Over the past few years, I’ve received numerous requests to check out the Yaesu FT-891 HF transceiver. Almost all of my ham friends have one and they are widely considered one of the best 100 watt HF radios for park activators. Indeed, I bet it is *the* most popular 100W radio among POTA activators.
I’ve been tempted to ask Yaesu for a loaner model and I even came within one button click of ordering a new FT-891 from DX Engineering during a Black Friday sale in 2020.
I’ve resisted the FT-891 temptation, though, because I tend to use smaller, more portable QRP radios in heavier POTA rotation. I knew if I purchased an FT-891, it just wouldn’t get a lot of field use. It also demands a beefier field battery due to its current requirements and, frankly, it’s so rare I run more than 5 watts (and 5 watts is the lowest power setting on the ‘891) I would simply have a lot of radio for my needs.
A few weeks ago, however, a friend reached out because he wanted to sell his FT-891 and 30Ah Bioenno battery and downsize to a smaller field portable radio like the Xiegu X5105. Long story short, we worked out a trade/purchase which included the ‘891 and his battery. I had been thinking about a large capacity battery to use as a backup in the shack, so this worked out well for both parties.
Zebulon B. Vance Birthplace (K-6856)
On Tuesday, March 14, 2023, I once again had an hour to fit in an activation at the Vance Birthplace before picking up my daughters at school. I’ve really enjoyed the opportunity to play radio at Vance so much during this particular school term; next term, it’s unlikely I’ll have this opening, so I’ll enjoy it while I can!
I deployed the Chelegance MC-750 vertical again. I’ll admit that it’s so convenient keeping an antenna in the car trunk/boot that can be made resonant so easily from 40 meters and higher.
I was going to show the antenna deployment again in my activation video, but received a call and decided to deploy the antenna while finishing up the phone call. It only takes a couple of minutes to set up.
Next, I connected my 15Ah Bioenno battery to the FT-891. Even though I was only using five watts, the ‘891 needs more capacity than the 3Ah packs I normally carry with my QRP rigs.
Nearly a week has passed since my last activation and the AWS–the Activation Withdrawal Symptoms–started to kick in. Furthermore, I received an antenna during the week which I wanted to try. However, the weather was unsettled, and showers were forecasted over the whole weekend. This did not prevent me to try at least an activation with the new antenna.
So, I started to the Wasserberg (DM/BW-664) on an early Saturday morning. The summit has a height of 750 m / 2460 ft and a wooded peak. The parking place is already elevated, so there was only 1.6 km / 1 mi left to walk with an ascent of 166 m / 540 ft.
The peak is wooded, but you can enjoy the view at the beginning of your hike, just after parking.
The trail is well-developed and easy to walk, except for the high incline at the beginning.
You come along something that looks like an old wall, but it is probably a place where stones have been taken from in earlier times.
The forest still looks like winter, and you can see the landscape through the trees
But if you look close enough, you see that the spring is not too far anymore.
Although the way to the peak diverts from the well-developed trail half way, I followed the way to visit the Wasserberghaus (it basically means “house on the water hill”, with “water hill” being the name of the hill).

Fishing Hole Reflections
by Lee (K2LT)
Last week, I completed my 80th activation of a state forest very close to my home – Deer River State Forest (K-5199). That earned me what in POTA is called the “Fishing Hole” activator award. Compared with the achievements of other activators within POTA, it’s not at all a big deal. Yet as I sat on my camp stool in the snow in the middle of the woods last week with my radio, I realized how big of a deal it has been for me. There was no wind, I was surrounded by huge Red Pine trees, and the only noises were an occasional airplane, woodpeckers, ravens, and my CW signals. I was happy!
All of my activations of that spot haven’t been QRP but as I look back at my favorite memories from ham radio (I’ve been licensed for about seven years), they’ve been when I’ve put my gear into a backpack, found a secluded spot in the woods, sat on my campstool and operated from there.
