Treetop Antennas: Featured with my friend Wlodek (US7IGN) on BBC Radio 4 Short Cuts

6 Comments

I’m very honored to be featured with my good friend Wlodek (US7IGN) in a short radio documentary on BBC Radio 4 today.

Wlodek is long-time reader and subscriber here on QRPer.com and the SWLing Post. Wlodek lives in Kiev, Ukraine and we keep in touch these days over email. Like me, he is passionate about field radio work and before the Russian invasion, you’d often find him in nearby forests experimenting with some pretty impressive field antennas.

Sadly, when Russia invaded Ukraine earlier this year, it very quickly brought an end to all of that for Wlod. Not only were amateur radio operators not allowed to transmit under the state of emergency, but it’s no longer safe to venture into nearby forests.

Radio producer, Cicely Fell, learned about our love of all things field radio and put together an audio piece that airs today on BBC Radio 4:

BBC Radio 4 Short Cuts

From the forests of North Carolina, USA to the city of Kyiv, Ukraine – two ham radio enthusiasts seek each other out and a voice from the past prompts a dialogue on listening between a rabbi and a radio producer.

Click here to listen via the BBC Radio 4 website (note that the audio can be streamed shortly after the program airs today).

Many thanks to Cicely and her talented team at Falling Tree Productions for spending a little time with us in the forest and on the air! Truly an honor.

A SOTA road trip from Berlin to Tuscany via the Alps and back

On the summit of Kellerjoch OE/TI-311

by Leo (DL2COM)

Flashback March 2021: I am sitting on a couch in the countryside 2h north of Berlin, Germany. It’s a rainy day and my 1-year-old kid just fell asleep on my chest. I am watching Youtube and enjoying the feeling of just having maintained the chainsaw after a productive run preparing firewood.

Then suddenly something special got washed into my feed: Adam K6ARK activating a summit in CW somewhere on the U.S. West Coast. I thought: I have no idea what this wizardry is but this is exactly what I want to do. Right here, right now. Well I have a child to take care of, the next mountain with a prominence of >150m (~500 feet, min. requirement to be a valid SOTA summit) is 3h away, I don’t know what ham radio is, I have no license and what the heck is CW.

Jump to July 2022: I am sitting in my car commencing a vacation road trip to the south of Tuscany, Italy. Due to the chaotic luggage situation at EU airports and unreal prices for rental cars my family and I had decided that we would be better off if I drove down while my wife and kids took the plane without having to check in any bags (btw: best decision ever).

Our schedule allowed for me to leave a few days early so I could make room to do a little bit of hiking and throw in a few casual SOTA activations because why not. On top I saw that there were a few never activated summits in close proximity to where we planned to stay. I could feel my heart pumping already followed by a strong reassuring feeling radiating from the well-thought-through contents of my backpack in the trunk. Am I ready? Who cares. I am on my own now. I had completed a quick 1-pointer activation in May and a few POTAs but what was planned now was a different level.

Going into detail about every summit would go beyond the scope of this article so here are just a few highlights: The first leg down to the Garmisch-Partenkirchen area went by in a wink (7h drive). I passed most of the time rehearsing CW by singing license plates out loud. The fun peaked with plates along the lines of M-OT-9990 or E-SI-5545. It’s all about melody and timing, remember. I met up with my buddy Chris whom I hadn’t seen in a long time and who agreed to join me on the first hike up Zirbelkopf (8-points summit) to witness the cult activity I had tried and failed to explain to him beforehand.

A challenging but fun POTA ATNO activation at Parc des Moulins

8 Comments

Some activations are more challenging than others.

I think we had all hoped on our climb into Cycle 25 that we’d get some brilliant propagation, stable conditions, and the opportunity to use less power and yield more DX.  Who doesn’t want that?

But we get what we get from our local star and the theme this year is that it is indeed showing some positive indicators, but at the same time–this summer, especially–it’s spitting stuff toward our pale blue dot that makes a mess of the ionosphere.

Lately, each time I head out the door to activate a park, I never know what to expect. It’s part of the fun. Will band conditions be in the dumps, or will the ionosphere provide the perfect platform for my QRP signals–?

On Thursday July 7, 2022 it was the former rather than the latter.

My family decided to head into Québec City that day to visit one of our favorite used book stores (in search of some Bandes Desinées–read more about that at the bottom of this post) and other errands.

I checked the POTA Map and discovered a park we’d never visited in the past, so it looked like a good candidate for a POTA activation!

