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! →

Gazebo Portable! A quick hike and speedy QRP POTA activation with the Elecraft KX2 and a 28.5′ random wire

6 Comments


On the morning of Friday, February 3, 2023, I wanted to fit in a quick hike and activation as I made my way back to the QTH.  Tuttle Educational State Forest (K-4861) is my go-to when I want to hike and play radio but don’t have enough time to fit in a proper SOTA activation.

That morning, the park was very quiet–mine was the only car in the parking lot. This being an educational state forest, they tend to get large groups of visitors all at once (typically, bus loads of school kids). In the winter, however, the park is quiet because their restroom facilities and water points are all winterized.

I grabbed my SOTA pack–which contained my Elecraft KX2 field kit, Tufteln/N0RNM folding knee board, and a throw line–then hit the trails!

Although it was a windy day, I headed to the gazebo at Tuttle (one I’ve used for activations in the past) which is on a hill and has a brilliant view of Grandfather Mountain.

Trust me, Grandfather Mountain is out there, my iPhone just can’t easily capture it:

The only issue with the gazebo is that the trees behind it are short and very dense with branches. In the past, I’ve launched a line over the top of the tree, but it’s not easy because then there’s always the possibility your throw weight will land on the roof of the gazebo. You also need a 10oz or heavier throw weight on trees like this, else risk getting your line caught in the tree.

There are a number of pines immediately behind the smaller ornamental trees, but to get to those, I’d need to lay my feedline across a service road the park staff use regularly, so that’s a no-go.

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

11 Comments

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

11 Comments

Many thanks to Conrad (N2YCH) who shares the following field report:

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

12 Comments

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 →

Taking the Xiegu G106 on its maiden POTA activation!

12 Comments

Last year (May, 2022), Xiegu announced a new compact field radio that would be added to their line of transceivers: the Xiegu G106.

As I was capping off my summer in Canada (August, 2022), Radioddity started shipping the G106. Radioddity had me on their list of folks to send a loaner G106 to, but I didn’t have time to even look at the radio I was so busy upon my return, so didn’t immediately request it.

I did watch, however, K8MRD’s initial review and updated review of the G106. It was less than stellar [understatement alert!] but more than relevant to me because Mike shipped his second unit to me on behalf of Radioddity.

I connected that G106 to a dummy load, checked the transmitted signal, and it simply didn’t look very clean. It looked worse than it did when Mike checked it only a couple weeks prior.

I shared my results with Radioddity, told them I didn’t feel comfortable putting it on the air for testing in the field, and they asked to have that unit returned and checked out.

Updated G106

Fast-forward to January 2023 when I was once again contacted by Radioddity to see if I would like to field test an updated G106. I was happy to do so, in fact, because I was curious if the whole G106 experience had improved.

In the spirit of full disclosure: keep in mind that Radioddity is a Xiegu retailer/distributor–they are not the manufacturer nor are they owned by Xiegu. They are a sponsor of QRPer.com, but have no say in what I post nor any sort of editorial input. Indeed, this is always a condition of sponsorship from day one.

To Radioddity’s credit, some of my most critical reviews have been of products they’ve sent me on loan (especially the GSOC).  They take criticism on the chin and keep on moving forward. This is why they are still a sponsor and I like working with them. They understand that I call it like it is and stand by what I publish.

This G106 has been sent to me on loan for a few weeks to review. I plan to take this unit on a number of activations and pair it with a variety of antennas and accessories.

Very early impressions

I will eventually publish a full review of the G106 (likely in The Spectrum Monitor magazine first) once I’ve put in a lot more field and shack hours with the G106. In the activation video, below, I do make a lot of comments about the radio–thinking out-loud–so if you’re considering purchasing the G106, you might at least listen to a few of my initial impressions.

I will say this: for a modern SDR-based transceiver, it’s pretty bare-bones. It lacks a number of features I assumed it might have despite the incredibly affordable $320 US price point:

  • No SWR meter
  • No Power meter
  • No CW or Voice message memories
  • No RF gain control
  • No AGC control
  • No dedicated headphone audio output

But, again, it has more features than many of the bare-bones CW-only QRP transceivers out there, so for the price perhaps expectations should simply be in check–?

Zebulon B. Vance Birthplace (K-6856)

On Tuesday, January 31, 2023, I took the G106 on its maiden POTA activation to K-6856.

