A Review of the LnR Precision Mountain Topper MTR-4B V2
by Thomas (K4SWL)
I confess, there is something that I’ve come to believe is almost a rite of passage in the SOTA (Summits On The Air) community. And, no, I’m not talking about activating an All Time New One (ATNO) summit, or completing a particularly challenging activation on a snow-capped peak.
I’m talking about owning one of the iterations of the amazing “Mountain Topper” pocket-sized QRP CW transceivers designed by Steve Weber (KD1JV).
This little radio first caught my attention at a Four Days In May (FDIM) QRP conference over a decade ago: a ham friend in the SOTA community proudly showed me a very early version of the Mountain Topper that he built from a kit. The first thing that struck me was how impossibly small and extraordinarily lightweight it was. But when he showed me the 9-volt battery he used to power it––a power supply not only small, but convenient––I was mesmerized.
Over the years, the Mountain Topper has evolved. There have been many models, ranging from two bands to five. To my knowledge, they’re no longer offered in kit form, but LnR Precision manufactures and tests these in North Carolina, and they’re better than ever in terms of features and performance.
At present, the MTR-4B V2––the second version of the four-band Mountain Topper––is the only model in production, and if you’re hoping to acquire one, due to supply chain issues (at time of publishing) there’s a rather long wait time. They retail new for $350 US, and frankly, the used ones I’ve seen posted in ham radio classifieds ads have been equal to, or even over, the listed price for a new rig. Obviously, demand for these radios is much higher than supply.
So, how could it be that this minuscule QRP radio performs well enough to produce some serious DX from a remote summit…so well, in fact, that people are willing to wait in line for one?
Magic or method?
As any CW operator will tell you, the magic is in the mode. CW is such an efficacious mode that it cuts through the ether like a knife, even when conditions are less than favorable.
Obviously, pint-size radios like the Mountain Topper are QRP––low power––so designing them around such a simple mode is a very smart choice. CW transceivers are much less complex than a similar SSB transceiver, thus have less components, less mass, and are in general more affordable (when compared to those with similar receiver performance).
My comprehensive MTR-4B field kit (the MTR-4B is in the mesh pocket).
In addition, the Mountain Topper is designed with the field activator in mind: specifically, SOTA activators, but of course, POTA (Parks On The Air), WWFF (World Wide Flora and Fauna), IOTA (Islands On The Air), or any other popular “-OTA” field activity. As a field activator in one of these programs, you are the DX. This means chasers and hunters are actively seeking your signal, and thus you are not competing with blowtorch stations to punch through a pileup.
I can also assure you that standing on a tall summit also gives you a brilliant starting point for your QRP signal. Some of the best DX I’ve ever worked has been from a summit.
So, for the average CW SOTA activator, QRP is preferred because QRO simply isn’t necessary––indeed, in my opinion it’s a bit of an overkill. At least that’s been my experience now with my few hundred SOTA, POTA, NPOTA, SOTA, and even one Lighthouse On The Air activations.
Naturally, as with any camping trip or extended travel, I’d put a lot of thought into choosing the portable transceiver and field kit to take along.
The great thing about camping at a state park is that I can “activate” that park via the “Parks On The Air” (POTA) or “Worldwide Flora and Fauna” (WWFF) programs pretty much anytime: early morning, late afternoon, or even in a late shift well into the night. Or, of course, all of the above. Since my activation site is also where I’m eating and sleeping, my radio usually gets heavy use.
Before leaving on that April camping trip, I knew what radio I wanted to operate the bulk of the time: my Yaesu FT-817ND. For a lot of reasons which I’ll delve into later, I think the FT-817ND (or its latest iteration, the FT-818ND) is an amazing QRP field radio.
Despite unstable propagation and a little campground QRM that moved in over the weekend––no doubt from a neighboring RV, chock full of noisy switching power supplies––I found the FT-817ND activation to be a most enjoyable experience. I posted a few field reports and activation videos from my New River activations on QRPer.com.
The thing is, each time I publish a field report using the FT-817ND, I receive a string of questions from subscribers and readers. Questions such as…
Should I buy a new FT-818 or a used FT-817?
Why do you like the FT-817ND so much?
What’s the difference between the 817 and 818?
How does the FT-817/818 compare with _____ radio?
Most queries, however, are a version of this comment from reader David:
“We have such a wide array of QRP rigs available to us these days, I’m curious what brings you back to the Yaesu for activations? It’s bigger than our more modern radios, with no ATU and more current draw. I’m just wondering if there is something that you find it does particularly well, or if it’s just ‘because I like to use it,’ which to me is an entirely valid reason, too! My 897 served me well, as does my 891; I’ve had Yaesu handhelds forever, so I’m certainly a fan. I don’t own an 817/8 but they have a devoted following so I just wanted to get your perspective on it.”
Or as another subscriber distilled the question:
“Why choose a legacy design like the 817/818 when newer QRP transceivers have better overall field specs and features?”
