Last week, my family hopped in the car and took an eight hour drive to the Outer Banks of North Carolina.
We’ve had such a busy 2021 that we decided to take a full week prior to Christmas and fit in some proper vacation and family time.
We love going to the coast off-season to avoid big crowds. Turns out, we chose well, too: it’s as is we have the whole of the Outer Banks to ourselves. Other than a couple days with some “invigorating” weather (which we actually enjoy) it’s been absolutely spectacular.
While radio plays an important role in any travels, my family time always takes priority. The good thing about activating parks is that radio and family time often go very well together!
On Friday, December 17, 2021, my daughter Geneva (K4TLI) and I decided to spend the day together while my wife and other daughter worked on an art project at our rental cottage. We had a few loose plans, but mainly wanted to fit in a nice beach walk, possibly discover some new scenic spots, and enjoy a take-out lunch together.
She very much liked the idea of fitting in a bit of POTA, so we hit the field with two sites in mind.
The plan
My Subaru is still in the body shop getting repaired after a bear decided to open the doors and make himself at home, so we have a Toyota Camry rental car on this trip. It’s been a great vehicle for sure, but its trunk space is limited and we packed quite a lot of food knowing local restaurants would be closed this time of year.
We all limited our luggage and I limited the amount of radios and gear I took. I could write an entire article about my holiday radio and antenna selection process (seriously, I put too much thought into it) but in a nutshell I limited myself to two radios and two antennas.
I don’t often read comments in ham radio forums and discussion groups.
Recently, however, I was trying to dig up information on a field antenna design and the search results lead me to two articles and discussions on two of the most popular ham radio sites on the internet.
I read through the comments and (you might have guessed) was really disappointed with the number trolls who seemed to thrive in that fertile environment. It blows my mind that discussions like these seem completely unmoderated. I assume it’s a conscious decision since we seem to live in a society that rewards drama and division–I assume this leads to more site traffic and thus more revenue.
It’s a shame. It would be incredibly discouraging to a new ham who is reading the same article and comments looking for ideas. Gives one the impression the hobby is full of (I’ll keep my language clean here) schmucks.
But I digress…
What was perhaps equally discouraging were all of the comments from those who were trying to explain to the authors how the antenna design in their article simply wouldn’t work. Even when the author posted positive results/data from having used the antenna.
While not all of the naysayers were being rude–and sometimes in their roundabout way I’m sure they felt they were being helpful–I can’t help but feel sorry for them.
I had a conversation recently with a ham who upgraded his license for HF privileges primarily to do park activations in the POTA and WWFF programs.
He mentioned that he had a few successful park activations under his belt but was left scratching his head on a couple of occasions when he attempted a Park-To-Park (P2P) contact but could not be heard by the other activator.
He did all of the right things: announced his call sign followed by “Park To Park” twice and was patient while the activator worked a small pile-up.
In one case, he said the other operator had an incredibly strong signal–and having always heard, “if you can hear them, you can work them“–he was really baffled that he couldn’t make contact especially being a desirable P2P. His activations were successful so he knew it wasn’t an equipment issue.
He asked for my input, so I thought I might share a few points here as this is not at all uncommon–please comment if you think of others:
Big power, small antenna
Some activators operate mobile and don’t actually deploy their gear in the field. They simply drive up to a site, turn on their mobile HF rig in the car, and start making contacts with the mobile whip antenna mounted on their vehicle. There’s nothing wrong with this approach in the POTA program (just keep in mind mobile activations are not allowed in SOTA). Mobile activators can rack up numerous park activations in one day often regardless of weather or any site restrictions.
Mobile vertical antennas like Screwdrivers, Hamsticks and whips are quite impressive and, many activators swear by them. Not only do they work well in mobile situations, but they can also be quickly set up on a tripod in the field and many models can take a full 100+ watts of power.
If an activator is pumping 50-100 watts into a small, resonant mobile antenna, their signal is getting out there. But since their antenna might not actually have a lot of gain or efficiency on 40 or 60 meters, it can’t compete–in terms of reception–with a large aperture wire antenna.
In this scenario, the activator might be logging a load of stations, but they may not be able to hear your signal if it’s weaker than the others in the pile-up.
QRM on the other end
This is a big one, actually, and affects both park and, especially, summit activations.
