A Useless Appendage
That's what UHF/VHF is in a QRP rig. Useless. It's a marketing gimmick.
"Icom, why didn't you build a tuner into the IC-705?" Icom: "Hey look, it's got UHF & VHF!"
"Yaesu, why didn't you design your new FTX-1F field radio so it gets an IP rating?" Yaesu: "Hey look, it's got UHF & VHF!"
Building UHF & VHF bands into their QRP rig offerings reflects laziness on the part of the product design teams. Why? Because it gives the design teams the excuse to not get other, more important things right. Like an integrated tuner, like an IP rating for water resistance, like better RF shielding, like more power output, like a better form factor.
I don't care a damn about 70 centimeter or 2 meter capabilities in a QRP radio. If I want to talk on those bands at low power I've got HTs that do a much better job. If I want more UHF/VHF 'oomph' I've got a selection of 50 watt mobile rigs that do a better job. And it's not just me. Over the past few weeks I've talked to a number of IC-705 owners, and they all report that, other than using it to occasionally hit local repeaters, they never use the UHF/VHF side of their radios.
Like I said, it's a gimmick.
It looks like Yaesu is about to release a radio that, in form and function, is little more than an IC-705 clone. Icom got lazy with the design of the IC-705, and Yaesu is doubling down on laziness by copying the 705's capabilities, and little else. The FTX-1F's packaging may be a bit more clever, but at the end of the day it really won't do anything that the IC-705 already does.
"Let's just throw in the guts of an HT, toss it over to marketing and call it a day" |
Think of what could have been. A highly refined HF-only portable field communications package that offers real performance under all conditions, and puts out enough wattage to make a difference. Yaesu is aiming at the wrong target with the FTX-1F. They're aiming at the IC-705. Instead they should have been aiming at the Elecraft KX2, and taken the opportunity to define a whole new class of radio.
Yeah I'm pissed. I'm almost 68, and it looks like I'll be dead before either of these two companies get it right.

I Don't Care How Good Your Receiver Is
With Yaesu's recent announcement of their new FTX-1F QRP radio, lots of wish-casters are commenting about how this new radio just has to come out with top-of-the-heap receiver ratings. Otherwise the radio is a complete failure. Hmmm... Now, odds are this radio will exhibit excellent receiver performance; Yaesu long ago figured out how to make great communications receivers. But if that's what you are focusing on, you are focusing on the wrong thing.
Most of the major radio manufacturers - Yaesu, Icom, Kenwood, Elecraft, Flex, and others - know how to make radios with great receivers. Right now Yaesu, Flex, Icom and Elecraft are duking it out for top position on the Sherwood Engineering receiver ratings, and Yaesu has a surprising number of rigs in the top six slots. I think it's safe to say that the FTX-1F will have a pretty good receiver.
What Yaesu (and Icom) don't seem to understand are the requirements for a low power field radio - a rugged, battery powered radio that is easy to pack and carry long distances and is highly integrated - built-in sound card interface, wireless connectivity, tuner, modern power management - and provides transmit output beyond the conventionally defined QRP levels. But as far as receiver performance, that's not the most important thing. For a radio that's marketed as a low power field radio, receiver performance is less important than form factor, user interface, non-RF features, ruggedness and TX output. Here's a few examples:
- Yaesu's own FT-817 was never a top-notch receiver. In fact, among it's peers when it was first introduced in 2004, it was just middle-of-the-pack. But the radio became a phenomenon mainly because Yaesu nailed the non-RF features and form factor right out of the gate. Users were fine with merely OK receiver performance because the rest of the little rig was outstanding. It didn't just 'fit the QRP mission', it defined the mission, and it stayed in production for almost 20 years. It was that good
- Elecraft's KX2 took the FT-817 example up a bunch of notches - improved receiver performance, an easy to view front panel, excellent internal battery performance, and an internal tuner that is truly world-class. The KX2 is still the only all-mode HF radio you can slip into the cargo pocket of your trousers and take to the field and effectively communicate for hours at a time. You can even use it as an HF walke-talkie. The KX2's receiver performance isn't first class, according to Sherwood (though it' is still very good), but Elecraft understood the QRP field radio requirements and nailed the features and form factor right out of the gate. That's why, eight years after its introduction, there's still a waiting list for newly manufactured units
