Testing the Ionosphere: A 100 milliwatt to 1 watt POTA Activation During a CME? Why not!?

Sometimes, I like the odd “exercise in futility.”

I enjoy shaking up routine and since POTA and SOTA activations are my routine, they end up being the shakers.

On Monday, September 18, 2023, I found out that our planet was rotating into a large CME (Coronal Mass Ejection). This CME made all of the space weather news and we planned for either some potential radio blackouts or at least very unstable conditions.

As I’ve said many times before, I never let the potential for poor propagation stop me from hitting the field. Don’t let it stop you either.

Lake Norman State Park (K-2740)

I had a full afternoon to play radio, so I made my way to Lake Norman State Park.

En route, I tried to think of a way to shake up the activation a bit. I planned to activate at the same spot I had during my last visit because I knew the park’s main trail system was still closed and, frankly, I wanted to take advantage of the EV charger at the visitor’s center again!

I’d packed MW0SAW’s End-Fed Half-Wave (the gift that keeps on giving, Steve) and I did have one new radio toy (more on that later).

I also had a lot of time–at least, more than I normally do during a POTA activation–so I thought it might be fun taking my KX2 down to the lowest power setting it has: 100 milliwatts.

I’ve activated parks with 100mw before, but never intentionally on a day when I knew propagation would be poor.

I figured with enough time, maybe I would get the ten contacts needed for a valid POTA activation.

If not, it would be fun trying!

Why Milliwatting?

At the end of the day, I think taking our radios and antennas to their low-power extremes gives us a taste of what we can actually do with so little signal.

I remember shortly after I bought my first Elecraft KX1 in 2008, I was speaking with a local ham and he told me that a maximum output of three watts was pretty useless and that I really needed a minimum of five watts if I expected to make any contacts.

Part of me did feel like perhaps I’d bought something more akin to a toy–fun to look at and hold, but not terribly practical.

Then I started using that KX1 to make contacts and even carry on extended rag chews. Turns out, three watts gets a lot done!

Today, I’ll often run my MTR-3B with three watts or even less when activating a summit and the results are simply outstanding–fabulous DX and contacts galore.

I know 100mw is a proper compromise, but I like knowing what I can achieve with so little. Tinkering with it in the field and listening to signal reports (also reading RBN stats) gives me a good idea.

In an emergency situation? If I could only push 100mw into a decent antenna, I know it wouldn’t be ideal, but I know it wouldn’t be futile either.

Begali Adventure Dual

Another activation motivation was the opportunity to test my new-to-me Begali Adventure Dual paddles. Continue reading Testing the Ionosphere: A 100 milliwatt to 1 watt POTA Activation During a CME? Why not!?

Check out US7IGN’s “PFR-5” QRP Radio!

My good friend, Wlod (US7IGN), sent me the following message recently and has kindly allowed me to share it here on QRPer:

Hi Thomas,

I was going to write to you too. I saw your posts on QRPer.com about QRP field kits and decided to share my collection of QRP radios, which I keep now. One of them is my homemade one.

I called it PFR-5 because it has 5 bands, unlike original PFR-3, which was taken as a basis.

The rest are my friends’ radios that I’m temporarily storing. Tulip/Tulipan SDR from SP3OSJ, ELECRAFT KX3, and copy of Mountain Topper and original PFR-3.

I did not compare them, because this needs to be done outside the city where there is no noise and you can evaluate their RX performance, which I cannot do now for obvious reason.

Have a good day!


73 de US7IGN!

Thant’s brilliant, Wlod! I think you may have the only PFR-5 in the world! Ha ha! I love how you marked it as the “Ukrainian Edition” and gave it that brilliant image on the front face.

Thanks for sharing with us, OM! I dream of the day you can take these radios to the field and give them a proper comparison.

Guest Post: The Full Moon, Eels, and /P Operation on Mount Peyton, NL, Canada

by Scott (VO1DR)

Introduction

I have been eyeing Mount Peyton in central Newfoundland for years as an attractive spot for /P HF operation.  Even before my radio adventure to Mount Sylvester (reported earlier in QRPer.com), I have been seeking a way to get up Mount Peyton.  Like Mount Sylvester, Mount Peyton is an inselberg of granite protruding above the glacial plain of central Newfoundland.  However, Mount Peyton is even larger and higher; an elongated ridge about 800 m long reaching up to 487 m (1,599 ft) above sea level.  For SOTA enthusiasts, it is designated VO1-CE-005, multiplier 4.