Of course, these types of questions are simple enough when it comes to asking, but when it comes to answering, much more complex.
Of course, as I said in my recent TSM article about choosing a field radio, one’s love of a particular radio is by definition quite subjective, and this certainly applies to my response…we all have our own personal preferences. But behind these preferences are objective facts, such as product’s unique features, specifications, and form factor; let’s take a look at these.
“Look at this, Tom! Only the stuff I need and nothing more,” cheerfully noted my good friend and Elmer, Mike (K8RAT). It was Field Day two decades ago, and Mike was gazing at his TEN-TEC Scout. I glanced over, and agreed. “So simple and so effective,” Mike added.
I’ve never forgotten Mike’s sage words. That Scout (Model 555) was about as simple as a then-modern HF transceiver could be: it had a total of three knobs––one for AF gain and IF bandwidth, one for RIT and Mic gain, and an encoder. It also had three mechanical switches on the front: one for power, one for TUNE and NB, and one for CW speed and RIT. It also had an analog SWR/power meter. The Scout used plug-in band modules for each HF band and featured a large segmented bright green LED frequency display that was characteristic of so many TEN-TEC rigs of the day.
And Mike was right. For those of us who appreciate radios with a simple, uncluttered, and an almost utilitarian interface, the Scout was, in vintage parlance, “the bee’s knees.” And that the Scout also performed beautifully was just icing on that cake.
When the Scout first appeared in 1994, embedded menu options and spectrum displays were not yet commonplace among amateur transceivers. Embedded menu items can open the door to near granular level control of your radio’s functionality and features. Then again, if those embedded menus aren’t well thought out, it can lead to awkward operation practices in the field, during a contest, or even during casual operation.
As a radio reviewer, I spend a great deal of time sorting out embedded menu functionality and design. Perhaps it’s for this reason that I so enjoyed reviewing a radio that bucks this trend and reminds me of a time that was simpler, not to mention, easier.
All of his transceiver kits are available at his website WA3RNC.com.
I was first drawn to the TR-35 after reading the opening paragraph of the product description:
“Compact but powerful 4-band, 5-watt CW transceiver kit that uses no tiny push buttons, and without those seemingly endless and hard-to-remember back menus. There is a knob or a switch for every function!”
Sold!
I considered buying and building the TR-35 kit, but I wanted my eventual review––this one!––to focus on the radio’s functionality and performance. So a factory-assembled and tested unit was right for this purpose, just so that any performance issues wouldn’t be a result of any shortcomings in my kit building skills.
A review of the Xiegu X6100 portable SDR transceiver
by Thomas (K4SWL)
Do you remember when band scopes and spectrum displays started appearing on radios? It was a pretty phenomenal innovation. Being able to “see” what was in your neighborhood on a particular radio band was incredibly useful, especially to operators who like to hunt stations, and to DXers who wanted to follow the reply pattern of DX stations running split. Spectrum displays, among other things, gave operators an overall “big picture” of band activity, and it was truly insightful.
Additionally, the advent of SDR (software-defined radio) architecture made not only spectrum displays but also time-based waterfall displays accessible in radios of all price ranges.
From the perspective of both a ham radio operator and a shortwave radio listener, I can tell you that once you become accustomed to the benefits of a spectrum display, when you don’t have one, you feel like you’re cruising the band wearing blinders: it’s just that essential.
As a result, many hams and SWLs have come to rely on these features. No doubt customer demand has pushed manufacturers to include spectrum displays on almost all new SDR-based transceivers––even portable transceivers!
Enter the X6100
In November 2021, China-based radio manufacturer, Xiegu, started shipping their latest SDR transceiver: the Xiegu X6100.
Xiegu has become quite a household name among HF field operators. I’ve reviewed both the Xiegu G90 and the Xiegu X5105. The common theme is their affordability, portability, superb built-in ATUs, and impressive feature set. Admittedly, high-end performance––in terms of receiver as well as audio performance––is not their strong suit, but in the field you don’t necessarily need contest-grade performance. I’ve found that both the G90 and X5105 are quite effective and adept in the field and at home. Many a new ham operator has turned to Xiegu products to begin their foray into the world of HF.
Judging by appearance alone, you can tell that Xiegu was targeting the same operators who might consider the Icom IC-705. Cosmetically it’s strikingly similar in terms of knob, screen, and button placement on the front panel.
The X6100 also has Bluetooth and WiFi connectivity, like the IC-705: a first for the sub-$1,000 portable radio market. But unlike the IC-705, this functionality was not in place with the first production run of the X6100. It’s being slowly implemented via X6100 firmware updates.
But in my view, that’s where the similarities with the IC-705 stop. Based on the announced X6100 specifications, I could tell well before the X6100’s release that it would lack many of the features that make the IC-705 such a hit; features like a touch screen, D-star mode, VHF/UHF multimode, built-in GPS, built-in D-Star, built-in repeater directories that can auto-load the repeaters closest to the operator, advanced filter shaping, and so much more.