- Icom IC-705 is a high quality radio that packs a bewildering variety of features and capabilities into a small package, and it ranks higher on the Sherwood receiver test results than the KX2. Yet the IC-705's design reflects a lot of compromises that make it a less capable field radio than the KX2. Why? Because Elecraft paid more attention to the QRP field radio requirements than Icom did. All Icom wanted to do was get a QRP radio, any QRP radio, to market. They squished down the IC-7300 and tossed in a bit of ID-51. Although they did a great job of integrating all the technology, the resulting form factor is a chunky and awkward box that doesn't sit well at any useful angle, lacks an internal tuner, only offers one antenna connection (no separate HF / VHF & UHF connectors) and the stock battery performance is a bit anemic. This means the IC-705 field footprint will grow - an external battery, an external tuner, a transverter so you can run HF and VHF/UHF without antenna switching, and some sort of stand to hold the radio at a useful angle. When you lay it all out on the picnic table at your POTA location and ponder the footprint, you end up asking yourself why you didn't just bring your IC-7300. Again, Icom didn't understand or ignored the QRP field radio requirements when designing the 705

What To Do With An Old FT-818?
- Put together a radio 'bug-out' kit with the FT-818 as a centerpiece and just leave it in my truck
- Set it up in my ham shack as a back-up (to a back-up). The little rig does just dandy on VHF/UHF and with my exterior antenna I can hit our local repeater with ease. I may just designate it as an over-sized HT and call it a day
- Hook it up to a SignaLink, park it on a single digital frequency, and turn it into something like a full-time JS8Call machine
- Try to rig up some sort of manpack HF system
- Sell it to help fund the possible purchase of an FTX-1F
- Use it as a door stop

Look To The Sky
So, does anyone have a clear picture on what the root cause was with yesterday's cyber outage? Was it a bad update released by Microsoft, or was it a bad update developed by CrowdStrike to be applied specifically to their own Windows applications? The on-line 'experts' are real foggy on this. One thing's for sure - the lawyers are racking and stacking.
Oops... |
Whatever the cause, this was certainly a lesson in vulnerability and fragility. Nothing nefarious or criminal, just a few lines of 'bad' code applied during an update that shuts down the airline and banking industries (to name just two) around the globe. No explosions, no gunfire, no evil hackers sitting in a star chamber somewhere in China. Just a few lines of code, code that had probably been tested and approved on development servers before being deployed to production servers world-wide.
- Reliable AC power to run things like refrigerators, home medical devices, security systems, to charge phones, computers, and power networking systems, etc.
- Reliable phone service (cell or landline) to keep in touch with vulnerable family & friends and to issue 'safe & well' updates
- Access to banking services, either on-line or at a local physical bank. Can you get to your money when you need it? (Although inflation chews away at it, experts recommend keeping a cash reserve on-hand to pay for things like food & fuel)
- Internet. The internet is what ties most of what we need together. It is the backbone that powers the global economy, and it's what links you to things like local emergency services, your loved ones (via email, text and voice comms), and necessary commercial services. Just because the internet is out at your location doesn't mean it's out everywhere. The key is being able to reach beyond your internet provider's local or regional infrastructure to get to where the internet is working
- Garmin in-Reach. Perhaps the most basic 'overhead' emergency communications system. It's a text messaging and alert system that is satellite based. Depending on the device you select (all made by Garmin) you can send and receive texts, send emergency signals (SOS), allow loved ones and emergency responders to track your location, and more. The in-Reach system has been in use for several decades now and has proven very reliable
- Satellite Phones. More expensive than in-Reach, but the overall costs have come down quite a bit over the past decade. There are a large number of sat phone manufacturers and a wide number of service providers, but they all seem to provide the same features and functions.
