How I worked the #19 most wanted CW DXCC as a pedestrian mobile station

by Leo (DL2COM)

A couple of months ago, I started using the app HamAlert to keep track of interesting DXpeditions and rare call signs just to check if I would be able to copy their signal on my home-made WebSDR at a location outside of the city. This helped me a great deal in understanding propagation and pile-up dynamics as I began to develop a strong interest for expedition-like operating from exotic regions.

One of the stations I had tracked for a while is Monk Iakovos Kutlumusian SV2RSG/A – the only licensed operator in Mount Athos which is currently #19 most wanted CW DXCC according to Clublog. Mount Athos is an autonomous orthodox monk republic under Greek sovereignty and located on a peninsula in the North-East of Greece (locator KN20CG). More info on Mount Athos can be found here (Wikipedia) and a trailer for an upcoming documentary here (Youtube).

The priorities of the community in Mount Athos understandably lie on their theological work. So I think it is a big commitment that Monk Iakovos (QTH: Koutloumousiou Monastery one of 20 monasteries in Mount Athos) is able to make some contacts in his free time outside his monastic duties as he writes on his QRZ page.

Very experienced DXers from Berlin once told me how they worked Mount Athos many moons ago on 80m in the middle of the night only by chance and that it is almost impossible to log this super rare DXCC.

Impossible? Hold my beer.

I had noticed that during May and June 2024 Monk Iakovos was on the air more frequently but each time only working 4-5 stations in a couple of minutes before disappearing again for days. The only two consistencies I found was that he was active on 20m CW and most of the time during local evening hours.

Whoops there he is again – Hamalert notification on the Garmin Instinct 2 watch

I took the photo above a couple of days before to inform a friend that SV2RSG/A was active again (btw the HamAlert notification feature on my watch comes in very handy).

Then on Sunday, June 16th 2024, I was sitting on the couch reading when my watch vibrated and showed his call sign again on RBN at about 20:56 UTC (22:56 local time, 23:56 DX time).

I was in absolutely no position to make a QSO as I live in a very urban neighborhood in central Berlin City and I cannot have antennas at my QTH. Also the location brings along a high degree of man-made QRM and all the tall townhouses act as blockers for any kind of RF. Far from ideal for HF operation which is the reason 100% of me operating is portable or from the car.

In addition, we had just returned from a weekend trip to the countryside and I was enjoying the fact that our kids were sound asleep. So I only took out my phone and checked if I could hear this station again online.

To my surprise, this time it wasn’t the immediate and very intense “red ocean” simplex pile-up that I had witnessed multiple times during the weeks before. Maybe it was due to the fact that a big DX contest was coming to an end or most tired OPs were just off the air already on a late Sunday evening. Who knows? Or maybe it was just plain luck…..

Should I? Or should I not? I knew that I needed to be outside if I wanted to have the slightest chance to work this station. There is also a tiny park about 200 meters from our house which would improve my situation a little due to better “sky access” and takeoff angels towards Greece. But I thought by the time I could be set up the pile-up would already be too big for my QRP signal or the station would already be gone as it was the case each time before.

Still I ran over to our utility room, ripped open my backpack and got the KX-2 pouch out. I took the transceiver, slapped the AX-1 whip on, grabbed a key and dumped the counterpoise wire in my pocket.

Don’t let the shoe situation mess up your TTQ stats (time-to-QRV)

Have you ever wanted to take out the trash and then ran into a “shoe situation” at the front door with your hands full?

With my wife’s sneakers slipped half on I staggered out on the street all while trying to secure the end of the counterpoise to one of the bottom screws on the KX-2’s case and nearly falling down the stairs. Time-to-QRV (TTQ is that an official metric? if not it should be imho) maybe 80-100 seconds….no kidding.

Outside I dialed in 14.004 and immediately heard SV2RSG/A still calling CQ at a relaxed pace and then working a station. The signal in my “street canyon” was weak but a 100% copy.

Elecraft KX-2 and AX-1 whip antenna
Elecraft KX-2 and AX-1 whip antenna got me on the air in no time (I need to set the internal clock again)

I quickly send my call sign only to get a “QRZ?” back. OMG did he really just hear my signal? Apparently my field strength was too weak on his end because he started calling CQ again.

So I sprinted towards the park (dragging along the counterpoise behind me) and I noticed that his signal was coming on stronger and stronger. After about 100 meters I stopped and again called “DL2COM”. This time I heard “DL2?” but then a very loud OP blasting his signal right on top of me.