Digging deeper, I also discovered it was an ATNO (All-Time New One) and had never been activated for POTA before. Hard to believe given its location, but there you go!

I put my POTA backpack in the car and we hit the road!

Parc des Moulins (VE-5068)

After a little searching, we finally found a good parking spot at the park. There was a LOT of construction going on around the grounds.

Parc des Moulins, like many of the parks I’d recently activated in/around Québec City, is a proper urban park with manicured paths and gardens. It’s a beautiful little park!

Joshua acquires an Argonaut 509

13 Comments

Many thanks to Joshua (KO4AWH) who shares the following guest post:

Ten-Tec Argonaut 509 Acquisition

by Joshua (KO4AWH)

My club president sent me a text on Sunday before our Monday club meeting. He wanted to know if I was interested in a Vintage 80s QRP Radio. He knows I have an affinity for QRP. Honestly, I think he is still amazed at how I managed to get through piles ups on his hexbeam during summer field day with my TX-500. Boy was that fun.

The deal was a Ten-Tec 509 with the microphone and CW filter, the matching 251 power supply with meter, and the 504 matching 50W amplifier. He sent me a photo, I had to look it up. I have heard of Ten-Tec, thanks to Thomas K4SWL, but certainly was not familiar with their Argonaut 509. I was intrigued. I don’t have a single vintage piece of equipment. I have only been a Ham for less than 3 years.

We had some equipment from a club member SK donated for auction to raise funds for some club repeater upgrades. This was a good excuse to purchase an old piece of equipment that I likely would not have purchased otherwise. After looking over the 509 and accessories, all of which were in great condition, I brought them home. Of course I couldn’t help but hook everything up and turn on power. Everything powered up but no movement of the frequency indicator, not a great sign, and no audible hint of changing reception frequency. After further inspection it seemed the dial tuning mechanism was seized up. Looks like another project.

The next morning, as I had a few minutes to spare I started taking things apart. I have never pulled apart an old transmitter before so I took my time as I studied all the components and marveled at the simplistic yet complex circuitry found under the covers. Once I was down to the tuning mechanism, a few desoldered wires later, it was removed and ready for cleaning. I don’t know if the grease was original, but it sure was hard. After carefully cleaning, greasing, and reassembling all the components, soldering a couple wires back, and reassembling the housing, I was ready to power it back up. I don’t want to understate the work involved, it can be quite tricky, but I really enjoy this type of thing.

After tuning around a bit and working with the controls on the Radio, I found a POTA operator to zero beat. I needed something to reference in order to adjust my knob indicator so I would know what frequency the radio is on. I actually received the manual for the radio and each of the components. Reading through a few key points the night before really helped out when I was ready to start tuning in and transmitting.

I had the amplifier on, I set the DRIVE to about half way guessing that was okay and called back to the Activator. First call, he called me back with a 59! WOW, I was excited. I let him know I was on an old Ten-Tec that I had just repaired and he came back and said the audio and signal were great. How exciting! So, naturally, I hunted a few more stations and then listened to a few rag chews as I got familiar with the Radio.

Not only was I excited to have repaired my first radio, I am also amazed at the capability of this Radio originally released in 1973. I am not a long time SWL or radio operator but there is certainly something very appealing to me about the audio this Rig produces. I wasn’t certain what I was getting into with this rig, but I sure am happy how it worked out! I may just be on the hunt for another Ten-Tec. I even plan to take this to my local park and do at least one activation with it.

Here is a quick excerpt from the introduction in the operating manual.

“The Argonaut opens a whole new world of excitement and fun in Amateur Radio. We think you will find QRP a welcome change. Five watts are only 2-1/2 S-units below 150 watts for the same conditions. When skip is favorable and QRM light, you will not be conscious of using low power.”

Side trail POTA ATNO at Boisé des Compagnons-de-Cartier in Québec City

7 Comments

On July 4, 2022, I plotted a multiple park POTA run that included four urban parks all clustered in the Sainte-Foy region of Québec City.

The first park I activated that day was Parc de la Plage-Jacques-Cartier (VE-0970)–click here to check out my full field report and activation video. The second park was Parc Cartier-Roberval (VE-0964)–click here to check out that field report and activation video. The third park was Boisé de Marly Provincial Park–click here to check out that field report and activation video.

