Anatomy of a Field Radio Kit Part 2: Kit Types, Preparedness, and the Golden Rules

The following review was first published in the July 2021 issue of The Spectrum Monitor magazine. Read Anatomy of a Field Radio Kit Part 1 here.


Part 2: Anatomy of a field radio kit

Last month, I took us down the rabbit hole of field radio kits by discussing some of the most basic components of a field radio kit in Part 1.

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.

How I pack out my GoRuck GR1 for POTA and Overnight Travel

As I’ve mentioned a number of times on QRPer and on the SWLing Post, I’m a pack geek.  I enjoy organizing and packing my gear for field radio activities and travel.

Last week, I made a very quick overnight trip to visit my parents. My time during this trip was very limited and I did not plan to fit in an activation, but Monday morning, I was able to knock out an errand very early and that freed up a couple of hours in the early afternoon. Fortunately, prior to leaving my QTH, I decided to pack a few travel items in my GoRuck GR1 pack along with a field radio kit built around my Elecraft KX2.

I never leave home without a field radio kit because I never know when an opportunity to play radio might happen.

On the way home Tuesday, I popped Lake Jame State Park and fit in a quick, last minute activation.  Moments before arriving at the lake, I received a request from one of my YouTube subscribers asking if I would make the occasional video showing what’s in my radio packs and field kits.

I’ve been meaning to make these videos but, frankly, often forget when I arrive at a park or summit because I’m just a little too focused on starting my activation.

Since I had some overnight items in my pack, it wasn’t a typical SOTA or POTA field kit, but I decided to make the video anyway. After all, I love watching videos about how others pack and organize their radio and travel kits. But then again, I’m a pack geek. I did mention this right–?

Although I’m not always the neatest person (my wife is probably chuckling at this gross understatement), I’m a meticulous and very organized pack geek. What you see in the video is exactly how I pack when no one is looking. 🙂

I’ll add here that if you’re interested in field radio kits and packs, I’d encourage you to check out my Anatomy of a Field Radio Kit series; Part 1 has already been published and Part 2 will be posted later this week.  In Part 2, I take a much deeper dive into safety gear I take on SOTA activations.

Gear

In the video, I mention that I would attempt to link to all of the items in my pack. I spent time sorting out links this morning; many links go straight to the pack manufacturer because the packs I use typically have no distributors other than the manufacturer, I have also purchased a lot of the smaller items on Amazon, but many can be found in big box stores like Walmart, Target, Canadian Tire, etc.

Activation items

Extra Travel Items in the GR1

Health & Safety Items

US Pack Companies I love…

  • Red Oxx (my favorite overall)
  • Tom Bihn (brilliant tailored/urban travel bags)
  • GoRuck (note that not all are made in the USA these days)
  • Spec Ops Brand (incredible value for tactical packs)

If I missed something, let me know in the comments.

Video

Like all my videos, this one us unscripted, made in one take (unedited), and also has no ads:

Out of order…

So this video was made prior to an activation at Lake James last week. I’ve mentioned before that my Internet speeds at the QTH are worse than dismal, but since this pack video was relatively short, I was able to upload it ahead of the activation video (it took 1.5 days to upload this 2GB file).

The activation video will be published in another week or so depending on my access to some proper broadband service.

Any other pack geeks out there?

I would love to share photos, descriptions, and/or a video of how and what you pack for field activations.  If you’re interested in submitting a guest post, please do so!

Also, I’d love to hear about your favorite packs and how well they’ve held up with time.

Feel free to comment and thank you once again for hanging out here at QRPer.com!

Anatomy of a Field Radio Kit Part 1: Basic components and advantages of going QRP

The following review was first published in the June 2021 issue of The Spectrum Monitor magazine:


Part 1: Anatomy of a field radio kit

by Thomas (K4SWL)

Whether it’s the ARRL Field Day, Winter Field Day, a QRP contest, or, more likely, a Summits On The Air or Parks On The Air activation, I look for any and every excuse to hit the field with my radios.

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)

And if you’re primarily a CW operator, you’ll have some incredibly compact radio options like the CW-only Mountain Topper MTR-3B or 4B, or the Elecraft KX1 (used).

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 it in 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 Antenna for 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!

Packtenna 9:1 UNUN Random Wire
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

Vibroplex sells 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 Enterprises also 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!

In fact, some antennas are no more than a bit of speaker wire matched with a good ATU.

A power source

A 3Ah Bioenno 12V LiFEPo4 powering my LD-11 transceiver

I’ll keep this point brief because we recently covered the topic of batteries in detail in our previous feature.

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

Again, check out our Portable Power Primer for a deep-dive into the world of portable power.

A key, mic, and/or computing device

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).