I repeated my call another two times and couldn’t believe my ears when SV2RSG/A came back with my true full call and a 599 report. With shaking hands I somehow managed to reply R 599 TU and then we exchanged 73s. I simply couldn’t believe what had just happened.

When I walked back to the front door one of my neighbors was standing there looking somewhat irritated. He paused his phone call for a second and asked “ARE WE SAFE?”.

“Oh yes! For now, very safe!” I told him that I had just communicated with a monk in Greece in morse code (“you know the stuff they used on ships back in the day”) and that this story probably needed more context over a beer.

I then noticed that I had pulled the counterpoise wire through a pile of dog droppings with everything happening so quickly. Of course I did! How can this not happen on the streets of Berlin. A sacrifice I was happy to make for this very special contact and btw cleaned easily in under 2 minutes.

Beer bottle and glass

Gear used:

Thanks to QSL manager SV1GRM I did not have to wait long for this card

How did this work? Being on the air so quickly and the fact that 20m was on fire that night certainly helped. But then again is it also the idea to just dare and get out there operating. If you don’t cast a line there won’t be any fish…right?

You never know which exciting DX station might be just around the corner during a special band opening.

While Greece isn’t particularly hard to reach from Germany it was more the overall circumstances (very rare, short and erratic operating times of this station, usage of callsign by pirates, urban QTH, compromised antenna, simplex pile-up with QRP signal) that made this contact highly unlikely but as I now know also totally possible. Blessings to Mt. Athos and their ongoing work for the DX-community! I am very grateful that I got the chance to log them.

p.s. as of the day of publishing this article, Monk Iakovos has not been active since I worked him on June 16th (according to RBN).

Deep Dive: My Mountain Topper MTR-3B Watertight SOTA Field Kit

5 Comments

Last week, in response to a reader’s question here on QRPer.com, I was reminded that I hadn’t yet made a video specifically about my Mountain Topper MTR-3B SOTA field kit.

Yesterday, I made a short video (see below) where I show what I pack in my MTR-3B field kit and why I choose to house it in a Pelican 1060 case.

First, let’s look at a list of the gear, then I’ll talk about what went into my choices, and I’ll link to the video.

Self-Contained Watertight Field Kit:

Optional Gear for SOTA/POTA:

Design Choices

Here’s the philosophy behind my design choices in this kit:

Pelican 1060 Case

I chose to house this field kit in a Pelican 1060 Micro Case even though, at one pound, it weighs more than the typical pouch I also use for small field radios. The Pelican, however, protects the entire radio kit as it’s fully watertight and crush-proof. If I trip while fording a creek or fall and land on my pack, the Mountain Topper will be safe. Yes, there’s a mass/weight cost, but I feel it’s very minimal for the protection it offers.

Counterpoise-less End-Fed Half-Wave

When I build the K6ARK EFHW antenna kit for my MTR-3B, I chose to make it without a counterpoise. Even though the antenna would be more efficient with a dedicated counterpoise and less prone to the effects of body capacitance, I feel like the benefits of this design outweigh the compromises. For one thing, leaving off the counterpoise saves space inside the Pelican case. In addition, by designing the antenna to attach directly to the MTR-3B’s BNC port, there’s no need to include a feedline, thus saving quite a bit of space.

So far, I’ve been very impressed with how forgiving this antenna has been and, most importantly, with how well it has performed.

N6ARA SWR Meter

I include the N6ARA MiniSWR  in my field kit to give me some peace of mind if my antenna deployment is compromised (for example, if the trees on a summit are too small, etc.). Since my MTR-3B version has no built-in SWR metering, I feel this is a meaningful addition tot he kit.

Throw Line and Weight

At least 90% of the summits and parks I activate here in western North Carolina have trees. To me, no field kit is truly sufficient unless I include a throw line and weight. I find that the Marlow KF1050 Excel 2mm Throwline is small, lightweight, and effective—-25 meters is enough to deploy any wire antenna I’d carry on a SOTA activation.

Many SOTA ops use a small sack that they place stones in to act as a throw weight for their line. This is very clever because you don’t have to pack in that extra 8 ounces on the roundtrip hike. Still, I like the convenience of a throw weight that’s designed to glide through tree branches with ease–especially if the tree is dense. If I were to do a multi-day SOTA backpacking trip, I’d probably use an empty throw sack instead of a dedicated weight.