My fourth park was Boisé des Compagnons-de-Cartier which essentially adjoined the previous park I activated. As I mentioned in the previous field report, I could have simply walked through the trail system to this park from my previous site, but I needed to find a different parking spot for my car, so I simply drove to a large lot next to the secondary school I spotted on Google Maps.

Turns out even though that lot was nearly empty, it was a paid parking, so I reserved a parking spot for one hour.

Boisé des Compagnons-de-Cartier (VE-0958)

When I first parked, I wasn’t entirely sure where the park entrance was until I spotted a bench and park sign at the far corner of the lot.

This park, much like the previous one, seemed to be an urban park with trails for walking and running.

I walked the main path into the park and looked for a park bench like I found at the park entrance (above). I thought it might be nice to set up along the path and do a park bench activation much like I did at another urban park in Québec City.

I walked for a decent distance and couldn’t see a bench in sight.  The path was fairly busy with walkers and runners, so I was very pleased when I found a side trail cutting through the middle of the park.

I could tell that this path–while very well-worn and obvious–was not one maintained by the park admin. It looked more like a simple foot trail that local children have probably used in the past (I spotted a little wooden fort/lean-to in the woods.)

Keep in mind that this was my fourth park activation of the day and by this time, I was running behind–no surprise there. After the activation, I had two errands to run in QC before heading back to our condo and enjoying dinner and a movie with the family.

Joshua’s ATU-10 review update after new firmware upgrades

2 Comments

Many thanks to Joshua (KO4AWH) who shares the following update to his previous guest review of the ATU-10 automatic antenna tuner:

Update on the ATU-10: new firmware released

by Joshua (KO4AWH)

The short story is that David N7DDC has a Firmware update with a new tuning algorithm that seems to fix the previously seen failure to find a decent match. As noted earlier in comparison with the Elecraft T1, the ATU-10 still does not necessarily get as close a match to 1:1 SWR but it now does indeed find a good match making this tuner my go to for use with my IC-705.

Not previously mentioned, the ATU-10 is also designed to work with the IC-705 for tuning commands when connected with a TRS 3.5mm cable, not just as an auto tuner when given a signal. And, in practice it works just as it should. I actually took the IC-705 and the ATU-10 and worked a SOTA/POTA with the beta version of this new firmware. I ran a 35’ wire and it worked great allowing me to work 40m, 20m, 15m and 6m for a total of 26 contacts. As a followup to my previous testing with the prior firmware 1.4, below are my results with the current new 1.5 firmware.

Testing on August 20th, 2022

The only difference from the original testing is the 31.5’ radiator was replaced with a 35’ and I did not tune and record results with the T1.

Conclusion on the ATU-10

I now feel very comfortable recommending this ATU. newdiytech.com has a great price and the build quality seems just fine. With the new algorithm update, a good match is found. The ATU-10 works great stand alone and also works fully automatically when used with a IC-705. This configuration means you can put the ATU at the antenna feed point and run a control cable back to the IC-705 and have a 50 ohm across the coax to help minimize loss, making for a nice portable setup with great band hopping flexibility.

Of course, if interested, I sell a protection cover for the ATU-10 just as I do for the T1.

If your curiosity is strong, here is some testing I did for David as he was updating the Algorithm now used in firmware 1.5.

UPDATE August 3rd 2022:

David Fainitski N7DDC has released a test firmware with a new tuning Algorithm with some promising initial results. A quick test on each band in the table has been added to reflect the new algorithm. This is not a firmware update yet but I suspect it will be soon. Results are great as tested. I hope to see this in a new FW soon.

August 6th, 2022

A second test firmware from David Fainitski N7DDC with the ability to increase or decrease the L and C manually allowed me to verify if a better match could be made. Turns out in a few cases it could. After testing again with a Tufteln 9:1 T80-2X2 on a 41ft sloping radiator I was able to achieve much better results than with the current version 1.4. In two cases I was able to find a better match manually. I realized later that if I were to tune a second time the ATU-10 would find the same, better match, on its own. Again, not a full firmware update, i.e. you have to flash back to 1.4 if you want to be able to turn off the turner.

(Click to enlarge.)

August 7th, 2022

Another test firmware David asked me to check. This version seemed more likely to find the best match. I did have the ATU go to L0, C0 twice but then find a match on a second try. This happened once on 40m and once on 10m. Almost like it faulted but there was some switching/clicking involved before stopping, it just landed at a 3:1 or higher with 0 for L and C. A second tune however straightened it out. I did not record those two cases. Below are the results. I was able to find a slightly better match twice but I am sure one would never notice the difference during normal use. The improvement both times was within the error of SWR across the three device measurements.

