My First POTA Activation with the New Elecraft KH1 Handheld QRP Transceiver!

Yesterday, I posted some initial notes about the Elecraft KH1 and mentioned that I hoped to perform a POTA activation later in the day.

I’m pleased to report that I was able to fit in that activation!

I’m pushing this report and video to the front of the line because so many readers are eager to see how the KH1 performs during a field activation. Instead of focusing on the park, in this field report we’ll be taking a closer look at the KH1 and my initial impressions after performing a pedestrian mobile POTA activation with it.

Packing the KH1

I had a very hectic schedule yesterday and was on the road in/around Asheville from 8:00AM to 2:00PM before an opportunity opened to fit in an activation.

After a quick trip back to the QTH for lunch, I packed the Elecraft KH1 field kit in my EDC pack (a travel laptop bag).

Herein lies my first impression of the KH1: even though I knew I had packed the entire kit, I felt like I must have been leaving something behind.

Sounds funny, but even though I pride myself on making fully self-contained field radio kits, I felt like there must have be something else I needed. The KH1 field kit just seemed too small, too lightweight, and too compact to have included everything I needed for an activation.

Intellectually, I knew that it included everything needed, but I still did a mental inventory:

  1. Radio? Check.
  2. Antenna? Check.
  3. ATU? Check.
  4. Paddles? Check.
  5. Battery? Check.
  6. Counterpoise? Check.
  7. Log book and pencil? Check.

Hard to believe, but it was all there.

Trust me: the first time you take your KH1 to the field, I bet you’ll feel the same way I did.

Blue Ridge Parkway (K-3378)

Because I was so short on time, I decided to activate the Blue Ridge Parkway which is the most convenient POTA entity when I travel into Asheville from Swannanoa.

It was cold and blustery afternoon the afternoon of November 1, 2023. At my QTH, I checked the temperature and it was about 34F. I knew it would be a bit warmer in town which is a good 1,000 feet lower in elevation, but I still grabbed my gloves on the way out the door. Glad I did!

As I mention in the activation video below, I wasn’t exactly on my “A Game.” I had received a couple of vaccines the previous day and my body was a bit achy as if I was starting to get the flu. But, of course, I wasn’t. Still… I didn’t feel 100%.

I arrived on site and set up couldn’t have been easier:

  1. Open the KH1 pack
  2. Remove the KH1
  3. Attach the counterpoise and string out on ground
  4. Remove whip from clips and attach to top of KH1
  5. Extend whip
  6. Turn on radio
  7. Find a clear frequency
  8. Hit the ATU button for a 1:1 match!

We’re talking a 30 second process even for someone who moves slowly.

Important notes about my KH1

Keep in mind the following notes that are relevant at time of posting this field report (November 2, 2023):

  • I am waiting on a firmware update to add:
    • CW Message Memories
    • CW Decoding
    • Internal Logging
  • I purchased the full “Edgewood” package but I don’t yet have my logging tray/cover yet. Elecraft plans to ship this within the next few days.
  • My KH1 is a very early serial number because I’m in the volunteer testing group.

The KH1 Speaker

The KH1 internal speaker is located on the bottom of the radio between the AF Gain and Encoder knobs.

I consider the Elecraft KH1 speaker to be a “bonus” feature. The speaker is small (1.1 x 0.65”) and limited in fidelity.

I had planned to connect my Zoom digital recorder to the KH1 and record audio directly from the headphone port during this activation. Continue reading My First POTA Activation with the New Elecraft KH1 Handheld QRP Transceiver!

Update: Some Elecraft KH1 Initial Notes

I’ve had the Elecraft KH1 in my hands now for a little over 24 hours. I had hoped to squeeze in a POTA activation yesterday, but the stars did not align. I had way too many dad responsibilities on Halloween.

I hope to correct that today with a POTA activation, if I can squeeze it into a hectic afternoon. It’ll be a cold, blustery one for sure!

Yesterday, I did fit in a couple of opportunistic contacts with the KH1 along with some morning on-the-air time in the home office while working on projects.

Since I’ve gotten so many questions about the KH1 since Monday, I thought I’d share a few random answers and notes here.

Does the KH1 work on a desktop?

Quite a few of you have written in to ask how well the KH1 works on a desktop. Some have mentioned that they like the size of the KH1, but don’t see themselves doing the pedestrian portable thing.

The answer is, the KH1 works really well as a small desktop transceiver.

In fact, yesterday morning, if I made contact with you, it was with the KH1 on my desktop while I was plugging away on spreadsheets in the office.

Elecraft designers cleverly positioned the AF Gain and Encoder knobs so that they’re accessible when the radio is lying flat on its back.

As you can see in the photo above, the key plug is positioned between the two knobs, but there’s enough separation there that you don’t feel your key cable is in the way while making adjustments. Of course, the rest of the controls are on the top, so they’re very accessible.