Figures 1 and 2 show the location local topography around Mount Peyton.

Figure 1 – Highway map of central Newfoundland showing Mount Peyton and landmarks
Figure 2 – 1:50,000 scale map I used during trip showing topography near Mount Peyton and our hiking route.  Each block is 1 km on a side.

Mount Peyton is a case of “so near and yet so far”.  Just west of Gander, this ridge is visible in the distance south of the Trans-Canada Highway (the main arterial highway traversing the island of Newfoundland).  However, in summer there is no trail directly to the top, and access to its base is only via rough ATV tracks and wet bogs.  One must get to the base of the mountain, then hike overland to the south side and climb a long inclined cleft in the hillside to the top.  This cleft is the surface trace of a fault in the underlying granite (see route on Figure 2).  By contrast in winter, Mount Peyton is a popular and readily accessible snowmobile destination with dozens of machines roaring up this same cleft on a thick blanket of snow.

The Full Moon and Eels

Looking at maps and Google Earth, an approach on foot would entail a three-day hiking trip.  While this sounds delightful, my current living situation would not permit this, and in addition I have no hiking buddies able and willing to make such a commitment.  So, it became clear I needed all-terrain vehicles (ATVs) to get quickly to the base, so we could do the entire trip in one long day.

I don’t own an ATV and after multiple attempts over this summer to find any ATVers interested in such an adventure, there were no takers.  Apparently ATVers like to ride, but don’t like to get off their machines ?. I finally found a local outfitter (Paul) who not only could supply ATVs, but had hiked multiple times to the top of Mount Peyton – a perfect fit.  For safety, I needed at least one extra person to go to the top.  All other potential radio or hiking companions fell by the wayside for various reasons, so it became just me and Paul.

As is common in rural Newfoundland, Paul is a Jack of all trades and is also a commercial eel fisherman.  American Eels (Anguilla rostrata) have a fascinating life history (https://en.wikipedia.org/wiki/American_eel) and inhabit freshwater rivers and streams in Newfoundland.  Paul harvests them in conical net traps anchored to the stream bottom (Figure 3).

Figure 3 – An eel trap in place in a local stream.  Eels move into the large mouth and get trapped in the bottom cage.

He told me that eels run during the new moon and stay put near the full moon.  Now doesn’t that ring deep bass notes of evolutionary biology!?  Since eel fishing is an important part of Paul’s income, we agreed to fit in my radio around his eel-catching.  He would be available around the full moon when the eels were sluggish; toward the end of September, the moon was full on the 29th.  Given the local weather, we settled on Tuesday, September 26 as our day.  Isn’t life fascinating – the moon controls eel movement, which controls human movement, which controls our /P radio expedition!

Getting There was Half the Fun

I drove from St. John’s to Paul’s cabin west of Glenwood, NL on the afternoon of Sep 25, on the beautiful shores of Indian Arm Pond (Figures 4 and 5).

Figure 4 – Paul’s cabin on Indian Arm Pond
Figure 5 – Shoreline of Indian Arm Pond

We planned an early departure on the ATVs.  Sun-up was around 7 am and sun-down was about 7 pm, so we had 12 hrs of daylight to work with.  September 26 dawned bright and clear (Figure 6) and we were soon packed and underway on two ATVs (Figure 7).  We drove for over 2 hrs on a wide range of roads, tracks, and rough trails to a point where we dropped the ATVs and started hiking (one way distance 26.7 km or 16.6 mi).

Figure 6 – Dawn over Indian Arm Pond on September 26.  Time to get moving!
Figure 7 – Scott on Polaris 450 ATV ready to go.  Black lumbar pack on right.  Blue survival bag on left.  Pole strapped on my left.  Radio and spare water in elbow compartments.
Figure 8 – Turtles are huge in Newfoundland
Figure 9 – Passing over beautiful Neyles Brook.  This is quintessential central Newfoundland scenery.
Figure 10 – Magnificent Mount Peyton looms in the distance.  This view is toward the nearly-vertical NW face.  We are about half-way there.  After dropping the ATVs, we will hike around the right end and climb up the far (SE) side.