Sometimes the other activator’s site is plagued with QRM (radio interference) emanating from power lines, nearby buildings, transmission equipment, and other electronic sources.
That QRM will not typically affect their transmitted signal, but it will have a dramatic impact on what they can receive andhear.
For example, I recently attempted to activate a game land I’d never been to before. On Google Maps satellite view, the site looked pretty darn remote and there were no buildings in sight. When I arrived on site, I set up my station, spotted myself, and started calling CQ POTA.
When I turned up the volume on the radio, it hit me that my noise level was a solid S8-S9! Turns out, there was a nearby power line that was spewing broadband noise across the entire HF spectrum. It was pretty much inescapable–there were no unaffected HF bands.
Had I really wanted to continue with that activation (I did not) I would have only been able to work stations with signals that were above my high noise floor. Perhaps one in five contacts at best. My chasers would have all been been left scratching their heads.
QRM isn’t always S8, but even an S5 or S6 noise level might wipe out 40-50% of the signals the activator can hear.
While hitting the field is usually the best way to escape QRM, there are spots that are as noisy an an urban neighborhood.
QSB
This is a big one; especially with the unsettled conditions we’ve had over the past couple of years. QSB, or signal fading, can be a proper obstacle in completing a contact.
If you’ve been watching my activation videos, you’ve no doubt seen chasers that call me with a 599 signal and when I respond to them, I hear nothing but silence. In those situations, I’ll repeat my reply with their callsign and signal report a few times in a row. I do this because QSB is a bit like having a three year old playing with your volume control while you’re on the air.
Seriously, imagine that three year old turning up the volume, then turning it back down, then turning it up again, and so on. It essentially has the same effect. Sometimes QSB is shallow and slow, other times it’s deep and fast–or it can be any variation in between (including deep and slow which is the worst).
In those situations as an activator, I reply a few times in a row with hopes to catch the QSB on the upswing so I can have a window of contact with the other station. When I do make contact, I try to keep the contact as short as possible so there’s hope for a complete exchange.
As a hunter, you have less control because your only hope is that QSB will be at the peak of signal strength when you call the activator.
Environmental distractions
If you’ve been doing park and summit activations for very long, you’ve no doubt experienced some “environmental distractions” during an activation.
I’ve been at parks before when the grounds crew were blowing leaves, mowing, and using other lawn equipment. It can be proper audio QRM especially if you don’t have an option to wear headphones to isolate those noises.
Sometimes the wind can cause a lot of extra noise. I’ve also been in shelters where the rain hitting the tin roof (while somewhat soothing) adds a lot of extra noise.
I’ve also been on summits and in parks where other hikers and passersby start asking questions while I’m in the middle of handling CW contacts.
They don’t understand that you’re actually in the middle of an exchange and need your attention focused. 🙂 For so many of them, it’s the first time they’ve ever seen/heard someone operating Morse Code and they’ve loads of questions. I hate to pass up an opportunity to promote amateur radio, so I’ll often pause the activation to talk with them.
In summary
If you know your radio equipment is functioning as it should but you can’t seem to grab the attention of an activator, keep in mind that it’s likely them, not you.
They’re not ignoring you, they simply can’t hear you.
The best practice for eventually making contact is to be patient and persistent. If you’re an activator trying to work another activator for a P2P or S2S (Summit To Summit) contact, keep sending P2P or S2S with your call. Often, other hunters will hear you and point out to the activator during their own exchange that there’s a weak P2P or S2S operator calling. More often than not, that’s your ticket to busting through!
Did I miss something? Please comment and share your thoughts and tips!
Thanks for all the interesting videos. I have a Icom IC-705 with the Peovi frame/handles and I found a clear plastic box that makes a perfect friction fit with the Peovi for a protective front cover. Thought I would pass on the info as I know people are on a quest for such a thing.
I’ve included a few photos. Thanks again for all the videos.

Thank you for the tip, Joe! There are a lot of IC-705 Peovi cage owners out there, so this will come in very handy!
Due to how The Container Store organizes their online store, it can be difficult to find the exact product, even using the SKU number in the search. Here’s a link to the product page for the family of containers. Simple scroll down until you find this listing (click image to enlarge):
This will allow you to add it to your cart and purchase. The price is $9.99 US.
