The Elecraft KH1 or KX2? Which one should you buy?

Even before I started taking my Elecraft KH1 to the field and generating reports and activation videos, I started receiving questions from readers and subscribers about how the KH1 might compare with other field-portable radios.

At least 70% of all of these questions asked specifically about the venerable Elecraft KX2.

Making a purchase decision

I’m not surprised so many are trying to make a purchase decision between the KH1 and KX2.

For one thing, the KH1 and KX2 represent some of the smallest, most compact and lightweight shack-in-a-box HF field radios on the market. We’ve a lot of QRP field radios to chose from these days, but few have options for both internal ATUs, internal batteries, and attachable paddles. Very few are as light and compact as either of these two radios.

Another reason for the comparison is that many are in the long queue to purchase a new Elecraft KX2. At time of posting this article, if you place an order for the KX2, you are going to wait a few months for delivery.  The KH1 also has a lead time, but it’s likely shorter than that of the KX2 (check out the Elecraft Shipping Status page for more info).

Comparing models

While the KH1 and KX2 have a lot in common, they’re also quite different in many respects.

We radio ops like to compare features and specifications and Elecraft knew the KX2 and KH1 would be compared frequently, so they created a handy chart:

Click here to download Elecraft’s KX2 v KH1 comparison chart (PDF).

At the end of the day, though, I would argue that one’s enjoyment of a radio has more to do with how well it fits the operating style of the owner.

The KX2 is one of the best portable QRP field radios ever made, in my humble opinion. It’s a little high-performance machine that can handle any mode you care to use between 80-10 meters.

The KH1, on the other hand (pun intended), is designed to be an exceptional handheld radio for pedestrian mobile use and as a super lightweight, low-impact, field portable station. It’s essentially CW-only and operates on 5 bands (40-15 meters).

If you can be honest with yourself about how you plan to use the radio, it’ll help you make this purchase decision.

For example, if you never see yourself operating pedestrian mobile–you’re more of a sit down at a table sort of op–there’s a good argument to go for the KX2. If, however, you’re an avid SOTA/POTA portable activator who is primarily a CW op and you like the idea of a super quick deployment and handheld operating from anytime, anywhere, you should consider the KH1.

Video

To dig into this comparison a little deeper, I decided to make a video where I discuss the differences between the two radios and also speak to different styles of operating and which radio might suit that style best:

I would be curious which radio you prefer and why. Please consider commenting!

SOTA DX with a 20 Meter Delta Loop on beautiful Yonah Mountain!

I’ve taken a wide variety of antennas on SOTA (Summits On The Air) activations, but one wire antenna I’ve always wanted to deploy is a simple vertical delta loop.

This summer, I mentioned to my friend Joshua (N5FY) that I planned to build a delta loop antenna and next thing I know, he built one. I suppose he’d been thinking about adding it to his line of portable wire antennas at Tufteln.

I was planning to build a 20M delta loop fed with twin lead, but Joshua’s choice is better for multi-band operating. His 20M delta loop features a 4:1 transformer so it can be fed with 50 Ohm coax like my RG-316 (which is also easier to pack than twin lead).

You might recall that I used his 20M delta loop antenna at Holmes Educational State Forest (see photo above) in early September. It worked a charm and wasn’t too difficult to deploy (loops are obviously more finicky than a one wire end-fed).

The great thing about this loop is it’s resonant on 20 and 10 meters, and it’s quite easy to tune on 17, 15, and 12 meters with pretty much any ATU.

Fast-forward to Saturday, October 14, 2023 when Joshua and I were participating in the W4G SOTA campout in north Georgia…

Yonah Mountain (W4G/NG-048)

It rained cats and dogs Friday evening into Saturday morning.

Fortunately, most of the rain stopped by the time I surfaced that morning.

Joshua and I ate a quick breakfast, grabbed our SOTA backpacks, then drove to the Yonah Mountain parking area/trailhead.