This month, we’ll take a deeper dive into the types of radio kit you might choose to assemble based upon your activity goals. And finally, we’ll look at my “golden rules” of field kits, which I hope you’ll find useful.
Types of field radio kits
I configure and outfit my radio kits based on the environment in which I plan to deploy and operate, and which determines in no small way just what I need to pack besides the basics.
I roughly divide my field kit types as follows…
The Field Day or “Picnic Table” Kit
This is probably the most popular type of field kit in the world of amateur radio. Picnic table kits are designed with portability in mind, but not designed with distance hiking in mind. This is a very popular type of kit for Field Day or park activations through POTA or WWFF.
These kits are typically packed in a backpack, a Pelican-type utility case, or a self-contained and field-ready box.
My picnic table kit is packed in a large Red Oxx C-Ruck rucksack. If I haven’t already made it clear, I’m a self-professed pack geek and I love this Red Oxx Pack because it has large zippered pockets on the outside, a rain flap with storage on top, and one large compartment on the inside.
Most of my on-air time is in the field. While I enjoy operating from the shack, I’ve discovered I especially enjoy operating in the great outdoors.
Besides being a fan of hiking, camping, and the great outdoors generally, I also am particularly fond of radio field gear. I like portable transceivers, portable antennas, battery packs, and all of the accessories that make field operation efficient and enjoyable.
I appreciate the emergency communications skills I’ve developed in the field, too. Should the need (or opportunity) arise, I now keep a complete field kit packed and ready to go at all times, and can even deploy all of it within just ten minutes. In my early days of ham radio operation, I might have easily spent thirty minutes setting the antenna, alone…especially on Field Day, with folks watching me struggle to untangle wires and cables, followed by the undoubtedly entertaining attempts I made to put a line into a tree to deploy the antenna. But after deploying a variety of antennas hundreds of times now, I find that––while I’m still not perfect––I finally have a bit of skill and the process of tossing up a line is becoming much swifter and smoother.
Confessions of a pack geek
The Red Oxx C-Ruck loaded and ready for the field!
If I’m being honest with myself, I admit: I also simply get a thrill out of kitting out my field packs, as well as organizing and tweaking them over time. Yes, (don’t judge me!) I actually like packing up my field gear.
I think my passion for organizing and packing gear goes back to a former career when I lived in the UK, Germany, and France, and was required to travel throughout Europe frequently. Originally inspired by travel guru Rick Steves, I’ve always appreciated the footloose feeling of having all of my travel gear in one lightweight pack. I don’t like checking in luggage, but love the freedom of grabbing my backpack and skipping the baggage claim carousels. And I also like knowing that, even though my gear is compact, it contains everything I need.
I’ve become something of a “less-is-more” traveller. Two years ago, for example, I traveled for one week using what Frontier Airlines classifies as a “personal carry-on.” My Tom Bihn Stowaway pack, which only measures 14.0″ (w) x 9.4″ (h) x 8.1″ (d), carried everything I needed for a conference, including my own presentation gear.
My Tom Bihn Stowaway personal carry on convertible pack with everything I needed for a one week trip including a conference.
Packing for that trip was great fun as it really challenged me to decide what was essential and what was not. My iPad doubled a computing and presentation device, for example, but I also packed a small flashlight and a mini first aid kit, which I felt were important. Of course, I also carried a small portable Shortwave/AM/FM radio and my Yaesu VX-3R handheld…also vital, as I can’t leave home without radios!
Getting started with a field kit
Putting together a field radio kit is so similar to packing for travel: you must first do an assessment of what you need, starting with the basics––then organize it, pack it, and test it.
In my world, this is a very deep topic. We’re going to break down this topic into two parts.
This article, Part 1, we’ll dive in:
first, going over the obvious components of a basic field radio kit;
second, discussing the benefits of going low-power (QRP) if that appeals
In Part 2, we will:
look at variations of kits based on activity, and finally
review what I consider the “golden rules” of a good field radio kit
The basics of a field radio kit
First, let’s go over the basics of your field kit, considering that that these primary components will dictate your bag, pack, or case size.
A transceiver
The lab599 Discovery TX-500
Since I’m a bit radio obsessed, I have a number of QRP transceivers I like to take to the field. But if you have selected one transceiver you plan to dedicate to field work, or simply have only one transceiver, period, you can build a kit around it (and see my note below about “modular” kits). If budget allows, you might consider buying a radio specifically for field use, so it can always be packed and ready to go.
There are a number of transceivers on the market that are designed with field use in mind. Some are compact, power-stingy CW-only QRP transceivers that might only operate on three ham radio bands, while others are 100-watt general coverage transceivers that even have built-in antenna tuners––there’s a wide range of options.
Look for field-friendly, built-in options like:
CW and voice-memory keying;
SWR and power meter readings;
a battery voltage indicator;
low current consumption;
the ability to lower power to at least one watt;
an internal battery option; and
an internal antenna tuner option
And the more such options are already built into your field rig, obviously, the less separate accessories you’ll need to pack and keep track of in the field, which is a good thing.
