SOTA: First activation of VE6/RA-174

9 Comments

As always there are lots of links within the article. Click one! Click them all! Learn all the things! 

You can see a full video of this activation on YouTube. Use it for CW practice as the footnotes follow the callsigns but only once I’ve gotten it correctly and have transmitted it back.

Our local club runs a repeater network with a dozen repeaters connected hub and spoke style on UHF links. It covers an area approximately 42,000 square kilometers (16,200 square miles) in Southern Alberta. I help to maintain that network and am constantly learning from the smart people that put it together and fix it when it goes awry.

On a Sunday afternoon, in mid-March, I discovered that our club’s VE6HRL repeater at Longview Alberta wasn’t passing audio back to the network, only carrier and some white noise. Local audio was passing along just fine, so the issue is either with the controller or the linking radio. A plan was struck for a service call and to activate this summit at the same time.

Given the repeater is located on Longview Hill, SOTA entity VE6/RA-174, and it is on private land, this summit cannot be activated unless we have reason to be there. Performing repeater maintenance gave us that reason, and so I enlisted the help of Canada’s first double GOAT, VE6VID, to come along with me as it’s a 2 person job to remove a repeater from the rack. We’d activate the summit after the work was complete.

So, on a Sunday morning late in March, the two of us set out in our respective 4x4s to crawl up the road to the summit. In the event you’ve disremembered, I’m in shape -round- and, as a result, my favourite type of SOTA to do is a drive-up. For our repeater sites that are on top of summits, we always bring along two vehicles in case one has mechanical difficulty or gets stuck in the snow. Yes, we have used snowmobiles to do service calls in the past!

The road on the north side of the hill runs up through small valley and does not catch much sun, so the recent snowpack proved to be a small nuisance as we crawled forward. That small nuisance became medium-grade once I got stuck due to lack of forward momentum. A couple of backside-puckering moments later I backed down the hill to take a run at it with more speed and more potty-mouth. Success and no digging with snow shovels was involved.

View from the summit looking West-by-southwest

We arrived at the summit and the view was breathtaking! There were only a few clouds in an otherwise vibrant blue sky, and with the 4″ of snow on the ground it was simply VERY BRIGHT OUT making both of us wish we had darker sunglasses! We entered the repeater building and performed some simple testing in situ and then I powered off the repeater and we removed the gear from the rack and put our tools away a half hour after we arrived. Now we can do SOTA!

The activation zone is quite large at this site and Malen drove a few hundred metres away to set up, providing needed separation between us. He set about to do his thing and I did the same. I brought out my crappie fishing rod/mast and propped it up along the barbed wire fence and set about putting out my VE6VID 66′ EFHW. The folding lawn chair would serve as a table, and a nearby metal cabinet that houses phone lines would hold my Contigo mug and two video cameras.

EFHW running parallel to the fence. The tower is straight in real life, but my camera was not!

With the antenna oriented to the west and sloping downwards and parallel to the very old barbed wire fencing (I call it Tetanus fencing given it’s age and your need for a booster shot if it should puncture your skin), I was uncertain how it would perform. As it turns out I had no cause for concern as I was able to make contacts without too much trouble. I trudged back up the hill to the now-placed lawn chair and finished my set-up.

My “desk” for the activation

I evaluated the bands by listening briefly on the FT8 frequency for 10, 15 and 20m. For me it’s a quick measure of how active the bands are, and dialing off a few kHz or so will reveal how noisy the conditions are. I settled on 20m. Aaand right about then, as if I needed another distraction besides the Canadian Rockies staring me in the face, my HamAlert went off on my phone; regrettably I was unable to hear my friend N4JAW at his activation. As it was too cold to handle my cellphone for typing and spotting, I set about getting spotted via SOTAmat and got on the air. Continue reading SOTA: First activation of VE6/RA-174 →

K3ES Travels: Ten Days of QRP with Compromised Antennas

16 Comments
Ocracoke, NC, home to this iconic lighthouse, was our destination for a week of relaxation.  Ten days of QRP operation was a happy consequence.