Last year, we also activated Yonah Mountain as well, but underestimated the hike and our timing. We ended up being a good hour or so late to our SOTA evening potluck. This time, we were keen to spend more time on Yonah Mountain and get back to the campsite in plenty of time to join everyone for dinner (and share exaggerated stories about our SOTA adventures).

Last year, we arrived at the trailhead and it was parked full. This year, even though we arrived in the morning and even though it was incredibly foggy/misty, it was still quite full!

Yonah Mountain is an incredibly popular destination.

Another fun fact about Yonah: it’s not really a beginner’s summit despite the fact it’s so popular with hikers and runners.

It offers up proper elevation change, gnarly trail portions, steep inclines, and about four miles of trail round trip. Although not an incredibly long hike, it’ll give you more of a workout than you might think first blush.

We reached the summit in due time and set up our stations about 30 meters apart.

The whole time, I was also monitoring the partial solar eclipse we were having that day.

I brought along some solar eclipse glasses and ended up sharing them with everyone on the summit. It worried me seeing so many young people staring at the sun with only their sun glasses or even–gasp!–with the naked eye. (I mean, weren’t they paying attention in science class–?) 🙂

At one point in the activation during the actual peak of the partial solar eclipse, I left the radio and did a little more sun-gazing. Continue reading SOTA DX with a 20 Meter Delta Loop on beautiful Yonah Mountain!

Lunch break? Time for a rapid SOTA/POTA activation!

by Vince (VE6LK)

As always there are lots of links within the article. Click one! Click them all! Learn all the things! ? Also, it’s with thanks to the management at QRPer.com who give me this outlet for creative writing.

While on business travel in Northern Alberta recently, I found myself with a slow workday and a few hours owed from lunches not taken that week. A quick plan was hatched and out the door I went after ensuring that all at work was going to be fine without me for 2-3 hours. But before I get to that story…

While travelling to and from this site, I’ve made it a mission to activate as many ATNO [All-Time-New-Ones, ie. never-activated parks] as possible within POTA. I plan these 500km trips with some small side journeys to these parks or natural areas and to break up the otherwise long drive along the foothills of the Canadian Rockies up and down the Highway 22 (aka. Cowboy Trail) corridor. It’s truly a lovely drive and I don’t mind it in the least.

Now back to my late-day lunch break adventure…

With the nearest park to me (VE-3162, Whitecourt Mountain) already activated but only on phone, I figured I’d activate it on CW and do more QSOs than the other activator just for good measure. I can’t believe that a park this close to a townsite had only one activation before I got there to activate it.

If that isn’t enough, it’s also a SOTA entity [VE6/ST-102] with a broad and not-steep slope making the activation zone quite wide. On top of that I can do this two-fer as a drive-up! This worked in my favour as I parked my truck within the activation zone! This SOTA entity had been done a couple of times already so I knew that electrical noise would be my nemesis.

For those of you that may have disremembered, I’m in shape -round- and that shape doesn’t easily climb summits, so a drive-up is totally my kind of summit. But I had to get a move on as there were only two hours left on the Zulu timeclock.  At my hotel room I had more gear, but being nervous nelly that I am at times, I do not leave my KX3 in the room unless there’s a safe. Given that the KX3 gets lonely without companions, I ensure that it always has a battery, antenna and key along for the ride so they keep each other happy as can be 🙂 I had just enough of my portable kit with me to make this happen.

Elecraft KH1 + Speaker Wire = Pileup Madness on Bakers Mountain!

Since the beginning of November, I’ve been pushing my Elecraft KH1 activations to the front of the line so that readers and subscribers who are considering this wee handheld radio might get a chance to see and hear it in action.

So far, I’ve used the KH1 for what it was designed to do: pedestrian mobile/handheld using the built-in whip antenna. I’ve activated a park, a summit, and even did a little parking lot POTA hunting.

I’ve decided that November is KH1 month–this is the only radio I’ll use this month.

I will start blending in some of my field reports from October (there were some really fun ones in there) that feature my other field radios and a variety of antennas starting next week. I’ll still be pushing some of my KH1 field reports to the front during that time as well. Also, I’ll likely post more bonus videos over on Patreon.

Where to activate?

