“Return-to-Office Policy” triggered POTA activation

“Return-to-Office Policy” triggered POTA activation

by Thomas (DM1TBE)

I wasn’t sure if I should write a report about this activation. It was “average” at best. But I thought it might be worth to share that not all activations are perfect, with stunning views in an enjoyable environment.

Intro

I am a relatively new ham and completed my first exam in mid-2019. It took me a while to get my head around all the things that the new hobby is offering. My first successful portable activation was in May 2021 on the SOTA summit Michelsberg (DM/BW-855) – here is a picture of my most recent activation some weeks ago:

This first activation was in the middle of the Corona pandemic. The good thing during the Corona time was certainly the possibility to work from home. Before Corona, I did commute roughly 65 km / 40 mi (oneway), which took me in total 2–3 hours daily. During the first two years, I was in the office two times. In the third year, I was there more often, maybe once every two months.

Two weeks ago, my employer announced a “return-to-office” policy, so the “sweet life” was coming to an end.

After the first disappointment, I thought that this may offer me the chance to work portable at new locations. The next SOTA summit is around 20 km / 12 mi away, but a POTA park begins 2 km / 1.2 mi from the office at the pin in the map below. The park is basically all the green wood in the center of the map.

That comes in very handy, as POTA, with the possibility to operate next to my car, does make it easier than hiking in suit and tie to a SOTA summit.

The Nature Park Schönbuch, POTA DA-0008, located southwest of Stuttgart, is a wooded area of 156 km² / 38,000 acres. In 1972 in became the first nature park of the federal State of Baden-Wuerttemberg. The park is an important recreational area for the region.

Activation

Right at the beginning of the park, when coming from my office, there is a parking place and next to it a clearing with a fireplace. I thought that this would be a perfect spot for my activities. Weather was cold and windy on my first “return to office” day, I did not expect too many people to be there.

After working and reading the article about the 2023 QSO Today Virtual Ham Expo, I decided to leave the office early at around 4pm and started my activation.

The parking place at the park was pretty empty, just one old car with four lads in it and doing whatever lads are doing in the woods. I have a 16-year-old son and have given up trying to understand what boys at that age are doing.

The spot was OK, but not as perfect as I had thought. It was in a trough surrounded by large trees. In addition, it was wet, cold and windy.

Due to the wind, I have decided against the 10 meter / 33 ft pole and used the PAC-12 again.

The actual activation did not go as smoothly as my previous one. It might have been due to the time, and afternoon during the week, or the topographical conditions. With a small foldable seat and a tiny desk made of a trunk and a brick, I operated for 40 minutes.

In total, I made 16 QSOs; 10 on the 30-meter band and 6 QSOs on 20 meters.

Although I made a successful activation of the Nature Park Schoenbuch, DA-0008, I think I need to change my plans. Being in the office and therefore close to this park more often in the future, I will be more picky in terms of weather and location. The park has way more to offer than a wet and cold meadow in the middle of the woods. I will look for better weather and locations, such as the following – I just need to find those places.

Postcard Field Report: Cheap POTA thrills with the TEN-TEC R4020 and Chelegance MC-750

5 Comments

Welcome to another Postcard Field Report!

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.

I arrived at the Blue Ridge Parkway (K-3378 NC) mid-morning and set up in very short order. Continue reading Postcard Field Report: Cheap POTA thrills with the TEN-TEC R4020 and Chelegance MC-750 →

CQ From Latvia with Love

A completely under-prepped SOTA & WWFF activation which turned out to be perfect

In preparation for a tough conversation a good friend once told me: “You know what, just walk into the fire. If you have bad news to deliver, don’t sugar coat it and do it right away. You’ll be fine.” 

“Just walk into the fire.” I believe this can be applied to many other situations in life. While I would consider myself to be well-prepared on most trips, hikes and activations and getting a lot of joy out of optimizing my kits I try to stay open-minded. Imagine the things you would miss out on if you wouldn’t be spontaneous or only do things while fully prepared and 100% safe – even if it means taking risks.

On the road back to Riga
The QCX-Mini silently drying after a successful activation

Last Wednesday, I kind of walked into the fire. Not fire as in fire-fire but fire as in Latvian winter storm. In general this wouldn’t be such a big deal had I brought the right clothes, gear and shoes to my short business trip to Riga.

Due to very strict luggage restrictions I could only bring one small backpack for three days. Inside I had enough room for a laptop, washbag, spare clothes and the compact QCX-Mini Kit I built for exactly these occasions. I was wearing sneakers and jeans. At this point I had not planned a specific activation but I wanted at least to be able to operate YL/ & /p maybe 30 minutes from a nearby park – not a problem if you can jump right back into the warm hotel afterwards.