This trip reinforced that I am not a motor sports guy.  The ATV ride was long, bone-jarring, and noisy.  Buying an ATV at great expense and doing this for “fun” is a mystery to me; and forget about seeing any wildlife.  But, hey, the ATVs got us there; we couldn’t have done this trip without them!

A Recap of the 2023 W4 SOTA Fall Campout

Another W4 SOTA Fall Campout is in the books! What amazing fun.

This year, the campout was held at Lake Rabun Beach Recreation Area in north Georgia.

Once again, Joshua (N5FY), and I shared a campsite. He arrived Wednesday afternoon and I showed up Thursday afternoon around 2:30 PM.

There was quite a lot of wet weather in the forecast, so I opted to bring my large 6 person tent (the orange one above) instead of my two person ultralight tent. My thinking was that, if need be, we could us the large vestibule on this tent as shelter while eating and cooking.

Joshua was way ahead of me, though, and brought a canopy for the picnic table.

After pitching my tent and setting up, Joshua and I discussed how we should spend the rest of the afternoon. One thought was to try to squeeze in a SOTA activation, but we would have been fighting sunset at the end of it.

Instead, Joshua suggested that we build some antennas.

It was then I noticed that Joshua’s picnic table canopy had a built-in spool of 26 gauge wire!

I shouldn’t have been surprised. Joshua is the fellow behind the Tufteln brand of antennas. Turns out, he brought along a full antenna-building station.

I built a long random wire antenna and started a 30M EFHW.

That evening, we had friends pop by the campsite, ate dinner and fit in a quick POTA activation.

We didn’t have to drive to the activation site because our campground was in the Chattahoochee-Oconee National Forest (K-4473). Continue reading A Recap of the 2023 W4 SOTA Fall Campout

Other Items as Appropriate (most items not for hikes of any great distance)

Summary

My experience from years of traveling for both pleasure and business has shown that I always overpack and take too much “stuff”, and POTA is no exception.  However, I have made an attempt to modularize my POTA gear so that I can lighten my load depending on what type of activation I have planned and how far I will be going from my parking spot.  If you will spend some time scrolling through my blog, you’ll find examples of most of the following:

If I’m going to a location where I’m planning on operating at or not too far from my truck, I’ll take everything on this list to give me maximum flexibility as to how I set up.  Probably the most extreme setup involves erecting my 12 meter Spiderbeam mast on my heavy duty towing-style bicycle rack and deploying a wire antenna as an end-fed vertical or as a sloper.

At the opposite end of the spectrum, if I’m going to be doing a pedestrian mobile (/PM) activation then all I need is my KX2 bag, my Maxpedition Gear Cocoon Pouch, probably my Sony ICD-UX570 Digital Voice Recorder (unless I can manage to log on paper somehow), and (optional) my battery bag with shoulder strap.

If I know that I’ll be doing a wire antenna activation using a tree for support then I can wear my L.L.Bean day pack, but omit the Maxpedition Beefy Pocket Organizer and the Maxpedition Gear Cocoon Pouch.  In that case I’ll likely wear my battery bag with shoulder strap.  I may put the KX2 bag in the pack or carry it by its handle.

And, if I know that I’m going to be doing an AX1/AXE1/AX2 picnic table activation then I can omit Stuff sacks #1,# 2, and #3, but otherwise wear my day pack and battery bag as described above.

Of course, there are always variations, such as using the camera tripod, AXT1, and RG174 coax to set up at a picnic table, but allow the AX1/AXE1/AX2 antenna to be more in the clear (such as operating from a picnic shelter).

I’ve also done what you might call “pedestrian stationary”, deploying the KX2 HT-style and hand-held, but sitting in my backpacking chair.  Or deploying a wire antenna (EFHW or “random”), but sitting in the backpacking chair with the rig balanced on my leg.  By traveling with “everything” but packing in a modular fashion, there are any number of variations on how I can set up for an activation.

