POTA Field Report: Taking the LnR Precision LD-11 out for some fresh air

3 Comments

I mentioned in a previous post that I recently did a thorough clean-out of my shack and home office. It took two full days, and kept me out of the field during that time, but I’m very pleased with the results.

After re-arranging my grab-and-go QRP rigs on their dedicated shelf, one rig was very conspicuous: my LnR Precision LD-11.

Thinking back, it has been ages since I used it in the field–possibly more than a couple of years, in fact. As I packed my bags Sunday morning for a multi-day trip to my hometown, I grabbed the little red LD-11 and stuffed it in my main radio bag. It was time to take it to the field!

Lake James State Park (K-2739)

I didn’t have a lot of time to play radio Sunday afternoon, so Lake Jame State Park was a no-brainer. There, I know I have a number of picnic table options, mobile phone service, and it’s a modest detour off of Interstate 40. Low-hanging fruit in my POTA world.

There was snow on the ground Sunday afternoon, but it was 36F/2C so not terribly cold, just damp.

Due to snow melting in the trees, I set up my station in a picnic shelter where things were dry.

Gear:

Although I’d used the LD-11 recently at home to chase a few SOTA and POTA stations, I had not operated it intensively so it took a little time to reacquaint myself with this little rig.

It’s a gem of a transceiver and has a lot to offer in the field. If you’re interested to learn more about it, I’d encourage you to check out my original review of the LD-11 over at the SWLing Post.

Like the FT-817ND and G90, the LD-11 has no memory keying in CW or Phone. Memory keying is such a useful feature for park and summit activations because it frees up your fist and voice while calling CQ or sending 73s. With the LD-11, I’d be doing all of this “old school” which is absolutely fine for a short activation.

On the air

Although my EFT Trail-Friendly antenna should be resonant on 40, 20, and 10 meters, it was not Sunday because I’m almost certain I’ve finally damaged the radiator coil. I’ve deployed this antenna well over 150 times and yanked it out of countless trees when it got stuck. It’s lasted much longer than I would have ever guessed.

When I tried transmitting on 40 meters, I got a high SWR. Instead of replacing the antenna with another one, I simply hooked up the Elecraft T1 ATU and found a match. This is one good reason why you should always pack an antenna tuner. While employing an ATU might not be as efficient as using a resonant antenna, it can save your bacon in a situation like this and will certainly get the job done (especially if your only goal is a valid field activation).

After matching the antenna, I hopped on the 40M band and logged five CW stations in short order. Obviously, the antenna was working “well enough”–!

As I’ve done with a number of my recent activations, I started recording a video at this point.  I started it after my first five CW contacts due to a lack of space to record a 60 minute video (this one turned out to be 40 minutes and change).

I then moved up to the 20 meter band where I worked one CW station, then switched modes to SSB where I was surprised to work Jon (TI5JON) in Costa Rica, Steve (WA4TQS) in Texas, and Paul (NL7V) in North Pole, Alaska.

Video

This was one of those rare instances where my QRP SSB signal snagged more distant stations than my QRP CW signal.

I’m certain, however, had I spent more time on 20M CW, I would have logged a number of other distant contacts.  Here’s my QSOmap from the activation–not bad for 5 watts into an inefficient antenna:

All-in-all, I was very pleased with the activation. Even though I was making do with a faulty antenna and even though my CW was a little sloppy since I wasn’t quite used to the LD-11 keyer timing, it was so much fun!

I do love the little LD-11 and would certainly recommend grabbing a used one if you find a good deal.

As I mention in the video, the LD-11 is no longer manufactured and it never will be again. The main engineer behind the LD-11, SKY-SDR, and ALT-512–Dobri Hristov (LZ2TU)–passed away in 2020. Dobri was a well-respected fellow and distinguished ham radio operator/DXer. I corresponded with him quite a few times in the past. Sadly, when Dobri passed away, he took the design of all of these rigs with him. His brief period of sickness leading to his death all happened within a year.

So if you find one of these fine transceivers, keep in mind that some internal components (LCD screens, ICs, etc.) might be hard to replace if they fail. These radios are built well, however, so I wouldn’t expect something like that to happen for a very long time.

It was a lot of fun using the LD-11 during this activation and I certainly plan to put it in rotation from now on. Wherever Dobri is now, I like to think he’ll feel those LD-11 signals running through the ether!

Any other LD-11, SKY-SDR, or ALT-512 owners out there?  Please comment!

Many thanks to Don (W7SSB) who writes:

Thought you’d get a kick out of these products I used for ham radio in the field.