My rental car rocking summer tires in Winter (yes, I was driving veeeeeeery slowly)

During our stay, my schedule for Wednesday morning freed up so I decided to try activating one out of only three SOTA summits in Latvia: YL/YL-003. It turns out this summit is also located within WWFF territory YLFF-0007 about a 1,5h drive from Riga. Big Thanks to Val (YL2SW), Latvia’s WWFF manager, for assisting me with local rules and processing my log. A quick look at the weather forecast showed freezing temperatures, 90% chance of snow, heavy winds and overcast. Many of you will understand why a SOTA&WWFF combo in a rare country could be a small reason not to use the hotel’s sauna on a day like that. Sometimes things just need to get done.

I got up early the next morning and was very happy to be able to grab a Bolt rental car from the street and get going quickly. The drive went by without issues up to a point just about 3km away from the mountain (well, 1-pointer hill I should say). The roads were completely covered in snow so I could barely see where I was driving. Latvia is a rather flat country but here it started to get a bit hilly and the tires were certainly not cut out for that. Continue reading CQ From Latvia with Love →

Breaking in the new Elecraft AX2 during a short POTA activation

6 Comments

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.

The important part–especially if pairing these antennas with a radio that lacks both an internal ATU and SWR meter (say, the MTR-3B, G106, or TR-35)–is that you’ve some means to check the SWR before conducting a long activation session.

How I found the best antenna for my SOTA/POTA activations

How I found the best antenna for my SOTA/POTA activations

by Thomas (DM1TBE)

Intro

Until January this year I had a German “Klasse E” / CEPT-novice amateur radio license (equivalent to the US General Class), which limits the use of HF to the 10-,15-, 80- and 160-meter bands. When I started with SOTA I used homemade single band end-fed antennas most of the time. However, that is only feasible for the 10- and 15-meter bands.

Unfortunately, both bands are very moody and sometimes they have not worked at all. Unlike the UK for example, FM is uncommon for SOTA in my home association DM (i.e. Germany Low Mountains). You can be lucky and get your 4 QSOs, but I did not want to rely on pure luck.

Therefore, I bought an end-fed half-wave antenna for 10-, 15-, 20-, 40- and 80-meter bands, after some experiments with 10-80-meter end-fed half-wave antennas, from a small German company called ANjo.

Although I could not use the 20- and 40- meter bands at that time, the EFW80-10P (en: auto-translated) antenna gave me the possibility to use the 80-meter band. The antenna could also be tuned for 15. It has a mechanical length of 23.6 m / 77 ft and a coil for the 80-meter band. It is pretty lightweight with 0.4 kg / 14 oz and allows up to 30 watts PEP – more than enough for me. 80-meters is not the best band for daytime SOTA activations, but in 21 months doing SOTA activations, it worked 37 times and tipped the scales for an activation from time to time.

It was sometimes a bit tricky to raise the long wire into the air, but it always worked … better or worse …somehow … like here in the woods along a trail.

In January this year, I upgraded my license and a new world of HF-bands opened for me. Although I have learned a lot about propagation for the exam, I am in favour of a German saying: “The difference between theory and praxis is larger in the praxis than in the theory”.

Field Report: More Xiegu G106 POTA time and I rope in Brooks to log!

5 Comments

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.

I’d also been meaning to meet up with Brooks (KO4QCC). Brooks started his POTA journey not even one year ago–here’s a field report from his first SSB POTA 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.

Deployment didn’t take long–since the 40M EFHW is resonant on both 20 and 40 meters, there was no need for an external ATU. I powered the G106 with a 3Ah LiFePo4 battery via my Ham Radio Workbench DC Distribution Panel. Continue reading Field Report: More Xiegu G106 POTA time and I rope in Brooks to log! →

Giving the Xiegu G106 a thorough workout at Fort Dobbs!

7 Comments

On Thursday, February 9, 2023, a rare opportunity opened up for me: a 3.5 hour activation window–!

I was visiting and helping my parents in Catawba County, NC, so considered the park options, almost all of which are within a 35-45 minute drive.

I thought about fitting in two shorter park activations that day, but it has been so long since I’ve had the opportunity to simply hang at one park and play radio for more than an hour, I chose the extended activation option.

Although the forecast was for clear skies that day, a front was moving through that afternoon and the skies were overcast with gusty winds. I could tell rain was a very real possibility, so I chose a site with a picnic shelter to make things a bit easier.

