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

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!

Pairing the Elecraft K2 with the AX1 at Tuttle for some QRP P2P DX!

If you recall from my last field report, I’ve been pairing the Elecraft AX1 antenna with a number of radios. For me, it’s been a fun exercise because I always enjoy seeing what sort of results the AX1 might produce. So far, it has never disappointed.

On Thursday, February 2, 2023, I packed two radios in my car with the idea of fitting in two consecutive park activations.

At my first activation of the day–Lake James State Park–I paired the AX1 with my Mission RGO One transceiver. The activation was a blast! Not only did I stay busy working stations, but I also managed a little QRP DX thanks to a hunter from Italy.

K2 and AX1 Under Shelter

Little Guatemala Café

After grabbing a curried chicken salad wrap at Food Matters and a coffee at Little Guatemala roasters in Morganton, I hit my second and final park of the day: Tuttle Educational State Forest (K-4861). It was rainy, so the park was empty which allowed me to take over the very large picnic shelter at Tuttle.

Even though this particular shelter is in a bit of a dip in the land and has a large metal roof, I’ve had successful activations there in the past employing the AX1 antenna.

My hope was that history would repeat itself!

Setting Up

Attaching the AX1 antenna to the back of the Elecraft K2 was not complicated because the K2 has a BNC connector with nothing protruding to get in the way of the Bipod. Continue reading Pairing the Elecraft K2 with the AX1 at Tuttle for some QRP P2P DX!

Elecraft AX1 Test Using American Radio Supply AM-801 Window Mount

AX1 Test using American Radio Supply AM-801 Window Mount: POTA Activation at Stuart B. McKinney Wildlife Refuge, K-0228

February 19, 2023

By: Conrad Trautmann (N2YCH)

If you’ve been reading the posts here on QRPer.com lately, you probably already know that the Elecraft AX1 has proven to be an excellent antenna for POTA activations for CW, SSB and Digital modes.

Personally, I used it for a New York City POTA rove I did at the end of 2022 and was able to activate four parks in one day all over Manhattan.

Recently, Alan, W2AEW contributed a story to QRPer.com detailing how he used a window bracket he constructed with an AX1 to do a CW park activation from his car. I’ve actually done a few digital activations from the car using the AX1, however, I used the tripod with the Elecraft tripod adapter and ran coax to it out the window and draped the counterpoise down the hood or trunk. This has worked well except for windy days where it would blow over. I was intrigued by the possibility of using the window mount and a number of the commenters to Alan’s post suggested sources for these types of mounts. I ended up ordering an AM-801 from American Radio Supply.

https://www.americanradiosupply.com/am-801-window-antenna-mount-bnc-connectors/

Since the AX1 depends on a counterpoise wire to operate properly, the first thing I did after receiving the AM-801 mount was to drill a hole in the base for a screw and a wing nut. The base is painted black, so I got my continuity meter out to double check that the screw was making a good ground, which it was. I had to bend the mount up slightly for the antenna to be vertical, since my Jeep windows don’t have much of an angle to them. I’m sure it would be just right for most cars.

My next step was to give it a try. Continue reading Elecraft AX1 Test Using American Radio Supply AM-801 Window Mount

Postcard Field Report: Pairing the Mission RGO One with the Elecraft AX1 at Lake James for some QRP DX

Welcome to my first Postcard Field Report!

If you’ve been following QRPer.com and my YouTube channel for long, you’ll notice that I typically post two field reports with videos per week when my free time allows. Each report takes about four hours to produce along with a video. I’ve currently got a small backlog of videos I need to post, so in order to squeeze them into my schedule, I’m going to use a slightly more abbreviated field report format: a “postcard” format!

My Postcard Field Reports will still be information-packed, just slightly more concise and distilled than my average field report. I’ll primarily post these for sites I visit frequently.

Speaking of which….

Lake James State Park (K-2739)

Thursday, February 2, 2023, was a rainy, dreary day so the perfect time to play a little POTA, right?  I made time in my morning to visit Lake James State Park (K-2739).

When I arrived at the Catawba River Access, the parking lot was empty. Not too surprising considering it was a Thursday morning on a chilly, rainy day.

Of course, I had the picnic shelter all to myself, so why not use it to stay dry? Continue reading Postcard Field Report: Pairing the Mission RGO One with the Elecraft AX1 at Lake James for some QRP DX

VE6LK: Antenna tuning on Superb Owl Sunday

Antenna tuning on Superb Owl Sunday

by Vince (VE6LK)

While many in North America were watching a number of Superb Owls move a pigskin around a playing field, I was off to play radio, successfully, for the first time in weeks. This is part of my goal to activate 200 CW POTA contacts per month this year.

During recent visit to Vancouver attempting to operate from within my hotel room, and utilizing the Edisonian Approach, I was shown -more than once- what did not work. This will no doubt be a discussion point on an upcoming Ham Radio Workbench Podcast. I was therefore in very bad need to get back on the air while operating portable. I was close to feeling twitchy and in need of some POTAXXIA (Hyperradio Moduzolium). A plan was needed!