On Monday, November 6, 2023, I had several hours in the afternoon to take the KH1 on another mini radio adventure. I wasn’t sure where I’d perform an activation, though.

This time, I didn’t want to do a pedestrian mobile activation. I wanted to see how the KH1 might play on my kneeboard and how it might pair with my 28.5′ speaker wire antenna. I was curious if its internal ATU would find acceptable matches on all bands.

I packed the KH1, throw line bag, Tufteln Kneeboard, Helinox chair, 2L water bag, camera gear, and speaker wire antenna in my GoRuck pack (FYI: all links and full inventory are below).

This was more gear than I’d need, but all of these items were in my radio box in the trunk/boot of my car.

I had only one errand to run that afternoon: I needed to drop off some of my wife’s illustrated Christmas cards at my friend Hamilton William’s Gallery in downtown Morganton.

After catching up with Hamilton, I had to make a decision about where to go for an activation. I knew this: it was an incredibly beautiful day, so whatever I did, it needed to include a hike!

I considered a few parks but the most convenient spot for a proper hike was Bakers Mountain. It also required the least amount of driving since it was essentially on the way back to Hickory.

Bakers Mountain (W4C/WP-007)

It being an early Monday afternoon, there weren’t many other hikers at Bakers Mountain. In fact, I never ran into any other hikers on the main loop trail.

Bakers Mountain park is (sadly) not a POTA entity. It’s a county park, so does not currently qualify. There was talk once of Bakers Mountain being turned into a state park, but it falls just shy of the amount of acreage needed to qualify.

Bakers Mountain is a one point SOTA summit, but the hike (if you do the full loop trail) is actually pretty strenuous if you take it at a nice clip. I’d consider it a moderate hike overall.

I’ve already activated Bakers Mountain this year, so this activation’s point will not add to my goal of reaching Mountain Goat (1,000 points). That’s okay, though. Unless my family life changes in a way that frees up a lot more time, Mountain Goat is a good 5-6 years in the future at my pace! I’m perfectly fine with that.

I reached the summit and found a spot to set up in the shade. Continue reading Elecraft KH1 + Speaker Wire = Pileup Madness on Bakers Mountain!

My first SOTA activation with the new Elecraft KH1 handheld QRP transceiver!

On Friday, November 3, 2023, I had planned to activate Mount Mitchell–the highest summit in eastern North America. I need to activate Mitchell soon because I’ve yet to activate it for SOTA in 2023 and when winter weather sets in (quite early at that altitude) the park is inaccessible.

Unfortunately, last week, the National Park Service closed an 8 mile portion of the Blue Ridge Parkway due to (no kidding) park visitors feeding and trying to hold bears at the Lane Pinnacle Overlook.

I won’t get on my soapbox about how people are so out of touch with nature that they feel human interaction with bears is a good thing. It breaks my heart because as we natives of WNC say, “a fed bear is a dead bear.” Bears that become comfortable with humans become (at best) a nuisance and (at worst) aggressive.  This is bad for people and it’s bad for our bears who are otherwise shy and avoid humans.

Okay, I said I wouldn’t soapbox about this…

That 8 mile section being closed meant that what would have been a 50 minute drive to the summit of Mitchell turned into a 90 minute drive. Round trip, I simply couldn’t fit that in my day, so I made alternate plans.

Another summit on my list to activate before year’s end was Richland Balsam.

Richland Balsam is actually the highest summit on the Blue Ridge Parkway and is, in fact, at one of my favorite points along the parkway.

That  Friday morning, I dropped my daughters off at their classes and drove an hour or so to the Haywood-Jackson Overlook.

In the valley, as I started my drive to the parkway, past the Cradle of Forestry, it was 30F/-1C. I was concerned that on the summit–nearly 4,000′ higher in elevation–that the temp would be closer to 20F. Fortunately for me, as I gained elevation, the temperature climbed too. We were having inversion that day so the higher altitudes were actually warmer than lower altitudes. This is not uncommon in the fall and was very welcome that particular Friday morning!