The G106 doesn’t have a built-in ATU (which I would never expect at this price point) so I decided to pair it with a resonant antenna. Since it was a very rainy day and the area/ground where I tend to deploy my wire antennas at Vance was squishy and soft, I opted to deploy my Chelegance MC-750 next to the picnic shelter.

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.

Speedy POTA: An impromptu post-hike activation with the Elecraft KX2 and AX1

17 Comments

On Friday, January 27, 2023, I dropped off one of my daughters at the library for a creative writing session.

Hazel was along for the ride, so we decided to hike on the nearby Mountains To Sea Trail (MST) while my daughter was in the meeting.

During the hike, I realized that I should have taken my field radio pack along because it would have been so easy to activate both the MST and Blue Ridge Parkway as a two-fer.

Instead, Hazel and I enjoyed our hike and got back to the car with about 35 minutes or so to do an activation–including set-up, on-air time, and pack-up.  That would leave me just enough time to pick up my daughter at the library before they closed for the day.

Challenge accepted!

Because I had been using the Elecraft KX2 and AX1 recently, I had both packed in my Spec-Ops EDC backpack.  In theory–even filming a video at the same time–I knew I could probably fit in a whole activation with 25 minutes on the air. I only needed 10 contacts, and I’ve never been in a situation where the AX1 couldn’t achieve that goal.

Hazel and I grabbed my bag from the car, I started recording a video, and we made out way to the nearest picnic table at the Blue Ridge Parkway HQ parking lot! Continue reading Speedy POTA: An impromptu post-hike activation with the Elecraft KX2 and AX1 →

KX2/AX1: Second quick activation of the day at Lake James State Park!

2 Comments

As I mentioned in my previous field report, on Saturday, January 21, 2023, I had just enough time to activate two parks in short order on the way back to my QTH

I thought it might be fun to perform both of these activations with the Elecraft KX2 and AX1 combo because they’re so speedy to deploy.

Once again, I wanted to show the whole KX2/AX1 set-up and pack-up process in my activation video.

Lake James State Park (K-2739)

As I pulled into the Lake James Catawba River access, I discovered that there were few other guests there that day. I was expecting more people on a Saturday especially since the weather was so pleasant and South Mountains had been so busy earlier that morning.

Then again, the Catawba River access always has less visitors than the Paddy’s Creek area (which is really the main public access point for Lake James).

I pulled into a parking space, found one of the closest picnic tables, and set up the station in short order.

At South Mountains State Park, an hour earlier, I performed the entire activation on 20 meters. To shake things up a bit, I decided to perform the one at Lake James on 17 meters (note here that the AX1 only works on 20 and 17 meters unless you have the coil which adds 40 meters).

A quick two park KX2/AX1 POTA run starting at South Mountains State Park!

5 Comments

You might have noticed that I’ve been taking the Elecraft AX1 antenna out quite a lot recently. At time of posting, I’ve almost used it for a month’s worth of activations.

In December, I thought it might be fun to only use the AX1 for one 2023 calendar month–say, the month of March–but since I evaluate and review radios and antennas, it’s just not realistic to make that kind of commitment.

That said, I did decide to simply start using the AX1 as my primary field antenna for roughly a 30-ish day period and, so far, that’s working out very nicely. I thought it might give some real-world context and usage for those who still believe I’ve just been lucky the days I use the AX1 in the field. No better way to test that theory than to just do it!

Mini rove!

It’s been a while since I’ve had time to do a proper park rove. I hope to do a five park rove within the next month or so, if I can clear out space in the schedule. I find roves so much fun and a nice change of pace.

On Saturday, January 21, 2023, on the way back to my QTH in the mountains of WNC, I had just enough time to activate two parks in short order. Having just been challenged by a short activation window at the Vance Birthplace (which, turned into a normal length activation due to a schedule change in my favor) I thought it might be fun to once again, show the whole KX2/AX1 set-up and pack-up process in my activation video.

South Mountains State Park (K-2753)

I chose South Mountains State Park as my first stop.

South Mountains has a number of public access points. I decided to drive to the main park entrance and set up at the equestrian picnic area. Choosing the main park entrance added about 15 minutes to my overall driving time; the Clear Creek access would have been quicker, but I’d been there only recently.