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.
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.
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!
For those of us really, really new CW operators and aspiring QRPers, can you do a video (or a walk n talk) showing several POTA QSO’s in slow motion?
Love your work, thanks. 73 -mike ko4rit
Mike, your timing was impeccable. I noticed your message on my phone as I was preparing a park activation at Lake Norman State Park on August 9, 2021.
I decided to take a few moments prior to the activation and dissect a “typical” POTA CW exchange on my notepad with the camera rolling.
As I mention in the video, there is no standard or “POTA ordained” exchange, however, once you get into CW you’ll notice that most follow a common formula. POTA, SOTA, and WWFF CW exchanges are, in fact, very formulaic.
I believe in exchanging all of the important details–callsign, signal report and sometimes a state, province, or park number–along with a little common courtesy. You don’t want to make the exchange too long, but these aren’t contest situations either, so it’s okay to go off script a bit sometimes, too. Just remember that there are (hopefully!) others in-line waiting to work your station when you finish your exchange in progress.
Video
Note that this video is impromptu, unscripted and unedited. I’m sure I missed a few details and it’s perfectly fine, dear readers, to leave other best practices below in the comments section.
I saw your recent video post of an activation using the IC-705 and I thought you might appreciate one of my recent related projects. Earlier this year I purchased an Icom IC-705 and because I planned to carry it backpacking for Parks and Summits on the Air, I knew I needed some type of physical protection for it since it would be knocked around a bit on rocks and rough surfaces and during transport. The only cases I could find did not fit my vision; they were either too expensive or too flimsy. So I decided to fabricate my own.
I purchased a 9″ x 18″ sheet of 1/8”, 5052 aluminum. I bent it (with LOTS of effort) in two places which created a “U” channel. The lengths were 4.5″ x 3.5″ x 4.5″. I then cut off the excess and used it to make the side pieces. I then did some research on aluminum brazing which led me to purchase some “AlumiWeld Rods” from Harbor Freight and a canister of MAP gas. I then cut the pieces for the front and sides and brazed them in. You may notice the amateur looking joints on the sides of the armor.
I also wanted to have a mic and key port on the front of the enclosure so as not to be continuously connecting and disconnecting those items directly from the radio and for convenience.
The entire assembly was planned to fit perfectly in the plastic orange ammo box also shown. It is made by a company called Sheffield which is in the U.S.
The radio mounts in the armor via the AMPS pattern screw holes on the bottom. I believe they are 4mm screws… not supplied by Icom. The radio is also electrically connected to the armor via the four screws as well as the shields of the mic and keyer ports.
I recently added the vent holes on the top panel for a less than obvious reason. Although they do serve a dual purpose, my primary reason for adding them was to avoid blocking its GPS reception, but factors of cooling and weight reduction do apply.
73 de Dan (KQ8Q)
This is an absolutely brilliant project, Dan, and to my eye, there’s nothing amateur about it. The coating looks fantastic and I like all of the effort you put into stand-off space to protect the rig and connections. Mounted in that orange box, I think you’ve got an all-weather solution.
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
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.
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
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.
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
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!
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.
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.
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.
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.
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.
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.
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
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
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
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
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
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?
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.
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).
I admit it! I’m in love with BHI Ltd.’s DSP noise reduction accessories. I’ve owned most of their popular models like the DSP Desktop Speaker, and have installed BHI low-level audio modules in six different receivers and transceivers.
How is it that an audio-based DSP noise reduction accessory can be so effective? Only BHI knows, but they clearly have top-notch algorithms that rival the best of noise reduction circuits in contemporary Yaesu transceivers. (Personal bias alert: I find Yaesu’s approach to noise reduction (“DNR” in Yaesu-speak) to be quite superior to ICOM’s, and this is what got me thinking about improving the transceiver with an internal BHI NEDSP1901-KBD module in the first place.)
The noise reduction feature in the IC-705 and its IC-7300 base station counterpart is merely “OK” in my opinion, but the addition of BHI’s NR makes a significant difference in S/N and intelligibility of signals. It’s simple enough to use an external BHI product and connect it to your rig’s speaker or headphone’s audio path, but it adds wiring and complexity. The ICOM IC-705 modification described in this article is a neat, clean, internal solution needing no external wiring or power supply.