Richland Balsam (W4C/WM-003)

Only three weeks earlier, there would have been no free parking spots at the Haywood-Jackson Overlook overlook–it would have been packed.

Fortunately for me, all of the leaf-lookers had gone and I literally had the place to myself. What a luxury!

And the temperature? A balmy 43F/6C.

The hike to Richland Balsam is one of the easiest along the parkway.

At the north side of the parking area, you’ll see a trailhead for the Richland Balsam Nature Loop Trail.

I wish my iPhone camera could haver truly captured how the moon looked in the sky.

The trail isn’t long; I believe the entire loop is just shy of 1.5 miles.

Although I didn’t set out to do this, I ended up making a video of the entire loop trail hike along with the activation (of course, you can skip over those parts in my activation video below).

Sadly, one thing you won’t be able to enjoy in my video? The smell. The air is filled with the fragrance of balsam trees along the entire trail–it’s just amazing!

The summit of Richland Balsam is at 6,410 feet ASL (1,954 meters).

The summit is covered in trees which is brilliant for SOTA activators. Another luxury is that there are two benches within the activation zone. I did pack my Helinox Zero chair as a backup, but didn’t need it.

SOTA with the KH1

Setting up my KH1 for a SOTA activation couldn’t be easier or faster. I show the whole process in my video at a very casual pace. Continue reading My first SOTA activation with the new Elecraft KH1 handheld QRP transceiver!

A Portable Oblong Antenna for 2 Meters


Many thanks to Andrew (VK2ZRK) who writes:

Hello Thomas,

The area I live near Canberra in Australia has many SOTA summits that are easily activated on 2m with a HT. That said a good antenna always helps. The 2m oblong antenna is very popular in these parts. It is easy to make, light to carry and packs small. It is horizontally polarised.

This is the second oblong I have built. I gave my dad VK4FASR my first one and have finally built another. I mostly use the bottom of the band for SSB/morse, the middle for APRS on 145.175 and 145.500 for SOTA. The antenna is cut accordingly.

PARTS LIST
(Sorry about the lack of Freedom units)

    • 8mm fibreglass tube.
    • 8mm ID kite nocks (both from a kite supply).
    • Double walled glue lined heat shrink.
    • 2200mm Antenna wire – DX Commander in this case.
    • 2mm ‘ZingIt’ dyneema.
    • A BNC to banana adapter.

Assembly

I cut the tube so the centre to centre distance between the holes in the kite nocks was 360mm as per Andrew VK1AD’s instructions.

With the wire I started with 2200mm and trimmed until I had the best SWR at 145.000 when I lost my nerve and stopped cutting. [See photos below.]

Everything is held together with the glue lined heat shrink.
The top tube includes a little loop made from the ZingIt to suspend the antenna. Total weight is 102g.

The 2mm ZingIt can hold about 200Kg. I hope the pics make sense

Field Radio Kit Gallery: VE6VID’s KX2 SOTA Kit

Many thanks to Malen (VE6VID)Canada’s first SOTA Double Mountain Goat – who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, read this post.


Hello Thomas,

After being prompted by Vince (VE6LK) I am sending in my humble lightweight HF setup. The core of the setup is an Elecraft KX2 with a few goodies bolted onto it.

My station consists of KX2 with tuner, end plates with lexan cover, external 4s LiPo (1100mah) battery, power cable that is fused and has switched diodes (voltage reducer), an Amazon speaker and earbuds, a modified UV5R microphone (I’m an SSB guy for now), and a homebrew 65 ft EFHW. It’s all carried in a large water bottle case by Condor and weighs in at just under 3lbs. That case also fits an Icom IC-705 or the Elecraft KX3.

I have approximately 300 SOTA activations with this along with various masts. These activations range from easy 10 pointer strolls in Arizona and Manitoba to strenuous (over 1000 metres of gain) 4 pointers in the Alberta Rockies along with summits in VE5, VE7 lands tossed in as well.

By using old Altoids tins for storage for earbuds and the mic, everything fits into the case with the antenna laying on top. I ended up doing some trimming of the kite winder to fit with ease on top of the case.