Ten Days of QRP with Compromised Antennas

by Brian (K3ES)

At the end of a hard (or even a not-so-hard) winter, Becky and I really enjoy the opportunity to spend a week at the beach with friends.  Even with the cooler and more unpredictable weather late in the off-season, it provides welcome relief from the cold and snow that we often get in northwest Pennsylvania.  This year we chose to visit Ocracoke Island, at the southern tip of the North Carolina Outer Banks.

While driving down and back, I fit in Parks on the Air (POTA) activations at parks in Maryland, Virginia, and West Virginia.  Each of the activated parks was new to me, and  so were their states.  My time at the beach also included daily POTA hunting.  I knew that my radio activity would all be conducted using CW mode, and low power.  All of my contacts on this trip were made with 5 watts, except for a brief stint where I increased power to 10 watts to fight band noise during a longer QSO with my code buddy.  What I did not expect was that all of my contacts would be made using antenna configurations that were less efficient than normal.

At each of the activated parks, I paired my Elecraft KX2 with a brand new Elecraft AX1 vertical antenna.  While it proved very effective at making contacts, the 4 ft high AX1 vertical definitely compromises gain to achieve its tiny form factor for HF operations.  Once we moved into our rented house on the island, we knew that storms were expected.  In fact, gale warnings were issued for our area twice during our week-long stay.  Besides cutting off ferry service to the island, I feared that high winds would bring down any antenna mast that I might try to use.  So, I deployed my shortest wire antenna in a low configuration that I hoped would resist the wind, yet still enable some contacts.  I certainly did not expect it to perform like it had many times before when deployed in vertical or inverted V configurations, but proof would be in the contacts.  I will avoid suspense by saying that this installation was unaffected by the high winds that were predicted and received.

Monocacy National Battlefield – US-0705

Monocacy National Battlefield, US-0705, is located near the junction of Interstates 70 and 270 at Frederick, MD.

Our trip south took us close enough for a visit to our 3-year old grandson and his parents.  Truth be told, any distance would have been close enough, so even though greater-Baltimore is slightly off the direct path, that was the destination for our first day of driving.  On the way to Baltimore, we also passed within a couple of miles of the Monocacy National Battlefield, near Frederick, MD.  So, we spent a couple of hours exploring interpretive displays at the Visitor Center, and of course, activating the park.

As a Civil War history buff, I knew of the Battle of Monocacy, but little about its details.  Briefly, in July of 1864 a small Union force faced off against a much larger Confederate Army led by Lieutenant General Jubal Early.  The Confederates were moving against Washington, DC in an attempt to take the pressure off of the defenders around the Confederate capital of Richmond, VA.  While the battle was a tactical defeat for the Union, it proved to be a strategic victory, because it delayed the Confederate advance for two crucial days.  In that time Washington’s defenses were strongly reinforced, so the Confederate Army withdrew back into the Shenandoah Valley without accomplishing its mission.  More on that later.

A picnic table near a wood line outside the visitor center made a perfect, unobtrusive location to activate US-0705.

For the activation, I set up my station at a picnic table.  A table top tripod supported the AX1 antenna, with a short piece of RG316 coaxial cable connecting it to the KX2.  I operated CW mode with 5 watts of power, and completed the activation with 11 contacts in less than 15 minutes.

The entire station, including table-top AX1, took up less than half of a picnic table.
Logging contacts…

Operating from Ocracoke Island, NC

A week at Ocracoke…

We arrived on Ocracoke on the last ferry run to the island before a Gale Warning shut down service for two days.  We counted ourselves fortunate to be on the island, but gale force winds complicated deployment of antennas.  Except, that is, for the AX1.

K3ES Field Report: Hiking with Molly and discovering a new two-fer activation site!

14 Comments

Many thanks to Brian (K3ES) who shares the following field report:

Molly is on the trail of a POTA activation.  Temperatures are in the 40s, but there is still snow on the ground.

A Hike and a 2-fer

by Brian (K3ES)

When you live in northwestern Pennsylvania, and a February day shows up with the sun shining, moderate temperatures, and nothing pressing on the calendar, it is time to go and enjoy the outdoors.