Out in the field you can protect not only your computer but your rig from the sun.

There are many models and they fold flat for easy handling.

Also you can get from a camping store a POTA party shelter for about $50 .

Great for a cheap portable ham shack . Keeps out of the sun and weather .

Room for a table, chair and cooler. What more do you need?

Have fun !

Don W7SSB

Thanks so much for the tip, Don!

It’s ironic you send this now as I’ve been looking at an inexpensive pop-up shade tent to protect my radios from the snow, sun and sand when doing portable operations. This $12 model (Amazon affiliate link) has been in my Amazon cart for about a week:

It’s made to protect a sun-bather’s head from the sun or protect a small pet. I think my gear could easily fit inside on a tabletop or ground and there’s even a small ceiling window (designed so people can look at their phones while sun bathing?!?) that I think would work brilliantly as a spot to place an LED light to illuminate the inside of the tent.

While I don’t think I’d use this a lot, it would be awfully handy when there’s no shelter from direct sunlight. It should keep a radio from over heating.

Also, recently I was operating outdoors with blowing snow–temps were well below freezing, but when snow landed on the transceiver, the chassis was warm enough to melt it. It started to get downright wet on top. A small pop-up like this would have come in handy.

Readers: Do you use pop-up shade products? Feel free to comment with your experience and share models you’ve used.

POTA Field Report: Pairing the Icom IC-705 with the Elecraft AX1 pocket antenna

3 Comments

I think I’ve said before that I don’t like doing things the easy way. At least, I’m coming to that conclusion.

This Saturday (Jan 30, 2021), I had a small window of opportunity to perform a Parks On The Air (POTA) activation.  My park options were limited because I needed to stay near my home and a store where I was scheduled to do a curbside pickup.

The only viable option–since time was a factor–was my reliable quick hit park.

The Blue Ridge Parkway (K-3378)

I plotted a quick trip to the Blue Ridge Parkway Folk Art Center which is centrally-located and, this time of year, there are few visitors.

But what radio take? It had been a couple of weeks since I used the IC-705 in the field, so I decided to take it and rely only on its supplied BP-272 battery pack.

My buddy Mike (K8RAT) had warned me only a few minutes before my departure that propagation was pretty much in the dumps. I’d also read numerous posts from QRPers trying to participate in the Winter Field Day event and finding conditions quite challenging.

Saturday was the sort of day that I should’ve deployed a resonant wire antenna and made the most of my meager five watts thus collect my required 10 contacts in short order.

And that’s exactly what I didn’t do.

You see, a really bad idea popped into my head that morning: I had a hankering to pair the IC-705 with my Elecraft AX1 super compact vertical antenna.

This made absolutely no sense.

I tried to get the idea out of my head, but the idea won. I suppose, at the end of the day, I’m not about taking the easy path (and I’m obviously a glutton for punishment).

I was also very curious if the mAT-705 Plus external ATU could tune the AX1 on 40 meters. More on that later…

Gear:

I arrived on site a few minutes before noon. Setup was fast–that’s the big positive about using the AX1.

Normally, I deploy the AX1 antenna with my KX2 or KX3 and simply attach it to the BNC connector on the side of the transceiver. The AX1 Bipod gives the antenna acceptable stability during operation.

The IC-705 also has a side-mounted BNC connector, but it’s much higher than that of the KX3 or KX2. I’m not entirely sure I could manipulate the Bipod legs to support the antenna without modification.

That and the AX1 needs an ATU to match 40 meters (where I planned to spend most of the activation). Since the IC-705 doesn’t have an internal ATU, mounting it to the side of the transceiver really wasn’t an option.

I employed my AX1 tripod mount for the first time. On the way out the door, I grabbed an old (heavy) tripod my father-in-law gave me some time ago and knew it would easily accommodate the super lightweight AX1.

On The Air

I first tried using the Mat-Tuner mAT-705 Plus ATU to tune the AX1 on 40 meters.

No go.

I tried both the phone and CW portions of the 40 meter band, but the mAT-705 Plus simply couldn’t find a match. SWR was north of 7:1 – 9:1.

Instead of grabbing the Chameleon MPAS Lite or 2.0 from the car, I decided instead to see if the Elecraft T1 ATU could tune 40 meters.

It did.

In short, I logged my ten contacts to have a valid activation, but it was slow-going. All but two of my contacts were on 40 meters CW. The last two logged were on 20 meters CW.

It was a challenge, but I really enjoyed it! And, frankly, considering the propagation, 5 watts of power only using the IC-705 battery pack, and the inherent inefficiencies using a loaded compact vertical antenna and ATU? I was impressed.