Heli Pro Backcountry pack with portable field kit

Dugbo’s MCHF compact field kit

by Dugbo (KD7DUG)

Intro

My field radio kit is not so different or unique that it stands out from the many other experienced ham radio operators that have assembled and shared their field kits with the ham radio community. I am new in this game and by no means an expert. However, my field radio kit was designed as a fit for purpose and tailored to my CW operating needs and especially the bank account. I wanted my portable field kit to be nimble and easy to deploy at a minute’s notice. With many of the popular QRP radios backordered and even not available at this time, I chose a different route with my choice of radio.

Radio

Currently my preferred radio is the very capable SDR mcHF-QRP HF transceiver created by Chris, M0NKA. The mcHF is a smaller designed portable radio that simultaneously packs a left hook, upper hook punch, it’s a real contender. The radio is standalone, and its compact design is in comparison to other transceiver competitors with transmit and receive on 60-10 meter amateur bands with 5W output power on CW and SSB.

Currently the mcHF by M0NKA is very difficult to obtain and currently the kits are not available to purchase. However, there are multiple clones of the radio being offered by Chinese manufacturers.

Radio Equipment

Radio Equipment Kit

Priority was to protect the radio while traveling in the field. Securing the radio in a case to prevent damage from the motions of backpacking up a summit while also protecting the rig from environmental factors, dreaded dust, dirt, and water.

The Evergreen 57 waterproof dry box was a perfect match with the mcHF and additional operating equipment. The radio slides perfectly into the rubber molding of the evergreen case and prevents the radio from moving around in the case during transport.

To power the radio, I need an efficient battery for my needs. Batteries are heavy and weight was one of my concerns. Also on my mind was which battery would provide enough amp hours for an activation? To minimize the weight and provide enough power for one to two POTA|SOTA activations, I finalized my decision on a 3Ah BioEnno LIPO4 battery to supply power the mcHF. To link the battery to the radio, I am using a 5.5 x 2.1mm with an Anderson Pole connectors.

For audio I am using an Anker IPX5 speaker for GoPro sound recording along with 3.5mm Ugreen Headphone splitter for an old pair of Iphone headphones. I prefer headphones for copying incoming callsigns, RST and QTH from hunters and chasers. The headphone splitter, headphones and two additional 3.5mm connectors for speaker connection and key are packed into the rubber mesh located in the upper lid of the Evergreen case.

I am using two highly regarded and engineered portable keys. The CW morse N0SA and the BaMaKeY TP-III, are very rugged and ultra-compact twin paddle keys for CW operations.  For the BaMaKeY TP-III protection against the elements, it resides in a small waterproof case lined with foam. The N0SA paddle fits snuggly into the Evergreen case.  I use a Sea to Summit bag to carry a smaller travel case that contains the Rite in the Rain pad with pens for logging, the Anker speaker, NY4G EFHW antenna, ABR316 coaxial cable and two 10’ pieces of paracord with two tent stakes for antenna deployment.

Radio setup on Summit W6/CS-445

Once on the summit, I set up my radio equipment onto the Sea to Summit bag for additional protection from the ground. For a backup HF radio, I carry the very reliable Venus SW-3B 5W CW radio in small fly fishing Yonah Pack attached to my backpack. A perfect fit and well protected.

Antenna

I am using a NY4G 64:1 balun EFHW QRP 40,20 and 15m with additional 17 and 30m bands with a maximum of 15W on CW.

To deploy the antenna in the field in an inverted V configuration, I am using a modified 4.5m light weight expandable carbon fiber fishing pole (99g).

25-inch Valkyrie archery carbon shaft

To keep the antenna and mast vertical, I modified a 25-inch Valkyrie archery carbon shaft at one end with a 200g target tip and the other end with a center pin sleeve. No need to carry a small hammer to pound in the arrow shaft into the ground, mother nature has me covered with plenty of small size rocks in the field. I am using 15ft of ABR316 coaxial cable.