Rechargeable 9 Volt Battery Packs

I love these 9V rechargeable batteries. It’s hard to believe that the MTR-3B can complete 2-3 typically SOTA activations on one charge! Then again, the MTR-3B uses something like 18ma in receive? That’s crazy low current consumption. These batteries are super lightweight and the particular brand I use has never produced any RFI (I’ve read that some others can). What’s best is that I can recharge these easy via a USB-C cable.

The MTR-3B will operate on nine volts, which yields three watts of output power.

Helinox Chair and Kneeboard

Yes, these are luxury items. I know many SOTA ops who are quite happy to sit on the ground and balance their radio on their leg. Perhaps it’s my age, but I don’t like doing this anymore because my legs tend to fall asleep and I lose feeling in them if not careful.

My Helinox Zero chair weighs 1 lbs 2 oz (509 g). I feel like it’s weight and mass well-spent. Since I record activation videos, the chair also gives me a much better position for my camera angle (bonus!).

My Tufteln/N0RNM kneeboard is an essential part of my SOTA kit. I never leave without it. The chair and kneeboard combo gives me the flexibility to set up anywhere, anytime. I love it.

Pedestrian Mobile POTA Hunting: Pairing the KH1 and N6ARA’s Tiny Paddle Plug

8 Comments

On Sunday, March 3, 2024, I had a couple of errands to run in downtown Asheville and also had to pick up my daughter.

I ended up having about 40 minutes to kill and, since I had my Elecraft KH1 field kit packed in my EDC bag, I thought it might be fun to fit in a little radio time.

Since I was downtown, the only viable POTA site to hit would be the Thomas Wolfe Memorial–you might recall my activation there last year–but technically, the park was closed. It is an urban park in the middle of Asheville, and there are no gates to keep people from walking across the grounds, but still, I’d feel better activating with permission from the staff first. (I’m pretty sure they’ll grant that permission, by the way.)

Instead of activating, I decided to do a little POTA hunting.

I parked at the spot where I planned to meet my daughter and grabbed my KH1 field kit.

Upon opening it up, I remembered that I had put N6ARA’s new KH1 TinyPaddle Plug Adapter in the M40 case!

My good friend, Ara (N6ARA), designed a small 3D-printed adapter that allows his TinyPaddle Plug to fit the KH1 securely. He sent me (free of charge) this new key/adapter to evaluate.

The adapter is a super simple design that works with the TinyPaddle Plug (not the TinyPaddle Jack).

I hadn’t used this new adapter in the field yet–I only very briefly tested it at the QTH a couple of days prior.

I mentioned last year, shortly after the KH1 was introduced, that I expected a number of 3rd party paddles to start appearing on the market. Since the interface with the KH1 is a standard 3.5mm plug, it does open the door to 3D-printed designs and experimentation. Admittedly, it’s a small space to fit in a paddle, but it’s doable.

I believe N6ARA was actually the first non-Elecraft paddle I used on my KH1 because his TinyPaddle Plug will fit it natively. That said, the new KH1 adapter makes it a proper secure fit–the way it should be!

Side Note: The OEM Elecraft KH1 paddles (the KHPD1s) are now in Revision 2, and all KH1 owners (who received the original paddles) will get version 2 paddles eventually via Elecraft for free.

The original KH1 paddles have a green circuit board.

I haven’t received my Rev 2 paddles yet, but I know I will before long. It’s my understanding that the Rev 2 paddles have a much better feel, and keying is more accurate.

Still…it’s brilliant that Elecraft used a standard jack so that we hams can design our own paddles if we like.

The TinyPaddle Plug

Ara’s TinyPaddle design is super simple, and while he originally designed the TinyPaddle to be a back-up option, I know a number of hams who use the TinyPaddle as their main field key.

If you’d like to hear more about the TinyPaddle and Ara (N6ARA), I’d encourage you to listen to this recent episode of the Ham Radio Workbench podcast when he was our guest. He’s such a brilliant fellow.

Park Lot Pedestrian Mobile

Again, I can’t stress how cool it is to have a radio that allows you the flexibility to hit the air pretty much anywhere, anytime.

The KH1 is so quick to deploy, low-impact, and low-profile.

It’s as conspicuous as holding a transistor radio with a telescoping whip. So far (it’s still early days, let’s be honest here) no one has seen me with the KH1 and asked me if I’m a spy. I can’t count the number of times I’ve been asked this over the years of POTA activating!