Here’s a QSOmap of my 10 contacts:

I bet my effective radiated power was closer to 2-3 watts.

Typically, the AX1 antenna acts almost like an NVIS antenna on 40 meters, but Saturday it favored Mid-Atlantic and the states of IN, OH, and PA. Normally, I would expect more of a showing from the states surrounding North Carolina.

My last two contacts on 20 meters were with KE5XV in Texas and KB0VXN in Minnesota. Not a bad hop!

It took longer to collect my ten contacts than I had hoped and I ran nearly 25 minutes late to my curbside appointment. I’m a punctual guy, but there was no way I was leaving without my ten! 🙂

Here’s a video of the entire activation. Hint: it’s the perfect remedy for insomnia:

Next time I try to pair the IC-705 with the AX1 antenna, I think I’ll try adding a couple more ground radials and see if the mAT-705 Plus can more easily find a match.

One thing I know for sure: the T1 is a brilliant little ATU. While the mAT-705 Plus was never designed to do this sort of match, it’s comforting to know the T1 can.

I’m very curious if anyone else has paired the Elecraft AX1 with the Icom IC-705 or other QRP transceivers. If so, what was your experience? Please comment!

POTA Field Report: Activating Lake James State Park (K-2739) with the Yaesu FT-817ND

4 Comments

One question that often faces newcomers to the hobby is: “Should I buy a QRP or a 100W transceiver as my first rig?”

That is a very deep topic, actually, and one to explore in a future post. A 100 watt transceiver will certainly give you more options as they can often pump out 100W or be turned down to 1 watt. If you’re a phone operator only, that’s got some serious appeal. Then again, if you’re operating POTA or SOTA where you are the DX, power–while still important–is much less so than, say, if you were at home trying to work DX.

Again, a deep topic for another post because there is no right or wrong answer.

One of our readers (Phillip) reached out to me a couple weeks ago and asked if the Yaesu FT-818 would make for a good first HF rig. He liked the portability factor, the build quality, the HF/VHF/UHF multi-mode coverage, and the overall flexibility of the rig as a field radio. His goal was to do POTA activations.

We had quite a few emails back and forth about the pros and cons and I decided it might make more sense to simply take my Yaesu FT-817ND (which is nearly identical to the FT-818) to the field and activate a park in both SSB and CW. Since I knew he wouldn’t necessarily have an external antenna tuner from day one, I paired the FT-817 with my resonant 40/20/10 meter end-fed antenna.

Lake James State Park (K-2739)

On January 17, 2021, I pulled into my favorite part of Lake James State park and quickly set up my station. I only had about one hour to complete my activation, so knew this would be a very brief excursion. Since I actually had a minimal amount of gear, it was a quick setup.

Gear:

Since I deployed a resonant antenna, there was no tuning or matching involved which not only makes the most of your 5 watts (in that it’s more efficient), but also saves a bit of time in set up and tuning up.

You might note in the video below that my FT-817 has an accessory board attached to the top: G7UHN’s 817 Buddy Board prototype.

I’m testing this prototype at the moment, but didn’t need to employ it at Lake James since it’s really useful when the rig is on your lap or on on the ground. It essentially gives you top-mounted controls and a larger display to read front panel information from above–incredibly useful for SOTA and proper in-the-field activations. Andy’s v3 board will include a memory keyer–I can’t wait for that one!

Since I had Internet access at this park, I used my Microsoft Surface Go logging tablet to spot myself to the POTA network. I started calling CQ on 40 meters phone (SSB) and within six minutes logged eight stations. Not bad for 5 watts and a wire!

Next, I moved to CW on 40 meters and started calling CQ POTA. The POTA spots page auto-spotted me via the Reverse Beacon Network in short order. In eight minutes, I worked six more stations.

I then moved to twenty meters which was essentially dead, so I called it quits a bit early. I needed to pack up and head to my next destination.

Here’s a QSOMap of this short activation (red polylines are SSB and green CW):

I also made one of my real-time real-life no edit videos during this activation if you’re interested:

Truth is, each time I use the FT-817, I love it more. Sure it’s only 5 watts, has no ATU, has a small display, a clicky T/R relay, and questionable ergonomics, but it is a keeper for sure. Even after 20 years of being in production, it still holds its own and is an incredibly popular radio for good reason.

As I told Phillip, the 817/818 is the Toyota Corolla of the QRP radio world.