One of the best ways to do that is to take a hike with your dog.  Hopefully  your dog is like Molly, who doesn’t mind taking a break mid-hike for a Parks on the Air (POTA) activation.  So on Wednesday, February 21 we scheduled an activation and jumped in the truck for a drive to the trail head.  The hike to and from the activation site would be a nice change from the short walks we had been taking to the pond behind our house in the colder weather, and from activating while sitting in the truck.  And, to better share the joy with our POTA hunters, we would make this activation a 2-fer, giving them credit for both the North Country Trail National Scenic Trail (K-4239) and Pennsylvania State Game Land 024 (K-8725).

Molly is ready to go.  She is not at all amused by waiting for me to take pictures.

Since I had hiked the planned route before, both solo, with friends, and with Molly, I expected that the route would be familiar.  Some of it was, and some of it was brand new to us.  You see, the North Country Trail volunteers had been busy since we last hiked as far up the trail as we planned to go.  They had cleared and marked an entirely new route for one section  of the trail, bypassing an old favorite activation site!  So, we got to do some exploring, and we found a new favorite activation site.  Bonus!

Finding a New 2-fer Site

One of the things that I enjoy about POTA is planning my activation.

Since days long ago as a Boy Scout, I have enjoyed outdoor navigation.  Map and compass always fascinated me.  Things have gotten much easier with Global Positioning System (GPS), online maps, and online satellite imagery.  Still, I do most of my activation planning while sitting comfortably at home with a tablet or a computer.  For this trip, finding the newly marked trail (that had not yet been transferred to the online map) presented a bit of a challenge.  While I could follow the marked trail easily, I needed to be sure that I had entered Game Land property so that the 2-fer activation would be valid.

Thankfully, I had access to an app on my smart phone to help me solve this problem as we walked along the trail through the woods.  The On X Hunt app combines GPS, topographic maps, satellite imagery, and tax office databases to identify land ownership (even when the owner happens to be the Commonwealth of Pennsylvania).  Full functionality of this app is not free, but as the owner of a parcel of land, it is something I had elected to pay for.  Once it became clear that the newly marked trail would not quickly rejoin the prior route, I set up the app to record our track on the map.  After confirming that Molly and I had definitely crossed PA Game Land property line (there were no marking signs along the new trail), we went just a bit further, then found a promising spot to set up for the activation.

With a change to the K-4239 North Country Scenic Trail route, we found a new 2-fer site within K-8725, along the partially snow-covered Game Land road that carries this section of the Trail.

Setting Up to Activate

I chose to locate our station in the woods beside a Game Land road that provided the path for the North Country Trail in that particular area.  We set up on the inside of a bend flanked by trees with long overhanging branches.  I placed my chair in the woods on the inside of the bend, and tossed a throw line over a branch on the outside of the bend, then deployed my Packtenna EFRW with 71 ft wire as an inverted V across the road.  I used the throw line to hoist the middle of the radiating wire up about 30 ft, and secured both the feedpoint and the far end of the antenna to nearby trees, about 6 ft off the ground.

Even though I did not expect traffic on this road (shaded areas were still snow covered, and the snow showed tracks only from woodland creatures), I try to deploy my wire antennas high enough that they are not a hazard to others who may travel through.

Temperatures were rising, but with the high only expected to hit 50F, I brought a blanket to give Molly some additional insulation (though she is a rough, tough POTA dog, as a Boston Terrier, her coat is not particularly thick).  I laid out the blanket beside my operating position,  so that it could provide both top cover and insulation from the ground.

Molly is settled in for the activation.

I connected my RG316 coaxial cable to the antenna feedpoint, set up my camp chair next to Molly, set up the radio, and prepared my log book. In very short order, I was on the air, spotted by the Reverse Beacon Network, and logging contacts.

SSB Style: Mark pairs the Elecraft KX3 and AX1 for some challenging activations

Many thanks to by Mark (W2ITG) who shares the following field report:

Elecraft KX3/AX1 Field Report

by Mark (W2ITG)

I’m an avid POTA activator and wanted to try an experiment to see if I could complete an activation using just the Elecraft KX3 & AX1 on 40 & 20m SSB. I’ve seen others do it on CW but not on SSB. My CW learning is not going well by the way.

This was at K-1635 Washington Rock State Park 02-07-2024, with a beautiful view of the NYC skyline approximately 20 miles away.