To be clear, I prefer using my KX2 or KX3 on a desktop (they were designed for this), but I feel the KH1 works quite well.

In fact, for the average 30-60 minute park activation where I’m connected to a wire antenna? I see myself using the KH1 on a tabletop.  I’ll operate pedestrian portable when doing SOTA and fitting in those little opportunistic and impromptu radio sessions.

Ergonomics/Features

The ergonomics of the KH1 are excellent. It was designed to fit in the palm of your hand, and it does this perfectly. Continue reading Update: Some Elecraft KH1 Initial Notes

Amazing POTA Fun: Pairing the Elecraft KX1 and AX1…but first, a little lunch!

I was speaking with my buddy Joshua (N5FY) in mid September. He’d recently acquired an Elecraft KX1 and the topic came up about pairing the KX1 with the AX1 antenna. I realized that in all of my experimenting with the AX1, I’d never paired those two. What!?!

Time to fix that!

On Thursday, September 28, 2023, I had a nice midday window to play radio. After dropping my daughters off at their classes, I stopped by the French Broad Food Co-op and grabbed a container of their chicken noodle soup from the refrigerator section.

I then made my way up the Blue Ridge Parkway (K-3378) to the Craggy Gardens Picnic Area at Bearpin Gap–one of my favorite spots on the BRP.

Despite stunning weather and the beginnings of fall foliage, the parking lot was pretty empty. After all, it was a Thursday and a good week or two before leaf-lookers descend upon western North Carolina.

I pretty much had the picnic area to myself (there was one other person there). I picked a picnic table at the top of the hill under the trees.

Mahlzeit!

When my wife and I lived and worked in Munich, the salutation I learned before any other was “Mahlzeit!” At Siemens, I remember walking through the hallways and people I’d never met before exclaimed “Mahlzeit!” as I passed by.

I quickly learned that Mahlzeit essentially meant “Lunch Time!” and I still say it today to my family when I’m about to make or grab some lunch. Funny how these things stick with you.

Now where was I–? Oh yes…

First thing I did at Craggy was set up my stove to start heating the soup. I show this in my activation video below.

If interested, here are the components of my stove kit:

Quick continuity check!

Next, it dawned on me that I would need to attach the AX1 counterpoise to the KX1. I didn’t bring one of my copper clamps to attach to the outside of the AX1’s BNC connector, so I needed to find another grounding point on the KX1.

I then remembered that the KX1 has two thumb screws on the bottom of the radio. Knowing Elecraft, I assumed that these screws could be used as an attachment point for a counterpoise, but I wanted to confirm that the screw itself had a direct connection to ground.

Fortunately, I keep a small multimeter in my supplemental gear bag in my car. It’s an inexpensive Allosun Pocket Multimeter. I use it for things like this: testing.

I set the multimeter to read continuity and then placed one probe on the outside of the KX1’s female BNC and the other on one of the thumb screws. Sure enough, there was a direct connection to ground. I didn’t need to worry about the KX1 chassis paint insulating the connection to ground because the thumb screw had a direct connection. Perfect!

Thomas,

Like you, I have a number of QRP radios with differing deployments. Some go in the trunk of the car, others go in my shirt pocket.

Here is a fully featured QCX-Mini station in a Tupperware container.

While I believe QRP operation and non resonant antennas should be mutually exclusive, I have the Elecraft T1 as an option. Also when I burn a hole in the sky going QRO, the TalentCell gives me full 5 watts. If needed they both fit in the antenna sack. The 9 volt rechargeable is for normal use.

Earbuds, key and EFHW and I am QRV.

Coffee, QRP, & Question: Is any field kit more portable and versatile that Elecraft’s KX2/AX1 combo?


Lately, I’ve been kitting out another fully self-contained field radio kit that would be small enough to fit in my EDC (everyday carry) laptop bag–something super compact.

I’ve been getting some great ideas from those of you who have added your kits to the Field Radio Kit Gallery.

[By the way, if you’ve submitted your kit to the gallery and haven’t seen it yet, note that I’m posting these in the order received and there are many in the pipeline!]

I’ll likely build my EDC field kit around the Elecraft KX1 or the Mountain Topper MTR-3B, then pair it with a good wire antenna.

My EDC laptop bag: the Tom Bihn Stowaway

But this process got me thinking: if money was no object, and I wanted the most compact and versatile multi-band field kit, what radio and antenna system would I choose?

My answer? A kit built around the Elecraft KX2 and AX1 antenna.

In my experience, the KX2 AX1 combo is hard to beat. It’s compact, effective, low-profile, and you can set it up pretty much anywhere.

