. I was trying to make the best of what I perceived to be a rough conditions day and had no real plan except a convenient location requiring minimal effort for a minimal return. My expectations were, sadly, met in this regard.

I was at the edge of suburbia with large homes on my left overlooking the ravine and pathway on my right. To say it was RF noisy would be a colossal understatement. I made 18 painful contacts in an hour and I’m sure people called me but I didn’t hear them given the S7 noise floor on 20m. At least I made one DX contact to Denmark along the way. Overall feeling frustrated, I went back home.
Sunday morning rolls around and again I wonder “is it worth it”?

The Visitor Center at Kinzua Bridge State Park (K-1366) is well worth a visit. It provides an excellent overview of the history, use, and collapse of the railroad bridge that gave the park its name, and it provides an excellent view of the pedestrian skyway built on the portion of the bridge that remained standing after the tornado that caused the collapse.
Reflections on Activating a Not-so-New Park
by Brian (K3ES)
Monday, April 3 was one of those beautiful, warmish (60ºF or 16ºC) sunny days in northwest Pennsylvania that remind us that spring is really here. Only a week earlier, we had an unexpected snow fall that covered the ground (and it will likely not be our last snow of the season). So my wife, her father, and the dogs all looked forward to getting out of the house to enjoy the weather. We packed for a picnic, and drove through bright sunshine to Kinzua Bridge State Park.
After a picnic lunch, and while Becky and her dad explored the visitor center and walked the dogs, I set up for a Parks on the Air (POTA) activation of K-1366. This would be my first activation of the park, but not my first visit. I have been there several times before, including an excursion trip behind a steam engine that took me across the railroad bridge over Kinzua Creek and back.
A view from the visitor center of the pedestrian skyway. It was constructed on the structure that remained after the bridge was struck by a tornado in 2003, causing its partial collapse.
An Historic Park
Kinzua Bridge State Park has an interesting history. The railroad bridge that gives the park its name was originally built of wrought iron in 1882. At the time it was built, the 301 ft (92m) high and 2052 ft (625m) long railroad bridge was the highest in the world. It was rebuilt in place in 1900, replacing iron with steel, to strengthen it for the heavier trains that needed to cross. The bridge remained in commercial service until 1952, and was later sold to the Commonwealth of Pennsylvania for a State Park. The bridge continued to support excursion trains and pedestrian traffic until 2002, but was struck by a tornado in 2003, causing its partial collapse. Today, the remaining part of the bridge has been rebuilt as a pedestrian skyway, complete with a glass floor at its end to look down at the valley far below.
The visitor center provides an excellent multimedia overview of the economics, technology, and history of the structure. It is well worth a visit. Similarly, the skyway gives a spectacular view of the structure, the collapsed towers, and the surrounding Pennsylvania forest. The park has picnic facilities and hiking trails, and a trailhead for the rail trail that has repurposed the old railroad right-of-way.
This is a view of the picnic pavilion from my operating position. The picnic area also has a number of other open picnic tables and a playground area for the younger crowd.
The Setup for Activation
I stopped into the visitor center to let the staff know of my intention to activate. I found them to be friendly and accommodating, which always makes activating a pleasure. I do my best to be a good ambassador for amateur radio and the POTA program.
For activating, I set up at a remote picnic table. Three tosses got the throw line over a good branch to support my Tufteln 9:1 random wire antenna. A 15 ft RG-316 cable connected the antenna to my Elecraft KX2. Completing the station were a 3 Ah LiFePO4 battery, a set of generic earbuds, and VK3IL pressure paddles. I used a clipboard to keep my notepad from blowing around in the breeze, while I logged with a mechanical pencil.
The picnic table operating station used to activate K-1366. Included are the KX2, VK3IL pressure paddles, clipboard and log.
The Activation
As I finished getting the station ready to go, it occurred to me that I had a frequency-agile-antenna and rig, a bit more than an hour to operate, and no other operators in the area. So, I took the opportunity to try for contacts on as many bands as possible, inching my way toward the POTA N1CC Activator award for making contacts on 10 bands from 10 parks. The park has good cell coverage, so I was able to use my phone to spot myself. After that, I mostly left things to the Reverse Beacon Network and the POTA spotting gateway, but I was able to use the phone to confirm that my changes in frequency were picked up.
In 70 minutes of CW operation at 5 watts, I made total of 26 contacts, including at least one contact each on the 10, 12, 15, 17, 20, 30, and 40m bands. An apology to the hunters may be in order, because I was harder-than-usual to contact. After making a contact on each band, I would QSY to the next at the first significant lull in the action. I look forward to another trip back to K-1366 to try for contacts on the 3 additional bands needed to complete its activation toward my N1CC.