POTA Field Report: Three watts, cold winds, and how *not* to calculate antenna length

4 Comments

Last week, I activated Pisgah Game Land and Pisgah National Forest (K-6937 & K-4510)–things didn’t exactly go according to plan.  I still achieved a valid activations–meaning, I logged ten contacts–but I cut my antenna too short.

I this previous post, I describe my mistake and the lesson learned that day.

In short: I cut my wire antenna too short and my KX1 and KX2 ATUs couldn’t find an acceptable impedance match on the 40 meter band. This pretty much forced me to make do with 30 meters and above unless I modified or switched antennas.

The 40 meter band tends to be my most productive band, particularly on days like last Saturday when I’m operating in the latter part of the afternoon.

Maybe it was stubbornness, but I was determined to make a valid activation with that four-feet-too-short antenna.

Gear:

I first hopped on the air with my Elecraft KX1 (above) and logged a few contacts on 30 meters. I then tried 20 meters, but the band was dead.

Eventually, I pulled the Elecraft KX2 out of the bag with the hope it might actually find a match on 40 meters, but as I said in my previous post, that darn physics stuff got in the way.

That’s okay, though. Although the sun was starting to set and I didn’t want to pack up in the dark, I took my time and eventually logged ten contacts for a valid activation. I actually enjoyed the challenge.

I complain about my wire antenna, but in the end, it made the most of my three watts by snagging stations from New Hampshire, Ontario, Illinois, Arkansas and several states in between.

Against my better judgement, I made a video of this activation. As with all of my videos, they’re real-time, real-life, and have no edits. (They also have no ads.)

A few readers and subscribers had asked me to include the odd video where I actually do a full station set up including the installation of a wire antenna–that’s what you’ll see in this video:

At the end of the day, this was still an incredibly fun activation.

This was the first time I’ve ever completed a valid activation only using the 30 meter band.

Next time, though, you’d better believe I’ll cut my antenna to be the ideal length for 40 meters and above!

How long?

If you use a similar antenna with your KX1, KX2, KX3, or other transceiver, I’m curious what lengths you find work best for 40 meters an above. Bonus points for 80 meters. Please comment!

Parks On The Air Pro Tip: Finding more park sites to activate

5 Comments

Many thanks to QRPer, Curt, who recently left the following comment on a recent post and noted:

I too was a NPOTA activator. My first HF contact ever was on 9/10/2016 and then I threw myself to the wolves so to speak activating my first park on 11/12/2016.

When NPOTA was over I went into withdrawal and I thought POTA was going to fill that void but here in Western PA there’s not much to pick from. We have a lot of parks but none that fall into the park list. One of the local parks I’ve been told not to bother because it’s in the middle of the city and the local police don’t seem to like any activations there for whatever reason.[…]

You’re right, Curt, and I totally understand.  Many local, county, and private parks are not included in the Parks On The Air (POTA) program. POTA tends to include parks that are on a state, provincial, or national level. Not always in every country, but it’s the general rule of thumb.

I don’t know the POTA scene in western PA well because I’ve never thoroughly researched it. With that said, I’m willing to bet there are more accessible parks in your neck of the woods than you might realize at first blush.

The only entry to this state park is very easy to find and marked well along the highway.

Historic sites and parks–both state and national ones–tend to have very defined borders with conspicuous entry points. They’re, in many senses, “low-hanging fruit” for POTA because they’re super easy to find and usually have picnic and camping areas.

You simply locate one on the POTA map, tell your smart phone to take you there, arrive, find a picnic table or parking area near trees, setup,…et voilá! You’re on the air and activating. Typically, a very straight-forward process.

I would suggest new POTA operators start with these types of parks to give their field radio kit a good shake-out.

Digging deeper…

There are so many other POTA entities out there, though, and the POTA map (while an excellent resource) can’t represent them well.

I should add here, that POTA is an international radio activity and I do not know the various types of parks and POTA entities in other countries. There’s a lot of variability.

Here in the States, aside from parks and historic sites, we have other POTA entities like:

  • Game Lands
  • Rivers
  • Trails
  • Wildlife Management Areas & Refuges
  • Recreation areas
  • Conservation areas
  • and Forests

These types of public lands can be vast with many possible parking areas and entry points. Some have multiple, disconnected tracts of land and the POTA map only typically represents them as one clickable geo point because it would be incredibly difficult to represent them otherwise.

It requires the POTA activator to do a little planning and research.

One example

Here in North Carolina, we have a lot of state game lands and they’re some of my favorite spots to activate.

Some game lands may only be a couple hundred acres large, others may encompass hundreds of thousands of acres.