The Elecraft KX2 has a built-in ATU, battery pack, and even attachable CW paddles!
Some of my favorite field-ready general-coverage transceivers currently in production are:
The Elecraft KX2 A full-featured, inclusive, and compact 80-10 meter transceiver that’s truly a “Swiss-army knife” of field operation (see November 2016 TSM review)
The Elecraft KX3 Benchmark performance, wide array of features, and compact design
The lab599 Discovery TX-500 Military-grade engineering, weatherproof, spectrum display, and benchmark current consumption for a general-coverage radio (see October 2020 TSM review)
Mission RGO One Top-notch performance, 50-watts out, and excellent audio (see November 2020 TSM review)
The Yaesu FT-817/818 Rugged chassis, 160-6 meters, VHF and UHF multi-mode, both BNC and PL-259 antenna inputs
The Xiegu X5105 Affordable, 160-6 meters, 5 watts output, built-in ATU, and built in rechargeable batttey
The Xiegu G90 Affordable, relatively compact rig with built-in ATU, color screen with spectrum/watefall, good audio, and 20 watts of output power (see August 2020 TSM review)
The Icom IC-705 Benchmark performance, a multitude of features, exchangeable battery packs, 160-6 meters, VHF and UHF multi-mode, D-Star, GPS, WiFi, Bluetooth (see February 2021 TSM review)
The Yaesu FT-891: Affordable relatively compact radio with detachable faceplate, 100 watts output, and excellent audio (see November 2017 TSM review)
An important side note for field contests: if you plan to use a field transceiver in an event like the ARRL Field Day and/or another popular radio contest, make sure you choose a transceiver that can handle tightly spaced signals in an RF-dense environment. This is not the time to pull out a lower-end radio with poor receiver specifications. Use Rob Sherwood’s receiver test data table as a guide.
An antenna––and a means to deploy/support it
The CHA LEFS sloper
This particular topic, alone, might warrant a three-part series of articles. So, to keep the scope of this article realistic, let’s just say that you should build or buy an antenna that can comfortably handle the wattage you’re pushing into itin all the modes that you operate, considering that some 100-watt SSB-rated antennas might melt or arc if you run 100 watts CW or FT8.
I would suggest you consider having at least one resonant antenna, like an end-fed half-wave (EFHW) that might cover 40 and 20 meters without the need of an antenna tuner to match the antenna impedance to your rig.
Some of my favorite portable antenna systems?
I’m a big fan of Chameleon Antennafor their ease of deployment and benchmark build quality. Their prices range from $145 for the Emcomm III random wire, to $550 for their MPAS 2.0 vertical antenna system. These prices are near the top of the market, but Chameleon antennas are all machined and produced in the US and the quality is second to none. These are antennas you might well pass along to the next generation, meaning, really heirloom-worthy kit!
The PackTenna 9:1 UNUN
PackTennas, likewise, are pricey for such a compact product, but they are also beautifully engineered, lightweight, and designed for heavy field use. PackTenna produces an EFHW, 9:1 UNUN random wire, and linked dipole models. They’re some of the most compact field antennas on the market that can still handle as much as 100 watts of power output.
My Wolf River Coils “TIA” vertical antenna
Wolf River Coils verticals are affordable, compact, and resonant––thus an ATU isn’t needed. It will take some time to learn how to adjust the coil during frequency changes, but they work amazingly well. I have the WRC Take It Along (TIA). Their antennas are designed to handle 100 watts SSB, 50 watts CW, or 20 watts digital.
The EFT Trail-Friendly
Vibroplexsells a number of compact field portable antennas and is the manufacturer of Par End Fedz offerings. I’m very fond of the EFT Trail-Friendly and the EFT-MTR.
The MFJ-1984LP EFHW packs a lot of performance for the price
MFJ Enterprisesalso has a few portable antennas in their catalog, and it’s very difficult to beat the price and performance of their antenna gear. I have their $50 EFHW antenna (the MFJ-1982LP) and love it.
The Elecraft AX1 attaches directly to the BNC port on the KX3 and KX2.
I’ve also had tremendous fun with the uber-compact Elecraft AX1 antenna. Unquestionably, it’s the most compact and quickest-to-deploy antenna I own. It’s designed to pair with the Elecraft KX2 and KX3 using the optional internal antenna tuner.
There are a number of other antenna manufacturers who cater to portable operators. For example––although I’ve not yet had the opportunity of testing their antennas––SOTAbeams is highly regarded among SOTA enthusiasts.
Short on cash? No worries; you can build your own! In fact, until 2016, I had never purchased a field antenna; I built all my own. EFHW antennas and random-wire antennas are no more than a carefully-wound coil, a female antenna connector, an enclosure or mounting plate, and some wire. Some of the most active field operators I know homebrew all of their antennas. It’s easy, affordable, and fun!