As you might guess, by using multiple bands, the contacts came from both far and near: as far as Spain to the east and Oregon to the west, and as near as New York, Pennsylvania, Ohio, and Michigan. Middling distances were also well represented in the log.
It was a good day in the park, and here is the contact map from a 7-band activation of K-1366.

This outing made for a fun and productive afternoon that was all the more enjoyable for sharing it with my family.
It also made for a great opportunity to shake off the winter blahs, and it held the promise of beautiful spring and summer days for more park activations.

Here is a bonus picture of another semi-famous bridge in northwestern Pennsylvania (it actually has its own Facebook page). This is Nebraska Bridge, which provides a convenient shortcut across Tionesta Creek. We knew we would have to take the long way around, but stopped for a look anyway. Unfortunately the bridge floods several times a year (sometimes becoming completely submerged), because it is located in the upstream end of the reservoir behind the Army Corps of Engineers’ Tionesta Creek Dam. We had over an inch of rain last week, so the bridge is partially under water. On the brighter side, 100 miles downstream, the City of Pittsburgh did not flood.
On Saturday, February 18, 2023, I had a rare opportunity: a full day to play radio.
Instead of doing a five park POTA rove, I chose instead to do a summit activation followed by a park activation.
I published the summit activation on Moore’s Knob (W4C/EP-001) a couple weeks ago and planned to immediately follow that up with this report from my POTA activation at Pilot Mountain State Park (which I activated the same day).
In the process of moving my videos from the camera, to my laptop, and then to PC where I do my remote uploads (my bandwidth at the QTH is far too poor to upload large videos) I somehow managed to delete this particular video file.
I was quite frustrated, actually, because this particular POTA activation was challenging. Lately, I’ve had so few examples of just how quiet a band can be when propagation is less stable.
The SOTA activation I performed only a few hours earlier had some of the deepest pileups I’ve ever experienced. By the time I started my POTA activation a couple hours later, all of this had changed–at least on the bands above 20 meters and I’d chosen 17 meters (a WARC band) since a contest was in progress on 20 and 40 meters.
I’m incredibly pleased that I stumbled upon the raw video files on my backup drive. I was able to reproduce the video in its entirety. I’m so pleased it wasn’t lost!
This is why it’s a little out of sync date-wise with my other reports.
I hope you enjoy this field report:
Pilot Mountain State Park (K-2750)
After capping off a beautiful 4+ mile hike and SOTA/POTA activation at Hanging Rock State Park, I put my SOTA pack in the car and drove 30 minutes to Pilot Mountain State Park.
It being a gorgeous Saturday afternoon, the park was so full of guests the parking lot was completely full. A park ranger had incoming cars form a line and he allowed cars in as guests departed one by one. When I arrived, there were five cars in front of me. I was very tempted to do a three-point turn and head back down the mountain to the visitor’s center to do the activation. There was plenty of parking there.

My CW Journey
by Terry (N7TB)
For many U.S. hams who were licensed before 2007, we had to learn CW at 5 wpm as a Novice or Tech, 13 wpm for a General license and 20 wpm for Extra. Many learned CW at a young age and have used CW since then. It and ham radio are synonymous for them. For many of them, that is the only mode they have used for years.
For me, my experience is quite different.
In 1982 I decided to get my ham license. I bought a Kenwood TS-520S, DG-5 digital display, a 45 ft tower, and a large Cushcraft ATB-34 beam even before I had my novice license: all for $350, a bargain even then (my wife wasn’t convinced). I still had the beam and tower until 7 years ago. In 1982 I had all the gear to work DX using SSB and it seemed to me to be the way to do it. So as a result, I stayed with SSB for decades. Right after I got my license, several ham friends urged me to continue using CW and even invited me to join their weekly CW group to gain confidence and skill. I had absolutely no interest. Several kept at me for years!
I don’t know what causes the “spark” that happens for a person to not only want to learn, or relearn CW as I did, but to also do everything necessary to become proficient. That happened to me when I was 69 years old.
I had tired of SSB and was getting bored with ham radio. I was looking for a new challenge. I decided to see if I could relearn the CW that I had largely forgotten 35 years before. The same friends who urged me to join their group so long ago, welcomed me. Over the first few years I joined them, my confidence and speed increased. Unlike the first time I learned CW, they urged me to not write down anything but to listen to the sound and translate the letters in my head. It was slower than writing it down at first, but it paid dividends later. They all were patient and slowed down for me and increased speed as my skills improved. I still join them every week. They are some of my best friends. We are spread out in WA and OR. On Wednesday mornings we have a QRPP net where we operate 1 watt CW and most of the time we can all hear each other. We never go over 5 watts.