POTA Hunting vs. Activating

Even though both activities–hunting and activating–are a part of the same program, they are very different animals. Continue reading Pedestrian Mobile POTA Hunting: Pairing the KH1 and N6ARA’s Tiny Paddle Plug →

Field Radio Kit Gallery: KO4WDE’s Dual Purpose Xiegu G90 Field Kit

8 Comments

Many thanks to Doug (KO4WDE) 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. 

KO4WDE’s Dual Purpose G90 Field Kit

by Doug (KO4WDE)

I have always been an outdoorsman, and for all of my professional life I have been a teacher.   It wasn’t until 2021 that I became a ham. I started out with my tech, and earned my general a few days later.  I built a modest shack around an IC7300 and a Par Endfedz 80-10M EFHW. When these three facets of my life combined something sparked in me and I immediately did two things, took my radio with me outdoors, and I took it to school. Long story short, we now have a school radio club. (KQ4CWT), and I am a POTA junkie.

The Need:

To go portable, I would take my 7300 with me, powered by a Bioenno 20Ah battery, packed neatly into a hard case, with the battery and Wolf River Coil SB1000 stuffed in the front pockets of a massive brown deployment style bag.  My “go kit” was more like a “Hire a mover kit” and weighed a ton.  This worked well, but I really wanted something different.  I needed a portable field radio kit that would be small enough for me to use when hiking and camping, but also serve as a valid and friendly introductory platform for middle and high school students exploring ham radio.

I needed a radio that would provide some of the luxury of the IC7300, including the panadapter waterfall for seeing signals, as well as SSB, and digital mode capability.  The kids, like me, really like FT8.

The Solution:

I settled on the Xiegu G90 radio.  It was much smaller and lighter in weight, had less power consumption, and had many of the features that I thought would still hook kids’ interests, as well as serve me well in the field.  An internal and capable tuner is much appreciated as well. I love the G90, and my students love the G90.

The Build:

To build this kit, I started out with the basic components: the radio, the battery, and the antenna.  To power the radio I use a Bioenno 9ah battery.  It is a bit bigger than what I need but this comes in handy for FT8 activations and the demanding duty cycle penalty that entails, and gives me some slack for device charging. The Wolf River Coil antenna was replaced by an antenna that my club built as a project.   It is a 3D printed chassis and winder for the antennas components and wire designed by (IU10PK) and listed online as “tactical end fed antenna winder” on thingiverse. In addition to these basic components I added an FT8 kit consisting of a DigiRig Mobile, needed cabling and a Evolve III notebook pc.

After reading all of the gallery builds here, I decided to choose a medium sized sling bag to fit the rest of the loadout. Again, I was looking for something to pull double duty for POTA and student work.  My huge original “Hire a mover kit” taught me that I had a tendency to carry way too much. I wasn’t aiming for “Spartan Simple” but I wanted to cut as much as I could. I made a list of my radio critical components, and my support components and shopped accordingly.  I intentionally chose a bag slightly smaller than what I thought I would need to force myself to trim the fat.  I settled on the “Large Rover” sling pack by Red Rock Outdoors.  I chose gray because it would look more at home in my classroom than FDE or OD green, but the color has really grown on me.

The Bag: Red Rock Outdoors Large Rover

(Meme dog talisman adds 5db to all antennas- a wonderful handmade gift from a student!)

The main compartment:

 The main compartment of the bag carries the G90 (with the semi-attached and very bulky fan unit), battery and a Tactical Tailor shemagh I use as a table cloth or ground cover for my bum.  I use the rolled shemagh as a protective layer between the battery and radio.  The battery sits inside the main compartment nicely as well.  Inside the main compartment, there are two sleeves, the rear is unused but the front sleeve houses my coax cable.  The zippered “flap pouch in the top of the main compartment stores my hand mic.  I use little 3D printed protective covers for the mic connectors.

(Little 3D printed protectors for connectors)

The other compartment(s):

The front of the bag has a medium sized pouch with several elastic loops and sleeves.  I use this pouch for my EFHW antenna and my “K4SWL” style bare bones 25M arborist throwline.  There is a small zippered sleeve on the outside that carries an additional 100 feet of 3mm Paracord divided into two sections.