Make sure you choose a battery that is sized appropriately for your transceiver power output. I will say that I’m a huge fan of LiFePo4 rechargeable batteries for their voltage range, lightweight design, and longevity. Being primarily a QRPer, I typically use 3 to 4.5 amp hour batteries as they’ll carry me through as many as three or four activations without needing to be recharged. For longer field deployments, or when I’m powering my 100W KXPA100 amplifier, I’ll use my 15 aH Bioenno LiFePo4 pack.
I use my 15Ah Bioenno LiFePo4 pack for QRO transceivers
It should go without saying that you need to pack these, but I have gone to the field with operators who forgot their key or mic and asked if I had a spare.
Keys are fairly universal, but keep in mind legacy transceivers often want a ¼” plug while newer rigs typically accept an ⅛” plug. Microphones, however, vary in port type and pin configuration based on the manufacturer and model. You could damage your mic or rig if you plug in a multi-pin mic that was designed for a different transceiver. Most mics that use a ⅛” plug are universal. Still, check before you plug it in if using an after-market or non-OEM mic.
Of course, choose a key, microphone, or boom headset that’s compact and rugged so that’ll be easy to pack and will stand the test of time.
I also always pack a set of inexpensive in-ear earphones. These can dramatically help with weak-signal interpretation.
Also, if you plan to operate a digital mode, you’ll likely need some sort of computing device. Even though I rarely operate digital modes in the field, I often pack my Microsoft Surface Go tablet in case I change my mind.
My Microsoft Surface Go tablet
In addition, I like logging directly to N3FJP’s Amateur Contact Log application directly in the field to save time submitting my logs later. Soon, I’ll be using the new HAMRS field log on my iPhone.
Speaking of logging…
A means of logging
I like compact notepads like Muji and Rite In The Rain for field use.
As simple as it is, it’s very important to take at least some paper and a pencil for logging your contacts. I like using small, pocket-sized Muji notebooks (affiliate link) for logging, and if the weather is even a little questionable, I’m a huge fan of getting my contacts down in Rite In The Rain mini notebooks (affiliate link) or notepads using a good old-fashioned pencil.
I like logging to paper and sometimes simultaneously logging to my Microsoft Surface Go. I have completed phone-only field activations where I only logged to my Surface Go tablet: in those cases, I snap a photo of my N3FJP call log, just in case something happens to my tablet between the field and the shack! Having endured enough technology failures, it gives me peace of mind to have at least one other backup.
Keep in mind that when you’re activating a park or summit, the folks calling you are relying on you to submit your logs to the appropriate programs so that they can get credit for working you. Many times, this might also help their awards for a state, county, or grid square. Always submit your logs after an activation even if you didn’t make enough contacts to validate the activation (POTA requires 10 contacts, SOTA requires 4 logged). It helps other folks out.
A pack or case
If you have a field radio kit, you’re going to need a means to organize and contain it for transport. There are at least three types of systems used for field kits.
A backpack or soft-sided case
My GoRuck BulletRuck is a brilliant SOTA pack
Since I enjoy the option of hiking with my radio gear, I love using backpacks. Although I’ll speak to this more next month in “Part 2,”, I choose quality packs that have at least one waterproof compartment and are comfortable to carry on long hikes. I also try to look for packs with Molle or some sort of external strapping so that I can attach portable antenna masts or even my hiking poles to the exterior of the pack.
A waterproof case or flight case
Ruggedized, weatherproof cases come in all sizes. This Pelican 1060 can house my entire KX1 radio kit.
Many field operators who want extra protection for their gear––especially when they don’t plan to hike or carry their gear long distances to the operating site––like hard-sided cases. I have built field radio kits in waterproof Pelican cases and appreciate knowing that I could drop my kit in a whitewater river, and it would likely survive the adventure unscathed. If you are one of these operators, look for quality watertight cases from brands like Pelican and Nanuk with interiors lined in pick foam padding that allows you to perfectly accommodate and safely protect your radio and accessories.
Portable ready-to-deploy cases
Although this option is almost outside the scope of this article, many emergency communications enthusiasts love having their gear loaded in rugged, portable––often rack-mounted and hard-sided––cases that they can simply open, hook to an antenna, and get right on the air. These systems are often the heaviest, least “portable,” and less suited for long distance hikes, but they’re often completely self-contained, with all of the components, including the power, hooked up and ready to go on a moment’s notice. While a system like this would be impractical for many Summits On The Air sites, it could be ideal for a park or island activation where you’re never that far from your vehicle.
Optional: Antenna cable
An ABR Industries RG-316 cable assembly
This doesn’t sound like an option, but it’s true. I’ve often operated my Elecraft KX3, KX2, and KX1 without a feedline at all: I simply attached two wires to a BNC binding post, and connected that to the radio. It makes for a super-compact setup.
Even an 8-12 foot feedline can make it easier to configure your operating position in the field. If you want to keep the feedline as low-profile as possible, especially if you’re operating QRP, consider investing in a quality RG-316 feedline terminated with the connector that fits your radio and antenna.
