POTA Field Report: Gazebo QRV & Gusty Winds with the Elecraft KX1 and K6ARK EFHW

One of the things I love about our state and national parks is that no matter how often I visit, there’s almost always something new to discover.

This is especially the case as the seasons change from winter to spring.

On March 20, 2022, I carved out enough time in my afternoon to fit in a quick activation of Tuttle Educational State Forest. My main goal, in truth, was fitting in a nice hike–the weather was beautiful, although it was rather gusty.

I needed a little “radio therapy” that day as I had been spending time in the hospital with my mom who had a nasty case of pneumonia. This was a few weeks ago and she’s feeling much better now, thankfully, but those hospital weeks in March were pretty stressful for all of us.

Field activations are such an effective way for me to get in a little exercise, a little radio time, and clear my mind; again, proper “radio therapy.”

Tuttle Educational State Forest (K-4861)

For this trip, I packed the Elecraft KX1 field kit which included my K6ARK EFHW antenna since that was the last pairing I’d used int he field (click here to read that report). I did, however, transfer the KX1 to my new Pelican 1060 waterproof case.

I actually have a solid yellow Pelican 1060 case for the KX1, but after reading about Leo’s QCX-mini field kit built in a clear-topped Peli 1060, I realized how much I missed having a clear lid on the 1060. I checked Amazon and discovered that their blue one was on sale, so I grabbed one. This was a total impulse purchase, by the way.

And for the record: I’m accused of being a radio enabler on a daily basis, but in my defence I promise the enabling works both ways! I’ve bought so many things based on reader recommendations. 🙂 Continue reading POTA Field Report: Gazebo QRV & Gusty Winds with the Elecraft KX1 and K6ARK EFHW

Antenna Challenge #2: K6ARK End-Fed Half-Wave paired with the Elecraft KX1

I mentioned in a previous post that my personal Activation Challenge for 2022 was “to build a new antenna each month and deploy it at least once that month during a field activation.”

In January, I built a doublet with a military fixture/winder.

For February, I decided to purchase and build a counterpoise-less end-fed half-wave kit from from Adam (K6ARK).  This kit is available on Amazon.com for a mere $19.95 (affiliate link).

The build itself is pretty straight-forward and not terribly complicated. With that said, you do need a fine soldering iron tip and a little dexterity to manipulate these super tiny components. Adam includes instructions for building an EFHW with a counterpoise, without a counterpoise, or a random wire antenna. The coil can be configured as a a 49:1 Unun, 9:1 Unun, or 1:1 Balun.

If you choose the EFHW route you will need to solder one surface-mount capacitor on the board. If you’ve never worked with surface mount components before, take your time and use a good magnifying glass.

Blue Ridge Parkway (K-3378 NC)

On Monday, February 21, 2022, on my way back from town, I hopped on the Blue Ridge Parkway and drove to one of my favorite roadside spots on a grassy hill surrounded by trees.

Since I configured the K6ARK kit as a counterpoise-less EFHW, I wasn’t entirely sure how stable the SWR would be in the field. For this reason, I was a wee bit nervous pairing it with my MTR-3B since that little radio lacks an SWR meter and really needs a good match.

I decided, instead, to pair the K6ARK antenna with my Elecraft KX1 which has a built-in ATU that can both monitor the SWR and find an impedance match if needed. Of course, I turned off the internal ATU for the activation, but if I needed it, I knew I could engage and use it.

Leo’s complete QCX-mini field kit and ZM-4 manual tuner kit

Many thanks to Leo (DL2COM) who recently reached out after watching my livestream with Josh at HRCC on the topic of QRP/CW portable. 

Leo shared some photos of a complete radio kit he built around the QCX-mini along with a ZM-4 ATU kit he also recently built. Leo has kindly agreed to share these on QRPer.com.

Leo notes:

Attached is a photo of my ultra light kit.

It consists of a QCX-Mini 20m version (self-built), K6ARK EFHW, Palm Radio Pico Paddle, Eremit 2Ah LiFePo battery, headphones and a few cables.

I usually also carry a small arborist kit and if there is still room also the 6m mast from Sotabeams, depending on what I think will work best.

I chose a hard case and went for the Peli 1060 Micro. It has room for everything I need and it could easily hold a bit of RG316 coax in addition (even more if I chose to shorten the 30m arborist line).

The main benefit for me is that I really don’t have to worry at all about what’s inside – compared to a soft pouch. So I can just shove it into my backpack or glove box and forget about it since this configuration is a lot more rugged and water proof – while being slightly heavier.

Steve is QRV in the Swiss Alps

Steve (MW0SAW) and I were recently exchanging emails and he has kindly allowed me to share a few photos and details of the QRP field kit he has taken on holiday:

I’m currently in Switzerland (ski holiday)–I did bring the Venus SW-3B. I was very surprised to get 2 USA stations last weekend with 4-5 watts in the ARRL CW contest.

Only a couple of Europeans today. But it’s all fun and I did have a lovely morning ski so can’t complain lol.

My gear:

Wow, Steve! I would love to be in Switzerland right about now. I’ve got a bucket list item to journey there someday (in summer months) and activate at least 10 summits. Having lived in Grenoble, the Alps always feel a bit like home.

I love how compact your setup is and obviously the K6ARK EFHW is doing the trick if you’re making contacts State side with QRP and during a contest competing with the big guns!

Hmmm…I’m now thinking I might grab a second Maxpedition Fatty Pouch. I just checked and Maxpedition still has the “buy one, get one free” deal on their website.  The link above goes to Amazon (hence the affiliate link which my site auto-converts) because pricing is typically best there, but I believe you get an even better deal at present going directly to the source; especially if one could use two pouches!

Thanks again, Steve, for sharing your field kit photos and notes!