Case in Point: Nantahala Game Land is only one entity on the POTA map, but it is located in no less than six western North Carolina counties–dominating the majority of them, in fact.

Check out this map of Nantahala Game Land from the NC WRC website below:

Click to enlarge.

There are probably hundreds of spots where you can find public access to activate this particular POTA park.

Trails are another POTA entity that should not be overlooked. They often snake through areas and have multiple trailheads where you can easily find parking and ample room to activate.

Here’s how I find the more elusive POTA parks…

Being a bit of a map geek, I actually love this process!

1. Take a close look at the POTA list

The POTA map is amazing, but as I said, it simply can’t display the size and geographic shape of each park.

Start with the complete list of POTA entities in your location.

An example from Pennsylvania.

Click here to display a list of all POTA entities at your location.

If you have lived the majority of your life where you are now, you’ll likely recognize some of the names associated with the park entities in this list.

Regardless, comb through this long list carefully. Do an internet search on the park names and you’ll quickly discover roughly where the land is located

2. Make a spreadsheet of potential parks

A sample of my park spreadsheet from early last year.

On this sheet make column headers for at least:

  • The park name
  • The POTA designator for that park (K-6937, for example)
  • The travel time to the park
  • The geo coordinates of potential activation spots

I also added

  • How “rare” the park might be (how many times it’s been activated)
  • How easy access to the park might be
  • If it could potentially be a two-fer (meaning two POTA entities overlapping)

3.) Find an activation site with Google Maps satellite view

Now that you’re developing an activation plan (via your spreadsheet), and you’ve located all of the nearby parks, game lands, wildlife management areas, trails, refuges, etc. it’s time to research each entity and find activation sites.

Most states (and provinces, counties, regions) have sites that will help you find access points to public lands. Each state is different–some (like North Carolina) have amazing online resources, others may not.

If you can’t get the details you need online, don’t hesitate to call those public departments in charge of the lands and ask them about access points. They’re experts on the subject and often your taxes pay their salary. 🙂

To find game land activation sites in North Carolina, I first go to the WRC Map and click on a site. The WRC site will offer up maps and even indicate obvious parking and camping locations.

I then find public roads in/around the game lands and do a Google Map search (you can pick your favorite mapping tool).

I compare the WRC map with the Google map (side by side) and search for parking spots using a satellite view.

Here’s how to find the satellite view on Google Maps using a sample POTA site:

Find the park area based on public roads, then click on satellite view:

Now you’ll be able to see a bird’s eye view of the land:

When you zoom in, you often can identify a nice parking spot:

Using the satellite view I can zoom in and see that there’s a parking space with trees surrounding it. Score!

That’s how I do it.

Important note: of course, it’s incredibly important that you compare public land boundaries with your activation site and make sure you will, indeed, be on that POTA entity when you activate. While there are no POTA police–nor will there ever be–I personally want to be 100% sure I’m activating entirely within the boundaries of my chosen park. Google Maps can’t be trusted to indicate unit boundaries–one needs to compare the state or federal maps of the unit to be sure.

Next, I take those geo coordinates (map links) and embed them in my POTA spreadsheet.

Later on, when I decide to activate that park, all of my research is done! I simply grab my gear and go.

That’s it!

If you’re like me, you may be surprised how many potential activation sites there are in your region when you take a closer look at public land boundaries and access points.

I found at least five POTA sites within a 90 minute drive of my home that were ATNOs (All-Time New Ones) that no one had activated.

How do you research parks–?

I probably should not call this a “Pro Tip” because I’m not a professional!

There are many different ways you can find great POTA sites within your region. Please feel free to share your POTA procedure with us in the comments!

POTA Field Report: Pairing the Elecraft KX3 with the AX1 antenna and seeking distant stations

16 Comments

Although I’m a huge fan of wire antennas in the field, since I started using CW during my Parks On The Air (POTA) activations, I’ve really enjoyed experimenting with compromised portable antennas.

Typically, there’s a trade off with field antennas:

High-performance antennas tend to take more time to install. Some of my highest performance antennas are dipoles, doublets, delta loops, and end fed wire antennas. All of them require support from a tree if I want maximum height off the ground. Some (like the dipole) require multiple supports. While I actually enjoy installing wire antennas in trees, it typically takes me at least 10 minutes to install a wire antenna if it only needs one support and one counterpoise.

Compromised or low-profile antennas may lack performance and efficiency, but are often much quicker and easier to deploy.