This time of year is also my favorite. Our winters in Northern New York State (I’m only about 20 miles south of the Quebec border) are LONG. In late March when winter starts to lose its iron grip on our region, we’re all “chomping at the bit” for spring to arrive. Yet, as things get warmer in late April and May, the Adirondack black flies, mosquitoes, and deer flies will come out in force. In the fall, deer hunters populate the state forests and can make activations dangerous, and deep winter doesn’t often work unless I operate from my truck – numb fingers and CW operation don’t do well together. So, early spring is often the perfect time to be able to operate outdoors.
A couple of times, I’ve had POTA hunters inquire why I don’t post my activations prior to heading out. My wife and I have an adult disabled son in his twenties. We’ve made the commitment to keep him home with us as long as we can. As with all things in life, this decision comes with a cost. It means that I often only know at the last minute whether I’m going to be able to get out for a few hours. Having K-5199 so close has been a real blessing – I can get there and back quickly and do something that brings me a lot of enjoyment at the same time.
Learning CW in my fifties was a challenge, but the first time I saw a video of someone working an MTR-3B from a summit, I knew I had to try it. If I’m working a CW pile-up, I can’t be thinking about anything else. Deciphering signals and logging them correctly takes all the mental “bandwidth” that I’m able to muster; however, in an odd way, it’s also very refreshing – I get a vacation from the things that I’m usually preoccupied with. I always come back mentally refreshed. I’m sure my wife and family appreciate the break I’ve had as well!
Even though I’m retired, I’ve been taking some online classes. One question that often comes up in the “Introduce Yourself” section is – “tell us something unique about yourself.” Years ago, I always struggled with this request, but not anymore. I sometimes respond by saying, “For me, being out in the woods with my radio making contacts is like an afternoon at the beach for someone else.”
Ham radio and portable operating have truly been a blessing for me and I’m thankful for them.

POTA – Getting There
by Dennis (WQ7O)
POTA activity seems to be popular and growing. I have been a ham since the 60s and I am excited by how fun POTA hunting and activating this “new” radio sport can be. I have heard it called “Field Day” every day.
Drawing on decades of hamming experience, I contemplated how we got here. I remember my first field day and the effort required. Basically, equipment meant to be used in an indoor and fixed environment was adapted for portable use. Let’s take a look at what that might mean.
Power supplies that operated on DC were available but expensive. Looking at say, a Drake
TR-4, a popular transceiver at the time, the rig cost $700 in 1968 dollars. The power supply and speaker ran another $200 or so. You’ll need a mic and key, which were not included. Few tuners were available. You could go for a Johnson Matchbox. Drake made the MN-4 and
MN-2000 to match your TR-4. Count on another $200 or so. If you are a CW op and you want a keyer, the Hallicrafters TO keyer and a Vibroplex paddle were another $200. The gear described here would just fit on an office sized desk and don’t ask about the weight.
Now just gather that up and take it to the park, right? Well for starters the DC supply was for mobile use not portable use. You won’t operate for long off a battery with the amperage needed to warm all those tubes. So, bring along a generator and that’s what we did. BTW, we used a truck to transport it all because we needed it. Backpacks weren’t useful.
Antennas were all for fixed use as well. We brought a tri-band yagi and lashed it on a mast to the truck. We ran some wire antennas and we were on the air. Antenna analyzers simply did not exist, we tuned around and graphed it by hand.

This may sound much like a modern field day but hardly the “light and fast” deployment of a SOTA/POTA activation. Also, take it from me, running tube gear in the field is tough. I had a Gonset Communicator (2 meters) issued to me by our ARES group. It was about 100 times the displacement of your trusty handheld and many times the weight.
So since the 60s, the microprocessor, large scale integration and SDR technology have reduced the size and power requirements for all the gear we use. Today a radio that fits in a pocket can include a rechargeable power source, an antenna tuner and run from 160 meters through UHF offering all modes.