Optional: Antenna Tuner/Transmatch
A portable ATU with RF-sensing like the Elecraft T1 will give you an amazing amount of frequency agility. I’ve been known to use the T1 to tune my CHA Emcomm III random wire antenna on 160 meters..
Again, this topic could easily warrant a multi-part series of articles, but I’ll sum this one up in a nutshell: while I love (and even prefer) using resonant antennas that require no antenna tuner, I almost always carry a radio with a built-in ATU or an external portable ATU like the Elecraft T1 or ZM-2.
Why? Because an ATU will give you a certain amount of frequency agility or freedom. If I’m using an antenna that’s resonant on 40, 20, and 10 meters, but there’s a contest that day and the bands are incredibly crowded, I might use the ATU to find a match on 30 meters or 17 meters, thus finding a little refuge and space to operate. Also, sometimes antenna deployments aren’t ideal––due, for example, to site limitations such as dense vegetation that may alter the antenna deployment and thus its resonance. An ATU can at least keep your transceiver happy with the SWR when your resonant antenna might not be perfectly resonant.
But the main reason I carry it? A portable ATU gives you operational flexibility.
QRP or QRO?
I have operated QRO in the field with my KXPA100 amplifier on Field Day.
Its good to keep in mind that many of the station accessories listed above need to be matched to the output power of your transceiver and modes you use.
Many ham radio friendships have been placed in jeopardy over the question of either using QRP (low power) or QRO (high power) for field operations. This is a shame. Some operators have very strong opinions, but the truth is, there is no right or wrong answer.
In the spirit of full disclosure, I operate 97% of the time at QRP power levels––in my world, this means five watts or less. Personally, I enjoy the challenge of low-power operating. But I also appreciate the portability QRP gear offers.
The wee Mountain Topper MTR-3B
Speaking pragmatically––and this fact really isn’t open to debate––QRP and lower-power transceivers and accessories tend to be more efficient, more compact, and lighter than their higher-power siblings.
Most of my QRP transceivers weigh anywhere from two to five times less than their 100-watt equivalents. If you’re operating mobile (from a vehicle or camper/caravan, for example), an eight to twelve pound difference might not be a big deal. But the moment you’re hiking several miles to a mountain summit, weight becomes an important factor.
QRP transceivers have modest power requirements: everything from battery, to antenna, and even to tuners, are smaller, lighter, and more compact.
When operating QRP, you don’t have to worry as much about RF coming back to the radio from, say, an end-fed antenna. If I’m pushing over 20 watts into an end-fed half wave or end-fed random wire, I’ll likely want an in-line RF choke to keep some of that energy from affecting my transceiver or giving me an RF “tingle” when I touch the radio chassis or my key. Too much RF coming back to the transceiver can also affect things like electronic CW keying. But at five watts? I don’t worry. This is almost a non-issue, unless your transceiver happens to be very RF-sensitive indeed.
And even though I’m predominantly a QRPer, I definitely do pack radios like the 50-watt Mission RGO One and occasionally my Elecraft KX3 and KXPA100 100-watt amplifier, especially for an event like Field Day where my club is operating at higher power. I simply size up my gear appropriately. Again, this is especially important with your antenna, feed line, ATU, and battery selections.
If you primarily activate parks and are never far from your vehicle, it’s quite easy to accommodate a 100 watt transceiver like an FT-891, for example. Of course, if you wish to operate low-power and save your battery, simply turn down the output power. If you plan to hike a lot with your gear, then get your mind around QRP!
Stay tuned for Part 2!
In Part 2 we’ll dig into some of the details, looking at different approaches to field radio kits and some guidance and suggestions based on my real-life experience (read: operating mistakes).
On October 10, I took delivery of a CW Morse (https://cwmorse.us/) “Red Single Paddle Morse Code Key With Base” (https://cwmorse.us/product/red-single-paddle-morse-code-key-with-base/) which Tom Witherspoon, K4SWL, had sent me to review for this website. CW Morse had sent Tom several keys to review and Tom, knowing I am a fan of single-lever paddles, sent me the CW Morse single-lever paddle to review.
I will admit it: I wasn’t expecting much from a 3-D printed CW paddle, but I was very surprised by the quality of the build and the feel of the paddle.
The “Red Single Paddle Morse Code Key With Base” is a nice mix of 3-D printed frame, lever, fingerpiece, and cover with steel ball bearings, metal contacts, steel centering springs, and a heavy steel base. (See photos, above.)
The mailman delivered the paddle on October 10 and I started using it almost immediately as a cootie-key / sideswiper to hunt Parks on the Air (POTA) activations. (A cootie-key or sideswiper is a manual key in which the operator moves a paddle alternately side-to-side to manually create the dots and dashes of Morse Code.) The paddle worked very well as a cootie and I made six POTA QSOs using the paddle on the afternoon of the 10th. Unfortunately, when I tried to use the paddle for my nightly ragchew-QSO with K8RAT, the paddle stopped centering properly and I had to switch to another key to finish the QSO. A day or two later, I studied the CW Morse key and found that I was able to loosen the nut at the lever pivot-point a little bit to reduce drag. After this simple adjustment, the paddle has worked beautifully without further need for adjustment.