(The front compartment is quite roomy)

At the top of the bag, there is a small zippered pouch that houses my Digirig Mobile and assorted cabling for the G90.  It also carries my charger for the Bioenno battery, and a tiny Anderson Powerpole to USB-C PD charging adapter made by Tufteln that I use to top off the Evolve III’s battery.

The rear of the bag has a very nice sleeve for a device.  The evolve III is a perfect fit.

The Wrap-up:

Although I am new to ham radio and field operations I feel like this little budget kit works exceptionally well for its dual intended purpose.  It’s capable for use in the classroom (or school grounds) as a teaching tool, but also small enough to not murder me on the trail.

The Kit Components:

            Red Rock Outdoors “Large Rover” sling bag

  1. G90 radio with “H2” stand (note: this is an affiliate link that also offers a discount to QRPer.com readers)
  2. 9Ah Bioenno LiFePO4 battery and 2 amp charger

Field Radio Kit Gallery: WN1C’s Elecraft KX3 Camera Bag Activation Kit 

3 Comments

Many thanks to Thomas (WN1C) 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. 

KX3 and Speaker Wire Camera Bag Activation Kit 

by Thomas (WN1C)

For the QRPer’s Field Radio Kit Gallery, this is my KX3 and speaker wire in a camera bag activation kit.

This kit is the continuation of the equipment I used for my Maine ATNO expedition and other activities on that return to my parents almost a year ago. Primarily, it’s a change in bags and an improvement of the audio connection options for more sustained activations. Writing up this kit for the gallery also will probably be an incentive for further change. With how loosely packed it is, there’s space for options! You can see this kit in action on my recent trail activation.

The bag packed and ready for an expedition, even if just a little ways away.

The outside is the discontinued Peak Design Everyday Messenger 15″ v1. I picked this up lightly used on my local craigslist with an eye for expanding the kit contents capabilities. In that endeavor, it has been successful, but concentrating on this configuration to start:

Open the top to reveal the gear packed between dividers!

There’s a certain pattern (that I might not keep following in future re-packings), but the arrangement internally is:

  • Outer pouches: coax, radials, headlamp as necessary
  • Lid flap padded pouch: infrequently used adapters and short cables
  • Left division: antenna(s), throw line and weight, headset, coax, banana cables
  • Mid-left division: logging pouch with paddles and notebook
  • Mid-right division: KX3 with cover and heatsink
  • Right division: power cables, hand microphone, lithium-ion battery banks, LiFePO4 battery pack
  • Flopping around on top: TH-350 HT
  • Front zipper pouch: additional notebooks, earbud headphones, pen, coax, ARRL VE badge

Of course, not all of this gets used at the same time. Different LiFePO4 options with Anderson Powerpole connectors can be substituted. For quick and lighter operating (or when wearing more hats), the headset can be left behind. Anyway, to the details!

Full contents spread out much wider than I usually have space for! Featuring the wooden floor I rarely operate over because apartment living.

So, what is all of this?

Bags

  • Peak Design Everyday Messenger 15″ v1 (discontinued, acquired second hand) with an additional bright red divider stolen from one of my Crumpler camera bags
  • Case Logic accessories pouch from who knows where (underneath the notebook)
  • One of WesSpur’s low cost throw line bags (don’t get it, it’s smelly plastic and falls apart, as shown in the picture)

Radios

  • Star of the show: Elecraft KX3 in the “KX3 Pack” configuration (KX3, KXAT3, KXBC3, MH3) with Side KX KX3 Combo panels and cover, plus an aftermarket heatsink
  • TYT TH-350 tri-band HT (144-222-430 MHz) with bundled SRH-17 tri-band whip

Getting RF Out

  • 2x 28′ (ish) speaker wire on BNC-F to binding posts/banana connector, in use for a while, though now beefed up with a bit of heat shrink and crimped spade lugs
  • 4x 17′ speaker wire shorted together on dual banana plug (radials)
  • 6′ RG-58 BNC-M to BNC-M with a random split ferrite on it from who knows where
  • 2x Pomona banana test leads for occasions of connecting more things together
  • 60′ Marlow Excel Throw Line 2mm (a K4SWL recommendation)
  • WesSpur 10 oz Throw Weight
  • Assorted S-Clip Plastic Carabiners for the speaker wire, throw line, and whatever else needs clipping together
  • CablesOnline 25′ RG-316 with BNC for spare feedline
  • 2 foot BNC RG-316 jumper
  • Adapters: BNC F-F coupler, BNC-M to dual Banana-F/Binding Post, Dual Banana-M to BNC-F, BNC tee, BNC to center Banana-F/Binding Post; all provide options of hacking some options together