- Satellite based internet. The big dog in this market space today is Elon Musk's Starlink. Starlink provides amazing performance, particularly when you consider service costs. It's not cheap like home internet (you have to factor in the hardware costs), but when you consider that it's an almost completely off-grid system (you still need AC to power the router and antenna) with high reliability and performance, for me it's a must-have.
- Winlink. Winlink is really the only viable ham radio-based system that can link you with non-ham radio individuals or agencies. It allows you to send emails to anyone, anywhere, via ham radio. No license needed on their end. And it's a two-way system; email your family members regarding your status, and they can respond back using their own email provider (GMail, Outlook, etc.). While not interactive like a phone call or text message, it is still a very viable, reliable and well tested system. But to use it you need your General-class license and the right equipment, and practice, practice, practice.

NUCing Around
It's time for a computer switch-out. I needed to take one computer out of service, and that had a cascading effect. I found myself in need of a new computer that is well endowed with USB-B & C ports. Normally I'd tackle this job with a laptop and a USB port extender, but this time I decided to try something new. The concept of what Intel calls the Next Unit of Computing, or NUC, has interested me for quite a while. A NUC is essentially a mini-desktop computer. How mini? Many are small enough to be mounted directly to the rear of a stand-alone monitor. Intel didn't invent the form factor. I believe Apple was there first with their Mini Mac line, but Intel established the form factor in the Windows world. The best way to describe a NUC is that it's a laptop computer, but without the screen, keyboard, trackpad or battery - a single board computer in a small rectangular box that offers lots of ports. You bring your own monitor, keyboard and mouse to the game. A NUC is roughly 5" x 5" x 1.5", small enough to disappear on a ham shack desk, which is precisely what I was looking for.
Interior of a NUC - a board, some memory, a cooling fan, lots of ports, and that's it! |

Field Fixes
I love operating radios in the field. It's fun, and it gets my old arse out of the shack in into the sunlight (insert vampire jokes here). I love testing various radio/antenna/feedline/power source combinations out in the wild. It's challenging, builds confidence and expertise and, like I said, it's a ton of fun.
If you spend any time in the field with radios and all the associated accessories at some point you'll need to fix or modify something. Cut and strip wire, tighten screws, crimp connectors, scrape corrosion, cut string & cord, and much more. You'll need a tool kit, but a kit that is appropriate to the situation.
Not this -
More like this -
A bit of a confession. I love radios, but I really love knives and cutting tools. I've been fascinated by knives since I was a young Cub Scout (I'm 67, so do the math). I have a very extensive collection of both custom and production blades, and for years I wrote about knives and related issues on my A Fine Blade blog. So consider this post a mash-up of radios, blades and tools.
Most of the repairs and modifications we might need to do on a short POTA or SOTA deployment are pretty lightweight, and that's what I'll focus on here. You need a light and easy to carry tool kit that can handle the most likely issues that may pop up. Again, cutting and stripping wire, cutting string & cord, crimping connectors, etc. You may also need to make light repairs to your gear - tightening screws, fixing knobs, moving board jumpers, that sort of stuff. For a short field excursion all the tools you need should fit in your trouser pockets, or on your belt.
We are blessed to live in the Golden Age of Pocket Tools, so putting together that small field tool kit is both easy and fun! The grandpappy of pocket tool kits - they've been doing it for over 100 years - is Victorinox, the Swiss Army Knife folks. They make pocket knives that sport an amazing array of useful tools, things like scissors, screwdrivers, saws, pliers, awls, cork screws, tweezers, and more. I've been buying, using, and losing Victorinox knives for over 45 years, and the level of quality they bring to a mass produced pocket toolkit is amazing. The fit and finish is beyond what few other manufacturers can bring to the market anywhere near the price point of a Victorinox knife. If a Victorinox pocket knife has a drawback it's that they are somewhat lightweight and not suited to heavier twisting or prying tasks. So don't buy one and expect to be able to disassemble your F-150 with it. But for the myriad of minor tasks you will be faced with on a short deployment, the Swiss Army Knife is ideal. But which one? Victorinox makes several dozen versions of their knives - there is no single 'Swiss army knife' - the name denotes a market niche, not a single design. Here's my list of minimum feature requirements:
- Scissors
- Phillips screwdriver
- Flat tip screwdriver
- Corkscrew*
- Magnifying glass
- Awl
- Package carrying hook (surprisingly useful for twisting lengths of wire together)
The one Victorinox model I recommend that has all of what I need out of a knife is the Explorer. It hits the sweet spot in terms of features. Everything I need, nothing I don't.