From lead acid, NiCads, NiMH, Lithium Ion and now LiPO batteries, the availability of reliable and portable power sources to power rigs and accessories is a fairly recent development. The increased efficiency coupled with decreased power demand have set us free. How many of us have quick deployment solar panels to keep those batteries topped off during extended operation? It beats the noise, smell and mess of gas cans and a generator. Also, you do not want to backpack a lead acid battery for a SOTA activation. Too much weight and not enough power.
Then there is the internet. If you do POTA like I do POTA, you go to the web page and look for spots. How many would you find without the spots and the RBN? When an activation is deployed one of the first actions is to spot it on the POTA app. Thus, as with other digital modes, the internet becomes an integral part. We could do POTA without the internet, but it would be a whole lot harder. And our taken for granted cell phone brings the internet right to the picnic table.

What about the gear? What should we use and how available is it? Early rigs for portable and QRP use were not plentiful or feature rich. The styling of the popular Penntek TR-45 is reminiscent of the Heathkit “Benton Harbor Lunchbox.” At the risk of understatement, the features do not compare.
The manufacturers responded. We weren’t all going to home brew our QRP rigs. So came the Yaesu FT-817. In 2001, Yaesu introduced the 817 which did all modes, 160 through UHF, ran on batteries, fit in your backpack and was affordably priced. Suddenly, portable operation was possible, versatile, affordable, reliable, practical and fun. We were freed from attics, basements and garages and embraced nature.
I recently built a QRPLabs QCX mini. This tiny rig has more features than we ever knew we needed when we were operating that Drake TR-4. If you want more bands the LNR Mountain Toppers are wildly popular. Other manufacturers, large and small, increased the offerings with different form factors and features.
This included antennas. An early entry was the Buddipole. Many cottage industry entrepreneurs followed and today the selection of quick and easy deployment antennas is broad and deep. From a whip antenna to attach to the rig itself to wire antennas for 160, there are a lot from which to choose. Don’t forget that 3D printing also accounts for a lot of our accessories like keys, cages, stands and winders.
Want to add a tuner to your station? The Elecraft T1, I built mine as a kit, is a superb, self contained tuner and offers broad, automatic matching running on a 9 volt battery. Since the T-1, LDG, MAT MFJ, Icom and others have offered great tuner choices that travel easily as part of your kit.
Anyone who owns a Baofeng knows that the Chinese have entered the ham radio market. While the quality and availability of these rigs can be an issue, they are quite affordable. This brings in new users who learn the hobby and progress to greater things. I have heard hams criticize the quality of MFJ products. MFJ makes the accessories the major manufacturers don’t and at popular prices. When there are more licensed operators, the manufacturers can offer more products at better prices as markets expand. Xiegu HF radios have powered many activations with its built-in battery, tuner and microphone. If POTA and QRP were not driving activity would Icom have brought out the IC-705? The Elecraft KX-2 and 3, the Lab 599 TX-500 and these types of boutique radios answer market demands.
The “Prepper” movement evolved from natural disaster “EmComm” and operating “off the grid” has increased the demand and thus the supply of gear. Building a portable kit has gotten easier and more affordable with a broad selection of choices and options. More is better.
Lots of other simple things have come together to bring us to the “10 minute setup” of the QRP SOTA/POTA activation of today. A whole room full of heavy, power hungry gear has been reduced to a device that literally fits in a pocket. Add a wire and you are on the air. My ham career began as a boy with a tube driven Heathkit transmitter with crystal control fixed frequency in the attic of our family home. I don’t think anybody appreciates more than me opening a backpack and in a few minutes setting up a modern station, wherever I am. QSOs around the country and around the world roll in with a few watts and a wire.
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.

From Open Source Project ADX to Kit ADX-S
by Adam (BD6CR)
BD6CR @ CRKits.COM
Original Design: WB2CBA
Modification and Kitting: BD6CR
I knew Barb, WB2CBA from his uSDX design a few years ago and I introduced both DL2MAN and his designs in my blog. So, when I came across the ADX – Arduino Digital Xcvr a few months ago, I immediately ordered both the ADX (through hole) and the ADX UNO (surface mount) PCB samples.