My 1st attempt was a failure because I ran into SWR issues on 20m when I picked up the microphone & RF was getting into the audio as well. This was with the antenna mounted directly on the side of the radio using a 90 degree elbow connector, the AX1B bipod & an elevated radial connected to one of the case screws of the radio, unfortunately it didn’t work.

It’s a good thing I had brought along my Tuftln EFHW and telescopic carbon fiber fishing pole as well because it saved the day which allowed me to complete the activation. When activating make sure to have a backup plan, so far I have no incomplete activations.

Fast forward to 02-27-2024 I’m making another attempt but using a clamp mount, clamped on to the side of the picnic table, 25’ of ABR Industries RG-316 with built in CMC choke, the Elecraft AXT1 tripod adapter, and an elevated counterpoise.

I was much more successful, but barely. I did get my 10 contacts, 7 on 40m and 3 on 20m. This really took me by surprise as the AX1 is more of a compromise on 40 than it is on 20m.

Radio set up at a different picnic table.
This clamp mount was taken from one of my BuddiStick setups.
Notice the electric fence post in the background to elevate the counterpoise.
The QSO map, it took me an hour and a half to get these 10 contacts.

Using the AX1 was quite the challenge to say the least. It does prove that even with a very limited antenna you can make contacts. My guess as to why it didn’t work as well on 20m, is poor band conditions. Living in the very populated northeast is what I believe allowed me to make more contacts on 40m.

Would I recommend buying this antenna? Most definitely, just as long as you know what it’s limitations are. I will try another attempt, but by trying 2 elevated counterpoise wires instead of 1. This antenna can use all the help it can get.

Field Radio Kit Gallery: WN1C’s Elecraft KX3 Camera Bag Activation Kit

Many thanks to Thomas (WN1C) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, read this post. 

KX3 and Speaker Wire Camera Bag Activation Kit 

by Thomas (WN1C)

For the QRPer’s Field Radio Kit Gallery, this is my KX3 and speaker wire in a camera bag activation kit.

This kit is the continuation of the equipment I used for my Maine ATNO expedition and other activities on that return to my parents almost a year ago. Primarily, it’s a change in bags and an improvement of the audio connection options for more sustained activations. Writing up this kit for the gallery also will probably be an incentive for further change. With how loosely packed it is, there’s space for options! You can see this kit in action on my recent trail activation.

The bag packed and ready for an expedition, even if just a little ways away.

The outside is the discontinued Peak Design Everyday Messenger 15″ v1. I picked this up lightly used on my local craigslist with an eye for expanding the kit contents capabilities. In that endeavor, it has been successful, but concentrating on this configuration to start:

Open the top to reveal the gear packed between dividers!

There’s a certain pattern (that I might not keep following in future re-packings), but the arrangement internally is:

  • Outer pouches: coax, radials, headlamp as necessary
  • Lid flap padded pouch: infrequently used adapters and short cables
  • Left division: antenna(s), throw line and weight, headset, coax, banana cables
  • Mid-left division: logging pouch with paddles and notebook
  • Mid-right division: KX3 with cover and heatsink
  • Right division: power cables, hand microphone, lithium-ion battery banks, LiFePO4 battery pack
  • Flopping around on top: TH-350 HT
  • Front zipper pouch: additional notebooks, earbud headphones, pen, coax, ARRL VE badge

Of course, not all of this gets used at the same time. Different LiFePO4 options with Anderson Powerpole connectors can be substituted. For quick and lighter operating (or when wearing more hats), the headset can be left behind. Anyway, to the details!

Full contents spread out much wider than I usually have space for! Featuring the wooden floor I rarely operate over because apartment living.

So, what is all of this?

Bags

  • Peak Design Everyday Messenger 15″ v1 (discontinued, acquired second hand) with an additional bright red divider stolen from one of my Crumpler camera bags
  • Case Logic accessories pouch from who knows where (underneath the notebook)
  • One of WesSpur’s low cost throw line bags (don’t get it, it’s smelly plastic and falls apart, as shown in the picture)

Radios

  • Star of the show: Elecraft KX3 in the “KX3 Pack” configuration (KX3, KXAT3, KXBC3, MH3) with Side KX KX3 Combo panels and cover, plus an aftermarket heatsink
  • TYT TH-350 tri-band HT (144-222-430 MHz) with bundled SRH-17 tri-band whip