Getting Signals In and Out

  • Koss SB-45 Communication Headset (cheaper relative of the popular Yamaha headset; it shows, mostly in the cable quality)
  • Bamatech Bamakey TP-III Rot (an excellent set of dual paddles that can also serve PTT duty) stored in an Altoids Peppermint tin
  • Cable Matters Retractable 3.5mm Audio Cable
  • Hosa YMM-261 Stereo Breakout to allow use of the SB-45 electret mic with another switch wired to a 3.5mm plug for PTT on the KX3 mic port rather than just VOX
  • Custom microswitch to 3.5mm PTT (not very good at its job) using this snap switch
  • Elecraft MH3 hand mic from the kit configuration
  • Old Apple earbuds, headphones only (TRS)

Power

  • Bioenno BLF-12045W 12V / 4.5Ah LiFePO4 pack (can be substituted with the 3Ah pack I also have)
  • Anderson PowerPole to barrel plug for KX3 power
  • Old (sometimes RF noisy) USB Type-A power banks, one with a built-in flashlight (souped up with a much nicer white LED)
  • Misc USB cables, A to Micro-B and C for charging from batteries

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

4 Comments

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.

Seal the Deal: Exploring the Best Watertight Cases for the Elecraft KH1

7 Comments

Well before I actually had a KH1 in hand, I noted the dimensions of the radio from the preliminary spec sheet and started exploring the world of compact, watertight cases.

Why a watertight case?

This Pelican 1060 case houses a complete Mountain Topper MTR-3B field kit including a throw line and throw weight.

I like to have a watertight case option for pretty much any QRP radio I take on SOTA (Summits On The Air) activations.

It’s reassuring to know that if I stumble and fall on my pack, the case will prevent me from crushing the radio. In addition, a good case keeps my radio dry if I get caught in heavy rains or (even more likely) slip on a rock and fall in a river/creek. In fact, many of these watertight cases will float with the KH1 inside so if it goes overboard while kayak mobile, it’ll be easy to retrieve. (For the record: I don’t want to test this theory.)

With one exception, all of the cases I explore here cost somewhere between $25-$40. I consider this cheap insurance for a $500-1100 radio.

My requirements

I searched a few manufacturer’s websites and tried to find interior dimensions that would accommodate the KH1 and all protrusions: 1.4”H x 2.4”W x 5.6”L (3.5×6.1x14cm).

I primarily searched two watertight case manufactures: Pelican and Nanuk. I trust products from both of these companies and both offer compact watertight cases. There are more manufacturers out there, but but both of these companies offer quality products. Pelican cases are even made here in the USA. Many Nanuk models are made in Canada, but not their Nano series included here.

In the end, I was searching for two case sizes:

  1. A compact case to only hold the KH1 “Edgewood” package: the KH1 with paddle attached, Cover/Logging Tray, Whip Antenna, and 13′ Counterpoise. There also needed to be enough room for a pair of earphones.
  2. A slightly larger case that would accommodate the KH1 “Edgewood” package along with earphones, a throw line, throw weight (or rock sack), and a simple random wire antenna.

The idea with the second, slightly larger, case is that it would give me the option to use a wire antenna during an activation and would be fully self-contained (meaning, everything needed for the activation included).

The contenders

I took a total of eight cases to a local park and spread them out on a picnic table for this test. This made the process of comparing the cases quite easy. I actually made a video of this whole process–you’ll find the video further below in this post.

Here are the cases I tested in the order you find them in the video (any Amazon links here are affiliate and support QRPer.com):

Hint: many of these cases are available in multiple colors–prices can vary greatly based on the color. A red case might cost as must as 30% less than a black case, for example.  Always check the pricing of color options, but make sure you don’t accidentally select a different size case in the process (this is easy to do).

Again, you’ll see a lot of detail in the video below, but let’s look at each of these cases with my notes: Continue reading Seal the Deal: Exploring the Best Watertight Cases for the Elecraft KH1 →

FX-4CR Field Activation Kit

by Evan (K2EJT)

I have a lot of QRP field radios (more than I need and then some).  Some of them are one trick ponies, and some of them can do several things very well. One radio, however, does everything well, and ticks every box for me.  It’s tiny, well built, runs all modes very well, has 20w output, a color waterfall, and doesn’t break the bank.