My goals were to trim out a new-to-me EFHW (thanks VE6VID), and make some contacts while operating outdoors. The weather was forecast for 50F, but turned out to be unexpectedly windy. Also, when the wind comes off the Canadian Rockies in Southern Alberta, it cools the area where I’d be (downwind), so a choice of operating location was key. I love going to this park for the moment that you drive west along Highway 533 and come around the corner as you see here in this short video.

Chain Lakes Provincial Park (VE-1168) is located between the Porcupine Hills and the Rockies on Highway 22 (locally known as the Cowboy Trail) in Southern Alberta, about 90 minutes south of Calgary. It’s especially gorgeous at sunrise and sunsets. A campground, lake with boat launch and a day use area all adorn this park created for water management with an earthen dam. While it is in a valley, the wind can be howling on some days. On this day it would prove to be just above a nuisance, sort of like mosquitos in the spring -you can live with the nuisance, but only for so long before you blow a proverbial gasket.

Short video – beautiful site and babbling brook

I located a lovely spot below the dam -and the majority of the wind- however it was outside of cellular range. I’d need to rely on the Reverse Beacon Network to spot me. The RBN will, in turn, post your spot to the POTA website once it hears you if you schedule your activation in advance.

The place I found would only be more perfect were it warmer than 45F and without wind. A babbling brook was by the picnic table, and a nearby footbridge had built-in supports for my painter’s pole that would serve as the far end support. I’m pretty sure that they weren’t intended for me specifically, but they were the perfect size to simply slide the pole into place and hold it firmly. By luck I parked the truck the correct distance away with it’s drive-on mount and 28′ Fibreglass Flagpole from Flagpoles-To-Go via Amazon. Continue reading VE6LK: Antenna tuning on Superb Owl Sunday

Brian puts a new antenna to the test during Winter Field Day!

A shelter for Winter Field Day operations in a field

Field Report:  Winter Field Day with a New Antenna

Winter Field Day (WFD) 2022 found me operating indoors, despite my best intentions to get out in the field.  I was recovering from a bad cold, and did not want to risk having complications arise from sitting out in the cold and damp.  So for WFD 2023, outdoor time with my radio was a must.  I wanted to operate a 1-Oscar station, and to do that I had to set up more than 500 feet from my home QTH.  So a site next to the pond in our back field, about 800 feet from the house, became my WFD shack.

I started planning and collecting kit for the operation in mid-January, with the long term forecast hinting at near-freezing temperatures with the potential for rain or snow.  Let me introduce you to my WFD station.

Shelter

A shelter was needed to keep out rain and snow, and to provide a barrier against the winds whipping across the adjacent field.  A few poles lashed together, and steadied by stakes, provided the frame to support the shelter.  With a poly tarp secured to this frame, the resulting a-frame shelter, while not completely enclosed, did provide effective weather protection for both operator and equipment.  There was about 3 inches of snow on the ground when I set up the shelter, and I was able to pile some of it along the bottom edge of the tarp to keep the wind from getting under it.

A-frame shelter constructed of a poly tarp stretched over a frame of poles

Antenna

I know that when setting up a station, the antenna is not generally the first thought, but I had recently finished building a homebrew 9:1 random wire antenna with a 144 ft radiating wire, and I wanted to test it out.  There are better ways to put a new antenna on the air, but the opportunity was a good one.  Besides, I had backup antennas that could be quickly substituted if the need arose.  In the event, things worked well, and the antenna proved agile and capable on all activated bands.  I particularly wanted to see if it would tune on the 160m band.  More on that later.

The feedpoint of the 9:1 random wire antenna is built into a wire winder to support transport, deployment, and recovery for field use.  The RF functional components include a female BNC connector, a 9:1 unun, and miniature banana jacks for connecting the radiator and counterpoise wires.  There is no wire on the winder, because a corner was broken off during WFD deployment, and a mechanical repair is needed. (Click to enlarge)
The 9:1 unun is mounted near the BNC connector, and is electrically connected to a one miniature banana jack for the radiator and another for the counterpoise.  The unun and wiring are covered with hot melt glue to provide mechanical integrity and protection from the weather.

Radio

The goal of trying the antenna on 160m left me with only one choice for a radio.  I would use the Lab599 TX-500 Discovery, because it is the only transceiver among my field rigs that is capable of operating on the 160m band.  Since a tuner is required, I paired it with an LDG Z-11Pro II, a wide-range autotuner.  I also included a Monitor Sensors Power and SWR Meter in the feed line to help assure that I was legitimately running less than 5 watts to qualify for the QRP power multiplier.

Jonathan takes the Yaesu FT-818ND on an inaugural POTA activation!

Many thanks to Jonathan (KM4CFT) who shares the following guest field report and video:


Chatfield State Park (K-1212)

January 20, 2022

by Jonathan Kayne (KM4CFT)

The honorable Yaesu FT-817/818. You all know it and love it. I had been wanting to get myself one for a while but after just buying myself a shiny new ICOM IC-705, I had been planning on getting myself an 818 in the spring to play around with. December came and I find out that Yaesu was going to discontinue the 818, so I went and bit the bullet and bought one from Ham Radio Outlet.