Because I learned CW late in life, I have an appreciation and joy of CW that is hard to describe. It is the greatest joy in ham radio I have ever experienced.
This week, I activated Willamette Mission State Park in Oregon with a wire in a tree and 5 watts from my KX2. I worked 44 contacts, most East of the Mississippi. There are few things that give me as much joy as copying and sending CW. It represents 99.9 percent of all my ham contacts for the last 6 years.
When that day came almost 3 years ago, when I had finished a CW ragchew and was thinking about what was discussed and realized that I never said anything verbally, that my brain had effortlessly translated dit and dah sounds into language and could not tell the difference between speech and CW, I knew I had finally reached my goal of communicating in CW as effortlessly as talking. I will never forget that moment! I was 72 years old. Three years of almost daily work for at least an hour on CW finally got me there. I think it takes longer the older one is when they start.
I guess I could say that CW has become my passion. I don’t know if I would have felt the same way if I had learned it as young man as many hams did in the day. Because I hated CW for so many years and had such frustrations with it, to find myself loving the mode now is an amazing thing.
In a few weeks, I will get the DXCC wallpaper for over 100 CW DX contacts. That, in itself, is almost surreal to me given my history of avoiding CW for so many years. I actually wasn’t working toward it, it just happened because of the ease of confirming contacts through LOTW. My logging software does it for me automatically. Nonetheless, I will take great pride in it because of how much effort it took to become proficient in CW. If someone had told me in 1985 that I would one day achieve DXCC in CW mode, I would have said they were crazy!
I am mentoring several people now as they learn CW. It is exciting to see them progress. It is fun to share in their successes and encourage them as they deal with some of the same things I dealt with.
The thing that has always amazed me and something that I have tried to communicate to those I am working with is that there comes a magical moment when the difficulty of learning CW melts away and all of a sudden you can copy 25-30+ wpm with little to no more effort. Many of you can relate to what I am saying. It’s like a switch is flipped and you will never not be able to effortlessly communicate in CW again.
I will always be grateful to those who helped me on those many weekly hour-long CW chats. That was the key that opened a world that I never knew existed and one in which I will treasure for the rest of my life.
I share this story with you because I know there are others who read Thomas’s blog, striving to become proficient in CW and wonder if they will ever “get it.” You will if you keep at it, and when that magic moment arrives for you when CW becomes effortless, you will have the satisfaction of doing something that so few hams are willing to do. It is worth all the work you put into it! I wish you the greatest success in achieving CW proficiency!
I do my best to shake up each field activation I perform. Even if in some small way.
While it would be way more efficient to deploy the same radio and antenna combination at each park and summit I visit, I get a thrill out of trying different radio and antenna combinations.
I should add that I’m fully aware how fortunate I am to have a lot of radios and even more antennas to pair in various combinations. I keep reminding myself that building and buying radios and antennas is still cheaper than restoring a 1940s era Willys CJ-2A.
Recently, a reader reached out and asked my opinion about the Chameleon Tactical Delta Loop (CHA TDL) antenna. I think the TDL is a brilliant antenna system, actually, and the one I recommend the most from Chameleon because of its versatility.
Not only can it be deployed as a multi-band vertical delta loop but it has all of the parts needed to be an MPAS Lite vertical as well, save the counterpoise.
The CHA TDL comes with a 25 foot wire that connects the two 17′ whips into a loop configuration, but the clamps on the end of that wire can’t connect to the ground lug on the MPAS ground spike terminal as-is. That said, you could easily make a short connector cable or connection point that would allow the CHA TDL wire to clamp to the ground spike terminal. Else, of course, you could cut a dedicated 25′ counterpoise from pretty much any wire you might have around the shack.
You can buy the same counterpoise used with the MPAS Lite package, but it’s more affordable just to build your own since there’s no magic in the counterpoise. And, FYI, configured as the delta loop, there’s no need for a separate counterpoise; only if you configure it as a vertical.
This same reader also has an Icom IC-705 and an mAT-705 Plus antenna tuner. He was curious how well that combo might work with the CHA TDL. I knew that the combo would work well, but I thought, “why not try it?”
I realized that it has been ages since I last deployed the CHA TDL in the field.

Tuesday, February 28, 2023, was a gorgeous day weather-wise, although it was a bit gusty at times.
I arrived at K-6856 and decided to film the full set-up of the CHA-TDL.