Victorinox Explorer |
And yet, a Swiss Army Knife can't do it all. You will still need an effective set of pliers, wire cutters, a file and a more robust cutting blade. This is where the second part of your field tool kit comes in. You'll need a multi-tool, like one of those made by Leatherman, Gerber, SOG or even Victorinox. I've owned multi-tools made by each of these manufacturers, and all are very good, but the industry standard is the Leatherman, so that's what I'll focus on for this discussion.
- Heavy duty needle nose pliers
- Wire cutter
- File
- Saw
- Ruler
Leatherman Rebar |
While there is some overlap in capabilities between the Victorinox Explorer and the Leatherman Rebar, they compliment each other very well. With both of these tools in your POTA bag you'll be well set to handle any repair issues that pop up.
The fun in all of this, though, is that there are literally dozens and dozens of possible brands and models you can choose from. Putting together your own portable tool kit means picking from a broad array of options from a long list of models and manufacturers. What better way to waste a Saturday night, eh?
So what is your field tool package? I'd love to hear what other hams take with them when heading out for a day of field operations. What do you toss into your POTA or SOTA bag to handle the unexpected but all too common repair tasks that pop up? Let us know!

Something Pithy This Way Comes*
- Icom. They've teased out that something is coming in their advertising pages in the last two QSTs editions. Please God, not another UHF/VHF rig. Let's get serious about replacing the IC-7100. The market is there and it's ready to spend the money
- Yaesu. Yaesu's been dead silent on anything new. But they can't clam up forever. When they killed of the FT-818 last year they abandoned a market segment they once owned. There's a big gap ready to be filled with an FT-857-like replacement (and that ain't the current FT-891)
- Kenwood. Kenwood recently released their TH-D75 handheld, but there have been rumors of them coming back with an updated HF rig. There's no firm details, just whispers that 'Kenwood is coming back'. I think the best we can hope for at Dayton is an information sheet at their booth
- Xeigu. Xeigu and Radioddity have been dribbling out information on their new X6200 for several months now. I think it's reasonable to expect a Xeigu vendor to have a working model on display
- FlexRadio. I don't follow Flex too closely, so I'm not sure just what is coming. My real interest is in the HF digital work Flex is doing for the US Air Force. With this new product, we may see some of that development work trickling down to the Amateur market
- Alinco. Who's that? OK, they'll have a booth at Hamvention. I don't think they'll have anything new to announce. A quick scan of their website leads me to think they've pretty much given up on the HF market
- Elecraft. Elecraft released their handheld KH1 last year, and those sales are going gangbusters. I don't expect them to be announcing anything new
- Lab599. Russia-based Lab599 has been putting out info on their new TX-500MP manpack HF rig for several months now, but there's no confirmed release date. I would hope there's a pre-production sample on display at the HRO booth (Lab599's US distributor). This radio is much less vaporware than other teased radios listed above. Lab599 actually talks with several ham radio influencers (like Julian, OH8STN at Off-Grid Ham Radio) and responds to questions about the radio. That's a good omen
- HF Communications Corp. This India-based company makes what looks like some really neat HF radio kits that are very reasonably priced. Most of what they offer are Raspberry Pi-driven SDRs, so they are, in the words of the company, 'hackable, tinkerable, scriptable'. Their top-of-the-line rig, the sBitx v3 is only $429, fully assembled and delivered in the US
- Codan. Speaking of manpack radios - NVIS Communications, the US agent for Codan, will be at the show. Codan is an Australian-based manufacturer of commercial and military HF rigs, and their products are very highly regarded and in wide use in the Asian, Indian sub-continent and African markets. A lot of MARS and SHARES members have purchased Codan product through NVIS and they've developed a bit of a following. What's interesting regarding Codan's showing is partly about who's NOT at Hamvention - Codan's leading competitors in the market: Barrett Communications (recently purchased by Motorola) and Harris. I believe this reflects NVIS Communications' support of the MARS and SHARES markets and their interest in developing a foothold in the Amateur radio space. I'm particularly interested in their H 6110 manpack radio
- HobbyPCB. I've built two of HobbyPCBs HardRock50 amps for my QRP rigs, and Jim Veatch at HobbyPCB recently released a 100 watt upgrade kit for the amp. I'd want to talk with Jim about the level of difficulty for the upgrade. I'm fine right now with 50 watts for my IC-705 and KX2, but 100 watts is 'more better'

Old Radios and Misplaced Nostalgia?