Getting RF Out

  • 2x 28′ (ish) speaker wire on BNC-F to binding posts/banana connector, in use for a while, though now beefed up with a bit of heat shrink and crimped spade lugs
  • 4x 17′ speaker wire shorted together on dual banana plug (radials)
  • 6′ RG-58 BNC-M to BNC-M with a random split ferrite on it from who knows where
  • 2x Pomona banana test leads for occasions of connecting more things together
  • 60′ Marlow Excel Throw Line 2mm (a K4SWL recommendation)
  • WesSpur 10 oz Throw Weight
  • Assorted S-Clip Plastic Carabiners for the speaker wire, throw line, and whatever else needs clipping together
  • CablesOnline 25′ RG-316 with BNC for spare feedline
  • 2 foot BNC RG-316 jumper
  • Adapters: BNC F-F coupler, BNC-M to dual Banana-F/Binding Post, Dual Banana-M to BNC-F, BNC tee, BNC to center Banana-F/Binding Post; all provide options of hacking some options together

Getting Signals In and Out

  • Koss SB-45 Communication Headset (cheaper relative of the popular Yamaha headset; it shows, mostly in the cable quality)
  • Bamatech Bamakey TP-III Rot (an excellent set of dual paddles that can also serve PTT duty) stored in an Altoids Peppermint tin
  • Cable Matters Retractable 3.5mm Audio Cable
  • Hosa YMM-261 Stereo Breakout to allow use of the SB-45 electret mic with another switch wired to a 3.5mm plug for PTT on the KX3 mic port rather than just VOX
  • Custom microswitch to 3.5mm PTT (not very good at its job) using this snap switch
  • Elecraft MH3 hand mic from the kit configuration
  • Old Apple earbuds, headphones only (TRS)

Power

  • Bioenno BLF-12045W 12V / 4.5Ah LiFePO4 pack (can be substituted with the 3Ah pack I also have)
  • Anderson PowerPole to barrel plug for KX3 power
  • Old (sometimes RF noisy) USB Type-A power banks, one with a built-in flashlight (souped up with a much nicer white LED)
  • Misc USB cables, A to Micro-B and C for charging from batteries

Lunch break? Time for a rapid SOTA/POTA activation!

4 Comments

by Vince (VE6LK)

As always there are lots of links within the article. Click one! Click them all! Learn all the things! ? Also, it’s with thanks to the management at QRPer.com who give me this outlet for creative writing.

While on business travel in Northern Alberta recently, I found myself with a slow workday and a few hours owed from lunches not taken that week. A quick plan was hatched and out the door I went after ensuring that all at work was going to be fine without me for 2-3 hours. But before I get to that story…

While travelling to and from this site, I’ve made it a mission to activate as many ATNO [All-Time-New-Ones, ie. never-activated parks] as possible within POTA. I plan these 500km trips with some small side journeys to these parks or natural areas and to break up the otherwise long drive along the foothills of the Canadian Rockies up and down the Highway 22 (aka. Cowboy Trail) corridor. It’s truly a lovely drive and I don’t mind it in the least.

Now back to my late-day lunch break adventure…

With the nearest park to me (VE-3162, Whitecourt Mountain) already activated but only on phone, I figured I’d activate it on CW and do more QSOs than the other activator just for good measure. I can’t believe that a park this close to a townsite had only one activation before I got there to activate it.

If that isn’t enough, it’s also a SOTA entity [VE6/ST-102] with a broad and not-steep slope making the activation zone quite wide. On top of that I can do this two-fer as a drive-up! This worked in my favour as I parked my truck within the activation zone! This SOTA entity had been done a couple of times already so I knew that electrical noise would be my nemesis.

For those of you that may have disremembered, I’m in shape -round- and that shape doesn’t easily climb summits, so a drive-up is totally my kind of summit. But I had to get a move on as there were only two hours left on the Zulu timeclock.  At my hotel room I had more gear, but being nervous nelly that I am at times, I do not leave my KX3 in the room unless there’s a safe. Given that the KX3 gets lonely without companions, I ensure that it always has a battery, antenna and key along for the ride so they keep each other happy as can be 🙂 I had just enough of my portable kit with me to make this happen.