For an antenna with a fairly large profile when deployed, it’s actually very compact, albeit a bit heavy (mainly due to the weight of the solid stainless ground spike and TDL hub). That said, I did take this same CHA TDL setup on an 11 mile round-trip SOTA hike once and didn’t find it too heavy.
I love going truly portable with my radio gear; packing an entire minimalist station in my backpack along with first aid supplies, water, and a bite to eat, then hitting the trail.
I love the views.
I love the sense of accomplishment (hiking to a summit doesn’t happen every day).
I also love that post-hike feeling–my body telling me, “Hey, T, thanks for doing something today!“
No kidding: If I could, I would do a SOTA activation at least twice a week. Maybe when I retire, I will.
It’s because they are much more difficult to fit in my active schedule.
You’ll notice that the bulk of my POTA activations take place within a one hour window of time. This includes set-up, on-the-air, and pack-up time. The brilliant thing about POTA sites is that they’re so accessible in my weekly travels. (Plus, I absolutely love POTA too!)
My average SOTA activation, on the other hand, requires at least a three hour window of time. In fact, it’s usually much closer to four or five hours.
The view from Dogback
Drive-up summits like Anderson Mountain and Dogback Mountain are the exceptions. There’s no hiking time involved, so they are pretty easy to fit into my schedule.
On Saturday, February 18, 2023, a rare thing happened: an entire day opened up for me to play radio. The only real obligation I had was to set-up and participate in a live stream with Josh (KI6NAZ) on the HRCC channel that evening.
At first, I thought about doing a five park POTA rove, hitting four parks and one game land all that eight hour window of time. It was very doable and I knew it would be fun.
But then again, park roves allow very little time for hiking–typically, they’re wham-bam style short activations. It was also a gorgeous day weather-wise so I scrapped the idea of a POTA rove. (This time!)
It’s been nearly two years since I’d visited Hanging Rock SP because it’s a two hour drive in a direction I rarely travel.
Hanging Rock a beautiful park and I truly enjoyed the hike to Moore’s Knob.
As a bonus, Hanging Rock State Park is less than a 30 minute drive to Pilot Mountain State Park. I knew I’d have time in the schedule to do activate both sites! Score!
Hanging Rock State Park (K-2753)
I pulled into Hanging Rock that morning and made my way to the parking area by the lake.
On Sunday, February 19, 2023, I felt like I was moving in slow motion.
The previous day started early and I fit in a long hike, a SOTA/POTA activation, and a second park activation. Round trip driving time was about four hours, but it was worth it. I had an amazing time. Those field reports will be posted in the upcoming week.
The previous evening, I also participated in a live stream and after hours chat with Josh (KI6NAZ) on his amazing Ham Radio Crash Course channel. It was loads of fun, but I was up pretty late after a long day.
Sunday morning, I was feeling it and couldn’t decide if I wanted to do a POTA activation on the drive back to the QTH. In case I decided to, early that morning, I scheduled an activation at Table Rock Fish Hatchery with a very wide activation window. I often don’t have enough mobile phone service to self-spot at that particular site, so I decided that if I was able to make the activation, it would cover me.
I wasn’t even ten minutes into the drive home when I decided to go for the Table Rock activation, of course! I seem to never be too tired for some POTA!
I did make up my mind in advance to try to activate the park on 17 meters because 1.) there was a CW contest that weekend, and 2.) I wanted a more laid-back activation instead of a pileup. I figured 17 meters would have some activity, but not to the degree of the non-WARC bands.
Table Rock State Fish Hatchery (K-8012)
I decided to record the entire activation from set-up to pack-up so I grabbed the action camera from my radio bag in the passenger’s seat and started recording as I pulled into the site.
I had a lot of gear in the trunk/boot of my car–more than normal–because I brought along quite a few radio packs to show on the HRCC live stream for this trip.
I grabbed the Penntek TR-45L and PackTenna random wire. I thought they would pair nicely for a casual POTA activation.
My Postcard Field Reports are information-packed, just slightly more concise and distilled than my average field report so that I can publish them on a busy day.
T-T R4020
One of the least expensive radios I’ve ever purchased is my TEN-TEC R42020 two-band CW only radio. I believe I paid $120 for it (shipped!) a couple years ago and it sat on my shelf unnoticed for months until I took it on a POTA activation last year.
Here’s the admission: I really love this little radio!
It is not a feature-rich radio, and the sidetone sounds like a 1080s handheld arcade game, but it works a charm! The receiver and audio are fantastic and it sports two of my most useful POTA/SOTA bands: 40 and 20 meters.