Fort Dobbs State Historic Site (K-6839)

Fort Dobbs was a no-brainer: not only was it the closest park (thus less travel time eating into my on-air time), but the staff there are very POTA-friendly, the site is quiet, and they have an excellent shelter that I suspected (due to the dodgy weather) would be unoccupied.

When I arrived on-site, I checked in at the visitor’s center to make sure the picnic shelter hadn’t been reserved. Fortunately, they said I could have the shelter all to myself!

I had a number of radios in my car and decided en route that I would use the Xiegu G106 once again.

I packed the G106 in a waterproof Husky radio gear box I keep in my car trunk/boot. I grabbed it and my Spec-Ops EDC pack and carried it to the picnic shelter.

My plan was to pair the G106 with MW0SAW’s 40 meter EFHW antenna.

This would give me two resonant bands (40 and 20 meters) so there’d be no need to connect an external ATU. Continue reading Giving the Xiegu G106 a thorough workout at Fort Dobbs! →

My conciliation with Parks on the Air

by Thomas (DM1TBE)

Intro

POTA and I had a very one-side relationship so far.

Roughly a year ago I tried to activate a park, but although I spotted myself, I had not been able to make a single QSO. In April last year, I tried it again, with the same result. Luckily, I was on a SOTA summit and spotting me on SOTA brought me enough QSOs to make it a successful activation for both, POTA and SOTA. So I decided to disregard POTA and my only POTA activity was watching Thomas (K4SWL) nice videos on YouTube.

My bad experience with POTA was probably due to two factors:

  1. I only had an intermediate license previously, which limited me on HF to the 10, 15 and 80 meter bands and
  2. POTA was no as popular in Europe and Germany in particular as it was and is in the US. While SOTA and the Flora & Fauna program already had a very active community in Europe for years, POTA had a hen and egg problem.

However, with the increasing popularity of portable operations, POTA has also gained some traction in Europe. I have the feeling that every time I take a look at the spots on the POTA website, I see more European stations.

Things here in Germany have changed for the better, too. POTA got a German website (parksontheair.de) and a community called “Draussenfunker.de” (“Outdoor ham”) with website + Discord that became very active with those pursuing outdoor activities in general and POTA in particular. Lately, local POTA coordinators have been named, who started to add new parks to the program.

I thought suggesting a recreation area close to my home would be a good idea. A few days later I had the brand new POTA park DA-0410 30 minutes away. The park has a size of 6.3 km² / 1,567 acres and a peak elevation of 780 m / 2559 ft, which is also the SOTA summit Kaltes Feld (DM/BW-659).

My plan was to operate from the clearing on the top plateau, where there is also a mountain hut with restaurant. The 2 km / 1.25 mi trail was not very difficult with an incline of just 105 m / 344ft as the parking area is already at an elevated level.

Although the park extends to the proximity of the parking area at the Hornberg gliding airfield, I wanted to be in the SOTA activation zone due to my bad experiences with POTA activations. The gliding site was founded nearly 100 years ago.  After the First World War, the Allies largely banned motor flight sports in Germany, so gliding airfields, such as this one, popped up across Germany.

Lunch Box POTA: Pairing the Elecraft AX1 with the Penntek TR-45L!

14 Comments

As I mentioned in previous posts, I’ve been using the Elecraft AX1 in heavy rotation this year. I made a commitment to myself to do a string of activations with it in January and February and also pair it with a wide variety of radios beyond the Elecraft KX2 and KX3.  So far, I’ve paired the AX1 with the:

In truth, the AX1 can be paired with any radio when you use a tripod mount.

It’s a bit trickier when connecting the AX1 directly to a radio and using the Bipod as a support because 1.) the antenna connector on the radio mustn’t be too high off of the surface, 2.) there needs to be enough clearance on the back of the radio to accommodate the bipod legs and 3.) ideally, it’s nice to have a ground point on the radio, else you’ll need to clamp the counterpoise to the shield of the BNC connector.

In addition, if your radio doesn’t have a built-in ATU of some sort, then you’ll also need a capacity hat or external ATU to finish off the impedance match. (For more notes about the AX1 and AX2, check out this previous post.)

Of course, you don’t have to use Elecraft’s bipod to support the AX1 when directly connected to a radio–you can build or 3D print your own support–but the bipod is really convenient when it does work.

Objective: Lunch Box Radio

One radio I’ve been eager to pair with the AX1 is the Penntek TR-45L.

Why? Because I love the form-factor.

Something about having a lunch box-sized radio sitting on a table with a telescoping whip protruding out the back and, with that combo, the potential of making contacts all over the globe. Continue reading Lunch Box POTA: Pairing the Elecraft AX1 with the Penntek TR-45L! →