Field Radio Kit Gallery: K8ZT’s Elecraft KX3 Rapid Deployment Kit

6 Comments

Many thanks to Anthony (K8ZT) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, read this post. 

K8ZT Elecraft KX3 Rapid Deployment, Expedition Go-Box

I have been active in portable Field Operations, portable contest operations and POTA for many years. I also like always to have the option of both multiple modes (CW, SSB & DIGI) and multiple bands for my portable operations. I am not a SOTA operator, and although weight is still an issue, this is definitely not a minimalist setup. My preferred method for go-boxes is the rapid deployment model. In this model, almost all interconnections of elements in the kit are already made, and the opening of the case and attachment of the antenna get me on the air in seconds. This model is not designed for airplane baggage handling or other rough transportation but works well in a backpack or carry-on.

Here is a photo (above) of operating FD from Delaware

The design I have used can work with other radios with similar footprints, including Elecraft KX2, Icom 705, Xeigu 5105 or 6100, etc. You could also substitute other similar tackle or tool boxes. I like working with plastic cases because they are lightweight and easily modified. I have put together a slideshow on my go-box with instructions and suggestions at tiny.cc/rapidkx3.

I used the Plano 135402 4-BY™ 3500 Stowaway® Rack System tacklebox.

A very similar box is the Harbor Freight- STOREHOUSE Toolbox Organizer with 4 Drawers.

Securing the KX3 to the box was easily accomplished by substituting two longer nylon thumbscrews for the two shorter manufacturer-supplied ones. These screws extend through the case and screw into KX3. Nylon was chosen to allow easy customized lengths. The BNC antenna extends out of the case.

In addition to using the tackle box for my go-box, I also got the four insertable clear plastic containers. With the radio installed, I still have room for one container in its original position.

I can load a lot of extra supplies in these containers. You can even set up each of the four for different types of operations.

The top of the tackle box is storage space for my LiFEPO4 battery and other items. The contents can change depending on the planned operation. Here, you can see the Mic for phone operations and a DigiRig Mobile External Sound Card Interface for FT8. If doing a contest-type operation, I usually use a headset with a mic, and you can see the push-to-talk foot switch in the box ( a source of cheap light foot switches is eBay Tattooing foot switches).

I have also run cabling from the radio’s connections (Mic, Key, Headphone & Serial port) into the top area to make connections easier. To facilitate multiple connections, each uses a 3.5 mm plug 90° (connection to radio) and a splitter with two 3.5mm sockets to connect accessories. I used a label maker to label each connector’s socket ends.

Note the quick reference diagram of the KX3 mounted in the lid of the go-box. This is something I do with all of the go-boxes I build. I use tiny bungee cords on larger go boxes to securely store manuals in lid space.

I like computer logging, especially for more extended contests or Field Day operations. I use the computer to interface with the radio for this operation. This also provides me with a computer to do digital modes. I have found laptops that work with 12-volt DC to extend the usable time when AC is unavailable. I have also found PC Power Banks with 20 V DC output that can run most laptops for 24+ hours in conjunction with the laptop’s internal battery. One accessory I find essential is a simple USB storage drive with the following:

  • Installation file for any computer programs I will be using (Logging software, WSJT-X, JT-Alert, etc.)
  • Elecraft KX3 Control Utility (to program macros, make setting changes, etc.)
  • Rig computer software Drivers for all of my radios
  • Firmware for all of my radios (just in case)
  • PDFs of all user manuals for any equipment I am using. Although paper manuals do not require a computer, they are heavy, easily damaged and especially not computer-searchable for the exact item I need to diagnose my issue.

The other thing the USB drive can facilitate is the emergency use of a loaner computer, which would have none of the software I would need installed.

I use a variety of antennas with my kit, but my default is a random-length Endfed connected directly to KX3’s antenna jack with a BNC splitter. My support is a 7-meter fiberglass collapsible fishing pole. Here is a table with alternative random antenna lengths to try- link#1 and  link #2

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.

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

16 Comments

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.

For this Getting To Know You report and video, I decided to activate one of my favorite local parks on September 12, 2023: the Vance Birthplace. Continue reading Getting To Know You Series: The Elecraft KX3–My thoughts, notes, and one extreme QRPp contact! →