I had been getting into CW for portable operations lately after wanting to learn CW for a while and my friend Zach Thompson (KM4BLG) had pushed me to learn it. I learned it over the course of two months through an app called “Morse Machine” and listening to Thomas’s YouTube videos while working so as to get used to the exchanges and pick up words. Then I activated and all the rest is history! (If you want to see my 3rd time activating see this video here.)

Why is this important? Because the FT-818ND does not have a narrow 500 Hz filter for CW operation by default, and since I consider myself to be still a newbie I wanted to install a Collins Filter before I take my new 818 into the field. Since these filters are hard to obtain, I went with the build your own route. The method I used has been outlined in this blog and I have made a video of it here.

Now that I had my radio all ready to go with a filter, side rails, and Windcamp Battery, I wanted to get it in the field as soon as possible. Unfortunately due to a snow storm, the temperature in the Denver area was quite cold.

I can handle myself pretty well in the cold if I put on enough layers, but my fingers are another story. I have found that I cannot write properly unless my fingertips are exposed. The solution: do the activation in the car! Continue reading Jonathan takes the Yaesu FT-818ND on an inaugural POTA activation!

Pairing the Elecraft KX2 with a 28.5′ random wire for a rapid POTA activation

On Wednesday, January 11, 2023, I was on my way back to the QTH after a brief trip to Raleigh, NC.

Later in the afternoon, I needed to take my daughters to a class, thus I had a strict deadline to meet. Still, it was a beautiful day so I decided to pop by Tuttle Educational State Forest for a nice walk and possibly an activation if I time allowed.  I’d spent so much time in my car the previous couple of days, I really wanted to stretch my legs.

Tuttle Educational State Forest (K-4861)

As I drove to Tuttle, I made a decision to film a Hike & Talk session–I had a topic on my mind and thought the timing was right to make a recording. You can check out that (previously published) Hike & Talk session here.

After that casual walk, I found that I had a good 45 minute window–no more–to fit in a full activation including set-up/take-down. Very doable!

The radio I had packed away for this road trip was my Elecraft KX2 field kit which included a Tufteln no-transformer random wire antenna (compact equivalent of my 28.5′ speaker wire antenna) and my AX1 portable antenna. I had this particular kit because I’d hoped to do an urban park activation in Raleigh, but simply didn’t have the time to fit it in.

Setting up the KX2 is a swift process.

I chose a picnic table, deployed the Tufteln antenna and was on the air in no time! Continue reading Pairing the Elecraft KX2 with a 28.5′ random wire for a rapid POTA activation

New Penntek TR-35 Field Kit, Canine Welcome Party, & Brilliant 20 Meter POTA Conditions!

There are few things that make me happier than radios and pets.  On Saturday, January 7, 2023, I got copious amounts of both.

On the way back to the QTH, I stopped by Table Rock Fish Hatchery (K-8012) for a nice, leisurely POTA activation.

En route to Table Rock I gave some though to the antenna I might deploy. In the end, I decided I’d once again set up the Chelegance MC-750.

There was no question which radio I’d use: it’d be the brilliant Penntek TR-35 packed-up in its new field kit!

Table Rock Fish Hatchery (K-8012)

Table Rock Fish Hatchery isn’t open on Saturdays, but that really isn’t a problem because the picnic area where I set up shop is open 24/7.

And the best part about Table Rock? The welcoming committee…

These two dogs are so incredibly sweet and always a highlight of activating Table Rock. You may have seen them in my previous field reports and videos. Continue reading New Penntek TR-35 Field Kit, Canine Welcome Party, & Brilliant 20 Meter POTA Conditions!

Field Report :POTA Activation K-0228, Stuart B. McKinney National Wildlife Refuge, Great Meadows Unit

by Conrad (N2YCH)

January 21, 2023

Parks On the Air’s Support Your Parks weekend event for winter 2023 is the third full weekend in January and I found myself without my Jeep. I sold my ten-year-old Jeep Wrangler and my new Jeep wasn’t due to be delivered until the following week, leaving me without my “POTA activation vehicle”. I ended up borrowing my XYL’s MINI Countryman to activate K-0228, but let’s face it, a MINI is not a Jeep. It didn’t have all of my “stuff” in it. I needed to get creative about what to bring along with me that would fit easily in the MINI, yet work well enough to activate the park.

I started with my backpack kit which contains an Elecraft KX3, battery, Signalink and computer (for FT8 and logging).

It includes everything I need to transmit and it’s easy to toss in the car. I just needed to decide on what antenna to use. Since it’s winter here in Connecticut and pretty cold outside, this would be an “in-the-car” activation and without the Jeep, my antenna options were limited. I could have brought my Sotabeams Tac-Mini which could fly my PackTenna EFHW up about 20’. However, anchoring the mast would be a challenge in the cold weather. In the end, I decided to bring my Buddipole tripod and nested mast, which are compact and fit in a small bag which fit right in the passenger seat.