The Icom IC-705 is getting a rugged, weatherproof case

I love my Icom IC-705–just check out my review if you need proof–and I love taking it to the field.

It’s a very compact radio for being so incredibly feature-rich and I love the portability simply using the attached battery pack. Since I operate mostly 5 watts with all my rigs, I rarely bother bringing an extra battery with it in the field.

With that said, I worry about the IC-705 more than any other portable radio I take to the field.

For one thing, it’s a $1,300 US rig. That’s not chump change for most of us.

The IC-705 also has a large color touch screen display. In fact, it’s the only field portable radio I own with a touch screen display. The touch screen has a matte finish and is pressure-sensitive rather than capacitive like most tablets and smart phones. Many capacitive screens use something like Corning Gorilla Glass which is actually quite durable and resistant to scratching and puncturing. It’s not perfect by any means (I think we’ve all shattered or broken a capacitive screen) but they’re more durable than the pressure-sensitive screen on the IC-705.

The IC-705 chassis feels very solid and it seems to be sealed very well, but at the end of the day, the chassis is make of a durable plastic material which is prone to scratching and I have to assume easier to damage than, say, the FT-817ND’s metal chassis.

Ray Novak with Icom America is a friend and when I took delivery of the IC-705 I mentioned how I felt protective of it in the field, fearing I might damage it in my backpack or even tumbling off a rock during a SOTA activation. Ray basically said that, as with everything new, I’ll get used to it and become more comfortable in the field.

I’ve never completely gotten there, though, and I’ve had this radio for a good nine months now.

I’m a backpack guy, so when the IC-705 is packed for field action in one of my Red Oxx or GoRuck backpacks, I house the IC-705 in a $14 Ape Case Camera insert. It’s not perfect, but fits it well.

I mentioned in my review that I eventually wanted to find a better solution.

I’ve looked at a number of 3rd party “cages” and numerous readers and YouTube channel viewers have recommended the IC-705 Carry Cage by Peovi. From what I’ve seen, it looks to be the best of the bunch, but it doesn’t do a lot to protect the lower back portion of the radio–the part of the chassis that meets a surface. I feel like it’s not quite what I’d want, thus hard to justify $135 for it (Peovi, send me a loaner to try out if you wish to prove me wrong.)

Other aluminum and 3D printed cages seem to add too much bulk to the radio or obstruct some of the most common connection points on the sides (antenna, key, ATU control cable, speaker/mic, etc.).

The form factor of the IC-705 is otherwise fine, but its chassis design does make it a little more difficult to protect than, say the KX3 or FT-817/818.

I’ve come to the conclusion that most of the time I use the IC-705, it’s on POTA activations where it’s sitting on a picnic table. Although I’m a backpack guy, this is the perfect time to kit out a ruggedized, weatherproof case.

Which case?

I started looking at cases last week and, being transparent, I’m a bit of a snob about these things. I want a case that’s made by a reputable company to protect the ‘705–I’m not going to hunt for one at a Walmart or Canadian Tire.

I’ve owned a few Pelican cases over the years. All have been smaller ones like the Pelican 1060 I’ve used with my KX1s.  Pelican has a solid reputation and are certainly the best-known in this market and Pelican still makes all of their cases in the USA.

I’ve also been looking for a reason to try the case manufacturer, Nanuk. They design and manufacture all of their products in Canada and have a great reputation. Their pricing is the same or, at times, even slightly more competitive than Pelican for comparable cases.

Although I rarely care about the color, I decided I wanted a light grey or silver color for this case as opposed to black (my standard default), yellow, or another bright color.

In the Nanuk case line, their Nanuk 915 was probably the correct size to give the IC-705 enough padding, and allow space for all other accessories and items I’d need in the field.

In the Pelican line, I liked the Pelican 1400.

I was just about to pull trigger on the Nanuk 915 via the Nanuk website and decided it would make sense to also check pricing on Amazon.com for both units.

The Nanuk 915 was about $76 (affiliate link) with the pick foam insert–a great price–but only that price in the black color. The silver color was about $97.

I then checked the Pelican 1400. The black case with foam insert was $95, but the silver one was $79.95. Since I really wanted silver and since I had a slight preference for the 1400’s dimensions, I purchased the Silver Pelican 1400 (again, affiliate link).

Amazon offers free no-hassle returns, so once I receive the 1400 next week, I’ll carefully measure and double check everything before digging into the pick foam!

A case for advice…

I’ve never kitted out a larger Pelican case with radio gear. I would welcome any and all advise from those of you who have. Since it’s easy to remove pick foam, but impossible to put it back if done incorrectly, I really want to follow best practices.  Please comment!

Mark discovers an affordable IP67 rated protective case for the Yaesu FT-891

Many thanks to Mark Hirst who writes:

Thomas,

I got a new FT-891 recently and wanted a protective case for taking it out into the field.