SOTA Activation W6/CS-323 EFHW antenna in an inverted V configuration
SOTA Activation W6/CS-445 EFHW antenna in an inverted V configuration

Navigation

I am using onX Off-Road GPS app on my mobile phone to download maps of selected activations. I also carry an inReach Mini Messenger satellite tracker and communicator for safe insurance. Unexpected situations can occur without warning, so I always like to be prepared than not to be.

Wrap Up

Heli Pro Backcountry pack with portable field kit

I am using a 20-year-old Dakine Heli Pro Backcountry pack to carry my compact field kit.

I used this pack for backcountry snowboarding in my early years. This pack is fantastic because of the extra compartments for carrying gear. It is also fitted with an ice axe strap that is perfect for carrying the expandable carbon fiber pole. The total weight of my portable field kit is 2.2 Kg or 4.9lbs. It might not be the lightest portable field kit setup, but it is definitely not the heaviest.

Yonahs Pack and the SW-3B

Overall, I am very satisfied with how my portable field kit came together as well as its performance in the field.

Field Radio Kit Gallery: VA7EKA’s Yaesu FT-857D Field Kit

Many thanks to Andrew (VA7EKA) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page.

You may note that this isn’t a QRP radio, but the FT-857D will run QRP power! If you would like to share your field kit with the QRPer community, read this post. Check out Andrew’s field kit below:


Yaesu FT-857D off-grid portable kit

Andrew (VA7EKA)

As part of my amateur radio operations, I’ve quickly seen the advantage of having a small, portable radio I can operate anywhere and deploy quickly. Especially as I don’t have a permanent HF antenna installation at home, being able to set up in the yard (or even indoors) in a pinch is pretty high on the list of requirements for me.

I started reading online and watching videos about this topic, and found an excellent video from KT7RUN “The Tech Prepper” (and an earlier one) which showed a super-slick portable radio setup featuring the Yaesu FT-857D. Prior to finding those videos, I had already acquired an FT-857D due to its all-band, all-mode operation and compact size, and Gaston KT7RUN’s kit seemed like a very compelling setup for this radio.

Here’s what I’ve ended up with for my off-grid-capable “grab’n’go” radio station:

Inventory

Currently this is the inventory for this kit:

Antenna options:

and for charging this station in the field…

Details

Of course, the core of this kit is the radio. It’s popular for a reason. All-band, all-mode “shack in a box” in a truly portable form factor. Capable of 100w operation, it’s more than enough to make whatever contacts you need. In my case, because the battery has a max 20A continuous-discharge specification, I wouldn’t actually transmit at a full 100w with this exact configuration. Not a problem – I’m not expecting to transmit at those levels with a pack of this size.

The pack frame is truly solid, though it adds a good amount of weight (1.364lbs with all options). It’s absolutely worth it though. Not only does it provide rigidity and protection, it also provides convenient mount points for attachments, like the relocated antenna connections and Digirig holster. I could securely attach additional items if needed.

The battery just fits into the MOLLE pouch which is pretty lucky. I got a small PowerPole distribution block so I can not only connect the radio to the battery, but also the Genasun solar charge controller and whatever other power-related accessories I might use (e.g. Dakota Lithium’s 5v USB charger which I’ve adapted to PowerPole). Solar-wise, the charge controller I went with has a little more capacity than what I’m using currently with the 75w panel. I figured I should bump up to the 10amp charge controller to allow for a larger solar panel later on.

For CW operation I’ve relocated the jack with a basic 3.5mm audio extension cable going up through the bag and looped through the PALS webbing on the High Ground Gear PRC-117G bag. For a key I’m usually packing a basic 3d-printed iambic paddle I got at a swap meet for $20. I’d love a N0SA SP4 paddle but… $$$ :‘D

In the following photos you can see how I’ve laid out the relocation cables. I specifically took photos of these to show people who want to re-create this kit, because it was pretty tedious to get it all in there. Hopefully these will save someone a bit of time. 😉

All in all, this kit weighs in at 11 pounds. It’s a bit heavy to carry for a SOTA activation, but for POTA it’s no problem at all. I have indeed carried it up to a SOTA summit, but HF propagation conditions were poor and I was really struggling to make any contacts. Ended up resorting to activating on 2m with a tape measure Yagi. 😉

Because of the PALS webbing on the PRC-117G bag, this portable kit could be strapped to a larger backpack as needed, though typically I have just carried the kit inside my backpack, to keep the weight closer to my body. Perhaps more notably, additional accessory pouches could be attached, like a pouch for logbook/pencil/antennas/CW key etc.