An Urban POTA ATNO at Boisé de Marly Provincial Park

10 Comments

I’m very grateful to Canada for taking me a little outside my comfort zone in terms of park activations.

You see, by and large, I activate large national and state parks in rural areas of the US. I’m used to having lots of space and loads of activation site options. Even on a busy day, if I choose, I can pretty much disappear in some far-flung corner of a park. No one would ever know I’m there.

Urban parks are still rather novel to me.

On July 4, 2022, I plotted a little multiple park POTA run that included four urban parks all clustered in the Sainte-Foy region of Québec City.

The first park I activated that day was Parc de la Plage-Jacques-Cartier (VE-0970)–click here to check out my full field report and activation video. The second park was Parc Cartier-Roberval (VE-0964)–click here to check out that field report and activation video.

The third park I scheduled for the day was Boisé de Marly Provincial Park. I could find very little information about this park online and even Google Maps satellite view didn’t give me an idea of what to expect once I arrived.

I could tell, though, that it was an urban park nestled between neighborhoods, roads, and commercial buildings. I could also tell that it had trees, so I planned to use the same transceiver-antenna pairing I used at the previous park: the Elecraft KX2 and Tufteln 9:1 random wire antenna.

Boisé de Marly was basically across the road from Parc Cartier-Roberval, but I needed to find a pedestrian access point and a parking spot, so I drove around the southern perimeter of the park until I found a side road with an access point and what appeared to be free parking on the road.

In truth, I wasn’t entirely sure if I needed a permit to park on the street, but I felt it was likely okay based on lack of signage. In any case, the street was quiet and I parked with a couple of other cars. I hoped that if I was mistaken, the person planning to write me a parking ticket would see my North Carolina plates and the RAC sticker and decide to give me a break. 🙂

Besides, at this point I was on a tight schedule if I wished to hit all four scheduled parks that afternoon, so I didn’t plan to hang around long enough for a ticket anyway.

Boisé de Marly (VE-0956)

At the neighborhood street entrance, I found the sign above that gave me a quick overview of the park. From what I could tell, this park primarily consisted of a trail network meant for walking and running.

I didn’t see any signs of picnic tables or even benches, at least at this end of the park.

I walked into the park maybe 100 meters or so and looked for a spot to operate.

QRP DX! Pairing the Elecraft KX2 & Tufteln Random Wire at Parc Cartier-Roberval.

4 Comments

On July 4, 2022, I plotted a little multiple park POTA run that included four parks all clustered in the Sainte-Foy region of Québec City.

The first park I activated that day was Parc de la Plage-Jacques-Cartier (VE-0970)–click here to check out my full field report and activation video. I managed to complete that activation in record time, during poor band conditions with the Elecraft AX1 antenna. In short? It was a blast!

I knew, however, that band conditions would likely only deteriorate that day and each subsequent activation could become more difficult to complete (spoiler alert: it did).

I scheduled Parc Cartier-Roberval (VE-0964) to be the second park of the day and was prepared to slog it out, but fortunately, the bands had not collapsed yet and this activation had a few surprises in store!

Parc Cartier-Roberval (VE-0964)

This park practically adjoins the previous park I activated. Indeed, if I had the time in my schedule (I did not) I would have walked the St. Lawrence river trail to Parc Cartier-Roberval.

My family actually visited Parc Cartier-Roberval the previous week while in the Sainte-Foy area.

The park is chock-full of history as it is also associated with an archaeological site exploring the first French colonists to arrive in America by Jacques Cartier and Jean-François de La Rocque de Roberval from 1541 to 1543.

There are some beautiful and informative displays on the west side of the park, near the railroad tracks.

There’s also a beautiful, immersive display that ends with a stunning overlook.

I could have spent all day soaking in the history.

The suspended glass encasement containing figurines of the first colonists is not to be missed.

And, again, the views from the overlook are most impressive!

Since I was on a schedule, I left the overlook and walked to the eastern part of the park.

When I visited the park the previous week, I had no time to perform an activation–in fact, we were in the Sainte-Foy area to visit a CLSC (regional medical center) and didn’t want to miss our appointment time.