Let’s explore my reasoning here keeping in mind–in my world–this is a very deep rabbit hole to go down. I’ll do my best–no promises–to keep this as concise as possible:

Compact, Low-Profile, Self-Supporting, and Simple

Here are all of the components of my typical KX2 AX1 field kit:

This is all that is needed for a field activation.

And if you’re an SSB operator? You don’t really need a microphone because one is built into the KX2 (that said, I’d suggest you build a compact mic if you plan to do a lot of SSB operating).

If I wanted to make this kit even a bit more versatile? I’d add a kneeboard to the list. This gives one the ability to operate without a picnic table.

I recently published a video showing how the KX1 and AX1 can fit on a kneeboard.

Portable and Versatile

What makes this field kit so portable is that the KX2 is one of the most compact general coverage HF transceivers on the market.

It’s certainly the most compact (at time of posting) when you realize that two important components–the battery and ATU–are internal options.

The AX1 antenna is also incredibly compact–it comes apart in such a way that no one component is longer than about 6 inches. What you see in the photo above is the entire radio and antenna system.

Yes: A Compromise

Sure–and let’s get this out of the way right up-front–the AX1 is a compromised antenna, and being a massive fan of simple wire antennas myself, I know a properly deployed wire in a tree is going to provide better gain each and every time.

Also, people who live in more remote parts of the world–say, Hawaii, the Yukon, or Perth, Australia–where the amateur radio density is sparse within their propagation footprint, the AX1 will not be as productive as it is for me here in the eastern half of North America.

Introducing the new Elecraft KH1 handheld-portable CW QRP transceiver

WG0AT holding the Elecraft KH1

From Elecraft:  something BIG, in an incredibly small package…!

Just this morning, Elecraft introduced the new Elecraft KH1.

In brief, the KH1 is a five-band (40, 30, 20, 17, and 15 meter) handheld QRP CW transceiver with options for an internal battery, internal ATU, whip antenna, and fold-out logging pad.

Exciting!  And if you’d like to get the scoop on this new handheld radio–– along with photos––we’ve got it here.

Q: What is the Elecraft KH1?

WG0AT with the KH1 making contacts pedestrian mobile.

A:  The Elecraft KH1 is a compact, five-band CW QRP transceiver designed for both handheld and tabletop operation. Indeed, the “H” in the model number signifies “Handheld.”

To be clear, although it is quite small, the KH1 isn’t just a tiny radio:  it’s ergonomically purpose-designed, to be a pedestrian-mobile CW station.  It’s lightweight, easy to hold and use, and will fit both right and left-handed operators. With the optional “Edgewood Package,” it also includes a fold-out logging pad.

Q: How much does the Elecraft KH1 weigh?

A: With all options (ATU, Antenna, Battery, and logging pad) the KH1 weighs in at a featherweight 13 oz.

Q: What features does the Elecraft KH1 offer?

A:  Here’s a feature list from the Elecraft brochure:

KH1 features:

  • 40-15 meter ham bands
  • 6-22 MHz for shortwave broadcast band listening
  • CW mode; 5 watts, all bands
  • ATU includes whip & high-Q inductor for 20/17/15 m
  • 2.5 AH Li-Ion battery & internal charger
  • CW decode & 32K TX log
  • Scan/mini-pan feature
  • RTC [Real-Time Clock]
  • Full remote control
  • Speaker
  • RIT, XIT, & VFO lock
  • Light gray case stays cool even in bright sunlight
  • Three CW message memories with chain and repeat functions

Like nothing else on the market…

The KH1 design is all Elecraft and built on several years worth of design iterations. It is, no doubt, fueled by Wayne’s passion for handheld portable HF.

Again, the KH1 focuses on ergonomics that would make handheld operation not only easy, but enjoyable.

The two main multi-function controls (the AF Gain and Encoder), for example, are located on the bottom of the radio. This gives the operator easy and ergonomic access to the controls while the radio is in-hand.

The four buttons on the top of the radio default to the most useful functions one would need while operating portable. Using them to dig deeper into the menu levels, however, is also intuitive and well thought-through.

While the KH1 menus and features are naturally not as deep as those of the KX2 and KX3, it’s impressively well-equipped for a radio this size. At the end of the day, it’s a much more simple field radio––by design––than its KX2 and KX3 predecessors. If anything, it’s more akin to the venerable KX1!

(Source: Elecraft)

The KH1’s paddles (KHPD1) are located at the bottom of the radio––they flip down for transport, and up during use, so your fingers are well away from the AF and Encoder knobs.

The KH1 has an optional internal ATU that is not as wide-range as that of the KX3, KX2, or T1, but is much better than that of the KX1. I understand that it’ll match most of what you throw at it.

Wayne told me that one of the most complicated parts of the KH1 design was the fold-out logging pad. He wanted the logging pad to be functional for one-handed operation. The indents around the loose-leaf logging sheets allow you to pull out a completed sheet and slip it behind the others in the stack.