The “Red Single Paddle Morse Code Key With Base” features adjustable gaps on both sides of the lever. These gaps are easily adjusted using the supplied Allen wrench or with bare fingers. The spring tension is not adjustable and the paddle’s feel is pretty light.
The steel base, while small, is quite heavy and the four rubber feet provide excellent traction on my radio desk. I have a pretty heavy fist and this paddle is almost heavy enough that I can send with my right hand without holding the paddle with my left hand.
Now, a disclosure: I have been using semi-automatic bugs and fully-manual cootie keys so long now that my keyer fist is absolute rubbish. I did use the paddle to drive an electronic keyer for one ragchew-QSO and the paddle worked very well in that mode and it had a nice feel–any mistakes made in keying were not the fault of the paddle but of my own inability anymore to judge how long to hold the dash-paddle.
I’ve been using this paddle as my go-to cootie-key for over half a month now and as a cootie key the “Red Single Paddle Morse Code Key With Base” excels. The gaps were easily adjustable and the feel of the paddle as a cootie is just fantastic. This key has, at least for the moment, become my favorite hamshack cootie-key.
The “Red Single Paddle Morse Code Key” can be removed from the steel base for field or portable use and I did remove the key from the base to try it in this configuration. Unfortunately, I didn’t like the feel of the paddle in my left hand, primarily because the two mounting rails make the key feel awkward in my hand. CW Morse does offer a dual-lever field paddle (https://cwmorse.us/product/pocket-double-paddle-morse-code-key/) and I think a similar design with a single lever would make an excellent field paddle or cootie key. (Read about Tom Witherspoon’s experience with the dual-lever field paddle here: https://qrper.com/2020/10/pota-field-report-pairing-the-icom-ic-705-with-the-elecraft-t1-and-cw-morse-pocket-paddles/.)
Bottom Line: I have been very pleased with the “Red Single Paddle Morse Code Key With Base” and I can recommend it for any CW operator who needs an inexpensive but well-made single-lever paddle.
This year, at the Four Days in May (FDiM) Dayton QRP gathering, I had the pleasure of meeting Dennis Blanchard (K1YPP) and his wife, Jane, as Blanchard signed copies of his book, Three Hundred Zeroes: Lessons of the Heart on the Appalachian Trail. I had previously heard about Blanchard’s book, and it was great meeting the author in person. Both he and his wife were most friendly, and I instantly felt a connection–after all, he is a fellow QRPer!
As a result of this meeting, I recently decided to purchased a copy of Three Hundred Zeroes on my Kindle eBook reader. Though I’ve always been a fan of turning pages on a traditional book, the eReader does afford one instant gratification, as you can order it on-the-go and start reading immediately. And that’s exactly what I did…
The result? I’m very glad I took the time to read Blanchard’s Three Hundred Zeros. Though I don’t like to spend much time away from my young family at present, I’ve always thought it would be a wonderful challenge and adventure to through-hike the AT (Appalachian Trail); reading this book was a vicarious opportunity to do so. Indeed, my favorite trail, the BT–the Bartram Trail, which follows the path of early American naturalist and explorer William Bartram–which I hike when I can, and whose NC chapter I’ve served as a board member for nearly 10 years now, parallels the AT at different points. So the temptation to hike (and QRP, of course) continues.

Blanchard’s book gives me hope. Three Hundred Zeroes is a well-documented, informative, and–despite his truly serious heart condition–often humorous journal-style account of his successful thru-hike of this 2176 mile trail. His writing style is very informal and likeable, focusing on the many personal interactions that make the trail hiker’s experience unique, and interweaving his day-to-day accounts with trail lore and history.
In contrast with the arduous journey Bill Bryson describes his well-known (and hilarious) book, A Walk in the Woods, in Three Hundred Zeros Blanchard calmly and routinely deals with misadventures and hair-raising encounters with wildlife, rolling with the punches and somehow emerging unscathed. He describes the journey as “long stretches of boredom, punctuated by brief moments of excitement” in the lively and unpredictable form of bears, mice, snakes, and even other hikers, to some degree. Blanchard was obviously a great hiking companion, thus rarely hiked alone–no doubt, other hikers sought his company.

With QRP in mind, I had a few questions for Blanchard after reading his book. He has kindly taken the time to respond to QRPer‘s questions, as follows.
QRPer: I always thought that the AT would be a lonely place, but your book certainly changed my mind. Were there many stretches of trail where you were completely alone while trekking or camping at night?
Blanchard: There were times when I was alone for extended periods. However, “alone” is a relative term. Throughout the day I would encounter other hikers going in the other direction, or people that were slower or faster than I. In 180 days on the trail, I think I had three nights when I camped alone.