There's a style of radio that has fascinated me for decades. I love the concept of the manpack VHF and HF rigs, a design we first saw in WWII as the SCR-300, reached a design peak in the 1960s with the PRC-77, and culminates today in radios like the Harris PRC-160 HF/VHF manpack
SCR-300 in use during WWII |
AN/PRC-25/77 as used in Vietnam |
Current production Harris PRC-160. Twenty thousand dollars of glorious battle-ready manpack radio technology. And you can't have one. |
For years I've idealized this style of radio, and pursued US and foreign models on the used market. But why a manpack? They really don't perform any better than table-top models. In fact, in the Amateur Radio realm they are more likely to perform worse - low TX power, poorer receiver performance, cooling issues, no internal tuner, too many accessory cables, and more. I look beyond all that to the unique and fascinating mash-up of technologies that are used in successful military and commercial manpack designs, designs that can overcome many of the limitations I've listed and provide good mid-range TX performance, good receiver performance, robust tuners, robust weatherproofing and long battery life. All in a package small and light enough to toss in a backpack, go for a walk, and make contacts.
From Elecraft's own website. This KX2 was designed with handheld HF operations in mind |
The KX2 isn't particularly rugged, and it's very vulnerable to water intrusion (the case is just a stamped metal box with lots of openings), but the performance is world class.
There may be some interesting developments in the manpack HF field just on the horizon. One effort that is beyond the vaporware stage is the Lab599 TX-500MP. This was teased out earlier last year, and one or two pre-production models have seen daylight. Lab599 is a Russian company, but it moved quickly to distance itself from Putin and his antics in Ukraine. The company moved its production to the UAE and seems to have found some stability. The TX-500 has developed something of a cult following, and the company responds well to input and puts out regular firmware updates, always a positive sign.
There's not a whole lot of info out on the TX-500MP yet other than some basic specs, but Lab599 does keep the user community updated on its development status. The radio looks like a channelized version of the TX-500 with an integrated battery pack and antenna tuner. There has even been talk of a digital soundcard interface. In terms of a real product that may see the light of day in the next year or so, this looks like the best bet.

Yesterday word came out that Martin F. Jue, the president and founder of MFJ Enterprises, has decided to shutter MFJ and all of it's associated brands, and retire:

MARS Modding the IC-705
Yesterday I decided it was time to do the MARS mod - wide-band HF transmit modification - to my IC-705. There was nothing special about yesterday, other than the fact that I finally screwed up the courage to open up the little radio and git 'er done!
I like to do the MARS mod on as many of my HF radios as possible. I'm a MARS and SHARES operator, and doing the mod gives me the knowledge that I can use this very expensive and capable radio outside of the ham bands. I've done MARS mods on the IC-7100, 7200 and 7300, Yaesu FT-891, the 991 and the Elecraft KX2. The process differs from manufacturer to manufacturer. Icom's process is the most destructive - you have to carefully remove very small diode(s) from one of the boards in the radio. Yaesu's is the least destructive - you create a solder bridge across one or more open pads on one of the boards. Elecraft's is the most elegant - you simply do a firmware update.
There are several good on-line resources for IC-705 mod. Of course you won't find anything official from Icom on the subject, but it doesn't take long for the info for any radio, from any reputable manufacturer, leak out. So it was with the IC-705. Within a few months of release, word was already circulating on how to do the modification.
