Photo from morning SOTA activation on Richland Balsam.
Yesterday morning, I took my Elecraft KH1 to the summit of Richland Balsam and performed a SOTA activation using only the KH1’s whip antenna on 20 meters (I ran out of time to hit 17 and 15M).
It was insane fun. Without really intending to, I actually filmed the entire hike to the summit, entire activation, and the hike back to the car. I’m not sure I’ve ever done that before. I plan to post the video by Monday (Nov 6) if at all possible (again, trying to push my KH1 videos to the front of the line for a little while).
Parking Lot Pedestrian Mobile
After the SOTA activation, I drove back to town to pick my daughters up at their acting class. I arrived about 20 minutes before the class ended and thought, “why not pull out the KH1 and see if I can hunt some POTA activators–?”
I opened the trunk of the car, grabbed the KH1 from my SOTA pack and then decided to even film this short, impromptu hunting session.
As you’ll see in the video below, it took no time at all to deploy the KH1, hop on the air and work a couple of stations.
I could have also chased some SOTA activators, some DX, or just looked for a random ragchew with someone calling CQ.
I like hunting/chasing POTA and SOTA activators, though, because the time commitment is manageable. For example, by the time I ended this video, my daughters and one of their friends were already hopping in the car to hit the road. I didn’t have to apologize to anyone for ending a QSO early. 🙂
November is KH1 month
I decided that I’m only going to use the KH1 both in the field and in the shack during the month of November. The only exceptions will be other radios I need to test or if I need to make contacts outside of the 40-15 meter KH1 window.
One of the big reasons for this level of commitment is that I am in the testing group of the KH1. This is how we flesh-out any minor issues that may have gone unnoticed.
Another reason is I do plan to post a comprehensive review of the KH1 eventually and I only feel comfortable doing this after I’ve spent dozens of hours with a radio.
If I’m being honest, another reason is that I absolutely love this anytime, anywhere radio. It’s so insanely portable, I take it with me everywhere. The KH1 and I have been inseparable since last Monday when I took delivery. And, yes, I’m still contemplating what her name will be.
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:
Radio? Check.
Antenna? Check.
ATU? Check.
Paddles? Check.
Battery? Check.
Counterpoise? Check.
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:
Open the KH1 pack
Remove the KH1
Attach the counterpoise and string out on ground
Remove whip from clips and attach to top of KH1
Extend whip
Turn on radio
Find a clear frequency
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’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.
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!

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.
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.
Many thanks to Paul (W0RW) who writes with the following tip:
It is a little cumbersome to log your contacts while walking along the trail. For logging and a Dupe Sheet (used in contests) i use a small NFL Type Cuff Log.
You have seen all the Quarterbacks have their ‘Play List’ on their arm. They are on eBay at:
As a follow-up to my previous post: this chest pack is still a bit of a work in progress but has been tested and works as is. I didn’t want the non-IC-705 owners to feel left out 🙂
The Condor T & T pouch is a frequently reviewed favorite of hikers and hunters – YouTube videos abound. The key feature is the way the pouch opens from a chest plate, or just straps, to form a tray. I expect you could modify other clamshell pouches of other sizes with an adjustable cord to do the same thing. I haven’t seen other pouches built to do this, yet.
The “tray” section contains a number of MOLLE loops as well as some loop material. This makes it easy to fashion your own radio attachment system. I have been using some hook material fastened to the back of KX2 for now, but am working on something that locks in, rather than tempt fate. Continue reading The Elecraft KX2 version of Scott’s chest plate/manpack→
Here’s a MOLLE-related [piece of field kit] you may not have seen yet.
My summer 2022 QRP /PM rig is built around a Condor chest plate – not really a pack although there is a plate carrier compartment that thinner things store in easily enough. And I often have a small accessory pouch in the chest plate.
The key ingredient is the IC-705 adapter plate, made from scrap 0.06 inch thick aluminum scrap.
The four tines that fit the chest plate MOLLE webbing are spaced per the MOOLE/PALS standard of every 1 1/2 inches, but the tines themselves are 3/4 inch wide rather than 1 inch to make them easier to insert in the chest plate.
The plate is attached to the 705 with M4 by 10 socket head screws. I first used a single quick disconnect 1/4-20 photographer’s knob, and it worked, but eventually would loosen enough that the radio would start to swivel.
The orange strap that retains the adapter plate at the top of the chest plate is riveted to the adapter plate with plastic POM rivets. The chest plate is a Condor MCR3, about 26 bucks on eBay.
The radio goes in and out of the chest plate in less than a minute, and the adapter plate can be removed in a minute or two. The radio is very stable and easy to operate.
As a bonus, the loops also hold a Buddistick mast section, then a Versatee with a Buddistick.
With the antenna in front, I can change bands and adjust the whip and coil while standing. The antenna also goes in and out of the chest plate quickly.
I’m finding it’s great fun to listen and operate on the way to and from my operating destination. Definitely the easiest /PM set I’ve had. Every control and jack, and the battery, is easily accessed with the radio attached to the plate.
It’s like the 705 was intended to be used this way!
72, keep up the great work.
Scott ka9p
Absolutely fantastic pedestrian mobile setup, Scott! I love how the custom IC-705 mounting plate makes such a stable surface for the IC-705 to be suspended as you operate. As you say, you also have very easy access to all of the station components. Brilliant!
Thank you for sharing your design notes and photos!
Many thanks to Steve (MW0SAW) who shares the following video of DL1DN making a very enthusiastic contact with VK5MAZ–Germany to Australia–QRP SSB pedestrian mobile:
What an amazing accomplishment! I think I felt as excited as David did in his video. The reception of VK5MAZ was simply phenomenal, too!
uSDR clones
David (DL1DN) mentions at the end of his video that he had been in touch with Manuel (DL2MAN) who is the designer of the incredibly affordable uSDR transceiver project. David had featured a Chinese clone version of the uSDR in some of his previous videos. These days, it’s difficult to know if you’re ordering a clone or the original item because often the clone so closely mimics the original.
As I understand it, the uSDR is completely open source and, at least at time of posting, there is no comprehensive kit version available. However, all of the information needed for gathering parts and building the uSDR are public and free.
Manuel (DL2MAN) made the uSDR project open source with the condition that it cannot be used for commercial purposes (in other words, produced by another party and sold as a product). Of course, it was very quickly cloned by manufacturers in China and is now available on eBay.
David shared a link to Manuel’s recent video speaking about the differences between the two units:
You’ll note that I try to steer clear of clones on QRPer.com. I do this mainly because I like supporting the original developers and designers of radios and kits when possible. I feel like by doing this, I’m supporting the innovators in our community as opposed to taking money away from them.
On that note, I’m in the market for an M0NKA mcHF transceiver!

I decided that I’m only going to use the KH1 both in the field and in the shack during the month of November. The only exceptions will be other radios I need to test or if I need to make contacts outside of the 40-15 meter KH1 window.