I started building the ADX UNO and put it in a dental floss case and made a few contacts on park bench. However, the soldering is too much for my eyesight. So, I turned back to the ADX because I don’t need to solder any SMD parts, since both the M328P and SI5351 are module based. I could build the project in 3 hours and it worked the first time.
However, I felt unsatisfied with the strong BCI since the CD2003 radio receiver chip was connected as a direct conversion receiver. JE1RAV mentioned in his QP-7C modification project that he tried JA9TTT’s idea to build a superhet SSB receiver with the TA2003 or CD2003, so I tried and it worked very well. I have decided to name the new circuit as ADX-S, where S stands for Superhet.
I shared the great news with Barb and he encouraged me to carry the flag to make it a kit, since my design D4D was his first digital radio and he loved it.
My hardware modification can be outlined in this schematic. I have added an FL1, PFB455JR ceramic filter by Murata and a C25 coupling capacitor from CLK2 of SI5351 module. The RX audio comes from pin 11 instead of pin 4.
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.
Zebulon B. Vance Birthplace (K-6856)
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.
If you have read my previous activation reports, you may remember that the temperature was more often than not below 0° C / 32° F. I am tired of the winter. So I was very pleased when the weather forecast indicated 18° C / 64° F on a Saturday.
In one of my previous posts (How I found the best antenna for my SOTA/POTA activations) I have outlined, that I like using the 30-meter band for being reliable on short and medium distances – in my case, Central Europe. However, I wanted to try an activation with an antenna that is more appropriate for DX. The wire winder for my 30-meter antenna had plenty of space left, so I decided using a commercial 12/17-meter band wire antenna that I have discussed briefly in the report linked at the beginning of this paragraph.
The day before, I built a 20-meter end-fed with parts that I found in my basement and a tiny 1:49 transformer from K6ARK. I added a short coil, so the feed point wouldn’t be at or too close to the ground when using my 10 m / 33 ft fiberglass mast. I know it needs some polish.
The Limburg
The Limburg is a conical summit about a 30-minutes drive from my home. It can be activated for a couple of programs like SOTA (DM/BW-110), POTA (DA-0203), WWFF and COTA.
The Limburg is, or better was, a volcano; technically, a volcanic vent of the Swabian Volcano, a volcanic area of 50 km / 31 mi radius with over 350 volcano vents. Seventeen million years ago, it produced massive gas and dust explosions. Be careful when ramming your antenna groundspike into the ground ;-). So it became a steep summit, elevated around 200 m / 650 ft over its surrounding area.
Earliest traces of population around the summit date to 3000–1800 BC.
Around 50 years later, his son Berthold II. built a new castle some 150 km / 90 mi away and moved the seat of the family. Shortly thereafter, the castle was destroyed (probably, nobody knows exactly). It was rebuilt and destroyed again in 1130 and rebuild again. After the year 1150 a new, larger castle was built not too far away and this castle lost its importance and, eventually, gave up.

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.
After a rainy and windy Friday, the weather was expected to improve a bit the next day. The temperature was still forecasted with around 0 °C / 32 °F, but no rain was expected. So, my friend Jochen (DG1PSI) and I thought we could operate outside. We have chosen a summit called Bernhardus. The summit is next to “Kaltes Feld” on the opposite side of the valley, where I was a some days before. With an 1.2 km / 0.75 mi trail and an ascent of 124 m / 440 ft, it is not the hardest summit around.
We had an appointment for 10 o’clock. The parking lot was still empty at the time, but the weather seemed a bit more difficult than expected. We have asked some other members of our local ham radio club if they want to join us. But surprisingly, no one wanted to get up early on a Saturday morning, hike and operate a radio in freezing temperatures.
As mentioned, the summit was near “Kaltes Feld”, on the opposite side of the valley. You can see the SOTA activation zone of “Kaltes Feld” on the left, the glider airfield in the middle and some miles in the background another SOTA summit called “Stuifen”.
The peak was easy to reach and invites enjoying the beautiful view.