What’s not to love?
POTA time!
I had an early morning doctor’s appointment on Thursday, February 23, 2023. As a little reward for doing my annual physical I decided to add a POTA activation to my morning. This was a last minute decision, so only a couple minutes before leaving the house that morning, I grabbed my TEN-TEC R4020, the Chelegance MC-750, and my Spec Ops Backpack (filled with all other field accessories), and I hit the road!
I chose the MC-750 that day because I needed an antenna that could be configured to be resonant on 40 meters since the R4020 has no internal ATU. That and I couldn’t remember if I’ve configured the MC-750 for 40 meters in the past. I know I’ve deployed the MC-750 with the 40M coil, but I think I may have used an ATU to match it.
As I mentioned in my recent AX1 vs AX2 video and blog post, I purchased an Elecraft AX2 antenna and bi-pod in late January (note: two days before Elecraft announced their February ’23 sale price! Doh!).
I received the AX2 package a few days later and I was certainly eager to take it to the field.
My first opportunity came on Tuesday, February 14, 2023, when a short activation window opened up in the afternoon.
Zebulon B. Vance Birthplace (K-6856)
One of the first things I noticed after taking the AX2 out of the package is just how solid and compact it is. The AX1 is short, but the AX2 is a few inches shorter because the base is more compact.
Unlike the AX1, the AX2 is a mono band antenna, thus the coil only needs to accommodate one band. When you receive a new AX2, it’s configured for 20 meters out of the box, but the user can modify the coil to work anything from 20 to 6 meters.
“Resonant-ish”
Even though I mentioned this in my AX1 v AX2 article and video, I’d like to reiterate that the AX2 is nearly-resonant on 20 meters. It is not reliably resonant.
I’ve still been receiving a lot of messages from readers stating that their AX2 and AX1 are resonant on 20 meters, so they don’t pack any sort of matching device in their field kit. They simply hook the AX2 up to their little QRP radio and hop on the air.
While it’s true that these antennas may provide an acceptable SWR most of the time, you really can’t rely on a solid, reliable match as you could with an end-fed half-wave.
I’ll repeat what I mention in a previous post:
Small verticals like the AX1 and AX2, that use coils to electrically “lengthen” the antenna, have a higher Q than, say, a large aperture quarter or half wave antenna. In practical terms, this means that the window of resonance is narrow and more fickle than, for example, an end-fed half-wave.
A lot of factors can affect the SWR on higher-Q antennas like the AX1/AX2 including:
the type of terrain,
height off the ground,
length of counterpoise,
configuration of counterpoise,
and, most notably, the operator’s own body capacitance.
You may find that the AX2, for example, is natively resonant on 20 meters at one location, but isn’t at another location. This is quite normal. It’s also the reason why Elecraft states that both antennas are designed to be used with an ATU.
So there you go! If I hook up my AX1 or AX2 to a radio, I’ll always have some means of matching the impedance–either an external ATU, or a capacity hat. You can also tinker with the length of the telescoping whip and counterpoise to tweak the match.
On Friday, February 10, 2023, I had a hankering to fit in a POTA activation that morning. South Mountains State Park was an easy detour on my drive back to the QTH, so I scheduled an activation.
Brooks has been steadily working on his CW skills and is dangerously close to doing his first CW activation. We’ve managed to set up one late evening casual CW rag chew and I think his CW chops are very good. We plan to do more evening rag chews when our schedules align. He’s made amazing progress.
I contacted Brooks that Friday morning and he was game to meet up and do some POTA. He wasn’t quite ready to do a CW activation, so I suggested he log for me using the HAMRS app on my iPhone. I find that logging for CW ops during past Field Days really helped build my own confidence before I started using CW daily.
Brooks was 100% game to log for me.
And let me just say what a luxury it is to have someone log to HAMRS for me on my iPhone! It frees up my brain to simply log on paper (which I always do) and enjoy working stations without the extra busy work! Hat tip to good ole’ Brooks.
South Mountains State Park (K-2753)
I arrived at South Mountains State Park (the Clear Creek Access), put on my hiking boots, then Brooks pulled into the parking lot only a few minutes later.
We agreed in advance to fit in a quick hike up the Clear Creek Trail prior to the activation. I, for one, really needed to stretch my legs!
After the hike, I grabbed some gear from the car and we set up at the one picnic table at the Clear Creek Access.
Brooks and I both had commitments that day so could only play radio for 45-60 minutes max including set-up and take-down.
I deployed the same antenna I’d used the previous day: MW0SAW’s homebrew EFHW on a SOTAbeams winder.