Here is the basic setup laid out.

The battery will last me for two ten to fifteen minute activations without having to switch the diodes out of line.

When solo activating in VE6 land, I use the Amazon external speaker to make noise to let the local four legged critters know I am there.

After a few years of using a dipole on treed summits, which at times can be troublesome to setup, I built a 49:1 EFHW. When using the EFHW I typically set is up as an inverted V with a mast, invert L with trees. The antenna is a homebrew 49:1 using a non-standard size type 43 toroid, SOTAbeams antenna wire 65 ft long, bulkhead male BNC for connecting directly to the radio.

Trying to go compact, not necessarily light, I ditched the Elecraft mic for something with a small footprint, a mic that started life as an UV5R mic / earbud combo from Amazon . By replacing the cable with a Walmart 3.5mm TRS cable and adjusting the menu on the radio, it works great.

Take care,  Malen Vidler, VE6VID


Vince’s notes: Malen is Canada’s first SOTA Double Mountain Goat. You can check out his YouTube channel here. He is soft-spoken and deeply knowledgeable on SOTA and Amateur Radio. He is one of my go-to people when I don’t understand something in these areas.

Kneeboard SOTA: INSANE DX with my smallest, most compromised antenna!

I walked out of my front door on the morning of Friday, September 29, 2023, knowing I was going to do an activation, but I had no idea where that might be.

I certainly had no idea it would be one of my most memorable activations ever–!

I knew I had a five hour window to play radio somewhere not too far from my daughters’ classes near the Asheville Airport.

I really wanted to do a SOTA (Summits On The Air) activation, but I’d pulled a muscle in my back and was nursing it a bit.  I knew that an invigorating hike on a long, gnarly trail was not really in the books.

After dropping off my daughters, I sat in the parking lot running through the activation options in my head. There were 5 or so parks within an easy drive. I knew a POTA activation probably made the most sense since it wouldn’t require hiking or carrying a heavy pack.

Then again, I really wanted to do a SOTA activation–the weather was so amazing, I didn’t want to miss out on an opportunity to take in a summit.

I decided that if I took a minimal amount of gear and activated an “easy” summit, then maybe I could get away with a little SOTA without hurting my back. I thought this might be the perfect excuse to do a SOTA activation pairing my Elecraft KX2 and AX2 antenna. I had a lightweight chair and my kneeboard, so in theory, I could set up anywhere on the summit with my entire station on my knee.

Next, I only needed to find the right summit and one came to mind almost immediately…

Black Balsam Knob (W4C/CM-005)

The last time I activated Black Balsam was with my buddy, Monty, in 2021. I remembered that it was an easy hike with stunning vistas of Pisgah Forest (K-4510) and the Blue Ridge Parkway (K-3378).

This it the Mountain Ash (Sorbus Americana) with bright red fruit!

I drove 55 minutes to the trailhead and was happy that there weren’t too many cars in the parking area yet that morning. Black Balsam is one of the most popular summits on the Blue Ridge Parkway, so sometimes it can be a challenge to find a parking space…especially with stunning weather like this!

The hike was very pleasant and my GoRuck GR1 backpack was pretty light.

I knew I’d chosen the right summit hike.

The views from the Art Loeb Trail do not disappoint. (Click images to enlarge.)

In fact, if anything, I wish this hike were just a little longer because I enjoyed the scenery so much!

It’s only 3/4 of a mile one way, so it goes by quickly. Still… it’s why I chose this particular summit. I knew it would be gentle on my back (and it was).

Once I reached the summit, I started searching for a spot to set up. There were quite a lot of folks on the summit that morning, so I looked for a site just slightly off of the main trail.

I found an area on a side trail that provided just enough room to set up my folding chair without disturbing the flora.

Bob pairs the KX2 and AX1 for ultralight travel-friendly SOTA in Greece

Many thanks to Bob (K4RLC) for the following guest post:


Field Trip to Greece: September & October 2023

 Bob (K4RLC)

A trip to Greece had been on the bucket list for my YL Alanna K4AAC and me for several years. In fact, we had to postpone the trip twice due to COVID. An opportunity arose to take a unique trip to Greece with the University of North Carolina – Chapel Hill, rather than a more touristy cruise. It’s always good to have fellow Tar Heels around, to share experiences.