In my opinion, field operators should keep both types of antennas in their arsenal because sometimes the site itself will dictate which antenna they use. I’ve activated many sites where wire antennas simply aren’t an option.

That was not the case last Tuesday, however.

Tuttle Educational State Forest (K-4861)

On Tuesday, December 29, 2020, I stopped by Tuttle Educational State Forest (K-4861)–one of my favorite local state parks–for a quick, impromptu activation.

I had no less than four antennas in my car that day and Tuttle is the type of site where I can install pretty much anything: they’ve a spacious picnic area with large tables, tall trees, and parking is close by. Tuttle is the perfect place to deploy not only a large wire antenna, but a large radio if you wish since you don’t have to lug it far from the car.

But en route to Tuttle I decided to take a completely different approach. One of the four antennas I had in the car that day was the Elecraft AX1 antenna.

Without a doubt, the AX1 is the most portable antenna I own. It’s so compact, I can carry it in my pocket if I wish.

When I first purchased the AX1, I was very skeptical and assumed it would only work when “the stars aligned”–days with better-than-average propagation and lots of POTA hunters/chasers looking for me.

The first time I used the AX1 in the field, it impressed me (understatement alert).

The second time, same thing.

In all of my AX1 activations, however, I had only operated on the 40 meter band where the antenna’s footprint looked more like a NVIS antenna than a vertical. Meaning, most of my contacts were in neighboring states like Tennessee, South Carolina, Virginia, and Georgia (typically, those states are in my 40 meter skip zone).

The reason I hadn’t tried 20 or 17 meters with the AX1 is because I would start an activation on the 40 meter band and accumulate enough contacts to achieve a valid activation. Since I’m often pressed for time, I simply didn’t bother configuring the antenna for the higher bands.

Time for that to change!

The question I wanted answered at Tuttle: could the AX1 antenna work “DX” stations? By DX, I mean POTA DX, so distant states and provinces primarily–not necessarily other countries.

Gear:

On the air

I paired the Elecraft KX3 with the AX1 at Tuttle. This was the first time I’d ever tried this particular transceiver/antenna combo.

After setting up, I started on the 20 meter band and called CQ for a few minutes.

The first two stations I worked were in Texas (KF9RX and K5RX).

The third station (W6LEN) was in California.

California!?!

Honestly, it was/is hard for me to fathom how in the world 10 watts into a tabletop telescoping whip antenna could work a station exactly 2,083 miles (3,352 km)–and three time zones away–from my picnic table. I’m sure W6LEN has a great antenna on the other end, but I bet he would be surprised to learn that my 10 watt signal was being radiated by such a wee antenna.

 

 

I then worked stations in Florida (K2WO), Minnesota (N0UR), and New Hampshire (W2NR) and decided to move to 17 meters.

On 17 meters I worked W2NR in New Hampshire once again.

I should note here that each time you work a station on a different band or with a different mode, it counts as a separate contact in POTA. In other words, my contacts with W2NR on 20 meters and 17 meters counts as two logged contacts toward my overall QSO count. I’m very appreciative of hunters who go out of their way to work me on different bands and modes: those extra contacts help me achieve a valid activation in short order.

I then moved to 40 meters and worked stations from Tennessee, West Virginia, Ohio, and Michigan.

Video

Here’s a video of the entire activation. It’s a long video as it starts at set-up and continues until my last contact. There are no edits in this video–it’s a real-time, real-life deal and contains all of my bloopers:

Note that in the video I had the KX3’s volume maxed out so that it could be picked up by my iPhone microphone. The KX3’s wee internal speaker was vibrating the chassis ever so slightly. On the 40 meter band, it resonated enough that it moved the encoder slightly. Next time, I’ll plan to bring a portable external speaker (if you have any suggestions of good ones, let me know).

And here’s a QSOmap of the activation:

Bioenno 3aH LiFePo battery

I should also add that I’m very pleased with my new Bioenno 3aH LiFePo 12V battery. You can see it in the photo above–it’s slim, lightweight, and very compact.

I purchased it during Bioenno’s Black Friday sale. I was a little concerned it might not have enough capacity to carry me through multiple activations–my other LiFePo batteries re 4.5 and 15 aH–but that does not seem to be the case at all! Not only did it provide nearly an hour of intense use on this activation, but it also powered three activations the previous day–all four activations on one charge! Brilliant!

Radio magic

As I mentioned in a previous post, this was one of those activations that reminded me of the magic of low-power radio. It was incredibly fun!