Conclusion

So how is this kit to actually use? In a word, awesome. Drop it on the ground or on a table, deploy and attach an antenna, turn on the power. If I’m expecting to be on air for a long time, I can attach the solar charge controller and solar panel to keep the station running (though I have yet to do this while operating, since I completed this kit very recently). I can go out into the field and use this setup indefinitely, regardless of available electrical infrastructure.

For digital operations, I have a ToughBook CF-31 which is fully configured with all relevant software I’d typically use. This is great for tossing in the vehicle for a POTA activation, and even feasible for SOTA if you’re in great shape or willing to carry the extra weight. An alternative for digital ops could be a lightweight single-board-computer, tablet, or netbook, of course.

Just for fun, here’s a map of most of the QSOs I’ve made with this rig since putting it together. It’s not exhaustive, but what I could quickly gather up for this post. 133 contacts across 11 countries. The furthest contact thus far is with VK2WN on 30m FT8, at a nice 11965km (7435mi) distance, with just 5watts of output power on my side. Nice!

If you have any questions about this kit or would like additional details, please feel free to reach out. I’d also be curious to hear from anyone who follows this build and creates their own variation!

A Trailside, Low-Impact, Knee Board POTA activation at the Carl Sandburg National Historic Site!

On Friday, September 15, 2023, my wife and I had a few hours midday to enjoy the gorgeous pre-fall weather, so we decided to go on a hike with Hazel.

My wife was the one that suggested I pick out a hike that would open the door to a short POTA activation (isn’t she the best–?).

Carl Sandburg National Historic Site (K-0804)

Earlier that week, I made a note to activate the Carl Sandburg National Historic Site in the village of Flat Rock, North Carolina. I passed this idea by my wife and she agreed that it’d make for a perfect outing.

The mission of the Carl Sandburg National Historic Site is to preserve Connemara, the home of Pulitzer Prize-winning poet and writer Carl Sandburg.

The park has a wonderful trail network and I hadn’t visited it since 2016, during the National Parks On The Air (NPOTA) ARRL event.

Technically, I could go back into my NPOTA logs and upload my Sandburg activations to the POTA site because previous activations do count, but I’m not actually motivated by my park count so much as I am just having fun working new-to-me sites under the new POTA program.

That said, my somewhat flexible, non-committal goal of having at least 100 unique parks activated for POTA before the end of 2023 was also on my mind; a small motivator to expand my POTA footprint.

Admittedly, there really aren’t many parks that are within two hours of my QTH that I haven’t already activated for POTA. The ones left, like Sandburg, are just outside the corridors I normally travel.

The Sandburg site is a beautiful one, and I think Hazel may have even remembered this spot from so many years ago. My wife and I got a kick out of how giddy she was to hit the trails, smell the smells, and meet all of the other hikers.

Hazel: “Enough talking, Dad! More hiking!”

Time to hit the trails and find an activation spot!

Knee Board Portable!

Back in 2016, I got permission from a Sandburg park ranger to place a wire in a tree in order to perform my NPOTA activation. She only asked that I perform my activation on the trail network (not at the house and goat farm).

Wow…I just checked and I had forgotten that I made a short field report of that activation over on (my other blog) the SWLing Postcheck it out here.  Back then, my KX2 was still very new and shiny!

Not even a scratch on the KX2 back then! Today, Hedy looks a little more field battered! 🙂

And here we are seven years later and I’m still activating the Carl Sandburg site from my lap. This time, however, I don’t have my radio on a clip board, I’m using a folding knee board:

This is my Tufteln/N0RNM folding knee board and you’ve seen me use it in numerous activation videos.

Instead of just placing my logs and radio on the knee board, like I did back in 2016, I wanted to place my entire antenna system on it, too.

You see, although I’m sure the staff at the Sandburg home wouldn’t mind me putting a wire in their trees along the hiking trail, I couldn’t find a staff member to ask, so I used this as an excuse to try something I’ve always wanted to do: mount my AX1 on the knee board as well!