Before going further, I need to say this - if you want a MARS modified radio your best and safest bet is to buy a new one from the major distributors like HRO or GigaParts. They are authorized by the manufacturers to do the mods, have all the technical data, equipment and experienced personnel to do the job, and your radio retains the original manufacturers warranty. Yes, you'll pay extra, but it is the safest route to take if you want a new ham radio with this modification. I only do this mod on radios that are out of warranty, and I do it only on radios I own - I don't do this as a service for others.
OK, back to the resources. There are several videos on YouTube showing how to do the mod. All follow the same steps, but in each the mod is done with varying levels of expertise. In one or two I'm surprised the radio survived the surgery. The best video I've found, and the one I watched several times before doing my mod, is the one put together by TRX Lab:
There are also modification instruction sheets posted to the mods.dk website. Mods.dk is a paid subscription website, but they do allow the download of one document per day to those who are not paid members. If you go there, look for the document dated 26 March 2023.
The mod involves removing one very, very small surface mount diode from a portion of the main board that is very crowded. This implies finesse, and the right tools. Of course you'll need heat. Most use a soldering iron. However, I've invested in a quality hot air station specifically designed for electronics use. The model I bought is the Quick 861DW. The Quick is considered a basic 'pro' unit, but it gets generally excellent reviews from people I trust. Honestly, I don't even look at my soldering iron when doing this kind of work. The hot air station is a much better tool.
All the other tools are pretty run-of-the-mill for electronics hobbyists:
- screwdrivers (I use JIS standard screwdrivers when working on Japanese manufactured gear)
- forceps and tweezers
- heat resistant tape (for masking components on the board)
- static-safe prying and opening tools (commonly called spudgers)
- wrist grounding strap
- static free work surface
Here are the two black and gray antenna wires on the main board that have to be removed before the main board can be taken out and flipped over. One is the HF connection, the other is the VHF/UHF connection. Not sure which is which.
Gone, gone, gone... |
The radio is a very neat, trim and compact design on the inside. Hey, it's an Icom, right? It's also a very rugged build; everything inside the case is very well secured - literally screwed down tight. There's no wasted space and nothing is flopping around in there. It's a brick. Honestly, with everything so tightly packed in and with no airflow it's a wonder these radios run as cool as they do.
24 March 2024
The Acceptance Phase
Over the years I've posted here a few times about my adventures with my Elecraft KX2. Recently I wrote about upgrading it with the new Elecraft KXIBC2 board, which allows charging of the lithium-ion battery while still installed in the radio. I've also sung its praises here and on other forms for it's excellent design, modularity, maintainability, manufacturer support and world-class performance on SSB.
What I've had to finally come to accept, though, is that the KX2's is a lousy digital mode performer.
I so desperately want this little rig to run things like Winlink and JS8CALL, but I've struggled on-and-off for two years to get it working correctly, with no real success. Lord knows, I've put a few dozen hours into the effort, and have bought no end of USB sound card dongles, Digirig interfaces, cables and assorted bits 'n bobs. All to no end. My last attempt was a few days ago, when a JS8CALL session on three different bands netted only two very weak beacon reports. OK, I was getting out, but not well, and I have no idea why.
I'm no digital mode dummy. The list of radios I've run Winlink, JS8CALL, VarAC, Fldigi, MS-DMT and other digital modes on is extensive. Probably close to a dozen different models across all manufacturers, some with internal sound card interfaces, some requiring external sound card setups like the Signalink. The KX2 is, hands down, the most difficult radio I've ever dealt with on digital modes.
"No Winlink for you!" |
This isn't a tragedy, merely an inconvenience. I've got other QRP rigs that do just fine on digital modes, like the Icom IC-705. It's just disappointing that an otherwise great little rig is a stinker on digital. Going forward it'll be relegated to SSB only, and in that use it's at the top of the heap. It's such a cracking good little radio that it'll stay on my 'do not sell' list, along with my Yaesu FT-818 (which, by the way, runs digital modes without breaking a sweat). One of the reasons is that the KX2 has had the MARS mod done to it, and I've actually used it to check into both MARS and SHARES nets. It's usefulness as a sideband rig is beyond measure.