For all of those phone/SSB operators out there, I will eventually see how successful I can be doing a phone-only activation with the AX1 antenna. I’ll plan to make a video of it as well. I’ll need to plan this for a day when I have more time to spend on the air and at a site where I know I’ll have internet access to spot myself to the POTA network.  SSB isn’t quite as effective as CW when operating with a setup this modest. Still–it can be done! It just requires a little more patience. Please let me know if this sort of thing would interest you.

Until then, Happy New Year and 73s to everyone!

Should I sell my Elecraft KXPA100?

16 Comments

Although I’m at heart a QRPer, I do occasionally serve up more than 5 watts. It’s rare, though.

A few years ago, I purchased an Elecraft KXPA100 amplifier with the optional built-in ATU. I did this in lieu of considering a 100 watt rig since, at the time, I had no 100 watt transceivers.

My thinking was the KXPA100 could serve both my Elecraft KX3 and KX2–pushing them into 100 watts of service when needed. The KXPA100 is also super portable and operates quietly (no fans).

I purchased the KXPA100, connected it to my KX3 in the shack, and then barely used it.

Last year, I realized the KXPA100 could serve me well during Parks On The Air (POTA) activations when conditions were poor for SSB (they were very poor at times in the spring and summer) so I took it to the field a few times. That was before I started using CW during my activations, though.

Since I’ve started using CW, I haven’t taken the KXPA100 to the field once. I also haven’t used it in the shack since then.

I do now have other QRO radios at my disposal: the Icom IC-756 Pro my buddy Matt so kindly gave me in 2019, and the Mission RGO One transceiver I continue to test and evaluate for the manufacturer.

The KXPA100 is unique in that it can pair with almost any QRP radio. I do like that fact because I’ve a lot of QRP transceivers.

These days, about the only time I run anything north of 10 watts is to possibly chase weak signal DX or participate in contests like the 13 Colonies event where I’m up against blowtorch stations in SSB.  I tend to do that at the QTH, not in the field.

Should it stay or should it go?

The only reasons I feel I should keep the KXPA100 is because, in my mind, I feel like it essentially turns my KX3 into a poor man’s K3. It can also directly connect to my KX2 and even the FT-817ND via a command cable for seamless control. That and, occasionally, there may be a good reason to take it to the field.

Still: I feel like if I’m not using it, I should sell it to someone who can. It would also free up $900 or so to re-invest into my gear. That would certainly come in handy!

I would appreciate your thoughts and comments.

The magic of low-power amateur radio never dies

1 Comment

I’ll keep this post short and sweet because I plan to write up a full field report with video sometime next week.

Tuesday (December 29, 2020), I fit in an impromptu Parks On The Air (POTA) activation in the afternoon. The station was very modest: basically, my Elecraft KX3 paired with the super compact Elecraft AX1 antenna.

Here’s what I did with 10 watts and a wee telescoping whip during mediocre propagation:

I got a huge thrill out of this.

Honestly, this hobby never gets old and I honestly believe there’s magic in QRP!

Here’s wishing everyone a safe, healthy and happy New Year!

POTA Field Report: Three park run with two transceivers & two antennas

4 Comments

Yesterday, I started the day hoping I might fit in one afternoon activation at a local park. In the morning, however, my schedule opened up and I found I actually had a window of about six hours to play radio!

Instead of hitting a local park, I considered driving to parks I’d been planning to activate for months.

I may have mentioned before that, earlier this year, I created a spreadsheet where I listed of all of the parks I planned to activate in 2020.

From earlier this year–many of the parks listed as “rare” are much less so now!

Each park entry had the park name, POTA designator, priority (high/medium/low), difficulty level for access, and a link to the geo coordinates of where I could park and possibly hike to the site. I spent hours putting that list together as finding park access–especially for game lands–isn’t always easy.

Yesterday morning, I looked at that sheet and decided to knock two, or possibly three off the list.

I had already plotted the park run, driving to Perkins State Game Land (K-6935) near Mocksville, then to the NC Transportation Museum State Historic Site (K-6847) in Spencer, and finally Second Creek Game Land (K-6950) in Mt Ulla.

The circuit required about three hours of driving. Here’s the map:
When I plan an activation run, I factor in the travel time, add ten minutes extra if it’s my first time at the site (assuming I’ll need to find a spot to operate) and then assume at least one hour to deploy my gear, work at least ten stations, and pack up.

Using this formula, I’d need to allow three hours for driving, plus an additional three hours of operating time, plus a few minutes to sort out an operating spot at Perkins Game Land. That would total six hours and some change.