A mixture of internet searches and Amazon algorithms turned up this very affordable case which closely matches the size of the radio, as the enclosed photograph shows.

It uses the familiar pick and pluck foam, although in two layers.

The base layer is a bit thin, so I might put a layer of rigid plastic over it to stop the feet of the radio pushing down to the outer case.

I prioritised the side wall thickness opposite from the carry handle, as the case is designed to sit on its side like a briefcase.

Wow, Mark! I do love the size of this case and the fact that it fits the FT-891 so perfectly.

Recently, I’ve been thinking about building out a case to hold one of my smaller QRP transceivers (the KX1, KX2, or MTR3B) in the field to be used when it’s raining. Perhaps this has been on my mind because I’ve been enjoying nearly 5 straight days of rain and fog! A case like this would be an affordable solution and I wouldn’t feel terribly bad about drilling through the case to mount antenna, key, mic, and headphone ports.

Thank you again for the tip!

The Elecraft KX1: Reunited and it feels so good.

The Elecraft KX1

A few weeks ago, I published a post about radios I’ve regretted selling or giving away.

Number one on that list was the Elecraft KX1.

Within a couple hours of posting that article, I had already purchased a KX1 I found on the QTH.com classifieds. It was, by any definition, an impulse purchase.

The seller, who lives about 2 hours from my QTH, described his KX1 as the full package: a complete 3 band (40/30/20M) KX1 with all of the items needed to get on the air (save batteries) in a Pelican 1060 Micro Case.

The KX1 I owned in the past was a four bander (80/40/30/20M) and I already double checked to make sure Elecraft still had a few of their 80/30 module kits available (they do!).  I do operate 80M in the field on occasion, but I really wanted the 80/30 module to get full use of the expanded HF receiver range which allows me to zero-beat broadcast stations and do a little SWLing while in the field.

The seller shipped the radio that same afternoon and I purchased it for $300 (plus shipping) based purely on his good word.

The KX1 package

I’ll admit, I was a bit nervous: I hadn’t asked all of the typical questions about dents/dings, if it smelled of cigarette smoke, and hadn’t even asked for photos. I just had a feeling it would all be good (but please, never follow my example here–I was drunk with excitement).

Here’s the photo I took after removing the Pelican case from the shipping box and opening it for the first time:

My jaw dropped.

The seller was right: everything I needed (and more!) was in the Pelican case with the KX1. Not only that, everything was labeled. An indication that the previous owner took pride in this little radio.

I don’t think the seller actually put this kit together. He bought it this way two years ago and I don’t think he ever even put it on the air based on his note to me. He sold the KX1 because he wasn’t using it.

I don’t know who the original owner was, but they did a fabulous job not only putting this field kit together, but also soldering/building the KX1. I hope the original owner reads this article sometime and steps forward.

You might note in the photo that there’s even a quick reference sheet, Morse Code reference sheet and QRP calling frequencies list attached to the Pelican’s lid inside. How clever!

I plan to replace the Morse Code sheet with a list of POTA and SOTA park/summit references and re-print the QRP calling frequencies sheet. But other than that, I’m leaving it all as-is. This might be the only time I’ve ever purchased a “package” transceiver and not modified it in some significant way.

Speaking of modifying: that 80/30 meter module? Glad I didn’t purchase one.

After putting the KX1 on a dummy load, I checked each band for output power. Band changes are made on the KX1 by pressing the “Band” button which cycles through the bands one-way. It started on 40 meters, then on to 30 meters, and 20 meters. All tested fine. Then I pressed the band button to return to 40 meters and the KX1 dived down to the 80 meter band!

Turns out, this is a four band KX1! Woo hoo! That saved me from having to purchase the $90 30/80M kit (although admittedly, I was looking forward to building it).

Photos

The only issue with the KX1 was that its paddles would only send “dit dah” from either side. I was able to fix this, though, by disassembling the paddles and fixing a short.

Although I’m currently in the process of testing the Icom IC-705, I’ve taken the KX1 along on a number of my park adventures and switched it out during band changes.

Indeed, my first two contacts were made using some nearly-depleted AA rechargeables on 30 meters: I worked a station in Iowa and one in Kansas with perhaps 1.5 watts of output power.

I’m super pleased to have the KX1 back in my field radio arsenal.

I name radios I plan to keep for the long-haul, so I dubbed this little KX1 “Ruby” after one of my favorite actresses, Barbara Stanwyck.

Look for Ruby and me on the air at a park or summit near you!

Scott’s Elecraft KX3 Go-Box

[Note: this article was originally posted on my shortwave radio blog, The SWLing Post.]