This trip involved a few days in Athens, seeing the classic archeologic sites such as the Parthenon and the Acropolis, as well as exploring the packed downtown markets, such as Plaka and Monasteraki Square. Then the group would travel to the South of Greece on the Peloponnesian Peninsula staying in a fishing village called Gytheio, founded in the 5th Century BC, and port to the Spartan warriors.   From there, there would be day trips to historic sites. These included a trip to Areopoli, where the Greek revolution against the Turks started in 1821. Another trip would be to Monemvasia, an island fortress founded in 50 AD.  Other trips would be to Mystras (the last outpost of the Byzantine Empire) and ancient Sparta. On the return trip to Athens for departure, the tour would stop in Ancient Corinth, which had been civilized by the Greeks by the 8th century BCE and where the Apostle Paul preached ethics to this Sin City of ancient Greece.

As I had taken the KX1 and KX2 to various places overseas, I, of course, wanted to operate portable radio  in Greece. Past treasured memories included enjoyment operating with the KX1 on Suomenlinna Island, in the Bay of Finland, and with the KX2 in various Caribbean sites, including St. Lucia in 2019.

One of the first things I did was to consult the SOTA Summits Database for peaks we might be near. In the Peloponnesian (PL) region, there are about 180 sites, many of which had never been activated. Once we got there, we found out why. The peninsula is extremely mountainous, with steep barren peaks up to 4000 feet, rising quickly from the shore. In fact, talking with Cristos, our guide in Areopoli and a local young man, he said that he and his friends would hike about 6 to 8 hours to a summit, then spend the night in a cave before returning home. Obviously, this would not fit in with our somewhat rigid tour schedule.

Olive tree grove & Taygetos Mountains
SOTA map of Peloponnesian Peninsula with Gytheio circled

I was very excited to see that Mt. Mystras, where we would visit, also was a SOTA site (SV/PL-012), as well as a UNESCO World Heritage Centre.

I found it curious that Mystras had not been activated since 2017. I found the name of the last ham who had activated this site, and took a chance of sending him an email at his QRZ address. I was very pleased to get a nice reply from Cristos (a common name in Greece, named after Saint, or “Agios” Christopher), who said that he lived in the north of Greece some distance away and had not been back. I asked him if he had to seek permission to activate there. Cristos said they just didn’t ask anybody, but that I should be “careful of the guards” as I’m not a local.

I took his caution under advisement and reached out to the Greek Radio Union. I received a very nice email from Takis, Vice President of the Greek Radio Union. He advised me that my call sign on the Peloponnesian peninsula would be SV3/K4RLC/P. That is, in Greece the geographic location of operation still matters, while it doesn’t in the United States. And I also should use the designator P, identifying as a portable station. Takis went on to write that radio operation in many the archaeological sites is now “prohibited” by the Greek Ministry of Culture and Antiquities. I filed that away for consideration.

The tour was culturally enriching, taking in the incredibly long and complex history of each ancient site we explored. Just as memorable, we were extremely well fed with local cuisine, including fresh fish caught that day, especially eating by the water in Limeni on the West Coast of the Mani Peninsula. I have to admit we ate spanakopita at least once for 10 consecutive days (it’s even served at breakfast)!

The trip to Mystras also included a trip to ancient Sparta, civilized in the 6th and 5th centuries BC. We were fortunate to have an archaeologist who is currently excavating Sparta as a guide to the fascinating history here. On the trip to Mystras, three miles to the west of Sparta, the bus stopped at the tavern where we would return to eat later that afternoon, for a pre-tour bathroom break. Bathrooms are few and far between in ancient sites, and most of our group could be considered geriatric and needed proximity to a bathroom. Mystras  is a 682 meter sharp  peak over the town (see photo). Continue reading Bob pairs the KX2 and AX1 for ultralight travel-friendly SOTA in Greece