That radio is the FX-4CR from BG2FX.  Now, before I sing the praises of this little radio, I need you to know that it wasn’t always great.  In fact, when I first got it it was pretty painful to use.  I’m primarily a CW operator, so if a radio is lousy for CW, it doesn’t get used.

This radio was pretty atrocious on CW when I first got it.  Keying was strange.  It would miss dits and dahs.  It had all sorts of popping and artifacts when you sent.  It was fine on receive……but sending was pretty much unusable.  I got it, used it for one activation in May, and then put it away in my gear closet, disgusted at how bad it was for CW.

Fast forward to the August 2023 firmware update, and Yu fixed all of the weird CW bugs, and now I can wholeheartedly sing the praises of this radio.

This kit lives in a Pelican case I’ve had forever.  I forget which model it is (it’s so old the label fell off years ago), but it fits the kit nicely.

Inside the case you’ll find everything you need for a field activation.  Notice I didn’t say a CW activation……ANY activation.

CW?  Absolutely. In fact, with the latest firmware this radio is an absolute pleasure to send on.

SSB?  Heck yeah.  The audio from this radio is very good. The external hand mic is tiny but well built, and the radio even has an internal mic which is quite good as well.

Digital?  Ah….digital.  Now THAT’S what sets this radio apart from pretty much any other QRP field radio out there aside from the IC705.  This thing has a built in sound card, so digital is a breeze.  Wait….you forgot your USB cable you say?  Not a problem, because this thing has Bluetooth digital as well, and it works flawlessly. You’ll notice a cell phone in the pictures.  I run FT8 on that via Bluetooth using an Android application called FT8CN.  All you need is the rig and your phone, and you’re in business.

Aside from the rig itself and the Pelican case, this kit contains the following:

  • Bioenno 3ah battery
  • The hand mic
  • Power cable
  • cwmorse.us key
  • Retractable 3.5mm cable
  • Rite in the Rain notepad for logging
  • Pentel mechanical pencil
  • Weaver 8oz throw weight and 65’ of hi viz reflective cordage
  • 15’ of RG316 coax
  • Spark Plug Antennas EFHW and a homebrew wire for the antenna
  • The user manual
  • My phone for FT8

(Gear links below)

There are also a set of flip down laptop legs on the radio from Amazon to get the viewing angle correct.

Now, this radio isn’t perfect (no radio is).  There are a few things to keep in mind.

First, it’s small, but it’s heavy (530g or almost 19oz).  Second, because it’s a 20w radio and it’s as small as it is, it can get hot…..very hot if you’re running digital.

Third, the firmware update process is a little nerve wracking.  Aside from that, it’s a pretty sweet little radio for $550.  It would be nice if it had an internal battery and a tuner, but I can live without those considering how much functionality is packed into this little rig.

Out of every field radio I own (and as I said, I own a ton), this one is probably the most capable.  It’s amazing for CW (finally), SSB, and digital.  It’s tiny.  It’s 20w.  It isn’t crazy expensive.  If I’m doing anything other than just CW in the field, this is one of the radios I grab most often.  Is it the best radio I own?  No.  Is it awesome for what it is?  Absolutely!

Introducing the new Elecraft KH1 handheld-portable CW QRP transceiver

74 Comments
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!

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.

Hi Tom,

I thought I would share the two go kits I have. I tend to customize my equipment and supplies before I go on a POTA or SOTA outing but I keep these for the rare occasion when I want to grab a radio real quick. [The first on is my] QRPlabs go kit:

The kit is for my QRP Labs QMX/20 meter QCX mini. It contains everything I need to operate 20 meters CW.

The case is a regular Lowepro case that I got with my KX2 when I purchased it from another ham. I did not realize it came with it so I accidentally ordered an extra from Elecraft which I now use with the KX2 kit [featured in a future Field Kit Gallery post].

The kit uses many components from K6ARK, including the 20 meter EFHW antenna and the retractable paddle.

The battery is a TalentCell from Amazon. I use it because it supplies 12v instead of 13.8v. One of the downsides of the QMX is that it cannot handle 13.8v, so I have to stick with 12.

I keep a cheap pair of earbuds with me just in case but I try to bring a nicer pair of headphones whenever possible.

Hopefully this information is useful to you and your readers!