We found a park bench a mile up the trail and decided to set up there. Continue reading A Trailside, Low-Impact, Knee Board POTA activation at the Carl Sandburg National Historic Site!

W2AEW Field Radio Kit

I’ve only been active with POTA for a little over a year, but have put together a kit that gives me lots of options for antenna deployments.

The main kit is in an old camera bag that I picked up at a hamfest for $5:

One of the outside side pockets houses a small tripod and some little ground stakes for securing support ropes, etc.

The other outside side pocket houses a small digital recorder and a cellular hot spot:

The front outside pocket houses some rubber coated twist ties that I use for securing a portable lightweight pole, as well as a few POTA brochures, QSL cards and eyeball cards:

The pouch on the inside of the lid contains a 25’ length of coax, a few extra pens and other accessories:

The main chamber houses the KX2 Shack a Box bag, a Maxpedition accessory bag, the AX1 antenna kit and my iPad:

The KX2 bag is the main bit of the kit.  Sometimes, this is the only thing I carry with me (and will often put the AX1 kit inside also):

The rightmost pouch contains the 40m EFHW antenna, which is one of my two workhorses for my activations.

The middle section holds the logging pad, writing utensils, spare wire bits for antenna and counterpoise use, lightweight clips, etc.

The main section of the bag holds the KX2 which includes the internal battery and tuner. Continue reading Field Radio Kit Gallery: W2AEW’s Comprehensive Elecraft KX2 Field Kit

Getting To Know You Series: The Elecraft KX3–My thoughts, notes, and one extreme QRPp contact!

I’m very fortunate in that in the past few years I’ve accumulated a number of QRP radios that I use in rotation when I do park and summit activations.

I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.

Over the years, I’ve written formal reviews about most of the field radios in my collection. In those reviews, I try to take a wide angle view of a radio–to see how it might appeal to a number of types of operators. I highlight the pros and cons, but I don’t focus on my own particular take because, again, my style of operating might not match that of readers. I try to present the full picture as clearly as I can and let the reader decide.

The Getting To Know You series gives me an opportunity to highlight one radio at a time and showcase what I love about it and why it’s a part of my permanent radio collection. After we spend a bit of time talking about the radio, we’ll do a park or summit activation with it!

The Elecraft KX3

I was originally introduced to the Elecraft KX3 at the 2011 Dayton Hamvention–over a decade ago at time of posting!

I was commissioned to write a review of the KX3 for the Monitoring Times Magazine and Elecraft was kind enough to lend me a brand new KX3.

At the time, there was nothing like the KX3 on the market and I felt like I’d just received a radio from the future.

The KX3 offered 160-6 meter general coverage with an optional 2 meter module, ATU, internal AA battery compartment, and roofing filters. The controls were top mounted and current draw in receive was as little as 150 mA. At the time, there was no other radio on the market that could compare with the KX3’s field prowess.

But it wasn’t just its field design that was impressive.

In fact, when Rob Sherwood tested the KX3, it placed at the top of his list which is sorted by Third-Order Dynamic Range Narrow Spaced.

This field radio sported a bullet-proof front end and true contest chops, displacing $10,000+ high-end rigs.

Today, the KX3 (at time of posting) is still number 12 on Rob’s list. An impressive feat!

Herein lies the danger of doing reviews…

I didn’t have the KX3 in my grubby little hands for more than a few hours when I decided I had to buy one. I sold some gear to free up money and I bought the KX3 Elecraft sent me on loan for the full price.

I’ve taken this KX3 on numerous activations and on international travels. It’s a brilliant QRP companion.

These days, it’s in the shack more than in the field because I keep it hooked up to my KXPA100 amplifier. I feel like the KX3/KXPA100 combo is like having a poor man’s K3. As a huge bonus, the KX3 takes up little space on my table and the KXPA100 sits on a shelf–the overall footprint is much smaller than a K3 or K3s. It’s like having a remote head on my desk and works perfectly for my limited space shack.

The KX3 is a stellar, benchmark field radio, so it was great fun to feature it in this video.