So if anyone out there has a KX2 (or KX3) and runs it successfully on digital modes, I'd desperately love to talk with you. Drop me a line.
Until then, I'm screwing up the courage to do the MARS mod on my IC-705.

Thinking Outside The Box
Pet peeve time.
Ham radio is in love with the go-box. You can't attend a hamfest or club meeting without seeing presentations on, or hearing discussions about, go-boxes; what goes in them, how they are built, how to power them, how to connect to them, etc. Suffice to say, ham radio is go-box batty. Proof? Just Google 'ham radio go box'.
The go-box concept is good, but it can be limiting in both capabilities and scope. Just the mindset that all your capability has to fit into a single box, and if it doesn't fit, then you don't need it, is a silly way to approach a problem.
I haven't seen too many go-boxes that were built to meet a specific mission or requirement. For example, I once asked a person demonstrating his go-box why he included a VHF packet modem. He admitted there wasn't a clear need for it - it was there 'just in case'. This in a region that hasn't seen any public service related packet activity for over 15 years.
I don't want to disparage the concept of the go-box, but the 'box' mentality and the lack of a requirements-based approach seems to lead to a lot of implementations that look like solutions in search of a problem.
Let's think beyond the go-box and instead think about the concept of a mission-focused communications hub or, as we used to call them in the Army, a 'comms center'. A comms center is just a place - a table, a room, a shelter, a tent. Heck, it can be the tailgate of a pickup truck. But it is the place at which you build out a communications hub in support of an event or incident, and build it out tailored to the mission requirements.
I use the term 'mission focus' a lot, and it really is the key to the comms center concept. You build capability to meet a specified mission. Let's use a county-level ARES group as an example. Do a mission analysis and ask yourself (and your EMA) these questions:
- What are your served agencies?
- What are the missions of these served agencies?
- What communications capabilities do they need to meet their missions?
- What are their organic communications capabilities?
- What are they lacking?
The comms center concept is also fluid. In the Army, I've been in situations where the comms center started out as just a single VHF radio mounted in a truck, a map board and a message log. Over time it morphed into a dedicated shelter with multi-channel voice and digital HF and VHF capabilities, a landline switchboard and a SATCOM link. What all this gear wasn't, was stuffed into a single box. That was impractical and unwieldly; each communications system required more elbow room than a boxed enclosure could offer.
Far-fetched for a civilian operation? Not at all. With growing reliance on systems like Winlink and other HF-based digital tools like JS8CALL, Fldigi, VarAC, and use of internet-linked VHF voice and data modes like DSTAR, C4FM, DMR and Echolink, the technology stack in a civilian comms center can easily match that found in military units. And let's not forget the vulnerability of terrestrial-based internet. There's a reason a Starlink package is a standard part of many civilian communications centers.
But a comms center isn't really about comms equipment. The job of the comms center is moving information, and the synchronization of communications across systems, agencies and departments. With this in mind, a comms center's key functions include:
- Establishing and maintaining communications support as directed by the event director, incident commander or incident communications leader
- Maintaining the event/incident radio log
- Conducting an overall 'radio watch'; ensuring all comms systems are up, operating and proactively monitored
- Interfacing communications systems. For example, establishing radio-wire interfaces, making sure information received via radio is 'hopped' to the appropriate systems like WebEOC, internal chat systems, status boards, etc.
- On-boarding new personnel, departments or agencies that show up to support the incident, making sure their organic communications systems are integrated into the communications architecture
- Radio set-up and programming
- Troubleshooting communications issues

A Small KX2 Upgrade
The KXIBC2 board seen from the 'outboard' side |
Jumper wires soldered in place on the main board |
Battery pack in place, time to test. The LED on the charger board is a steady yellow, so the battery is charging and all's good! |
A quick firmware update brings everything up to snuff |
The little rig is merrily charging away, getting ready for the next radio adventure! |
There you have it. A dandy little rig made even better, courtesy of a company that actually listens to and engages with its customers.