Side note: Why were we visiting a CLSC the previous week? My wife cut her finger a few days prior; it was severe enough to require a visit to the hospital and six stitches. Our CLSC visit was to have a nurse check out her finger and change the bandage. The medical care we got was first class–within a week (two days after this activation) the stitches were removed and we were given the green light to do some camping up the north coast of the St. Lawrence. She had to change her bandages frequently for a full month, but looking at her finger now, you’d never know she’d cut it. Turns out, Québec is a great place to have a medical emergency!

But back to the activation…

Poor Propagation: Can the Elecraft AX1 handle band conditions during this urban POTA activation?

19 Comments

Typically, when I do field activations while on vacation, I squeeze them in and around our family activities and travels. This is quite easy to do because our family enjoys a good hike and we love our parks.

On July 4, 2022 (Independence Day in the US!) my wife and daughters had their own activities planned for the day which opened up nearly a full day–at least a good 5-6 hour window–for me to do park activations solo.

Château Frontenac in Old Québec

I had numerous park choices in/around Québec City–an area rich with POTA sites.

I thought that I could either spend the day hitting one park further afield or hit multiple parks clustered together.

I chose the latter, so I started researching the POTA Map for Québec City.

In truth, pretty much any of the parks in Québec City could have been pieced together for a multiple park run. In fact, there are a number cluster in the city center and in Old Québec, but I was keen to explore a little cluster of parks I noted in the Saint-Foy area west of Québec City:

The map below shows just how close these four parks are to each other. Very doable!

These parks were so close to each other, I considered parking in the middle and simply walking to each site, but after reviewing the distance between the potential activation sites at each parks more carefully, I realized I wouldn’t have the time to activate all four parks if I walked it.

It was this activation that reminded me how brilliant it would be to own a folding bike like by buddy Jim (N4JAW) uses on each of his nearly daily POTA activations. With a bicycle, I think I could have actually activated these more quickly than I could with a car because there’d be no need to find a parking spaces at each site.

The Plan

I decided I’d try to hit my four parks in this order:

The only park I’d visited in advance was Parc Cartier-Roberval so I knew I’d need a little time to find activation sites, etc. at the other three. If the activations took longer than expected to validate with 10 stations logged, I might have to skip the final park.

Interestingly, three of these four parks were ATNOs (All-Time New Ones) thus had never been activated for POTA. Continue reading Poor Propagation: Can the Elecraft AX1 handle band conditions during this urban POTA activation? →

Activating Parc National des Grands-Jardins as a POTA All-Time New One!

3 Comments

When I first started doing activations in the Parks On The Air (POTA) program, many of our regional parks in North Carolina were ATNOs (All-Time New Ones).

An ATNO is what it sounds like: a park that is in the POTA network but has never been activated.

ATNOs were plentiful in the early days–before the rise of POTA. In those early days, I found that if a park was even slightly inconvenient to access, it would be an ATNO.

In fact, I reckon that nearly 40% of the parks I activated in 2020, were ATNOs. This wasn’t because I made a particular effort to hit ATNOs. Rather I made an effort to activate unique parks that year; it was the beginning of the pandemic and this was a fun activity for me–an excuse to explore regional public lands–so ATNOs were among them.

With POTA participation having grown by orders of magnitude in the past few years–a very welcome thing indeed–ATNOs in North Carolina are extremely rare. I just checked and we have two ATNO parks out of 230 parks in NC. I can pretty much guarantee that our two ATNOs have either just been added to the database, or they’re very difficult to access.

POTA hasn’t been in Canada as long as it has in the US and, in some regions, it’s just catching on.

Another discovery was the Domaine de Maizerets–a very popular urban park in Québec City/Beauport that I activated as an ATNO in June 2022.

I was surprised to find that there were still a lot of ATNOs in/around Québec City because the area has a very active ham radio community.

Parc national des Grands-Jardins (VE-0499)

One of my favorite parks in Québec is Parc national des Grands-Jardins. This is a SEPAQ park located in the Charlevoix Biosphere Reserve.

As we were plotting our summer trip to Canada, I made a list of the parks I wanted to activate and Grands-Jardins was at the top of that list.

When we spend the summer in Québec, we always fit in a few visits to Grands-Jardins. The mountains there are beautiful with rounded tops and rocky faces. Via ferrata is a very popular summer activity in the park, but our family enjoys the hikes, the overlooks, and I especially love the back country roads!

I didn’t realize until a few days before attempting this activation that Grands-Jardins was still an ANTO!  Continue reading Activating Parc National des Grands-Jardins as a POTA All-Time New One! →