The logging sheets are available as a PDF download; simply print and cut. No doubt, the format would be easy to modify.

Whipped!

This is the part I love: the KH1 is designed to operate with a telescoping whip antenna.

Basically, you unclip the whip from the side of the radio (assuming you have the ATU/whip option) and screw it on the top of the top. The ATU will match the whip antenna––there’s a mechanical slide switch that selects 15/17 m or 20 m high-Q inductance for whip––or an external antenna on the BNC port.

If you’ve been reading my field reports and watching my videos, you know I’m a huge fan of the Elecraft AX1 antenna. The KH1 basically has the option of a built-in AX1 antenna…Just take my money!

Speed…and stealth

If the counterpoise is already attached and wrapped around the body of the KH1, you will be able to deploy the station and be on the air in about 20 seconds.

As many of you know, I’ve always said that the secret power of the AX1 and AX2 antennas is speed of deployment. The KH1 allows for an even speedier deployment.

This will be most especially appreciated when activating summits in the winter where exposure to the elements from simply setting up the antenna and station will often make your hands go numb.

Also, the KH1 is so low-impact and low-profile, you’ll be able to activate parks that might otherwise be off limits to an HF field installation. I know of one urban park that, with permission, I’ll definitely use the KH1 to activate; it has no park benches and no trees, just a strip of grass around a historic building in the middle of a city. Perfect for the KH1!

KH1 versus KX2?

The KH1 and KX2 are very different animals. Elecraft actually produced this comparison chart to help potential customers make a purchase decision.

KX2 & KH1 Comparison Chart (PDF)

My advice? If you have a KX2 on order, don’t cancel it.

The KH1 is not a KX2 replacement. The KX2 is a much more capable radio. The KH1, however, is a radio focused on ultra lightweight, low-profile, pedestrian-portable, CW HF field operation.

A KH1 review?

Yes, it’s coming! I will purchase and review the KH1 “Edgewood” package. My unit should ship next week, so look for updates and photos, and I will push those field reports and videos to the front of the line.

To be completely transparent:  I have been in a volunteer group of testers for the KH1. Other than this, the only real affiliation I have with Elecraft––besides knowing Wayne, Eric, and some of their staff––is being a long-time customer. I own, or have owned, every radio they’ve ever made, save the K3 and K4 lines. And it’s Elecraft that makes my favorite field radios.

Check out US7IGN’s “PFR-5” QRP Radio!

My good friend, Wlod (US7IGN), sent me the following message recently and has kindly allowed me to share it here on QRPer:

Hi Thomas,

I was going to write to you too. I saw your posts on QRPer.com about QRP field kits and decided to share my collection of QRP radios, which I keep now. One of them is my homemade one.

I called it PFR-5 because it has 5 bands, unlike original PFR-3, which was taken as a basis.

The rest are my friends’ radios that I’m temporarily storing. Tulip/Tulipan SDR from SP3OSJ, ELECRAFT KX3, and copy of Mountain Topper and original PFR-3.

I did not compare them, because this needs to be done outside the city where there is no noise and you can evaluate their RX performance, which I cannot do now for obvious reason.

Have a good day!


73 de US7IGN!

Thant’s brilliant, Wlod! I think you may have the only PFR-5 in the world! Ha ha! I love how you marked it as the “Ukrainian Edition” and gave it that brilliant image on the front face.

Thanks for sharing with us, OM! I dream of the day you can take these radios to the field and give them a proper comparison.

W2AEW Field Radio Kit

I’ve only been active with POTA for a little over a year, but have put together a kit that gives me lots of options for antenna deployments.

The main kit is in an old camera bag that I picked up at a hamfest for $5:

One of the outside side pockets houses a small tripod and some little ground stakes for securing support ropes, etc.

The other outside side pocket houses a small digital recorder and a cellular hot spot:

The front outside pocket houses some rubber coated twist ties that I use for securing a portable lightweight pole, as well as a few POTA brochures, QSL cards and eyeball cards:

The pouch on the inside of the lid contains a 25’ length of coax, a few extra pens and other accessories:

The main chamber houses the KX2 Shack a Box bag, a Maxpedition accessory bag, the AX1 antenna kit and my iPad:

The KX2 bag is the main bit of the kit.  Sometimes, this is the only thing I carry with me (and will often put the AX1 kit inside also):

The rightmost pouch contains the 40m EFHW antenna, which is one of my two workhorses for my activations.

The middle section holds the logging pad, writing utensils, spare wire bits for antenna and counterpoise use, lightweight clips, etc.

The main section of the bag holds the KX2 which includes the internal battery and tuner. Continue reading Field Radio Kit Gallery: W2AEW’s Comprehensive Elecraft KX2 Field Kit