Knowing things don’t always go to plan, I decided I’d quickly omit the NC Transportation museum if I was running behind after the Perkins activation. In fact, I felt like the NC Transportation Museum  might be out of reach, so I didn’t even schedule the activation on the POTA site.

Perkins State Game Land (K-6935)

I arrived at K-6935 a little before noon (EST).

Since this is the week after Christmas, I had a hunch game lands could be quite busy with folks trying out their new hunting gear and I was correct.  I passed by the first small parking area and it was packed with vehicles, so I drove on to the second parking area I identified via Google Maps satellite view.

The second parking area was also busy, but was larger. There was just enough room for my car to park between two trucks.

Gear:

I donned my blaze orange vest–a necessity at any game land–and walked outside to asses the site. In short? It was a tough one. There were no easy trees to use for antenna support and I simply didn’t have the space. I knew folks would walk through the area where I set up my antenna so a wire antenna would have acted a lot like a spider’s web.

I pulled out my trust Chameleon MPAS Lite vertical antenna and deployed it next to the car. I rolled out the counterpoise into the woods paralleling a footpath so no one would trip on it.

Since I had no room to set up outside, I operated from the backseat of my car–it was actually very comfortable.

I pulled out the Elecraft KX3 and hooked it directly to the MPAS Lite–it easily tuned the antenna on both 40 meters, where I started, then later 20 meters.

I very quickly logged 13 stations on 40 and 20 meters.

While on the air, a number of other hunters discovered the parking area was nearly full–some turned around and left. I decided to cut the activation with 13 logged and skipped doing any SSB work. I accomplished what I set out to do here, was short on time, and I wasn’t actually using the game land for its intended purpose. Better to give others the parking space!

I quickly packed up and started the 30 minute drive to my next site.

NC Transportation Museum State Historic Site (K-6847)

The Cameleon MPAS Lite

I knew what to expect at the NC Transportation Museum because I’ve visited the museum in the past and, earlier this year, scoped out a spot to activate the park in their overflow parking area.

The museum is closed on Mondays. In general, I avoid activating parks and sites that are closed. I never want to give anyone at the park a bad impression of POTA activators.

In this case, however, the overflow parking area is wide open even when the park is closed and there was no one at the site. I felt very comfortable setting up the CHA MPAS Lite which is a pretty stealthy antenna. Indeed, as I was setting up, I’m guessing it was a museum employee that passed by in their car and waved–no doubt, POTA activators are a familiar site!

Gear:

I set up my portable table behind the car under the hatchback so I took up the least amount of space.

I used the table primarily so I could shoot one of my real-time, real-life videos of a park activation. Readers have been asking for more of these and I’m happy to make them if they’re helpful to even one new ham.

In the end, I logged 13 stations and didn’t try to work more because I was still on track to activate one more park. I didn’t feel bad about only working 13 stations, because this site has been activated many times in the past–in other words, it wasn’t exactly rare.

Here’s my video of the activation:

Second Creek Game Land (K-6950)

The Cameleon MPAS 2.0

I arrived at K-6950, the final park, around 14:50 EST (19:50 UTC).

Only one vehicle car was in the parking area, so it was easy to pick out a spot to set up.

Gear:

Again, since I planned to make a video of the activation, I set up my portable table.

I decided en route to the site, that I’d use the Chameleon MPAS 2.0 vertical at Second Creek. Although I’ve used the more compact Chameleon MPAS Lite at a number of parks–including the two previous parks–I had a great spot to deploy the taller MPAS 2.0.

As with the MPAS Lite, deployment was very quick. the MPAS 2.0 vertical is made up of folding pole sections–much like tent poles. As with all Chameleon gear I’ve ever used, the quality is military grade. Full stop.

I started calling CQ on the 20 meter band in CW this time. Within a minute or so I logged my first contact, followed by five more.

I then moved to the 40 meter band and logged twelve more stations in twelve minutes.

I decided to then give SSB a go as well and logged two more stations for a total of twenty stations logged.

Here’s a video of the activation:

I would like to have stayed longer at Second Creek and even used the MPAS 2.0 on 80 meters, but frankly I was pushing my time limit to the edge.

All in all, it was a brilliant three park run!

These days, it’s difficult to pack more than three parks in my available time–in fact, I think this was the first three park run I’d done in months. During National Parks On The Air (NPOTA) in 2016, I’d been known to pack four or five parks in a day–it was so much fun.

Here’s my QSOmap for the day (click to enlarge):

Getting outside on such a beautiful day, driving through some picturesque rural parts of my home state, and playing radio? Yeah, that’s always going to be a formula for some amazing fun!