QRPer: What was your favorite stretch of trail?
Blanchard: That’s difficult to answer…The trail is so varied and weather can change one’s views of any section. For me, it was a coin toss between the New Hampshire White Mountains and the 100 Mile Wilderness in Maine. The remoteness of both areas was just so spectacular. Of course the high altitudes made for great antenna opportunities as well.
QRPer: Did you bring a radio to listen to local AM/FM or shortwave?
Blanchard: For most of the hike, I carried a Yaesu VX-1R 2/440 handi-talkie. I think I used it about three times on two-meters. In a few situations, such as up in the White Mountains, I used the VX-1R to tune in NOAA for weather news. It also has AM/FM and on a few very rare occasions, I tuned into local stations for news. Would I carry it again? I don’t know. It is wise to have something for emergencies, and the radio wasn’t too big or heavy, but it was extra weight.
QRPer:Specifically, what ham gear did you take with you? Do you have a photo?
Blanchard:As noted in the book, I did carry a home-brewed 80/40 meter CW rig for the first 600 miles. For the rest of the hike I carried Steve Weber’s ATS-3A. The radio was powered by six Energizer disposable lithiums, in a home-brewed battery pack. The pack could also charge my cell phone and power the 2-meter VX-1R radio. I used a 51 foot random wire for the antenna and some counterpoise wire, usually about 15 feet. Altogether, the gear weighed around two pounds.
QRPer:If you were to do the hike again, would you take the same equipment?
Blanchard: I’m not certain I would carry the VX-1R again. I didn’t use it much and it is extra weight. However, the NOAA weather, and 2-meter capability could prove extremely useful in an emergency.
QRPer:What was it like coming back off the trail once you completed it? Any especially notable things about how you perceived the world around you? Did it change you? Any culture shock?
Blanchard: The only real “culture shock” was riding in automobiles. Everything seemed to move so quickly. I much more enjoy walking and biking now. I would be happy if I never had to drive again.

QRPer: How many other hams did you meet on the AT who were either through-hiking the AT, or hiking sections?
Blanchard: Since we [hikers] don’t wear being a “ham” on our sleeve[s], I can’t really say how many hams I encountered. The few that I was aware of were mostly section hiking. One benefit of setting up my QRP station along the way was public visibility for ham radio. On a number of occasions I inspired my fellow hikers to look into ham radio when they returned home. I’ve even had a few readers of the book write me to tell me they went off and got a ham license based on inspiration from the book.
QRPer: If any other QRPers are inspired by your story, and are thinking about hiking the entire AT, how much money should they budget for such an adventure? Based on what I read, there are a number of budgetary considerations for shuttles, food, gear, and the like.

Blanchard: The answer to this question depends on how many “creature comforts” one wishes. Hiking as I did, with stops along the way about every 5-10 days, can cost about $1-$3 a mile. Those on a tight budget could do it for much less, and those that enjoy getting to hotels and eating in fancier places could spend more. Most of the shuttles were really not that expensive, at least those that cater specifically to hikers. The hostels are a real bargain, compared to standard hotels, but one may have to tolerate annoyances, such as snoring and people coming and going at unusual hours. If you’re a light sleeper, this could be an issue.
QRPer: On zero days [based on your descriptions] it seems like hikers simply stuff themselves with food. I’m really curious what you typically ate on the trail?

Blanchard:The short answer is: I ate everything. I’m not fussy, and don’t have any diet limitations. If someone is diabetic, or vegetarian, it is still possible to undertake such a hike, it just might require more preparation. My typical day was a few Pop Tarts first thing in the morning, or hot oatmeal on cold days, followed by an on-trail mid-morning snack, such as a Snickers Bars or trail mix.
Lunch was usually something that didn’t need cooking. Roll-up tortillas, or bagels with peanut butter won out most of the time. In the colder weather, bagels and cream cheese was a favorite. Gatorade powder mix, or hot chocolate in cold weather, was my favorite drink for lunch.
The evening meal was usually a pasta-based affair, or couscous. I really preferred the couscous; it is very light to carry, needs very little energy to cook, and is loaded with nutrients. I would usually stir in some dried vegetables with it, or dried meat. As a side I would carry a dried sausage, such as pepperoni, which could also serve as a snack for lunch. I usually carried some desert items as well, such as cookies or dried fruit. Of course energy bars would supplement all of this along the way. Many hikers preferred candy bars, but I tried to avoid them in the warmer weather since they melt.
Overall, even though the diet sounds bland, it wasn’t bad. Of course, whenever we hit a town, I would stuff on everything in sight. I actually did eat well, but couldn’t find enough calories to maintain my weight. I ended up losing 35 pounds at the end of the hike and looked like a refugee.
Well, Dennis–all I can say is that I hope you’ve gained back some of those lost pounds, continue to be in good heart-health, and are able to enjoy a little QRP on your forthcoming hikes. Thanks very much for taking the time to answer our questions; we wish you the very best!