Many thanks to Scott (AK5SD) who shares the following photos and bill of materials for his custom Elecraft KX3 go-box:

Bill of materials

The panel was custom laser cut by Front Panel Express. I have the CAD
file and I’m willing to share it with anyone who wants to reproduce my effort.

Amazon.com
Case B&W Type 1000 Outdoor Case with SI Foam
You won’t use the foam, so you can buy the version without it if you can find it cheaper.

Battery Anker Astro Pro2 20000mAh Multi-Voltage (5V 12V 16V 19V)
Portable Charger External Battery Power Bank
Avoid look alike batteries and the next generation model from Anker. The newer Anker
battery is only capable of delivering 1.5A from the 12V supply. Two look alike batteries
I tried did not have the auto-off feature that the Anker does.

Vetco.net
ACC2 and I/Q Jacks 2 x 2.5mm Stereo Jack Panel Mount (PH-666J-B)
Phone, Key, and ACC1 3 x 3.5mm Stereo Jack Panel Mount (High Quality) (PH-504KB)
Mic Jack 1 x 3.5mm 4 Conductor Jack Panel Mount (PH-70-088B)
12V IN and CHG IN 2 x 2.1mm DC Power Panel Mount Jack (PH-2112)
12V OUT 1 x 2.5mm DC Power Panel Mount Jack (PH-2512)

You also need plugs and wire for interconnects. I bought some 2.5mm (CES-11-5502)
and 3.5mm (PH-44-468 for stereo, PH-44-470 for 4-conductor) audio cables with right
angle plugs and just cut them to use for the signal lines going to the KX3. I did the same
thing for the 2.5mm (PH-TC250) and 2.1mm (PH-TC210) power cables. A couple of
caveats are in order. The Phone, Key, and ACC1 interconnects require low profile
right angle connectors. The cables I listed above won’t work. Vetco part number
VUPN10338 will work. The power cables I’ve listed above use 24 gauge wire. This
is a little light, but the runs are small so I think it is OK. You can use higher gauge
cables if you can find a source.

USBfirewire.com
USB OUT USB 2.0 Right Angle Extension Cable (RR-AAR04P-20G)

Digikey.com
L Brackets 8 x Bracket Rt Ang Mount 4-40 Steel (612K-ND)
These L brackets are used to mount the KX3 to the panel and the panel to the case.
For mounting the KX3, I use a little piece of stick on felt on the bracket to protect the
KX3’s cabinet from damage. Replace the KX3’s screws with #4-40 Thread Size, 1/4”
Length Steel Pan Head Machine Screw, Black Oxide Finish (see below). For the panel
mounting, use #6-32 Thread Size, 3/16” Length self tapping sheet metal screw. You
may need to cut the tip off in order to not puncture the outside of the case.

RG316 BNC Male Angle to BNC Female SM Bulkhead Coaxial RF Pigtail Cable (6”)
This is not the original interconnect I used for connecting the KX3’s antenna output to
the panel. However, I think it is a better option for new designs. The caveat is that you
will need to verify the hole in the panel matches the bulkhead connector on this cable.
There will be a little loop in the cable when you are done, but that is fine.

Screws for Countersunk Panel Holes 8 x FMPPK0403 – 4-40 x 3/16
Screws for USB Connector *** 2 x FMPPK0406 – 4-40 x 3/8

I’m pretty sure these are the right length for the USB connector. I am doing it from memory.

Soundmatters foxL DASH A Wireless Bluetooth Soundbar (OPTIONAL)

Sonoma Wire Works GJ2USB GuitarJack 2 USB Portable Audio Interface (OPTIONAL)
(Make sure you get the USB model, not the 30-pin model.)

This is optional if you want a built-in sound card interface for a waterfall display using iSDR. Make sure to eliminate the holes in the upper left corner of the panel if you are not installing. You will also need 2.5mm x 10mm screws to mount this to the bottom of the panel (see below).

bhi Compact In-Line Noise Eliminating Module (OPTIONAL)

In my opinion, the KX3’s noise reduction is totally ineffective for SSB communications. This external noise reducing DSP is one solution, albeit an expensive one, to that problem. It is only for SSB, not CW or digital modes. It is also available from GAP Antenna Products.

Scott: you have done a beautiful job here and have spared no expense to make a wonderfully-engineered and rugged go-box. No doubt, you’re ready to take your KX3 to the field and enjoy world-class performance on a moment’s notice. 

Though I’ve never used them personally, I’ve noticed others who have taken advantage of the Front Panel Express engraving service–certainly makes for a polished and professional front panel.

Again, many thanks for not only sharing your photos, but also your bill of materials which will make it much easier for others to draw inspiration from your design!

Speaking of designs, when I looked up Scott on QRZ.com, I noticed that he also sports a QSL card (above) designed by my good friend, Jeff Murray (K1NSS). Obviously, Scott is a man with good taste!
